Form does not prevent duplicate creation of a compound primary key
I'm trying my first Django project right now and have encountered the problem that my app reacts strangely when I try to create an object with duplicated compound primary keys. The following starting situation: In order to be able to clearly determine my result, I use a composite primary key consisting of a unique student id (matriculation_number) and a unique exam id (exam_id). Here is the corresponding model in my models.py file: class Result(models.Model): # No student should be able to be deleted as long as there are still results to show. matriculation_number = models.ForeignKey(Student, on_delete=models.PROTECT, verbose_name='Matrikelnummer') # No student should be able to be deleted as long as there are still results to show. exam_id = models.ForeignKey(Exam, on_delete=models.PROTECT, verbose_name='Prüfungsnummer') grade = models.DecimalField(max_digits=3, decimal_places=2, default=None, validators=[MaxValueValidator(6), MinValueValidator(1)], verbose_name='Note') # Workaround for composite primary-key # Get Data using Result.objects.get(matriculation_number=”10”,exam_id=”125”) class Meta: unique_together = (('matriculation_number', 'exam_id'),) verbose_name = 'Ergebnis' verbose_name_plural = 'Ergebnisse' To get a composite primary key at all, I use the workaround with unique_together. The following views.py and forms.py parts also belong to it: views.py class ResultCreateView(generic.CreateView): form_class = CreateResultForm template_name = 'studentmanager/result/result_create_form.html' success_url = reverse_lazy('studentmanager:result') forms.py class CreateResultForm(forms.ModelForm): class Meta: model = Result fields = ['exam_id', 'matriculation_number', 'grade'] widgets … -

Django Admin List Filter Remove All Option
As you can see from the screenshot bellow, When using and customizing django admin filters like so: class DealExpiredListFilter(admin.SimpleListFilter): title = 'expired' parameter_name = 'expired' def lookups(self, request, model_admin): return ( ('yes', 'yes'), ('no', 'no'), ) def queryset(self, request, queryset): if self.value() == "yes": return queryset.filter(end_date__lt=timezone.now()) elif self.value() == "no": return queryset.exclude(end_date__lt=timezone.now()) Django will insert an "All" option at any case (which is great for %99 of the times). I want to rename or remove that "All" option as can bee seen in the screenshot -
Django - count up timer
Hey I want to implement a timer which starts if I go to this template: {% block content %} <h3>C-Test</h3> <p>In the following text, some of the word endings have been replaced by a gap. The gap is approximately half of the word, e.g. if you see 3 letters, you need to add another 3-4 letters to complete the word. Try your best.</p> <form action="results" id=results method="POST"> <input type="hidden" name="cTestFormat" value="{{ text }}"> <div class="ctest"> {% csrf_token %} {{ forms }}{{ ende }} </div> <div class="command"> <button type="submit" name="ctest_submit">Submit solution</button> </div> </form> {% endblock %} and ends if I click on the Submit solution button. I want it saved into the POST request so I can return the time in my results.html. This is my results.html: {% block content %} <h3>C-Test</h3> {% csrf_token %} <p>You got {{ richtige }} right!!!!!!</p> <p>But {{ falsche }} wrong :(</p> <p> {{ testresult|safe }}</p> {% endblock %} Ive read that you need some scripting language for a timer but I dont have any experience with it. Is there any other method with django to do this or do I need something like javascript? -
How to deploy a Django app locally on a windows xp machine?
I've got a small python 3 application which I'd like to use on a Windows XP machine. Now, the python shell is not that user-friendly, so I decided to build a GUI for it. I've tried using PyQt (with Qt designer) and TkInter, but I don't like working with them. In search for alternatives, I thought about Django. I've worked on a project with Django once and I like the fact that I can use HTML to format the way the app looks. Oh, and I'm in love with how easy it is to implement the admin functionality. However, it looks like deploying a Django application locally on a Windows XP machine isn't even possible. I've read the most recent Django documentation and it states nothing about doing such a thing. If my question is still vague: I'd like to deploy a Django web app locally to use in a browser like Internet Explorer on a Windows XP machine. The installation should be 'plug-and-play'. The application relies on a csv database, so nothing too fancy there. I don't want the user to have them install Python or other dependensies himself. Ultimately, the user should only have to click on the … -
Django Getting User based on AuthToken
I am setting up friend relationships on a social-media style project. When a user goes to the /add_friend endpoint I want Django to automatically know who the user is trying to add a friend based on the AuthToken they are using. I cannot figure out how to do this. Models: class Friend(models.Model): #static variables for friend_status attribute FORMER_FRIENDS = 0 FRIENDS = 1 A_REQUESTS_B = 2 B_REQUESTS_A = 3 friend_A = models.ForeignKey(User, related_name='friend_A') friend_B = models.ForeignKey(User, related_name='friend_B') friend_status = models.IntegerField def __str__(self): return '%s and %s friendship' % (self.friend_A, self.friend_B) class Meta: unique_together = (('friend_A', 'friend_B'),) URL: url(r'^friend_request/(?P<username>[\w.@+-]+)', AddFriend.as_view(), name = 'add_friend'), Class-Based View: class AddFriend(APIView): def get(self, request, username): user = Token.objects.get(key='token string').user friend = User.objects.get(username=username) #check for friendship instance new_friend, created = Friend.get_or_create(friend_A=user, friend_B=friend) I'm almost certain the trouble is this line: user = Token.objects.get(key='token string').user I don't know what value to enter for the key. The key is unique for each token, and I obviously don't want to hard code a key in there. I have tried removing the key entirely like this: user = Token.objects.get.user But in that case I get the error: AttributeError at /friend_request/brian 'function' object has no attribute 'user' Can someone please advise … -
Unable to Escape \? in Python Regex
This question has been asked many times before. And the answer is all the same: If searching for a literal question mark r'?' then the question mark should be escaped with a backslash r'\?' The problem is that I keep getting this Django Error when I run the command: nothing to repeat at position 0 (line 1, column 1) What have I done wrong in my code? rawcontent = "Im Ron Burgandy? I saw that! Brick killed a guy. Did you throw a trident?

