Difference between tests and interactive shell: files deleted only in the shell
Django 1.11.7 django_cleanup 1.0.1 Django-cleanup deleteы old files on model instance deletion etc. Model: class FileModel(models.Model): file = models.FileField() Currently in MEDIA_ROOT there is a file cache.txt. Just a file. We'll use it in tests. Let's create an instance in the shell: from django.core.files import File file = File(open('/home/michael/PycharmProjects/experiment/media/cache.txt', 'r')) fm = FileModel.objects.create(file=file) In MEDIA_ROOT cache_JO2jFJC.txt appears. Delete it in the shell: fm.delete() (1, {'files.FileModel': 1}) In MEDIA_ROOT cache_JO2jFJC.txt has been deleted. Now there is only cache.txt in MEDIA_ROOT directory. Thefore, django-cleanup works correctly. Let's do the same in a test. And there is a breakpoint put there (have a look at the comment below). class FileTest(TestCase): def test_create_delete(self): file = File(open('/home/michael/PycharmProjects/experiment/media/cache.txt', 'r')) fm = FileModel.objects.create(file=file) fm.delete() # Breakpoint pass At the breakpoint we stop and look around. Aha, the file cache_D9IuGrI.txt appeared in MEDIA_ROOT. Resume. Well, the file is here. It is not deleted. Here is a link to the app: https://github.com/un1t/django-cleanup Direct link to handlers: https://github.com/un1t/django-clean...up/handlers.py Well, handlers listen to signals. Seems logical. How can it be that files are deleted in interactive shell but not in tests? -

I have a Product model, an Image Model and a Category Model. A Product can have multiple Images(Foreign Key) and a Product can be in multiple Categories a Category can contain multiple Products. A Category can have multiple subcategories(key to itself). class Category(MetaData): parent = models.ForeignKey('self', blank=True, null=True, verbose_name='parent category', on_delete=models.CASCADE) class ProductMetaData): categories = models.ManyToManyField(Category) class ProductImage(models.Model): product = models.ForeignKey(Product, related_name='image', on_delete=models.CASCADE) In Product Django Admin: class ProductDocumentInline(admin.TabularInline): model = ProductDocument class ProductAdmin(MetaData): inlines = [ProductImageInline] fieldsets = ( ('Product Data', { 'fields': ('name', 'short_description', 'description') }), ('SEO', { 'classes': ('collapse',), 'fields': ('meta_title', 'meta_description', 'slug', 'canonical') }), ('MetaData', { 'classes': ('collapse',), 'fields': (('created_at', 'created_by'), ('updated_at', 'updated_by')) }), ) readonly_fields = ('created_at', 'updated_at', 'created_by', 'updated_by') list_display = ('name', 'updated_at') ordering = ('-updated_at',) search_fields = ('name',) admin.site.register(Product, ProductAdmin) admin.site.register(ProductImage) Issues: If I don't customize fieldsets (grouped, ordered) the Categories appear like default in the middle of the form. If there are customized as in my example they don't appear. If they don't appear Products without Categories can be created and I don't want that. I want a product to have at least one category. Now the inline Images appear below all Product fields. I want the Categories to appear first, then … -

A for loop in forms.py fails to load data immediately after it's sent | Python Django
In the forms.py I have a short piece of code which loads the data, but only after I edit print("hello") in it. The code as follows: models.py: class CreateAssignment(models.Model): user = models.ForeignKey(User, editable=False, blank=True, null=True) progress = models.CharField(max_length=254, editable=False, blank=True, null=True) class SetAssignment(models.Model): mechanic = models.ForeignKey(User, editable=False, blank=True, null=True) assignment = models.IntegerField(blank=True, null=True) The mechanic is a permission, plus this mechanic's ID will show in the url of the website, when you will try to set an assignment for this mechanic. forms.py: class SetAssignmentForm(forms.ModelForm): ASSIGNMENT_CHOICES = () for item in CreateAssignment.objects.all(): if item.progress == 'Scheduling': user = User.objects.get(id=item.user_id).username ASSIGNMENT_CHOICES += ( (item.id, user + ' - ' + str(item.id)), ) assignment = forms.ChoiceField(choices=ASSIGNMENT_CHOICES, help_text='This is the assignment that you want to apply to this mechanic.') class Meta: model = SetAssignment fields = ('assignment', ) The user_id in this situation is the user that has been set in the CreateAssignment model. Now the issue is: - The for loop in the SetAssignmentForm works, but it loads data after I put a print in it or when I remove the print from it. Which of course shouldn't really affect the code. Is there something I'm overlooking? I've been programming in Python Django … -

How to write automatic test when django-cleanup is used
Django 1.11.6 I use django-cleanup==1.0.1. That is: https://github.com/un1t/django-cleanup/tree/master/django_cleanup/testapp It works: I have tried by hand. My model: class ItemFile(ChecksumMixin, models.Model): file = models.FileField(blank=False, max_length=255, upload_to=get_item_path, verbose_name=_("file")) This django-cleanup automatically deletes old files for FileField. If I delete ItemFile instances by hand through Django admin, files on the disk are really deleted. I try to write tests for how this functionality is working in my project: class ItemTests(TestCase): def test_delete_files_on_models_instance_deletion(self): itemfile = ItemFile.objects.create(file=source_file) itemfile.delete() destination_dir = os.path.join(settings.MEDIA_ROOT,...) file_list = os.listdir(destination_dir) self.assertEqual(len(file_list), 0) The problem: this test does not delete the file. This is the direct link to django-cleanup handlers: https://github.com/un1t/django-cleanup/blob/master/django_cleanup/handlers.py It uses signals: post_delete etc. Could you tell me whether this signal will intercept the fork flow in case of my test? Maybe the point is that signals are just ignored in this case. If I am right, how could I test this functionality? -

Django-registration redirect after login ( {{next}} )
I'm using django-registration to user login in on my website. I need to redirect user to my custom page. As far as I understand all views and forms are built in, so I can't custom them.I need to change "next" variable to redirect me to another page. I've tried: <input type="hidden" name="next" value="{% url 'orders' %}"> This code redirects me to this page, using url's name, but django recognized user as not authenticated(not logged in) Any examples, and advices will be usefull. Thx. -
How `TemplateView` populate context with kwargs?
Django documentation specifies 'TemplateView' in BaseView It says: TemplateView Renders a given template, with the context containing parameters captured in the URL. and Context is pulated (through ContextMixin) with the keyword arguments captured from the URL pattern that served the view. "TemplateView" captures request in URL,this is what I can interpret. Nevertheless,parameters are usually grabbed from database to bond context? How can 'TemplateView' fetch them form a captured URL? -
How to test content of a Django email?
I'm new to Django and am trying to use unittest to check if there's some text in an outbound email: class test_send_daily_email(TestCase): def test_success(self): self.assertIn(mail.outbox[0].body, "\nMy email's contents\n") However, I'm having an issue with mail.outbox[0].body. It will output My email&#39s contents and won't match the test text. I've attempted a few different fixes with no luck: str(mail.outbox[0].body).rstrip() - returns an idential string str(mail.outbox[0].body).decode('utf-8') - no attribute decode Apologies, I know this must be a trivial task. In Rails I would use something like Nokogiri to parse the text. What's the right way to parse this in Django? I wasn't able to find instructions on this in the documentation. -
