in CASCADE case, if parent element is deleted, then all its connected childs deleted too

#

PROTECT sounds like, parent element will not be able being deleted, until it is out of childs

desert estuary
#

anyone ?!

#

...

native tide
#

try placing the class definitions at the top?

jovial cloud
#

You need to import both Students and Admin as well as create the tables for those model classes

desert estuary
# 
>>> Students.query.all()
[Student:Students.id Students.fullname Students.dialling_num Students.branch]
``` i dont get the content inside those

actually it is in the database

and here's the app

#

see the same info

well i ahd this but it's kinda minor still bothers me when i first created the app i had been accessing all the modules or the files idk what to name them but i could access them easily with just for instance
i was typing

from models import student ...

now i always have to include

from Flaskiproject.models import students,admin ...

idk what changed
2) i still have the same problem of not accessing data from the db shell

jovial cloud
#

Regarding

  1. Check if the folder path you're running the commands from in your terminal has the same root as the 'models' module
  2. I just saw your previous code again, and noticed that you're calling the class attributes instead of the instance attributes
Admin.id should be changed to self.id and so on,
Same goes for Student.id and others```
desert estuary
#

also another thing i had the issue with is i couldn't render the whole table of the database

# 
return render_template("Admin/profiles.html",Students = Students.query.get(1),date=eleganter_date)
```  i do understand about the get()
but that's the only way it rendered data from the database
#

i couldn't render all the data in the database while doing Students.query.all()

I am trying to figure out why this purple space is there, and how to get rid of it>

#

The website only works on mobile right now, let me know if you know how to sort this

manic crane
#

when i do this does it delete the super user ?

dry obsidian
#

So I have a question, let's say I have a REST api backend. If the frontend and backend are hosted in the same host will there be a delay when I call the backend from the frontend?

#

Or does it depend on the internet connection

manic frost
dry obsidian
#

Wait so what will be faster?
1- Make a REST backend that will call an external Api and sort the data then return it

  • Call the external Api directly fromt the frontend then sort it
opaque rivet
#

@dry obsidian second option, but you might want the first option if you want to cache external API data and distribute it between users (resulting in less external API calls - which saves cost if its paid).

dry obsidian
#

But is there a big speed difference between the 2 options?

opaque rivet
#

The first option you're sending a request to your backend (and also to the external API), so it'll be slower by the amount of time to request your backend.

Not much, I'd say 200 ms more.

dry obsidian
#

Ok good to know thanks!

opaque rivet
#

I prefer to handle all API work on the backend, because it's easier to work with data using python than JS (opinionated) and it gives you the option to cache. Also if you request from the frontend, users can see the endpoint and abuse it. Routing it through your backend means you can rate limit each user.

dry obsidian
#

Ok I'll go with this option, it fits my project the best 👍

manic frost
#

@dry obsidian If the external API requires an API key, you can't go with the second option

dry obsidian
#

Oh true, didn't think about that cause I plan on using the YouTube API

Hello, Ive got some questions about Django apps within the framework that im hoping someone could better explain. I get the reason why you should create apps for user profiles and etc. but i am struggling to know when to create an app for something for a website.

#

help me tidy up this monstrosity please lol, this is probably the worst solution to the problem but my brain can't think of a better way to do this atm
all I want is to add the "active" functionality to bootstrap's navbar so that the buttons reflect what page you're on - it works but it's so embarrassingly janky lol

# 
<li class="nav-item">
    <a class="nav-link active" id="home" href="/">home</a>
</li>
<li class="nav-item">
    <a class="nav-link" href="/projects">projects</a>
</li>
<li class="nav-item">
    <a class="nav-link" href="/contact">contact</a>
</li>

{% if path != "" %}
<script>
    console.log('{{ path }}');
     $(document).ready(function () {
        $('a[id$="home"]').removeClass('active');
        $('a[href$="{{ path }}"]').addClass('active');
    });
</script>
{% endif %}
#

path is HttpRequest.path[:-1]

dire urchin
#

yeah okay sorry about the above mess, this should make more sense I think (?)

Here is the solution to the problem I was looking for for the search feature in django

from django.db.models import Q

class SearchContact(ListView):
    model = AdressEntery
    template_name = "main/search.html"
    context_object_name = "result"
    
    def get_queryset(self):
        query_input = self.request.GET.get('q')
        result_obj = AdressEntery.objects.filter(Q(name__icontains=query_input),active=True, user=self.request.user)
        return result_obj
    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        context['counter'] = self.get_queryset().count()
        return context

<form action="{% url 'search' %}" method="get">
  <input name="q" type="text" placeholder="Search...">

It's not really getting added but getting concatenated. How can I add?

or using a path converter

dawn shard

#

which is it framework btw?

