Question

在我的Branch模型中，它有一个银行详细信息。银行模型由许多模型共享。因此，我使用了多态关联。我想在Swagger UI中显示它。我不知道那是怎么回事？

如果我取消注释嵌套属性，则正确显示...

  ​        parameter do          
            key :name, 'bank_attributes[recipient]'     
            key :in, :formData
            key :description, 'Recipient'
            key :required, true
            key :type, :string 
          end
          parameter do
            key :name, 'bank_attributes[bank_name]'
            key :in, :formData
            key :description, 'bank name'
            key :required, true
            key :type, :string 
          end
          parameter do
            key :name, 'bank_attributes[account_no]'
            key :in, :formData
            key :description, 'bank account no'
            key :required, true
            key :type, :string 
          end
