ruby on rails - Why do I get undefined method `each' allowing user the view own content? -

I am trying to get this work so that existing users can log in to see what they have posted I think that almost I have been cracked, but I got every error in an 'indispensable' method.

These are just two files I have edited:

_form.html.erb

 There are different models currently in my  program , which is the post of coach , And  coach  (user):  
 program.rb:  
  class program & lt; ActiveRecord :: Base is_to: Coach validates_presence_of: title attr_accessible: body ,: title ,: coach_id end   
 coach.rb:  
  class coach & lt; ActiveRecord :: Base has_many: Program # includes developing modules by default. Available: #: token_authenticatable, confirmable, #: lockable, timeoutable and: Omniauthable devise: database_authenticatable,: registerable, recoverable ,: memoryable, trackable, validatable # Setup accessible (or preserved) for your model attr_accessible: Email, password: password _confirmation: random, first name, last name: coach # attr_accessible: title, body end   
 If you need more details please let me know and I Give you   
 
 
 use  
  @programs   
 Or I think you should also change  
  current_coach [: id]   
 to  
  Current_coach.id