#

I am highly sure that returning
return '''

is not acceptable

#

you should return some sort of Response class with body inside it

#

preferably in json format

dawn shard
#

It worked

inland oak
# 
def ed(num0, num1, num2):

None values serve nothing, perhaps to remove it

dawn shard
#

It can concatenate strings not int.

#

so i did this ```py
@app.route('/ed/<num0>/<num1>/<num2>')
def ed(num0=None, num1=None, num2=None):
total = int(num0) + int(num1) + int(num2)
Total = str(total)
return '''
Addition is ''' + Total

Hi there, I hit a wall with Django forms.

I made a contact form that posts an email and it works just fine. does what its supposed to.
However, when I try and include the same form in to my home page the post functionality just stops working

the contact_form.html is as follows...

    {% csrf_token %}
    {{form}}
    <button type="submit">Submit</button>
</form>```

and this works perfectly

but when I include this file in my home.html
# 
    {% load crispy_forms_tags %}
    <div class="container">
        <!-- Contact Section Heading-->
        <h2 class="page-section-heading text-center text-uppercase text-secondary mb-0">Contact Me</h2>
        <!-- Icon Divider-->
        <div class="divider-custom">
            <div class="divider-custom-line"></div>
            <div class="divider-custom-icon"><i class="fas fa-star"></i></div>
            <div class="divider-custom-line"></div>
        </div>
        <!-- Contact Section Form-->
        <div class="row justify-content-center">
            <div class="col-lg-8 col-xl-7">
                {% include 'contact/contact_form.html' %}
            </div>
        </div>
    </div>
</section>```

it does not work
versed python
#

Oh wait you already have them

#

What exactly isn't working?

#

Is the request not being sent?

stable sentinel
#

correct, when posting from home.html it does not post

#

but it does from contact_form.html

#

my forms.py is as follows


    name = forms.CharField(max_length=50)
    email = forms.EmailField()
    inquiry = forms.CharField(max_length=150)
    message = forms.CharField(widget=forms.Textarea)

    def get_info(self):
        """Method returning a formatted string
        :return: subject, message
        """
        clean_data = super().clean()

        name = clean_data.get('name').strip()
        from_email = clean_data.get('email')
        subject = clean_data.get('inquiry')

        msg = f'{name} with email {from_email} said: '
        msg += f'\n{subject} \n\n'
        msg += clean_data.get('message')

        return subject, msg


    def send(self):

        subject, msg = self.get_info()

        send_mail(
            subject = subject,
            message = msg,
            from_email = settings.EMAIL_HOST_USER,
            recipient_list = [settings.RECIPIENT_ADDRESS]
        )

contact/views.py is

from .forms import ContactForm
from django.urls import reverse_lazy

class ContactView(FormView):
    template_name = 'contact/contact_form.html'
    form_class = ContactForm
    success_url = reverse_lazy('contact:success')

    def form_valid(self, form):
        """
            call the custom method of our ContactForm class
        """
        form.send()
        return super().form_valid(form)

class ContactSuccessView(TemplateView):
    template_name = 'contact/success.html'

this is whats rendered in contact_form.html

#

and I am almost sure that I am importing this the wrong way in my home/views.py the wrong way

from contact.forms import ContactForm


def home(request):  
    """"""
    form = ContactForm(request.POST)
    projects = Project.objects.all()
    context = {
        'projects': projects,
        'form': form,
    }
    return render(request, 'home/home.html', context)```
#

the projects render just fine and the view of the form but it does not post

I found what the my problem was!!
In my home/view.py I am using a TemplateView to render the page,
the TemplateViews need an explicit POST method which I did not have!!!
I had this declared in my contact form/views.py and implied it in my home/views.py.
(boy was this a lesson to remember!!! 😅 )

BTW I would not call what I did in my forms.py as logic, the get_info() method is simply just cleaning up the data. This is something I came across in the docs. Passing in there the send_mail() function from django.core just made me think at the time of writing that it will allow me to keep my views.py a bit more straight forward 🤷‍♂️

As I am new to Django and development in general, is this somehtig that one would label as not the best practice? Or is this a subjective thing at this point?

P.S.

Thanks for answering me, it was a massive help in finding my answer!!

# native tide I don't really have any ideas for what to put on my portfolio page though. I do...

Yeah, I feel your struggle... I have been/am struggling with getting good ideas and I have just lately understood how to go about this.

