Hi.
First, can anybody recommend a few Websites that explain CakePHP
associations and provide tutorials and examples? I have read the
manual and a couple other Websites, but I am still having problems
understanding the concepts.
Second, I need help with figuring out the association between two
models, Team and Game. They are part of a basketball league Website I
am building. I believe the appropriate association between the models
is hasAndBelongsToMany, but I could be wrong. I set the
$hasAndBelongsToMany variable in both models (see listing below) and I
also setup the teams_games database which contains the fields team_id
and game_id.
In my controller I call $this->set('gamesdata', $this->Game-
>findAll()), I don't get anything in the Team array (see results
listing below) and I get an error when I try to access the teams data
in my view. Can anyone tell me what I'm doing wrong. Please let me
know if more information is needed.
