I'm having a little trouble tracking a down a small problem. My models
(which are working) look like this (with some of the boilerplate cut
out):
class Image(models.Model):
id = models.AutoField(primary_key=True)
pub_date = models.DateTimeField(blank=True)
caption = models.TextField(blank=True)
location = models.CharField(blank=True, max_length=150)
portfolios = models.ManyToManyField(Portfolio, db_table='set_image',
blank=True)
def __unicode__(self):
return u"%s | %s" % (self.caption, self.location)
class Meta:
db_table = 'image'
ordering = ('-pub_date',)
class Portfolio(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(blank=True, max_length=150)
description = models.CharField(blank=True, max_length=300)
class Meta:
db_table = 'sets'
def __unicode__(self):
return self.name
class ImagePort(models.Model):
# Merge table to add data (Rank for ordering) to many-to-many
relationship between Image and Portfolio
portfolio = models.ForeignKey(Portfolio, blank=False, default=None)
image = models.ForeignKey(Image, blank=False, default=None)
rank = models.IntegerField(null=True, blank=True)
class Meta:
db_table = 'set_image'
ordering = ('rank',)
and in an admin.py file I have:
class ImageAdmin(admin.ModelAdmin):
ordering = ['id']
filter_horizontal = ('portfolios',)
admin.site.register(Image, ImageAdmin)
This works fine even after upgrading to 1.0. But when I follow the new
docs and change my Image model's many-to-many definition to:
portfolios = models.ManyToManyField(Portfolio, through="ImagePort",
blank=True)
I lose the many-to-many portfolios with the nifty filter_horizontal in
the Image admin. I can get the admin.TabularInline interface by
following the docs, but like most people I really prefer the nifty
javascript version. If I try to add the portfolio with something like
fields=('portfolios',) in the ImageAdmin I get a template syntax error
complaining that the key 'portfolio' is not found.
Am I doing something obviously wrong?
