Hello people, I'm trying to get acquainted with GAE, and I'm stuck on
one simple problem:
I've got two classes in datastore: Category and Product:
class Category(db.Model):
name = db.StringProperty()
class Product(db.Model):
name = db.StringProperty()
shortdesc = db.TextProperty()
longdesc = db.TextProperty()
components = db.TextProperty()
image = db.BlobProperty()
thumbnail = db.BlobProperty()
category = db.ReferenceProperty(categories.Category)
When I'm editing product, in the form I do <select> to choose
category:
<select name='category'>
{% for cat in categories %}
<option value='{{ cat.key }}'>{{ cat.name }}</option>
{% endfor %}
</select>
BTW,
1. self.template_values['categories']=categories.Category().all().order
('name')
2. Codepage is utf-8
The problem is: when I'm posting product information, category ID is
not found. Printing catid shows correct ID, but query:
catid=self.request.str_POST['category']
cats=categories.Category.all().filter('__key__=',db.Key(catid))
returns 0 objects. "catid.decode('utf-8') doesn't help either.
Can anyone help me this? Thanks in advance.
