使用外键构建的架构

Question

我想知道是否有人可以告诉我如何SQL在Laravel 4Schema Builder中编写以下内容？

CREATE TABLE `conversation_reply` (
`cr_id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
`reply` text,
`user_id_fk` int(11) NOT NULL,
`ip` varchar(30) NOT NULL,
`time` int(11) NOT NULL,
`c_id_fk` int(11) NOT NULL,
FOREIGN KEY (user_id_fk) REFERENCES users(user_id),
FOREIGN KEY (c_id_fk) REFERENCES conversation(c_id)
);

Answer 1

如果我明白你在问什么,这应该是关闭的;

Schema::table('conversation_reply', function($table)
{
    $table->increments('cr_id');
    $table->text('reply')->nullable();
    $table->foreign('user_id_fk')->references('user_id')->on('users');
    $table->string('ip', 30);
    $table->integer('time');
    $table->foreign('c_id_fk')->references('c_id')->on('conversation');
});
