#

Hmm. Okay... So for an order, a user creates an object containing form data, and also an object containing data for what they want to actually order

#

So shouldn't there be a relationship between that form data and the stuff they're ordering?

#

Specifically, I'd say doing something like... And someone correct me if this is bad design here

#

For each order item (so the pizza), create a relationship to the order (e.g. the form data)
On the form data, add a method to get all order items referencing the order (this is basically a calculated field and would use a query)
Add that method to what's displayed in the admin panel.

For steps #2 and #3, see this: https://books.agiliq.com/projects/django-admin-cookbook/en/latest/calculated_fields.html

frigid egret Jul 19, 2019, 9:56 PM

#

Ok, i'll try that.

#

Hm, wait

#

I don't get the first part

#

I have a model with foreign keys to both pizza object and user form. So I already have those.

prime ridge Jul 19, 2019, 9:58 PM

#

So you have a third object that foreign keys to both?

frigid egret Jul 19, 2019, 9:58 PM

#

yes

prime ridge Jul 19, 2019, 9:58 PM

#

What if they want more than one pizza?

frigid egret Jul 19, 2019, 9:58 PM

#

And it adds its own data as well

#

class OrderItem(models.Model):
    user_form = models.ForeignKey(Order, on_delete=models.CASCADE)
    item = models.ForeignKey(Pizza, on_delete=models.DO_NOTHING)
    size = models.CharField(max_length=100)
    quantity = models.CharField(max_length=100)

#

Size and Quantity are fields it gets from json since that's user choice

prime ridge Jul 19, 2019, 10:00 PM

#

So for each order, with the way you've designed it, you have...

One user_form
One or many Pizzas.
One or many OrderItems (equal to the number of Pizzas)

#

Yes?

frigid egret Jul 19, 2019, 10:00 PM

#

not just for each order but for each item in the order.

#

say, if a user were to add 3 types of pizzas to the cart and then make that order, there are 3 objects created, for each pizza.

#

And they all contain a link to related pizza object, user form and user choice of size and quantity

prime ridge Jul 19, 2019, 10:02 PM

#

Three Pizza objects. For the order, right. But also three OrderItem objects -- one for each pizza. Correct?

frigid egret Jul 19, 2019, 10:02 PM

#

pretty much

prime ridge Jul 19, 2019, 10:03 PM

#

But they all have a common user_form. Hmm.

#

You may have too much abstraction.

frigid egret Jul 19, 2019, 10:03 PM

#

Well, OrderItem is referencing to each pizza so Pizza objects stay the same

#

Let me clarify.

#

Say there are 5 pizzas on the website, each can be created in the admin panel. Then when a user orders a pizza, there are still 5 of them. But OrderItem now knows which one the user chose.

prime ridge Jul 19, 2019, 10:05 PM

#

Ok. So this is not a dominos create-your-own topping kind of thing. Management provides the menu

frigid egret Jul 19, 2019, 10:05 PM

#

I could post my code if that helps

ruby palm Jul 19, 2019, 10:06 PM

#

Sorry I thought this channel wasnt in use

frigid egret Jul 19, 2019, 10:06 PM

#

@prime ridge yep, it's a basic web-store. It could have been shoes instead of pizzas. 😄

prime ridge Jul 19, 2019, 10:07 PM

#

I'm starting to understand the reasoning behind your design decisions (my brain went to "oh well why don't we [do what you did]") but I think this could be simplified thonk

frigid egret Jul 19, 2019, 10:08 PM

#

But there are multiple OrderItem objects for each order and I still don't get how to group them into a single item in admin panel

prime ridge Jul 19, 2019, 10:08 PM

#

Django's a little funny about storing lists, right? Like, if you could have a list or a dictionary field, you'd just need one order object for each order.

#

Those fields actually exist but they're specific to PostgreSQL (https://docs.djangoproject.com/en/2.2/ref/contrib/postgres/fields/)

frigid egret Jul 19, 2019, 10:09 PM

#

Yea, but because I have those extra fields: size and quantity, it makes it tricky so I decided to separate those objects

#

Instead of having a list of pizzas and several sizes and quantities.

#

I have been working with sqlite thise whole time. Databases are out of my knowledge so far.

ruby palm Jul 19, 2019, 10:11 PM

#

:thonk:

#

:thonk:

#

Blitz do you have nitro discord?

prime ridge Jul 19, 2019, 10:12 PM

#

Nah but I got that from another discord

#

So, okay, let me just try to solve the problem as you have it instead of, erm, trying to tell you how you should redesign your entire project, gimme a sec to think

#

All OrderItems reference one user form. So the user form is the common element shared between all things relating to the order

frigid egret Jul 19, 2019, 10:13 PM

#

I mean if that's poor design choice, I'd like to know how to not make that mistake again.

prime ridge Jul 19, 2019, 10:14 PM

#

as mentioned before, you can add a calculated field to the user form model (call it an order model)

#

to get all OrderItems that reference it (a django query)

#

(this was step #2 above, maybe slightly modified)

#

then just add that field to the admin panel (step #3 above)

frigid egret Jul 19, 2019, 10:17 PM

#

Ok, so I can display my Order objects in admin panel and then inside them have a list of related pizzas?

prime ridge Jul 19, 2019, 10:18 PM

#

(assuming user form data == order) yes

frigid egret Jul 19, 2019, 10:18 PM

#

Do i do it with Inline?

#

Here's my code, to be on the same page:

#

class Order(models.Model):
    name = models.CharField(max_length=100)
    phone = models.CharField(max_length=100)

    def __str__(self):
        return f"{self.name}, {self.phone}"


class OrderItem(models.Model):
    user_form = models.ForeignKey(Order, on_delete=models.CASCADE)
    item = models.ForeignKey(Pizza, on_delete=models.DO_NOTHING)
    size = models.CharField(max_length=100)
    quantity = models.CharField(max_length=100)

    def __str__(self):
        return f"item = {self.item}, size = {self.size}, quantity = {self.quantity}" \
            f", order = {self.user_form}"

prime ridge Jul 19, 2019, 10:19 PM

#

I had something like this I implemented very poorly and ended up hating it but lemme go get the code while you do that

#

right. So you'd add a method to order to query all OrderItems with user_form referencing that order object -- lemme see what I can dig up

#

    def flags(self):
        return Flag.objects.filter(event=self.id)```

#

So, modifying this...

