Django - How to carry the filters to the next view?
I imagine something like this is possible in Django, but I don't know how to implement it: I have a TableView, which has filters to filter the displayed queryset. I, then, have a DetailView which you can access from the TableView, to see the details of each element in the queryset. The DetailView has a form, which uses the POST method. I can successfully send the form, and redirect to the TableView after the POST call. My question is, how can I make it so that after the user calls the POST method in the DetailView, and it redirects again to the TableView, the TableView keeps whichever values were on its filters? I imagine I would have to either get access to the full request on the TableView (because it includes the ?param1=?param2= etc.), or be able to send the values in the filters when I call the DetailView. -

how can I display just plain text among posted information which have images, tables from CKEditor in Django?
As same as stack overflow does in a homepage, showing questions without images just with tags, I want my blog site to show just a title and a header in a list of blog posts page. the uploaded image ruins css card section and tables display half of it. so I would rather display just plain text. I am currently using Django(3.1.5), CKEditor. My question is; How to get a plain text from ckeditor?, how to catch a image uploaded from CKEditor, if I can, can I save those images into the model(ImageField or FileField)? -
Django forms - Allow a user to create a group for other users
I am trying to let a user create a "club" (basically a group) where the user later on can add users to. Currently it only displays the HTML text and the button, but no text field. Any suggestions would be appreciated since I am fairly new to forms. Model class Club(models.Model): owner = models.CharField(max_length=30) topic = models.CharField(max_length=30) start = models.DateTimeField(verbose_name='start date', auto_now_add=False) end = models.DateTimeField(verbose_name='end date', auto_now_add=False) account = models.ManyToManyField(Account) Views @login_required def add_club(request): if request.method == "POST": form = AddClubForm(request.POST, instance=request.user) print(form) if form.is_valid(): form.save() return HttpResponseRedirect(request.path_info) else: form = AddClubForm(instance=request.user) return render(request, 'page/club.html', { "form": form, }) Form class AddClubForm(forms.Form): owner = forms.CharField(required=True) topic = forms.CharField(required=True) start = forms.DateField(required=True) end = forms.DateField(required=True) class Meta: model = Club fields = ( 'owner', 'topic', 'start', 'end', ) Template <form method="POST" action=""> {% csrf_token %} <div class="col-md-6"> <label class="labels">Create a club</label> {{ form.owner }} <input class="btn" type="submit" value="Add club"> </div> </form> -
How to log a django view
I'm learning to log and I'm not sure what I'm supposed to do with the logger in my view since what I've read around doesn't seem to work or I'm just not understanding something. This are my settings for the logging: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'class': 'logging.StreamHandler', }, }, 'loggers': { 'todo': { 'handlers': ['console'], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), 'propagate': True, }, }, } This is the view and the logging part: from rest_framework import generics, filters from todo import models from .serializers import TaskSerializer from django_filters.rest_framework import DjangoFilterBackend import logging logger = logging.getLogger(__name__) def myview(request): logger.error('Something went wrong') class ListTask(generics.ListCreateAPIView): """ API view to retrieve list of tasks or create new tasks """ queryset = models.Task.objects.all() serializer_class = TaskSerializer filter_backends = [DjangoFilterBackend, filters.SearchFilter] filterset_fields = ['date'] search_fields = ['description'] class DetailTask(generics.RetrieveDestroyAPIView): """ API view to retrieve or delete a task """ queryset = models.Task.objects.all() serializer_class = TaskSerializer -
How to insert a Django template tag + HTML element in a HTML page with Javascript
How can I safely add a piece of HTML with Django template tags in it using Javascript? For example, if I have something like this in my template: <div id="some-element"> <span id="my-tag">{{ my_data }}</span> </div> <!-- rest of the html page --> If I were to use a script to just edit the innerHTML of the div, like the script below, it'd would just read {{ other-data }} as a string. How can I make it become an actual Django template tag? <script> document.getElementById("some-element").innerHTML = ` <h1>This is may new data {{ other-data }} </h1> {% if value %} <p>This is an if statement</p> {% endif %} ` </script> -
How to Stack Multiple Search Parameters in URL with Django and Ajax
I'm trying to create a filter system on a webpage such that the user can bookmark their searches. The page loads from the basic url: path('foobar/counts', views.foobarCount, name='foobar_counts') This URL loads the proper template on top of the base template and includes everything needed. From there, a series of filters are set up, which send an ajax request to the server. The user can select as many or as few filters as they'd like. The Ajax url is set up as follows: path('foobar/counts/filter', views.foobarCountFilter, name='foobar_count_filter') This all works just fine when the user starts at the foobar/counts URL, but when they want to paste in something like: /foobar/counts/filter?startDate=2001-01-12&endDate=2021-01-12&startComp=2021-01-01&endComp=2021-01-31&assigns... The system properly receives the Ajax request and brings back the proper information, but it does not include the other templates needed to load the webpage. It displays as essentially a plaintext version. Is there a minimally invasive way to retroactively load all the necessary templates when pasting in the search URL? -