The approach that I am taking is that I do the usual projects found on Medium articles and youtube. Such as a task manager(to do list), blog, photo album etc... These give you good insight on user registration/authentication CRUD functionality, working with REST APIs and the list goes on...
Once you start seeing what you build and how to build it, you will start some ideas of your own...

The struggle is real, I know but you just have to start and pull through the first couple of tutorials. Check out realpython articles on django, there's a good one for a project portfolio. Build that up and hook it up with a free bootstrap template (that's what I'm doing right now) it will be an amazing learning experience!

Just don't rush your self, take it easy and consider the small apps as a project and sooner than you think those projects will turn in to apps of a bigger project.

Hi,
I'm building an Blog App using Django and just added the comment functionality on my Posts.
An HTML page will display a Post and all the comments below it. Also, it will display a form to submit a comment on that Post.
Previously, I was fetching the comment form data and saving it to the DB and return the result with context and other things via a render() method.
Now I know when we submit forms we should not return with render but rather with HttpResponseRedirect.
Now I want to that how can I make sure that a user's comment is added on that post? When using render() I was sending a new_comment variable with my context and checking it if its None or contains something later on my template and showing comment added in green color.
Now I can't send my context via HttpResponseRedirect, how to do this after adding comment? I read online and some forum said to use message? Is there any other option? Here's my code:

# 
def post_detail(request, year, month, day, post):
    # Gets a post object if found, or return a 404 error
    post = get_object_or_404(
        Post,
        status="published",
        slug=post,
        publish__year=year,
        publish__month=month,
        publish__day=day,
    )

    # Returns the list of all the active comments on a post.
    comments = post.comments.filter(active=True)

    if request.method == "POST":
        # A comment is posted
        comment_form = CommentForm(data=request.POST)

        if comment_form.is_valid():
            # Create a new comment but do not commit it to the database
            new_comment = comment_form.save(commit=False)
            # Assign a comment its respective post
            new_comment.post = post
            # Commit to the databse
            new_comment.save()
            return HttpResponseRedirect(
                post.get_absolute_url()
            )
    else:
        comment_form = CommentForm()

    context = {
        "post": post,
        "comments": comments,
        "comment_form": comment_form,
    }

    return render(request, "blog/post/detail.html", context)
#

Also, I tried using HttpResponseRedirect with reverse() but can't get that to work. So I used that get_absolute_url to return the url of my current post.
Version I tried:

return HttpResponseRedirect(
  reverse("blog:post_detail"),
  kwargs={
    "year": post.publish__year,
    "month": post.pubish__month,
    "day": post.publish__day,
    "slug": post.slug,
  },
)

But this above code returned Reverse for 'post_detail' with no arguments not found.
The URL is matched but the error was there.

#

Please tag me if you have any clue. I'll go offline in some time.

Anybody by any chance experience with wagtail. I'm trying to figure out what to do to get some sort of sub-menu/hierarchical menu to work. I kinda get mixed feelings- some github issues seems to suggest they aren't supported, yet the documentation/cms make it looks like there, and I'm just puzzled by it.

Let me know if you find the issue in the code @inland oak

lavish prismBOT

spotify/util.py line 77

response = get(BASE_URL + endpoint, {}, headers=headers)```
inland oak
#

Make your mind and use if, elif, else at least

split haven
#

so i'd just change it put?

#

get request was to fetch the base url and endpoint to make the api request

inland oak
#

U already invoke request with put(

#

U make at least two requests

split haven
# 
    if post_:
        post(BASE_URL + endpoint, headers=headers)
    if put_:
        put(BASE_URL + endpoint, headers=headers)

    response = get(BASE_URL + endpoint, {}, headers=headers)
    try:
        return response.json()
    except:
        return {'Error': 'Issue with request'}
#

isnt it already there?

#

for put and post

#

and then lastly the get req

#

i mean using elif or else and doing this is the same thing isnt it?

inland oak
# 
    if post_:
        response = post(BASE_URL + endpoint, headers=headers)
    elif put_:
        response = put(BASE_URL + endpoint, headers=headers)
    else:
        response = get(BASE_URL + endpoint, {}, headers=headers)
    try:
        return response.json()
    except:
        return {'Error': 'Issue with request'}
#

at least this

#

okay let me try that

#

doesnt work

except Exception as e:
Return {"error": str(e) }

#

Just read the error

oka lemme try

    if post_:
        response = post(BASE_URL + endpoint, headers=headers)

    try:
        return response.json()
    except Exception as e:

#

like this?

