@user = User.find_by_user_name(user_name)
if !@user.business_admins.nil?
puts “Am here” @business_admin = @user.business_admins[0]
end
class User < ActiveRecord::Base
has_many :business_admins
end
class BusinessAdmin < ActiveRecord::Base
belongs_to :user
end
Here what i am trying, I am using Mozilla rest-client, basically here
the *
user_name* found in the User table, But i didn’t put that id in the *
BusinessAdmin*, So what the problem is when i run the code, this if
!@user.business_admins.nil? will return true, because am getting this
*“Am
here”
Have any issues with this model??..
*
Thankyou

I am not sure what you are saying. If you have user has_many
business_admins then @user.business_admins will never be nil. It may
be an empty array however. Perhaps you should be testing for the
array empty rather than nil.
has_many :business_admins
!@user.business_admins.nil? will return true, because am getting this
Basically, the BusinessAdmin doesn’t have that use_name’s id, then why this
checking happned?
First what relationships have you got between the models (has_many,
belongs_to or whatever)?
As I said last time, if user has_many business_admins then @user.business_admins will always (effectively) be an array, which may
be empty. It will never be nil.
By the way, you sent your last email to me instead of to the list.
Please make sure you reply to the list.

if !@user.business_admins[0].nil?*
puts “Am here” @business_admin = @user.business_admins[0]
