Not able to understand why computed doesn't work without watch - laravel

The following code of inertiajs with vue only works this way
computed: {
flash: function () {
if (this.$page.props.flash.message) {
this.$toast.open({
type: this.$page.props.flash.type,
message: this.$page.props.flash.message.message,
})
}
return this.$page.props.flash.message
}
},
watch: {
flash: function (newVal, oldVal) {
}
},
but if i remove the watch part, it doesn't work. Also if i put the toast part inside watch, it doesn't work. Anyone facing same issue? I am working with inertiajs on laravel 8.

Try this
computed: {
flash(){
if (this.$page.props.flash.message) {
this.$toast.open({
type: this.$page.props.flash.type,
message: this.$page.props.flash.message.message,
})
}
return this.$page.props.flash.message
}
},

Watch Value In Vue.js 3, Equivalent In Pinia?

I have a checkbox list of domain tlds, such as com, net, io, etc. I also have a search text input, where I can drill down the list of 500 or so domains to a smaller amount. For example, if I start to type co in to my search text input, I will get back results that match co, such as co, com, com.au, etc. I am using Laravel and Vue,js 3 to achieve this with a watcher. It works beautifully. How can an achieve the same within a Pinia store?
Here is my code currently:
watch: {
'filters.searchedTlds': function(after, before) {
this.fetchsearchedTlds();
}
},
This is inside my vue component.
Next is the code to fetch searched tlds:
fetchsearchedTlds() {
self = this;
axios.get('/fetch-checked-tlds', { params: { searchedTlds: self.filters.searchedTlds } })
.then(function (response) {
self.filters.tlds = response.data.tlds;
console.log(response.data.tlds);
})
.catch(function (error) {
console.log(error);
})
.then(function () {
// always executed
});
},
And finally, the code inside my Laravel controller:
public function fetchCheckedTlds(Request $request)
{
$data['tlds'] = Tld::where('tld', 'LIKE','%'.$request->input('searchedTlds').'%')->pluck('tld');
return response()->json($data);
}
I am converting my code to use a Pinia store and I am stuck on how to convert my vue component watcher to Pinia?
Many thanks in advance.
To watch a pinia status, you may watch a computed attribute based on pinia or use watch getter
Your pinia may look like the one below.
~/store/filters.js
export const useFilters = defineStore('filters', {
state: () => {
return {
_filters: {},
};
},
getters: {
filters: state => state._filters,
},
...
}
In where you want to watch
<script setup>
import { computed, watch } from 'vue';
import { useFilters } from '~/store/filters.js';
const filters = useFilters();
// watch a computed attributes instead
const searchedTlds = computed(() => {
return filters.filters?.searchedTlds || '';
});
watch(
searchedTlds,
(newValue, oldValue) {
fetchsearchedTlds();
}
);
// or use watch getter
watch(
() => {
return filters.filters?.searchedTlds || '';
},
(newValue, oldValue) {
fetchsearchedTlds();
}
);
</script>
The first parameter of watch() can be a single ref or a getter function, or an array of getter functions, for more details, please view the Watch Source Types.

Data not showing on vue.js component using laravel api

I'm trying to get the data from database using an API, but there are no output on my vue controller.
Am I doing this right?
I think I'm assigning the scheduleList the wrong way.
I'm very new to vue.js and API, I want to know what I'm doing wrong here.
Controller
public function schedules(){
return Schedule::all();
}
api.php
Route::get('schedules', 'CalendarController#schedules');
Vue Component
<script>
import axios from 'axios'
export default {
data() {
return {
schedules: [],
scheduleList: [
{
id: schedules.id,
title: schedules.title,
category: schedules.category,
start: schedules.start,
end: schedules.end
},
],
};
},
methods: {
loadSchedules() {
axios.get('/api/schedules')
.then((response) => {
this.schedules = response.data;
})
}
},
mounted() {
this.loadSchedules();
}
};
</script>
<style>
</style>
The issue is in your data option because you're referencing schedules which is undefined, I'm sure that you're meaning this.schedules but doing that will not solve the issue because at first rendering this.schedules is an empty array, another problem that you're referencing at as object in scheduleList items using schedules.id, if the schedules property is an array i recommend the following solution :
<script>
import axios from 'axios'
export default {
data() {
return {
schedules: [],
scheduleList: [],
};
},
methods: {
loadSchedules() {
axios.get('/api/schedules')
.then((response) => {
this.schedules = response.data;
let schedule=this.schedules[0]
this.scheduleList.push({
id: schedule.id,
title: schedule.title,
category: schedule.category,
start: schedule.start,
end: schedule.end
})
})
}
},
mounted() {
this.loadSchedules();
}
};
</script>
always catch errors if you do promises.
loadSchedules() {
axios.get('/api/schedules')
.then((response) => {
this.schedules = response.data;
})
.catch(error => {
console.log(error)
})
inside your error you can better see whats going wrong.
other way is the "network" tab in your browser where you can trace your api request

