Subject: Associations => through

Hello,
i have a little problem with the use of through in associations.
I have a correct link with has_many on a direct way, but i fail to use a has_many with through...

I worked on a simple study case : an user can have multiple projects.
So we have the following models : http://scrp.at/bd88901186f21970bad2d033e402bf92c572f13d

The first foreach is running well and i have the list but i link manually the three models.
The second fail and since this morning i did not find why... I read a lot of help topic to find another guy with the same problem but did not found a valid answer to solve my problem.

Actual Exception :

Fatal error: Uncaught exception 'ActiveRecord\HasManyThroughAssociationException'
 with message 'Could not find the association userstoproject in model user'
 in C:\wamp\www\test\lib\php-activerecord-20110425\lib\Relationship.php:491 
Stack trace: 
#0 C:\wamp\www\test\lib\php-activerecord-20110425\lib\Model.php(485): ActiveRecord\HasMany->load(Object(user)) 
#1 C:\wamp\www\test\lib\php-activerecord-20110425\lib\Model.php(333): ActiveRecord\Model->read_attribute('projects2') 
#2 C:\wamp\www\test\test.php(57): ActiveRecord\Model->__get('projects2') 
#3 {main} thrown in C:\wamp\www\test\lib\php-activerecord-20110425\lib\Relationship.php on line 491

PS: i did not use camelName because i fail more with them... x)
Maybe i will use them later when i will manage more this orm.

Regards, xTG.

Try to RTFM :-) http://www.phpactiverecord.org/projects/main/wiki/Associations#has_many_through

through matches a relation name, not a class name.

Pas de problème Baptiste, une fois que tu as pigé le truc c'est simple, jusque là il faut essayer/tester/…

Bonne continuation,

Tout à fait l'esprit oui. Le tout est que ça m'énerve un peu ce genre de souci...
Je l'avais lu et relue cette page, mais pas forcement au bon paragraphe. Et ma lecture est beaucoup trop approximative quand je survole...

Le plus simple (à mes yeux) est d'aller fouiner dans lib/Relationships.php pour comprendre comment ça fonctionne à coup de var_dump.
