$q = Doctrine_Query::create()
->from(’Model_Db_Websites w’)
->leftJoin(’w.WebsiteMedia wm’)
->leftJoin(’wm.Media m’)
->orderBy(’wm.ordering ASC’)
;
That’s the query above.

Inside WebsitesBase setUp():

$this->hasMany(’Model_Db_WebsiteMedia as WebsiteMedia’, array(
‘local’ => ‘id’,
‘foreign’ => ‘websites_id’));

WebsiteMedia setUp() function:

$this->hasOne(’Model_Db_Media as Media’, array(
‘local’ => ‘media_id’,
‘foreign’ => ‘id’));

$this->hasOne(’Model_Db_Websites as Websites’, array(
‘local’ => ‘websites_id’,
‘foreign’ => ‘id’));

Okay, I have not see the DQL correctly.

Two point are confused to me.
The first, I want to select only some properties. But the select () isn’t working when I’m using the link-table like this;

The second point is that you use a relation “WebsiteMedia” that isn’t define in the WebsiteBase::setUp () function.

An optional point is, that the
orderBy (”wm.ordring ASC”); doesn’t change the result order. Why..

Not sure if that’s what you are asking, but as you are explicitly using WebsiteMedia (with the alias wm) you should be able to access the properties as say wm.ordering or wm.caption.

Don’t have the code at hand to check but I migth do a proper post about it later

Hi there,
Thank for this article.

I want to ask you just one question,
You have a many-to-many relationships between Media and Website.
The link-table have some property like “ordering”, “caption”…
The question is : “How do you proceed to order your result when you use the leftJoin on WebsiteMedia”.
Otherwise, How do you proceed to access on the properties of the link-table with DQL.

Thank,
Armetiz.

And what fixture file do you use for ts_website_has_media table?

Very nice example. Would it be possible to have all Media items loaded for a Website even if the linking WebsiteMedia record doesn’t exist (should give null values on ordering etc.)? This might seem odd in the current situation, however try to visualize it using User -> User_Setting -> Setting tables. Where Setting has a default_value.

Thank you soooooooooo much man (or girld or ROBOT) !!! I added the missing relation to the auto-generated aux table, and my dql query works perfect. :D:D:D