Prevent Vuetify from printing to console "[Vuetify] Image load failed"

I am using Vuetify to load an image:
<v-img :src="this.imageUrl" :lazy-src="defaultImage" v-on:error="onError" :width="100" :height="150"></v-img>
data () {
return {
defaultImage: require('#/assets/images/defaultImage.png'),
useFallbackImage: false
}
},
computed: {
imageUrl: function() {
return !this.useFallbackImage ? `http://foo/v1.0/bar/${this.propId}` : this.defaultImage;
}
},
methods: {
onError: function() {
this.useFallbackImage = true;
}
}
I don't know if the image exists, so I am letting the browser try, and if it doesn't then fallback to the default. This works just fine, but Vuetify annoyingly prints a bunch of junk to the console:
"[Vuetify] Image load failed ... found in ..."
I looked in the source code and it looks like they are indiscriminately printing to the console whenever an error even before the handler. But I thought I would try -- does anybody know of a way to squelch Vuetify here?
Thanks
You maybe able to do something like this:
import VImg from 'vuetify/lib/components/VImg'
export default VImg.extend({
name: 'VImageWrapper',
methods: {
onError() {
// leave empty
}
}
})

How to get data by axios call in a mounted component?

I'm working on getting data from API by performing api call with axios. But my attempts to get data from api aren't succesful. How to make it work?
export default {
mounted() {
this.fetchData()
},
data() {
return {
users:[]
}
},
methods: {
fetchData(){
axios.get('api/person')
.then(response => (this.users= response.data))
.catch(error => console.log(error));
}
},
}
In ExampleComponent have these lines
<template>
...
<div>{{users.name}}</div>
<div>{{users.ip}}</div>
...
</template>
In api.php
Route::get('/person', function() {
$users = DB::table('user_info')->select('ip','name')->get();
return $users;
});
Running php artisan tinker I did
DB::table('user_info')->select('ip','name')->get();
I've got all my data from DB(users with names and IP's).
In the dev console, I see my data in response tab. But it is nothing in my page.
you need v-for:
<div v-for="user in users">
<div>{{user.name}}</div>
<div>{{user.ip}}</div>
</div>
so for every users you will show info.
There is a problem in vue : it should be {users.ip} and {users.name} in template.
that is how i get my data.
<script>
export default {
data() {
return {
properties: []
}
},
methods: {
loadproperty(){
axios.get('allhouses').then(response => this.properties = response.data);
},
},
mounted() {
this.loadproperty();
}
}
</script>