#

    def order_items(self):
        return OrderItem.objects.filter(user_form=self.id)```

#

You'd add that method to order

frigid egret Jul 19, 2019, 10:21 PM

#

Ok, yea, that worked... Not perfect, but at least it's definitely closer to what I wanted to have

#

Here's what I did to my admin.py

#

class OrderItemInline(admin.TabularInline):
    model = OrderItem


class OrdersAdmin(admin.ModelAdmin):
    list_display = ('name', 'phone')
    inlines = (OrderItemInline,)


admin.site.register(Order, OrdersAdmin)

prime ridge Jul 19, 2019, 10:21 PM

#

Let me show you a whole lot of ugly. I hate this thing but it should give you some ideas

frigid egret Jul 19, 2019, 10:22 PM

#

Ok

#

Uh...

prime ridge Jul 19, 2019, 10:24 PM

#

Key part of this: I added a readonly field called "flags_html" which basically iterated over all of the related flags and provided a list output of them. The point is, you can override the HTML output handles the field you tack-on

#

so, if you don't like what it says or how it looks, there are lots of ways to override it

#

but yeah the way I did it was not pretty

frigid egret Jul 19, 2019, 10:26 PM

#

Ok. Well, I'm trying to use standard views as much as possible. Didn't have to override any html yet.

prime ridge Jul 19, 2019, 10:26 PM

#

lollll

#

good call

frigid egret Jul 19, 2019, 10:27 PM

#

Since I don't know natural limitations of Django so far.

prime ridge Jul 19, 2019, 10:27 PM

#

Yeah neither did I which is probably how I ended up with that hack deletes my shame

frigid egret Jul 19, 2019, 10:27 PM

#

Well, now I know what to avoid if possible 😄

#

And thank you for pointing me in the right direction!

prime ridge Jul 19, 2019, 10:28 PM

#

#

good luck

What is the {% block content %} {% endblock content %} for in django template language?

frigid egret Jul 19, 2019, 10:28 PM

#

instead of, erm, trying to tell you how you should redesign your entire project

#

How would you approach the task?

#

@ruby palm You use those tags to transfer your html content to another page. Don't remember the name of this method.

ruby palm Jul 19, 2019, 10:31 PM

#

extends?

frigid egret Jul 19, 2019, 10:31 PM

#

Oh, right

prime ridge Jul 19, 2019, 10:32 PM

#

Hmmm, I'm not confident in saying I have one objective right way to do it but I might just serialize the order as JSON and store it in a JSONField (postgres only) -- or just put it into a CharField (any db).

{pizza_id: quantity} -- so like {1: 2, 3: 1} to say 2 of pizza id 1, 1 of pizza id 3. Then just build off that.

frigid egret Jul 19, 2019, 10:32 PM

#

@ruby palm https://tutorial.djangogirls.org/en/template_extending/

prime ridge Jul 19, 2019, 10:32 PM

#

So then you just have one object per order, with any complicated listy information being serialized

@ruby palm to chime in blocks are cool because it lets you do stuff like...

base.html

{% block head %}
<head>
    <title>MySiteName</title>
    {% block extra_head %}{% endblock %}
</head>
{% endblock %}
...```

home.html
```html
{% extends 'base.html' %}
{% block head %}
<head>
    <title>Ha I overrided the entire head</title>
</head>
{% endblock %}
...```

other.html
```html
{% extends 'base.html' %}
{% block extra_head %}
<script async src="https://HaImJustAddingToTheHeadNotReplacingIt.com/script.js"></script>
{% endblock  %}
...

ruby palm Jul 19, 2019, 10:39 PM

@cursive cairn Wait, you're wanting to access someone's local file system using a webserver on a remote machine??? Not sure what you're aiming for.

cursive cairn Jul 20, 2019, 5:54 PM

#

@prime ridge I’ll try to clarify. The server is run locally. I want the user to select a folder on their computer so the local server can analyze files at that folder without moving files (large file volume).

prime ridge Jul 20, 2019, 5:54 PM

#

the server runs on the client computer

cursive cairn Jul 20, 2019, 5:54 PM

#

Everything is run on clients machine

prime ridge Jul 20, 2019, 5:54 PM

ok

#

Any reason you're choosing to use flask for this?

cursive cairn Jul 20, 2019, 5:56 PM

#

Not necessarily. Just familiar with Flask

#

And because I’m familiar, I’ve already built a large portion of my program on Flask

prime ridge Jul 20, 2019, 5:56 PM

#

Well, I figure you can do one of two things. You could use tkinter for the file selection bit (assuming you want it to just be a terminal and a file selector)

is the flask app using, um

a web interface?

#

@ruby palm not every tag has a visual impact, many of them don't

#

and they are just to make the code more readable, so you don't have a million divs

#

https://www.w3schools.com/html/html5_semantic_elements.asp

#

they are "semantic" tags

#

I assume they also help search engines to look for certain tags and grab the contents, like Google does when it shows you a card of something you typed in, but that's speculation, I haven't examined the HTML of any webpage to see if this is true

lime thicket Jul 21, 2019, 1:00 AM

The name attribute is used in form posts to identify that fields data

#

Ohhhh okok

#

Thanks

#

Then what are IDs for? Like the id that is in the image

keen sphinx Jul 21, 2019, 2:35 AM

#

does anyone know how Flask handles generators when streaming with Response(somethingIterable(),mimetype='whatever')? does it automatically "unwrap" anything that recognizes as bytes?

#

because if something yields an integer or something and I cast it to bytes inside the Response, it works but what it prints is the address of the iterable object

#

which of course is ugly but I'm just trying to understand how it works

lime thicket Jul 21, 2019, 1:03 PM

#

@ruby palm an ID could be used for CSS or JavaScript manipulation easier then an attribute like name. Sometimes you need to interpret data between the form and your API and leveraging the ID with $(‘#<ID>’) makes that easy

Looks like they are tuples

Delimited by a space

#

Each element uses a comma delimiter

#

I.think the ones at the bottom are weird cause those are for clues etc

#

It's readable as plain text to me (in a browser) so you should just be able to do a get request and simple string parsing

Hi all

#

I need an advice on managing inlines in Django

#

I'm working on a dummy pizza store website for practice.

#

I have orders which contain user data, and then in each order I have a list of pizzas. That's where I use Inline to get pizza objects.

#

I would like to add anew field to the order list: total price. But first I have to get all pizza prices, multiply them by quantity. Basically, I have to get those values from an inline object and I only know how to display that said inline object.

ruby palm Jul 22, 2019, 1:14 AM

#

@lime thicket Ok, thank you!!!

