Question

当我尝试运行specs时，我收到以下错误。

Failure/Error: user = User.find({id: 2856, authorization: token});
     NoMethodError:
       undefined method `scan' for #<Hash:0x00000004effe80>

以下是我的spec。

 #Spec for user find and current user
  context "when user exists" do    
    it "should find a user" do 
      user = User.find({id: 2856, authorization: token});
      expect(user.name).to eq("test")
    end      
  end

find方法仅在最后一个Rails版本中按id进行搜索，所以相反：

  context "when user exists" do    
    it "should find a user" do 
      user = User.find({id: 2856, authorization: token});
      expect(user.name).to eq("test")
    end      
  end

使用：

  context "when user exists" do    
    it "should find a user" do 
      user = User.where(id: 2856, authorization: token).first
      expect(user.name).to eq("test")
    end      
  end

或更好：

  context "when user exists" do    
    it "should find a user" do 
      user = User.where(authorization: token).find(2856)
      expect(user.name).to eq("test")
    end      
  end

未定义的方法`scan＆＃39;对于＃<hash：0x00000004effe80> </hash：0x00000004effe80>
