Here's a simplified version of what I need to accomplish:
1 from django.db import models
2
3 class Category(models.Model):
4 name = models.CharField(maxlength=255)
5 def __str__(self):
6 return self.name
7 class Admin: pass
8
9 class Listing(models.Model):
10 name = models.CharField(maxlength=255)
11 def __str__(self):
12 return self.name
13 class Admin: pass
14
15 class Location(models.Model):
16 name = models.CharField(maxlength=255,core=True)
17 listing = models.ForeignKey(Listing,
edit_inline=models.STACKED, num_in_admin=1)
18 categories = models.ManyToManyField(Category, blank=True,
null=True)
19 def __str__(self):
20 return self.name
21 class Meta:
22 ordering = ['listing','id']
Now I have no problem using this model at all from the command line.
However, when I try to save a Listing and Location (the inline FK) with
the categories (M2MField) left BLANK, I get an empty SQL IN () clause
in my error on the POST:
Exception Value: ERROR: syntax error at or near ")" at character 113
SELECT "vendor_category"."id","vendor_category"."name" FROM
"vendor_category" WHERE ("vendor_category"."id" IN ())
The data is saved fine and I can refresh the page with a GET that
returns proper page. If a value is selected for the categories
(M2MField), then this does not occur.
I had this working in a previous revision of Django 0.95, but it broke
when I updated the revision I'm using.
Any ideas?