#

What does mean that HTML its an hypertext language?

ruby palm Jul 22, 2019, 3:36 AM

#

If there are classes, why do we need ids in HTML and CSS?

proper hinge Jul 22, 2019, 3:38 AM

#

As you may know, IDs are unique unlike classes

#

Meaning only one element may have a certain ID

#

But it's really a semantic difference. Nothing is stopping you from using classes for everything, even if some of those classes are unique

#

But that's just bad practice

ruby palm Jul 22, 2019, 3:51 AM

#

Oh ok

#

Thank you so much!!

#

And what's the difference between span tags and div tags?

proper hinge Jul 22, 2019, 3:56 AM

#

I believe the difference is in how they are styled by default

#

spans are displayed inline while divs are blocks

#

Something like that

#

so you could use a span if you want to have some inline element in a paragraph of text

ruby palm Jul 22, 2019, 3:58 AM

Oh, ok!! Thank you, kind sir!

Hey guys im trying to make a website to host my portfolio, I was wondering if you had any suggestions as to where to store my projects to link on the website

polar wasp Jul 22, 2019, 2:30 PM

#

it also makes a difference for nesting if you have other elements and are using HTML5 rules, a div can't nest inside a <p> tag, for example, and will automatically close the preceding one

Mesha. A github profile is usually whats linked to. If you mean hosting them, then a cheap vps is an option

Hi all

#

I'm trying to run custom authentication on my website (study project)

#

So that users only need phone number and password to be able to register and log in

#

Here's my models.py:

#

from django.db import models
from django.contrib.auth.models import (
    AbstractBaseUser, BaseUserManager
)


class UserManager(BaseUserManager):
    def create_user(self, phone, password=None, is_staff=False, is_admin=False, is_active=True):
        if not phone:
            raise ValueError('User must have a phone number')
        if not password:
            raise ValueError('User must have a password')

        user_obj = self.model(
            phone=self.phone
        )
        user_obj.set_password(password)
        user_obj.staff = is_staff
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj

    def create_staffuser(self, phone, password=None):
        user = self.create_user(
            phone,
            password=password,
            is_staff=True,
        )
        return user

    def create_superuser(self, phone, password=None):
        user = self.create_user(
            phone,
            password=password,
            is_staff=True,
            is_admin=True,
        )
        return user


class User(AbstractBaseUser):
    phone = models.CharField(max_length=100, unique=True)
    name = models.CharField(max_length=100)
    email = models.EmailField(max_length=100, unique=True)
    active = models.BooleanField(default=True)
    staff = models.BooleanField(default=False)
    admin = models.BooleanField(default=False)

    USERNAME_FIELD = 'phone'
    REQUIRED_FIELDS = []

    objects = UserManager()

    def __str__(self):
        return self.phone

    # def get_full_name(self):
    #     return self.phone
    #
    # def get_short_name(self):
    #     return self.phone

    @property
    def is_active(self):
        return self.active

    @property
    def is_staff(self):
        return self.staff

    @property
    def is_admin(self):
        return self.admin

#

I also added AUTH_USER_MODEL = 'users.User' to my settings.py

#

But when I try to register a new superuser (I've wiped my database to avoid conflicts) it gives me this error:

#

Anybody here have any experience sending an PIL generated image to your website and displaying it?

#

I've successfully sent my image and received it but since its in binary I can't just display it.

#

Might not even be binary though, I have a hard time reading it. Anybody remember how you did it?

turbid solar Jul 23, 2019, 10:48 AM

#

how do i differentiate users in flask?
for example, i have a form that saves the data as JSON file
i want to name the json file differently per user, so that when the y try to change it, the server knows which JSON file to change

vagrant adder Jul 23, 2019, 11:03 AM

#

There is this thing called database

turbid solar Jul 23, 2019, 11:14 AM

#

can i use sessions?

vagrant adder Jul 23, 2019, 11:15 AM

#

Where are you storing user data

turbid solar Jul 23, 2019, 11:17 AM

#

server side

#

i guess i can use sessions

#

thanks :> i didn't get how sessions work clearly at first since i thought all users access the same dictionary.

vagrant adder Jul 23, 2019, 11:28 AM

#

Umm

#

You doing me a confusion

turbid solar Jul 23, 2019, 11:30 AM

#

sorryy.. i thought if i set the session['user'] when i access the login page from my computer it would replace the session['user'] that was setted when i logged in from my phone

#

i guess that wasn't the case

vagrant adder Jul 23, 2019, 11:30 AM

#

Wait

#

Let's go from beginning

#

What do you want to do

turbid solar Jul 23, 2019, 11:31 AM

#

i want to differentiate each user

vagrant adder Jul 23, 2019, 11:31 AM

#

You gonna need a storage on your server

#

And most common case to deal with that is database

turbid solar Jul 23, 2019, 11:32 AM

#

i didn't see the need for a database since it's only a local/LAN webserver.

vagrant adder Jul 23, 2019, 11:32 AM

#

Yeah but if you save something on a session, that's gonna be available only on one browser session

#

Only one user

turbid solar Jul 23, 2019, 11:33 AM

#

once the browser is closed, the session is gone?

vagrant adder Jul 23, 2019, 11:33 AM

#

Yes but some data is remembered

turbid solar Jul 23, 2019, 11:33 AM

#

i'm going to use the session to differentiate users

vagrant adder Jul 23, 2019, 11:33 AM

#

I would strongly recommend making a database

turbid solar Jul 23, 2019, 11:33 AM

#

then save the json on a folder named using the username stored in session

vagrant adder Jul 23, 2019, 11:33 AM

#

Databases are quite fast nowdays and easy to setup

turbid solar Jul 23, 2019, 11:34 AM

#

i'd consider that too

#

if i see some inconsistencies with the flow i want to implement

#

thankss

vagrant adder Jul 23, 2019, 11:35 AM

#

Session only lives in a browser, not on a server

turbid solar Jul 23, 2019, 11:35 AM

#

lemme make some pseudo code

#

app routing on /login

set session['username'] = form data

app routing on /settings

create json from form data
save on folder named session['user']

vagrant adder Jul 23, 2019, 11:38 AM

#

Are you gonna use only one device or more

turbid solar Jul 23, 2019, 11:38 AM

#

more

vagrant adder Jul 23, 2019, 11:38 AM

#

Then use a database my dude

#

What lives in one's session, doesn't live on other's

turbid solar Jul 23, 2019, 11:39 AM

#

What lives in one's session, doesn't live on other's

hi anyone here?