inland oak
#

Nvm

#

U should be able to read the error from console log

#

If your launched server

#

If u did not silent the error higher

#

you see console.log doesnt show anything when play/pause is clicked

Best practice would be writing unit tests instead of guessing where the error

split haven
#

or is it because of the function i wrote in the js file for the onClick?

inland oak
#

It could be anywhere

#

Without tests you can search for a long time

#

Tests show the place of the error

split haven
#

okay, thankss

inland oak
#

Try working with pytest

#

For back side

#

And check with smth like jest for front side

#

Just checking back should be enough to eliminate 90% of error places though

Hi,
I'm building an Blog App using Django and just added the comment functionality on my Posts.
An HTML page will display a Post and all the comments below it. Also, it will display a form to submit a comment on that Post.
Previously, I was fetching the comment form data and saving it to the DB and return the result with context and other things via a render() method.
Now I know when we submit forms we should not return with render but rather with HttpResponseRedirect.
Now I want to that how can I make sure that a user's comment is added on that post? When using render() I was sending a new_comment variable with my context and checking it if its None or contains something later on my template and showing comment added in green color.
Now I can't send my context via HttpResponseRedirect, how to do this after adding comment? I read online and some forum said to use message? Is there any other option? Here's my code:

# 
def post_detail(request, year, month, day, post):
    # Gets a post object if found, or return a 404 error
    post = get_object_or_404(
        Post,
        status="published",
        slug=post,
        publish__year=year,
        publish__month=month,
        publish__day=day,
    )

    # Returns the list of all the active comments on a post.
    comments = post.comments.filter(active=True)

    if request.method == "POST":
        # A comment is posted
        comment_form = CommentForm(data=request.POST)

        if comment_form.is_valid():
            # Create a new comment but do not commit it to the database
            new_comment = comment_form.save(commit=False)
            # Assign a comment its respective post
            new_comment.post = post
            # Commit to the databse
            new_comment.save()
            return HttpResponseRedirect(
                post.get_absolute_url()
            )
    else:
        comment_form = CommentForm()

    context = {
        "post": post,
        "comments": comments,
        "comment_form": comment_form,
    }

    return render(request, "blog/post/detail.html", context)
#

Also, I tried using HttpResponseRedirect with reverse() but can't get that to work. So I used that get_absolute_url to return the url of my current post.
Version I tried:

return HttpResponseRedirect(
  reverse("blog:post_detail"),
  kwargs={
    "year": post.publish__year,
    "month": post.pubish__month,
    "day": post.publish__day,
    "slug": post.slug,
  },
)

But this above code returned Reverse for 'post_detail' with no arguments not found.
The URL is matched but the error was there.

Did you load static in the templates?

#

{% load static %}

marble spire
#

can u check my code

#

yes i did that @uneven radish

stable sentinel
#

OK... I just got a nosebleed cause of this lol, someone please help.

I am rendering some images from a database

    title = models.CharField(max_length=50)
    description = models.TextField()
    technology = models.ManyToManyField('Category', related_name='projects')
    link = models.URLField(blank=True)
    image = models.FilePathField(path='img/')```
where the img/ is under my static directory. Like this my admin panel keeps crashing with a FileNotFound exception cause it can not seem to find the img / directory. If I change the path to static/img than admin panel works well but I get a 404 for the image cause django is looking for it in static/static/img. regardless of what I define there as path it will prefix it with static/

I had the exact same problem a week ago, and all of a sudden it was working with the img/ path. Like, everything worked. Now I added a new item to the DB and its doing the same thing again. 

This is suuuper weird....
#

I found the same issue on stackoverflow from some months back but it has no answer. 🤷‍♂️

Hi can some one help me with this error Invalid block tag on line 200: 'static'images/home_slider.jpg''. Did you forget to register or load this tag?

native tide
buoyant geode
#

style="background-image: url({%static'images/travello.jpg'%})"

#

while doing this I get error

#

I even did {% load static%} and in setting.py STATIC_URL = '/static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] STATIC_ROOT = os.path.join(BASE_DIR, 'assets')

native tide
#

what library are you using

charred epoch
#

oh sorry

native tide
#

is home_slider.jpg inside of static/ folder

#

@buoyant geode

buoyant geode
#

yeah

#

see when I use static for "{% static 'styles/bootstrap4/bootstrap.min.css'%}" this it works properly but when I use for this style="background-image: url({%static'images/travello.jpg'%})" it throws me error @native tide

native tide
#

though

#

not travello.jpg

#

?

buoyant geode
#

see this error occurs for this type of lines url({%static'images/it-can-be-anything.jpg'%})"

#

and there are few images inside url(....)

