Answer 1

对于第二个实例，请使用Schema::table

有关详细信息，请参阅此处：https://stackoverflow.com/a/28007930/938664

public function up()
    {
        Schema::create('user', function(Blueprint $table)
        {
            $table->engine = 'InnoDB';
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password', 60);
            $table->rememberToken();
            $table->timestamps();
            $table->integer('projectId')->unsigned();
            $table->boolean('isStudent');
            $table->boolean('isCompany');
            $table->string('img');

            $table->foreign('projectId')->references('id')->on('project')->onDelete('cascade');

        });


    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('user');
    }
}

Answer 2

尝试此Schema :: table

public function up()
{
    Schema::create('user', function(Blueprint $table)
    {
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->string('password', 60);
        $table->rememberToken();
        $table->timestamps();
        $table->integer('projectId')->unsigned();
        $table->boolean('isStudent');
        $table->boolean('isCompany');
        $table->String('img');
    });

    Schema::table('user', function($table)
    {
        $table->foreign('projectId')->references('id')->on('project');

    });


}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::drop('user');
} }
