My ecommerce site has a models.py which defines 3 models. Originally, it had only defined two, Product and Category, but I realized I would need to be able to tag my products with certain keywords, and so I added that model. The problem arose when I tried to syncdb and the new tag table was created but NOT the products_tags 'through' table.
class Category(models.Model):
**a bunch of variables**
class Meta:
db_table = 'categories'
ordering = ['name']
verbose_name_plural = 'Categories'
def __unicode__(self):
return self.name
@models.permalink
def get_absolute_url(self):
return ('catalog_category', (), { 'category_slug': self.slug })
class Tag(models.Model):
**a bunch of variables**
class Meta:
db_table = 'tags'
ordering = ['name']
verbose_name_plural = 'Tags'
def __unicode__(self):
return self.name
class Product(models.Model):
**a bunch of variables**
categories = models.ManyToManyField(Category, related_name='cat+')
tags = models.ManyToManyField(Tag, related_name='tag+')
class Meta:
db_table = 'products'
ordering = ['-created_at']
def __unicode__(self):
return self.name
It all validates beautifully, and when I run python manage.py syncdb all the tables are created with the appropriate rows and types and everything else you would expect. Except, it doesn't create the products_tags table you would expect it to create because of the ManyToMany relationship established in the Product class. Why does it successfully create the products_categories 'through' table but not the products_tags one?
