Question

I’m new to CakePHP. Please help me to write a function to retrieve posts under a particular category for my blog app built using CakePHP.

My table structure:

posts: id, post, body, created, category_id
category: id, group

Also I had defined:
Inside post model – var $belongsTo = 'Category';
Inside category model – var $hasMany = 'Post';

Answer 1

find() is the generic query method for Models in CakePHP.

An example would be:

$results = $this->Post->find('recursive' => -1, 'conditions' => array('Post.category_id' => 1));
debug($results);

There are many ways to achieve what you want. I encourage you to read the docs or working through the CakePHP Blog Tutorial.
