Django check_token(user, token) fails in view but works in test/shell_plus?
Getting the strangest behavior. This fails in normal Django code (view): user = User.objects.get(...) uid = urlsafe_base64_encode(force_bytes(user.pk)) token = default_token_generator.make_token(user) print("CHECK TOKEN:", default_token_generator.check_token(to, token)) # this prints True! send_email_function(user, uid, token) # When using password reset email, token is denied Then when using the token to reset password, the password reset view claims the token is invalid. If I make a management command that calls the same code to send a password reset email: the token works! This works in shell_plus, same code basically: >>> from django.contrib.auth.tokens import default_token_generator >>> from django.utils.encoding import force_bytes >>> from django.utils.http import urlsafe_base64_encode >>> user = User.objects.last() >>> token = default_token_generator.make_token(user) >>> default_token_generator.check_token(user, token) True I've printed out the SECRET_KEY in each case and that seems fine. Inspecting the make_token function has lead me to trying to set a password and last_login which have not helped. Very confusing! -

Django set Boolean to False when clicking a button
The following code (just to learn Django) allows to mark the user's ticket as "Solved" with an HTML button. When the button is clicked, ticked_solved is set to True, ticket_waiting is set to False. This is also recognized in the template, which I have tested. But then in the dashboard the object would have to change to False/True as well, which as you can see in the screenshot is not the case. I do all this with a form, which is probably not the smartest option either. \\ models.py class Ticket(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, default=None, null=True, on_delete=models.CASCADE, ) title = models.CharField(max_length=200) description = models.TextField() ticket_waiting = models.BooleanField(default=True) ticket_solved = models.BooleanField(default=False) def __str__(self): return str(self.title) \\forms.py class TicketSolved(forms.Form): delete = forms.CharField( label='', max_length=0).widget = forms.HiddenInput() \\views.py def ticket_system_view(request, id): obj = Ticket.objects.get(id=id) form2 = TicketSolved(request.POST) if request.method == 'POST': if form2.is_valid(): obj.ticket_waiting = False obj.ticket_solved = True return render(request, 'ticket-system.html', {'obj': obj, 'form2': form2}) \\ .html {% if obj.user != request.user %} <p>Page Not Found</p> {% else %} <p>Ticket ID {{obj.id}}</p> {{ obj.title }} {{ obj.description }} {% endif %} <br></br> <form method="POST"> {% csrf_token %} {{ form2 }} <button type="submit">Status to Solved</button> </form> ----Just to test if it works: … -

Django : If if-statement ist True -> Don't render the rest possible?
Hello for last time today, Is it possible to say that if the first If statement is true, then I don't want to render the rest of the content? Example below, if for example it is true that the user who is on the page is not the owner of the object, then "Page Not Found" is output. {% if obj.user != request.user %} <p>Page Not Found</p> {% endif %} {{ obj.title }} {{ obj.description }} In this example the if statement matches. But the rest of the content is rendered as well, of course. So that this is not the case, I would have to put everything as {% else %} in the If statement (or the other way around). Then the whole content would be in an If statement like so {% if obj.user != request.user %} <p>Page Not Found</p> {% else %} <p>Ticket ID {{obj.id}}</p> {{ obj.title }} {{ obj.description }} {% endif %} So my question: Can I say that if an If statement is true, the rest will not be rendered? -

How to get a derived class instance in a method of an abstract base class without explicit derived class importing in Django
End goal: I'm creating an abstract base class HierCachedModel(django.models.Model). It's purpose is to perform the overhead needed to maintain an otherwise persistent database cache of a series of functions that reside in 4 Model classes that are hierarchically related. Basically, it saves a cached value anytime any "cached function" in that class is accessed and it over-rides Model's save() and delete() methods to perform cache-related overhead operations such as a cascading deletion of all cached values under the "root" model instance. It also has a set of utility methods that can be called to perform "global" cache-related operations (like fill in missing cached values or delete all caches under a given set or root model objects). Everything works fine, except that the way I did it (and I'm sure it's simply from inexperience), I have to import the derived classes in the abstract base class file I created (hier_cached_model.py) or else I get errors about undefined classes whever I perform anything that traverses the hierarchy. Prior to this caching implementation, I had these classes (I'll do 3 classes as an example to simplify it): models.py: class Animal(Model): ... class Sample(Model): animal = models.ForeignKey(... related_name="samples") ... class Analysis(Model): sample = models.ForeignKey(... … -
how to make a dropdown selection in a CreateView field- Django
i'm adding a new field(location) to my PostCreateView and I want to be able to select that field if it's already in the database. (like idk New York) it does show up but obv its not a dropdown. views.py class PostCreateView(LoginRequiredMixin, CreateView): model = Post fields = ['title', 'content', 'location'] success_url = '/' models.py class Location(models.Model): location = models.CharField(max_length=100) def __str__(self): return self.location def get_absolute_url(self): return reverse('home') class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() location = models.CharField(max_length=100, default="") def total_likes(self): return self.likes.count() def __str__(self): return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk}) I've tried to add this widgets= { 'location': forms.Select(attrs={'class': 'form-control'}) } right underneath to my class PostCreateView, but I guess it doesn't work since I don't use forms.py and instead I use class PostCreateView inside of views.py -
Django Admin's change list view: display image from ImageField
I'm trying to display each model's image in the admin 'change list view' by 1) defining a method that displays an image from an ImageField; 2) inserting it in list_display in admin.py. So far, I've gone through many questions and I've seen many solutions involving format_html. This is what I've come up with: [models.py] class MyClass(models.Model): ... def show_photo(self): return format_html( "<img src={}>", 'self.photo.path' ) [admin.py] class CustomClass(admin.ModelAdmin): ... list_display = ('name','email','show_photo') But, no matter what, I get from Chrome this error: Failed to load resource: the server responded with a status of 500 (Internal Server Error), and the image is obviously broken. It's like format_html() is unable to find my files. I DO manage to display images in admin pages, though: if instead of providing a path such as self.photo.path to src in format_html(), I provide a web url, like http://imageserver.com/images/12345, or; through overriding methods like change_list or changelist_view and then inserting a {% static %} tag in the corresponding template, providing the image's absolute path with object.photo.path. Example: [admin.py] class... ... def change_view(self,request,object_id,form_url='',extra_context=None): p = MyClass.objects.get(id=object_id) extra_context = extra_context or {} extra_context['p'] = p.photo.path return super().change_view(request,object_id,form_url,extra_context=extra_context) [change_form.html] ... </ul> {% endif %}{% endif %} <img src="{% static p … -