#

for every image inside url when I mention static this error occurs

buoyant geode
#

I did this style="background-image: url('/static/images/travello.png')" instead of this style="background-image: url({%static'images/travello.jpg'%})" and it works @native tide

rustic narwhal
#

u wrote {% load static %} ?

buoyant geode
#

yeah I did

rustic narwhal
#

because the error says "Invalid block tag on line 200: 'static'images/home_slider.jpg''. Did you forget to register or load this tag?"

#

so you have not loaded static

buoyant geode
# 
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]
STATIC_ROOT = os.path.join(BASE_DIR, 'assets')```
#

@rustic narwhal but it did not worked

#

it worked after style="background-image: url('/static/images/travello.png')" doing this

#

instead of this style="background-image: url({%static'images/travello.jpg'%})"

rustic narwhal
#

try using just like this {% static 'images/travello.jpg' %}

#

try not using url

buoyant geode
#

okay

rustic narwhal
#

did it work ?

buoyant geode
#

No @rustic narwhal

what is zip_file?

fleet quest
#

I've tested with other parts of the form (which takes in an excel file) & I'm not able to functions to process as files, not file paths.

versed lotus
#

okay, yea, but what is it? ZipFile expects a path, path-like, or file-like object. what is form.invoice_zip.data then?

fleet quest
#

it's a zip file? I don't know if it's being processed by file name or as a file object.

#

I'm using Flask requests for this.

versed lotus
#

if it's flask, it seems to be some kind of FileStorage object. not a file-like. not sure how to use that. if it's even "file-like" and can be used like that

fleet quest
#

so I'd need to convert FileStorage to a file-like object?

versed lotus
#

maybe, I wouldn't know for sure. Never done it like that.

#

you can use invoice_zip.save( ... ) - see the flask docs how to securely save uploaded files

fleet quest
#

good idea. maybe then I can find out whether it's really storing as an object & not as a file name.

@dusk portal request.files is a MultiValueDict, it's not a callable.
Access files via request.form['form_name'] instead of calling it request.form('form_name')

opaque rivet
# dusk portal ```py STATICFILES_DIRS = [ os.path.join(BASE_DIR,'static') ]```

This is incorrect. STATICFILES_DIRS CANNOT include the STATIC_ROOT. STATIC_ROOT = where staticfiles are collected when you collectstatic.
STATICFILES_DIRS = the locations of staticfiles to be placed in the static root when you collectstatic. This cannot include the static root.

Also when you use the static tag in your jinja2 template, it has nothing to do with your static root or static dirs - that uses your static URL.

Hi, anybody using FastAPI?

I have a test server running, now I want to implement a "shutdown" API, when the server receives this API, it should quit the execution (i.e. process exit), is this possible?

opaque rivet
#

@dusk portal that is an error coming from your files, because the only time you mention thumbnail is accessing the files.

#

I'd debug the view to see if it's actually receiving the file data. Note that your request containing file data must have the content type multipart/formdata

Ig Problem isnt in my view
Or model as when I'm doing same thing from admin panel it's working

I would check the view to see what files it's receiving.

How to make a Http request to the backend, I mean I am using a api to transfer some dataa from dashboard but whenever the data is uploaded in the api how can will my backend know that some data has been uploaded?

velvet yew
#

How can I troubleshoot why is my Django API's response time awful when doing authentication? I've got a simple endpoint for testing that goes like:

@api_view(["GET"])
@authentication_classes([BasicAuthentication, SessionAuthentication])
@permission_classes([IsAuthenticated])
def test(request):
    if request.method == "GET":
        data = {"user": request.user}

        return JsonResponse(
            data=data,
            status=200,
            json_dumps_params={
                "default": str,
                "ensure_ascii": False,
                "indent": 2,
            }
        )

I'm getting ~50 ms response time when commenting out the authentication classes, but 1.5 - 2.5 sec when I'm using authentication. The DB has a response time of around 25 ms from where I run the web server (locally for now)

eternal oxide
mystic vortex
#

How can I get a value from my html to my python script

opaque rivet
#

@velvet yew simply because the authentication class adds extra middleware. 50ms is good.

#

@mystic vortex I don't know what you're trying to ask. Do you want to log your API requests?

velvet yew
opaque rivet
#

Oh I misread!

#

@velvet yew does removing BasicAuthentication class help anyhow? I don't see you using that anyway.

