How to pass choises from views.py in forms.ChoiceField?
I want to make a form for online tests, but I can't figure out how to make radio buttons (forms.ChoiceField or similar) with the transfer of the selection value not from forms, but from views. Why can't you get from models directly in the form? because I do not know in advance which pk is needed. Please tell me an option that will help you create a form for online testing. I ask with examples to make it easier to understand. Thanks in advance. -
Reverse for 'bans' with keyword arguments '{'user': 1}' not found. 1 pattern(s) tried: ['bans/(?P<pk>[0-9]+)/$']
I am building a GroupApp and I am trying to add some group members in premium_members(ManyToManyField). In Brief :- I made a Group model for group creation and adding members and I made another GroupPosts with ForeignKey of Group for post creation in the particular Group with id or pk. It means i am accessing all the groups in one page and when someone opens a group then blogposts are showing of the clicked group, Like group_1 has 6 posts and group_2 has 2 posts. AND I am trying to add post_creater in premium_members which is a instance in Group Model. The Problem :- BUT When i click on add_premium_member in the group's post's User. Then post creater is not adding in premium_members. No error is showing. BUT NOT ADDING. models.py # For Group Creation class Group(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=30,default='') premium_members = models.ManyToManyField(User, related_name='premium_members', blank=True) def get_absolute_url(self): return reverse('group_detail_view',kwargs={'pk':self.pk}) # For Post Creation in Particular Group class GroupPosts(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) group = models.ForeignKey(Group,on_delete=models.CASCADE) post_title = models.CharField(max_length=30,default='') views.py # For show the group details and posts in one page (group_detail_view) def group_detail_view(request,pk): data = get_object_or_404(Group,pk=pk) posts = GroupPost.objects.filter(group=data) context = {'data':data,'posts':posts} return render(request, 'group_detail_view.html',context) # … -
How to access a legacy database without creating a new table in it in Django
I was given access to a database to use on one of my Django projects. I set everything up and went to migrate the new models and I got an error. "Unable to create the django_migrations table ((1142, "CREATE command denied to user 'MyDatabaseName' for table 'django_migrations'"))" After looking into it, I see its because Django is trying to create a new table in that database. I don't have write access and I do not want it because I am pretty new at this and do not want to mess anything up. I am also not sure the owner would give it to me. Is there a way to get to use the legacy database without having to create a new table in it? -

Customizing model fields by user
I am making a CRM, and I ran into one task: I want to make a “Client” model, with all possible fields, and give an opportunity for users to “enable” only those “Client” fields that he needs. I have little experience and unfortunately I have not been able to find a solution for this for a long time. I would be grateful if someone can show me an example of how this is done (or a link to a repository with a similar method). -
Setting Up Logins For Users with Django
I am trying to use Django's built in user authentication for login/allowing users to create an account and login. I think there's something wrong with my urls or where files are placed in the project. Can anyone help? I know the login.html file is supposed to be inside a folder called 'registration.' I think the fact that my templates are then in a sub folder called 'capstone' might be causing issues. I just don't know how to point to the right file when someone clicks to login. In urls.py under 'weather' I have the following. In two tutorials I saw it should say 'accounts/' but I'm a bit confused as to why. urlpatterns = [ path('admin/', admin.site.urls), path('', include('capstone.urls')), # medium site says to do this path('accounts/', include('django.contrib.auth.urls')), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) This is how my files are set up in Visual Studio Code: -

How can I convert/export HTML code returned by django-ckeditor's RichTextUploadingField to a docx file?
I want to convert html received from django-ckeditor Field to a docx file, for which I'm using htmldocx. The html code returned by ckeditor uses a css file which contains styles like background-color. So htmldocx is able to recognise bold, italics and alignment but it is not recognising the highlight color. contents of views.py: def home(request): if request.method == 'POST': htd = HtmlToDocx() document = Document() htd.add_html_to_document(request.POST.get('file'), document=document) document.save(settings.MEDIA_ROOT+'TEST.docx') form = File() return render(request, 'home.html', {'form': form}) else: form = File() return render(request, 'home.html', {'form': form}) contents of models.py: class Document(models.Model): file = RichTextUploadingField(blank=True,null=True) For example: for submitted text "Hello World" , where say 'World' is both, highlighted and in italics, the html code returned is: <p>Hello <em><span class="marker">World</span></em></p> #styles of marker class are defined in a separate css file by ckeditor but upon converting the html to docx, the document loses highlight color. Is there any workaround to this issue? Also, ckeditor provides an export to word feature but only through npm. If somehow I could use that feature in django-ckeditor, things would become much easier. How can I implement that feature in django-ckeditor? -
Why do I get an 404 Error in part 4 of the Django tutorial "Writing you first Django app"
I am trying to complete the Django tutorial: Writing your first Django app. I am currently stuck on part 4. After updating my template polls/templates/polls/detail.html, rewriting my polls/views.py and creating a results.html located at polls/templates/polls/results.html, I ran the server and tried to go to http://127.0.0.1:8000/polls/1/, but I get this Error: Page not found (404) No Question matches the given query. Request Method: GET Request URL: http://127.0.0.1:8000/polls/1/ Raised by: polls.views.detail Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: polls/ [name='index'] polls/ <int:question_id>/ [name='detail'] The current path, polls/1/, matched the last one. You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

