Cannot display foreign key in Django list view
I'm trying to display the foreign key information in my list view for the primary key and it's just not displaying and I cannot for the life of me figure out why.

HTMX: How to update hx-delete url dynamically?
In order to build a modal to confirm a delete action, I'm trying to dynamically set a delete url, using hyperscript. Here is the (partial) code: <!-- open the modal and set the (Django) delete url --> <button _="on click set @hx-delete of #confirm_delete_button to '{% url view_name record.pk %}'"> <!-- the delete confirmation button --> <button id="confirm_delete_button" hx-delete="to_be_set_later_by_hyperscript" hx-trigger="click" hx-target="body" {# TODO: change #} hx-swap="delete"> Delete </button> At first, everything seems to work as expected, since I can see the right delete url in the inspector: However, when clicking the button, I got a Not Found: /to_be_set_later_by_hyperscript error, showing that even if the attribute has been set, the "old" url is used by HTMX. What should I do? Thanks. -

when set up reload-on-rss in uwsgi server , how to avoid all processes reload/respawn at the same time?
I'm encoutering a situation that using reload-on-rss/reload-on-as = 256 to avoid memor leak, it works for almost all scenes. however, by setting up these params, there's a extremely small probability that all processes are running out of memory which been set. so they'll all respawn at the same time, and I found out rest requests responded in 502. So I wanna ask if there is a way to keep at least one worker running to process requests even its memory usage's exceeded (it should not reload untill another worker started)? I've tried searching for the settings to make it but cannot found anything. does anyone can help? thank you so much!

Registering a function in Django
I have a very simple python script that runs Tanimoto similarity index between a molecule sample and a molecule database: from openbabel import pybel targetmol = next(pybel.readfile("smi", "/path/to/sample.smi")) targetfp = targetmol.calcfp() <--- calculate fingerprints of the sample for mol in pybel.readfile("smi", "/path/to/db.smi"): fp = mol.calcfp() <--- calculate fingerprints of the db tan = fp | targetfp <--- calculate the Tanimoto index via the "|" operator if tan[0] >= 0.8: print(tan) My goal here is to add this function to a website that I am developing with Django. Ideally, users will submit their own molecule and receive a list of the most similar ones present in my database on a new page, as an on-click function. What I need to do here is to let the script use the users's molecule as a sample but, most importantly, I do not know how to deploy this function in the Django framework. Since I know that this is not a code shop, I simply would love to receive a clear explanation on how to register my function, how to call it as an on-click function and what I have to change in order to let the script use the users's molecule instead of … -
Pagination in Django ListView when using get_context_data
I am currently facing this problem with Django ListView. Basically, I need to filter some questions per topic and I would like to paginate the results. My code is working perfectly about the queryset part (the results are showed correctly) but I am facing a problem with pagination. Let's say I have so far 8 items in my query, if I choose to paginate_by = 10, it shows me just one page. If, otherwise, I choose to paginate by, let's say, 3, it shows me 3 pages to choose in the template (which is correct) but it shows me ALL the results of the query in my page. I post some code to be more clear models.py: class Tag(models.Model): name = models.CharField(max_length=300, unique=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def clean(self): self.name = self.name.capitalize() def __str__(self): return self.name class Question(models.Model): post_owner = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=5000, default='') body = tinymce_models.HTMLField() tags = models.ManyToManyField( Tag, related_name='tags') viewers = models.ManyToManyField( User, related_name='viewed_posts', blank=True) views.py: class TagQuestionsListView(ListView): template_name = 'main/tag_questions.html' paginate_by = 20 def get_queryset(self, **kwargs): tag = Tag.objects.get(name=self.kwargs['name']) questions = Question.objects.filter(tags=tag) return questions def get_contextdata(self, **kwargs): context = super().get_context_data(**kwargs) context['tag'] = Tag.objects.get(name=self.kwargs['name']) context['questions'] = Question.objects.filter( tags=context['tag'], is_deleted=False) return context template: {% … -

Rescalling image that isn't called specifically as an image in HTML
This is going to be a very novice question. I am working with a Django application and for the first time I am having to edit the HTML, something I haven't worked on in years and even when I did I was not a high level. The current code has something like the following written: <div class="x"> %(image)s </div> I have never seen this '%(image)s' syntax before and anything I google appears to refer to string substitution and things like this. The class also has a max width of 16.6667% but the image does not rescale to this width. I have tried to add in widths to the div but with no luck and I believe it may be due to the way the image is being fed through to the html. Any insight on what an earth is happening here so I can find where the image is defined and potentially generate a smaller one at that stage would be much appreciated. -
Wagtail - how to make user management work with User.is_active being a @property?
Making the User.is_active flag a python @property instead of a read database field results in the following error: django.core.exceptions.FieldError: Unknown field(s) (is_active) specified for User class User(AbstractBaseUser, PermissionsMixin): @property def is_active(self): return .... This is because wagtail.users.forms.UserEditForm included "is_active" in the fields: class UserEditForm(UserForm): class Meta: model = User fields = {User.USERNAME_FIELD, "is_active"} | standard_fields | custom_fields This error occurs as long "wagtail.users" is included in settings.INSTALLED_APPS, even when overriding the default forms as described in the documentation. WAGTAIL_USER_EDIT_FORM = 'users.forms.CustomUserEditForm' WAGTAIL_USER_CREATION_FORM = 'users.forms.CustomUserCreationForm' I tried to disable the wagtail user management entirely, but this does not seem to be possible. https://github.com/wagtail/wagtail/issues/3657 Any ideas how to make this work? -

Django-Template based navigation and project structure
I am working on a Django project that is based on some common data structure but the data needs to be populated through different forms. For example WebForm_1 is based on Template_1 layout and logic, while WebForm_2 is based on Template_2 layout and logic. Yet data will be saved to the same database table. This concept applies to all forms that will be a part of the web application. So in order to achieve this, I am thinking of having a landing page which will have some brief information for each template. The navigation, home page and subsequent pages will be based on this template choice. 1) Is this the correct way of designing the project? 2) What would be the best and secure way of passing the template choice to ensure all CRUD is for that template only? Thanks -