#

Because your request will go through that middleware first before session auth.

velvet yew
#

Oh let me try I just added it because the guide said so

#

It does make is fast but then I can't authenticate anymore

#

And I get {'detail': 'Authentication credentials were not provided.'}

#

So I guess it's fast because it fails lol

Robots.txt is a bad idea, because then the hidden url is exposed

how can i get the output like above json output, like to create a dictionary output for foreign key linked table
in Django

Especially if you can't allow just certain IPs.

dense slate
#

You can create a serializer, if that's what you're wondering?

#

To convert an object to JSON.

native tide
#

yes , but i need to get foreign key table details for specific field
i.e in that output ,student field got every detail from school record

#

fetch student school record from School table as result for that field

guys is there like a front end framework for python?

#

like, html but python based

#

I'm learning django atm, and there's mostly backend stuff

#

and some html for frontend

#

maybe there's something like GrapesJS but for python yk

dense slate
#

Even if there is one I expect it would be a very hacky way to do things.

it will appear in advance before the admin panel, moderators only will need to write correct password, before they access admin panel where they will properly authentificate as second step

#

whilisting ip is required for more... thorough defense

#

we could white list all ips from our company network

#

in one line/rule

#

something like....
Allow 165.65.0.1/16, if I wrote it correctly

#

will allow all ip addresses from 165.65.0.1 to 165.65.255.255 range

#

or actually even better.

#

we could allow only access to servers, from computers which have enabled our private company VPN 😉

#

which could connect only from company network ;b

# native tide how do i update a part of the html without refreshing the page? do i need a api ...

There are at least three ways to do this that I am aware of:

  • AJAX. I've not personally worked with AJAX, but it has been around for a number of years.
  • JS: This is definitely a candidate for managing page behaviour. I'm getting ready to work with JS, researching a Framework currently. However, so far I've used the following...
  • HTMX: I've been working with this tech recently. It only has a couple of lines to call the JS script (just as you would for a css framework such as bootstrap/tailwinds). You can then invoke all sorts of tricks to update partial pages. The documentation is solid. I'm using it in a couple of instances in a Django web application to amazing effect. There is no script overhead that I can observe, and it results in really fast DB updates. In short, I'm astonished at how effective HTMX is. If you want to see it in action DM me.

Whatever the case, both the above methods can be researched to deliver what I believe you are looking for.

AJAX is just a fancy acronym for 'asynchronous HTTP requests'

stray notch
#

is there something like django-q, but for flask? (ie. pip installable, all python)

dense slate
#

Like RabbitMQ?

#

or redis

#

I think those two are agnostic.

stray notch
#

rabbitmq uses erlang, which isn't an option. needs to be python

dense slate
#

Redis is in C at least... why does it have to be written in python?

stray notch
#

I'm running it on pythonanywhere, which is limited

dense slate
#

Limited how?

stray notch
#

I think you can use redis as a broker for django-q

stray notch
dense slate
#

I see. Are you using the free tier? You an get a linux server for $5/month on DigitalOcean. Having those kind of limitations seems like a huge PIA.

stray notch
#

haha. Agree.

thanks @dense slate will consider other options :)

still gotta test that message though

you can't insert correct username/password?

oh I can

inland oak
#

it is not accepting them?

rustic sky
#

it is

#

it's the message I'm inda worried about

#

well that's interesting, it shows on my iPad

#

I'm gonna guess because of cache

inland oak
#

why are you worried about the message

#

yeah, test with freshly reopened incognito browser

#

clean from cache by default

rustic sky
#

well it ain't showing there either, but whatever

#

I know it at least works

#

I kinda feel like combining it with specific IP access, but my IP is dynamic and I'm not always home

so that... nah

#

well, thanks man

inland oak
rustic sky
#

now, I don't have to worry for a while

that's basically everything I needed to take care of

inland oak
#

just in case, you can allow pass with IP or password being right

# 
location / {
      satisfy any;

        allow 217.115.32/24;
        allow 127.0.0.1;
         deny  all;

        auth_basic           "You shall not pass!";
        auth_basic_user_file /etc/nginx/htpasswd;
  }
#

in this way

#

satisfy any; makes allowing if at least one of the rules were pased

rustic sky
#

mhm, lol

#

noted!

#

this project took longer than I wanted it to, but at least I didn't rush and possibly make an error (I made sure I didn't)

inland oak
#

I have a project I am working on already a year %

rustic sky
#

now I'm kinda "burnt out" from it for a while, so I'm just gonna leave it running for a bit before I start making the changes

#

yeah, it is a bit big one.

