Hallo
I have the Problem that i give a parameter from the the Controller to
the view and then i want to give back that Parameter from the view to
the controller! But it doesn’t work. Please can somebody help me!

<% form_tag :action => :create do %>

<%=:id => @house.id, params[:id], size => 0%>
Bezeichnung <%= text_field_tag :name, params[:name], :size => 40 %><%= submit_tag "Hinzufügen" %>
<%end%>

In this code i want to give back @house.id from the view to the
controller!

Thank you

You should use a hidden_tag for this. “Giving back to the controller” is
done by posting http data to the controller.
