wrapping password reset confirm url in a href doesn't work
I have a password reset template with the following redirect to a password confirm view: <a href="{{ protocol }}://{{ domain }}{% url 'consumer_portal:password-reset-confirm' uidb64=uid token=token %}">Change password</a> When I click "Change password" on the browser it doesn't work. However I can copy the url on the change password text and paste it in my browser and it will redirect me to change my password. Anyone know why clicking it doesn't work but pasting it in the browser does? For context, my reset confirm template has the standard link check {% if validlink %} <p>Please enter your new password twice so we can verify you typed it in correctly.</p> <form method="post"> {% form %} </form> {% else %} <p>password reset invalid</p> -

Django FastApi 2 servers
Please help me. I have a project on Django, in which some of the processes go through celery. But now I want to transfer all the complex data processing to another server. I plan to use FastApi. But the question arose - how to properly organize the work with the client files that will be processed . Do I need to receive files from the client and save them on the second server, or do I need to save them on the first server and send them over tcp? Perhaps there are other options ? How do I do this ? -

Django prefetch_related and N+1 - How is it solved?
I am sitting with a query looking like this: # Get the amount of kilo attached to products product_data = {} for productSpy in ProductSpy.objects.all(): product_data[productSpy.product.product_id] = productSpy.kilo # RERUN I do not see how I on my last line would be able to use prefetch_related. In the examples in the docs it's very simplified and somehow makes sense, but I do not understand the whole concept enough to see myself out of this. Could I please get explained what's being done and how? I find this very important to understand, and where met by my first N+1 here. Thank you up front for your time. -

Django ORM more than one row returned by a subquery used as an expression

DRF spectacular swagger ui problem when extending a new TokenAuthentication for DRF
when extending a new Token Authentication class from rest_framework_simplejwt.authentication.JWTAuthentication drf-spectacular swagger-ui authorize button disappears and there is no way to add token bearer, I guess when you subclass it goes wrong. steps to reproduce: first, create a Django project with rest framework and drf-spectacular and simple jwt installed and configured with documentation guidance. got to /swagger-ui/ and it works fine. then create a subclass of JWTAuthentication like below: from rest_framework_simplejwt.authentication import JWTAuthentication as JWTA class JWTAuthentication(JWTA): pass and in your settings: REST_FRAMEWORK = { 'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema', 'DEFAULT_AUTHENTICATION_CLASSES': ( 'path_to_your_module.JWTAuthentication', ), } and now if you go to /swagger-ui/ there is no authorize button!!! how can I fix this? and I even tried to create an AuthenticationExtension like: from drf_spectacular.contrib.rest_framework_simplejwt import SimpleJWTScheme class SimpleJWTTokenUserScheme(SimpleJWTScheme): target_class = 'spec.test.JWTAuthentication' but there is no way to register it anywhere nor on the internet nor in the documentation!! how can I fix authorize button when overriding an Authentication class?? -

Template inheritance: Change Nav-Tab active tab and URL with Click on Tab (Django, Bootstrap)
I'm currently designing a Web-App with Django and Bootstrap. I have several HTML files which I want to load dynamically in one "Parent" HTML-file via different URL's. Everything is working so far. My Goal is to use a Tab or Nav-Bar for the Template inheritance. As soon as I click on another Tab, the corresponding URL becomes targeted an the HTML content should open in the selected Tab . I can't manage both at the same time. Either the Tab opens or the new URL is loaded. In the second case the default Tab is active again which is caused by reloading the page. I also tried using a JavaScrip function to load the new URL and afterwards show the corresponding Tab. But no success so far... Im happy with every hint regarding my problem. Thanks a lot -

Accessing inline fields within inline get_formset in Django Admin
I have the following example where I have buildings(address, location,...) and apartments(name, size, type, building). One building containing multiple apartments. class BuildingAdmin(admin.ModelAdmin): inlines = [ApartmentInline,] class ApartmentInline(admin.StackedInline): def get_formset(self, request, obj=None, **kwargs): formset = super(ApartmentInline, self).get_formset(request, obj=None, **kwargs) #Here i'd like to see the values of inline fields, for example size or building that. #Similar to how one can access ModelAdmin fields with obj.location within get_form formset.form.base_fields["type"].widget = SelectMultiple(choices=custom_choices) return formset I'd like to be able to get the current apartments instance and field values when editing the object (for example size), so that I can create custom choices (querying other DB's or API's) for another field (type). -
