fActiveRecord::associate pluralisation / Help Please!

fActiveRecord::associate pluralisation

I'm not sure what's happening here, but it seems like flourish looks for the class name without taking pluralisation into account if it's given an array with only one member. For instance, if i do $groups→associateGroupFields($fields) but $fields is an array with a count of 1, it will cause a fatal "class GroupFields? not found" error, however if the array count is > 1, it recognises the pluralisation correctly and calls the GroupField? class.

for example, check out this trace: 

Fatal error: Class 'GroupFields' not found in /application/libraries/flourish/fORMRelated.php on line 107

and here's the creates for the tables…

For reference, this is from code gleened from this previous thread re: deep relations.

Any ideas here? It's got me stuck pretty bad.

    If i duplicate the models and create new ones like "GroupFields?" to try and get around the pluralisation issue, I just end up with a different exception claiming i have an invalidly formatted primary or unique key:

    is there something i'm missing here in my schema or something? i can't figure out what's going wrong here…

      I wanted to let you guys know that all issues with mapped classes should be resolved as of r792.

      I also updated the documentation about fORM::mapClassToTable() to recommend calling it in site-wide configuration and not in fActiveRecord::configure().

      uhm, ok… so… i rebuilt the database using single names rather than underscore notation, and changed the name of the classes so they're the exact, singular form of the database tables (i was using fORMmapClassToTable before), and now it works and i'm further confused.

      here are the new creates in case you can spot something here

      admittedly, i've been working on this all day so my brain my be a little run down. maybe all this data can help you figure this out, i'm just glad it's working :)

    I think it has to do with the fact that there is an associate for *-to-many relationships, but there is also an associate for one-to-one relationships. My guess is that the code I have right now probably isn't robust enough to handle mapped class names. I'll try to look into this soon - I'm just finishing up a major patch to Flourish.

      Same problem here.

      Just FYI, if i use mapped table names, for example for users and groups, both $user→associateGroup($one_group) and $user→associateGroups($groups_array) wont work.

      How can I associate user and groups in the meantime? should I make: $ref = new UserGroup?(), set user_id and group_id and then $ref→store() ?

        In another thread, there was some thought that calling fORM::mapClassToTable() for each model that needs table mapping in your init script rather than in the individual models' configure() methods might work.

          Yep I emmited that idea :) but in my case the association with mapped table names does not work even if the mapping is done
