Agreed that the user guide is excellent on Codeigniter.
However, there is no clear explanation of a complete, simple, CRUD model there - this is the best attempt at one available [I believe] and it is natural that people are trying to add the finishing touches.
It would be fabulous if the author could incorporate the corrections into the tutorial, as it is 98% there....

To the guys who are finding errors, read the CodeIgniter user guide! You must load models before trying to use them.

All of this (and much, much more) are explained in the user guide.

The user guide for CodeIgniter is one of it's great assets and the fact that so many people are neglecting to read it is shocking.

Ouch...I'm sorry i thought i was mistaken case. I have the same problem on line 17, then i add this

$this->load->model('posts_model');
$data['posts'] = $this->posts_model->getPosts();

I'm new in CI, so my question to the writer is:
do we need to add these lines before the operation model?

Very simple to fix - but tricky to debug without some prior knowledge.

You must "load" a model before you use it:

Amend the code in crud.php

// Add the post
$this->load->model('posts_model'); $this->posts_model->addPost($title, $content);

Broken tuts are a curse :(
