Question

This is the error:

No route matches {:action=>"send_to_client", :controller=>"stages"}

It corresponds to this line:

<%= link_to "<span class='icon send-to-client-icon' title='Send to Client' id='send-to-client'> </span>".html_safe, send_to_client_stage_path(@stage), :id => stage.id, :confirm => "This will send #{stage.name.capitalize} to #{stage.client.email}. Are you sure you are ready?" %>

In this _show_table.html.erb

<%

if @upload != nil
    stage = @upload.stage
end

%>
<h1 class="panel-header">Images</h1>

<% if stage == nil %>
    <div class="images_menu">
        <%= link_to "<span class='icon send-to-client-icon' title='Send to Client' id='send-to-client'> </span>".html_safe, send_to_client_stage_path(@stage), :id => stage.id, :confirm => "This will send #{stage.name.capitalize} to #{stage.client.email}. Are you sure you are ready?" %>      
        <span class="icon compare-icon" data-url="<%= compare_stage_path(stage)%>" title="Compare Images" id="compare-images"> </span>
    </div>
<% end %>

Here is my routes.rb:

resources :stages do
    member do
      get :step
      get :compare
      get :send_to_client
    end
  end

The issue is that this partial _show_table.html.erb is in the view folder of my uploads model…not the stages model.

When I execute that link_to in the stages model, it works fine. Once I take it out into the uploads model it throws that error.

Why would that be the case ?

Edit1: Here is the send_to_client action of the stages controller:

def send_to_client
        stage = Stage.find(params[:id])
        ClientMailer.send_stage(stage).deliver
        if ClientMailer.send_stage(stage).deliver
            flash[:notice] = "Successfully sent to client."
            redirect_to("/")
        else
            flash[:notice] = "There were problems, please try re-sending."
            redirect_to("/")
        end
    end

Rails will raise an ActionController::RoutingError if you use send_to_client_stage_path(nil).

You’re mixing up @stage and stage. If you don’t define @stage in the controller action, it will be nil and the error raises. In this case, just use @upload.stage.

Like:

<% if @upload.stage %>
  <%= link_to "...", send_to_client_stage_path(@upload.stage), :confirm => "..." %>
<% end %>

If you want to use @stage, just define it in the action with @stage = @upload.stage and use it instead of @upload.stage:

<% if @stage %>
  <%= link_to "...", send_to_client_stage_path(@stage), :confirm => "..." %>
<% end %>