How to define a foreign key based on name when extending a django-oscar model?
I have forked the django-oscar catalogue app to have an additional model, Collection. This is for a furniture site, so the idea is that several products will be part of a collection, which has a name in common with all products. For example, a Bedroom collection might have a nightstand, chest of drawers and bed, all named 'Denver'. My goal in doing this is so that I can display a page showing different collections, and for each collection show all the products associated with that collection. Also that when deleting a collection all associated products are deleted, but not the other way around. This is the model I am using in my forked version of the django-oscar catalogue app: from django.db import models class Collection(models.Model): name = models.CharField(max_length=50) prod_category = models.CharField(max_length=50) description = models.TextField() manufacturer = models.TextField() num_products = models.PositiveIntegerField() image_url = models.URLField() from oscar.apps.catalogue.abstract_models import AbstractProduct class Product(AbstractProduct): collection = models.ForeignKey(Collection, on_delete=models.CASCADE, null=True) multiplier = models.DecimalField(max_digits=2, decimal_places=1, default='2.2') from oscar.apps.catalogue.models import * My concern is that, by setting the foreign key as I have, django automatically creates a collection_id field, but each product is not tied to a collection based on any criteria. I would like to use the … -

Wagtail streamfield on frontend (architecture question)
I'm about to start a little side project and discovered wagtail cms. The main idea is to create a web project which is about sharing information with others. I thought i could use the wagtail streamfield on the frontend, to make it easy for all users to create content. But it appears to me that streamfields were not designed for this purpose. The alternative would be a text area with tinymce. Users would hand in submissions for review. In the wagtail backend I would convert the submitted text to streamfield input. But this would generate too much overhead. Would it be wise to use plain django for this? The site is going to rely heavily on user generated content. Maybe I'm missing something but is wagtail designed for what I intend to do? Any advice would be much appreciated. -

Django APIView to log out of a user session
I have a Django module which is called from an SSO service. The service has a single signout function which makes a single GET request to a URL given to it during login. I'm trying to set up an APIView in Django to handle this logout. The origin service never checks the response; it only calls the GET URL once. I'm trying something like this for the APIView but keep getting session.DoesNotExist exceptions: class LogoutApi(APIView): def get(self, request, *args, **kwargs): s = Session.objects.get(session_key=kwargs.get('sk', '')) s.delete() return Response({'result': True}) I know I have a valid session but even when I try iterating through the Session.objects I can't find it. I also tried pulling the key from the SessionStore: class LogoutApi(APIView): def get(self, request, *args, **kwargs): sk = request.GET.get('sk', '') try: s = SessionStore(sk) del s[sk] return Response({'result': True}) except: self.logger.error(sys.exc_info()[0]) return Response({'result': False}) It still wasn't successful. Is there a way I can set up a GET API call to terminate a specific session? -

So I thought it would be a good idea to separate documentation for each type, i.e urlpatterns += [ url(r'^/admin/swagger/$', admin_schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'), url(r'^/app/swagger/$', app_schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'), ] So it looks as though drf-yasg supports this, via supplying patterns into the get_scheme_view: admin_schema_view = get_schema_view( openapi.Info( title="API", default_version='v1', description="The set of API endpoints used.", terms_of_service="https://www.google.com/policies/terms/", contact=openapi.Contact(email="contact@me"), license=openapi.License(name="BSD License"), ), patterns=?????, validators=['flex', 'ssv'], public=True, permission_classes=(permissions.AllowAny,), ) Now my guess was to supply a string, the same way as the first string when defining urls, such as patterns=r'^admin/v1/', which results in: File "/usr/local/lib/python3.6/dist- packages/rest_framework/compat.py", line 55, in get_original_route return urlpattern.regex.pattern AttributeError: 'str' object has no attribute 'regex' So with the documentation at drf-yasg docs: patterns – if given, only these patterns will be enumerated for inclusion in the API spec Exactly what type of object is needed here in order for to process patterns? I've tried looking around the django-rest-framework and Django source code on github, but couldn't find what type is actually needed, they are both …
