Question

Ok, so here’s the skinny:

# models.py class Article( models.Model ):     title           = models.CharField( max_length = 255 )     author          = models.ForeignKey( User )     published_at    = models.DateTimeField( auto_now_add = True )     body            = models.TextField( )      def __unicode__( self ):         return self.title  # admin.py from hpccoe.news.models import Article from django.contrib import admin from django import forms from django.forms import widgets  class ArticleAdminForm( forms.ModelForm ):         title   = forms.CharField( max_length = 255, required = True )     body    = forms.CharField( required = True, widget = widgets.Textarea )  class ArticleAdmin( admin.ModelAdmin ):     fields  = [ 'title', 'body' ]     form    = ArticleAdminForm  admin.site.register( Article, ArticleAdmin ) 

As you can see, I’m omitting the author field in the Admin form. I want to, somehow, auto-fill this before it’s saved. How do I make that happen? I’ve been on Google for the last hour to no avail.

Thanks in advance.

From the Django Docs:

ModelAdmin.save_model(self, request, obj, form, change) 

The save_model method is given the HttpRequest, a model instance, a ModelForm instance and a boolean value based on whether it is adding or changing the object. Here you can do any pre- or post-save operations.

For example to attach request.user to the object prior to saving:

from django.contrib import admin  class ArticleAdmin(admin.ModelAdmin):     def save_model(self, request, obj, form, change):         obj.user = request.user         super().save_model(request, obj, form, change)
