Adding search to a Rails app.
I wanted to add search to my Rails application. Here’s what I did.
1. Search code to the controller, this controller was already built using a scaffold around a Table called “Words”:
controllers/words_controller.rb:
1 2 3 4 5 6 7 8 | def search @words = Word.where("word = ?",params[:id]) #all #find(params[:id]) respond_to do |format| format.html # search.html.erb format.json { render json: @words } endend |
I added a view based around the index.html.erb already present. It’s basically identical:
app/views/words/search.html.erb
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | <h1>Search results</h1><table> <tr> <th>Word</th> <th>Definition</th> <th>Tags</th> <th></th> <th></th> <th></th> </tr><% @words.each do |word| %> <tr> <td><%= word.word %></td> <td><%= word.tags %></td> <td><%= word.definition %></td> <td><%= link_to 'Show', word %></td> <td><%= link_to 'Edit', edit_word_path(word) %></td> <td><%= link_to 'Destroy', word, confirm: 'Are you sure?', method: :delete %></td> </tr><% end %></table><br /><%= link_to 'New Word', new_word_path %><% if session[:user_id] %><%= button_to 'Logout', logout_path, method: :delete %><% end %></div><div id="main" ><%= yield %> |
I added the following rule to config/routes.rb:
1 | match ':controller(/:action(/:id))' |
Which 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).
I can then do searches such as:
http://localhost:3000/words/search/wordtosearchfor
Notes
Will need to add a html form to perform the search (somehow).
Clearly not great if you’re code is returning a lot of search results.
