Laravel - 在编辑视图上添加日期验证

Question

我有两张桌子——“旅行”和“活动”。一次旅行可以有很多事件。我有一个表单，允许用户将事件添加到他们的旅行中。我还有一个允许用户编辑事件的表单。

我在添加和事件时添加了一个检查。只有当活动的开始日期和结束日期在行程开始日期和行程结束日期之间时，才能添加该活动。

但是，我似乎无法在编辑视图上进行相同的检查。使用与我在编辑中添加的代码相同的代码，如果用户更改了活动的时间但未更改活动的开始/结束时间，则会出现日期错误消息 - 即使日期在行程内。

EventController - 添加正在运行的功能

public function addEvent(Request $request)
{
  $this->validate($request, [
    'event_name'  => 'required',
    'start_date'  => 'required',
    'end_date'    => 'required',
    'time'        => 'required',
    'trip_id'     => 'required',

  ]);

    $start_date = Carbon::parse($request['start_date'])->format('Y-m-d');
    $end_date = Carbon::parse($request['end_date'])->format('Y-m-d');

    $tripCheck = Trip::where('id', $request['trip_id'])
    ->whereDate('startdate', '<=', $start_date)
    ->whereDate('enddate', '>=', $start_date)

    ->whereDate('startdate', '<=', $end_date)
    ->whereDate('enddate', '>=', $end_date)
    ->first();

    if ($tripCheck) {

      $events = new Events;
      $trips = Trip::all();
      $categories = Categories::pluck('category','id');
      $events->category_id = $request['category_id'];
      $events->colour =  $request['colour'];
      $events->event_name = $request['event_name'];
      $events->start_date = $request['start_date'];
      $events->end_date = $request['end_date'];
      $events->time = $request['time'];
      $events->address = $request['address'];
      $events->notes = $request['notes'];
      $events->trip_id = $request['trip_id'];
      $events->save();

return redirect('trips')->with('success', 'The new event has been added to your trip')->with('trips', $trips)->withCategories($categories);
} else
  {
  return redirect('trips')->withErrors(['The dates you added are not within Trip start and end date.']);
   }

}

事件控制器编辑功能不起作用

public function edit($id)
{
  $events = Events::find($id);
  $categories = Categories::pluck('category','id');
  return view ('editEventForm')->with('events', $events)->withCategories($categories);
}

public function update(Request $request, $id)
{
    $this->validate($request, [
      'category_id' => 'required',
      'event_name' => 'required',
      'start_date' => 'required',
      'end_date' => 'required',
    ]);

    $start_date = Carbon::parse($request['start_date'])->format('Y-m-d');
    $end_date = Carbon::parse($request['end_date'])->format('Y-m-d');

    $tripCheck = Trip::where('id', $request['trip_id'])
    ->whereDate('startdate', '<=', $start_date)
    ->whereDate('enddate', '>=', $start_date)

    ->whereDate('startdate', '<=', $end_date)
    ->whereDate('enddate', '>=', $end_date)
    ->first();

    if($tripCheck) {

    //Update Event
    $events = Events::find($id);
    $events->category_id = $request['category_id'];
    $events->colour =  $request['colour'];
    $events->event_name = $request['event_name'];
    $events->start_date = $request['start_date'];
    $events->end_date = $request['end_date'];
    $events->time = $request['time'];
    $events->address = $request['address'];
    $events->notes = $request['notes'];
    $events->save();

    return redirect('trips')->with('success', 'Event Updated');
} else {
    return redirect('trips')->withErrors(['The dates you added are not within Trip start and end date.']);
}

}

trip.blade.php

<div class="form-group">
      <input type="text" name="destination" class="form-control" value="{{$trip->destination}}" placeholder="Destination" />
    </div>
    <h7>Trip Start Date: </h7>
    <div class="form-group">
      <input type="date" name="startdate" class="form-control" value="{{$trip->startdate}}" placeholder="Start Date" />
    </div>
    <h7>Trip End Date: </h7>
    <div class="form-group">
      <input type="date" name="enddate" class="form-control" value="{{$trip->enddate}}" placeholder="End Date" />
    </div>
    <div>

行程控制器

public function submit(Request $request){
  $this->validate($request, [
    'name'          => 'required',
    'email'         => 'required',
    'destination'   => 'required',
    'startdate'     => 'required',
    'enddate'       => 'required'
  ]);

  //Create new trips
  $trip = new Trip;
  $trip->name = $request->input('name');
  $trip->email = $request->input('email');
  $trip->destination = $request->input('destination');
  $trip->startdate = $request->input('startdate');
  $trip->enddate = $request->input('enddate');
  $trip->user_id = auth()->user()->id;

  //save trips
  $trip->save();

  //Rredirect
  return redirect('/home')->with('status', 'Trip Created Sucessfully');

}

Answer 1

update 方法正在寻找$request['trip_id']，它存在吗？它不像 create 方法那样在所需的验证中。

在您的更新表单中吗？

还有一个额外的提示，您可以通过在模型对象上使用 create 和 fill 来简化很多代码。

即：$trip = Trip::create($request->input()); 假设输入名称与模型匹配并且输入是干净的。
