django sqlite3 database not configured correctly in pycharm
I'm currently continuing a django project on windows originally written by a mac user, and I am using the PyCharm IDE. I had a lot of trouble getting the database set up for the project (using the default sqlite3). My DATABASE settings are correct, and when I check the connection the the database when running manage.py shell it says that it is connected. The only issue is that every variable that is there to access data in the database is highlighted in red, which is typically a sign of an error in the JetBrains IDEs that I've worked with. I'm still able to host the site locally what could be the cause of this issue/error? I've a couple examples of what I mean below: example 1 example 2 EDIT: I know there is a problem because if I run a model independently I get the following exception: django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. but the DJANGO_SETTINGS_MODULE was already configured correctly to the right app. Any ideas? -
Django tests are deleting production data, only work when running all tests at once
First off, this is Django 1.9.13. I realize this is an unsupported version, but I have to use it for reasons. The database is postgres 9.6. I have a project that runs about 40 tests divided amongst a few files. All test cases are TransactionTestCase that load their own fixtures through fixture = ['fixture_name.json'] I use fixtures in the app/fixtures directory that are akin to base_data.json test_a_data.json test_b_data.json ... Base data is used in most if not all test cases. But the other fixtures are used in 1 or few tests. The settings to run it are 'test': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'HOST': 0.0.0.0, 'PORT': 5432, 'NAME': <database>, 'USER': <user>, 'PASSWORD': <pass>, 'TEST': { 'NAME': 'test_database' } } When running the following command, it runs fine python manage.py app.test -v 1 --keepdb However, when running individual test cases it fails python manage.py app.test.test_A.ATestCase -v 1 --keepdb This fails with IntegrityError: Problem installing fixture '/appfixtures/test_a_data.json': Could not load <object>(pk=1): duplicate key value violates unique constraint "<uniq_constraint_name>" DETAIL: Key <key> already exists. as if the fixture is being loaded twice. I have tried inspecting the SQL Django is using and found that the object in question is only loaded once. However, the object … -
"User matching query does not exist" occurring in template but not in unit test?
In a Django project, there is a Family model defined similar to the following: class Family(BaseFamily): employee_first_name = models.CharField(max_length=255, blank=True) employee_last_name = models.CharField(max_length=255, blank=True) partner_first_name = models.CharField(max_length=255, blank=True) partner_last_name = models.CharField(max_length=255, blank=True) where BaseFamily has a package and lucy_guide foreign key: class BaseFamily(TimeStampedModel): package = models.ForeignKey('lucy_web.Package', models.SET_NULL, blank=True, null=True) lucy_guide = models.ForeignKey( User, blank=True, null=True, related_name='lucy_guide_%(class)s', limit_choices_to={'is_staff': True}) The Package model, in turn, is linked to a Company: class Package(TimeStampedModel): company = models.ForeignKey('lucy_web.Company') and a Company, in turn, has a lucy_guide and a default_package: class Company(TimeStampedModel): lucy_guide = models.ForeignKey( User, blank=True, null=True, related_name='lucy_guide_%(class)s', limit_choices_to={'is_staff': True}) default_package = models.OneToOneField( Package, blank=True, null=True, related_name='default_for_%(class)s') Now, I have a template which uses the following template tag, edit_view_family_heading: from django import template register = template.Library() @register.simple_tag def edit_view_family_heading(family): heading = [family.employee_first_name] if family.employee_last_name != family.partner_last_name: heading.append(family.employee_last_name) heading.extend([ '&', family.partner_first_name, family.partner_last_name ]) heading = [e for e in heading if e] if heading[0] == '&': heading.pop(0) if heading and heading[-1] == '&': heading.pop() if heading: if family.lucy_guide: heading.append(f'({family.lucy_guide.first_name})') return ' '.join(heading) else: return family.id However, if I try to display the template, I get the following error: Template error: In template /Users/kurtpeek/Documents/Dev/lucy2/lucy-web/dashboard/templates/dashboard.html, error at line 0 User matching query does not exist. 1 : {% … -

Django - Passing multichoice field into POST dictionary
I have a queryset generated in my forms.py file that passes into my template. The template result is a multichoice field based on the queryset. The web browser presentation is correct - it renders the queryset as a drop down choice list that I can make a selection from. Here is the template code: <tr><td>{{ form.jury_name | placeholder:'Jury Name' }}</td></tr> <tr><td><select> {% for item in form.parent_jury.field.queryset %} <option name="parent_jury" value="{{ item }}">{{ item }}</option> {% endfor %} </select></td></tr> This is all contained in a table. When the form is submitted (method = "POST") the POST dictionary has all the correct values for the keys except the parent_jury key which posts a value of ''. I've worked through several SO solutions on the views.py side, but they don't change the fact that the information available for a clean() is missing the choice field value for 'parent_jury'. How do I get the selected option from the list to attach to the 'parent_jury' key? -

Django ORM - Filter Related Objects
I apologize if this is a duplicate, but I was unable to find any other SO posts that address this matter. I have models like so: class Person(models.Model): pass class Interest(models.Model): person = models.ForeignKey(Person, related_name='interests') is_cool = models.BooleanField() I know that I can find all people who have cool interests like so: Person.objects.filter(interests__is_cool=True) However, what I really want is to get only their cool interests when I get the Person object. I know that I could always pluck the related queryset out and operate on it, like so: interests = person.interests.filter(is_cool=True) but I cannot assign it back to the person instance since the relationship is reversed. To summarize, the goal is to use the ORM directly to filter the Interest objects being returned in the person.interests queryset. -
Cross-Origin Request Blocked (Ionic + Django)

Even urls.py is clear. Everybody now how can i fixed it? Any additional code I'll add if it necessary. -

I'm creating a VueJS front-end app that uses Wagtail CMS for the backend and connects through the Wagtail APIV2. The problem I'm having is when retreiving page information via the page slug.

Django 'clearsessions' not actually doing anything
I'm using Django 1.10.7 and a database session backend. It's come to my attention that running the clearsessions command isn't doing anything for me. All of the DJANGO_SESSION rows in my database are still there, dating back as far as January. Is there some setting I have to include in the code in order for this to function properly? I thought I could simply run the clearsessions command and it would delete all sessions from my database older than 2 weeks. -
How to download file from django admin

Also I added in fieldsets file_link: readonly_fields = ('file_link',) fieldsets = ( ('Характеристики плёнки', { 'fields': (....'data', 'origin', 'file_link') }), ) So, in my django admin I have FileField which allows to upload files to directory origin_files and link to this file. But when I click on this link I'm redirecting to home page of my site. For example, I downloaded file presentation.pptx. When I get url of this file I get http://127.0.0.1:8000/admin/description/part/12/change/origin_files/Presentation.pptx How I can download this file? -

GUI CSS picker in Django
I want to add a functionality which let the user choose a "interface theme': I added a dropdown in my base.html so the user can change the theme in all the templates.

Is there an easier way to do this? -
