Thanks for your reply..
Each Acesso have a sector which is Unique. Acesso`s _unicode is
SECTOR.
When I set for the first time values for this rule(Acesso), the
dictionary come without values for genres.
Example:
Acesso is empty now.
Enter in Admin/Acesso
and set values:
Sector = 'Development'
Forbidden = 'Porn', 'Sports'
Free = 'News'
and save.
The dictionary should returns:
dic = {'Development': {'forbidden':['Porn', 'Sports'], 'free':
['News']}}
but return:
dic = {'Development': {'forbidden':[], 'free':[]}}
and return empty values for each new save.
I'm using postgresql.
