Vue.js same form for add and edit - javascript

I'm a rookie on vue.js and I'm trying to extend some tutorials a completed.
Been fighting with this three hours now and I'm frustrated. FYI, I'm using firebase but I'm not sure it really matters here.
So, I have a CRUD app for listing movies (I told you it was basic!).
There is a form at the top of the page where you can add movies, and a table below it, where the new registries are listed. This works well.
I added Edit and Delete buttons to each row on the table. The delete function works. But the Edit function is the problem.
I'd like to use v-if on the initial form, to trigger different methods (save, edit) and show different buttons (Add, Save, Cancel).
I'm not sure how to access the objects to do this, I tried a couple of things and the v-if says the object is not defined.
thank you for reading, please ask anything you need.

You should change the isEditing to true when the Edit button clicked, and you should define the data movie.
editMovie: function (movie){
...
this.movie = Vue.util.extend({}, movie); // deep clone to prevent modify the original object
this.isEditing = true;
},

As suggested in the comments (by Ben), I added the movie declaration to the initial data object. So now it looks like this:
data () {
return {
isEditing: false,
newMovie: {
title: '',
director: '',
url: 'http://',
edit: false
},
movie: {
edit: false
}
}
},
Now v-if works just fine, like this:
<div v-if="!movie.edit">
"is Editing" was no longer necessary so I removed it.

Table not showing the data from database in laravel vue component

For the past few days, I have been following a tutorial about VUE application from a really good youtuber. I was following each and every step as it was mentioned in the tutorial when suddenly I have come to an abrupt halt. This is because the data from my database is not showing up in the frontend. The database does show that I am storing the data properly, and there are no errors whatsoever.
The video where I got stuck on is: https://youtu.be/bUXhGw4aQtA
Here is the code for the index in my controller
public function index()
{
return User::latest()->paginate(10);

Please let me know if any other code is required for me to elaborate on the query that I have here. I have tried all options that I could think of and search and couldn't get it to work. Hopefully, another set of eyes can help me figure out the problem.
I expect a full table showing all the rows from my database, and the front-end shows nothing. (Note: I did check the network tab in the developer's options in Chrome and there was only a single xhr type and it showed status 200).
I suggest you go on youtube to search for laravel/vue tutorials, there are tons of good resources there that can help you.
For what you are trying to achieve, if you have mounted your component well and can see a dummy test in the component on your browser, then you are half way done.
Inside your mounted hook of your vue component, make an api call to your backend (laravel) to fetch users like so;
axios.get('/get_all_users').then((res)=>{
this.users = res.data
//do a console.log(res.data) to ensure you are getting the users collection
}).catch((err) => {
console.log(err)
});
Inside your data object, create an empty array that holds your users like so;
data(){
return{
users: []
}
}
Now, inside your web.php, create a GET route for this api call;
ROUTE::get('/get_all_users', 'UsersController#FetchUsers');
Note that your controller and method necessarily not be named as above, create a controller, and inside, write a method to fetch users and use them here asap;
Inside your controller, write your method;
public function FetchUsers(){
$users = User::latest()->get();
return response()->json($users, 200);
}
Also note that you will need to import your User model at the top of the controller file like so;
use App\User;
Also ensure before now that you have the User model created that relates to your users table;
By now you should see the arrays of users on your browser developer tool console if everything is fine.
Then in your template, iterate through the users data like so;
<tr v-for="user in users" :key="user.id">
<td>{{ user.id }} </td>
<td>{{ user.name }} </td>
<td>{{ user.email }} </td>
<td>{{ user.created_at }} </td>
</tr>
I will be glad to help in case you need further clarifications.
You need to return your data as json. You can use Laravel [Resource]
(https://laravel.com/docs/5.8/eloquent-resources)
Create user resource
php artisan make:resource User
User Controller
use App\Http\Resources\User as UserResource;
On your Method
$user = User::latest()->paginate(10);
return UserResource::collection($user)

VeeValidate 'required_if:' rule

Can someone point me to the right direction?
I need this simple required_if rule to work before I go further.

Meteor Ironrouter trying to pass data but saying collection is not defined

Using IronRouter, I have successfully rendered the page's template. I am trying to pass data from a collection to the unique page, but there is an error saying that the collection is not defined. Subscriptions aren't a problem since autopublish is installed.
I get the data from the form, store it, and then I want to display that data on the routed page.
So far, for the collection, I have:
import { Meteor } from 'meteor/meteor';
import { Template } from 'meteor/templating';
import { Works } from '../api/works.js';
import './work.js';
import './body.html';
Template.main.helpers({
works() {
return Works.find({}, { sort: { createdAt: -1 } });
},
});
Template.main.events({
'submit .new-work'(event) {
event.preventDefault();
const title = event.target.title.value;
const workBriefDesc = event.target.workBriefDesc.value;
const workFullDesc = event.target.workFullDesc.value;
const workId = this._id;
Works.insert({
title,
workBriefDesc,
workFullDesc,
createdAt: new Date(),
owner: Meteor.userId(),
username: Meteor.user().username,
workId,
});
event.target.title.value = '';
event.target.workbriefdesc.value = '';
event.target.workfulldesc.value = '';
},
});
Template.collab.helpers({
works: function(){
return Works.findOne({_id:Router.current().params.workId});
},
});
And for the IronRouter file:
Router.route('/works/:_id', function () {
this.render('Collab');
}, {
name: 'collab',
data: function(){
return Works.findOne({ _id: this.params._id});
},
});
And the template file:
<!-- Publishing the template work -->
<template name="main">
<form class="new-work col s12">
<div class="row">

This is the error from the browser console:

Default option in select is not working using AngularJS

I am following an AngularJS tutorial, and I wanted to validate my form. I decided to add a default option to the select element.
However, even after adding selected="", the browser won't show it as default.
I have tried this without AngularJS and it works fine, so I'm guessing the script is blocking something.
How can I define a default option for my select element?
PS: I'm using Google Chrome Version 44.0.2403.157 m

From the dev guide for ngSelected;
The HTML specification does not require browsers to preserve the
values of boolean attributes such as selected. (Their presence means
true and their absence means false.) If we put an Angular
interpolation expression into such an attribute then the binding
information would be lost when the browser removes the attribute. The
ngSelected directive solves this problem for the selected attribute.
This complementary directive is not removed by the browser and so
provides a permanent reliable place to store the binding information.
In your controller add another property and reference it from there:
{
action: 'Call family',
complete: false,
selected: 'selected'
}];
{
action: 'Call family',
complete: false,
selected: ''
}];

What is the right approach to reload the model for a non-dynamic route with ember.js?

I'm having a simple array of models which I display in a list (path: /things). The models get loaded from a REST-API.
In a nested route I have the functionality to add a new model. (path: /things/add). The new model is persisted over a REST-API.
After adding the new model, I do a transitionTo('things') to get back to the list.
Following the ember documentation, by using "transitionTo" neither the model hook nor the setupController-Hook are called for non dynamic routes.
What is the right approach to refresh the model on a non-dynamic route, when using transitionTo? Or: what is the best way to reload a model on a non-dynamic route without using transitionTo?

So if you were using ember-data, a side effect of saving the record would be that the results of findAll() get updated. You can accomplish the same by either manually updating the array or triggering a refresh when a new record is added. In either case, suggest doing that from ThingsAddController's add fx. For example:
App.ThingsAddController = Em.ObjectController.extend({
needs: [things],
add : function() {
newThing = App.Thing.save(this.content);
this.get('controllers.things').pushObject(newThing);
this.transitionToRoute('things');
},
});
