I quickly ran into problems when trying to create an ActiveRecord instance that overrode initialize like this:
class Email < ActiveRecord::Base
belongs_t开发者_开发百科o :lead
def initialize(email = nil)
self.email = email unless email.nil?
end
end
I found this post which cleared up why it is happening.
Is there anyway that I can avoid creation code like this:
e = Email.new
e.email = "info@info.com"
I would like to create and initialise my objects in one line of code preferably.
Is this possible?
e = Email.new(:email => "info@info.com")
ActiveRecord::Base#new also takes a handy block variation
email = Email.new do |e|
e.email = params[:email] unless params[:email].blank?
end
The suggestions of using the hash version in prior answers is how i typically do it if I don't want to put any logic on the actual assignment.