#

more off than on tbh

#

it is meant for infrastructure of 200+ servers at minimum

#

and at the same time they hired just one developer

for everything 😐

#

I am not picky I guess while I am just learning stuff

rustic sky
#

oh god

#

that's a lot for one person

#

I was just creating my website

#

yeah that's a lot (maybe too much)

it is a good learning experience at least

Hello, I need help in django conform delete

what i want to do is show the user the option "yes" or "no" when deleting a contact

  1. yes = delete contact
  2. no = return to contact list - i know there is this back option (window.history.go(-1);)

my template conform_delete.html:

    <div class="form" style="text-align: center;">
        <h2>Are you sure you want to delete the "<b>{{ obj.name }}</b>" contact?</h2>
        <!-- <form action="/api/contact-list/" method="POST" novalidate class="test">
        
            {% csrf_token %}
            <br><a href="{% url 'contact-list' %}"><input class="btn btn-success" id="yes" name="yes" type="submit" value="Yes"></a>
        </form> -->
        <a href="{% url 'contact-list' %}"><input class="btn btn-success" id="yes" name="yes" type="submit" value="Yes"></a>

        
    </div>

my views.py:

class DeleteContact(DeleteView):    
    model = AdressEntery
    context_object_name = "obj"
    template_name = "main/adressentery_confirm_delete.html"
    success_url = reverse_lazy("contact-list")  # this is redirected to a specific url for the parameter using the name expressed in urls .py   
    def dispatch(self,request, *args, **kwargs):   #this method allows us to use methods such as (post, get, put ..) and allows us to return HTTP methods such as (response, redirect)
        return super(DeleteContact, self).dispatch(request)  #dispatch method will override the second method and allow us to do redirection
        #return redirect('/api/contact-list/')   #render(request, self.template_name, {})
    def get_queryset(self, *args, **kwargs):
        queryset = super(DeleteContact, self).get_queryset()
        queryset.filter(id=self.kwargs['pk']).update(active=False)
        return queryset   # filter by clicked contact card get id and set active false
#

note: I don't want to delete my object, I set the flag acticve = false.

If I put a button in the form, the contact object in the database is deleted,
but without the form just by clicking on the previous delete link leading to conform_delete, my contact is instantly set to active = false so this button only does redirection.

#

is get_queryset even called?

i dont think it would be

though in this form my admin page raises a FileNotFound exception. If I change path to static/img/ than admin page works fine but, django keeps looking for file in static/static/img/

if __name__ == "__main__":
    run()
#

its still not 0.0.0.0

echo summit
#

0.0.0.0 means the program accepts connections for all IPs it can handle

#

As opposed to specifying the ip

mystic vortex
#

yea i want that

echo summit
#

But 0.0.0.0 is still not a valid ip

mystic vortex
#

how can i get that '

echo summit
#

You need to use either local host or 127.0.0.1

#

(In your browser or whatever you’re using)

mystic vortex
echo summit
#

You can’t

#

0.0.0.0 is reserved as a placeholder

mystic vortex
#

so how an i accept response from everyone

#

i am making a dashboard

raw compass
#

When I run your code

 python discord_flask_wildcard.py
\ * Serving Flask app 'discord_flask_wildcard' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on all addresses.
   WARNING: This is a development server. Do not use it in a production deployment.
 * Running on http://192.168.0.4:31186/ (Press CTRL+C to quit)
echo summit
#

So if you have 0.0.0.0 in you config the program will accept connections for all ips the pc has

mystic vortex
echo summit
#

That is usually local host (127.0.0.1) and all ips that are assigned

mystic vortex
#

?

#

i want to make it 0.0.0.0

echo summit
#

Wdym make it 0.0.0.0

#

You want to use 0.0.0.0 in your browser to connect?

mystic vortex
#

cause i am making a bot dashboard

echo summit
#

Yes that means you need an IP address that is reachable from the internet

mystic vortex
echo summit
#

Then you specify 0.0.0.0 in your config and the program will accept all connections regardless of the ip used to connect to the program

mystic vortex
#

i am new to web dec

#

dev

#

i just started a day ago

echo summit
#

So let’s say your server has access to 2.3.4.5

mystic vortex
#

ok

echo summit
#

That means that traffic for that ip is sent to your server

#

Then the program will accept connections if users use that ip to connect

mystic vortex
#

i am trying to make it accept all requests but no its not accepting

#

its only accepting from me

echo summit
#

What ip are you using to connect?

mystic vortex
mystic vortex
echo summit
#

ok, so where are you running the porgram?

Hey there, wanted to quickly ask if I (via django for-loops) generate Id's for Div elements. I can not target them via css/scss right? I have to do it via JS ?

echo summit
#

why do you want to do that in the first place

#

ids and classes are mainly there to identify their css style

#

if you want a unique id for targeting them in js code you can add an additional id or class

tough crane
#

I want to change the color of some of them. Because some of them have different backgrounds so in order for them to be readable nicely, they need to have different text colors.

