Laravel 表单数据未保存在 neo4j 图形数据库中
Laravel form data not saving in neo4j graph DB
我写了一个laravel form，截图如下：
我使用 neo4j 来存储该表单数据。
这是代码：
app/views/duck-form.blade.php
<!doctype html>
<html>
<head>
<title>Laravel Form Validation!</title>
<!-- load bootstrap -->
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

<div class="page-header">

</div>
@if ($errors->has())
<div class="alert alert-danger">
@foreach ($errors->all() as $error)
{{ $error }}<br>
@endforeach
</div>
@endif
<!-- FORM STARTS HERE -->
<form method="POST" action="/ducks" novalidate>
<div class="form-group @if ($errors->has('name')) has-error @endif">
<label for="name">Name</label>
<input type="text" id="name" class="form-control" name="name" placeholder="Enter your name" value="{{ Input::old('name') }}">
@if ($errors->has('name')) <p class="help-block">{{ $errors->first('name') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('email')) has-error @endif">
<label for="email">Email</label>
<input type="text" id="email" class="form-control" name="email" placeholder="Enter your email id" value="{{ Input::old('email') }}">
@if ($errors->has('email')) <p class="help-block">{{ $errors->first('email') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('password')) has-error @endif">
<label for="password">Password</label>
<input type="password" id="password" class="form-control" name="password">
@if ($errors->has('password')) <p class="help-block">{{ $errors->first('password') }}</p> @endif
</div>
<div class="form-group @if ($errors->has('password_confirm')) has-error @endif">
<label for="password_confirm">Confirm Password</label>
<input type="password" id="password_confirm" class="form-control" name="password_confirm">
@if ($errors->has('password_confirm')) <p class="help-block">{{ $errors->first('password_confirm') }}</p> @endif
</div>
<button type="submit" class="btn btn-success">Submit</button>
</form>

1。我将 'Artdarek\Neo4j\Neo4jServiceProvider' 添加到 app/config/app.php 中的提供程序数组。
2.我在app/config/database.php
中添加了neo4j配置
'neo4j' => [
'default' => [
'host' => 'localhost',
'port' => 7474,
'username' => null,
'password' => null,
],
],
3。然后我为该表单添加了一个控制器：
<?php
class DuckController extends BaseController {
public function showWelcome()
{
return View::make('duck');
}
}
4。这是我的routes.php。
<?php
Route::get('/', function()
{
return View::make('hello');
});
// route to show the duck form
Route::get('ducks', function()
{
return View::make('duck-form');
});
// route to process the ducks form
Route::post('ducks', array('before' => 'csrf', function()
{
// create the validation rules ------------------------
$rules = array(
'name' => 'required', // just a normal required validation
'email' => 'required|email|unique:ducks', // required and must be unique in the ducks table
'password' => 'required',
'password_confirm' => 'required|same:password' // required and has to match the password field
);
// create custom validation messages ------------------
$messages = array(
'required' => 'The :attribute is really really really important.',
'same' => 'The :others must match.'
);
// do the validation ----------------------------------
// validate against the inputs from our form
$validator = Validator::make(Input::all(), $rules, $messages);
// check if the validator failed -----------------------
if ($validator->fails()) {
// redirect our user back with error messages
$messages = $validator->messages();
// also redirect them back with old inputs so they dont have to fill out the form again
// but we wont redirect them with the password they entered
return Redirect::to('ducks')
->withErrors($validator)
->withInput(Input::except('password', 'password_confirm'));
} else {
// validation successful ---------------------------
// our duck has passed all tests!
// let him enter the database
// create the data for our duck
$duck = new Duck;
$duck->name = Input::get('name');
$duck->email = Input::get('email');
$duck->password = Hash::make(Input::get('password'));
// save our duck
$duck->save();
// redirect ----------------------------------------
// redirect our user back to the form so they can do it all over again
return Redirect::to('ducks')
->with('messages', 'Hooray!');
}
}));
5。这是 form 的模型文件：
<?php
class Duck extends Eloquent {
protected $fillable = array('name', 'email', 'password');
}
6.这是我 neo4j 的模型：
<?php
//use Illuminate\Auth\EloquentUserProvider;
class database extends Eloquent {
public function index($name, $email, $password, $password_confirm) {
$formData = Neo4j::makeNode();
$formData->setProperty('name',$name)
->setProperty('email',$email)
->setProperty('password',$password)
->setProprty('password_confirm',$password_confirm)
->save();
}
}
当我点击那个表单中的 submit 按钮时，我得到了这个错误：
[ Edit ]
我正在研究它：
这是我得到的新错误：
是 csrf 令牌问题吗？
它指向：
Route::filter('csrf', function()
{
if (Session::token() != Input::get('_token'))
{
throw new Illuminate\Session\TokenMismatchException;
}
});
5 小时后我无法解决它，并且数据未存储在 neo4j 数据库中。我该如何解决？
您的代码看起来不错，您可能需要 运行
composer dump-autoload
使用 CSRF Protection Filter 时，您的表单必须在 blade 中这样声明：
{{ Form::open(array('method' => 'POST', 'action' => URL::to("/ducks"))) }}
并关闭：
{{ Form::close() }}
这将在您的 html 中呈现与使用相同的表单：
<form method="POST" action="{{ URL::to("/ducks") }}">...</form>
但也会添加您缺少的隐藏 _token 元素：
<input type="hidden" name="_token" value="value_of_token"/>
希望对您有所帮助！

或者，如果您不想重新创建 <form>，您可以简单地使用：
{{ Form::token() }}
在现有 <form> 标签内的某处创建它。
