Saving Nested Django Serializer
I have 3 models. Question, Choice, and Cover. Question can have many choices and each choice can have only 1 cover. I implemented the Question and Choice as serializers and it worked successfully, now i'm trying to add on the Cover. Here's what I have: class CreateQuestionSerializer(serializers.ModelSerializer): choice_set = ChoiceSerializer(many=True) class Meta: model = Question fields = ('user', 'status', 'choice_set') def create(self, validated_data): choices_validated_data = validated_data.pop('choice_set') question = Question.objects.create(**validated_data) choices_serializer = self.fields['choice_set'] for choice in choices_validated_data: choice['question'] = question choices_serializer.create(choices_validated_data) return question class ChoiceSerializer(serializers.ModelSerializer): choice_cover = ChoiceCoverSerializer(many=False) class Meta: model = Choice fields = ('choice', 'choice_cover') class ChoiceCoverSerializer(serializers.ModelSerializer): class Meta: model = ChoiceCover fields = ('cover',) When I try to save data like so: { "user": 179, "question": "Who will win the election?", "choice_set": [ { "choice": "Lorem", "choice_cover": "C4FF33" }, { "choice": "Ipsum", "choice_cover": "FF5733" } ] } I get the following error: { "choice_set": [ { "choice_cover": { "non_field_errors": [ "Invalid data.

I'm using the Bootstrap admin library in order to use Bootstrap templates in admin. Now I want to override the Bootstrap admin templates.

Django - logout view customisation fail
I'm fairly new to Django and in order to pass in more context to logout view I tried 2 methods to customise the logout view: Method 1: from django.contrib.auth import views as auth_views from boutique.models import Category app_name = 'users' urlpatterns = [ ... path('logout/', auth_views.LogoutView.as_view(), {'categories': Category.objects.all()}), # I also tried this: # path('logout/', auth_views.LogoutView.as_view({'categories': Category.objects.all()}), # I also tried this: # path('logout-customised-url/, auth_views.LogoutView.as_view(), {'categories': Category.objects.all()}), # This is working tho it wouldn't be automatically redirect to this path when logged out Method 2: ... path('logout/', views.NewLogoutView.as_view()), # NewLogoutView code below: views.py from boutique.models import Category from django.contrib.auth.views import LogoutView class NewLogoutView(LogoutView): def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['categories'] = Category.objects.all() return context Still not working, I guess the two methods are trying to do exactly the same thing... Is there any workaround? Thanks! -
Rest Framework deserialize one field and serilize model object
Hi I want to deserialize only using 1 field. However, I want to serialize it as an object depending on the model. Suppose I have: #models.py class Product(models.Model): name = models.CharField() amount = models.IntegerField() description = models.TextField() class Query(models.Model): name = models.CharField() product = models.ForeignKey(Product) ... #serializers.py class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = '__all__' class QuerySerializer(serializers.ModelSerializer): product = ProductSerializer() class Meta: model = Query fields = '__all__' I want to POST/deserialize something like this on the QuerySerializer: { "name": "Query 1", "product": "Banana", ... } and I want something like this in return for serializer: { "name": "Query 1", "product": { "name": "Banana", "amount": 1, "description": "Banana description" } ... } I know a way is overriding to_internal_value but I do not like it since it messes up with ValidationErrrors. -

