Hello, everybody:  
I have made a “form\_for” in a view returns the attributes value of  
a “user” model, such as user.login, user.email, user.name, ect.  
However, now I wanna add a new , e.g. “code”, into the form\_for  
tag, and return it to next action. The question is this attribute  
doesn’t belong to “user” model, it is simply a string i would like to  
deliver to next action. Once I try this , it errors: undefined  
method `number’ for #User:0xb5924cac.  
Is the “form\_for” tag merely able to convey model’s attribute  
value?

# ================ \<% form\_for :user, :url =\> {:action =\> ‘create’} do |f| -%\> 6:

Protect Image:  
  
7: \<%= f.text\_field :code%\>

Try using \<%= text\_field\_tag “number” %\> instead of f.text\_field

Thanks! I used to conside text\_filed\_tag should be only used in  
“form\_tag”…
