django1.2.4
I've got a document model
class Document(models.Model):
LANG_CODE = (
('B', 'Both'),
('E', 'English'),
('C', 'Cymraeg'),
)
title = models.CharField(max_length=100)
slug = models.SlugField(max_length=100,
unique_for_date='created_at')
created_at = models.DateTimeField('Date Published',
default=datetime.now, editable=False)
the_file = models.FileField(upload_to='files/documents/%Y-%m-%d/')
lang_code = models.CharField(max_length=1, choices=LANG_CODE,
default='B')
def __unicode__(self):
return u'%s' % self.title
def get_absolute_url(self):
url = u'/media/%s' % (self.the_file)
return iri_to_uri(url)
with a corresponding admin.py
class DocumentAdmin(admin.ModelAdmin):
fields = ('title','slug','the_file','lang_code')
list_display = ('title',)
search_fields = ('title',)
prepopulated_fields = { 'slug': ('title',) }
ordering = ('title',)
admin.site.register(Document, DocumentAdmin)
I've also got a Publications model, in which I can add Documents to a
publication
class Publication(models.Model):
title = models.CharField(max_length=255)
slug = models.SlugField(max_length=255, unique_for_date='pub_date')
title_c = models.CharField('Welsh Title', max_length=255)
slug_c = models.SlugField('Welsh Slug', max_length=255,
unique_for_date='pub_date')
created_at = models.DateTimeField('Date Published',
default=datetime.now, editable=False)
amended_at = models.DateTimeField('Date Modified', blank=True,
null=True)
pub_date = models.DateField('Publish Date')
body = models.TextField(help_text='Body')
body_html = models.TextField(blank=True, null=True)
body_c = models.TextField('Welsh Body', help_text='body_c')
body_c_html = models.TextField(blank=True, null=True)
the_file = models.FileField('Document', upload_to='files/documents/%Y-
%m-%d/', blank=True, null=True)
the_file_c = models.FileField('Welsh Document', upload_to='files/
documents/%Y-%m-%d/', blank=True, null=True)
tags = models.CharField(max_length=255, blank=True, null=True)
tags_c = models.CharField('Welsh tags', max_length=255, blank=True,
null=True)
image = models.ForeignKey(Photo,
limit_choices_to={'category__exact':'P'}, blank=True, null=True)
category = models.ForeignKey(Category, blank=True, null=True)
comments = models.BooleanField('Allow Comments', default=False)
documents = models.ManyToManyField(Document, related_name='pub_doc',
limit_choices_to = {'lang_code__in': ('B', 'E')}, blank=True,
null=True)
documents_c = models.ManyToManyField(Document, verbose_name="Welsh
Documents", related_name='pub_doc_c', limit_choices_to =
{'lang_code__in': ('B', 'C')}, blank=True, null=True)
Here's the admin.py of the publicaitons
class PublicationAdmin(admin.ModelAdmin):
fieldsets = (
(None, {'fields':
('title','slug','title_c','slug_c','category','pub_date','body','body_c','comments','image','documents','documents_c')}),
('Advanced options', {'classes': 'collapse', 'fields':
('tags','tags_c')}),
)
list_display = ('title','id','pub_date')
list_filter = ('pub_date','category')
search_fields = ('title','title_c')
prepopulated_fields = { 'slug': ('title',), 'slug_c': ('title_c',), }
ordering = ('title',)
date_hierarchy = 'pub_date'
When I'm in the admin backed and I'm adding a document to a
Publication, by selecting it from the box that displays the Documents
that you can add, I want to order of that List of Documents shown in
the box. I keep thinking I should be putting the ordering in the
ManyToManyField block in the documents description in the Publication
model, but I can't find a way to do that, so I'm starting to think
there is another solution.
Any help, as always, greatly appreciated.
