我是編程界的新手,我喜歡它。不同角色的Query.FilterOperator
我對Query.Filter運算符有一些問題,由不同的角色。
- 管理 - 管理員可以查看所有留下的歷史
- 主管 - 主管可以在他查看自己和全體員工/她
- 員工 - 員工只能查看自己的休假歷史
從我做過的測試。管理員和員工工作正常,我面臨的問題是主管,主管能夠查看他/她下的員工,但無法查看自己的離開歷史。
這裏是代碼的一部分,感謝任何人都可以幫助我。謝謝

親愛的託尼,感謝您的建議,我已經測試了它,現在它成爲主管只能查看下他/她 – user1944535
自己的休假歷史,但沒有員工你能否請你檢查一下你的測試用例,你是否正在測試一個主管下沒有人的情況 –
