Question
im working category and subcategories with the DataModel, all is fine in this part, but i need to use my category and subcategories in my Menu Nav, im try to use this Jquery menu , and im rendering my menu with subcategories, but im lost with rendering the subcategories in the way:
<ul>
<li>
<a href="#">Category</a>
<!--subcategories-->
<span>Subcategory 1 </span>
<span>Subcategory 2 </span>
...
</li>
....
....
</ul>
My problem: in the datamodel: with the 'self', i dont know how ill do a for in this case for make the subcategories (parent is the field himself)..
class Category(models.Model):
name = models.CharField(core=True, maxlength=200)
slug = models.SlugField(prepopulate_from=('name',))
parent = models.ForeignKey('self', blank=True, null=True, related_name='child')
description = models.TextField(blank=True,help_text="Optional")
Thanks
Solution
Get all top-level categories using something like
top_level_cats = Category.objects.filter(parent__isnull=True)
Then:
for tlc in top_level_cats:
#do the HTML for the top-level category
for clc in tlc.child.all():
#do the HTML for the children of clc
If you have multiple level categories, there'll need to be a recursive call in there somewhere, but this gives the basic gist.
