Question

我在此下方创建了form team.blade.php

组队index.blade.php

与该用户一起显示一个团队用户的名称，并显示该用户正在完成的项目，并将该用户显示为什么（角色）。

一个用户的关系有很多团队。一个团队有很多用户。因此，我选择多对多关系。但是在创建团队时，我想在数据透视表user_teams表中插入user_id和team_id作为用户与团队之间的关系表。

但是当我尝试创建团队失败时，他没有将数据保存到user_teams表中。并且在团队索引中，他没有与该用户一起显示团队用户的名称，而是显示该用户正在执行的项目，并将该用户显示为what。

我的用户模型

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use App\Presence;
use App\Models\Project;
use App\Productivity;
use App\Sick_leave;
use App\Annual_leave;
use App\Models\Team;

class User extends Authenticatable
{
use Notifiable;

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'name', 'email', 'password', 'role_id',
];

/**
 * The attributes that should be hidden for arrays.
 *
 * @var array
 */
protected $hidden = [
    'password', 'remember_token',
];

public function role()
    {
        return $this->belongsTo(Role::class, 'role_id');
    }

public function teams()
    {
        return $this->belongsToMany(Team::class, 'user_teams');
    }

public function projects()
    {
        return $this->belongsToMany(Project::Class, 'user_projects');
    }
    }

团队模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use App\User;
use App\Role;
use Auth;

class Team extends Model
{
use SoftDeletes;

protected $table = 'teams';
protected $fillable = [
    'id', 
    'project_id',  
];

public function users()
{
    return $this->belongsToMany(User::class, 'user_teams');
}

public function project()
{
    return $this->belongsTo(Project::class);
}

public function role()
{
    return $this->belongsTo(Role::class);
}

}

项目模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Project extends Model
{
use SoftDeletes;
protected $table = 'projects';
protected $fillable = [
    'project_id',
    'project_name',
    'start_date',
    'end_date',
    'project_category',
];

public function users()
{
    return $this->belongsToMany(User::class, 'user_projects');
}

public function team()
{
    return $this->hasOne(Team::class);
}
}

UserTeam模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class UserTeam extends Model
{
use SoftDeletes;    
protected $table = "user_teams";

public function team()
{
    return $this->belongsTo(Team::class);
}

public function user()
{
    return $this->belongsTo(User::class);
}
}

团队负责人

public function index()
{
    $users = auth()->user()->name;
    $users = User::all();
    return view ('teams.index', compact ('teams', 'users', 'projects'));
}
public function create()
{
    $users = User::all();
    $projects = Project::pluck('project_name', 'id');
    return view ('teams.form', compact('projects', 'users'));
}
public function store(Request $request)
{
    $team = Team::create($request->all());
    $userIds = User::find(2);
    $team->users()->attach($userIds);
    return redirect()->route('team.create');
}

在user_teams中具有字段user_id和team_id。我该如何克服呢？

Answer 1

您必须创建团队，然后附加属于该团队的用户。

docs中的示例：

附加

Eloquent还提供了一些其他的帮助方法来使工作正常进行与相关型号比较方便。例如，假设一个用户可以有很多角色，一个角色可以有很多用户。附加角色通过在连接的中间表中插入一条记录向用户显示模型，请使用attach方法：

$user = App\User::find(1);

$user->roles()->attach($roleId);

您的情况：

团队负责人

public function store(Request $request)
{
    $team = Team::create($request->except('user_id'));
    $team->users()->attach($request->get('user_id', []));
    return redirect()->route('team.create');
}
