how to use v-model on vuex,
in this case only to show modal box when button is clicked
in this vuex also have separate to module
this is index module
import createPersistedState from 'vuex-persistedstate'
import Vue from 'vue'
import Vuex from 'vuex'
import authentication from './authentication'
import products from './products'
import projects from './projects'
Vue.use(Vuex)
export default new Vuex.Store({
strict: true,
state: {
baseUrl: '/api',
// baseUrl: 'http://localhost:3333/api',
},
mutations: {
},
actions: {
},
modules: {
authentication,
products,
projects,
},
plugins: [
createPersistedState(),
],
})
and this is my module
import HTTP from '../http';
export default {
namespaced: true,
state:{
dialog: false,
},
getters: {
dialog(state){
console.log(state.dialog)
return state.dialog
}
},
mutations: {
closeCard(state){
state.dialog=false;
console.log(state.dialog);
}
}
}
i have try map state and map getter both not function
and this is my vue code
v-model="dialog"
width="500"
i have try use map state or map getter but both not working
import Test from '/components/Test'
export default {
components:{
Test
},
computed: {
dialog:{
get() {
return this.$store.state.dialog.products
},
},
map State('products',[
'dialog'
]),
},
methods:{
map Actions('products',[
'close Card',
])
}
}
and this is my error
Computed property "dialog" was assigned to but it has no setter.

Directly binding a computed property to a v-model is a bad practice as a computed value doesn't have a default setter.
you will need to implement a setter for your computed value. you can read about it here.
you should implement a state action that changes the value of the dialog property and then call it in your setter (and set it to true or false, depending on the case.
Actually there are typo's in your code while called vuex handlers
import {mapState, mapActions } from 'vuex'; // check this line
import Test from '/components/Test'
export default {
components:{
Test
},
computed: {
dialog:{
return this.dialog;
},
...mapState('products',[ // check this line
'dialog'
]),
},
methods:{
...mapActions('products',[ // check this line
'closeCard', // check this line
])
}
}
Also note that you shouldn't directly bind a computed property to a v-model

I'll try and lay this out as cleanly as possible:
I have a Vue component that I'm rendering called World.vue:
<template>
<v-container>
This is the whole world
<v-btn #click="test()" />
</v-container>
</template>
<script>
import { mapState, mapActions } from 'vuex';
export default {
computed: {
...mapState('drawers', ['isEquipmentOpen']),
},
methods: {
...mapActions('drawers', ['test']),
},
};
</script>
And I have a module in for the Vuex store called drawers (drawers.js):
export default {
namespaced: true,
state: {
isEquipmentOpen: false,
},
actions: {
test(state) {
console.log(state.isEquipmentOpen);
state.isEquipmentOpen = !state.isEquipmentOpen;
},
},
};
What I don't understand is why when test() is called, it can't access isEquipmentOpen (logs a value of undefined). How can I manipulate isEquipmentOpen?
You cannot mutate state values from actions.
You'll need to create a mutations property, create a setter method in it
and call it in order to change the value.
Pass a { commit } parameter to method in actions property.
You don't need to pass the state parameter in actions methods.
Make sure that the string value in the commit() is the same as the setter name.
export default {
namespaced: true,
state: {
isEquipmentOpen: false,
},
actions: {
test({ commit }) {
console.log(state.isEquipmentOpen);
commit("setIsEquipmentOpen");
},
mutations: {
setIsEquipmentOpen: state => state.isEquipmentOpen != state.isEquipmentOpen
},
};
Hope you understood the answer!
I have a Vuex store like this. When triggering the storeTest action from my component with this.$store.dispatch("storeTest"); I need to use this weird syntax store.store to access an item.
import Vue from "vue";
import Vuex from "vuex";
Vue.use(Vuex);
export default new Vuex.Store({
state: {
loading: false,
fileStr: "data.json",
},
actions: {
storeTest(state) {
//works
console.log("state: ", state.state.fileStr);
//fail
console.log("state: ", state.fileStr);
},
},
},
});
I would expect I can access a state with state.item. Instead I have to write state.state.item. What could be wrong?
It's because actions do not receive state as a parameter, but context. You need it to dispatch other actions or to commit.
actions: {
async myAction ({ state, dispatch, commit }) {
console.log(state.loading);
await dispatch('anotherAction')
commit('someCommit')
}
}
Full list of the context properties here.
The first argument to an action function is not state, rather context (see docs).
This "context" object has various properties, one of which is state.
This differs from a mutation where the first argument is state.
refined and working thanks to #FitzFish
import Vue from "vue";
import Vuex from "vuex";
Vue.use(Vuex);
export default new Vuex.Store({
state: {
loading: false,
fileStr: "data.json",
},
actions: {
storeTest(context) {
//works
console.log("state: ", context.state.fileStr);
},
},
});
I'm trying to have a state that consists of namespaced modules and a global state. Unfortunately, I can access the global actions but I can't get the global state properties.
If I try to use mapState in a component like this,
computed: {
...mapState(['editMode']),
...mapState('address', ['addresses']),
}
I have access to addresses, but editMode is always undefined. Mapping actions works flawlessly and updates the state according to the Vuex Chrome Tool.
But I noticed, that the global state is shown under its own "namespace" "global". So I tried to map using ...mapState('global', ['editMode']), but got an error that the namespace does not exist.
Here's my code:
index.ts
import Vue from 'vue';
import Vuex from 'vuex';
import address from './modules/address';
import global from './global';
Vue.use(Vuex);
export default new Vuex.Store({
modules: {
address,
global,
},
});
modules/address.ts
export default {
namespaced: true,
state: {
addresses: [],
},
mutations: {
...
