Django - uploading data to a model with pandas ".to_sql()" causes problems for the foreign key field
I identified a problem that ".select_related()" doesn't work if the table with a foreign key was uploaded using pandas. Uploading data the alternative way using a loop is not an option because the table is too big. Here's an example: Set up #Models class Magazine(models.Model): name = models.CharField(max_length=20, unique=True, primary_key=True) founded = models.CharField(max_length=20, unique=True, primary_key=True) def __str__(self): return self.name class Issue(models.Model): name = models.ForeignKey(Magazine, on_delete=models.CASCADE, db_column="name") week = models.CharField(max_length=10, unique=False) def __str__(self): return self.week #Admin from mainsite.models import Magazine, Issue admin.site.register(Magazine) admin.site.register(Issue) #Migrated python ../manage.py makemigrations python ../manage.py migrate Fill first table import os import sys import pandas as pd import django sys.path.append(os.path.dirname(os.getcwd())) os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings') #configures the settings for the project. Need to do this before manipulating models django.setup() from mainsite.models import Magazine, Issue magazineNames = ['journal science', 'naughty mag', 'funny cartoons', 'comic fans', 'lawncare', 'NEVERISSUED'] magazineFounded = ['1901', '1995', '2005', '2011', '1993', '1900'] Magazine.objects.bulk_create([Magazine(name=i, founded=j) for i,j in zip(magazineNames, magazineFounded)]) Fill second table 1.) THIS WORKS for Issue.objects.select_related("name"), but uses a loop. It works because I can specify the names being a Magazine() instance. issueNames = ['journal science', 'journal science', 'naughty mag', 'funny cartoons', 'comic fans', 'lawncare', 'lawncare'] issueWeeks = ['1', '2', '3', '4', '5', '6', '7'] Issue.objects.bulk_create([Issue(name=Magazine(name=i), week=j) … -

Serving Django static admin files with debug off in Elastic Beanstalk
Per other posts on this subject, I followed the advice at https://bestprogrammingblogs.blogspot.com/2021/03/django-static-files-not-working-when-debug-is-false.html to serve static files when debug is false. The site advises to make changes to Settings and URLs respectively STATIC_URL = '/static/' MEDIA_URL = '/media/' if DEBUG: STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] else: STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_ROOT = os.path.join(BASE_DIR, 'media') and in URLs re_path(r'^media/(?P<path>.*)$', serve,{'document_root': settings.MEDIA_ROOT}), re_path(r'^static/(?P<path>.*)$', serve,{'document_root': settings.STATIC_ROOT}), path('admin/', admin.site.urls), For some reason, my local admin works but the AWS admin site does not. Do I need to tune anything on the AWS side to get this working? My environment variables don't explicitly have any static settings at the moment. -

Django radio button values in views

How to modify a Django Model field on `.save()` whose value depends on the incoming changes?
I have fields in multiple related models whose values are fully derived from other fields both in the model being saved and from fields in related models. I wanted to automate their value maintenance so that they are always current/valid, so I wrote a base class that each model inherits from. It overrides the .save() and .delete(). It pretty much works except for when multiple updates are triggered via changes to a through model of a M:M relationship. So for example, I have a test that creates 2 through model records, which triggers updates to a model named Infusate: glu_t = Tracer.objects.create(compound=glu) c16_t = Tracer.objects.create(compound=c16) io = Infusate.objects.create(short_name="ti") InfusateTracer.objects.create(infusate=io, tracer=glu_t, concentration=1.0) InfusateTracer.objects.create(infusate=io, tracer=c16_t, concentration=2.0) print(f"Name: {infusate.name}") Infusate.objects.get(name="ti{C16:0-[5,6-13C5,17O1];glucose-[2,3-13C5,4-17O1]}") The save() override looks like this: def save(self, *args, **kwargs): # Set the changed value triggering this update so that the derived value of the automatically updated field reflects the new values: super().save(*args, **kwargs) # Update the fields that change due to the above change (if any) self.update_decorated_fields() # Note, I cannot call save again because I get a duplicate exception: # super().save(*args, **kwargs) # Percolate changes up to the parents (if any) self.call_parent_updaters() The automatically maintained field updates are performed here.

How do I iterate every item in a Django field using the <input type="select">?

Here is my code for Form: class AddForum(forms.ModelForm): class Meta: model = Forum fields = '__all__' labels = { 'post_title': 'Title of your post:', 'post_body': 'Content of your post:', 'author': 'Author:', 'forum_image': 'Attach image:', } def __init__(self, *args, **kwargs): super(AddForum, self).__init__(*args, **kwargs) self.fields['forum_image'].required = False I learned how to use <input> to add the post_title: <input class="for_post_title" type="text" name="post_title" placeholder="Forum Title"> like so. However, the author field as shown in Form must be entered using the dropdown menu. How should I iterate every existing author in the Django database and have it shown using the <select> element? -

Django. Star rating multiple form displayed in a grid view not working

The problem is that only the first item in the grid can be rated. I tried to assign each form an unique id but that didn't work.