How to write test cases for titanium with alloy

I am stuck while writing test cases for alloy framework as i am not getting how to use controllers and alloy files in mocha testing framework. I searched on google and few links suggested below code to moke a controller but it throws error that "TypeError: alloy.createController is not a function".
var alloy = require('../../alloy');
it('Verify row controller', function() {
console.log(JSON.stringify(alloy))
var controller = alloy.createController('login', {
name : "uniqueName",
});
// if(controller.passwordTest.value !== "uniqueName"){
// throw new ("Verify row controller FAILED");
// }
});
Currently, I can show you a (slightly modified) example of our codebase.
First of all, our controller tests are pure javascript tests. All calls to the Ti api are executed against a mock. We solely focus on the controller under test and all dependencies are mocked.
We rely on jasmine and jasmine-npm for that.
install jasmine-npm; see https://github.com/jasmine/jasmine-npm
create 'spec' folder in the root of your project (folder with tiapp.xml)
place all your test files inside this folder
the filenames of test files must end with _spec.js
run the jasmine command from within the root folder of your project
describe('authenticate controller test', function() {
var USER_NAME = "John Doe";
var fooControllerMock = {
getView: function(){}
};
var fooViewMock = {
open: function(){}
}
Ti = {
// create here a mock for all Ti* functions and properties you invoke in your controller
}
Alloy = {
CFG: {
timeout: 100
},
Globals: {
loading: {
hide: function(){}
},
networkClient: {
hasAutoLogin: function(){}
},
notifications: {
showError: function(){}
}
},
createController: function(){}
};
var controllerUnderTest; // class under test
$ = {
btnAuthenticate: {
addEventListener: function(){}
},
authenticate: {
addEventListener: function(){},
close: function(){}
},
username: {
addEventListener: function(){},
getValue: function(){}
},
password: {
addEventListener: function(){}
},
windowContainer: {
addEventListener: function(){}
}
};
L = function(s){
return s;
};
beforeEach(function () {
controllerUnderTest = require('../app/controllers/auth');
});
it('should create foo controller when authentication was succesful', function(){
spyOn(Alloy.Globals.loading, 'hide');
spyOn(Alloy, 'createController').and.returnValue(fooControllerMock);
spyOn(fooControllerMock, 'getView').and.returnValue(fooViewMock);
spyOn($.username, 'getValue').and.returnValue(USER_NAME);
spyOn($.auth, 'close');
controllerUnderTest.test._onAuthSuccess();
expect(Alloy.Globals.loading.hide).toHaveBeenCalled();
expect(Alloy.createController).toHaveBeenCalledWith('foo');
expect(fooControllerMock.getView).toHaveBeenCalled();
expect($.auth.close).toHaveBeenCalled();
});
it('should show error message when a login error has occured', function(){
spyOn(Alloy.Globals.loading, 'hide');
spyOn(Alloy.Globals.notifications, 'showError');
controllerUnderTest.test._onAuthLoginError();
expect(Alloy.Globals.loading.hide).toHaveBeenCalled();
expect(Alloy.Globals.notifications.showError).toHaveBeenCalledWith('msg.auth.failure');
});
});
Be sure to write a mock implementation(just empty) for all Ti* stuff you call from within your controller. I know this is quite cumbersome but a solution is on it's way.
Note that we already created an npm package which has a generated mock for this (based on api.jsca), together with some code with which you can mock all required dependencies, together with a set of testing best practices. However we will validate this code internally before we opensource it. I hope we can write our blog post and expose our accompanying github repo within a few weeks. Just keep an eye on tiSlack.
Controller code:
function _onAuthSuccess() {
Alloy.Globals.loading.hide();
Alloy.createController('foo').getView().open();
$.authenticate.close();
}
function _onAuthLoginError() {
Alloy.Globals.loading.hide();
Alloy.Globals.notifications.showError(L('msg.auth.failure'));
}
function _onAuthTokenValidationFailure() {
Alloy.Globals.loading.hide();
}
function _authenticate() {
var username = $.username.value;
var password = $.password.value;
if(Alloy.Globals.validationEmail.isValidEmailAddress(username)){
Alloy.Globals.loading.show(L('authenticate.msg.logging.in'), false);
} else {
Alloy.Globals.notifications.showError(L('app.error.invalid.email'));
}
}
function _onNetworkAbsent() {
Alloy.Globals.loading.hide();
Alloy.Globals.notifications.showError(L('global.no.network.connection.available'));
}
function _hideKeyboard() {
$.username.blur();
$.password.blur();
}
function _focusPassword() {
$.username.blur();
$.password.focus();
}
function _init() {
Ti.App.addEventListener('auth:success', _onAuthSuccess);
Ti.App.addEventListener('auth:loginFailed', _onAuthLoginError);
Ti.App.addEventListener('app:parseError', _onAppParseError);
Ti.App.addEventListener('network:none', _onNetworkAbsent);
$.btnAuthenticate.addEventListener('click', ..);
$.authenticate.addEventListener('close', _cleanup);
$.username.addEventListener('return', _focusPassword);
$.password.addEventListener('return', _authenticate);
$.windowContainer.addEventListener('touchstart', _hideKeyboard);
}
_init();
function _cleanup() {
Ti.API.info('Closing and destroying the auth controller');
...
$.windowContainer.removeEventListener('touchstart', _hideKeyboard);
$.destroy();
$.off();
}
module.exports = {
test: {
_onAuthSuccess: _onAuthSuccess,
_onAuthLoginError: _onAuthLoginError
}
}
and the corresponding view:
<Alloy>
<Window>
<View id="windowContainer">
<TextField id="username" />
<TextField id="password" >
<Button id="btnAuthenticate" />
</View>
</Window>
</Alloy>
Titanium internally uses Ti-Mocha to write unit-tests for all of it's components. It's a modified version of Mocha and uses test-suites, test-cases, chaining and much more to test suitable code-coverage. Give it a try!
