redux-toolkit 在另一个 thunk reducer 的同一切片中使用 actionCreater

Question

我有一个从 redux-toolkit 中用createSlice生成的 redux-thunk reducer，名为getOne。

getOne从 API 获取并调度加载状态的操作 (startedLoading、finishedLoading、errorLoading(。

我还想调用在同一切片中创建的另一个 actionCreater，称为insert与结果数据。 或者直接从getOne化简器更新状态。

import { createSlice } from "@reduxjs/toolkit"
import { startedLoading, finishedLoading, errorLoading } from '../slices/loadingSlice'
const apiEndpoint = "/api/v1"
const fetchOptions = { headers: { "Content-Type": "application/json" } }
const createModelSlice = function (modelName) {
return createSlice({
name: modelName,
initialState: {byId: {}},
reducers: {
insert: (state, action) => {
// ...
},
getOne: (state, action) => async (dispatch) => {
// ...
try {
const response = await fetch(/*  */)
// How would I update the store here?
// 1. reference the insert actionCreater somehow.
dispatch(insert({id: id, data: response))
// 2. construct the action manually
dispatch({action: `${modelName}/insert`, payload: {id: id, data: response))
// 3. Mutate the state here and rely immer. (I'm not sure exactly how that works)
state[modelName].byId[id] = response
dispatch(finishedLoading({ key: /* */ }))
} catch (error) {
dispatch(errorLoading({ key: /* */ }))
}
},
// ...
}
})
}

我错过了文档中关于切片无法使用 thunk 的部分。 无论哪种方式，它都不起作用，因为 thunk 操作不会映射到化简器，而是调度其他多个其他化简器/动作。

创建切片后，我向切片操作添加了 thunk 操作。 这样我就可以引用其他操作

import { createSlice } from "@reduxjs/toolkit"
const slice = createSlice({
name: name,
initialState: { byId: {} },
reducers: { /* */ }
}
slice.actions.myThunkAction = payload => async (dispatch, state) => {
// ...
slice.actions.nonThunkAction({ id: id, data: data})
slice.actions.anotherNonThunkAction({ index payload.index, data: data.map( /* */ )})
}

import { createSlice } from "@reduxjs/toolkit"
import { startedLoading, finishedLoading, errorLoading } from '../slices/loadingSlice'
import encodeURLParams from '../tools/encodeURLParams'
const apiEndpoint = "/api/v1"
const fetchOptions = { headers: { "Content-Type": "application/json" } }
const createModelSlice = function (modelName) {
const slice = createSlice({
name: modelName,
initialState: { byId: {} },
reducers: {
insert: (state, action) => {
// ...
},
bulkInsert: (state, action) => {
// ...
},
}
})
slice.actions.loadMany = payload => async (dispatch, state) => {
dispatch(startedLoading({ key: /* */ }))
try {
const response = await fetch(/*  */)
dispatch(slice.actions.insert(response))
dispatch(finishedLoading({ key: /* */ }))
} catch (error) {
dispatch(errorLoading({ key: /* */ }))
}
}
slice.actions.loadOne = payload => async (dispatch, state) => {
dispatch(startedLoading({ key: /* */ }))
try {
const response = await fetch(/*  */)
dispatch(slice.actions.bulkInsert(response))
dispatch(finishedLoading({ key: /* */ }))
} catch (error) {
dispatch(errorLoading({ key: /* */ }))
}
}
return slice
}
export default createModelSlice