#

am working with flask

#

from SecondTest import func1
from SPEED2 import NetSpeed
import time
import multiprocessing
app = Flask(__name__)


@app.route('/')
def student():
   return render_template('input.html')


@app.route('/result', methods=['POST', 'GET'])
def result():
    ip1 = request.form['IP1']
    sp1 = '8200'
    ip2 = request.form['IP2']
    sp2 = '8210'

    print(ip1)
    print(ip2)

    speed = multiprocessing.Value('f', 0)
    ping = multiprocessing.Value('f', 0)
    endFlag = multiprocessing.Value('i', 0)
    endFlag.value = 1

    manager = multiprocessing.Manager()
    shared_list = manager.list()

    p1 = multiprocessing.Process(target=NetSpeed, args=(ip1, sp1, speed, ping, endFlag))
    p2 = multiprocessing.Process(target=func1, args=(ip2, sp2, speed, ping, endFlag, shared_list))

    p1.start()
    time.sleep(20)

    p2.start()
    p1.join()
    p2.join()

    # print(shared_list)
    return render_template("result.html", shared_list=shared_list)


if __name__ == '__main__':
    app.run(debug=True)

#

what the above program does is: get 2 IP address as input, do some process. Process p1 updates its values to Process p2.

#

Process p2 has access to shared variable named - shared_list, whose value changes every 30sec. I want to display this dynamically changing shared_list in the front end.

#

   <body>
    <form action = "/result" method = "POST">
    <p>IP address and Port number of device 1 <input type = "text" name = "IP1" /></p>
    <p>IP address and Port number of device 2 <input type = "text" name = "IP2" /></p>
    <p><input type = "submit" value = "submit" /></p>
</form>
   </body>
</html>```

#

Above input.html takes 2 IP address as input.

#

IN SHORT - PROCESS WHICH HAS ACCESS TO SHARED_LIST, KEEPS CHANGING THE VARIABLE'S VALUE'. I MUST DISPLAY THE CHANGES IN FRONT END *

#

how do i display the changes

stray nexus Jul 23, 2019, 4:07 PM

#

you have to either pool the server from the client periodicaly, or use some kind of event to send data at the server intiative.

hey guys! I made something that manipulates data and calculates a few statistics based on a postcode.
Expected behavior: user inputs a postcode (44400) and an essence type (gazole)

# the correct answer is this ((name, address), (average prices over 12 months)) /thanks @ jojo#2133:
(('E.Leclerc Station Service', '10 Rond-Point de la Corbinerie, Rezé'), [1.348, 1.319, 1.317, 1.352, 1.41, 1.418, 1.395, 1.401, 1.427, 1.475, 1.426, 1.358])
(('E-Leclerc service station in Reze Cedex', '1 rue Ordronneau, Route de Pornic, Rezé'), [1.347, 1.309, 1.321, 1.36, 1.411, 1.416, 1.387, 1.411, 1.432, 1.473, 1.408, 1.329])
(('E.Leclerc Station Service', '10 Rond-Point de la Corbinerie, Rezé'), [1.343, 1.312, 1.311, 1.342, 1.414, 1.412, 1.391, 1.398, 1.427, 1.473, 1.408, 1.354])

The issue here, is that, when I launch my flask server, it does correctly starts and on user input, follows the expected behavior — but only on the first time, when I go back, refresh the page (anything unless I restart the flask server (dev or prod btw)), it appends to the html output in a weird way, and does not reset the content, and display the nth request (see attached)

Flask script gist : https://gist.github.com/ceIia/7780c207c30e51d57ef8b817ad6e4d34 (I only added the flask related files, not the actual scripts, because I tried them directly from the CLI and it was working fine, giving the expected results everytime- which made me suppose it does come from the Flask server somewhere? Tell me if you need anymore information).

Thanks a lot for taking the time to read this, sorry for the wall of text!! 😅

I don't see anything wrong with your flask script, try printing the results from yearly_average_constructor after each request

I suspect something in there is not resetting

vagrant adder Jul 24, 2019, 9:15 AM

it does not get reset?

i think that's because you are constantly writing to a file and between requests it is filled with data from previous requests

For about us

#

Try position absolute

native root Jul 24, 2019, 10:25 AM

#

Z-index only functions on elements that are positioned something other than "static", which is the default

#

"relative" might be more helpful here

#

Hmmm... I tried relative and absolute on Leaders class but it still doesn't work.

📎 unknown.png

native root Jul 24, 2019, 10:51 AM

#

We'd need to know a bit about the underlying html then

#

Z-index controls the relative placement of "stacking contexts" in their parent "stacking context"

#

so, if you've already got a container that doesn't also contain the "about us" but is also positioned nonstatically, then that one must be greater in z-index than the about us label

#

also note opacity and transforms trigger stacking contexts

CSS stacking contexts: What they are and how they work

Stacking contexts are an aspect of CSS that trips up most developers. I don't think I fully understood them until I wrote the layout chapter of CSS Master. Sure, I understood that z-index required position to be something besides static. But that's about as far as my comprehe...

you can't break out of a z-index layer with z-index, so since <header> creates a new context that is below About-us's context, it doesn't matter what value that your leaders gets, since its flattened down into the one that <header> uses when it's compared to anything outside of <header>

I have a question. Is this possible? I'd like to make an image transparent when I would hover on a text which is somewhere else (on the same website ofc)

native root Jul 24, 2019, 11:30 AM

#

Depends on your constraints

#

If the image is next to or inside the hovered element, you can do it with css, via the adjacent sibling combinators and similar.

#

if it is not, then you can use javascript

@native root : (message from 11:13am) yearly_average_constructor outputs the wrong behavior, so it actually might not be flask you're right, @vagrant adder. The thing is, I have in every python script called by the main Flask script, a variable_name = [] (or 0) at the start to make sure it starts clean everytime...
(I updated the gist to add the file from which it constructs the wrong list, if you maybe have an idea of what could be wrong)

@native root 😄 fak! i spend 2h 😄

native root Jul 24, 2019, 12:11 PM

#

pump_list and raw_array should be inside the function

#

unless you wish to keep the sticky behavior for some other module, at which point you can write a reset() function that reinitalizes them. If you do that, make sure to use global

hey! it's me again 😅
found this great tutorial online about chart.js and flask -> https://blog.ruanbekker.com/blog/2017/12/14/graphing-pretty-charts-with-python-flask-and-chartjs/
here's my issue: I have a list of gas stations with different datasets everytime (as shown on the screenshot): what would be the workaround to reset the js script datasets to generate a new graph everytime?

also, at the end, i'll be supposed to generate a big graph with every line stacked, which is done by giving every dataset at once to chart.js, and even that is another whole thing.

what would be the best workaround this? should I have multiple instances of the js script running for each graph? (chart.js docs : https://chartjs.org/docs/latest/)
(sorry again for the 2nd wall of text today- thanks so much for the help you guys gave me: i've progressed so much in python over the last two weeks thanks to your help)

Graphing Pretty Charts With Python Flask and Chartjs - Ruan Bekker...

