producerRequirements: (-> 
    documentation = [] 
    types = @get('model.registrationsDocumentations'). 
       mapBy('producerType').compact().uniq() //first map by type 
    for producerType in types 
     requirements = @get('model.registrationsDocumentations'). 
          filterBy('producerType', producerType) //second filter by producerType 
     documentation.addObject(    //add to the array 
     producerType: producerType, 
     requirements: requirements 
    ) 
    documentation 
).property('model.registrationsDocumentations.@each')
