I have a simple model:
class MediaLink(models.Model):
title = models.CharField(max_length=200)
subtitle = models.TextField(max_length=2000, unique=False, blank=True)
byline = models.CharField(max_length=200, unique=False, blank=True)
url = models.URLField(unique=False)
source = models.CharField(max_length=30, unique=False)
source_url = models.CharField(max_length=30, unique=False, blank=True, null=True, choices=SURL_CHOICES)
mediatype = models.CharField(max_length=30, choices=MEDIATYPE_CHOICES)
topic = models.CharField(max_length=30, choices=TOPIC_CHOICES)
sourceinfo = models.ForeignKey(SourceInfo, blank=True, null=True)
date_added = models.DateField(auto_now_add=True)
def __unicode__(self):
return u'%s' % self.title
class Meta:
abstract = True
class Admin:
pass
I'd like to set the "subtitle" field so that in each object, its initial data is "<h3></h3>". I'm using markdown and having the tags set initially saves me from having to create them in the admin for each record.
You could just set the default on the field:
subtitle = models.TextField(max_length=2000, unique=False, blank=True, default='<h3></h3>')
Or if you're using a ModelForm you can set it in the initial kwarg.

I have model named organization. I am using this same model model for 2 api's. I have a field code. one API do code auto generation another API takes user entry code. I want to separate the tables based on code. Autogeneration code starts SUB001,SUB002,.... like wise. user entry code thats userwish.
models.py
class Organization(models.Model):
code = models.CharField(max_length=255, null=False, unique=True)
name = models.CharField(max_length=255, null=False)
organization_type = models.CharField(max_length=255, choices=TYPES, null=False, default=COMPANY)

Is there any possible to split models based on code,.. Really Expecting help...
You can use Proxymodel inheritance. Documentation
class AutoGenerationManager(models.Manager):
def get_queryset(self):
return super().get_queryset().filter(code__istartswith="SUB")
class AutoGeneration(Organization):
objects = AutoGenerationManager()
class Meta:
proxy = True
class UserGenerationManager(models.Manager):
def get_queryset(self):
return super().get_queryset().exclude(code__istartswith="SUB")
class UserGeneration(Organization):
objects = UserGenerationManager()
class Meta:
proxy = True
I have two models: 1) SchoolProfile & 2) Content
I want to show content data in schoolprofile, But data should be display as per user foreignkey.
User foreignkey common for both the models.

I have used Inline but it's show below error:
<class 'colorcast_app.admin.SchoolProfileInline'>: (admin.E202) 'colorcast_app.SchoolProfile' has no ForeignKey to 'colorcast_app.SchoolProfile'.
My admin.py
class SchoolProfileInline(InlineActionsMixin, admin.TabularInline):
model = SchoolProfile
inline_actions = []
def has_add_permission(self, request, obj=None):

class SchoolProfileAdmin(InlineActionsModelAdminMixin,
admin.ModelAdmin):
inlines = [SchoolProfileInline]
list_display = ('school_name',)
admin.site.register(SchoolProfile, SchoolProfileAdmin)
Using the StackedInline to link two models is straight forward and a much clean practice, so basically this is my solution below:
class ContentInlineAdmin(admin.StackedInline):
model = Content
#admin.register(SchoolProfile)
class SchoolProfileAdmin(admin.ModelAdmin):
list_display = ('school_name',)
inlines = [ContentInlineAdmin]

When i am creating Profile from django admin panel getting below error.

please take a look how can i fix this.
Note: User model creation working but, profile not working
I checked in drf and django admin panel .
both place not working.
The problem here is that you are declaring a User model which is in fact just a model. That's not how it works.
The User is a special type of model and if you want to change it you have to extend the AbstractUser class.
Alternatively you can connect to it via one-to-one classes in the classic user-profiles approach.
But here you are creating a user model that (besides using the reserved word 'User') has none of the requirements necessary to be treated as a user who can be authenticated and that can instantiate sessions.
> Example of a simple user-profiles architecture
> Working with User objects - Django Docs (i particularly recommend this one)
I would recommend you to read-up on django user authentication.
So I am new to Django and I have been reading a lot of documentation to figure this out, I have a table called "Logs" that has logs of different positions (has FK of table "Position"), each position belongs to a department (has FK to table "Department") Check the image below :1
What I want to do is create a view just like this one :
2
and whenever you click on a department, it extends all the positions in it with their respective logs like this :
3
The Screenshots I have attached are my work in main app (or if you would like to call it front end), I wanted to replicate the same process in the Django Admin page, I keep seeing that I should use inlines but I can't seem to make it work, can someone help or put me in the right direction please ? much appreciated.

admin.site.register(Log)
admin.site.register(Position1)
admin.site.register(Department)
admin.site.register(Site)
admin.site.register(SiteHasDepartment)
admin.site.register(SiteHasPosition)
I would like to have a page in admin.py where I can select a site and for that specific site display :
all the departments(when you press a dpt all the positions will expand) for each position the standardHC, attributes from the Log table (that match that position,and that site) and attributes from SiteHasPosition( that match the site and that position)
I hope I made it clearer
I have this table in my model, i just want that if the data is updated the modifyDate field will automatict updated.
note: i am not using the adminsite to update data
