how to filter objects to get the sum of the repeated values in Django?
models.py name = models.ForeignKey(CustomUser) date = models.DateTimeField() orders = models.IntegerField(default=0) this is the model which counts daily orders of a user. the order which is made in the same day will just increase the orders count by one. So how to make a query or serializer which gives the result of users with their total orders of all time eg: [{name:albert, orders:35}, {name:Vncent, orders:35}, {name:john, orders:35}, {name:dion, orders:35}, {name:aoidi, orders:35},] -
django count ids in every subgroup
I have models of subjects, topics and questions structured as following: class Subject(models.Model): subject = models.CharField(max_length=200, unique=True) class Topic(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE) topic = models.CharField(max_length=200, blank=False) class Question(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE, topic = ChainedForeignKey( "Topic", chained_field="subject", chained_model_field="subject", show_all=False, auto_choose=True, ) Now I want to create a query that will count ids for each subject, topic. viz: ╔═════════╤═══════╤═══════╗ ║ subject │ topic │ count ║ ╠═════════╪═══════╪═══════╣ ║ 1 │ 1 │ 10 ║ ╟─────────┼───────┼───────╢ ║ 1 │ 2 │ 11 ║ ╟─────────┼───────┼───────╢ ║ 2 │ 3 │ 5 ║ ╟─────────┼───────┼───────╢ ║ 2 │ 4 │ 4 ║ ╚═════════╧═══════╧═══════╝ So far tried the following: numberq=Question.objects.all().values('subject','topic').annotate(TotalQuestions=Count('topic')) numberq=Question.objects.all().values('subject','topic','id').order_by('subject','topic') numberq=df.groupby(['subject','topic'])['id'].count()#.size() Unfortunately nothing yielding expected results. Can someone please guide? As a bonus 🙃 I also want to replace the subject_id and topic_id by the respective name fields. -
Django Avatar Library ValueError
Django has added an Avatar Library to make it easy to install User Avatars: https://django-avatar.readthedocs.io/en/stable/. However I'm lost on: 3: Add the avatar urls to the end of your root urlconf. Your urlconf will look something like: urlpatterns = [ # ... path('avatar/', include('avatar.urls')), ] I want to add the ability for the user to change an avatar on the "profile".html page. path("profile/<str:username>", views.profile, name="profile"), How can I do this? 4: Somewhere in your template navigation scheme, link to the change avatar page: <a href="{% url 'avatar_change' %}">Change your avatar</a> When I add step 4 to the profile page, I get a ValueError: not enough values to unpack (expected 2, got 1). I have not specified a User Avatar yet, but the ReadMe documentation doesn't specify how to set a default avatar image. Thanks so much. I am expecting users to be able to add/change their avatar images. -
Why is my Django web page refusing to load? (View pulling from large mySQL table)
I am currently trying to load a web page which is a table of contracts data that is pulled from a mySQL database. There are a large amount of contracts (210,000+) in the contracts table and it will continue to grow by the thousands daily. As you will see, I have already added pagination, and I have changed the model call to only request columns from the table that are needed to display the information on the webpage. I cannot get the view to load, and I think that it is due to to large size of the contracts table that I am pulling information from. In a separate view, I calculate a similarity array (similarity_arr) and save it as a JSON object in another table in the database, which it is then paired with the user's id as a foreign key. The similarity array is an array which matches the length of the amount of contracts in the contracts table. These contracts are pulled and ordered by the dates they were posted to maintain order which is used to pair the similarity scores to the proper contract in the following view function. The similarity score is just a float … -

