I am really having a hard time to solve this problem. Trying to make pagination by using vuex. But I can't update actions when I change the argument value.
For example to go to the next page, I tried a simple way
in component: home
<button #click="nextPage()">{{currentPage}}</button>
I send the argument to actions.
mounted(){
this.$store.dispatch('bridalApi', {currentPage})
},
data(){
return {
currentPage: 1,
};
},
methods: {
nextPage(){
this.currentPage++
}
},
in store.js
I take the argument that I commited.
actions: {
bridalApi({commit}, currentPage){
axios.get("api/bridal?page=" + currentPage)
.then(response => {
commit("setBridals", response.data);
})
.catch(e => {
console.log(e);
})
},
}
it's clearly I can't update the argument inside actions. Because when I click the button, it doesn't go to next page. I mean currentPage inside actions doesn't updated. This was the first way. So, I tried different approach to solve this problem which is like below.
in component: home
<button #click="nextPage()">{{pager}}</button>
I set/get the currentPage, and change the state.
methods: {
nextPage(){
this.pager++
}
},
computed: {
...mapGetters([
"getBridals",
]),
pager: {
set(val){
this.$store.commit("setPagination", val);
},
get(){
return this.$store.state.bridal.pagination.currentPage;
}
},
bridals() {
return this.getBridals;
},
},
in Store.js
state: {
bridals: [],
pagination: {
currentPage: 1,
},
},
mutations: {
setBridals(state, bridal){
state.bridals = bridal;
},
setPagination(state, pager){
state.pagination.currentPage = pager;
},
},
getters: {
getBridals(state){
return state.bridals
},
},
actions: {
bridalApi({commit,state}){
console.log(state.pagination.currentPage)
axios.get("api/bridal?page=" + state.pagination.currentPage)
.then(response => {
commit("setBridals", response.data);
})
.catch(e => {
console.log(e);
})
},
}
But this way is not working either. And I am very much out of ideas. How can I update the actions? What is the right way to use vuex for pagination?...
I am not sure is it's the right way to this. But solved it. Used the first way I mentioned in the question and update home component like below.
data(){
return {
currentPage: 1,
};
},
watch: {
currentPage() {
this.$store.dispatch("bridalApi", this.currentPage);
console.log("ok")
}
},
You can use a mutation for this like
state:{
data:[]
}
mutations:{
SET_DATA:(state , data) => {
return state.data = data
}
}
actions: {
dataApi({commit}, currentPage){
console.log(currentPage)
axios.get("http://website.com/api/endpoint?page="+currentPage)
.then(response => {
commit('SET_DATA' , response.data)
})
.catch(e => {
console.log(e);
})
}
}
I would recommend using LaravelVuePagination package for this.
That way you can have something like:
<pagination :data="bridals" #pagination-change-page="getBridals"></pagination>
export default {
name: 'BridlaList',
mounted() {
this.getBridals();
},
methods: {
getBridals(page = 1){
this.$store.dispatch('getBridals',{
page: page
});
},
}

Goal: Initially load posts using the Wordpress Rest API via Axios once in a Vue View, and only once during a session of visiting the Vue website.
Current Result: I currently fetch the results successfully and set them in sessionStorage. They display correctly. I want to know/learn if I am accomplishing this correctly and have the process optimized in the best way possible. I've looked up documentation and I think I have it down.
Current Code:
<script>
import Hero from "#/components/Hero.vue";
import axios from "axios";
export default {
name: "About",
components: {
Hero,
},
data: function() {
return {
eatery: [],
};
},
created() {
axios
.get("//localhost:81/wp-json/wp/v2/posts?_embed&per_page=5&categories=2")
.then((response) => {
sessionStorage.setItem("eatery", JSON.stringify(response.data));
})
.catch((error) => {
window.alert(error);
});
},
mounted() {
if (sessionStorage.getItem("eatery")) {
this.eatery = JSON.parse(sessionStorage.getItem("eatery"));
}
},
};
</script>
I would check whether it's in the storage before trying to load it. In your case, it would look like this:
export default {
name: "About",
components: {
Hero,
},
data: function() {
return {
eatery: [],
};
},
loadEatery() {
axios
.get("//localhost:81/wp-json/wp/v2/posts?_embed&per_page=5&categories=2")
.then((response) => {
sessionStorage.setItem("eatery", JSON.stringify(response.data));
return response.data;
})
.catch((error) => {
console.error(error); // for debugging maybe
});
},
mounted() {
if (sessionStorage.getItem("eatery")) {
this.eatery = JSON.parse(sessionStorage.getItem("eatery"));
} else {
loadEatery().then(data => this.eatery = data);
}
},
};
I'm making an app that has advanced search api.
