That would be the cleanest way

#

Either you write it in an html and import it from the template, or in your base html, or you can register a python function if you're feeling brave

#

Basically write a macro with two parameters, one is your classes and one is the form field object. Then you write your html and inside the label tag {{ field }}. Bam, you have a reusable thing that does what you need

#

(I'll be really sorry though if there is a way to nest "expressions" the way you wanted. But I doubt it)

Can somebody help me figure out how to get AOS(animate on scroll) working with my flask application?
I followed it's documentation, and looked on stack overflow, and can't find out how to make it work. I tried importing how the docs say, I verified jquery is working, but I can't figure out how/where I'm supposed to AOS.init() because AOS is always undefined
Also verified that flask is seeing my aos.js

Hey guys, quick question about Django. I'm making an app for a school and I'm wondering about how to deal with different types of users

#

Current I've got models for teachers and for students (which have a foreign key relationship to the generic user model)

#

But I'm wondering if I should just use different groups for both

meager anchor Jul 19, 2018, 9:08 PM

#

Models with foreign keys to the settings.AUTH_USER_MODEL are generally the way to go about this, as far as I'm aware

#

What do you mean with "different groups", though?

#

If you want to deal with permissions, you probably want to create Teacher and Student groups through a data migration

fickle chasm Jul 19, 2018, 9:10 PM

#

Yeah it'd be with permissions, but also the teacher and student models have relations to other models (e. g. Assignments, classes, etc)

#

By groups I mean the option to create groups through the Django admin

#

So with AUTH_USER_MODEL, would I create the two different models (teacher and student) and add both to settings?

#

I'd like it to have 3 tiers of permissions, admin > teacher > student

#

(sorry, still pretty new to this)

meager anchor Jul 19, 2018, 9:19 PM

#

if the idea behind the custom models is purely permissions and you don't want to have any custom fields based on hierarchy, then you'd only use groups - but if as you said they have relations to other models, then having custom models is obviously the way to go. As for teacher and student permission hierarchy, groups would be the correct way to do it, but since you already have the student and teacher models, I'm not sure if it would be necessary - i'd use groups regardless since they integrate with django's permission system. You can use a signal or override save() in the teacher and student model to automatically add the student or teacher to the respective group on creation

#

For admins, I don't think you need a custom group, but it depends on what you mean by "admin". If that means logging in to the django admin, use User.is_staff: https://docs.djangoproject.com/en/2.0/ref/contrib/auth/#django.contrib.auth.models.User.is_staff

#

you can then give that user the appropriate permissions on the admin page

fickle chasm Jul 19, 2018, 9:22 PM

#

I could set it to all users that are teachers right? Or would I have to go through and select each individual user

meager anchor Jul 19, 2018, 9:22 PM

#

What might be worth noting is that Django 2.1 will add a view_x permission in addition to the regular add_x, change_x and delete_x permissions, but I think it still doesn't support object-level permissions (such as teacher x can edit course z but not course y), for that you might want to look into guardian: https://github.com/django-guardian/django-guardian

GitHub

django-guardian/django-guardian

django-guardian - Per object permissions for Django

#

You can just add it on creation time

fickle chasm Jul 19, 2018, 9:22 PM

#

Ah OK cool

meager anchor Jul 19, 2018, 9:23 PM

#

you can check out this code I wrote for a more involved example using signals: https://github.com/strinking/site/blob/master/home/signals.py#L12

#

also, to (sorry, still pretty new to this), don't worry about it, Django is quite the huge framework and it takes some time to get into

hmm can i somehow do a form that shows more options depending on what checkboxes are checked

#

on flask and wtforms

#

and bootstrap

meager anchor Jul 19, 2018, 10:43 PM

#

generally, questions about "can i" can generally be answered with "computers can do anything if you work at it hard enough", and i really like referencing that

#

dynamically displaying form fields is probably the easier part, but I would assume that complicates validation a bit

hearty birch Jul 19, 2018, 11:09 PM

#

its written in flask and the forms by flask-wtforms, and it seems like it's not passing the validation phase of UpdateAccountForm

#

no errors or anything

#

just doesn't update

#

the relevant files are routes.py and forms.py

Hello! I have a question to Django Masters :D. So i have my Book/Authors Wiki web app and in my Book model i have a CHOICES. It is a book types there (Historical, Drama, Horror etc). And i need to have another view, book_type_list view and there a list of my choices. But i don't know how to display all choices from my model. Anyone know how to do it? Sorry for my english 😐

queen needle Jul 20, 2018, 11:54 AM

It's been a couple years since I touched Django, but for starters what does your Book model look like?

