#Simple Search
This is a very basic Ruby on Rails app that uses a very simple search.
I'd been using Sunspot, a SOLR powered search gem, for my local database collections and realized that moving forward with some of my projects I need to have a better understanding/ grasp over my searching mechanism.
This is very basic:
-
I generated a new rails application
-
I created a simple scaffold
-
I added twitter-bootstrap-rails gem, therubyracer gem, and less-rails gem
-
I followed the bulk of the instructions suggested on this page: http://www.jorgecoca.com/buils-search-form-ruby-rails
The following are changes made from the original generated scaffold:
<!-- application.html.erb -->
<!DOCTYPE html>
<html>
<head>
<title>Bootsy</title>
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
</head>
<body>
<%= form_tag(comics_path, :method => "get", class: "navbar-form", id: "search-form") do %>
<div class="input-append">
<%= text_field_tag :search, params[:search], class: "span2", placeholder: "Search Comics" %>
<button class="btn" type="submit"><i class="icon-search"></i></button>
</div>
<% end %>
<%= yield %>
</body>
</html>#comic.rb
class Comic < ActiveRecord::Base
validates :name, presence: true, uniqueness: true
validates :summary, presence: true, uniqueness: true
validates :issue, presence: true, uniqueness: true
def self.search(query)
where("name like ?", "%#{query}%")
end
end#comics_controller
class ComicsController < ApplicationController
before_action :set_comic, only: [:show, :edit, :update, :destroy]
# GET /comics
# GET /comics.json
def index
if params[:search]
@comics = Comic.search(params[:search]).order("created_at DESC")
else
@comics = Comic.order("created_at DESC")
end
end
# GET /comics/1
# GET /comics/1.json
def show
end
# GET /comics/new
def new
@comic = Comic.new
end
# GET /comics/1/edit
def edit
end
# POST /comics
# POST /comics.json
def create
@comic = Comic.new(comic_params)
respond_to do |format|
if @comic.save
format.html { redirect_to @comic, notice: 'Comic was successfully created.' }
format.json { render action: 'show', status: :created, location: @comic }
else
format.html { render action: 'new' }
format.json { render json: @comic.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /comics/1
# PATCH/PUT /comics/1.json
def update
respond_to do |format|
if @comic.update(comic_params)
format.html { redirect_to @comic, notice: 'Comic was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: @comic.errors, status: :unprocessable_entity }
end
end
end
# DELETE /comics/1
# DELETE /comics/1.json
def destroy
@comic.destroy
respond_to do |format|
format.html { redirect_to comics_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_comic
@comic = Comic.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def comic_params
params.require(:comic).permit(:name, :issue, :summary)
end
end<% @comics.each do |comic| %>
<div class="comic">
<h1 class="comic-name"><%= link_to comic.name, comic %></h1>
<p class="comic-content"><%= comic.summary %>
</div>
<% end %>
<br>
<%= link_to 'New Comic', new_comic_path %>
From here I plan to look more closely at Railscast 343 and update this functionality to be PostGRES grounded search.
We'll see how that goes.
