this solution doesn't fit with my project i have to explain :
the table MANDATES contain the list of possible mandates like : (0,mayor,city) (1,deputy mayor,city) (2,minister,state) (3,king,state) this list use by me to make a form where the user of my program can select the mandate related by user the table ELECTED contain the relation between user and mandate like : (0,John Smith,mayor,Chicago) (1,Brad X,mayor,New York) (2,Adrien Y,king,Brasil) (3,Anton Z,minister,Great Britain) NB: i replace user_id,mandate_id,place_id by user.name, mandate.name,place.name the solution which i see to do that are : 1)i have explain in the first post 2) duplicate the field place_type in the table ELECTED (maybe it is the easier solution?) 3) group tables MANDATES and ELECTED like that : MANDATES - id - name - place_id - place_type - user_id in that way i create all possible mandates with no user related to make the form and when i have a relation between user/mandate i create a copy of the mandate with the user_id what do you think about this solution? thanks adrien On Jun 28, 5:12 pm, Marnen Laibow-Koser <rails-mailing-l...@andreas- s.net> wrote: > Adrien Nom wrote: > > I want to do that way because i must save the possible mandates in one > > table. > > That's not a good rationale.
