Laravel中的CRUD错误
[英]CRUD error in Laravel
问题描述
Hello guys I made a CRUD(just create and read ) in Laravel project ,the create is working good and i passed the "loan" in show function but in the view it says undefined variable: 
大家好，我在Laravel项目中创建了一个CRUD（只需创建并读取），创建工作正常，我在show函数中传递了“贷款”，但在视图中它显示了未定义的变量：
my show function in controller: 我在控制器中的显示功能：
public function show($id)
{
$loan=loan::find($id);
return view('finance/loans')->with('loan',$loan);
}
My routes: 我的路线：
Auth::routes();
Route::get('/loans', 'LoanController@viewLoanForm');
Route::post('/loans', 'LoanController@store');
Route::get('/home', 'HomeController@index')->name('home');
Route::resource('loan','loanController');
Route::get('finance/loans', function () {
return view('loans');
});
And here is where i call the variable loan in the view: 这是我在视图中称为可变贷款的地方：
@extends('layouts.app')
@section('content')
<link href="{{ asset('css/loans.css') }}" rel="stylesheet">
<html>
<div class="container">
...
</div>
</div>
</div>
<div class="row">
<h1>{{$loan->nume}}</h1>//"nume"is the row from db i want to show
</div>
</div>
</html>
@endsection

You misspelled the route! 您拼错了路线！ Your request does not reach the controller method 您的请求未达到控制器方法
Route::get('finance/loans', function () {
return view('loans');
});
should be so 应该是这样
Route::get('finance/loans/{$id}','loanController@show');
or should use the controller resource route 或应使用控制器资源路由
Route::resource('loans','loanController');
url 'loans/show/{$loan_id}' 网址“贷款/显示/ {$ loan_id}”
<a href="route('loans.show',[$id])">Show Loan</a>

your return should be like this: 您的回报应该是这样的：
return view('finance/loans')->with(['loan'=>$loan]);
instead of 代替
return view('finance/loans')->with('loan',$loan);

用这个 ：
return view('finance.loans',compact(['loan']));

I think you need to on the route::resource('finance/loans') instead of ('loans'). 我认为您需要使用route :: resource（'finance / loans'）而不是（'loans'）。 And will work for sure 并且肯定会工作
