Running out of quotation marks. (Django statics with document.write)
This element: <img id="img" src="{% static 'pd.jpg' %}" /> should go here: popup.document.write("<img src={% static 'pd.jpg' %} />") So think i need a third kind of quotation marks, or ? popup.document.write(String(<img src="{% static 'pd.jpg' %}" />)) at least is not working. -

Django ModelForm - ManyToMany nested selection
I'm building a Django application and I'm facing an issue I don't know how to solve... I'll try to explain it as clear as I can. I've got an app called "Impostazioni" which has a model called "AnniScolastici": class AnniScolastici(models.Model): nome = models.CharField(max_length=50) class Meta: verbose_name = "Anno scolastico" verbose_name_plural = "Anni scolastici" def __str__(self): return f"{self.nome}" I also have another app called "Attivita" which has a model called "Laboratori": class Laboratori(models.Model): nome = models.CharField(max_length=25) durata = models.IntegerField(default=0) anniscolastici = models.ManyToManyField(AnniScolastici) note = models.TextField(null=True, blank=True) class Meta: verbose_name = "Laboratorio" verbose_name_plural = "Laboratori" def __str__(self): return f"{self.nome}" I've coded up another model called "RichiesteLaboratori" which is related to different models in my Django app (and on the two above, of course): class RichiesteLaboratori(models.Model): date_added = models.DateTimeField(auto_now_add=True) date_valid = models.DateTimeField(null=True, blank=True) provincia = models.ForeignKey("impostazioni.Province", related_name="richiesta_provincia", null=True, on_delete=models.CASCADE) istituto = models.ForeignKey("contatti.Istituto", related_name="richiesta_istituto", null=True, on_delete=models.CASCADE) plesso = models.ForeignKey("contatti.Plesso", related_name="richiesta_plesso", null=True, on_delete=models.CASCADE) classe = models.CharField(max_length=25) numero_studenti = models.PositiveIntegerField() nome_referente = models.CharField(max_length=50) cognome_referente = models.CharField(max_length=50) email = models.EmailField() telefono = models.CharField(max_length=20) termini_servizio = models.BooleanField() classi_attivita = models.ManyToManyField(AnniScolastici, related_name="richiesta_anniScolastici") laboratori = models.ManyToManyField(Laboratori) note = models.TextField(null=True, blank=True) approvato = models.BooleanField(default=False) class Meta: verbose_name = "Richiesta - Laboratorio" verbose_name_plural = "Richieste - Laboratorio" def __str__(self): return f"{self.pk}" I'm … -
POST method doesn't recieve any information from Form (DJANGO & BOOTSTRAP)
I have a form which registers a new user, I used Bootstrap 5 to make it look nice. However, when I press the submit button the form does not validate. The error it shows when I write print(form.errors) says that every field is required, which means it didn't recieve anything. Why does this happen? This is my code: HTML <div class="card" id='signup_card'> <div class='card-header'> <h2 class='card-title'>Sign Up</h2> </div> <div class='card-body'> <form method='POST' action="" id='create_user_form' style="color: #fff;"> {% csrf_token %} <label for='usernameInput' class="form-label">{{form.username.label}}:</label> <input type="text" id='usernameInput' style="margin-bottom: 20px;"> <label for='phoneNumberInput' class="form-label">{{form.phone_number.label}}:</label> <input type="text" id='phoneNumberInput' style="margin-bottom: 20px;"> <label for='emailInput' class="form-label">{{form.email.label}}:</label> <input type="text" id='emailInput' style="margin-bottom: 20px;"> <label for='password1Input' class="form-label">{{form.password1.label}}:</label> <input type="text" id='password1Input' style="margin-bottom: 20px;"> <label