How to filter objects by many to many attribute
Please help me to solve the following problem: I have two models, for example: class Student(model.Model): first_name = models.Charfield() last_name = models.Charfield() class Teacher(model.Model): first_name = models.Charfield() last_name = models.Charfield() subject = models.Charfield() students = models.ManyToManyField('Student') A teacher object can have many students. When adding a new teacher, his students are immediately indicated, but a check must be performed for each student that this student is not tied to another teacher with the same subject. Please help me how to organize this check (I suppose using a filter). Thanks a lot in advance! I tried to use filter like Teacher.objects.filter(subject=self.subject), but don't know how to check every student here -

403 error while fetching from my own server: CSRF Token missing
I have a social-media-like page that displays all posts by each user and users are able to edit their own posts with an Edit button. When the edit button is clicked, a textarea pre-filled with post content plus a Save and a Cancel button are displayed. When the Save button is clicked, I make a fetch request to update the content without reloading the page. However, I'm getting 403 because the csrf token is missing. What confuse me is that I don't have a form in my HTML template. Where should I put {% csrf_token %}? network.js: function clearEditView(postId) { // Show edit button and original content document.getElementById(`edit_button_${postId}`).style.display = "block"; document.getElementById(`content_${postId}`).style.display = "block"; // Hide edit form document.getElementById(`edit_form_${postId}`).style.display = "none"; } document.addEventListener('DOMContentLoaded', function() { // Add event listener that listens for any clicks on the page document.addEventListener('click', event => { // Save the element the user clicked on const element = event.target; // If the thing the user clicked is the edit button if (element.id.startsWith('edit_button_')) { // Save necessary variables const editButton = element; const postId = editButton.dataset.id; const saveButton = document.getElementById(`save_${postId}`); const cancelButton = document.getElementById(`cancel_${postId}`); const postText = document.getElementById(`content_${postId}`); // Hide edit button and original content editButton.style.display = "none"; … -
Django include template as variable to use in default

How to set allow_null=True for all ModelSerializer fields in Django REST framework
I have a ModelSerializer . I want to set allow_null=True for all of the fields of the serializer . But I don't want to do it manually, I mean- I don't want to write allow_null=True for every field . Is there any shortcut? Is there anything like read_only_fields=() ? This is my Serializer class ProductPublicListSerializer(serializers.ModelSerializer): minimum_price = serializers.FloatField(source='min_product_price', allow_null=True) maximum_price = serializers.FloatField(source='max_product_price', allow_null=True) # rating = serializers.FloatField(source='productreview__rating', read_only=True) class Meta: model = Product fields = ( 'id', 'name', 'featured_image', 'minimum_price', 'maximum_price', 'total_review', 'average_rating') read_only_fields = ('name', 'featured_image', 'minimum_price', 'total_review') -
How to optimize a query on a model with foreign keys AND many to many field

Hardcode the value of a child class model field to be = to a field value in its parent
In a Django model, I would like to force a field of a child class to have a fixed value inherited from of a field of its parent. E.g.: from django.db import models class Entity(models.Model): class Type(models.TextChoices): Natural = ("Natural", "natural") Juridical = ("Juridical", "juridical") entity_type = models.CharField( max_length=9, choices=Type.choices, default=Type.Natural, ) class Person(Entity): person_type = Entity.Type.Natural # <--- forcing it to be 'Natural' from parent class ... I want to create such person_type field and forcing its value to be 'Natural' for each person object created using the Person class. This field can then be displayed in the admin, but the user must not have any kind of option to modify it. Same in the DB, ideally. I found nothing which relates to this idea in the doc: https://docs.djangoproject.com/en/4.1/ref/models/fields/ and I'm not able to apply this answer to set the value of the person_type field: https://stackoverflow.com/a/68113461/6630397 -

pipenv pytest ignores source changes or uses cached source?
I have a Django 4.0.6 project, Python 3.9.15, Ubuntu 22.10, pipenv 2022.10.25, pytest 7.1.2 The test output was cached somewhere and now any modification is ignored unless I delete the method. The steps I performed: Run the test: pipenv run pytest src/some/path/models.py The test fails, showing the correct error in traceback. Modify the method body. Run the test again. The test fails again, BUT the traceback shows old code, unmodified. Removing the method solves the problem, but any modification made to the method source makes it appear again in traceback, UNMODIFIED. Does pipenv/pytest/whatever cache the source somewhere? pipenv run pytest src/some/path/models.py --cache-clear did not help. As well as removing the .pytest_cache/. I tried removing the venv/some/path/__pycache__/models.cpython-39.pyc file (and all compiled *.pyc files in venv) But nothing seem to help. The same traceback appears every time I run tests. -
