Question

I have a form <% form_for(@player) do |f| %> that displays the user’s password

<%= f.label :password %><br />
<%= f.text_field :password %>

I want to hide the password (just show a blank text box), and only update the password on submit if the text box is not blank. Would really appreciate any help.

Answer 1

In your player model (I’m assuming it’s the Player model that represents your user), this code does want you need:

# user will be able to edit her profile without providing password
validates_presence_of :password, :on => :create
validates_confirmation_of :password, :allow_blank => true

# you may also need to set the required length
validates_length_of :password, :within => 6..40, :allow_blank => true

And in your view, just use password_field instead of text_field. With password_field, you don’t have to set the value to an empty string.