for='password2Input' class="form-label">{{form.password2.label}}:</label> <input type="text" id='password2Input' style="margin-bottom: 20px;"> <button class="btn btn-primary" type='submit'>Submit</button> </form> </div> models.py class Account(User): phone_number = BigIntegerField() forms.py class CreateAccountForm(UserCreationForm): class Meta: model = Account fields = ['username', 'email', 'phone_number', 'password1', 'password2'] views.py def signup(request): if request.method == 'GET': form = CreateAccountForm() ctx = { 'form':form } return render(request, 'signup.html', ctx) if request.method == 'POST': form = CreateAccountForm(request.POST) if form.is_valid(): form.save() else: print(form.errors) return render(request, 'index.html') -
Python Environ Django - How to specify to read a different dot env file for dev, test and prod?
Background As I am getting ready for Django deployment to production, I realized that I need to split my settings.py file into different environments. I am trying to have each environment's settings file read a different .env file for that specific environment. Like such: As seen in the documentation # website.settings.dev from .common import * import environ env = environ.Env() # Take environment variables from .env file environ.Env.read_env('.env.dev', recurse=False) print(env('SECRET_KEY')) # SECURITY WARNING: keep the secret key used in production secret! SECRET_KEY = env('SECRET_KEY') # SECURITY WARNING: don't run with debug turned on in production! DEBUG = True ... Issue The .env.dev file is never read and my SECRET_KEY env variable is never loaded onto the system, with python manage.py check, I get the following: File "C:\website\settings\dev.py", line 10, in <module> print(env('SECRET_KEY')) File "C:\project\virtual-env\lib\site-packages\environ\environ.py", line 165, in __call__ return self.get_value( File "C:\project\virtual-env\lib\site-packages\environ\environ.py", line 361, in get_value raise ImproperlyConfigured(error_msg) django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable (virtual-env) PS C:\project> However, if I were to rename my .env file back to .env and read the file with environ.Env.read_env() Everything works, and my print statement prints out my secret key. Question Why can't environ read the specified file? How to specify a file for … -
How do I reference my model in a nested folder structure to dump data in Django 3.2?
I'm using Django 3.2 and Python 3.9. I have this project directory setup + cbapp - manage.py - settings.py + models - __init__.py - crypto_currency.py In my settings.py file, I have INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'cbapp', ] I want to dump some data to a fixtures file, so I tried $ python3 manage.py dumpdata cbapp.models.crypto_currency > ./cbapp/fixtures/crypto_currency.json CommandError: No installed app with label 'cbapp.models.crypto_currency'. What's the proper way to reference my model to dump data? -
How to load editorJs scripts integrated with django after an ajax call?
I am using editorJs for my description field as follows: epic_description = EditorJsField( editorjs_config={ "tools": { "Image": { "config": { "endpoints": { "byFile": "/imageUlaod/", "byUrl": "/imageUlaod/", }, "additionalRequestHeader": [ {"content-Type": "multipart/form-data"} ], } }, "Attaches": { "config": { "endpoint": "/fileUPload/", } }, } }, blank=True, null=True, ) But I also call this form of this field via ajax to load it. And it turns out that the script for the editorJs is not loaded at all. When I looked to my console it uses the cdn url https://cdn.jsdelivr.net/sm/jsdelivr-separator.js. Now I have no idea how to solve this issue since I do not know what script to load in the first place I check at the url to see if I can download the js file. Eiih nothing. Any help would be appreciated highly. -

