Question

I repeat this code many times. The only thing that changes is the name in conditions.

find(:all, :conditions => {:name => 'hans'}, :group => 'dato').map(&:klik)

I am trying to make some class method in the model. So I can keep it DRY.

I have been trying this and it is not working.

def self.grafdata(name)
    find(:all, :conditions => {:name => '(name)'}, :group => 'dato').map(&:klik)
end

ERROR: uninitialized constant ActionView::CompiledTemplates::Lars

I want to be able to write Model.grafdata(Hans), Model.grafdata(Lars)

Answer 1

I would simply add it as a function to your model:

class Model
  def self.grafdata(name)
    where(name: name).group('dato').map(&:klik)
  end
end

You can then call either of the following:

Model.grafdata('Lars')
Model.grafdata('Hans')
