Valid? is not working in Rails 2.2.2

Rails
1

Hey,

I have a problem regarding the validation in rails 2.2.2. In my model
User has these conditions.

validates_presence_of :user_name, :password, :email, :display_name
validates_uniqueness_of :email, :message => ’ Already Exists in the
System.’

When i run this in rails 2.0.2 its working fine.

Loading development environment (Rails 2.0.2)
?> user = User.new
user = User.new
=> #<User:0x20e4140 @new_record=true, @attributes={“user_name”=>nil,
“password”=>nil, “display_name”=>nil,
“email”=>nil,“created_on”=>nil,“modified_on”=>nil}>

user.valid?
user.valid?
=> false

But in 2.2.2 give error.

Loading development environment (Rails 2.2.2)
?> user = User.new
user = User.new
=> #<User id: nil, user_name: nil, password: nil, display_name: nil,
email: nil, created_on: nil, modified_on: nil>

user.valid?
user.valid?

validates_presence_of :user_name, :password, :email, :display_name

Hey Vipin, are you using the same application code for both Rails 2.0.2
and
2.2.2
execution of your tests. If so, did you update the configuration files
when
executing your application code against Rails 2.2.2?

It just seems like there are too many conditions being tossed at the
validation method from wherever you are setting up those variables.

Hi guys…

First of all Sorry … :frowning: . i had a plugin called gloc-1.1.0 in my
vender/plugin. That was causing the problem.

Thanks guys,
Vipin

Hi All,

My project was started in 1.2.6 then i upgraded to 2.0.2. Last week i
updated it into 2.2.2. Then i got this problem. Then i again moved it
back to 2.0.2 and it worked fine. These are the changes i have made in
my config files.

in env.rb :-
RAILS_GEM_VERSION = ‘2.2.2’ unless defined? RAILS_GEM_VERSION
config.time_zone = ‘UTC’
config.threadsafe!

database.yml:-
pool: 10
wait_timeout: 10

when i upgraded to 2.2.2, got a new file called new_rails_defaults.rb in
initializers folder.

I created a new project in 2.2.2 and connected to my original db. its
also working fine.
