my intention is to get some data from api,
then put in the head(){} to set description and title,
but it keep telling me val.replace is not a function,
here is my code
async mounted() {
...await call api...
if (resDataGetNewsInfo.return_code === 0) {
vm.newsInfoObj = resDataGetNewsInfo.return_msg;
} else {
...
}
...
asyncData() {
return {
newsInfoObj: '',
};
},
...
head() {
return {
description: this.newsInfoObj.news_short_desc,
meta: [
{
hid: 'og:title',
property: 'og:title',
content: this.newsInfoObj.news_title,
},
Uncaught TypeError: val.replace is not a function
thanks for answering
Thats not the way to use asyncData.
Your API call should be called inside the asyncData and then return your data

How do I solve this Vue Js error on Shopware 6 Administration. The module is suppose to select a column in the database table.
PS. This is the complete code. I'm trying to read data from the database and view it in the twig template.
const { Component, Mixin } = Shopware;
const { Criteria } = Shopware.Data;
import template from './store-settings-page.html.twig'
Component.register('store-settings-page', {
template,
inject: [
'repositoryFactory'
],
metaInfo() {
return {
title: this.$createTitle()
};
},
data: function () {
return {
entity: undefined,
storeData: null,
entityId: '4e2891496c4e4587a3a7efe587fc8c80',
secret_key: 'hdkkjjsmk538dncbjmns',
public_key: '1destinoDet2123lefmoddfk##$$%O',
}
},
computed: {
storeKeysRepository() {
return this.repositoryFactory.create('store_keys');
},
},
created() {
this.storeKeysRepository
.get(this.entityId, Shopware.Context.api)
.then(entity => {
this.entity = entity;
});
console.log(entity);
},
});
Apologies if my knowledge of Vue & JS is a bit off, based on how I see Shopware codes it, I recommend data to be written like this:
data() {
return {
...
};
}
I would also try to strip your file to the bear minimum to see when the error disappears.
Another thing to check is if you are running a JS file or TS file. Maybe it's having a hard time parsing your file because you are extending store-settings-page and it assumes it should be TypeScript?
this.storeKeysRepository
.get(this.entityId, Shopware.Context.api)
.then(entity => {
this.entity = entity;
console.log(this.entity);
});
This will do the trick
For some reason this was giving me trouble this morning, and I just couldn't figure out why it wouldn't work.
I have a variable 'applications' set equal to the data returned by my axios call. I want to include 'applications.name' as a field in my data() to send as a form. However when I try this, Vue gives me an error saying 'Cannot read property 'name' of undefined'.
{{applicants.name}} and {{applicants.role}} are working in the template, so I'm not just getting empty data
Also another thing, data() doesn't seem to recognize my 'this.loggedInUser.id' field either for some reason. (I've imported both Vuex and mapGetters)
Appreciate the help! :)
async asyncData({ $axios, params }) {
try {
let applicants = await $axios.$get(`/api/v1/apps/${params.id}/`);
return { applicants };
} catch (error) {
console.log(error);
return { applicants: [] };
}
},
data() {
return {
applicants: [],
application: {
name: this.applicants.name,
status: null,
company: null,
role: this.applicants.role
// user: this.loggedInUser.id
}
};
}
};
Try to pass this as parameter to the data property function:
data(vm) { //refers to this keyword
return {
applicants: [],
application: {
name: vm.applicants.name,
status: null,
company: null,
role: vm.applicants.role
// user:vm.loggedInUser.id
}
};
}
or make application as a computed property :
data() {
return {
applicants: [],
};
}
,
computed:{
application(){
return {
name: this.applicants.name,
status: null,
company: null,
role: this.applicants.role
// user: this.loggedInUser.id
}
}
}
I am assuming that when the data is initialized, the values applicants.name and loggedInUser.id do not exist. Try changing the data like this
data() {
return {
applicants: { name: '' },
application: {
name: this.applicants.name,
},
loggedInUser: { id: '' }
};
}
so I'm trying to get my Axios to do a get request with a param that'll end the url in
'/?user= {id}'
the id is passed in by my loggedInUser.id from Vuex. I know that async functions won't accept 'this' inside the call so I included store as a parameter. Something's still off with how I passed the data around thought I think. Would appreciate any help, thanks!
import { mapGetters } from "vuex";
export default {
computed: {
...mapGetters(["loggedInUser"])
},
head() {
return {
title: "Actors list"
};
},
components: {
EditProfile
},
async asyncData({ store }) {
try {
const body = { data: store.getters.loggedInUser.id };
const { actors } = await $axios.$get(`/api/v1/actors/`, {
params: {
user: body
}
});
return { actors };
} catch (e) {
return { actors: [] };
}
},
data() {
return {
actors: []
};
Edit
I got it to work when I removed the data: from 'const body' and removed the brackets as well around 'actor'
try {
const body = store.getters.loggedInUser.id;
const actors = await $axios.$get(`/api/v1/actors/`, {
params: {
user: body
}
});
You can access your params from Context.
Context is available in special nuxt lifecycle areas like asyncData, fetch, plugins, middleware and nuxtServerInit.
In Nuxt, with asyncData hook you can get query parameters from the route context key.