#

Like if you see here, the second one is very badly readable. So I want to change the text color of it.

Screenshot_2021-09-14_at_13.08.57.png
echo summit
#

are the images predetermined or do they change

#

also you can do inline styles

tough crane
#

Everything is loaded from a Database. So the image always stays the same.

echo summit
#

then why bother generating ids

#

just make two ids and style them independently

#

or make a general style and then add an inline style like this:

# 
<h1 style="color:blue;">A Blue Heading</h1>```
tough crane
#

The id's are generated automatically because there is a for loop that is generating the elemente.

#

i can not add inline styling

#

That's the code that generates these two images (cause there is only two right now).

echo summit
#

then you could add the colour you want to the portfolio object and add that to the repeating template

tough crane
echo summit
#

you could do a default color

#

like py {{portfolio.colour if portfolio.colour else "#fff"}}

#

that means that if the colour is set it uses that colour else it uses the default

tough crane
#

ahh I see. that could be helpfull. Thank you ❤️

hi there I am using django LoginView to login a user and on invalid credential it is not showing any error

echo summit
regal fossil
#

i tried

{% if messages %}
{% for message in messages%}
  {{ message }}
{%endfor%}
{%endif%}

but its not working

echo summit
#

is that the whole template?

regal fossil
#

no i am using default and login

echo summit
#

can you show the whole file/template?

regal fossil
#

this is default

default.jpg
#

login template

login.jpg
#

views using built in LoginView

views.jpg
echo summit
#

they will just add the text to the html but it will just be ignored

Hey, I want to store the _Rolename in a separate variable as a property (string) then what should I do ?

  @property

    return self._Rolename  # Is this correct?
echo summit

tough crane
#

And then in your views you will need to add a message object. Like this for example.

#

Now in my template the message "your profile has been updated" will appear.

regal fossil
tough crane
regal fossil
#

how ?

tough crane
regal fossil
#

Thank you I just found the problem but I will look it as well
I am using my own forms so they dont have that functionality to show errors
thats why I am not seeing errors

tough crane
#

ah but you can just ask is form valid normally if it builds on a default form. If not then ye you gotta build that in.

regal fossil
#

yeah

tough crane

but I'm sure you find something. Django has lots of answers

scroll to where error is

aka red text

#

send screenshot

#

so it cant find the template

#

lets try to figure out why

#

is your html file named exactly index.html

#

and is in templates

#

its not in templates

#

templates is a folder

#

create that folder in your project dir and put the html file in there

#

it will be fixed

#

send screenshot of files again

#

yeah

#

would help

#

@native tide actually just send entire project folder

#

it could be the placement of files or the code itself

#

i need it all

lavish prismBOT

Hey @native tide!

It looks like you tried to attach file type(s) that we do not allow (.zip). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a.

Feel free to ask in #community-meta if you think this is a mistake.

Which is best to use for django views, def example(request) or def example(response),?

#

Started learning django a few days ago

dusk portal
#

What r u saying lol

#

Response is like return but in rest Framework

#

;_;

#

And and yes in both the parameter is request

#

Example

def babe(request):
     return render(request,"babe.html")```
# 
from rest_framework.response import Response
def babe(request):
    return Response("babe")
#

Or JSONRESPONSE

We won't use html here as it is given my django

like

the Python stdlib socket library?

do the server and robot need to talk to each other?

or one way only?

class Item(models.Model):
    collection = models.ForeignKey(Collection)
    object_id = models.UUIDField()
    seq = models.PositiveSmallIntegerField()

from the frontend Item can be drag&dropped to change its seq value. Hence i need to update the seq value. If seq value is duplicated, i have to add 1 to the previous one and place the new one instead. I am thinking collecting all the items and updating each one but is there any other optimal way to achieve this?

that's just a HTML thing

in django I am storing some images for my portfolio projects in
model.FilePathField(path='/img') and this makes my admin panel crash with a FileNotFound exception cause of the /img dir.
Project photos do not load cause django is looking for them in /static/static/img instead of static/img.

If I change the path attribute to model.FilePathField(path='static/img') admin page works but I still get a 404 cause django is looking for files in static/static or static/home...

Someone please give me a hand cause this is the only thing holding me back from deploying my portfolio page. And its been bugging me for weeks by now...

#

I truly have no idea which constant in the settings.py is prefixing the path with static. I have played around with a multitude of things
