Thinkphp5 uses the seeder in composer

Cause:

A few days ago, the customer asked to build a member question and answer system, so I followed the process. When it came time to call the database data, I felt that a It’s a bit stupid to add this~

Solution process:

After checking the manual and looking at foreign blog cases, I came up with a good method~~~

My usage record has been screenshot:

php think seed:create UserSeeder

UserSeeder file. After the creation is successful, you can database/seeds See below the directory:

database|-seeds
|-|-UserSeeder.php

<?phpuse think\migration\Seeder;class UserSeeder extends Seeder
{    /**
     * Run Method.
     *
     * Write your database seeder using this method.
     *
     * More information on writing seeders is available here:
     * http://docs.phinx.org/en/latest/seeding.html
     */    public function run()
    {

    }
}

run is given by default Method, now we all know that the seeder file is used to generate simulation data, and the code to generate simulation data can be written in the run method.

run method, we can fill in any code that can fill the database. Here I will give you some ideas:

Requirements: Give the data table
Users to simulate and generate 100 pieces of data. The table structure is as follows:

<?phpuse think\migration\Seeder;class UserSeeder extends Seeder
{    /**
     * Run Method.
     *
     * Write your database seeder using this method.
     *
     * More information on writing seeders is available here:
     * http://docs.phinx.org/en/latest/seeding.html
     */    public function run()
    {
        $rows = [];        for ($i = 0; $i < 100; $i++) {
            $rows[] = [                &#39;nickname&#39; => mt_rand(10000, 99999),                &#39;email&#39; => mt_rand(10000, 99999).&#39;@qq.com&#39;,                &#39;password&#39; => md5(&#39;123456&#39;),
            ];
        }        $this->table(&#39;users&#39;)->insert($rows)->save();
    }
}

save()

method, otherwise it will not be saved.

First, I generated 100 pieces of data, and then called

Insert the generated data into the Users table of the database. Is not it simple? ^ - ^.Execute Seeder

After the Seeder file is defined, the data must be executed before it can be inserted into the database. We can execute it like this:

php think seed:run

Execute Success tip:

. You can see:

##php think seed:run