You can choose what to look for and how to sort the results. The problem is that the page (vue-router) is updated only when the request changes, but it also should be updated when you change the search terms
How i can do this? I don't even have any ideas.
There is my code that is responsible for requesting the API and updating the router when the request is updated
export default {
name: "Search",
data: function () {
return {
selectedTag: 'story',
selectedBy: '',
};
},
components: {
'Item': Item
},
mounted() {
this.items = this.getItems(this.id)
},
beforeRouteUpdate(to, from, next) {
this.items = this.getItems(to.params.id);
next();
},
methods: {
getItems(id) {
this.items = this.$store.dispatch('FETCH_SEARCH_RESULTS', {id, tag: this.selectedTag, by: this.selectedBy});
return this.items;
},
},
created: function () {
this.getItems(this.$route.params.id);
},
computed: {
items: {
get() {
return this.$store.state.searchResults;
},
set(value) {
this.$store.commit("APPEND_SEARCH_RESULTS", value);
}
}
}
}
I am trying to return article ID and go the detail page for that id. I did something like below. But in the end it's not working... in the console there is an error popping up and pointing that:
api/v1/article[object%20Object]:1 Failed to load resource: the server
responded with a status of 404 (Not Found)
I need some help because I am a bit lost here... What I am missing here? what I do wrong?
Vuex
export const articles = {
state: {
article: {},
},
mutations: {
setArticle(state, article){
state.article = article;
},
},
getters: {
loadArticle(state){
return state.article;
},
},
actions: {
getArticle(id){
axios.get("api/v1/article" + id)
.then(response => {
this.commit('setArticles', response.data);
})
.catch(error => {
console.log(error);
})
},
}
}
Routes
{
path: "detail/:id",
name: "detail",
component: Vue.component("Detail", require("./pages/Detail.vue").default),
meta: {
requiresAuth: true
}
},
Article Component
export default {
components: {
maps,
},
data(){
return {
};
},
created(){
this.$store.dispatch( 'getArticle', {
id: this.$route.params.id
});
},
computed: {
article(){
return this.$store.getters.loadArticle;
}
}
}
Link to the article id
<router-link :to="{ name: 'detail', params: { id: item.id } }">詳細を見る</router-link>
Update
First parameter to store action is the store properties itself. This is the reason you get the store object. You need to receive id or any payload as second parameter.
actions: {
getArticle({ commit }, id){
axios.get("api/v1/article" + id)
.then(response => {
commit('setArticles', response.data);
})
.catch(error => {
console.log(error);
})
},
}
Here you see this
created(){
this.$store.dispatch( 'getArticle', {
id: this.$route.params.id
});
},
You are passing an object as parameter-
{
id: this.$route.params.id
}
You should be doing this instead -
created(){
this.$store.dispatch( 'getArticle', this.$route.params.id);
},
I have two functions in my store, one that gets data by calling API and one that toggles change on cell "approved". Everything working fine, except that when I toggle this change it happens in database and I get the response that it is done but It doesn't update on UI.
I am confused, what should I do after toggling change to reflect change on UI, should I call my API from .then or should I call action method responsible for getting data from server.
