Updating manytomanyfield unchecks previous objects
My project consists of a Book model which holds all sorts of different genres of books. For example romance, horror, sci-fi and so on. Each user then has a reading list. Which is a model that looks like this: class Readinglist(models.Model): user = models.OnetoOnefie(User, on_delete=models.CASCADE) books = models.ManyToManyField(Books) The reading list is then presented to each user by category. To be able to add books to each category, have I created unique views (the categories are not that many). The horror view looks like this: class UpdateReadingListHorror(UpdateView): model = ReadingList form_class = ReadingListHorrorForm The ReadingListHorrorForm looks like this: class ReadingListHorrorForm(forms.ModelForm): book = forms.ModelMultipleChoiceField(queryset=Books.objects.filter(genre='Horror'),widget=forms.CheckboxSelectMultiple, label='') class Meta: model = ReadingList fields = ['books',] All the other views and forms for the other genres look the same, only the query set in the form is changed to match it. The problem is that when I update the Horror category, the books in the other categories get unchecked and are no longer tied to the user's reading list. I can't understand why this is happening. How can I prevent this from happening? -

Class Based Views Form neither Valid nor Invalid (Django)
I'm new to Django Class Based Views and I can't get my form to pass through neither form_valid() nor form_invalid(). I have taken most of this code from the Django allauth module, so I extend some mixins (AjaxCapableProcessFormViewMixin & LogoutFunctionalityMixin) that I do not know well. This form is meant to allow users to change their passwords upon receiving an email. As it is now, users are able to change their password but since the form_valid() function is never triggered, they do no get redirected to the success URL as is intended. Instead the password change is registered but the users stay on the same page. The functions dispatch(), get_form_kwargs() & get_form_class() are all triggered and behave in the way that they should. Still, it's unclear to me why they execute in the order that they do (dispatch() is triggered first, then get_form_class() and finally get_form_kwargs(). I suppose they implicitely have an order as presented in this documentation: https://ccbv.co.uk/projects/Django/4.0/django.views.generic.edit/FormView/) I am lacking some intuition about how this works, therefore I don't know if there is a way to redirect to the success URL without passing through form_valid() because that would also solve my problem. Here is my code: class PasswordResetFromKeyView(AjaxCapableProcessFormViewMixin, … -

hasattr(value, "contribute_to_class") returns KeyError: 'contribute_to_class' (Django 4.0.6)
A Django 1.1 / Python 2.7 project that I'm attempting to run on Python 3.10 / Django 4.0.6. A Python related error (i.e. old import) or a django code error (i.e. missing field that's now mandatory) pops up, I fix it and rerun. The current error, however, is coming from django/db/models/base.py, from this function - def _has_contribute_to_class(value): # Only call contribute_to_class() if it's bound. return not inspect.isclass(value) and hasattr(value, "contribute_to_class") I found this ticket - https://code.djangoproject.com/ticket/30309 that explains that hasattr is unreliable, but seems to be ignored. Has anyone encountered this issue, and managed to find a solution other than staying on Django 1.1? -

How to filter based on a field in the custom through model using rest serializer?
I have two models with many to many relation. The many2many table is created and linked to the parent tables by the 'through' attribute. ModelA(modles.Model): name = charfield() ModelB(models.Model): subject = charfield(default=1, choices = [1,2,3]) people = ManyToManyField(ModelA, through="MOdelAB") ModelAB(models.Model): status = integerfield() modela_id = foreignkey() modelb_id = foreignkey() ModelB_Serializer(serializers.Serializer): modela = ModelASerailizer(many=True) class Meta: model = ModelB exclude = ... fields = ... depth = 1 This returns all the A objects in the through table, but I want to filter only the ones with status=99. Is there a nice way to do that? -
Django: How to add a foreign key that references itself and also sets a field on the referenced object
Sorry for the terrible title. I'm not even sure what I'm looking for. Basically, I would like to create the following: Model comprised of Ethernet switch interfaces (ex. ge-0/0/1, po4096, etc.) Be able to connect Ethernet switch interfaces TOGETHER (so, a foreign key to its own model) This is what I currently have: class EthernetSwitchInterfaces(models.Model): """ Represents interfaces on switches (ex. ge-0/0/1, ae1001, po1001, xe-1/1/1, eth1/101, etc.) """ interface = models.CharField(max_length=32, blank=False, null=False, help_text='Interface name (ex. xe-1/1/1, eth1/101, po1001, etc.)') switch = models.ForeignKey(EthernetSwitches, to_field='id', on_delete=models.CASCADE, help_text='Switch') # Note the speed of that interface link_bandwidth_in_gbps = models.IntegerField(blank=False, null=False, help_text='Total interface bandwidth in Gbps') # Account for port channel interfaces is_port_channel = models.BooleanField(default=False, blank=False, null=False, help_text='Is this a port channel interface?') number_of_links = models.IntegerField(blank=False, null=False, default=1, help_text='Number of links (if port channel)') switch_to_switch = models.ForeignKey('self', blank=True, null=True, help_text='Switch-to-switch connection', on_delete=models.SET_NULL) def __str__(self): return "{} - {}".format(self.switch, self.interface) class Meta(object): unique_together = ('interface', 'switch',) This almost works. I create an interface, create a second interface, and set the second interface's switch_to_switch field to the original interface. This works great except the original interface has a blank switch_to_switch value. Any help would be greatly appreciated! I've been stuck on this for a week now … -

