Rails search form submit to show method

controller, ruby-on-rails, search

Solution

Because it is not exactly a Restful show, you should create a new action, search.

#routes.rb
post 'search' => 'students#search'

#student_controller.rb
def search
   @student = Student.find_by_name params[:search_name]
   render action: 'show'
end

The form doesn't need to send the :id as far as I can tell.

<%= form_tag search_path, method: :get do %>
  <%= input_tag :search_name, type: 'text' %>
  <%= submit_tag "Search" %>
<% end %>

Problem

I am trying to set up a form in a Rails view to submit an id back to the show method in the controller. My form uses autocomplete to set the hidden id field: ``` <%= form_tag students_path, id: 'search_student_name', method: :get do %> <%= text_field_tag :search_name, '', size: 30 %> <%= hidden_field_tag :id %> <%= submit_tag "Search", name: nil %> <% end %> ``` I'm using the standard controller 'show' method generated by the scaffold: ``` # GET /students/1 # GET /students/1.json def show @student = student_scope.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @student } end end ``` I'd be grateful for any advice on the combination of form url / post method / additional routes to get this to work. Is this the way you'd normally do this is Rails, or should I set up a new controller method to handle the submitted form? Thanks in advance