export default {
state: {
drivers: {
allDrivers:[],
driversError:null
},
isLoading: false,
token: localStorage.getItem('token'),
driverApproved: null,
driverNotApproved: null
},
getters: {
driversAreLoading (state) {
return state.isLoading;
},
driverError (state) {
return state.drivers.driversError;
},
getAllDrivers(state){
return state.drivers.allDrivers
}
},
mutations: {
getAllDrivers (state) {
state.isLoading=true;
state.drivers.driversError=null;
},
allDriversAvailable(state,payload){
state.isLoading=false;
state.drivers.allDrivers=payload;
},
allDriversNotAvailable(state,payload){
state.isLoading=false;
state.drivers.driversError=payload;
},
toggleDriverApproval(state){
state.isLoading = true;
},
driverApprovalCompleted(state){
state.isLoading = false;
state.driverApproved = true;
},
driverApprovalError(state){
state.isLoading = false;
state.driverError = true;
}
},
actions: {
allDrivers (context) {
context.commit("getAllDrivers")
return new Promise((res,rej)=>{
http.get('/api/admin/getAllDrivers').then(
response=>{
if (response.data.success){
let data=response.data.data;
data=data.map(function (driver) {
return {
/* response */
};
});
context.commit("allDriversAvailable",data);
res();
}else {
context.commit("allDriversNotAvailable",response.data)
rej()
}
})
.catch(error=>{
context.commit("allDriversNotAvailable",error.data)
rej()
});
});
},
toggleDriverApproval (context, payload){
return new Promise((res, rej)=>{
http.post("/api/admin/toggleDriverApproval",{
driver_id: payload
})
.then( response => {
context.commit('driverApprovalCompleted');
res();
}).catch( error =>{
context.commit('driverApprovalError');
rej()
})
})
}
}
}
and here is the code on the view, I wrote the necessary code for better clarification of the problem
export default {
name: 'Drivers',
data: () => ({
data: [],
allDrivers: [],
driversErrors: []
}),
created() {
this.$store
.dispatch('allDrivers')
.then(() => {
this.data = this.$store.getters.getAllDrivers
})
.catch(() => {
this.errors = this.$store.getters.driverError
})
},
computed: {
isLoading() {
return this.$store.getters.driversAreLoading
}
},
methods: {
verify: function(row) {
console.log(row)
this.$store.dispatch('toggleDriverApproval', row.id).then(() => {
this.data = this.$store.getters.getAllDrivers
console.log('done dis')
})
},
},
}
if I understand your issue, you want the UI displaying your data to change to the updated data after making a post request.
If you are using Vuex you will want to commit a mutation, and use a getter display the data.
I am not sure how your post request is being handled on the server but if successful typically you would send a response back to your front end with the updated data, and commit a mutation with the updated data.
Example:
Make a Post request
toggleDriverApproval (context, payload){
return new Promise((res, rej)=>{
http.post("/api/admin/toggleDriverApproval",{
driver_id: payload
})
.then( response => {
context.commit('driverApprovalCompleted', response.data);
res();
}).catch( error =>{
context.commit('driverApprovalError', error.response.data);
rej()
})
})
}
If succesful commit the mutation
.then( response => {
context.commit('driverApprovalCompleted', response.data);
res();
})
response.data being your data you want to mutate the state with.
Mutation Example:
customMutation(state, data) {
state.driverApproval = data
}
Getter Example:
driver(state) {
return state.driverApproval
}
displaying the getter in a template
<template>
<div v-if="driver">{{driver}}</div>
</template>
<script>
import {mapGetters} from 'vuex'
export default {
name: Example,
computed: {
driver() {
return this.$store.getters.driver
},
// or use mapGetters
...mapGetters(['driver'])
}
}
</script>

I'm learning Vue and I've run into a problem where my data returns undefined from a computed method. It seems that the data is not computed by the time the component is mounted, probably due to the get request - wrapping my this.render() in a setTimeout returns the data correctly. Setting a timeout is clearly not sensible so how should I be doing this for best practice?
Home.vue
export default {
created() {
this.$store.dispatch('retrievePost')
},
computed: {
posts() {
return this.$store.getters.getPosts
}
},
methods: {
render() {
console.log(this.comments)
}
},
mounted() {
setTimeout(() => {
this.render()
}, 2000);
},
}
store.js
export const store = new Vuex.Store({
state: {
posts: []
},
getters: {
getPosts (state) {
return state.posts
}
},
mutations: {
retrievePosts (state, comments) {
state.posts = posts
}
},
actions: {
retrievePosts (context) {
axios.defaults.headers.common['Authorization'] = 'Bearer ' + context.state.token
axios.get('/posts')
.then(response => {
context.commit('retrievePosts', response.data)
})
.catch(error => {
console.log(error)
})
}
}
})
It is because axios request is still processing when Vue invokes mounted hook(these actions are independent of each other), so state.posts are undefined as expected.
If you want to do something when posts loaded use watch or better computed if it's possible:
export default {
created() {
this.$store.dispatch('retrievePost')
},
computed: {
posts() {
return this.$store.getters.getPosts
}
},
methods: {
render() {
console.log(this.comments)
}
},
watch: {
posts() { // or comments I dont see comments definition in vue object
this.render();
}
}
}
P.S. And don't use render word as methods name or something because Vue instance has render function and it can be a bit confusing.