I am a big sucker for Charts and Graphs, and today I found one awesome library called Chart.js, which we will use with Python Flask Web Framework, …

flint breach Jul 24, 2019, 9:47 PM

#

you simply make a function

#

that has input params the parameters of the graph

#

and renders the graph for the specified input

#

if for example you're scraping data, and a user inputs a link for a specified petrol station

#

you simply fetch the data, and return it, and then write a js function to handle the data with the specified input

#

and that's that

vagrant adder Jul 24, 2019, 10:24 PM

#

make a request to the database and collect the data.
After that shape data in any way or form you need and just pass it as argument in chart.js Chart object

#

chart.js updates realtime

Hello

#

Well this is embarrasing

#

Im gonna to ask a question I already asked in this channel, two weeks ago

#

Because I forgot what the answer is and as I'm a dumbass I didn't save it into any archives

Is there a free source for learning data structure fundamentals and/or pattern designs?

@vagrant adder @flint breach yeah- but that would not work if I have to display multiple graphs at once

flint breach Jul 25, 2019, 8:11 AM

#

Why not

vagrant adder Jul 25, 2019, 8:14 AM

#

Why

#

Make multiple requests

#

On my internship i had to graph jenkins tests and i used mutiple charts at once

flint breach Jul 25, 2019, 8:37 AM

#

exactly

smoky swan Jul 25, 2019, 8:45 AM

#

I think I'm not following on the last part- I would have as many copies of the js script in my html page as I have graphs rendered?

vagrant adder Jul 25, 2019, 8:46 AM

#

Yeah

#

Although, you can make 2 instances of Chart object in a single js script

#

But i'd recommend separating each instance im separate scripts

smoky swan Jul 25, 2019, 8:48 AM

#

hmmm- i hope it doesn't affect performance too much

vagrant adder Jul 25, 2019, 8:48 AM

How do I turn on debugging in Flask using Powershell? I have tried $env:FLASK_ENV="development" but then I get an error No module named C:\Users\shado\python-scripts\microblog\venv\Scripts\flask

vagrant adder Jul 25, 2019, 3:33 PM

#

Try set FLASK_ENV="development"

#

@native tide

native tide Jul 25, 2019, 3:33 PM

#

that doesn't do anything

#

$env:FLASK_ENV="development" is how to set the variable in Powershell

vagrant adder Jul 25, 2019, 3:34 PM

#

Nope

#

It's set

#

And also, try pip installing flask in your venv

native tide Jul 25, 2019, 3:34 PM

#

it's not set because I've already been down that road

#

$env actually changes the mode but set does not

vagrant adder Jul 25, 2019, 3:35 PM

#

It worked for me

native tide Jul 25, 2019, 3:35 PM

#

it doesn't for me

#

I can turn debug mode on I just can't get the app to run

#

and flask is already installed

#

I can run the application outside of debug mode

vagrant adder Jul 25, 2019, 3:36 PM

#

You can set in your config.py DEBUG = True

native tide Jul 25, 2019, 3:37 PM

#

didn't do anything

vagrant adder Jul 25, 2019, 3:38 PM

#

Is your code on github?

#

And do you have git bash

native tide Jul 25, 2019, 3:38 PM

#

no I'm using a tutorial, but the tutorial code is on github

#

I have gitbash but I don't know how to use it

vagrant adder Jul 25, 2019, 3:40 PM

#

Oh thank god

#

Now

#

Do export FLASK_ENV='development'

native tide Jul 25, 2019, 3:41 PM

#

in gitbash?

#

can I use gitbash as an interpreter?

#

export gives an error in Powershell

vagrant adder Jul 25, 2019, 3:42 PM

#

Think of bash as better powershell

#

Im bash do export line

native tide Jul 25, 2019, 3:43 PM

#

I have no idea how to get this set up in gitbash

#

is git copying my Powershell directory?

vagrant adder Jul 25, 2019, 3:44 PM

#

export FLASK_ENV='development'

#

Git is vcs

#

Bash is better powershell

native tide Jul 25, 2019, 3:45 PM

#

vsc?

vagrant adder Jul 25, 2019, 3:45 PM

#

What publishes your code on github

#

That's git

native tide Jul 25, 2019, 3:45 PM

#

when I do export it doesn't do anything

vagrant adder Jul 25, 2019, 3:45 PM

#

Export in bash sets env vars

native tide Jul 25, 2019, 3:46 PM

#

I don't understand what you're asking because I don't know how to set directories or run the program from git

vagrant adder Jul 25, 2019, 3:47 PM

#

py run.py

native tide Jul 25, 2019, 3:47 PM

#

if I don't have my environment activated in Git how can I work with the variables?

vagrant adder Jul 25, 2019, 3:48 PM

#

activate env by typing source venv/Scripts/activate

native tide Jul 25, 2019, 3:48 PM

#

Okay you have got to start at the beginning here

#

I don't even know how to set directories in Git Bash

vagrant adder Jul 25, 2019, 3:49 PM

#

What do you mean by setting directories

native tide Jul 25, 2019, 3:49 PM

#

Setting the directory for my Flask application

#

if I just start setting variables outside of the app it's not going to do anything

#

I don't know how to use git bash at all so this is really confusing to me

#

I figured that part out but now I'm stuck trying to get it to run without debug

#

alright @vagrant adder I got everything working in git bash then set export FLASK_DEBUG=1 and got the same issue

vagrant adder Jul 25, 2019, 4:01 PM

#

You have to setup debug withing app context

#

Not flask

native tide Jul 25, 2019, 4:01 PM

#

How do I do that?

#

I also realized during this that the guy who made the tutorial has been using git bash for his examples

#

@vagrant adder

vagrant adder Jul 25, 2019, 4:17 PM

#

app.debug = True

#

Inside __init__.py

native tide Jul 25, 2019, 4:17 PM

#

Do you know how I get get debug turned off before I try that?

#

I used export and now it's permanently set to on

#

setting app.debug to true in the init.py didn't do anything @vagrant adder

vagrant adder Jul 25, 2019, 4:20 PM

#

debug turn off?

native tide Jul 25, 2019, 4:21 PM

#

I just restarted git bash

vagrant adder Jul 25, 2019, 4:21 PM

#

export FLASK_ENV='production'

native tide Jul 25, 2019, 4:21 PM

#

yeah I tried that and it stayed on

vagrant adder Jul 25, 2019, 4:23 PM

#

Now restart git

#

And it should turn off permanently

native tide Jul 25, 2019, 4:24 PM

#

I need it on though

vagrant adder Jul 25, 2019, 4:25 PM

#

Ffs

#

Do you want it on or off

native tide Jul 25, 2019, 4:25 PM

#

Did you not read my original question?

