如何在同一个 createSlice 的 reducer 中声明的 extraReducers 中调用操作

  • 772

我正在编写删除用户的功能。我希望仅在服务器获得肯定结果后才从客户端删除。

我怎样才能用下面的代码做到这一点?

import { createSlice, createAsyncThunk } from "@reduxjs/toolkit";
import { useDispatch } from "react-redux";
import useHttp from '../../../hooks/http.hook';


const initialState = {
    usersList: [],
    usersToDelete: [],
    usersLoadingStatus: 'idle',
    userDeletingStatus: 'idle',
}




export const fetchUsers = createAsyncThunk(
    'users/fetchUsers',
    (pageNum) => {
        const request = useHttp();
        return request(`/admin/users/?page=${pageNum}`);
    }
);

export const deleteUser = createAsyncThunk(
    'users/deleteUser',
    (id) => {
        const request = useHttp('DELETE');
        return request(`/admin/users/${298}`);
    }
)




const usersSlice = createSlice({
    name: 'users',
    initialState,
    reducers: {
        deleteUserOnClient: (state, action) => {
            console.log(action);
            console.log(`action in basic reducer`)
            state.usersList = state.usersList.filter(item => item.id !== action.payload.data.id);
        }
    },
    extraReducers: (builder) => {
        builder
            .addCase(fetchUsers.pending, state => {state.usersLoadingStatus = 'fetching'})
            .addCase(fetchUsers.fulfilled, (state, action) => {
                state.usersLoadingStatus = 'idle';  
                state.usersList = state.usersList.concat(action.payload.data);
            })
            .addCase(fetchUsers.rejected, state => {state.usersLoadingStatus = 'error'});
        builder
            .addCase(deleteUser.pending, state => {state.userDeletingStatus = 'deleting'})
            .addCase(deleteUser.fulfilled, (state, action) => {
                console.log(`action id in fulfilled promise ${action.payload.data.id}`)
                (deleteUserOnClient(action.payload.data.id));
                
                state.userDeletingStatus = 'idle';
            })
            .addCase(deleteUser.rejected, state => {state.userDeletingStatus = 'error'})
    }
});


const {actions, reducer } = usersSlice;
const {
    deleteUserOnClient
} = actions;


export default reducer;

    我找到了解决我的问题的方法。

    在 中创建所需的操作就足够了reducers,然后引用sliceName.caseReducers.actionName它并且一切正常。

    const usersSlice = createSlice({
        name: 'users',
        initialState,
        reducers: {
            deleteUserOnClient: (state, action) => {
                console.log(action);
                console.log(`action in basic reducer`)
                state.usersList = state.usersList.filter(item => item.id !== action.payload.data.id);
            }
        },
        extraReducers: (builder) => {
            builder
                .addCase(fetchUsers.pending, state => {state.usersLoadingStatus = 'fetching'})
                .addCase(fetchUsers.fulfilled, (state, action) => {
                    state.usersLoadingStatus = 'idle';  
                    state.usersList = state.usersList.concat(action.payload.data);
                })
                .addCase(fetchUsers.rejected, state => {state.usersLoadingStatus = 'error'});
            builder
                .addCase(deleteUser.pending, state => {state.userDeletingStatus = 'deleting'})
                .addCase(deleteUser.fulfilled, (state, action) => {
                    console.log(`action id in fulfilled promise ${action.payload.data.id}`)
                    usersSlice.caseReducers.deleteUserOnClient()    // THIS LINE
                    
                    state.userDeletingStatus = 'idle';
                })
                .addCase(deleteUser.rejected, state => {state.userDeletingStatus = 'error'})
        }
    });
    
    const { reducer } = usersSlice;
    
    export default reducer;