DRF serializer validation depends on format of request?
I tried to google this one up and still cannot find an answer. Maybe I am missing sth basic... While testing a PUT and POST requests with pytest I have noticed that when I provide data with a missing serializer field it is ok - as long as I don't specify the format of the request. The code is simply: class MySerializer(CustomModelSerializer): a = ... b = .... c = serializers.BooleanField(source='some_c') def test(): ... data = {'a': something, 'b': something_else} # 'c' is missing, c should be boolean resp = client.post(reverse('articles-list'), data=data, format='json') ... and I get HTTP 400, {'c': [ErrorDetail(string='This field is required.', code='required')]} when I omit the format part though, the test passes... -
Django redirect not clearing after clearing, disabling cache, etc
I have a maintenance mode on my site which I typically turn on while I make changes. It checks if an IP address is in a list of verified IPs, and if it is not, it redirects to a maintenance page. When I finished working on my site I turned maintenance mode back off. Unfortunately, the home page (and, weirdly, only the home page) still appears to redirect to the maintenance page! To fix this problem, I first tried to disable the cache in my browser. Still redirecting. Then I cleared my cache and all of my cookies. Then, to my astonishment, I saw that it was still redirecting in different browsers. What the heck? Then I decided what the heck, and commented out the maintenance mode code from my middleware. Exact same behavior. Then I tried setting up another redirect that would take you from the maintenance page back to the home page, in hopes it would resolve my issue. Turns out this was a bad idea, because now home redirects to maintenance and maintenance redirects to home, so I get a too many redirects error. I tried to just take that part of the code back out, but … -
Why abort() in celery is setting all fields to null?
I have Django application where I am using celery to run asynchronous tasks. The task goes through list of websites and get some data. Inside this task I am using raise Exception inside while loop. Below is my APIView I am using to stop celery task in React. Revoke() does not work at all and this is the only working way to stop my task. class StopTaskResult(APIView): def get(self, request, task_id): AbortableAsyncResult(task_id).abort() return Response({"msg": "Task has been succesfully stopped"}) The problem I am facing is that when the task status is set to ABORTED all fields except task_id are set to null. Once they reach to Exception they are changed to FAILURE and all values are restored. How to change this behaviour? The most important is to keep periodic_task_name and worker fields (even if task status is equal to ABORTED)? -

Django - Query on overridden save() method cached or something
I am overriding the default save() method of my model in Django 4. The problem is that I am making queries related to an instance of the model with the overridden save() method, but the queries seem not to be updated during the method execution. Example: class Routine(models.Model): exercises = models.ManyToManyField(Exercise) def save(self, *args, **kwargs): e = self.exercises.all() # 3 exercises returned super().save(*args, **kwargs) # I call to super deleting 1 exercise and adding a new one e = self.exercises.all() # same 3 exercises returned, not updated with the previous save() call Once all the code has been executed the routine.exercises have been properly updated, the problem is that I am not being able to get this query updated during the save() override. -

In Wagtail, how to prevent page deletion by editors, or set a minimum number of pages of a kind
The site we developed has 2 type of pages, let's call them... "Static" ones: Home, Contact, About us, the general Catalog page, the general Blog page... "Dynamic" ones: each Collection in the catalog, each Blog entry. We, as developers, provide the final customer with all the structure for the Static ones, meaning they don't have to create them at all. There are many reasons for it but mainly because the site structure counts on these pages to always exist (in a Published state btw, but let's leave that aside). And we let and teach the client's editor to do, among other stuff.. Just edit the existing "static"pages. Create, edit and delete child pages in Catalogue and Blog. But we want to prevent them from deleting any of the other pages. Things might blow up, like, the Home shows some information collected from some of the other sections etc... but mainly because it doesn't make sense in our situation, that is: the only case in which they might delete one of the "static" pages is by accident. If they really want to delete any of these pages, that's a decision design that will involve other people (managers, designers and developers) and … -

How to Create a Profile to an user
im relative new to django, before i only created simple applications that did not require any user stuff, now however i need to create a website with users, for now i created user register, log in and log out, but im struggling to create the profile for the user, should i create an app only for profile ? or maybe put the profile together on the models inside the user app where is the user authentication is, how do i go about the views on this matter ? if someone has a simple example that even a dumb person like me can understand i would appreciate a lot, thanks in advance.

Django - get model instance from a custom field
For a new project I defined a custom field EncryptedField. In this field, I use the methods get_prep_value and from_db_value. In these methods, I have access to the value of the field, so I can encrypt and decrypt it. I also need the value of another field of the model where EncryptedField is used for the encryption/decryption. So is it possible to have access to the instance of the model that calls my custom field EncryptedField. Like that I can have access to the other field value. Or there is an other way to get the other field value in these methods? I tried to use contribute_to_class but it seems to not be adapted to get the model instance. Thanks for your help -

#a link to a thumbnail that's 200px in height - Basic #a link to a thumbnail that's 400px in height - Basic and Intermediate #a link to the originally uploaded image - Basic, Intermediate and Premium class Profile(models.Model): MEMBERSHIP = ( ('BASIC', 'Basic'), ('PREMIUM', 'Premium'), ('ENTERPRISE', 'Enterprise') ) user = models.OneToOneField(User, on_delete=models.CASCADE) membership = models.CharField(max_length=10, choices=MEMBERSHIP, default='BASIC') def __str__(self): return f'{self.user.username} {self.membership} Profile' The only way I know how to do 3 build in tiers are like above. I don't know how to do more memberships with different image sizes that can be added from admin panel. I want to have them as one model and add it as necessary to make a new user.
