Need correct GET request Ruby/Rails -

I am looking for the correct type of GET request:

In Route. :

  match 'my / render_block /: blockname',: controller = & gt; 'My',: Action => 'Render_block' ,: by = & gt; : Get, blockname = & gt; / \ W + /  

When I try:

 get : render_block,: blockname = & gt; 'Test'  

This error has been reported:

  ActionController :: routing error: no root matches {: controller = & gt; "Test" ,: user_id = & gt; 2}  

What is the correct marking of the GET request? In the end, the matching definition of this request with this regex seems a little strange to me.

thanks Ron
