Im new to cakePHP and the whole table relations concept is very confusing!
I have 2 tables, competencies and competenceRatings. competencies stores a
list of names with ids.
competencies
------------
id
name
And users can select various competencies from this table and rate them and
their ratings are stored into competenceRatings table.
competenceRatings
-----------------
id
competence_id
user_id
rating
I want to be able to get the names of competencies for which a user have
NOT made any ratings into competenceRatings table. i.e., I need list of
names from competencies table for which there are no entries in
comptenceRatings table(for given user_id).
I tried competencies->hasMany->competenceRatings,
competenceRatings->belongsTo->competencies relations.
$competencies =
$this->Competence->CompetenceRating->find('all',array('CompetenceRating.user_id'
=> $userId,'CompetenceRating.competence_id !=' => 'Competence.id'));
But no use!
Does this result require any other relations? Or can i just join tables
using joins condition in find query?
Thanks.
