How to delete data using Vue js? - laravel

Question

I'm trying delete data but I'm getting this error:
this.jobPosts.filter is not a function
PostJobIndex.vue file:
deleteJobPost: async function(jobPost) {
if (!window.confirm('Are you sure you want to delete this Job Post?')) {
return;
}
try {
await employerService.deleteJobPost(jobPost.id);
this.jobPosts = this.jobPosts.filter(obj => {
return obj.id != jobPost.id;
});
console.log(this.jobPosts);
this.$toast.success("Job Post deleted Successfully!");
} catch (error) {
console.log(error);
this.$toast.error(error.response.data.message);
}
},
I had this same issue with my Update method and I beleive it was because I was trying to map through an object or something instead of an array. In the end I used Object.keys(this.jobPosts).map for my update method and it worked:
Object.keys(this.jobPosts).map(jobPost => {
if (jobPost.id == response.data.id) {
for (let key in response.data) {
jobPost[key] = response.data[key];
}
}
});
But when I do this for Update it doesn't work:
this.jobPosts = Object.keys(this.jobPosts).filter(obj => {
return obj.id != jobPost.id;
});
UPDATED
Here is the code for loading the job posts:
loadJobPosts: async function() {
try {
const response = await employerService.loadJobPosts();
this.jobPosts = response.data;
console.log(this.jobPosts);
} catch (error) {
this.$toast.error('Some error occurred, please refresh!');
}
},
Im using Vuex for state management and I'm using services, that simply contain the axios http requests. That's where this line comes from employerService.loadJobPosts() loadJobPosts() is a function inside my employerService.js file.
I'm also using Laravel for my back end. Here is my JobPostsController.php file:
public function index()
{
$jobPosts = JobPost::all()->where('user_id', Auth::user()->id);
return response()->json($jobPosts, 200);
}

From what I've understood from your code,
this should work for removing jobPost from jobPosts
this.jobPosts = this.jobPosts.filter(obj => {
return obj.id != jobPost.id;
});
I don't know what you're expecting this to do, but it won't do anything useful and will either error or return false for everything.
this.jobPosts = Object.keys(this.jobPosts).filter(obj => {
return obj.id != jobPost.id;
});
filter exists on array types, so I would check where it's getting set and make sure it's an array.
I've included a small snippet in case it's any help.
Vue.config.devtools = false;
Vue.config.productionTip = false;
new Vue({
el: "#app",
data: () => {
return {
jobPosts: [],
deleteJobId: 1
};
},
methods: {
getJobPosts() {
this.jobPosts = [{
id: 1
}, {
id: 2
}, {
id: 3
}, {
id: 4
}, {
id: 5
}];
},
deleteJob() {
if (!this.deleteJobId)
return;
this.jobPosts = this.jobPosts.filter(x => x.id !== this.deleteJobId);
}
}
});

<div id="app">

<div>
<button type="button" #click="deleteJob">Delete Job #</button>
<input type="number" v-model.number="deleteJobId" />
</div>
<ul>
<li v-for="jobPost in jobPosts">
Job Post #{{jobPost.id}}
</li>
</ul>

You have already answered your own question:
in my data() object, I have this jobPosts: [], but in the console it says Object
As for your second question:
I don't know how to return the data as an array
There are similiar topics here on SO.
I am not familiar with Laravel but assuming you have an eloquent model with JobPost in your index-function according to the docs you should use the .toArray-method:
$jobPosts = JobPost::all()->where('user_id', Auth::user()->id).toArray();
When working with plain collections the values method should do the trick of returning an array instead of an object:
$collection = collect([
10 => ['product' => 'Desk', 'price' => 200],
11 => ['product' => 'Desk', 'price' => 200]
]);
$values = $collection->values();
$values->all();
UPDATE
I just realized that your result is just a stringified JSON object that needs to be converted into an array. Just parse it before processing (take out the JSON.parse(...) if you are already taking care of it in your service), return the object properties as an array and you are good to go:)
this.jobPosts = Object.values(JSON.parse(this.jobPosts)).filter(obj => {
return obj.id != jobPost.id;
});
