ruby-on-rails model has-many belongs-to relationships
I’m still familiarizing myself with Rails and have a question in regards to a problem I’m trying to solve utilizing Rails 3.2. Here is a link to the few files in question where I assume my problem lies:https://gist.github.com/0fe5cf9093b21f4f632fI apologize if the code is really bad/adds a few things that don’t need to exist as I’m still trying to get used to how everything works as I go along.I want to have comments for each post that is made on my website – and the logic I have is that users have many comments, and I suppose that the posts have many comments through the users.

Ok, so I thought I understood how the relationship specifications work in rails but I’ve been struggling with this for a day now.Some context, I have two models Cars & Model Names (e.g. Impala, Charger, etc), where Cars are instances of Model Names, and Model Names really is nothing more than a lookup table of Model Names and some other model level attributes. The Model Name controller is nested within the admin namespace as only admins can CRUD Model Names. End users can add instances of cars to

What is the right way to create a data model object so that I can create a form.

I need some help with CakePHP 2.2.3.What I have I have the following setup at the moment:Post hasMany AttachmentIt works fine and the page is generated with 2 queries:SELECT *, `Post`.`id` FROM `posts` AS `Post` WHERE 1 = 1 ORDER BY `Post`.`created` DESCSELECT `Attachment`.`id`, `Attachment`.`post_id`, `Attachment`.`created` FROM `attachments` AS `Attachment` WHERE `Attachment`.`post_id` IN (1, 2, 3, …, n) What I want I want to extend the relation to be as follows:Post hasMany Attachment; every Attachment belongsTo TypeAnd I don’t know hot to make CakePHP follow it. Basically, what I need is:SELECT *, `Post`.`id` FROM `posts` AS `Post` WHERE 1 = 1 ORDER BY `Post`.`created` DESCSELECT `Attachment`.`id`, `Attachment`.`post_id`, `Attachment`.`created`, `Type`.`title`, `Type`.`icon` FROM `attachments` AS `Attachment` LEFT JOIN `types` AS `Type` ON (`Attachment`.`type_id`=`Type`.`id`) WHERE `Attachment`.`post_id` IN (1, 2, 3, …, n) Note the LEFT JOIN types added.So I get the corresponding type data in the second query. I know I could get the data in a loop or using a ->query() call, but I want this to be as much effective and flexible as possible.The problemI tried the Containable, Model Unbinding trick (and this one) but no success.

Let’s say you wanted to find all the posts that contained a certain keyword (“magic”) or were created in the past two weeks, but you want to restrict your search to posts written by Bob:array (“Author.name” => “Bob”, “OR” => array (“Post.title LIKE” => “%magic%”,”Post.created >” => date(‘Y-m-d