#

😄

#

Okay good 😄

queen needle Jul 20, 2018, 11:57 AM

#

Lol

#

So you want to access those from your template?

native tide Jul 20, 2018, 11:58 AM

#

I create a new template (book_types_list) and i would like to have there all values from book_types

#

but i don't know how to create a view like this to display all types

queen needle Jul 20, 2018, 11:59 AM

#

You can pass Book.CHOICES (as a class attribute) as a parameter to your render template function

#

From inside the template you should be able to access it

#

I'm not on my pc so I can't check my old Django project right now but I remember it was similar to flask 😅

native tide Jul 20, 2018, 12:02 PM

#

Okay, so i read a documentation and i read something about get_FOO _display method

#

i create a view like this

#

https://pastebin.com/4e7p5cqa

queen needle Jul 20, 2018, 12:05 PM

#

Ah I remember now, the context

#

Which call is throwing this error?

native tide Jul 20, 2018, 12:06 PM

#

It is a book_types = Book.get_book_types_display()

queen needle Jul 20, 2018, 12:08 PM

#

Lemme check the docs

native tide Jul 20, 2018, 12:10 PM

#

Okay

queen needle Jul 20, 2018, 12:10 PM

#

Based on the docs

#

It should be get_BOOK_TYPES_display

#

Watch the case

#

I don't know if case is relevant for that function implementation tho

native tide Jul 20, 2018, 12:12 PM

#

I try to take a BOOK_TYPES but then i have another error - type object 'Book' has no attribute 'get_BOOK_TYPES_display'

#

;<

queen needle Jul 20, 2018, 12:12 PM

#

Nvm it's not. But also this isn't the function you want, I believe

#

You want to retrieve the entire content of BOOK_CHOICES right?

native tide Jul 20, 2018, 12:13 PM

#

Yes

queen needle Jul 20, 2018, 12:13 PM

#

In the context, pass Book.BOOK_TYPES

#

The _display function does something different, it gives you the "long name" for the choice of the current record

native tide Jul 20, 2018, 12:15 PM

#

Okay so at the first

#

Delete book_types value from my view

#

and just add a Book.BOOK_CHOICES':Book.BOOK_CHOICES to my context

#

?

#

('Book.BOOK_CHOICES':Book.BOOK_CHOICES)

queen needle Jul 20, 2018, 12:16 PM

#

Sorry it's book types, I forgot what's it called in your module

#

Just pass {"book_types": Book.BOOK_TYPES} as context to the render function

#

Then inside the template you can access the collection by referring to book_types

native tide Jul 20, 2018, 12:18 PM

#

So i have a bug

#

type object 'Book' has no attribute 'BOOK_TYPES'

queen needle Jul 20, 2018, 12:19 PM

#

Lol omg I'm sorry, I got the names mixed up...

#

It was BOOK_CHOICES

pearl kite Jul 20, 2018, 12:20 PM

It's Book.the_same_damn_attribute_in_your_class_definition 😂

No problem, everything work so very good 😄

queen needle Jul 20, 2018, 12:29 PM

#

tl;dr the function you were using didn't do what you thought it did 😜
Dunno if there's any other helper to get the choices, but passing the class attribute is simple enough.

native tide Jul 20, 2018, 12:30 PM

Its nicer than flask because it has a bunch of stuff already attached to it

so for stuff you can do like from django import login (but the actual name of it i cant remember) and boom you got authentication

(someone correct me if i'm wrong but thats my understanding)

flask is also mean to be a 'micro-framework', ie one with very few dependencies

for most things, you'll need to install a lot of third party packages and such

"a lot" is an over exaggeration

ask

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.

You can find a much more detailed explanation on our website.

well, assuming it's running, the firewall isn't blocking it, and you're connecting to the right host, it should work.

