json-rpc에 의해 프론트 엔드가있는 커뮤니티 애플리케이션을 작성했습니다. ActiveRecord 클래스는 다음과 같습니다."저장"이 true를 반환하지만 데이터베이스에 무효 레코드가있는 이유는 무엇입니까?
class ProcessingDocument < ActiveRecord::Base
attr_accessible :command, :comment, :creator, :emergency_level, :file_name, :is_locked, :is_removed, :last_status, :next_status, :owner_id, :paper_title, :receiver, :sender, :status, :suggest, :unit_id, :uuid, :workflow_id
attr_accessor :command, :comment, :creator, :emergency_level, :file_name, :is_locked, :is_removed, :last_status, :next_status, :owner_id, :paper_title, :receiver, :sender, :status, :suggest, :unit_id, :uuid, :workflow_id
def self.all_propertoes
[:command, :comment, :creator, :emergency_level, :file_name, :is_locked, :is_removed, :last_status, :next_status, :owner_id, :paper_title, :receiver, :sender, :status, :suggest, :unit_id, :uuid, :workflow_id]
end
end
컨트롤러는 ProcessingDocument의 개체를 json으로 동적으로 업데이트합니다.
def pd_create(json)
pd_now = ProcessingDocument.new(:uuid => generate_uuid)
json["params"].each do |k, v| # the json["params"] is a Hash
if ProcessingDocument.all_propertoes.include? k.to_sym
pd_now.send("#{k}=", v)
else
render json: default_fail_json(json, __method__)
return
end
end
if pd_now.save
debug_method pd_now.to_json # this is a stdout bebug
result = { :uuid => pd_now.uuid }
render json: respond_data(json, result, nil)
else
render json: default_fail_json(json, __method__)
end
end

대단히 감사합니다! 하지만 Ruby의 attr_accessor와 Rails의 attr_accessible의 차이를 이해할 수는 없습니다. – Ghjhdf
이 두 가지 방법에 대해 많은 혼란이 있습니다. 실제로는 매우 다른 것들을합니다. 예 : http://stackoverflow.com/questions/4700785/using-attr-accessor-and-attr-accessible-on-the-same-field http://stackoverflow.com/questions/3136420/difference-between- attr-accessor-and-attr-accessible –