Enforce or test on_delete behavior of all ForeignKey fields using a specific model
Let's say I have a proxy user model as class UserWithProfile(User): profile_description = models.TextField() class Meta: proxy = True ordering = ('first_name', ) I want to make certain that all data which could in the future be associated with a UserWithProfile entry is deleted when this profile is deleted. In other words I want to guarantee the on_delete behavior of all existing and future ForeignKey fields referencing this model. How would one implement either a test checking this, or raise an error when another on_delete behavior is implemented? I know it would be possible to make a custom ForeignKey class, which is what I will be probably doing, ... class UserWithProfileField(models.ForeignKey): def __init__(self, *args, **kwargs): kwargs.setdefault('to', UserWithProfile) kwargs.setdefault('on_delete', models.CASCADE) super().__init__(*args, **kwargs) ... however that couldn't stop future users from using the ForeignKey class with a different on_delete behavior. -

Specify multi-language description tag when using Django i18n
I recently published a webapp made with django, which serves content in both Italian and English. To accomplish that, I used Django's internalization pack, i18n. The content is currently being served according to user's accept-language header, with Italian being served if the user asks for it language in the header, and English being the default for when the header is absent or containing any other language code. In addition to that, I also have the following tags <link rel="alternate" hreflang="it" href="https://mywebsite.com/it/" /> <link rel="alternate" hreflang="en-us" href="https://mywebsite.com/en-us/" /> <link rel="alternate" hreflang="x-default" href="https://mywebsite.com/en-us/" /> Which I accomplished with the following urls.py config: urlpatterns += i18n_patterns( path('jsi18n/', JavaScriptCatalog.as_view(packages=['appname'], domain="django"), name='javascript-catalog'), ) as suggested in the official docs. I would like my website homepage (which is the only publicly accessible page of the website) to have a meta description tag to be shown to Italian users, and one in English. What's the best way to accomplish this with my current configuration, given that ultimately it's a single page that's being served and not one per language? -

Can I get the property of a specific object in a Django template?
I am using django-filters in my project. Let's say I get this address after a search: ?title=my title&ms=8 As you can see, I've searched for 'my title' and for a manuscript which the user sees as 'my manuscript', but whose get parameter (and ID) is 8. Now, I'd like to add to my template a courtesy 'you've searched for' field. How can I show the title of that manuscript, rather than its ID? I already have the ms objects in my view: mstunes = MsTune.objects.all() ms = Manuscript.objects.all() <- manuscripts f = MsTuneFilter(request.GET, queryset=MsTune.objects.all()) return render(request, 'manuscript/mstune_list.html', {'mstunes': mstunes, 'f': f, 'request':request, 'ms': ms}) and I can indeed access them with {{ms.all}}. Is it possible to do something, in pseudo code, like: show the ms.title of the ms object with id = request.GET.ms ? -

Why isn't the BooleanField changing value in Django models?
I'm working in an Auction website which let the user list an auction and close it afterwards. The auction models has a boolean field called is_closed that stores if the auction is closed or not. When the user clicks a "Close Auction" button, he will be lead to this view that only changes the value of this field (that is false by default) and then saves the changes. def close_auction(request, auction_id): if request.method=="POST": target_auction = Auction.objects.get(id=auction_id) target_auction.is_closed=True target_auction.save() return HttpResponseRedirect(reverse('auction', kwargs={'auction_id':target_auction.id})) However, the field doesn't change, even though I am redirected to a html page that is loaded when the auction is closed successfully. When I go to the admin/ page the is_closed field indeed is unchanged (still marked as false). If what I did here is illegal, why there is no error message? Here is the Auction model: class Auction(models.Model): title = models.CharField(max_length=64) description = models.TextField(max_length=100, default="") image_url = models.CharField(max_length=100, default="https://elitescreens.com/images/product_album/no_image.png") category = models.ForeignKey(Category, on_delete=models.CASCADE, default="", related_name="auction_category") bid = models.OneToOneField(Bid, on_delete=models.CASCADE, null=True) creation_date = models.CharField(max_length=30, default="-----") owner = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True, default="") is_closed = models.BooleanField(default=False) Any ideas? -
Django admin actions bar missing? Template expecting "action_form" context variable but mine is showing "action_confirm_form"
As the title says, I'm having an issue that I cant seem to find any reference of anywhere else online. I was working on creating a custom Django admin action that provides and intermediate page for additional request data before updating the selected models. I followed these posts to accomplish this: Displaying an Admin Action Popup and Displaying an Admin Action Confirmation Page. I got everything working and then I went back to add some comments and after the server restarted when detecting changes, the admin action bar completely disappeared (see screenshot below). Another thing to note, my Django project has two separate apps, each with their own admin site and the actions drop-down disappeared from both sites for all model's change list view.

