CONTEXT
I have two store modules : "Meetings" and "Demands". Within store "Demands" I have "getDemands" action, and within store "Meetings" I have "getMeetings" action. Prior to access meetings's data in Firestore, I need to know demands's Id (ex.: demands[i].id), so "getDemands" action must run and complete before "getMeetings" is dispatched.
Vuex documentation dispatching-action is very complete, but still, I don't see how to fit it in my code. There are also somme other good answered questions on the topic here :
I would like to know the best way to implement what I'm trying to accomplish. From my perspective this could be done by triggering one action from another, or using async / await, but I'm having trouble implementing it.
dashboard.vue
computed: {
demands() {
return this.$store.state.demands.demands;
},
meetings() {
return this.$store.state.meetings.meetings;
}
},
created() {
this.$store.dispatch("demands/getDemands");
//this.$store.dispatch("meetings/getMeetings"); Try A : Didn't work, seems like "getMeetings" must be called once "getDemands" is completed
},
VUEX store Module A – demands.js
export default {
namespaced: true,
state: {
demands:[], //demands is an array of objects
},
actions: {
// Get demands from firestore UPDATED
async getDemands({ rootState, commit, dispatch }) {
const { uid } = rootState.auth.user
if (!uid) return Promise.reject('User is not logged in!')
const userRef = db.collection('profiles').doc(uid)
db.collection('demands')
.where('toUser', "==", userRef)
.get()
.then(async snapshot => {
const demands = await Promise.all(
snapshot.docs.map(doc =>
extractDataFromDemand({ id: doc.id, demand: doc.data() })
)
)
commit('setDemands', { resource: 'demands', demands })
console.log(demands) //SECOND LOG
})
await dispatch("meetings/getMeetings", null, { root: true }) //UPDATE
},
...
mutations: {
setDemands(state, { resource, demands }) {
state[resource] = demands
},
...
Module B – meetings.js
export default {
namespaced: true,
state: {
meetings:[],
},
actions: {
// Get meeting from firestore UPDATED
getMeetings({ rootState, commit }) {
const { uid } = rootState.auth.user
if (!uid) return Promise.reject('User is not logged in!')
const userRef = db.collection('profiles').doc(uid)
const meetings = []
db.collection('demands')
.where('toUser', "==", userRef)
.get()
.then(async snapshot => {
await snapshot.forEach((document) => {
document.ref.collection("meetings").get()
.then(async snapshot => {
await snapshot.forEach((document) => {
console.log(document.id, " => ", document.data()) //LOG 3, 4
meetings.push(document.data())
})
})
})
})
console.log(meetings) // FIRST LOG
commit('setMeetings', { resource: 'meetings', meetings })
},
...
mutations: {
setMeetings(state, { resource, meetings }) {
state[resource] = meetings
},
...
