observe_form, rjs for form validate and a lot of mistakes!
First, thanks for reading this post!
Today i''m trying to implement a real-time form validator.
I have a model (user) within:
t.column :email, :string
t.column :name, :string
t.column :surname, :string
t.column :nickname, :string
t.column :gender, :integer
t.column :site, :string
t.column :birthday, :datetime
t.column :culinary, :string
t.column :avatar, :string
t.column :description, :string
t.column :password, :string
t.column :active, :boolean, :default => false
the validation rules:
validates_uniqueness_of :email, :nickname
validates_length_of :password, :within => 4..10
validates_length_of :email, :maximum => 50
validates_presence_of :name, :surname, :email, :password, :nickname
validates_format_of :email,
:with =>
/^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i # ( needs a improve )
and the controller code:
def signup
@title = "site_name: signup"
unless logged_in?
@user = User.new(params[:user])
if @user.valid? #@user.save
flash[:notice] = "user registered"
end
else
redirect_to :controller => "site_name", :action =>
"index"
end
end
And i wan''t to use XML (RJS), to validate in real-time what the user
type in
fields. If what was type can''t be allowed (see validate rules) a
message or
a red border indicates a error. I try several times, read a lot of articles
in google and see 4 railscasts.
Can anyone help me?
Obs.: sorry for my poor english.

In a nutshell if you use observe_form, an ajax request will submit the form whenever the fields change. In you controller you can cal User.new on those submitted parameter. In your rjs you can render the error messages (using error_messages_for or rolling your own) and insert them into a div (page.insert_html etc...)