Django - Handle Multiple different Level Nest Model
I have some question about django nested model. As i know, to handle nested data structure, i must de-serialize every data, then create the object that will connected with ForeignKeyField. I could handle this by override the .create() method by separate every nested data by .pop() and create each object model separately. Here is the example how i handle 2 level nested data (based on documentation: DRF Documentation) def create(self, validated_data): child_data = validated_data.pop('child_data') parent_obj = ParentModel.objects.create(**validated_data) for data in child_data: ChildModel.objects.create(parent_id=parent_obj, **data) return parent_obj I have some trouble here. I have multiple multi level data structure, maybe like data below: "data_a": [ { "data_a_1": [ { "data_a_1_1": [ { "data_a_1_1_1": "example_a_1_1_1", "data_a_1_1_2": "example_a_1_1_2" } ] }, { "data_a_1_2_1": "Example a-1-2-1", "data_a_1_2_2": "Example a-1-2-2" } ] "data_a_2": [ { "data_a_2_1": "Example a-2-1" }, { "data_a_2_2": "Example a-2-2" } ] } ] My question is: What is the best way to handle dynamic data structure like this? It will take a long hardcoded script to handle multiple multilevel data structure by override .create() as i mention above. Any other best practice to handle mentioned data-strucure? -
Wagtail-ModelTranslation Template Fragment Caching
I've implemented a multilingual site using wagtail and wagtail-modeltranslation but I'm having a problem with template fragment caching. The cache works but is not respecting the separate languages. Whichever language is accessed first after a save, is the one that will be served for all languages. I've tried two ways of setting the cache key to no avail. First from the django docs, second trying to explicitly include the language code in the template First: {% cache 604800 about_copy LANGUAGE_CODE %} ... HTML ... {% endcache %} Second: Using a simple template tag from django.utils.translation import get_language @register.simple_tag(takes_context=True) def get_lang(context, *args, **kwargs): return get_language() {% cache 604800 about_copy get_lang %} ... HTML ... {% endcache %} My save method is as follows: def save(self, *args, **kwargs): """Create a template fragment key. Then delete the key.""" key = make_template_fragment_key("about_copy") cache.delete(key) return super().save(*args, **kwargs) This does clear the correct fragment regardless of not including any language related arguments Any help would be greatly appreciated. Thanks! -

Python rq.worker not honoring Django's LOGGING config
I am trying to run a standalone script outside of a Django app that interfaces with a Redis queue and uses the Python rq module. Everything is working fine but somewhere in either upgrading to Python 3.8 (from 2.7) or upgrading from Django 2.2 (from 1.11) or from rq to 1.2.2 (from 0.13) rq stopped honoring the Django LOGGING config.

Is it a security risk to place protected media beside public media in Django app?
First of all, this is not a duplicate, as all other related questions are outdated and do not answer this specific question. In my Django 2.2 app I need to store public media files, as well as private media files. I have researched all possible options, and have concluded that an easy option might be using the following media urls: (Base url, ‘/media/) Public: ‘media/public’ Private ‘media/private’ With the following Nginx location config: location: media/public Internal Alias: media/public Location: media/private Internal Alias: media/private With the following view config: Def publicView(request): // view config // [“x-send-redirect”] // etc.. @login_required() Def PrivateView(request): // view config // [“x-send-file”] //etc.. Is the above secure? Is having both public and private inside media a security issue? Is it frowned upon to place a path like ‘media/private’ in a location block in nginx? (Please ignore syntax errors, I am posting this from cellphone) Thank you. -
Bulk insert in Django Rest Framework JSONAPI
I'm implementing a DRFJSonAPI API: https://django-rest-framework-json-api.readthedocs.io/en/stable/index.html However, I got stuck on trying to implement a bulk insert, it seems that the JSONAPI specification doesn't mention anything about it I found only this referring to it as an experimental feature: https://springbot.github.io/json-api/extensions/bulk/ and it doesn't seem to be implemented by DRF JSONAPI I've tried several approaches, from the basic of having a new @action defined on my viewset, to even just adding the DRF api_view and going from there. But what it looks like is that my serializer doesn't understand correctly the data and returns an empty dictionary.

Django Datepicker and Autocomplete not rendering when used together
i am using Django, bootstrap_datepicker_plus and django-autocomplete-light. I had no issues when i used the 2 libraries separately, but when i attempt to use them both in the same form, for some reason, only the autocomplete widget is working, while the datepicker widget is not.

Api Post always has user as null even though there is a logged in user
I am trying to have an api for my answers app. When a post is created, the user is always set to null. I am not sure of why that is.

Many-to-many relationship between Django User, Permissions, and another entity
Consider a Django web app for CompanyXYZ that provides goods and services to many organizations. Users of the app will be affiliated with one or more of those organizations, and have different roles (and be permitted access to different data) within each. So, imagine a schema like this: Users>---UserOrg---- Permissions relate to services provided by the company, and in general look like: “Can order X”, “Can view X orders”, “Can order Y”, “Can view Y orders”, “Can order Z”...etc. Users should be able to log on to CompanyXYZ’s site once, and then choose from among his/her affiliated organizations to view summary data and/or place orders, depending on his/her permissions at a given organization. From an admin perspective, I need to be able to create organizations, create users, assign users to organizations, and assign permissions to users for each organization. I’m fairly new to Django, so I'm not sure if this is even doable. How would I start?