You should secure your SSH server with either a really strong password, fail2ban, or disabling password logins and using SSH keys

quartz maple Jul 24, 2018, 8:17 AM

#

it has a strong password

wicked mason Jul 24, 2018, 8:17 AM

#

I highly recommend fail2ban

brave mantle Jul 24, 2018, 8:17 AM

#

Yeah, it's very useful

#

It basically blocks IPs in the firewall for a while if they get the password wrong too many times

wicked mason Jul 24, 2018, 8:18 AM

#

even on my private vps which only hosts a discord bot, fail2ban bans 100s of ips daily

brave mantle Jul 24, 2018, 8:18 AM

#

Yeah, there's always someone trying your ports

#

That's the Internet for you

wicked mason Jul 24, 2018, 8:18 AM

90% of ips getting banned are chinese

#

alright time to ask my css question

#

I have the following div (eu cookie notice):

📎 unknown.png

brave mantle Jul 24, 2018, 8:20 AM

#

I think I know what you're gonna ask

#

The footer, right?

wicked mason Jul 24, 2018, 8:20 AM

#

I want the image on the left to be 100% of the div's size

#

wrong 😉

brave mantle Jul 24, 2018, 8:21 AM

#

So set the width to 100%?

#

That'd look terrible though

wicked mason Jul 24, 2018, 8:21 AM

#

yea I want there to be no empty space

#

when I set the padding (or margin) to 0, the div shrinks

brave mantle Jul 24, 2018, 8:21 AM

#

There's probably a margin on the div

#

Or on the image

wicked mason Jul 24, 2018, 8:22 AM

#

setting margin & padding on the image tag does nothing

#

this is what happens when I set the margin to 0 on the div

📎 unknown.png

brave mantle Jul 24, 2018, 8:23 AM

#

Isn't that what you wanted?

wicked mason Jul 24, 2018, 8:23 AM

#

nah, the div shrunk

brave mantle Jul 24, 2018, 8:24 AM

#

You could set a min-height on the div then

#

or set padding on another element inside the div

wicked mason Jul 24, 2018, 8:25 AM

#

alright...

#

📎 unknown.png

#

any idea on how to vertically center the text & button now?

quartz maple Jul 24, 2018, 8:25 AM

#

@brave mantle ey bro

brave mantle Jul 24, 2018, 8:25 AM

#

You'd probably be better off applying the padding to a div containing the text/button

#

rather than setting a min-height

alright

How can I make online multiplayer

Any help please

strange thorn Jul 26, 2018, 4:13 PM

#

are you referring to online multiplayer for browser games or for desktop apps?

native tide Jul 26, 2018, 4:13 PM

#

Desktop

strange thorn Jul 26, 2018, 4:14 PM

#

usually you would write the client side aka the desktop app in a language actually suited to gaming

#

like c++ c# etc

#

and if you are using a prebuild engine, which you would usually do it is extremly likely this engine already has support for the server side built in

#

so you would write the server side in that lang too

native tide Jul 26, 2018, 4:15 PM

#

But I have to use Python

#

How can I do it with Python

strange thorn Jul 26, 2018, 4:15 PM

#

the same way you would do it with any lang

#

how can you do it is such a general question

native tide Jul 26, 2018, 4:15 PM

#

And how is thst

#

That

#

Like

strange thorn Jul 26, 2018, 4:15 PM

#

that hihgly depends on what you are doing

#

there is not one general way

native tide Jul 26, 2018, 4:15 PM

#

It's a 3d game where there's boxes on a flat plane

#

If someone starts it creates a new box for them they can control

#

And it's online multiplayer like that so they can see each other controlling the boxes

strange thorn Jul 26, 2018, 4:16 PM

#

if you dont want to fight with the pain of plain sockets (trust me you dont) you'd use the twisted framework for python

#

supports both server and client side

brave mantle Jul 26, 2018, 4:17 PM

#

No you wouldn't

#

You'd use asyncio lol

strange thorn Jul 26, 2018, 4:17 PM

#

twisted has async support

brave mantle Jul 26, 2018, 4:17 PM

#

There's no advantage to using twisted though

strange thorn Jul 26, 2018, 4:17 PM

#

ive seen twisted listed as a requirement for some backend jobs in game dev

#

¯_(ツ)_/¯

brave mantle Jul 26, 2018, 4:17 PM

#

In fact twisted is considerably slower than asyncio

#

Python 2 jobs, maybe

native tide Jul 26, 2018, 4:18 PM

#

Soo

#

I don't use twisted??

strange thorn Jul 26, 2018, 4:18 PM

#

so you would use some sort of async framework

#

your decision i guess

#

anyway once youve picked your framework

#

you would have to build some sort of synchronization mechanism

#

so the server always contains the state of a game and the clients can read from it and can write to it

