django modeltranslation doesn't work with such queryset
I'm new to programming. In my blog I want to show a list of categories. If I create a queryset like this: Category.objects.all() my django-modeltranslation works perfectly. But I want to get categories of only published posts. Then my queryset is: Post.objects.values('category__name').filter(is_published=True) However, django-modeltranslation doesn't work. I get values from 'name' field instead 'name_en' or 'name_ru' fields. What is wrong? Here's my models.py : class Category(models.Model): name = models.TextField(max_length=100) url = models.SlugField(max_length=160, unique=True) class Post(models.Model): title = models.TextField('title', max_length=150) category = models.ManyToManyField(Category, related_name='posts', blank=True) -

Django + Google Storage (GCP) multiple bucket
For now i use django 1.11 and using google cloud platform (google storage) to store pdf. my bucket is not open for public and everything was fine, but now i need to store public file (people with link can access uploaded pdf file) I was thinking is it possible for me to have options(choose the bucket target) when upload to google storage? Maybe something like this codes from django.db import models from storages.backends.s3boto import S3BotoStorage class MyModel(models.Model): file_1 = models.FileField() # Uses default storage file_2 = models.FileField(storage=S3BotoStorage(bucket='other-bucket')) I want to do the same as this, but using GCP instead of AWS django-storages with multiple S3 Buckets I'm sorry if this question is too basic, but I've never found the answer until now Thanks for your attention, and hope you can help me and the others who faced the same problem. -

How to loop through values in JSON and assign to another dictionary
I am developing a Python/Django web app. I am trying to parse JSON into a python dictionary, read the values in the dictionary, and assign the values to another dictionary if certain conditions are met. JSON is structured like this: {content: {cars: [0, 1, 2]}, other_stuff: []} Each car has multiple attributes: 0: {"make", "model", "power"...} Each attribute has three variables: make: {"value": "Toyota", "unit": "", "user_edited": "false"} I am trying to assign the values in the JSON to other dictionaries; car_0, car_1 and car_2. In this case the JSON response is otherwise identical considering each car, but the 'make' of the first car is changed to 'Nissan', and I'm trying to then change the make of the car_0 also to 'Nissan'. I'm parsing JSON in the following way: local_cars = [car_0, car_1, car_2] # Dictionaries which are already initialized. print(local_cars[0]['make']['value']) # Prints: Toyota (yes) print(local_cars[1]['make']['value']) # Prints: Toyota (yes) print(local_cars[2]['make']['value']) # Prints: Toyota (yes) counter = 0 if request.method == 'POST': payload = json.loads(request.body) if bool(payload): print(len(local_cars)) # Prints: 3 print(counter, payload['cars'][0]['make']['value']) # Prints: Nissan (yes) print(counter, payload['cars'][1]['make']['value']) # Prints: Toyota (yes) print(counter, payload['cars'][2]['make']['value']) # Prints: Toyota (yes) print(counter, local_cars[0]['make']['value']) # Prints: Toyota (yes) print(counter, local_cars[1]['make']['value']) # Prints: Toyota … -

Why Django modelform is submitted with enter key
I'm using Django modelform and it's submitted by pressing the enter key. This is what I wanted, but I don't know why it works. I didn't add any JS codes related to keydown but other codes to practice Ajax. Also, I found out that when there's only one input inside the form, it's submitted with the enter key, but my form has two inputs. What I'm doing is to add a comment on a post like instagram. I used Ajax to create a comment instance. models.py class Comment(models.Model): parent_post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="comments") author = models.CharField(max_length=10) content = models.CharField(max_length=100) forms.py class CommentForm(ModelForm): class Meta: model = Comment exclude = ["parent_post"] HTML {% for post in posts %} <form method="POST" data-id="{{post.id}}" class="d-flex align-items-center w-100 mt-2"> {% load widget_tweaks %} <!-- this is a django package for easy CSS --> {% csrf_token %} {{ form.non_field_errors }} <div class="fieldWrapper"> {{ form.author.errors }} {{ form.author|add_class:"form__author"|attr:"placeholder:name" }} </div> <div class="fieldWrapper w-100"> {{ form.content.errors }} {{ form.content|add_class:"form__content"|attr:"placeholder:content" }} </div> <button class="btn btn-sm btn-warning w-auto">Write</button> </form> {% endfor %} JS (Here I didn't put the codes after getting JSON response from views.py) const forms = document.querySelectorAll("form"); forms.forEach((value) => { const post_id = Number(value.getAttribute("data-id")); value.addEventListener("submit", (e) => { … -
Django memory leak after network disconnected?

Migrating Django TextChoices to IntegerChoices
In Django (3.2.8), I have a set of TextChoices, which I would like to change to IntegerChoices. I will keep the keys the same, just the values in the database stored will just differ. I do this for consistency and I'm fixing some legacy code. Naturally, I changed the TextChoices to IntegerChoices, and the corresponding field to an IntegerField. As expected however, upon migrating, I get a django.db.utils.DataError: invalid input syntax for type integer: "option1". I feel like there should be a way that I can define a mapping for this migration to happen, but wasn't able to find any documentation on this. -

Default storage delete method not working under windows [WinError 123]
I have the following issue. I wrote a unit test which works great under UNIX but breaks for Win10. I am uploading a file using Djangos default_storage: from django.core.files.storage import default_storage uploaded_file = SimpleUploadedFile(self.testfile_name, file.read(), content_type='multipart/form-data') response = self.client.post(url, {'file': uploaded_file}, *args, **kwargs)) testfile_new_path = response.data.get('file') ... default_storage.delete(testfile_new_path) When I want to remove the file after my test, I get an [WinError 123] error stating that the file doesn't exist. Actually this is true because testfile_new_path looks like this: C:\workspace\project\media\http:\testserver\media\path\to\my_file.txt Obviously, something is broken. I wonder how to do this properly. After all, I am using default Django methods. Thx! -
How do you fix favicon and manifest image issue while building Python Django Website?
I am fairly new to coding and I'm doing this course where they teach you to build your own portfolio website suing python django. So far, everything has been going great.

How can I automatically create an approve/reject history when I approve a request or return item?

Make fields in updateAccount mutation optional django graphql auth
