Question

所以，我一直在使用Phinx创建迁移。我希望能够在运行种子文件之前截断所有表（148个表）。我正在考虑创建一个将首先运行的种子文件，然后它将截断所有表。问题是如果我们添加更多表格，我不想更改此文件。我该怎么做呢也许做一个显示表然后循环它们，但不完全确定如何做到这一点。任何帮助都会很棒！这是我到目前为止所做的。

<?php
use Phinx\Seed\AbstractSeed;
class BonusRuleTypesSeeder extends AbstractSeed
{
    public function run()
    {
        $this->execute('SET foreign_key_checks=0');
        // some code here
        $this->execute('SET foreign_key_checks=1');
    }
}

Answer 1

如果您有迁移表，那么这也会截断该表。这样可行。

 $this->execute('SET foreign_key_checks=0');   
        foreach($tables as $table){
            $table = $table["Tables_in_".$database];
            if ($table != $config->getProperty(['phinx', 'default_migration_table'])){
                $sql = "TRUNCATE TABLE ".$table;
                $this->execute($sql);
            }
        }

Answer 2

以下是答案

$config = new Config(__DIR__.'/../../config/default.ini',true);
        $host = $config->getProperty(['db', 'host']);
        $database = $config->getProperty(['db', 'name']);
        $username = $config->getProperty(['db', 'username']);
        $password = $config->getProperty(['db', 'password']);

        $mysqli = new mysqli($host, $username, $password, $database);
        $query = "Show tables";
        $tables = $mysqli->query($query);
        $tables->fetch_all();
        $mysqli->close();

        $this->execute('SET foreign_key_checks=0');   
        foreach($tables as $table){
            $table = $table["Tables_in_".$database];
            $sql = "TRUNCATE TABLE ".$table;
            $this->execute($sql);
        }
        $this->execute('SET foreign_key_checks=1');
