Missing template in RoR application

Question

In my ruby on rails application, I want to get controls value into controllers page:

    below is view page:
<%= form_for :managerviewresume, :url => { :method => :post, :action => :managerviewresume }) do |f| %>
        <table class="table" width="100%">
            <tr>
                <td><%= @selection %></td> //Here I am checking radio button value
                <td>
                    <label style="font-size:small;">Selected?</label>
                    <label class="radio inline" style="font-size: small">
                    </br>&nbsp;&nbsp;&nbsp;
                    <%= f.radio_button :select, "Yes", :id => "rb_select1" %>
                    Yes
                    </label>&nbsp;&nbsp;
                    <label class="radio inline" style="font-size: small">
                    <%= f.radio_button :select, "No", :id => "rb_select2" %>
                    No
                    </label>
                </td>
            </tr>
            <tr>
                <td>
                    <%= f.submit "Save", { :class => "stylbutton" } %>
                </td>
            </tr>
        </table> 
    <% end %>

below is controllers page:

class ManagersController < ApplicationController
  def managerviewresume
    @selection = params[:select]
    render "managerviewresumes"
  end
end

In the controller's page I am getting below error at this line render 'managerviewresumes' :

Missing template managers/managerviewresumes, application/managerviewresumes with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "C:/Sites/VideoResume/app/views" 

below is the route:

  match '/managerviewresumes',  to: 'managers#managerviewresume', via: 'get'

Kindly suggest what should I do get radio button value from view page into controller page. waiting for reply. Thanks.

Answer 1

Render

Firstly, you don't need to use render to render the same view as your action name

When using a Rails controller, you can call this without issue:

#app/controllers/your_controller.rb
Class YourController < ApplicationController
   def your_action
       #-> will automatically render the "your_action" view
   end
end

So I would remove your reference to the render action (as it is an unnecessary step). This will not resolve the issue directly, but should ensure your application is more convention over configuration

Routes

Secondly, you may need to look at resourceful routing

In Rails' routing structure, you are able to call resources :controller to generate a series of RESTful routes:

I understand you likely want to keep using your action, but for the sake of correctness, can I recommend you look into your config/routes.rb file & ensure you're using as many resource-based routes as possible:

#config/routes.rb
resources :managers do
   collection do
       post :managerviewresume
   end 
end

--

Form

Finally, I think your form needs to be improved

You're using form_for, which is mainly for ActiveRecord objects (if you want to create new record etc. It seems you'll be better suited to using form_tag instead:

<%= form_tag managers_managerviewresume_path do %>
    <table class="table" width="100%">
        <tr>
            <td><%= @selection %></td> //Here I am checking radio button value
            <td>
                <label style="font-size:small;">Selected?</label>
                <label class="radio inline" style="font-size: small">
                </br>&nbsp;&nbsp;&nbsp;
                <%= radio_button_tag :select, "Yes", :id => "rb_select1" %>
                Yes
                </label>&nbsp;&nbsp;
                <label class="radio inline" style="font-size: small">
                <%= radio_button_tag :select, "No", :id => "rb_select2" %>
                No
                </label>
            </td>
        </tr>
        <tr>
            <td>
                <%= submit_tag "Save", { :class => "stylbutton" } %>
            </td>
        </tr>
    </table> 
<% end %>

This syntax might need checking, but this will send the :select params as required, which is not what your current form will be doing.

This should be coupled with a views/managers/managerviewresume.html.erb file for Rails to load