how do i convert this function based view to a class based view?
i recently created a category system but the problem is that when ever i go to another page that isn't the home page, all the categories go away because i haven't referenced them. i found that by adding def get_context_data(self, *args, **kwargs): cat_menu = Category.objects.all() context = super(CategoryView, self).get_context_data(*args, **kwargs) context["cat_menu"] = cat_menu return context below each view then it would allow the categories in all my pages. but because for a few views i used function based views and since i can't for example do: def CategoryView(request, cats): category_posts = Post.objects.filter(category=cats) return render(request, 'blog/categories.html', {'cats':cats, ' category_posts':category_posts}) def get_context_data(self, *args, **kwargs): cat_menu = Category.objects.all() context = super(CategoryView, self).get_context_data(*args, **kwargs) context["cat_menu"] = cat_menu return context i need to convert def CategoryView(request, cats): category_posts = Post.objects.filter(category=cats) return render(request, 'blog/categories.html', {'cats':cats, ' category_posts':category_posts}) to a class based view. i first tried doing this: class CategoryView(ListView): template_name = 'blog/categories.html' model = Post context_object_name = "category_posts" def get_queryset(self): return super().get_queryset().filter(category=self.kwargs.get('cats')) def get_context_data(self, *args, **kwargs): cat_menu = Category.objects.all() context = super(CategoryView, self).get_context_data(*args, **kwargs) context["cat_menu"] = cat_menu return context but when i rendered out the template i lost the {{cats}} - categories any help would be appreciated -

Django : Adding pagination and searchbar to filter the listing of a FormView (ClassView)
I use a FormView from the ClassView available in Django to upload and display listing of files. In the FormView there is no get_queryset and pagination methods to list easily data. So I used the te get_context_data and the get method combined with a pagination method that I wrote to do my file table listing.This part works I want to add a searchbar to filter the results and change the pagination too. However I do not manage to add this fonctionnality to my code. I think that the code is not well structured between the "get_context_data", "get" and "pagination" and I do not see how to change it. I think the problem is more with how I use the "get_context_data" and "get". Can anyone help me ? There is no interest to look to the post method of the code, it is to upload the files. views.py class DocumentUpload(FormView) : model = Documents template_name = 'upload/upload.html' form_class = FilesForm def pagination(self, page_number, list_files): paginator = Paginator(list_files, 10) try: list_files_page = paginator.page(page_number) except PageNotAnInteger: list_files_page = paginator.page(1) except EmptyPage: list_files_page = paginator.page(paginator.num_pages) return list_files_page def get_context_data(self, *args, **kwargs): # Call the base implementation first to get a context context = super(DocumentUpload, … -

Foreign key relationship with boolean values
I'm working on a feature. I've three different car types (Sedan, Hatchback, SUV): Category(models.Model): id- name- image- I've 6 features in total. Feature(models.Model): id- name- detail- image- Out of 6, 4 features are their in every car. The second car category has 5 and the third has all the 6 features. Here where I'm getting stuck: I've to send all the 6 features in all the categories to the frontend so that if someone clicks on the first category, they should be able to show them all 6 with 2 non-available feature strike down or disabled or something. So basically there should be some boolean value which shows that this feature in this category is True or False. How can I design the tables?
