README

Seed your database with CSV files

This package allows CSV based seeds.

Installation

Require this package in your composer.json and run composer update (or run composer require flynsarmy/csv-seeder:1.* directly):

"flynsarmy/csv-seeder": "1.0.*"

Usage

Your CSV's header row should match the DB columns you wish to import. IE to import id and name columns, your CSV should look like:

id,name
1,Foo
2,Bar

Seed classes must extend Flynsarmy\CsvSeeder\CsvSeeder, they must define the destination database table and CSV file path, and finally they must call parent::run() like so:

use Flynsarmy\CsvSeeder\CsvSeeder;

class StopsTableSeeder extends CsvSeeder {

    public function __construct()
    {
        $this->table = 'your_table';
        $this->filename = base_path().'/database/seeds/csvs/your_csv.csv';
    }

    public function run()
    {
        // Recommended when importing larger CSVs
        DB::disableQueryLog();

        // Uncomment the below to wipe the table clean before populating
        DB::table($this->table)->truncate();

        parent::run();
    }
}

Drop your CSV into /database/seeds/csvs/your_csv.csv or whatever path you specify in your constructor above.

Configuration

In addition to setting the database table and CSV filename, two other configuration options are available. They can be set in your class constructor:

  • insert_chunk_size (int 500) An SQL insert statement will trigger every insert_chunk_size number of rows while reading the CSV
  • csv_delimiter (string ,) The CSV field delimiter.
  • hashable (string password) Hash the hashable field, useful if you are importing users and need their passwords hashed. Uses Hash::make(). Note: This is EXTREMELY SLOW. If you have a lot of rows in your CSV your import will take quite a long time.
  • offset_rows (int 0) How many rows at the start of the CSV to ignore. Warning: If used, you probably want to set a mapping as your header row in the CSV will be skipped.
  • mapping (array []) Associative array of csvCol => dbCol. See examples section for details. If not specified, the first row (after offset) of the CSV will be used as the mapping.

Examples

CSV with pipe delimited values:

public function __construct()
{
    $this->table = 'users';
    $this->csv_delimiter = '|';
    $this->filename = base_path().'/database/seeds/csvs/your_csv.csv';
}

Specifying which CSV columns to import:

public function __construct()
{
    $this->table = 'users';
    $this->csv_delimiter = '|';
    $this->filename = base_path().'/database/seeds/csvs/your_csv.csv';
    $this->mapping = [
        0 => 'first_name',
        1 => 'last_name',
        5 => 'age',
    ];
}

Skipping the CSV header row (Note: A mapping is required if this is done):

public function __construct()
{
    $this->table = 'users';
    $this->csv_delimiter = '|';
    $this->filename = base_path().'/database/seeds/csvs/your_csv.csv';
    $this->offset_rows = 1;
    $this->mapping = [
        0 => 'first_name',
        1 => 'last_name',
        2 => 'password',
    ];
}
