Search in Rails

Question

I have a table of \"posts\" with attributes that include title and body.

posts_controller.rb:

class PostsController < A         


        

Answer 1

For people coming here and looking for a solution in Rails 4, try the following example:

Posts Controller:

class PostsController < ApplicationController
  def index
    if params[:search]
      @posts = Post.search(params[:search]).order("created_at DESC")
    else
      @posts = Post.all.order('created_at DESC')
    end
  end
end

Post Model:

def self.search(search)
  # Title is for the above case, the OP incorrectly had 'name'
  where("title LIKE ?", "%#{search}%")
end

The index.html.erb remains the same apart from the search form:

<%= form_tag(posts_path, :method => "get", id: "search-form") do %>
  <%= text_field_tag :search, params[:search], placeholder: "Search Posts" %>
  <%= submit_tag "Search" %>
<% end %>

Note that the paths, controllers and columns you are using may be different.