Please read the Nuxt.js Context documentation. The context provides additional objects/params from Nuxt to Vue components
With your-domain/?user=wonderman
asyncData({ route: { query: queryParams} }) {},
variable queryParams is an object:
{ user: "wonderman" }
I am using vue-head in website because of I have to pass the name of the program to the html head, and the inf. it is coming from an API, so I make the request but every time I try to pass the name it send me error this the code:
export default {
data: () => ({
errors: [],
programs: [],
firstVideo: {},
vidProgram: {}
}),
},
created() {
//do something after creating vue instance
this.api = new ApiCanal({})
this.getProgram()
},
methods: {
getProgram() {
this.api.http.get(`videos/program/${this.programSlug}`)
.then(response => {
this.programs = response.data
this.firstVideo = response.data[0]
this.vidProgram = response.data[0]['program']
})
.catch(error => {
this.errors = error
});
}
},
head: {
//this is the inf. for the head
title: {
inner: this.programs.name,
separator: '-',
complement: this.programs.info
}
}
}
I will really appreciate if you can help me with this issue
If you want to use properties of your Vue object/component in the title there, you need to make it a function, as currently this refers to the object creating your Vue component (probably the global window object).
head: {
title: function() {
return {
inner: this.programs.name,
separator: '-',
complement: this.programs.info
};
}
}
I am developing a Sencha Touch 2 app with user authentication.
I use a token for authentication.
The logic.
Check is a token exists in local storage:
var tokenStore = Ext.getStore('TokenStore'),
token = tokenStore.getAt(0).get('token');
If there is a token, check if it's valid.
I am doing a read from a model which is connected to my API which, returns success or fail - depending on the token - if it's valid or not.
TestApp.model.CheckAuthModel.load(1, {
scope: this,
success: function(record) {
// Here, I know the token is valid
},
failure: function() {
console.log('failure');
},
callback: function(record) {
console.log('callback');
console.log();
}
});
And here is the router, which handles the logic for the views:
Ext.define("TestApp.controller.Router", {
extend: "Ext.app.Controller",
config: {
refs: {
HomeView: 'HomeView',
LoginView: 'LoginView',
ProductsView: 'ProductsView',
ProductsViewTwo: 'ProductsViewTwo'
},
routes: {
'': 'home',
'home' : 'home',
'login' : 'login',
'products' : 'products',
'testingtwo' : 'testingtwo'
}
},
home: function () {
console.log('TestApp.controller.Router home function');
var initialItem = Ext.Viewport.getActiveItem(),
comp = this.getHomeView();
if (comp === undefined) comp = Ext.create('TestApp.view.HomeView');
Ext.Viewport.animateActiveItem(comp, {
type: 'slide',
listeners: {
animationend: function() {
initialItem.destroy();
}
}
});
},
login: function () {
var initialItem = Ext.Viewport.getActiveItem(),
comp = this.getLoginView();
if (comp === undefined) comp = Ext.create('TestApp.view.LoginView');
Ext.Viewport.animateActiveItem(comp, {
type: 'slide',
listeners: {
animationend: function() {
initialItem.destroy();
}
}
});
},
products: function () {
var initialItem = Ext.Viewport.getActiveItem(),
comp = this.getProductsView();
if (comp === undefined) comp = Ext.create('TestApp.view.ProductsView');
Ext.Viewport.animateActiveItem(comp, {
type: 'slide',
listeners: {
animationend: function(){
initialItem.destroy();
}
}
});
},
testingtwo: function () {
var initialItem = Ext.Viewport.getActiveItem(),
comp = this.getProductsViewTwo();
if (comp === undefined) comp = Ext.create('TestApp.view.ProductsViewTwo');
Ext.Viewport.animateActiveItem(comp, {
type: 'slide',
listeners: {
animationend: function(){
initialItem.destroy();
}
}
});
},
launch: function() {
console.log('TestApp.controller.Router launch!');
}
});
Now, how can I link the router with the check auth model callback?
I want to know the auth state when the app reaches the router.
In other MVC frameworks, I could do a before filter, on the router, check for auth and handle the routes accordingly.
Can i do this in Sencha Touch 2?
Any ideas?
Hi I think this section in the documentation is exactly what you need:
before : Object
Provides a mapping of Controller functions to filter functions that are run before them when dispatched to from a route. These are usually used to run pre-processing functions like authentication before a certain function is executed. They are only called when dispatching from a route. Example usage:
Ext.define('MyApp.controller.Products', {
config: {
before: {
editProduct: 'authenticate'
},
routes: {
'product/edit/:id': 'editProduct'
}
},
//this is not directly because our before filter is called first
editProduct: function() {
//... performs the product editing logic
},
//this is run before editProduct
authenticate: function(action) {
MyApp.authenticate({
success: function() {
action.resume();
},
failure: function() {
Ext.Msg.alert('Not Logged In', "You can't do that, you're not logged in");
}
});
}
});
http://docs.sencha.com/touch/2.3.1/#!/api/Ext.app.Controller-cfg-before
Of course, it's still up to you to decide whether you should check every time or should cache the auth result for sometime.
Updated to answer comment below
Honestly, i am not sure how they was going to declare that static method Authenticate in Sencha (you would be able to do it normally through Javascript i think, i.e.: prototype).
But there are other better options to solve just that Authenticate function:
Just create a singleton class that handle utility stuffs.
http://docs.sencha.com/touch/2.3.1/#!/api/Ext.Class-cfg-singleton
If you really want to use MyApp, you can declare within the Ext.app.Application (in app.js). Then call it from the global instance MyApp.app.some_function(). I wouldn't exactly recommend this method because you change app.js, that might bring problem if you upgrade sencha touch.
You could implemented auth check in application's launch function or in your auth controller's init function and based on the response redirect the to appropriate url. Something like this:
TestApp.model.CheckAuthModel.load(1, {
scope: this,
success: function(record) {
this.redirectTo("home/");
},
failure: function() {
this.redirectTo("login/");
console.log('failure');
},
callback: function(record) {
console.log('callback');
console.log();
}
});
