匹配来自两个 api 调用的数据，然后在 React 中的 table 上显示结果

Question

我目前在我的应用程序中有两个 table，一个用于部门，一个用于员工。部门不与员工互动，但员工需要与部门互动。每个部门都有一个唯一的 ID，该 ID 在创建该部门时生成。还根据部门为员工分配该部门。我已经使用 useEffect 将员工和部门带入 Employee 组件

 useEffect(() => {
    if (employees.length === 0) {
      getEmployees();
      getDepts();
    }
  }, [employees.length, getDepts, getEmployees]);

getEmployees 和 getDepts 是对 firestore 的 api 调用。然后我将这些值传递给 table

     <EmployeeTable
              cat1={"Employee"}
              cat2={"Department"}
              cat3={"Status"}
              data={employees}
              departments={departments}
              setEdit={setDepartment}
              openEdit={setOpenEdit}
            />

然后我通过过滤后的结果进行映射

 filteredResults.map(data => {
  return (
   <tr key={data.id}>
    <td className="normalView">
     {data.default_department_id ? 
      data.default_department_id : "--None--"}
    </td>
   </tr>
 })

上面的代码吐出 default_department_id 但我不确定如何通过部门和员工编号进行过滤以匹配 id 并输出适当的部门名称

到目前为止我最接近的

  function getDeptId(employees) {
    var matchedDept = departments.filter(
      data => data.uid === employees.default_department_id
    );
    var namedDept = matchedDept.map(resp => {
      return resp.name;
    });
    console.log(namedDept);
  }

部门数据被传递为

Answer 1

departments.map(dept => {
return (
    <div>
        <h1>All of the employees at {dept.name} department</h1>
    {employees.map(employee => {
        return employee.default_department_id === dept.uid ? <p>{employee.first_name} works at {dept.name}</p> : ""
    })}
    </div>
)
})

不确定您是否试图在地图中对它们进行排序，但如果我理解正确的话，这应该可以解决问题。

或者，如果您正在过滤已过滤的员工。

filteredEmployees.map(employee => {
const worksAt = departments.find(dept => dept.uid === employee.default_department_id)
return (
    <div>
        My name is {employee.first_name} and I work at {worksAt.name}
    </div>
)
})
