I wanted to add search to my Rails application. Here’s what I did.<\/p>\n
1. Search code to the controller, this controller was already built using a scaffold around a Table called “Words”:<\/p>\n
controllers\/words_controller.rb:<\/p>\n
\r\n def search\r\n @words = Word.where("word = ?",params[:id]) #all #find(params[:id])\r\n\r\n respond_to do |format|\r\n format.html # search.html.erb\r\n format.json { render json: @words }\r\n end\r\n end\r\n<\/pre>\nI added a view based around the index.html.erb already present. It’s basically identical:<\/p>\n
app\/views\/words\/search.html.erb<\/p>\n
\r\n<h1>Search results<\/h1>\r\n\r\n<table>\r\n <tr>\r\n <th>Word<\/th>\r\n <th>Definition<\/th>\r\n <th>Tags<\/th>\r\n <th><\/th>\r\n <th><\/th>\r\n <th><\/th>\r\n <\/tr>\r\n\r\n<% @words.each do |word| %>\r\n <tr>\r\n <td><%= word.word %><\/td>\r\n <td><%= word.tags %><\/td>\r\n <td><%= word.definition %><\/td>\r\n <td><%= link_to 'Show', word %><\/td>\r\n <td><%= link_to 'Edit', edit_word_path(word) %><\/td>\r\n <td><%= link_to 'Destroy', word, confirm: 'Are you sure?', method: :delete %><\/td>\r\n <\/tr>\r\n<% end %>\r\n<\/table>\r\n\r\n<br \/>\r\n\r\n<%= link_to 'New Word', new_word_path %>\r\n\r\n<% if session[:user_id] %>\r\n<%= button_to 'Logout', logout_path, method: :delete %>\r\n<% end %>\r\n<\/div>\r\n<div id="main" >\r\n<%= yield %>\r\n<\/pre>\nI added the following rule to config\/routes.rb:<\/p>\n
\r\nmatch ':controller(\/:action(\/:id))'\r\n<\/pre>\nWhich if I’ve understood it correctly sends any http:\/\/blah\/anycontroller\/action\/something to the anycontroller’s action method using something as a parameter (kind of).<\/p>\n
I can then do searches such as:<\/p>\n
http:\/\/localhost:3000\/words\/search\/wordtosearchfor<\/p>\n
Notes<\/h2>\n
Will need to add a html form to perform the search (somehow).
\nClearly not great if you’re code is returning a lot of search results.<\/p>\n","protected":false},"excerpt":{"rendered":"
