1.数据库迁移：
1 php artisan make:model Message –m****_create_messages_table：
1 <?php 2 3 use IlluminateDatabaseMigrationsMigration; 4 use IlluminateDatabaseSchemaBlueprint; 5 use IlluminateSupportFacadesSchema; 6 7 class CreateMessagesTable extends Migration 8 { 9 /** 10 * Run the migrations. 11 * 12 * @return void 13 */ 14 public function up() 15 { 16 Schema::create('messages', function (Blueprint $table) { 17 $table->bigIncrements('id'); 18 $table->unsignedBigInteger('from_user_id')->comment("发送私信的用户的id"); 19 $table->unsignedBigInteger('to_user_id')->comment("接受私信的用户的id"); 20 $table->text('content')->comment("私信的内容"); 21 $table->timestamp('read_at')->nullable()->comment("接收方阅读的时间"); 22 $table->timestamps(); 23 }); 24 } 25 26 /** 27 * Reverse the migrations. 28 * 29 * @return void 30 */ 31 public function down() 32 { 33 Schema::dropIfExists('messages'); 34 } 35 } 36 37
2.模型关联：
Message.php
1 <?php 2 3 namespace App; 4 5 use IlluminateDatabaseEloquentModel; 6 7 class Message extends Model 8 { 9 // 10 11 protected $table = 'messages'; 12 13 protected $fillable = ['from_user_id', 'to_user_id', 'content']; 14 15 public function fromUser() 16 { 17 return $this->belongsTo(User::class, 'from_user_id'); 18 } 19 20 public function toUser() 21 { 22 return $this->belongsTo(User::class, 'to_user_id'); 23 } 24 } 25 26
