Undefined method `stringify_keys'

Rails
1

Hello

I have a view for user registration but when i try to view this page i
get this error:

undefined method `stringify_keys’ for “username”:String

Here’s my registration.rhtml:

<% form_tag :controller => :user, :action => :register do %>

Username>/label>
<%= text_field_tag 'user', nil, 'username' -%>

Password
<%= password_field_tag 'user', nil, 'password' -%>

E-mail
<%= email_field_tag 'user', nil, 'email' -%>

<%= submit_tag 'Register' -%> <% end %>

What’s my problem and what does this error means? i’ve searched google
but couldn’t find enough info.

Thanks.

The error is coming from your “text_field_tag”, “password_field_tag” and
so on,

you’ll see it goes

text_field_tag(name, value = nil, options = {})

but you’re doing
“user”, nil “username”

it expects the 3rd argument to be a hash,
and it calls “stringify_keys” on the hash.

I think you mean to be using

textfield(“user”, “username”)
