Question

我试图将用户添加为租户。我使用朋友系统教程实现了它，它工作正常，直到我尝试修改它。我想在发送租赁请求时添加属性地址。我得到的错误是没有默认值。

SQLSTATE [HY000]：常规错误：1364字段＆＃39; property_address＆＃39;没有默认值（SQL：插入tenancies（tenancy_id，user_id）值（，4））

模型中的所有方法

//The users tenancies
    public function tenanciesOfMine(){
      return $this->belongsToMany('App\User', 'tenancies', 'user_id', 'tenancy_id', 'property_address');
    }

    //Inverse of user tenncies -> Both users have tenancy if one exists. One user can't be in a tenancy with someone who is not in tenacy with them.
    //Like friends on FB. You can't be friends with someone, without them being friends with you also.
    public function tenancyOf(){
      return $this->belongsToMany('App\User', 'tenancies', 'tenancy_id', 'user_id', 'property_address');
    }

    //If a tenancy is accepted, create the tenancy ie friendship.
    public function tenancies(){
      return $this->tenanciesOfMine()
        ->wherePivot('accepted', '=', true)
        ->wherePivot('property_address', '=', '1')->get()
          ->merge($this->tenancyOf()
            ->wherePivot('accepted', '=', true)
            ->wherePivot('property_address', '=', '1')->get());
    }

    //Request hasn't yet been accepted. Display list  of pending requests
    public function tenacyRequests(){
      return $this->tenanciesOfMine()->wherePivot('accepted', false)->get();
    }

    //Inverse of Tenancy Requests
    public function tenancyRequestsPending(){
      return $this->tenancyOf()->where('accepted', false)->get();
    }

    //If a user has a request pending from another user
    public function hasTenancyRequestsPending(User $user){
      return (bool) $this->tenancyRequestsPending()->where('id', $user->id)->count();
    }

    public function hasTenancyRequestsReceived(User $user){
      return (bool) $this->tenacyRequests()->where('id', $user->id)->count();
    }

    //Add tenancy
    public function addTenancy(User $user){
      $this->tenancyOf()->attach($user->id);
    }

    //Add tenancy
    public function acceptTenancyRequest(User $user){
      $this->tenacyRequests()->where('id', $user->id)->first()->pivot->update([
        'accepted' => true,
      ]);
    }
    public function isInTenancyWith(User $user){
      return $this->tenancies()->where('id', $user->id)->count();
    }

这是添加方法

public function getAdd($id){
    $user = User::where('id', $id)->first();

    if(!$user){
      return redirect('/')->with(['status', 'Profile Not Found']);
    }

    if(Auth::user()->id === $user->id){
        return redirect()->route('home');
    }

    if (Auth::user()->hasTenancyRequestsPending($user) ||
        $user->hasTenancyRequestsPending(Auth::user())){
          return redirect('/account/{{$user->id}}')->with('status', "Friend request already pending");
      }

    if(Auth::user()->isInTenancyWith($user)){
      return redirect('/account/{{$user->id}}')->with('status', "Already i a tenancy");
    }

    //After passing all checks. Add other account
    Auth::user()->addTenancy($user);

    return redirect('/account/{{$user->id}}')->with('status', "Request Sent");
  }

这是创建表单。房东和租户已经由user_id和租赁ID表示。所以我只需要在其中使用property_Address。其他名称用于视觉效果

<form action="/account/{{$user->id}}/add" method="POST">
              {{ csrf_field() }}
              <div class="row">
                <div class="col-md-6">

纯粹是因为你得到的SQL错误，也许你需要确保property_address在你的数据库中可以为空？（即删除not null约束（如果有约束）。

字段没有默认值。添加＆＃34;朋友＆＃34;
