我如何在我的控制器规范中获得一个view_context来测试活动模型序列化器?

I setup this UserSerializer

我设置这个UserSerializer

class UserSerializer < ActiveModel::Serializer
  attributes :id, :first_name, :last_name, :email, :abilities

  delegate :current_user, to: :scope
  delegate :current_client, to: :scope

  def abilities
    object.client_roles.where(client_id: current_client.id)
  end
end

and this from my ApplicationController

这是我的ApplicationController。

class ApplicationController < ActionController::Base   
  serialization_scope :view_context

  protected 
  def current_client
      ....

I put in the "delegate" code based on this railscast around 7:45

我在7:45左右根据这个railscast输入了“委托”代码

He then goes on to say that the downside is that the tests now need a view_context and gives a solution for using Test Unit.

然后他接着说，缺点是测试现在需要一个view_context，并给出了使用测试单元的解决方案。

When I run my specs I get one of two errors

当我运行我的规范时，我得到两个错误之一。

Failure/Error: get "show", :id => user.id, :format => :json      NoMethodError:        undefined method `current_client' for #<#:0x00000004f69f60>

失败/错误:获取“show”，:id =>用户。id:格式= >:json NoMethodError:未定义方法的current_client # < #:0 x00000004f69f60 >

or

或

Failure/Error: data.active_model_serializer.new(data, {:root => name}).to_json RuntimeError: UserSerializer#current_client delegated to scope.current_client, but scope is nil:

失败/错误:data.active_model_serializer。新(数据,{:根= >名称})。to_json RuntimeError: UserSerializer#current_client委托给范围。current_client，但范围为nil:

How do I provide the view_context in my controller specs?

如何在控制器规范中提供view_context ?

Thanks.

谢谢。

OK. My fault. I was calling the UserSerializer manually in my code later to do assertions. That's what was throwing the error. Fixed it just by adding:

好的。我的错。后来我在代码中手动调用UserSerializer来做断言。这就是抛出错误的原因。通过添加:

before(:each) do
  UserSerializer.any_instance.stub(:scope => controller)
end
