reload! doesn't reload

It also doesn't work with Rails 3.0.3 and ruby-1.9.2-p136

I couldn't reproduce this issue on master or 3.0.4:

# app/models/user.rb

class User < ActiveRecord::Base
  validates :email, :presence => true
  #validates :name, :presence => true
end

$ script/rails c
Loading development environment (Rails 3.1.0.beta)
irb(main):001:0> u = User.new
=> #<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>
irb(main):002:0> u.valid?
=> false
irb(main):003:0> u.errors
=> #<ActiveModel::Errors:0xb7204b50 @base=#<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>, @messages=#<OrderedHash {:email=>["can't be blank"]}>>

# Now, before reloading and without leaving the console, I uncomment the :name validation in the user model.

irb(main):004:0> reload!
Reloading...
=> true
irb(main):005:0> u = User.new
=> #<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>
irb(main):006:0> u.valid?
=> false
irb(main):007:0> u.errors
=> #<ActiveModel::Errors:0xb6d3ed00 @base=#<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>, @messages=#<OrderedHash {:email=>["can't be blank"], :name=>["can't be blank"]}>>

Sorry, in my last comment I previously confirmed the issue, but I was doing something wrong. I can't reproduce this issue and I updated my last comment.

Can anyone else reproduce this? If not, I'll mark this one as invalid. :)

Thanks Will, I tried to reproduce again:

# app/models/user.rb

class User < ActiveRecord::Base
  def reloaded?
    false
  end
end

$ script/rails c
Loading development environment (Rails 3.1.0.beta)
irb(main):001:0> u = User.new
=> #<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>
irb(main):002:0> u.reloaded?
=> false
irb(main):003:0> reload!
Reloading...
=> true
irb(main):004:0> u.reloaded?
=> false
irb(main):005:0> u = User.new
=> #<User id: nil, name: nil, email: nil, created_at: nil, updated_at: nil>
irb(main):006:0> u.reloaded?
=> true

Again, before calling reload!, I changed the model to make User#reloaded? return true. When I call that method on the existing u object, it still returns false after reloading. When I create a new User object, #reload? returns true.

This confirms your issue on master, I'll re-open the ticket and I'll have a look at it as soon as I can. :)

Hi William,

After talking to Josh about this, we came to this conclusion:

The u object doesn't get reloaded because it already existed before the model changed and reload! only takes care of the model in this case. I'm marking this one as wontfix, since reloading instances of objects is not reload!'s job, it simply reloads the environment.

Thanks for reporting! :)