#

although i am not sure how to exactly implement that one

native tide Jul 26, 2018, 4:39 PM

Huh

strange thorn Jul 26, 2018, 4:57 PM

#

what huh

#

i wont think of a system just for you in detail, youll have to serialize your objects representing your game entities or the client unique information of those objects into some sort of string with pickle for example

#

and then send them to the server

brave mantle Jul 26, 2018, 5:01 PM

#

Except not pickle, pickle isn't safe

@cobalt valve

#

can u help me with socket?

polar wasp Jul 27, 2018, 6:16 AM

#

@cobalt valve your "while 1" is going to make it try to start hundreds of threads that won't be able to get the socket, and it seems like the threads never get a chance to run because the main thread is holding the GIL. Consider using the threading module and its join method instead. Also, your thread functions can't be generators (no yield statement), what are you trying to do with that? I'm on my way to bed, but I can maybe help you tomorrow

lavish prismBOT Jul 27, 2018, 6:16 AM

ask

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.

You can find a much more detailed explanation on our website.

@quartz maple I think we've talked to you about your attitude a couple times now, but that's simply not how you treat people you want help from.

By not actually posting your question, you're just wasting everyone else's time instead. If you're so intent on getting an answer, ask the actual question. And remember to provide a code example and information on what you've done to solve your problem.

#

Nobody is going to go "Yes I can sockets" and wait a few hours for you to post your question.

Hello, I was wondering if someone could help me

#

I cant seem to find an element on a website that I want to use in selenium

#

And when I go into the chrome element finder, nothing appears

#

Does this have anything to do with it having to use adobe flash player

polar wasp Jul 27, 2018, 3:22 PM

#

probably

#

flash is flash, as far as HTML is concerned it's just a single media element without anything in particular inside it

wind tangle Jul 27, 2018, 3:23 PM

So selenium isnt an option then?

apparently there is a flash selenium https://code.google.com/archive/p/flash-selenium/

Hello, I'm having a issue with flask and dynamic forms, can someone help me?

#

I created a subclass of a form inside a view. I have to grab information online via json, and then display the forms using the name/ID that the json file gives me. I'm looping through json and appending to a list StringFields('id'). This creates a bunch of UnboundFields. So far so good, but I cant display them using Jinja. If i just loop through the list and call the field, it display something like <UnboundField(StringField, ('SKU : ',), {})>... If I use form.label() it gives me an error: UndefinedError: 'wtforms.fields.core.UnboundField object' has no attribute 'label'.

hey guys, i wrote a custom script in flask for the page I want to refresh. It works fine on the same browser but doesn't work across browsers, does any one know why?


<script>

  window.setInterval(function(){
      if(localStorage.update == "1"){
          localStorage.update = "0";
          window.location.reload(true);
      }
  }, 100);
</script>

{% endblock %}

#

So this is the page that is being refresh, it is activated when I press a button on the other page.

#

Updating the page to get an update of the database table basically.

#

Does this has anything to do with cookies? I don't think so as I inspect the source code and it simply jquery to me, unrelated to cookies. I checked the console, no errors and it works on the same browser, just not across different browsers; it doesn't refresh.

#

maybe the refresh command is the problem, does anyone know any alternative function to that's able to refresh across all different browsers?

#

Update: I just tried incognito mode and it appears to be the case for chrome, that this is related to sessions and cookies perhaps. guessing it has to do with local storage.

Anyone know this error, getting sqlalchemy_utils.exceptions.ImproperlyConfigured: ‘cryptography’ is required to use EncryptedType using flask and sqlalchemy

meager anchor Jul 30, 2018, 10:36 AM

#

a blind guess would be that you need to install the cryptography package with pip?

#

https://sqlalchemy-utils.readthedocs.io/en/latest/data_types.html#module-sqlalchemy_utils.types.encrypted.encrypted_type

#

EncryptedType needs Cryptography library in order to work. yup

Is it possible in Django to add a form for a different (related) object under a detailview?

#

I've got a school group detailview that I'd like to have a form under to add an assignment to the group

Would I just use a form mixin?

