How do I change FilePathField to FileField in a Django Model dependant on the instance of a related Model?
I am trying to create a directory based on the instance of a created participant. This directory will be used to upload files for that participant.

Django - separated settings by environment. Not finding variable from base settings
I've split my django environment as per this post. In settings/base.py I have BASE_DIR specified: BASE_DIR = Path(__file__).resolve().parent.parent.parent In settings/__init__.py I have: from .base import * env = os.environ['ENV'] ... if env == 'test': from .test import * ... In settings/test.py I have DATA_VOLUME_BASE_DIR = BASE_DIR / 'scanned_images'. I expect that Django loads the settings module, imports settings/base.py, checks the environment ('test'), imports settings/test.py (which works) and the variable is available (which isn't).

Migrations conflicts in Django, CircularDependencyError
I have a fresh new Postgres DB for my Django app. After applying the initial migrations with python3 manage.py migrate I run python3 manage.py makemigrations to create the tables for my models but no change is detected and no migrations created. This is weird but running python3 manage.py makemigrations app_name for each individual app in my project seems to work. When I try to python3 manage.py migrate I got an error: django.db.migrations.exceptions.CircularDependencyError: hub.0001_initial, crm.0001_initial where hub and crm are the names of 2 of the apps in the projects. This happens because some models in my hub app have relationships with some models in the crm app and viceversa. An effective solution would be to comment out all the relationship fields in my models, migrate, un-comment and makemigrations and migrate again to create the relationships tables. I don't want to go through all my models commenting out fields, is anyone aware of a more elegant solution? Thanks in advance. -
Django get_form results in unbound form (or what is the best way to get url parameters into a model form using CBV createview?)
I'm using a model form and a CBV (createview) to build a form. I needed to get url parameters into the form so I could access details from the previous view that sent the user to the form. To achieve this I initially tried overriding get_form as follows: def get_form(self): form = AddDataForm(key_a=self.request.GET['a'], key_b=self.request.GET['b']) return form This didn't work. The form wouldn't save (even when all fields were correctly completed). It would result in an unbound form. I eventually got a positive result by using get_form_kwargs as follows: def get_form_kwargs(self): kwargs = super().get_form_kwargs() kwargs.update({'key_a': self.request.GET['a'], 'key_b':self.request.GET['b']}) return kwargs My question is, what about get_form (or my lack of understanding of it) results in this behaviour? My forms.py is below too. class AddDataForm(forms.ModelForm): class Meta: model = MiningTech fields = '__all__' exclude = ('user',) def __init__(self, key_a, key_b, *args, **kwargs): # key_a comes from the view's get_form. super(AddDataForm, self).__init__(*args, **kwargs) if len(key_a) > 3: for field_name in self.fields: if not field_name.startswith(key_a[0:3]): # If field_name doesn't start with first 3 characters of key_a, hide it. self.fields[field_name].widget = forms.HiddenInput() print("__init__ args", kwargs) else: self.fields[field_name].required = True self.fields['slug'].initial = key_b else: print("All fields Hidden") -

DRF Image serializer with nested thumnails
I'm writing django project, in which I have the following models in my media_app application: class Image(File): """ Image model class, through which client will get images stored on AWS S3. """ # ... (not needed in serializer fields) class Thumbnail(File): """ Related model for Image, that contains thumbnails of Image. """ parent = models.ForeignKey( Image, on_delete=models.CASCADE, related_name='thumbnails', ) resolution = models.CharField( _('resolution'), max_length=11, validators=[resolution_validator], ) # ... File class is base model class for media files in my project. It contains mime_type, origina_file_name, size, etc. My question is how can I write serializer for Image, that will have the following structure: { "2775f83e-1608-4135-91d3-f357484df3b1": { "full_size": "http://localhost:8000/api/media/2775f83e-1608-4135-91d3-f357484df3b1/", "358x227": "http://localhost:8000/api/media/8809a43d-c387-4a8e-9c84-8419c406ecd8/", "190x121": "http://localhost:8000/api/media/cb32967e-a576-44ee-b636-6e3a65ec93ba/" } } Where "2775f...df3b1" is pk of Image, "full_size" its own get url (model has method/property api_url, that generate endpoint url to media file get view) and other fields ("358x227" and "190x121") are urls of related thumbnails (keys are from resolution fields in Thumbnail). This structure is not common for DRF, so I've not found the solution in documentation... Serializer will be used in other ModelSerializers.

Will it be correct if property will change the data?
@property def check_too_much_sent_confirmation(self): if self._count_of_hashes_sent >= 3: if UTC.localize(datetime.now()) <= self.updated_at + timedelta(minutes=10): return True else: self.reset_count_of_hashes_sent() return False def reset_count_of_hashes_sent(self, commit=False): self._count_of_hashes_sent = 0 self._save_if_commit(commit) In the code above, check_too_much_sent_confirmation checks if the user can send the confirmation code again, he is given 3 attempts every 10 minutes. self.reset_count_of_hashes_sent() The line above resets the number of attempts. Is it correct that a method is called from a property function that changes the data in the database? Or is it better to call this function separately? -

Is there a way to deploy Django with other web applications?
I'm starting a new personal server in a VPS (debian). I am doing the mainpage with django. I will like to add to this server/site other external apps (such as GitLab CE, Veloren , FluxRSS and Wallabag). The idea is to centralize everything through django. To have something like : Blog : webpage.com GitLab : gitlab.webpage.com Nevertheless, I cannot seem to find any tutorials or information to do this. I think there is something related to nginx and reverse proxy, but still cant find good information. I know the question is very broad but I'm out of resources and do not know where to search... I've been searching through the web (including stackoverflow) and can't seem to find what I'm looking for, so even if it is just keyword recommendations or links to possible solutions/implementations I'll be extremely happy. -