Django, Celery and Sequential Asynchronous tasks
I am building a system in Django that uses Celery and Django-Celery-Beat to run data creation and extraction tasks. I am pulling records from a datastore using it's API and from this creating multiple jsonl files as the final output - these files become the basis for all the subsequent tasks. Then images are made using information from the jsonl files and then these files are used to update other systems (namely Solr). All this works fine. It's the Celery part that has me stummped. These tasks need to be run sequentially and they each can't fail, and if they do the sequence needs to stop. I also need to lock the tasks from running twice as this will mess up the jsonl files, image creation, etc.... What I have looked into is using Celery and chains with immutable signatures, as the tasks don't return anything, they create files, images, etc.... But I can't seem to find a method to lock the tasks from running twice at the same time. So the questions has two parts What is the best method for running periodic tasks in Django that needs to run asynchronously but also sequentially within that task? Is Celery … -

Django rest don't see json data of GET XmlHTTPRequest
Recently, i have started playing with django rest framework, my goal is to perform a GET on a rest api with some kind of filtering. For this i have choose to pass filters params as json object. I do this with xmlhttprequest. The problem is the django side don't see my json data when i dump the request. I have try this method with curl and it is ok. But from code, it is not. I have dumped the http headers and see that the only valuable diff is that Content-Length is not set with xmlhttprequest, contrary to curl. I have tried to set it manually but it is refused by javascript engine, he say 'Refuse to set dangerous header', after digging into the internet, this look to be forbidden. I have tried to change to the POST method, and this time, it work, i see my filters data. So my question is, is there a settings, decorator, flag or whatever that can force httprequest to parse content data h when content-length is absent for GET request ? Thanks -
How to paginate different objects of the same endpoint in Django Rest Framework?
Lest supose that I have a model named Collection. I can create a collection, this collection have two important fields: share_with_company, share_list. class Collection(models.Model): name = models.CharField(max_length=200, blank=False, null=False) share_with_company = models.BooleanField(default=False) share_list = ArrayField(models.CharField(max_length=15), null=True, blank=True) owner = models.CharField(max_length=200, blank=False, null=False) currently I have an endpoint: /collections and this endpoint need to return something like it: { shared_with_company:{collections: ..., count: 5} shared_list:{collections: ..., count: 12} my_collections:{collections: ..., count: 20} //dont shared with anyone, created by the current user } but, in the frontend the user want to paginate just my_collections or just shared_list or shared_with_company. I like performance, so should I create a specifics endpoints to each type of collections? But, everytime the user load the collections page will show 12 (max per page) collections of each (my_collections, shared etc.), and then he will be able to paginate it. I don't know if this is the best way to do it, I think a lot of users send 3 requests everytime the page is loaded. Another approach: use an endpoint to load the initial page, and this enpoint will make one request to the first page and the paginations will be made with differents endpoints. I really don't know … -
Django displaying each object in a button
Good day, I have a page to test where tickets are created and where all created tickets (titles) are listed. Now you should be able to click on the title of a created ticket. The button then redirects to an extra page where all the information of the specific ticket is. I've always had trouble displaying user specific stuff, so what needs to be done so that the href="" of each link redirects in HTML to the specific ticket? I did the following \\forms.py {% for i in request.user.addtitle_set.all %} <div> {% if i.user == request.user %} {{ i.title }} {% endif %} <form action="{% url SOMETHING_HERE i.id}" style="display: inline"> <button type="submit">Delete</button> </form> </div> <br /> {% endfor %} \\urls.py path('dashboard/user/ticket', ticket_view), path('dashboard/user/ticket/<int:id>/', ticket_system_view, name="view_ticket"), \\ models.py class Ticket(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, default=None, null=True, on_delete=models.CASCADE, ) title = models.CharField(max_length=200) description = models.TextField() creator_adress = models.GenericIPAddressField(null=True) start_date = models.DateTimeField(default=timezone.now) def __str__(self): return str(self.title) \\views.py @login_required def ticket_view(request, id, *args, **kwargs): try: obj = Ticket.objects.get(id=id) except Ticket.DoesNotExist: return redirect('/') if request.method == 'POST': form = TicketForm(request.POST, instance=Ticket(user=request.user)) if form.is_valid(): obj = form.save(commit=False) obj.creator_adress = get_client_ip(request) obj.save() return redirect('/dashboard/user/ticket') else: form = TicketForm() return render(request, 'ticket.html', {'form': form}) def ticket_system_view(request, id, *args, … -

However, when I run the same MySQL commands locally, I get exactly the same list of tables. And when I run the Django app locally there are no errors. I checked the names Django is automatically assigning the tables on the server and locally using the shell: ModelName._meta.db_table In both cases, this returns: 'exampleAppName_modelname', which leads to my question. What I'd like to know If the 'db_table' name auto-assigns the … -