Wagtail - How to save a record which uses InlinePanel containing M2M
I have a model which uses an InlinePanel to reference another model (ClubTimetable) which itself contains an M2M relationship to DayOfTheWeek. It seems as though I am unable to save the record because ClubTimetable is not yet saved and cannot create the M2M relationship to DayOfTheWeek, causing the following error: "<ClubTimetables: Club Timetable (str) 18:00:00>" needs to have a value for field "id" before this many-to-many relationship can be used. What can I do to solve this issue? My models look like this # ClubManager @register_snippet class ClubManager(ClusterableModel): name = models.CharField('Club name', max_length=255, help_text='The name of the club.') panels = [ FieldPanel('name'), InlinePanel('club_timetable', heading='Timetable Information') ] # ClubTimetables class ClubTimetables(Orderable, AddressBase): attached_to = ParentalKey( 'club.ClubManager', related_name='club_timetable') weekday = models.ManyToManyField(DaysOfTheWeek) start_time = models.TimeField() end_time = models.TimeField() panels = [ ... ] + AddressBase.panels # DaysOfTheWeek class DaysOfTheWeek(models.Model): weekday = models.CharField(max_length=9) def __str__(self): return self.weekday Visually, it looks like this (Initial) (Adding timetable) -

preventDefault doesn't always work and the event is executed
I have encountered such a problem that the cancellation event of the form submission does not always work, namely in 30% of cases the event is not cancelled. I send a request by GET method to Django server and get json from it. In 70% of the cases I get the json and my function is already called which handles that json. But in the other 30% I get the json and it is immediately displayed on the screen and I get this text in the console: "content.js:200 JSON Formatter: Type "json" to inspect." Can you please tell me why this happens and how to fix it? let form=document.querySelector('form') form.onsubmit=(e)=>{ e.preventDefault(); setTimeout(()=>{ fetch(form.action, { method: "GET", }) .then(response => response.json()) .then(function(json) { if (json.status){ caseFormation(json) } }) .catch(function(error) { console.log(error) }); },1000) } -

as a relative noob to django I have been creating a users app. I would like a logged in superuser to have to reauthenticate if they access the admin area having used the rest of the app. I am trying this custom middleware that I have written. Is there a django integrated solution to this problem already, and are there any issues that you can see with my code? from django.shortcuts import redirect from django.contrib import messages from django.contrib.auth import logout import re class ReauthenticateMiddleware: def __init__(self, get_response): self.get_response = get_response self.pages = [] # One-time configuration and initialization. def __call__(self, request): # Code to be executed for each request before # the view (and later middleware) are called. if request.user.is_superuser: match = re.match(r'/admin/', request.path) if len(self.pages) and self.pages[-1] is not None and match is not None: referred = re.match(r'/admin/', self.pages[-1]) if referred is None and match is not None: messages.add_message(request, messages.INFO, 'You must reauthenticate') logout(request) self.pages = [] return redirect('/admin/login/') if request.path[-1] == '/': self.pages.append(request.path) response = self.get_response(request) # Code to be executed for each request/response after # the view is called. return response I have the custom middleware on the python path and have added it to settings … -
'relation "django_site" does not exist' only when running Django tests in GitHub Actions
I have a Django 3.1 project with an Admin class like this really simple example: from django.contrib import admin from .models import Book class BookAdmin(admin.ModelAdmin): def book_title(self, obj): return obj.title admin.site.register(Book, BookAdmin) And I test that class: from django.contrib.admin.sites import AdminSite from django.test import TestCase from myapp.admin import BookAdmin from myapp.models import Book class BookAdminTestCase(TestCase): def test_book_title(self): book = Book(title="Hello") book_admin = BookAdmin(Book, AdminSite()) self.assertEqual(book_admin.book_title(book), "Hello") This works fine when I run tests (./manage.py test) on my local development site. But when I run tests in a GitHub Action step... - name: Run Tests run: | pipenv run ./manage.py collectstatic --verbosity=0 --noinput pipenv run ./manage.py test env: DJANGO_SETTINGS_MODULE: config.settings.tests # etc ...while other tests all work fine, tests using the AdminSite() call fail with: psycopg2.errors.UndefinedTable: relation "django_site" does not exist 196 LINE 1: ..."django_site"."domain", "django_site"."name" FROM "django_si... These tests use the same Django settings as when run locally. If I run migrations in the GitHub Actions step before I run the tests... - name: Run Tests run: | pipenv run ./manage.py collectstatic --verbosity=0 --noinput pipenv run ./manage.py migrate --verbosity=0 --noinput pipenv run ./manage.py test env: DJANGO_SETTINGS_MODULE: config.settings.tests # etc ...this error doesn't occur, so I can get round this, but …
