Question

I have a voting system. When a user clicks “Vote” button, the vote value is incremented by one.

But the problem is, this increment action requires redirecting which I do not want to do.
I’m using will_paginate to paginate my records.
For e.g., if a user voted for an entity on page 2 of the paginated list, it should stay on page 2. But, currently, it redirects to page 1.

In view I have:

<ol>
    <% for number in @numbers%>
    <li>
        <%=number.value%>
        <%=button_to '+1',:action=>:increment,:id=>number.id,:remote=>true%>
        </li>
        <%end%>
        </ol>
        <%=will_paginate @numbers%>

In the controller I have:

def increment

        number=Digit.find(params[:id])
        number.increment!(:value)

    end

But when I don’t redirect, I get this error:

Missing template digits/increment with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths "c:/Sites/tester/app/views"

With your current solution, rails is looking for a view based on the method controller/method_name .

You need to insert a redirect_to after incrementing the number.

To redirect to the previous page, this is one solution:

     redirect_to :back
  rescue ActionController::RedirectBackError
     redirect_to root_path
