I want to access state.session
in instance.js
from records_view.js
. How is this accomplished?
store/modules/instance.js
const state = {
// This is what I want to access in records_view.js
session: {}
};
const getters = {
sessionGetter: state => state.session
};
store/modules/records_view.js
const actions = {
getSettingsAction (context, props) {
// This is how I'm trying to access session, which doesn't work
let session = context.state.instance.session;
Api(
context,
{
noun: props.noun,
verb: 'GetRecordsViewSettings',
orgUnitKey: _.has(session, 'orgunit.key') ? session.orgunit.key : '',
data: {}
},
props.callback
);
}
};
This is for a little bit of added context.
store/index.js
import Vue from 'vue';
import Vuex from 'vuex';
import * as actions from './actions';
import * as getters from './getters';
import * as types from './mutation-types';
import instance from './modules/instance';
import recordsView from './modules/records_view';
Vue.use(Vuex);
export default new Vuex.Store({
state,
actions,
getters,
mutations,
modules: {
instance,
recordsView
}
});
state
references local state and rootState
should be used when accessing the state of other modules.
let session = context.rootState.instance.session;
Documentation: https://vuex.vuejs.org/en/modules.html
from an action :
'contacts:update' ({ commit, rootState }) {
console.log('rootState', rootState.users.form)
......
},
For me I had vuex modules, but needed a mutation to update STATE in a different file. Was able to accomplish this by adding THIS
Even in the module you can see what global state you have access to via console.log(this.state)
const mutations = {
MuteChangeAmt(state, payload) {
//From user module; Need THIS keyword to access global state
this.state.user.payees.amount = payload.changedAmt;
}
}
context.commit('user/change_amount', new_amount, {root: true})
In my case, this is how it worked for me.
In file ModuleA.js:
export const state = {
parameterInA: 'A'
}
export const action = {
showParameterB() {
console.log("Parameter B is: " + this.state.B.parameterInB)
}
In file ModuleB:
export const state = {
parameterInB: 'B'
}
export const action = {
showParameterA() {
console.log("Parameter A is: " + this.state.A.parameterInA)
}
You will need to import ModuleA & B in the index.js for the root:
import * as A from 'ModuleA.js'
import * as B from 'ModuleB.js'
This way, state parameter can be cross-referenced in sub modules.
this.$store.state.instance.session
where "instance" is the module name and "session" is the Vuex state variable you're trying to access.
Say you have two modules: ModuleA & ModuleB.
If you want to access ModuleA's state from ModuleB, you could do the following:
// inside ModuleB (where there is stateA in ModuleA)
getters: {
getStateA(state, _, rootState) {
return rootState.ModuleA.stateA;
},
},
You need to define session
in your state like following, to access it in your getters:
const state = {
session: ''
}
You have to write a mutation, which will be called from your actions to set this state value.
context.rootState.instance.session
