will_paginate with search function is not working in ruby on rails

Question

I am trying to search my posts item with pagination. I am doing like this..

@posts = Post.search(params[:search]).paginate(page: params[:page],:per_page => 5)

But it showing NoMethodError

undefined method `paginate' for #<Array:0x9a93f08>

I don't know where i am wrong. Please help

Answer 1

I just change my code

@posts = Post.search(params[:search]).paginate(page: params[:page],:per_page => 5)

to this

@posts = Post.paginate(page: params[:page],:per_page => 5).search(params[:search])

Now it works fine :)

Answer 2

I will advise you to use Kaminari instead. As you can see by the Readme there's one section on to paginate Arrays. Also make sure you read the Kaminari recipes where is an example on paginate Arrays.

Answer 3

params[:search]) gives you an array. And Array don't have paginate method, so errors thrown up. Use p params[:search]).inspect to see the same.