},
actions: {
...
},
};
global.ts
export default {
namespaced: false,
state: {
editMode: 0,
},
mutations: {
SET_EDIT_MODE(state, value) {
state.editMode = value;
},
},
actions: {
setEditMode({ commit }, editMode) {
commit('SET_EDIT_MODE', editMode);
},
},
};
State is not affected by namespace. In a way it always gets namespaced. This is so we don't have collision.
To access a state from a module you need to get a bit verbose:
computed: {
...mapState({
editMode: state => state.global.editMode
}),
...mapState('address', ['addresses']),
}
I'm following the sample code in the Vuex guide and I'm getting a weird result (at least for me).
Vuex Store
import Vue from "vue";
import Vuex from "vuex";
Vue.use(Vuex);
const store = new Vuex.Store({
state: {
name: ""
},
mutations: {
updateName(state, newName) {
state.name = newName;
}
},
getters: {
getName: state => state.name
}
});
export default store;
Component, inside the <script> tags:
import { mapGetters } from "vuex";
export default {
name: "Home",
data: function() {
return {
showingName: true
};
},
computed: {
...mapGetters(["getName"])
},
methods: {
getNameHandler() {
// eslint-disable-next-line
console.log(this.$store.getters.getname); // returns undefined
}
}
};
Here is a live sample:
https://codesandbox.io/s/yww774xrmj
Basically the question is, why the console.log returns undedined?. you can see that by clicking the button in the Home component. I'm following the same pattern as shown in the official Vuex guide:
https://vuex.vuejs.org/guide/getters.html#property-style-access
Unless I'm missing an import or a Vue.use(), but what gets my attention is that using the ´mapGetters´ actually allows me to use the getter as a computed property. You can change the name property of the state with the button in the About component.
The getter name is case-sensitive.
this.$store.getters.getName
You have
this.$store.getters.getname
First of all install the chrome plugin for vuex link.
Please check your mutations -> updateName is updating the state or not then you will get you're value from getters -> getName.
I hope that gonna help you out.
Thanks.
I'm new with vue.js and vuex and I've an issue with the mapstate object, first I've only one module in my store:
-Store
-index.js
-mutations.js
-actions.js
-state.js
state.js :
export default {
userInfo: {
messages: [{ 1: 'test', 2: 'test' }],
notifications: [],
tasks: []
}
}
So when I try to access the userInfo object everything works correctly:
computed: {
...mapState(["userInfo"]),
}
Then I decided to create modules:
-Store
-modules
-ldap.js
-commons.js
-index.js
So the userInfo is in the commons.js file and now when I try to get the object I always get undefined:
commons.js
// state
const state = {
userInfo: {
messages: [{ 1: 'test', 2: 'test' }],
notifications: [],
tasks: []
}
}
export default {
actions,
mutations,
state
}
Component.vue
computed: {
...mapState(["userInfo"]), // <---- undefined
}
main.js :
import Vue from 'vue'
import Vuex from 'vuex'
import commons from './commons'
import ldap from './modules/ldap'
Vue.use(Vuex)
export default new Vuex.Store({
modules : {
commons,
ldap
}
})
Can you tell me how to access the userInfo object?
Thanks.
Considering:
Your commons.js is as follows:
// state
const state = {
userInfo: {
messages: [{ 1: 'test', 2: 'test' }],
notifications: [],
tasks: []
}
}
export default {
namespaced: true, // <== make sure this is defined
actions,
mutations,
state
}
And main.js imports it like:
import commons from './commons'
// ..
export default new Vuex.Store({
modules : {
commons,
ldap
}
})
Then update on Component.vue:
import { mapState } from 'vuex'
// ...
computed: {
...mapState('commons', ["userInfo"]), // <== add module name here
}
Or
import { createNamespacedHelpers } from 'vuex'
const { mapState, mapActions } = createNamespacedHelpers('commons')
// ... notice module name above ^^^^^^^^^
computed: {
...mapState(["userInfo"]),
}
"[vuex] unknown mutation type: "
Since you are now namespacing your commons module, that modules' mutations now must be prefixed.
So, say you had a mutation like:
const mutations = {
changeName(state, data) {
state.name = data;
}
}
export default {
namespaced: true,
actions,
mutations,
state
}
And you used it like:
this.$store.commit('changeName', "New Name");
Now use it like:
this.$store.commit('commons/changeName', "New Name");
I guess you have namspaced your modules by adding namespaced: true in your module.
So you should pass the module name as the first argument to the mapState helpers so that all bindings are done using that module as the context. See Binding Helpers with Namespace
computed: {
...mapState('commons' , ["userInfo"])
}
You have to define each module as a individual store, here some pseudo example.
// authStore.js
import mutations from './authMutations'
import actions from './authActions'
import getters from './authGetters'
const initialState = {
...
}
export default {
state: initialState,
mutations,
actions,
getters
}
Then, register the modules
import authStore from './authStore'
const store = new Vuex.Store({
modules: {
{...authStore, namespaced: true},
{...postStore, namespaced: true} // some other module defined like auth
}
})
new Vue({
....
store: store
})
And then, on the component use it:
import { createNamespacedHelpers } from 'vuex'
// map state and actions of the module
const { mapState, mapActions } = createNamespacedHelpers('auth')
export default {
computed: {
...mapState({
prop1: 'prop1'
})
}
}
Vuex modules docs
It is really unclear in the documentation but namespaced: true is required to use the map functions.
At least as of the last comment in this discussion
https://github.com/vuejs/vuex/issues/855
Without the need to namespace your modules you can use the callback variant of mapstate:
computed: {
...mapState({
userInfo: state => state.commons.userInfo,
}),
},