@native tide what is your problem

native tide Jul 30, 2018, 8:43 PM

#

@grand badge I Fix it yesterday, but thanks for asking :D

#

this is my code for the login form

def login():
    """Log user in"""

    # Forget any user_id
    session.clear()

    # User reached route via POST (as by submitting a form via POST)
    if request.method == "POST":

        # Ensure username was submitted
        if not request.form.get("username"):
            return apology("must provide username", 403)

        # Ensure password was submitted
        elif not request.form.get("password"):
            return apology("must provide password", 403)

        # Query database for username
        rows = db.execute("SELECT * FROM users WHERE username = :username",
                          username=request.form.get("username"))

        # Ensure username exists and password is correct
        if len(rows) != 1 or not check_password_hash(rows[0]["hash"], request.form.get("password")):
            return apology("invalid username and/or password", 403)

        # Remember which user has logged in
        session["user_id"] = rows[0]["id"]

        # Redirect user to home page
        return redirect("/")

    # User reached route via GET (as by clicking a link or via redirect)
    else:
        return render_template("login.html")```
 Whenever I enter invalid user/pass combo I am getting this error: TypeError: get_bind() got an unexpected keyword argument 'username'. instead of returning the invalid user/pass 403 page
any ideas why?
no issues when typing just username or just password. only getting error when typing in both

Hey its possible to use a string as a variable in Jinja? For example if I create a new dynamic field with setattr like, setattr(BaseForm, 'id', StringField('name'), this ID at the moment is unknown to me, because it comes from another server. I need to render it but the only way I can know the ids is if I pass a list of IDs to the template, and loop through it to find each ID. What I tried and failed is to loop in the template and use the ids like: form.ID().

#

if this makes sense

#

{% for id in list_of_ids %}
{{ form.id.label() }}
{{ form.id() }}{% endfor %}

#

list_of_ids is a list of strings

@shrewd sand Only just to see difference :d

grand badge Jul 31, 2018, 11:22 PM

#

@native tide you can't really say one framework is worse than another framework. Flask and Django can make you the same end product. I guess its based on preference

#

Django is a batteries included framework while flask makes you choose the batteries you want with your project

tame viper Jul 31, 2018, 11:24 PM

you can even mix and match. duracell + panasonic if you want.

I'm having issues with Sockets and what content I am supposed to put in a .sock file. I'm not sure what it means in the tutorial i'm following by We will tell it to start 3 worker processes (adjust this as necessary). We will also tell it to create and bind to a Unix socket file within our project directory called myproject.sock. We'll set a umask value of 007 so that the socket file is created giving access to the owner and group, while restricting other access. Finally, we need to pass in the WSGI entry point file name and the Python callable within:.

#

``[Unit]
Description=Gunicorn instance to serve myproject
After=network.target

[Service]
User=sammy
Group=www-data
WorkingDirectory=/home/sammy/myproject

ExecStart=/home/sammy/myproject/myprojectenv/bin/gunicorn --workers 3 --bind unix:myproject.sock -m 007 wsgi:app
I have setup my.service`` file.

#

However, it seems this bit: ExecStart=/home/sammy/myproject/myprojectenv/bin/gunicorn --workers 3 --bind is what is causing errors.

neat nest Aug 1, 2018, 12:19 AM

#

had the error changed since the last time you provided it in this channel? if not, Gdude and I still believe it to be an issue with your directory permissions. make sure it's accessible to the user running the process

#

you don't need to put anything in the sock file, as the tutorial says, it will be created for you

quartz maple Aug 1, 2018, 12:19 AM

#

okay well if it is

#

then, whats the command to change that?

#

the user is inteca-webmaster

#

and it was created for this

#

i didn;t realise i was supposed to use a non-root user

#

otherwise i would just use root

#

til i got evverything setup properly

#

no the error hasnt changed. but im restating my issue as i got in trouble for nt pproviding enough info

#

so there you go..

neat nest Aug 1, 2018, 12:22 AM

chmod and chown are standard permission manipulation commands, I would look into them

seems like a weird time to ask for help with it if you're not using it

#

I dunno why everyone think Flask is easier for beginners, it seems like Django is to me

#

Django might seem more complex because it has more "stuff" packed in it, but without some solid class design, project management and understanding what extensions you need, you won't get very far in Flask - whereas with Django you can get a site up and running quickly and even takes care of the DB for ya

neat nest Aug 1, 2018, 8:23 AM

#

I think the notion that it's easier lies in the fact that you can produce your first barebones web service in minutes, not that it can achieve the same level of baseline functionality with minimal effort

#

Django is certainly much easier in the sense that it handles lots of work and design for you in stages of development beyond the very earliest

grand badge Aug 1, 2018, 8:59 AM

#

I think people don't recommend django to beginners is that a lot of things can be confusing at first. Flask is a bit more easy to understand. I started out with Flask and liked it but because of the many choices of databases and other stuff, I started learning django.

queen needle Aug 1, 2018, 9:46 AM

#

yes, the main difference lies not in the difficulty of the framework but in the approach

#

that's why I think django and flask are not competing, but complementary

#

Django seems more suited for the top-down approach, while Flask is made for the bottom up strategy

in Django how to change permissions for a model with a OneToOne relationship to a User model?

