Question

How can you pass all your params forward with a form_tag?

I’ve tried:

<%= form_tag(:controller => "users", :action => "index", :params => params) %>

<%= form_tag(:controller => "users", :action => "index", :params => params.except(:controller, :action)) %>

How should this work?

Answer 1

The helpers know that :params is special, so they won’t let you set it. Any other name will work fine…

<%= form_tag(:controller => "users", :action => "index", :p => params.except(:controller, :action)) %>

Update

Did you realize that even if you were able to set :params that it wouldn’t overlay on top of your params hash in your controller? It would have been params[:params] in your next request.

It has only just occurred to me that you might have been trying to do this…

<%= form_tag( params.merge( :controller => "users", :action => "index" )) %>
