Hello everyone,

First congrats the community for this awesome framework, I am really in love with it !

Lately, I encountered a strange problem, I explain it:

I have the follow models:

Model_Folder {

[.....]

protected static $_has_many = array(

'subfolders' => array(

'model_to' => 'Model_Folder',

'key_to' => 'parent_id',

'key_from' => 'id',

),

'translations' => array(

'model_to' => 'Model_Translation',

'key_to' => 'token',

'key_from' => 'transl_token',

'cascade_save' => true,

'cascade_delete'=> true

));

}

Model_Translation {

protected static $_properties = array(
'id',
'lang' ,
'token' , 'key' , 'value');

}

So, Model_Folder is related with its childrens (subfolders), and translations to translate some of its fields.

The problem is that when I fetch a single folders, if it is a deepest children (starting from the 4th level ), I get an exception from :

/orm/classes/model.php @ line 877

Call to a member function implode_pk() on a non-object

I can only say this is happening when I translate something of the folder and so the folder when fetching related translations throw this error.

If the folder has not translations I can fetch it without problem.

Also the other folders from 1st to 3rd level , if they have translations I can fetch them without problems.

It's a bit strange, some of you know why it's happening?

Hope you understand the problem , I am Italian , and maybe my english isn't good !

Sorry my error, I did not tested appropriately all cases, but now the problem happens with all subfolders . So briefly if I am getting a folder (only with translations) , which is children of another folder I get that error.

Can you change your ORM installation to 1.8/develop, and see if it still is a problem?

Harro

Also, relations always have to be defined both ways, and it looks like your Model_Translation doesn't have a belongs_to relation back to Model_Folder?

@Harro Verton You're right, Model_Translation has not the belongs_to relation.

I resolved changing ORM to 1.8/develop ! Thanks

I share, what I discovered about the behavior of this error.

When I was fetching the folder, in that case for editing it on the form, I was also selecting all folders to put inside a select menu, to choose one of them as parent of the folder I am editing on the form.

I tried to delete temporary the select of all the folders with all related childrens, and I was not getting the error, and translations were correctly fetched .

The case was: if the Folder had not translations I could query all the folders for the select menu, instead if I didn't query two times the Folder model , I could get the related translations.

So there was definitively a problem handling maybe twice the the two relations.