#

currently I've got this -

#

`class Teacher(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)

class Meta:
    permissions = (
        ('create_assignment', "Create an Assignment object"),
        ('change_assignment', "Update an Assignment object"),
        ('delete_assignment', "Delete an Assignment object")
    )`

#

views.py class AssignmentCreateView(PermissionRequiredMixin, CreateView): permission_required = ('create_assignment', 'change_assignment', 'delete_assignment') model = Assignment form_class = NewAssignmentForm

#

i'm not sure if I should change Teacher to an AbstractUser or if there's a different way of going about it

#

i've already run manage.py migrate so the permission are in the db

#

I'd like it so that only users with a related teacher model can create assignment objects

ask

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.

You can find a much more detailed explanation on our website.

I am guessing this is what I have to do. but not sure

This is existing code on my purchase.html

#

{% if facebook_pixel_id %}
    <script>
        fbq('track', 'Purchase');
    </script>
{% endif %}

#

Should I paste my facebook-pixel.py also ?

#

hello?

Is there a way to block someone from being able to see a flask url when it is only meant to be pulled by the javascript in the frontend, the information passed is meant to be hidden within the game, but I'm not sure how I would render the image from the data in the backend without another player to be able to simply pull that information by typing a url

neat nest Aug 3, 2018, 2:43 AM

#

you'd either need a mechanism to verify that the frontend is making the request or to encrypt the response

sour heath Aug 3, 2018, 2:43 AM

#

I believed so

neat nest Aug 3, 2018, 2:43 AM

#

in either case, due to JS's rather transparent nature, you're essentially just obfuscating

#

a determined enough user probably won't find it difficult to spoof or crack whatever mechanism you use

sour heath Aug 3, 2018, 2:44 AM

#

yea

#

welp

neat nest Aug 3, 2018, 2:45 AM

#

the only surefire way to make sure they don't get the data is to structure your application so that it's not sent, but you mentioned that seems impossible

sour heath Aug 3, 2018, 2:45 AM

#

well, to my knowledge

#

I'm not exactly the most experienced in this stuff

neat nest Aug 3, 2018, 2:46 AM

#

if you share some of your concept, maybe others could weigh in

sour heath Aug 3, 2018, 2:47 AM

#

my concept being what I'm doing?

neat nest Aug 3, 2018, 2:47 AM

#

sure, at least enough that you think people could help determine how you might limit the data offered to the end user

sour heath Aug 3, 2018, 2:47 AM

#

okay, I'll try, am I allowed to post an example of what I'm doing as a website?

#

or would that be classed as advertising?

neat nest Aug 3, 2018, 2:48 AM

#

should be fine

#

will be fine, I should say. I'm an admin giving you explicit permission

sour heath Aug 3, 2018, 2:49 AM

#

okay, minichotagames.ml should build your hand and if you after, happen to go to minichotagames.ml/image_movement/.card{x}

#

1 would correspond to player ones first card

#

up to 4 being all player ones cards

#

and 5-8 being player twos cards

#

this is obviously not good as its simple enough to access such data

neat nest Aug 3, 2018, 2:50 AM

#

ah, I see

#

so you don't need to provide both players with all the data pertaining to the other player, it just happens to be publicly accessible at the moment

sour heath Aug 3, 2018, 2:51 AM

#

what?

neat nest Aug 3, 2018, 2:51 AM

#

you made it sound like you needed the frontend to always be able to get everyone's information, but that doesn't seem like the case to me

sour heath Aug 3, 2018, 2:52 AM

#

really?

neat nest Aug 3, 2018, 2:52 AM

#

the server should be doing the work of managing the rules, not the client

sour heath Aug 3, 2018, 2:52 AM

#

did you also happen to test the basic functionality of the program to furthur prove your theory?

