displaying album title for appropriate image (ForiegnKey)
I am trying to display the album titles related to my image in my admin
interface
class Album(models.Model):
title = models.CharField(max_length = 60)
def __unicode__(self):
return self.title
class Tag(models.Model):
tag = models.CharField(max_length = 50)
def __unicode__(self):
return self.tag
class Image(models.Model):
title = models.CharField(max_length = 60, blank = True, null = True)
image = models.FileField(upload_to = get_upload_file_name)
tags = models.ManyToManyField(Tag, blank = True)
albums = models.ForeignKey('Album')
width = models.IntegerField(blank = True, null = True)
height = models.IntegerField(blank = True, null = True)
created = models.DateTimeField(auto_now_add=True)
How I am getting these album titles is with this method
def albums_(self):
lst = [x[1] for x in self.albums.values_list('albums')]
return ", ".join(lst)
However it is not working correctly. I am not sure how to fix this method.
How can I display the album title to the appropriate image?
class ImageAdmin(admin.ModelAdmin):
search_fields = ["title"]
list_display = ["__unicode__", "title", "tags_", "albums_", "created"]
list_filter = ["tags", "albums"]
admin.site.register(Image, ImageAdmin)

admin layout for Gallery app
I want to create me admin like this: http://lightbird.net/dbe/_static/p1.png What I have right now is: def get_upload_file_name(instance, filename): new_file_path_and_name = os.path.join(MEDIA_ROOT,'img/albums') return new_file_path_and_name class Album(models.Model): title = models.CharField(max_length = 60) def __unicode__(self): return self.title class Tag(models.Model): tag = models.CharField(max_length = 50) def __unicode__(self): return self.tag class Image(models.Model): title = models.CharField(max_length = 60, blank = True, null = True) image = models.FileField(upload_to = get_upload_file_name) tags = models.ManyToManyField(Tag, blank = True) albums = models.ForeignKey(Album) width = models.IntegerField(blank = True, null = True) height = models.IntegerField(blank = True, null = True) created = models.DateTimeField(auto_now_add=True) def tags_(self): lst = [x[1] for x in self.tags.values_list()] return str(join(lst, ", ")) def albums_(self): lst = [x[1] for x in self.albums.values_list()] return str(join(lst, ", ")) def __unicode__(self): return self.image.name class AlbumAdmin(admin.ModelAdmin): search_fields = ["title"] list_display = ["title"] class TagAdmin(admin.ModelAdmin): list_display = ["tag"] class ImageAdmin(admin.ModelAdmin): search_fields = ["title"] list_display = ["__unicode__", "title", "tags_", "albums_", "created"] list_filter = ["tags", "albums"] admin.site.register(Album, AlbumAdmin) admin.site.register(Tag, TagAdmin) admin.site.register(Image, ImageAdmin) I'm not sure what an acceptable input for ImageAdmin's list_display. I'm following the lightbird (http://lightbird.net/dbe/photo.html) tutorial but since it's out of date, I'm making some of my own choices along the way. I'm not sure how to modify my tags_ and albums_ method to achieve the admin layout. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Possible Model Inheritance Issue? Error: [Model_Name] instance needs to have a primary key value before a many-to-many relationship can be used
I know this is a VERY VERY old thread but oh my god I love you, I was
having the same problem for the same reason and would have never imaged
that was why (though it makes sense). Took me a long time to finally find
this thread.

GET parameters in admin "add" model page
I noticed that django admin "add" page reads GET parameters and uses them as initial values in the form. However I was not able to pass DateTime values in this way. In particular if I try to pass a DateTime value I get a "server error". See http://stackoverflow.com/questions/23559771/django-admin-add-page-initial-datetime-from-get-parameters for more details. 1. is it possible to pass DateTime values this way? 2. isn't it a bug if a user is able to generate a server error by messing with GET parameters? thanks E. -- You received this message because you are subscribed to the Google Groups "Django users" group.
