Question

我在Mongoid / Rails中有1-N关系：

class Company
  include Mongoid::Document

  field :name, type: String
  embeds_many :people, class_name: 'Person'
end

class Person
  include Mongoid::Document

  field :first_name, type: String
  embedded_in :company, class_name: 'Company', inverse_of: 'people'
end

现在，我可以在控制台中成功创建公司;例如：

> c = Company.new(name: 'GLG', :people => [{first_name: 'Jake'}])  # OK!
> c.people                                                         # OK!

然后我有一个JSON API控制器来更新公司，方法如下：

# PUT /api/companies/:id
def update
  if Company.update(company_params)
    # ... render JSON
  else
    # ... render error
  end
end

private

def company_params
  params.require(:company).permit(:name, :people => [:first_name])
end

现在，当PUT请求来自前端时，company_params总是缺少：people属性。 Rails日志说：

Parameters: {"id"=>"5436fbc64a616b5240050000", "name"=>"GLG", "people"=>[{"first_name"=>"Jake"}], "company"=>{"name"=>"GLG"}}

我没有收到“未经许可的参数”警告。我已经尝试了所有可以想象的方式来允许人员领域，但它仍然没有被包括在内。

params.require(:company).permit!

结果相同。我做错了什么？

Answer 1

您必须在转让时接受nested_attributes

 class Company
  include Mongoid::Document

  field :name, type: String
  embeds_many :people, class_name: 'Person'
  accepts_nested_attributes_for :people
end

Mongoid嵌入式文档和Rails强参数不起作用