neat nest Aug 3, 2018, 2:52 AM

#

it's less of a theory and more of a recommendation

sour heath Aug 3, 2018, 2:52 AM

#

or is it such an issue on how my program is built

#

ah

neat nest Aug 3, 2018, 2:53 AM

#

is there a reason that client 1 always needs access to client 2's cards? or could the server determine at its discretion when to reveal that information?

sour heath Aug 3, 2018, 2:54 AM

#

truthfully, I'm not sure, I wouldn't think so

#

except when, during the playing phase of the game that exists between the two players that the other player would have to load the other players card as its played

#

in the actual game, their hands would be hidden

#

to each other till such an event occurs

neat nest Aug 3, 2018, 2:56 AM

#

so in that event, they should be making a request to the server to find out what card was played, assuming you're doing this entirely with HTTP endpoints

#

does that sound feasible?

sour heath Aug 3, 2018, 2:57 AM

#

well, I think so

#

by http endpoints you mean flask endpoints correct?

neat nest Aug 3, 2018, 2:57 AM

#

yup

sour heath Aug 3, 2018, 2:58 AM

#

something like this in the javascript $('#div3').replaceWith() would ruin such a thing though, yes?

#

as you can view in the webpage

neat nest Aug 3, 2018, 2:59 AM

#

oh, is the card revealed when it's played or no? I admit I'm not testing your application at the moment because I'm on a phone and multitasking

sour heath Aug 3, 2018, 2:59 AM

#

well, as I haven't exactly made it multiplayer, it more or less moves it

#

but theoretically if they were hidden in the first place, they would be 'revealed'

#

as I have a sort of 'key'

#

keys = { 'card1': player1Choices[0], 'card2': player1Choices[1], 'card3': player1Choices[2], 'card4': player1Choices[3], 'card5': player2Choices[0], 'card6': player2Choices[1], 'card7': player2Choices[2], 'card8': player2Choices[3]}

#

this is what the flask endpoint is using to comprehend what card is pulled upon making a jquery ajax request

neat nest Aug 3, 2018, 3:03 AM

#

I'm afraid I don't follow

sour heath Aug 3, 2018, 3:04 AM

#

okay, above is something that updates a dictionary that the javascript uses

#

in this endpoint

#

def play(card): card = card.strip('.') Played.append(keys[card]) return str(keys[card])

#

the only important part is the return

#

also accessing this url happens to mess up the flow of the game as it appends to the 'Played' list

#

this is just making it so in the js I can type something like: python var card = $.ajax({ type: "GET", url: "/image_movement/.card1", async: false }).responseText;

#

and it will return player ones first card

neat nest Aug 3, 2018, 3:15 AM

#

this is more of a general comment on design, but it would also help mitigate some of your data hiding issues. my recommendation would be to have one /hand endpoint for this purpose, instead of an endpoint for every card. the clients would need to provide some token verifying which they were and then could recieve all the information they ought to at once

sour heath Aug 3, 2018, 3:16 AM

#

but doing so would change the difficulty of 'playing a card'

#

as I would have to find the index of the card, but I'll be fine, what kind of token do you speak of?

#

whenever the ajax request happens it inputs the token?

#

I believe this would work but if the player were to view the js file in the debugger window, they could easily access such a thing

neat nest Aug 3, 2018, 3:20 AM

#

sure but the player knowing their own token would only give them access to whatever information their client already has

sour heath Aug 3, 2018, 3:20 AM

#

I see

neat nest Aug 3, 2018, 3:20 AM

#

the token would be provided by the server to verify which client is which, you'd probably want to randomly generate them so they don't get reused

sour heath Aug 3, 2018, 3:20 AM

#

so the file for each player would be different

#

js file that is

neat nest Aug 3, 2018, 3:21 AM

#

hmm, I don't see why that would be the case

#

the server would make them aware of which player they are and that should be enough information

sour heath Aug 3, 2018, 3:21 AM

#

hm

#

this seems difficult

#

what if the player were to trace the vars and find the token to the other player?

neat nest Aug 3, 2018, 3:23 AM

#

why would they have access to the other player's token?

sour heath Aug 3, 2018, 3:23 AM

#

well, thats what I'm finding hard to prevent

neat nest Aug 3, 2018, 3:24 AM

#

there'd need to be an initial "handshake" where the server and client exchange information

#

that's when the client gets its token

#

although
