Greetings all,
I'm working on a project, and I didn't like the default solid grey lines in
each form-row, so I extended the change_form.html to remove them. However,
in doing so, the autocomplete select2 field broke (raw_id_fields breaks as
well). I've been looking for a workaround on this issue, and I don't know
if it's a bug or not. If anyone has a workaround, I would appreciate
hearing what it is (though I would prefer not to modify any files in the
Django package). And, if anyone wants to replicate the issue, I've included
a test case below, but please let me know if I forgot anything.
Any thoughts or help is greatly appreciated.
Regards,
Jason
*Autocomplete_fields with **extended** change_form.html test*
1. Install Python (I have version 3.7.2 64 bit installed on Windows 10 Pro).
2. Run the following commands in your working directory:
a. mkdir djangotest.
b. cd bugtest
c. python -m venv venv
d. .\venv\scripts\activate
e. django-admin startproject bugtest .
f. python manage.py startapp testing
g. python manage.py migrate
3. Update installed apps settings in .\djangotest\bugtest\settings.py
INSTALLED_APPS = [
'testing.apps.TestingConfig',
# leave default apps...
]
4. Change .\djangotest\testing\models.py to the following:
from django.db import models
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question_text
class Choice(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str__(self):
return self.choice_text
5. Change .\djangotest\testing\admin.py to the following:
from .models import Question, Choice
class QuestionAdmin(admin.ModelAdmin):
ordering = ['pub_date']
search_fields = ['question_text']
class ChoiceAdmin(admin.ModelAdmin):
autocomplete_fields = ['question']
#raw_id_fields = ('question',)
admin.site.register(Question, QuestionAdmin)
admin.site.register(Choice, ChoiceAdmin)
6. Run the following commands:
a. python manage.py migrate
b. python manage.py makemigrations testing
c. python manage.py migrate testing
d. python manage.py createsuperuser (enter in info for testing superuser).
e. python manage.py runserver
7. Open http://127.0.0.1:8000/admin/testing/choice/add/ in browser (I'm
using Chrome version 73.0.3683.103 (Official Build) (64-bit)).
8. Verify that the foreign key field (question) is working as expected.
9. Create the following directories: .\djangotest\testing\templates,
.\djangotest\testing\templates\admin
10. Create change_form.html file in .\djangotest\testing\templates\admin
with the following information:
{% extends "admin/change_form.html" %}
{% block extrahead %}
<style>
.form-row {
border-bottom: none;
}
</style>
{% endblock %}
11. Reload http://127.0.0.1:8000/admin/testing/choice/add/ in browser.
12. Verify that foreign key field (question) is not working as expected.
