我有一个使用 RTK createEntityAdapter 从数据库获取数据的用户列表。
获取用户列表的API函数代码
public function index(){
$roles = Role::all();
$all_roles = [];
foreach ($roles as $key => $role) {
$obj_role = new \stdClass();
$obj_role->id = $role->id;
$obj_role->name = $role->title;
array_push($all_roles,$obj_role);
}
return response()->json([
'users' => User::with('roles')->paginate(10),
'roles' => $all_roles
]);
}
在上面的代码中，通过使用 RTK createEntityAdapter 在响应应用程序中获取用户和角色并显示列表
userSlice.js
import { createSlice,createEntityAdapter} from "@reduxjs/toolkit";
import { HTTP_STATUS } from "../../src/constants";
import { fetchUsers, deleteUsers, saveUser } from "services/userService";
const userAdapter = createEntityAdapter({
selectId: (user) => user.id,
})
const userSlice = createSlice({
name:'user',
initialState: userAdapter.getInitialState(
{ loading: false,
page: 1,
total_pages: null,
status: null,
message: null,
roles: []
} ),
reducers:{
pageByNumber: (state,{payload}) => {
state.page = payload.page
},
nextPage: (state, {payload}) => {
state.page = state.page++
},
previousPage: (state, {payload}) => {
state.page = state.page--
},
clear: (state) => {
state.status = null,
state.message = null
}
},
extraReducers: {
[fetchUsers.pending]: (state) => {
state.loading = true,
state.status = HTTP_STATUS.PENDING
},
[fetchUsers.fulfilled]: (state, {payload}) => {
state.loading = false,
state.page = payload.users.current_page,
state.total_pages = Math.ceil(payload.users.total/payload.users.per_page),
userAdapter.setAll(state, payload.users.data),
state.status = HTTP_STATUS.FULFILLED,
state.roles = payload.roles
},
[fetchUsers.rejected]: (state, {error}) => {
state.loading = false,
state.status = HTTP_STATUS.REJECTED,
state.message = error.message
},
[deleteUsers.pending]: (state) => {
state.loading = true,
state.status = HTTP_STATUS.PENDING
},
[deleteUsers.fulfilled]: (state, { payload }) => {
state.loading = false,
userAdapter.removeOne(state, payload.id)
},
[deleteUsers.rejected]: (state) => {
state.loading = false
},
[saveUser.pending]: (state) => {
state.loading = true,
state.status = HTTP_STATUS.PENDING
},
[saveUser.fulfilled]: (state, { payload }) => {
state.loading = false,
state.status = HTTP_STATUS.FULFILLED
if(!payload.errors){
userAdapter.addOne(state, payload.id),
state.message = payload.message
}
},
[saveUser.rejected]: (state,{error}) => {
state.loading = false,
state.status = HTTP_STATUS.REJECTED,
state.message = error.message
}
},
});
export const userSelectors = userAdapter.getSelectors(
(state) => state.user,
)
export const {pageByNumber, nextPage, previousPage,clear} = userSlice.actions
export default userSlice.reducer
用户/index.js
const roles = useSelector(state => state.user.roles);
const allUsers = useSelector(userSelectors.selectAll);
useEffect(() => {
dispatch(
fetchUsers(currentPage))
.then(unwrapResult)
.then((obj) => console.log(obj))
.catch((obj) => console.log({objErr: obj}))
}, [dispatch])
//listing HTML
{
allUsers.map((ls,index) => (
<tr key={ls.id}>
<td>{ls.id}</td>
<td>{ls.name}</td>
<td>{ls.email}</td>
<td>
{ls.status =="ACTIVE" ? <Badge color="success" pill>Active</Badge>:<Badge color="danger" pill>Inactive</Badge>}</td>

{ls.roles.map((role) => (
role.title+" "
))}

<td><Moment fromNow ago>{ls.created_at}</Moment> </td>

))

Create.prototype= {
handleClose: propTypes.func.isRequired,
show: propTypes.bool.isRequired,

export default Create;
当我使用 saveUser createEntityAdapter 添加新用户时，没有获取关系数据“角色”并出现错误
