admin.py
Consider if models.py file is as follows
from django.db import models
from django.contrib.auth.models import User
class Org(models.Model):
name = models.CharField(max_length=200)
address = models.TextField()
orgId = models.CharField(max_length=50, unique=True)
# add specific plural name to be shown in admin panel for the model
class Meta:
verbose_name = 'Organization'
verbose_name_plural = 'Organizations'
class Tag(models.Model):
name = models.CharField(max_length=50)
class Opportunity(models.Model):
status = models.CharField(max_length=50)
description = models.TextField(null=True, blank=True)
display_name = models.CharField(max_length=100)
order_by = models.IntegerField(default=0)
is_active = models.BooleanField(default=False)
created = models.DateTimeField(auto_now_add=True)
modified = models.DateTimeField(auto_now=True)
organization = models.ForeignKey('Org')
tags = models.ManyToManyField('Tag')
Then admin.py file would be something like this
from django.contrib import admin
from .models import Opportunity
class adminOpportunity(admin.ModelAdmin):
list_display = ('get_orgId', 'display_name', 'status', 'order_by', 'is_active')
list_display_links = ('get_orgId', 'display_name')
list_editable = ['order_by', 'display_name', 'status']
list_filter = ('is_active','created','modified')
filter_horizontal = ('tags',) # available for many to meny fields only
raw_id_fields = ("organization",)
search_fields = ('org__orgId', 'status')
# Choose fields that are displayed in admin form, all other fields that
# not included in the list given below should probably have null=True, blank=True
fields = ('display_name', 'status', 'organization')
# or show every field in form except the specified below
exclude = ('order_by',)
# To display multiple fields on the same line, wrap those fields in their own tuple.
# In this example, the url and title fields will display on the same line and the
# content field will be displayed below them on its own line
fields = (('url', 'title'), 'content')
# to divide adimin form in sections with specific section headers
fieldsets = [
(None, {'fields': ['display_name', 'status']}),
('Related Organization', {'fields': ['organization'], 'classes': ['collapse']}),
]
def get_orgId(self, obj):
return obj.org.orgId
get_orgId.short_description = 'Organization ID'
get_orgId.admin_order_field = 'org__orgId'
get_orgId.empty_value_display = '???'
class Meta:
model = Opportunity
admin.site.register(Opportunity, adminOpportunity)
# add custome name to admin panel
admin.site.site_header = 'My Admin Panel'
