How to pass parameters between New and Create actions?

Question

I have a parameter in my url when linking to the New action. I need this parameter in the create action. How do you do it?

Answer 1

You may use a hidden field.

<input id="thing" type="hidden" value="<%= params[:thing] %>" />

Put that code in the new view.

Answer 2

我发现<input type="hidden" name="modal" value="true" />也有效。
