使用will_paginate和Rails时显示部分结果

Question

I am using will_paginate for the first time. My initial implementation is working great. Something like:

@products = Product.paginate(:page => params[:page], :per_page => 10)

In the Product controller, this produces what I was expecting, and I can flip through product listings fine. What I'm trying to do now is show only products that contain the word "glass", and can't figure out how to get it done. Any ideas?

Answer 1

Use a where clause like this (assuming @product.name should contain "glass"):

@products = Product.where('name LIKE ?', '%glass%').paginate(...)

Don't forget the paginate arguments, which I removed for clarity.

Answer 2

if you want to search word "glass" only from one perticular column you can use it as,

 Product.where("'coulumn_name' like ?","% glass %").paginate(:page => params[:page], :per_page => 10)

And if you want to search it from whole record then you can use fulltext search. check out: http://railscasts.com/episodes/370-ransack?view=asciicast and https://github.com/ernie/ransack

Gem Ransack provides full-text search.