#

I'm having trouble because I can't get debug to work in Powershell

#

and now we've determined it also does not work in Git Bash

#

and gives me the same problem

#

Regardless I'm having the SAME ISSUE in git bash

Are you working with 1 file or more files

#

a lot of files

#

I'm running the script using flask run

#

it works when debugging is off

vagrant adder Jul 25, 2019, 4:29 PM

#

In your init.py file

#

Where are you pulling config from

#

Different file?

native tide Jul 25, 2019, 4:30 PM

#

yes

vagrant adder Jul 25, 2019, 4:30 PM

#

config.py?

native tide Jul 25, 2019, 4:30 PM

#

yes

vagrant adder Jul 25, 2019, 4:30 PM

#

Okay

#

Can you send code of it

native tide Jul 25, 2019, 4:31 PM

#

of my config.py?

#

import os
basedir = os.path.abspath(os.path.dirname(__file__))

class Config(object):
    SECRET_KEY = os.environ.get('SECRET_KEY') or 'you-will-never-guess'
    SQLALCHEMY_DATABASE_URI = os.environ.get('DATABASE_URL') or \
        'sqlite:///' + os.path.join(basedir, 'app.db')
    SQLALCHEMY_TRACK_MODIFICATIONS = False```

vagrant adder Jul 25, 2019, 4:33 PM

#

Under sqlalchemy_track_modifications put this line:
DEBUG = True

#

And if you need it off, change to False

native tide Jul 25, 2019, 4:33 PM

#

That didn't effect anything when I run flask

vagrant adder Jul 25, 2019, 4:34 PM

#

Is your script working fine?

native tide Jul 25, 2019, 4:34 PM

#

the program works absolutely fine when debug is off

#

it's a blog app, I can go through the different pages and login and out

vagrant adder Jul 25, 2019, 4:34 PM

#

Try running with debug off

native tide Jul 25, 2019, 4:34 PM

#

what I'm saying is setting that variable in the config didn't change anything

#

debug remained off

#

I can turn debug on from git using export FLASK_DEBUG=1

#

and turn it off setting it equal to zero

#

but I can't get the app to run when it's on

vagrant adder Jul 25, 2019, 4:35 PM

#

Okay, it isn't working through cli

#

Let's try it through code

If you really want to deal with env vars in powershell, head to #491524019825278977

native tide Jul 25, 2019, 4:36 PM

it doesn't work in Powershell or Git Bash

locally i can just do:

r.ping()

but REDIS_URL when using heroku is something like redis://h:839453h94h3fh@ec2-34-25-15-236.compute-1.amazonaws.com:16969

I have a little sortable list made with jQuery UI.
How I can disable the auto resize of the window when I drag a element of the list out of the borders?

native root Jul 26, 2019, 8:33 AM

#

The reason it's expanding is because the sortable ui moves the element according to position: absolute

#

when elements move outside their containers, and there's no other properties specified, css's overflow property defaults to scroll

#

which causes the scrollbar to appear and the element to continue to expand

#

if you wish the content to be cut off, you can set overflow to hidden

#

Anyone here ever worked with DJango and Angular?

winter flint Jul 26, 2019, 1:06 PM

@vagrant adder just to update what I was asking about before: you can just use the env var if you use redis.from_url() instead of 'redis.Redis()'

vagrant adder Jul 26, 2019, 1:50 PM

#

So you need actual adress to ping a redis server?

Just looking for a bit of direction not a full blown answer as I assume this isn't a quick question.

I'd like to have a table on my website. This table will pull data from a database. When the database updates I'd like the website to update only the values that have changed in the database automatically. I'd like to do this as efficiently as possible, is python the way to go or is this a problem that will likely be solved by JS/JQuery/Ajax or something ?

How I can save the order of the list and read it with flask?

lime thicket Jul 27, 2019, 11:15 AM

#

@woven surge without reloading the page and having the templating engine handle the changes to the table you will need some sort of JavaScript to fetch updates from an API and then modify the dom

woven surge Jul 27, 2019, 11:20 AM

#

so the JS needs to keep checking if there has been an update

lime thicket Jul 27, 2019, 11:20 AM

#

@tough star you could grab the list of <li>s and post it back to flask via an endpoint. With jquery it could be something like $( "li" ).toArray() to gather the list in the order it is

woven surge Jul 27, 2019, 11:20 AM

#

or can JS listen and then when the DB updates it can send a signal

lime thicket Jul 27, 2019, 11:20 AM

#

Yes unless your okay with the whole page reloading, and if so you can just use the templating engine

woven surge Jul 27, 2019, 11:20 AM

#

that way it doesn't need to keep querying the DB

lime thicket Jul 27, 2019, 11:21 AM

#

JS can’t listen, you could do some sort of socket setup possibly with the database update triggering an event but that increase the complexity significantly

woven surge Jul 27, 2019, 11:21 AM

#

right

#

thanks very much @lime thicket

tough star Jul 27, 2019, 11:27 AM

#

@lime thicket Can I use a sort of ajax?

lime thicket Jul 27, 2019, 11:28 AM

#

Yeah to send the data back to flask you would likely do some sort of Ajax POST or PUT

tough star Jul 27, 2019, 11:41 AM

#

@lime thicket But I don't know how to do

lime thicket Jul 27, 2019, 11:44 AM

#

The jquery documentation has some nice examples if you scroll towards the bottom https://api.jquery.com/jquery.ajax/#jQuery-ajax-url-settings. Try to start small, get a simple post to work that prints some string on the server side, then try and post the list order, then post the list order and save it however you need to

#

The flask mega tutorial also covers Ajax in one of the later sections https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xiv-ajax

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving
• Keep your patience while we're helping you.

So I have a webapp with a frontend and a seperate backend with an api. Regerstering works fine but how could I start a user session with my api?

