How to use Django flash message in thread?
I have a view that triggers a long execution time function, at the end of this function I need to notify the user via flash message of the execution result. The function is in a thread. This is my code... from threading import Thread from django.contrib import messages def long_time_view(request, pk): def thread_func(): #stuff if success: messages.success( request, "Hurrah.", ) else: messages.error( request, "Upss.", ) messages.info(request, "Started Work.") thread = Thread(target=thread_func) thread.start() return redirect(request.GET.get("return_to", "/")) The Problem The message that notifies the user that the job has started is displayed but the results are not, even after the page is reloaded. So my question is how to show the results to the user from the thread. -

upload multiple files asynchronously before submit form Django?
Intro: I have Django web app where users are allowed to create posts. Each post has multiple images that are associated with that post. What I want to do: I want such that when the user uploads each image to a form. I want to use Filepond javascript library for remove image, add more image and previews of selected images. The issue: The code below is getting error NOT NULL constraint failed: core_filemodel.post_id I want to add multiple images to a django form asynchronously before form submit.I have the Javascript code for uploading of the images on the client side and asynchronously adds it to my server.

How to render redirect a URL with an int: parameter in Django views.py?
I'm trying to make a form in Django that displays errors when the form isn't filled out properly under a specific account. I want it to reroute to the same page as the form, and the url has to have an int: parameter. For my urls.py, I have 'edit/int:user_id>, views.edit. Where I'm struggling is how do I pass the render redirect in the views.py? I've tried render redirect('/edit/int:user_id'), ('/edit/int:user.id'), ('/edit/{user.id}'), etc, and NOTHING is working. Every time I just get 'path not found.' How do I write a redirect in views.py with an int parameter, based on what I have for my urlpatterns? -

How to embed this python code into a simple HTML website?
I am working on a website which will take input and do some calculations and give output. I need to write this calculation code in python. But since this will be used by other users, I want it to be in form of a website so I can deploy it. Just like we can embed JavaScript code into a html page, can we do the same thing with python?? the code will be very simple, around 5-10 calculations. I know there are ways to do this with Flask or Django, but I was wondering if there was an easier way by just embedding python code in the HTML file. Would it be better if I just create a Tkinter GUI web-app & turn it into an executable file? below is the type of code I'll use on the website. Of course, the real code will be a little more complex and longer. But basically ill be asking for input and do calculations with it & then print the output Example Python code Length = input(int("Insert the Length")) Width = input(int("Insert the Width")) Print("area of this rectangle is: "+ Length * Width) -
Django How to Add Base Form Template Context Processer
In my navbar I have a newsletter button that pops up a modal. In the modal there is a form that I can use to get the email and do some form manipulation. Since this modal is in the base template, the form must be available for all urls. I have added 'blog.context_processors.email_form' in the settings, and a context_processer.py file with the below info: from .forms import EmailForm def email_form(request): return { 'email_form': EmailForm() } In my forms.py I have: from django import forms from .models import Email class EmailForm(forms.ModelForm): email = forms.EmailField(label='', widget=forms.EmailInput (attrs={'id': 'emailInput', 'class': 'article-search', 'placeholder': 'Enter yorffreur email here...', 'type': 'text'})) class Meta: model = Email fields = ['email'] def clean_email(self, *args, **kwargs): email = self.cleaned_data.get('email') qs = Email.objects.filter(email__iexact=email) if qs.exists(): raise forms.ValidationError('This email already exists.') return email In the base templates I have included the form as {{ email_form }}. But I do not know where to add the form manipulation. Usually I add it in the views but I'm new so I am an unsure how to do this. -

Django returns NoReverseMatch instead of Updating the div with Ajax
Description I am creating a like button for a comment that was made on a post. When the user clicks on the like button, Django gives a NoReverseMatch and the page doesn't update automatically. After I refresh the page, it shows that the like was updated in the database, despite the NoReverseMatch error. What I tried? Initially, the issue was with the csrf_tokens. So, I added the csrf_exempt decorator, so it is definitely not the issue. I played a lot with the urls, and tried adding the comment id to the parameter, but it doesn't seem to help. Question How can I resolve the NoReverseMatch error and make it so that AJAX automatically changes the button from like to dislike. urls.py path('post/<int:pk>/like-comment', like_comment, name="like_comment") view.py @csrf_exempt def like_comment(request, pk): comment = get_object_or_404(Comment, id=request.POST.get('id')) liked = False if comment.likes.filter(id=request.user.id).exists(): comment.likes.remove(request.user) liked = False else: comment.likes.add(request.user) liked = True context = { 'comment': comment, 'is_liked': liked, 'total_likes': comment.likes.count() } if request.is_ajax(): html = render_to_string('blog/like_section_comment.html', context, request=request) return JsonResponse({'form': html}) main.js $(document).ready(function(event){ $(document).on('click', '#like-comment', function(event){ event.preventDefault(); var pk1 = $(this).attr('value'); // comment id var pk = $(this).attr('data-value'); // post id $.ajax({ type: 'POST', url: "like-comment", data: {'id': pk1, 'csrfmiddlewaretoken': '{{ csrf_token }}'}, dataType: … -

Celery is not loading tasks from one app out of five

Form field defined in View does not appear in the returned `cleaned_data` dictionary
I am working on a reports page for a django app. This particular app (not written by me) has a reports page, where all report links appear with their forms. That is, if there is an updates timeline report page, it will appear here together with all of its form fields (time granularity, include security updates, etc) and a button that will take you to the updates timeline page to view the results (or chose different values). All other report links appear in this general page as well. Now to my problem: I want some specific, not required form fields to not appear in the general reports page, but instead only when the user accesses the actual report page. That is because they are ModelChoiceFields with thousands of entries, that slow down the rendering of the general reports page (there are many forms for different pages there, so it adds up). The way I do that is the following: I declare the fields as forms.HiddenInput in forms.py, and then inside my view, in the form_valid() function, I redefine the fields as ModelChoiceField. That way, the fields appear only when the user has submitted their first form (the one from the … -
How to save the choices in the save() in the model
I want to be able to save and retrieve the Choices , but depending on a certain value in the fields.

Django 3: how to serve static images whose path is defined by a model attribute?
I'm trying to use images in Django 3 Debug mode as follows: on the admin side, get a list of the images contained in projects/static/img/ directory in the editing forms; on the front-end side, display the actual image of the class instance. Here's my code: settings.py STATIC_URL = '/static/' projects/models.py from django.db import models class Project(models.Model): img = models.FilePathField(path = 'img/') Images are located in the projects/static/img/ directory. When I create a new class instance with python manage.py shell: from projects.models import Project t = Project(img = 'img/test.jpg') t.save() The image gets displayed correctly on the front-end side. The problem is, I can't access the forms on the admin side. I get: FileNotFoundError at /admin/projects/project/add/ [Errno 2] No such file or directory: 'img/' I also tried python manage.py collectstatic that copies the projects/static/img/ folder into /static/img/ but nothings works, the admin side still gets the same error. Any suggestion on how to solve this? -
