Question about relations


#1

Hi

We get a little problem to do some relations between to Models :

First we have to Tables :

Roles :
id (pk)

c_type_role

Role_Action_Relations :
id (pk)

c_type_role_id

For one class of role (Roles.c_type_role) we can have many associated
permitted actions (Role_Action_Relations)

We would like to have a relation OneToMany between Roles and
Role_Action_Relations : the foreign key Roles.C_TYPE_ROLE would be
linked to Role_Action_Relations.c_type_role_id

As our columns don’t follow the convention for RoR, we’ve designed the
Models like this :

class Role < …
has_many :role_action_relation,
:finder_sql => ’ here the sql statement to get children rows from
Role_Action_Relations’
end

class Role_Action_Relation < …

end

My question is : Is there a simpler method to do this relation,
because we encounter some problems with the finder_sql option.

Thanks

Laurent