Like I have a user log in and the frontend sends the login info to the api

Then it starts a user session

How would I make that work in flask? Would I have to implament oauth and all that rigamaroll like how discord does it with it's api (bots, clients)

does anyone mind going over how to tie reactjs frontend to a flask backend on a high-level? i have a react repo with create-react-app but how can i connect that to flask that's running separately?

rigid laurel Jul 29, 2019, 8:35 PM

#

Generally you design the flask app as a rest api that communicates with json data. Then you call the flask endpoints using ajax requests in react. But the main thing is to design your flask side as a rest api which you can find a lot of resources online for

hushed burrow Jul 29, 2019, 8:40 PM

#

so i've been reading that's one way to do it. where the flask api is consumed by the react frontend. but is there also another way to do it where I can just run the flask app and have it serve up react without running a separate react instance?

rigid laurel Jul 29, 2019, 8:45 PM

#

You could have a single view that includes a script tag of your react app

#

On the same app that the react is consuming

#

You might need babel js or Web pack or something to compile to the pure js. I'm not 100%

jsut curious in django you do a createuser thing ot create a user but what if you extended from the user class and created ur own sorta user, is there any way to create a user from teh command line again after that?

frigid egret Jul 30, 2019, 8:31 AM

#

@zealous igloo Yes, if you make custom classes from django built in classes and your program is going to treat them as though they are built in classes.

zealous igloo Jul 30, 2019, 8:31 AM

#

oh okay so then i can createsuperuser and stuff and it would create that sorta user and would it change my token authentication process at all?

frigid egret Jul 30, 2019, 8:32 AM

#

I've actually just finished doing such thing on my training project, put phone field in place of username

#

It wouldn't if you do it correctly. What you have to do is go to library files, find the class that you need, copy-paste it into your models.py and make changes you want there.

#

Here's my example if that helps:

#

...how do I use code paste thing? Keep forgetting

#

📎 models.py

#

nvm, I'll just send you the file. What I did there is I copied library classes that I need and made my custom changes to them. So now django treats my custom classes as though they are library.

zealous igloo Jul 30, 2019, 9:29 AM

#

by the way i was kind of thinking about it and wanted to get ur opinion on if i really need to change the default user class. So like i have a program where the user can write a list of stories they have read and i was thinking i was supposed to extend the user model to include stories read but instead could i just use the default user model and on the front end it can request for the data of the user by sending a get request with it's primary key and the database just finds whatever info is associated with that primary key and sends it

idea

is there a way to have a folder with a bunch of markdown files.
And that folder is named like blog or smth
and so when you go to mywebsite.com/blog/subpage it displays the markdown file with the name subpage.md inside of the blog folder.
I think you could have some kind of python parser file but I am not sure.

Essentially I want to be able to create markdown files, directly into the folder, upload it, and boom, html page created.

#

Another functionality I would like to have is someway to extract variables stored inside of the markdown files, such as:
subpage.md:

[blogpage-name]: My Blogpage Name

I don't remember if that's how you create vars but point remains

background-position: 50% 0;

#

What does it do? It looks like it centers the background image

#

(It's CSS)

mint canyon Jul 31, 2019, 10:56 PM

#

50% is the middle, yeah

#

 background-position: center;

#

you could also use this, much cleaner

#

@ruby palm

ruby palm Jul 31, 2019, 10:57 PM

Oh ok

Thank you!!!

#

So it does the same thing as background-position: 50% 0?

proper hinge Jul 31, 2019, 11:11 PM

I don't think so

#

yours only centers the x axis

#

but raizo's would center both I believe

well background-position: center; would be 50%,50% i just figured

so well the middle of the screen

How would you generally go about logging incoming requests that may contain sensitive information such as passwords? I've been considering if it's worth encrypting the sensitive data just for this purpose, or if I should create a logging module that selectively filters sensitive data from the log entries or something.

balmy forge Aug 1, 2019, 7:51 AM

#

for me I just hash the password then send the hash away

#

storing password is storing hash instead of actual password

open forum Aug 1, 2019, 7:54 AM

#

That isn't going to work in my case, because I need to send the password on to one of multiple third-party APIs.

balmy forge Aug 1, 2019, 7:55 AM

#

I guess then the only way is to do a 2-way hash method to hash sensitive data

#

and only convert it back in case you need it, but that's just as good as logging the sensitive data itself

open forum Aug 1, 2019, 7:56 AM

#

I mean, I will have access to the plaintext password in the code in any case, it's just about protecting it from someone reading the log.

#

So I could selectively remove it from the log, which is the second option I thought of.

#

Just trying to get a second opinion. Maybe there are industry standards for this kind of thing.

#

I guess normally you would know the hashing scheme of the database storing the password.

#

So you could just hash it in the client.

balmy forge Aug 1, 2019, 7:58 AM

#

normally, yeah, hash instead to keep "evidence" which helps tremendously in debugging and tracing as well

@open forum Is it possible to use some form of federated login across the services? That would provide a more cerntralised setup at least (think Oauth and other possible options)

open forum Aug 1, 2019, 2:20 PM

#

@leaden vessel I have no control over the third party APIs, and the credentials passed around are those of end-users of our customers.

#

We are merely facilitating communication between our customers and these APIs.

#

@stray nexus I have no specific need to log passwords, I was just wondering whether it's better to strip the logs or to encrypt the sensitive data.

#

I guess it's generally better not to send any sensitive information in plain text, even if it is over https.

Though I can't think of any obvious way to exploit it.

just curious with django i had this sorta website idea and im kinda wondering if it even possible in django. so just in very brief summary i have a site sort of like a excel for tv shows it has columns like wha tyou would rate teh show, how much u liked it outta 10 etc so i have models for the table for each column

#

would it be possible to make it so each user can customize their tables by adding/deleting their own columns but then im assuming this would mean that for every single user that changes their table from teh default there would have to be a diff model for every single one.

#

is that doable in django?

unborn terrace Aug 4, 2019, 8:28 AM

#

@zealous igloo yes

candid basalt Aug 4, 2019, 8:29 AM

#

It is doable in django, although you what you are talking about is much more then django itself.

unborn terrace Aug 4, 2019, 8:29 AM

#

Is it doable in <ANY BACKEND WEB FRAMEWORK EVER> ?
Also yes

zealous igloo Aug 4, 2019, 8:29 AM

#

oh am i right that every user would have to have their own model for the table

candid basalt Aug 4, 2019, 8:29 AM

#

Depends on what you are referring to as 'model'.

zealous igloo Aug 4, 2019, 8:29 AM

#

im just trying to conecptualize how i would do this, having a really hard time planning it out

#

u know like model with the datefields integerfields charfields etc

candid basalt Aug 4, 2019, 8:30 AM

#

In that case - probably no. All users will have a single table/model, but there will be a field in it specifying which user each record belongs to.

unborn terrace Aug 4, 2019, 8:30 AM

#

@zealous igloo well, the “user-defined models“ would not be Django models in that case, they will probably have their own representation, this is usually done using NoSQL data storage

candid basalt Aug 4, 2019, 8:31 AM

#

Django ORM is supposed to be used with relational databases.

