I want to create text box but in run time

when I write in the controller for @a="input type ='text' " and in the view <%=@a%> it display text box in the page when it run

but when I write in the controller for @a="<%=text_field%>" and in the view <%=@a%> it doesn't display text box in the page when it run

how can i solve it

There are two problems with that. One, all that's going to do is output the text "text_field" not call the method. Second, text_field requires two arguments object_name and method.

So anyway, use the send method to call the text_field method in the view and pass in whatever args you need.

# Controller @a = 'text_field'

# View <%= send(@a, :object_name, :method) %>

Hope that helps.

How about creating a hidden DIV that include the text box, and make it appears programatically.
