我正在使用laravel,我试图检查用户是否关注用户,如果是,则文本框将从关注变为关注。
我可以轻松获得用户的ID,但是我无法检查用户是否具有可追踪的ID
我需要引用数据透视对象,并且该对象仅在我执行操作时显示
<div id="profile" data='{{ $myuser->followers}}'></div>
但是我需要自己使用$myuser
变量。
这是我到目前为止所拥有的。
Profile.blade.php
<div id="profile" data='{{ $myuser}}'></div>
Profile.js
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import axios from 'axios';
export default class Example extends Component {
constructor(props){
super(props);
let id = JSON.parse(this.props.data);
// console.log('data from component', JSON.parse(this.props.data));
this.state = {
btnText: 'Follow',
className: 'follow-button',
user:{
// i can get a user id, but i cant get the followable id.
id:id.id,
followers:id.pivot.followable_id
}
};
}
myfollow(user) {
axios('/user/follow/'+ this.state.user.id , { method: "POST" })
.then(response => {
console.log(response);
});
};
componentDidMount(){
console.log('data from component', this.state.user.followers);
// if (this.state.user.followers === 3){
// this.setState({
// btnText:'Following',
// className:'following-button'
// });
// }
}
UserController.php
public function getProfile($user)
{
$users = User::with(['posts.likes' => function($query) {
$query->whereNull('deleted_at');
$query->where('user_id', auth()->user()->id);
}, 'follow','follow.follower'])
->where('name','=', $user)->get();
$user = $users->map(function(User $myuser){
$myuser['followedByMe'] = $myuser->follow->count() == 0 ? false : true;
return $myuser;
});

return redirect('404');