zealous igloo Aug 4, 2019, 8:31 AM

#

would i have to use a non relational/NoSQL thing database?

unborn terrace Aug 4, 2019, 8:31 AM

#

@candid basalt well, there is PostgreSQL's JSONField allowing to do some cool schemaless stuff when needed

candid basalt Aug 4, 2019, 8:32 AM

#

There is, but it also produces a lot of issues. =]

unborn terrace Aug 4, 2019, 8:32 AM

#

@zealous igloo as you wish

#

@candid basalt well, issues would happen too using other databases 🤔

candid basalt Aug 4, 2019, 8:32 AM

#

@zealous igloo everything depends on what you want. It's possible to do with either relational or document-based or any other database of your choice. Each approach has it's own pros and cons.

zealous igloo Aug 4, 2019, 8:33 AM

#

i see wait so hwo could i do this without giving a table a model?

candid basalt Aug 4, 2019, 8:34 AM

#

@unborn terrace depends on the use case. When you work with the data structure that needs to be consistent and maintain it's integrity - most of the time you will want relational DB. When you want a lot of horizontal scaling - nosql may be a better choice.

unborn terrace Aug 4, 2019, 8:35 AM

#

@candid basalt sure, but it does seem appropriate here, where users should benefit from a kind of custom-defined database

#

Well, the app may also use “real” databases to represent them, but this involves so much more work than most apps of that kind store these user-define DBs in NoSQL storage

candid basalt Aug 4, 2019, 8:37 AM

#

Yes, that's true. NoSQL DBs tend to be better for prototyping.

#

Yet Django has a lot of stuff automated for you, such as schema generation and migrations, to name a few.

#

@zealous igloo if you want to use Django ORM - you will have to design your data structure around the relational DB paradigm and will have to use Django models. If you want to use something else like MongoDB or similar tech - it may make sense to use it directly instead without involving Django ORM.

unborn terrace Aug 4, 2019, 8:38 AM

#

Sure but these are not made for user-defined databases, they are for the app developer

zealous igloo Aug 4, 2019, 8:39 AM

#

oh okaya nd if i do use DJango ORM would i create a new Model for every singel user who wishes to have a differnet table?

#

if i useed a nosql database would mongodb be best choice for that?

unborn terrace Aug 4, 2019, 8:40 AM

#

do use DJango ORM would i create a new Model for every singel user who wishes to have a differnet table
@zealous igloo no, that's what I am just saying

zealous igloo Aug 4, 2019, 8:41 AM

#

i see it just @candid basalt said i would have to use DJango Models i just don't get how i would have ot use it and not have to create a new model for every single user

#

i saw your solution about how they would have a unique datbase representation but taht is just for nosql

unborn terrace Aug 4, 2019, 8:42 AM

#

That's the thing, these apps usually implement their own kind of “ORM” to manage that

zealous igloo Aug 4, 2019, 8:42 AM

#

oh so it might be more of a hassle to use djangos?

unborn terrace Aug 4, 2019, 8:42 AM

#

Very usually leveraging flexible schema-less datastores

#

No more than something else

zealous igloo Aug 4, 2019, 8:44 AM

#

i see it jsut so how would i use Django models for this?

candid basalt Aug 4, 2019, 8:45 AM

#

There are few ways to handle this:

Make a predefined set of additioanl fields users can choose from. This way you can still get away with clean RDB structure.
Make use of JSONField to store custom user columns (may have issues later down the road with querying them).
Use non-relational DBs such as MongoDB to store all your data (may have issues with attaching that with regular Django user management etc, which generally wants RDS under the hood).
Not use Django at all and go with flask+mongodb+something else (will loose Django's "batteries included" functionality).

unborn terrace Aug 4, 2019, 8:45 AM

#

You don't, your Django models will be used to model your application entities, not for the users to define them themselves

candid basalt Aug 4, 2019, 8:46 AM

#

If I were to do this - I'd try JSONField approach first. It seems the most convenient and less intrusive if you want to keep using Django/PostgreSQL.

unborn terrace Aug 4, 2019, 8:46 AM

#

^

zealous igloo Aug 4, 2019, 8:47 AM

oh wow okay thanks for the option idk whta jsonfield is atm but i'll look into it rn and i'll keep those other ways in mind for sure

@balmy forge The test results on sanic

#

Workers are 2

#

Threaded = True

#

Flask gives same result when used with nginx

balmy forge Aug 5, 2019, 1:02 PM

#

Ye sanic is pretty fast

#

Tornado is great too

It's hard to setup I guess

#

Documentation not that good

Hi all

#

Can someone help me figure something please?

#

I'm working on a practice website on Django.

#

It has users and also orders.

#

There is a User profile page and I'd like to have a list of orders made by that user on that page, next to basic user information.

#

Can't find a proper example or tutorial as this seems to be a somewhat non-standard task.

dusky bough Aug 5, 2019, 3:45 PM

#

How are your Users and Orders currently connected?

#

If you have a User page, you have the ability to query your Orders based on the User who's page you are on.

frigid egret Aug 5, 2019, 4:25 PM

#

@dusky bough Order object has a ForeignKey to User. But the way I'd like to filter them (and that is how I filter them on Admin site) is by "phone" field. Both User and Order have that field so it's easy to filter orders.

#

Basically, what I'm trying to do is to make a list of filtered Order objects on a User page being filtered by "phone" field.

@gleaming herald I put the tracking code as said and nothing changed in Real-time Overview

#

I've also disabled my Block tracking add-ons to be easy to be tracked but still

When I'm trying to deploy my python flask on apache server, on the local host page it just shows a directory of all my files and not the pages itself

late gale Aug 5, 2019, 8:56 PM

#

What is the hosting service that you use ?

#

@dense salmon

#

The best hosting service for python is pythonanywhere so i recommend to host your website there

dense salmon Aug 5, 2019, 9:04 PM

#

I was using Apache

#

This is for an intern thing, they said I should only use apache and not pythonanywhere.

#

so with django rest mixins i get that there are things like Create Update whatever that are triggered by certain HTTP requests. What request triggers the RetrieveModelMixin?

proper hinge Aug 5, 2019, 11:50 PM

#

A GET

Here is a handy table https://www.django-rest-framework.org/api-guide/routers/#simplerouter

Does anyone know if flask does any crsf stuff by default? I think its messing up one of my projects but Im not sure.

dense salmon Aug 6, 2019, 1:19 PM

#

Is anyone familiar with Apache24 And flask?
