Question

I’m new to programming so please forgive me if this is a noob question!

I’m using Cake to build a blog, with the models users and entries.

I have a View page for the blog entries and I would like to add a list with all the other entries that its creator has written to it.

So what I need is for the find function in my entries controller to display only the entries with the same number as the foreign key “user_id” of the currently viewed entry.

Currently, in the entries controller I have added the following:

    $this->set('entries',
        $this->Entry->find('all', array(
            'conditions'=>array('Entry.user_id' => $id)
            )
        )
    );

So it takes the parameter of the view action, rather than its foreign key, which isn’t quite what I want.

But the problem is that I just can’t think of how to get the foreign key…

Hope you can help me out with that, thanks.

Answer 1

function view($id = null){
   if(!$id)$this->redirect(/*somewhere*/);
   $entry = $this->Entry->read(null,$id);
   $entries = $this->Entry->find('all', array(
            'conditions'=>array('Entry.user_id' => $entry['Entry']['user_id')
            )
        );
   $this->set(compact('entry','entries'));
}

You will need a certain degree of familiarity of Cake (don’t just blindly copy the code). Hopefully the above code will point you to the right direction.