Django form validation fails when dynamically creating form by overwriting __init__
I'm writing a prediction app in Django. At a basic level it pulls matches from an API, populates the database, and finally allows users to make predictions on matches that have not yet been played. As I don't know how many matches will be in a tournament before the fact, I wanted to create a form that dynamically adds as many fields as is required. I currently have a "working" version but it would create issues further down the line. Here's the working version: (Fair warning, this is me testing, so excuse the naming conventions) views.py def ftest(request, contest_id): matches_list = Matches.objects.filter( matches_contest_pk__id = contest_id ).filter( matches_complete = False ).order_by( '-matches_start_time' ) matches = [ f'{match.matches_team_1} vs. {match.matches_team_2}' for match in matches_list ] if request.method == 'POST': form = TestForm(form_fields = matches, data=request.POST) if form.is_valid(): return HttpResponseRedirect('/thanks/') else: print(form.errors) else: form = TestForm(form_fields = matches) context = { 'form': form, } return render(request, 'predictions/test.html', context) forms.py from django import forms from .models import Matches class TestForm(forms.Form): def __init__(self, *args, **kwargs): form_fields = kwargs.pop('form_fields', None) super(TestForm, self).__init__(*args, **kwargs) for field in form_fields: self.fields[field] = forms.CharField(label = f'{field}', max_length = 100) As I said, this works but I would, ideally, like to … -

Django Displaying Each User's Profile
I am building a website where there is a table at the homepage, and in that table there are people's names, numbers, their categories, the city they reside in, etc. I would like to create a link, that when a visitor clicks on any of the users' name, the visitor gets directed to that specific user's profile page. Right now, my code works partially. When I click any user, I get redirected to http://127.0.0.1:8000/profile/7/. That user ID number of "7" is the logged in user's ID. So no matter which user I click on, I get redirected to the profile page of the logged in user. Also, when I log out of the current user I am logged in to, I get this error message: "NoReverseMatch at / Reverse for 'profile_pk' with keyword arguments '{'pk': None}' not found. 1 pattern(s) tried: ['profile/(?P[0-9]+)/$']" Here is what I have done with my code so far: views.py def ustaprofil(request, pk=None): if pk: user = get_object_or_404(User, pk=pk) else: user = request.user args = {'user': user} return render(request, 'user.html', args) urls.py path('profile/<int:pk>/', views.ustaprofil, name='profile_pk'), models.py class Usta(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) gizlilik_sozlesmesi = models.BooleanField("Gizlilik Sozlesmesini Okudum Onayliyorum*" , null=True) sartlar_sozlesmesi = models.BooleanField("Sartlar ve Kosullar … -
Best way to store heavily related values in relational database
I am trying to efficiently store heavily related data in a relational database. Table A stores the field names. Table B stores the type and Table C stores the values. I came up with the structure and the mappings as shown in this figure: Now when I want to query data from this table, we have to perform 2 hits for each relation. Also, for every insert I need to hit DB thrice(one for each table). Is there a better way to store this kind of structure? Is there a standard way to save this in Django models? -
Django path converter raises SynchronousOnlyOperation
I'm migrating an existing WSGI server to ASGI and I'm running into a problem where ORM usage in path converters raises a SynchronousOnlyOperation exception. My converter code is something like this class ModelPkConverter: regex = r'\d+' model = MyModel def to_python(self, primary_key): try: return self.model.objects.get(pk=primary_key) except self.model.DoesNotExist: raise ValueError def to_url(self, instance): return f'{instance.pk}' So when I go to a URL like /myapp/<MyModel:my_model>/ I get django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async. Where exactly am I supposed to put sync_to_async? If I do it in the converter like this @sync_to_async def to_python(self, primary_key): ... The converter outputs a coroutine object instead of a MyModel instance so I get AttributeError when I attempt to use it. AttributeError: 'coroutine' object has no attribute 'my_attribute' Am I supposed to await it in the view? That would defeat the purpose of using converters. I can just do get_object_or_404 instead. Is there a solution that doesn't involve setting DJANGO_ALLOW_ASYNC_UNSAFE to True? At this point, I'm considering refactoring everything away from the converters and using <int:mymodel_id> everywhere instead. Is there another way? -
