Re: cannot get property value from User class

[Abe Voelker]

Give this a try:

get '/:nickname/feed' do

  user = User.first(:nickname => params[:nickname])

  if user

    @user_name = user.name

  else

    not_found 'unknown user'

  end

end

Hi,

I have a problem getting the user’s name property. What am I doing wrong? I’m going insane why it’s not getting the name:

NoMethodError at /sican/feed
undefined method `name' for #<Enumerator: User:find("sican")>

Here’s the get method (commented out are some other alternatives that I’ve tried):

get '/:nickname/feed' do 
  @user_name  = User.find(params[:nickname]).name
  #user = User.get(params[:nickname])
  #@user_name = user.name
end

 Here’s the User class:

class User
  include DataMapper::Resource
  property :id,         Serial
  property :uid,        String
  property :name,       String
  property :nickname,   String
  property :created_on, DateTime
  has n, :posts
end

Any ideas?

Thanks Abe, works great!

the get method needs the Serial or the Key (can be a list of args) as
you defined your key in the model.

in your case it is the id of the User.