Upgrade Django with incompatible migrations
I'm tasked with upgrading the Django version for a project that currently uses Django 2.2.24. It contains a model (with existing migrations) that looks roughly like this: class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) type = models.ForeignKey(MembershipType, on_delete=None) Starting with Django 3.0, on_delete=None causes an error since on_delete is supposed to be a callable. In order to avoid the error, both the model and the existing migrations have to be changed. By itself, it's not an issue to change the model like this: class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) type = models.ForeignKey(MembershipType, on_delete=models.SET_NULL, null=True) But existing databases are not yet aware that the corresponding field can be nullable, so a new migration is required for that. The best way I currently see to do this is the following: change the model create&apply a migration using Django 2.2.24 change the old migrations manually Is there a more elegant way to solve this issue? -
How can I test delete view in Django app?

Use template date filters in custom template tag?
I want to use Django template date filters inside a custom template tag. Is that possible? My end goal is to be able to use it like this: {{parcel.pickup_dates|delivery_dates_formating}} Problem is, that "pickup_dates" can be array of 1 or 2 or 3 elements. My desired output is: "Sunday, 21 September" if one element, "Satardau - Sunday, 21-22 September" if 2 elements, "Friday - Sunday, 20-22 September" if 3 elements, Currenly my temlpate tag looks like this: def delivery_dates_formating(value): if len(value) == 1: return [value[0]] if len(value) == 2: return [value[0], value[1]] if len(value) == 3: return [value[0], value[2]] And in template I used to use something like: {{parcel.delivery_date|date:'E j, l'|capfirst}} I woul like to use django tempaltes date filtes, as it handels localisation. Is that possible? -
Where do Django's Field's "default" and test's "client" parameters come from?
If you search for the parameters of a Field (e.g. IntergField) in Django through from django.db import models dir(models.IntegerField) you get 'default_error_messages', 'default_validators', 'unique', 'validate', 'validators', etc, but not "default" itself, although it's commonly used, as in class Choice(models.Model): ... votes = models.IntegerField(default=0) Same thing with "client". The docs say TestCase "comes with its own client". In this snippet from Django's docs, this client is explored class QuestionIndexViewTests(TestCase): def test_no_questions(self): """ If no questions exist, an appropriate message is displayed. """ response = self.client.get(reverse('polls:index')) but you can't find it through from django.test import TestCase dir(django.test.TestCase) or even dir(django.test.TestCase.client_class) I'm asking where they come from, but also how to search for these "hidden" parameters, methods, etc. -
Django call SOAP API
I made a CRM and now the company wants to set up their API, but it's a SOAP API who uses XML and after a little research here in Stack, some people said to use zeep, and didn't work.

Django implicit field naming for class with query expression - how does it work?
Simplified example of what I wrote today: class Grandparent(models.Model): text = models.CharField(max_length=5, choices=too_many) class Parent(models.Model): grandparent = models.ForeignKey(Grandparent, on_delete=models.CASCADE) info = models.CharField(max_length=30) class ChildSomething(models.Model): parent = models.ForeignKey(Parent, on_delete=models.CASCADE) data = models.CharField(max_length=5, choices=chromosome_identities) Given a specific Grandparent object, I wanted to order Parent objects underneath it by most ChildSomething's each Parent has, which I did successfully below. grandparent = Grandparent.objects.get(id=32923) # arbitrary id # This query produces the desired result parents = ( Parent.objects.filter(grandparent=grandparent). annotate(num_child_somethings = Count('childsomething')). order_by('num_child_somethings') ) My question: Why is it Count('childsomething') instead of Count('child_something')? The latter was my intuition, which was corrected by a helpful Django error message: Exception Type: FieldError Exception Value: Cannot resolve keyword 'user_translation' into field. Choices are: id, translate_text, translate_text_id, translation, usertranslation The answer to this is likely simple, I just couldn't find anything in the docs related to this. How does the naming convention work? If anyone knows of the appropriate Django docs link that would be ideal. Thank you. -

Field data disappears in Django REST framework
I have a field "plugins" (see below) in my serializer and this is a serializer which also contains a file upload which is why the MultiPartParser is used. My view is pretty much standard, and the plugins field data also shows up in the request.data, however it doesn't show up in the validated_data of the serializer. To bring a minimalistic example, this would be my serializer: class CreationSerializer(serializers.ModelSerializer, FileUploadSerializer): plugins = serializers.ListSerializer( child=serializers.CharField(), required=False, write_only=True) class Meta: fields = ['plugins'] + FileUploadSerializer.Meta.fields model = Company def create(self, validated_data): print(validated_data) While this would be my views.py: @swagger_auto_schema(request_body=CreationSerializer(), responses={201: CreationSerializer()}, operation_id='the_post') def create(self, request, *args, **kwargs): print(request.data) return super().create(request, *args, **kwargs) # which uses mixins.CreateModelMixin -
Cleaner django filters in graphql query
