Laravel CSV Seeder

Seed your database using CSV files with Laravel

With this package you can save time for seeding your database. Instead of typing out the seeder files, you can use CSV files to fill up the database of your project. There are configuration options available to control the insert the data of your CSV files.

Features

  • Automatically try to resolve CSV filename to table name.
  • Automatic mapping of CSV headers to table column names.
  • Skip seeding data with a prefix at in the CSV headers.
  • Parse values with custom closure.
  • Hash values with a given array of column names.
  • Seed default values in to table columns.
  • Adjust Laravel's timestamp at seeding.

Installation

  • Require this package directly by

    composer require --dev jeroenzwart/laravel-csv-seeder

  • Or add this package in your composer.json and run composer update

    "jeroenzwart/laravel-csv-seeder": "1.*"

Basic usage

Extend your seed classes with JeroenZwart\CsvSeeder\CsvSeeder and set the variable $this->file with the path of the CSV file. Tablename is not required, if the filename of the CSV is the same as the tablename. At last call parent::run() to seed. A seed class will look like this;

use JeroenZwart\CsvSeeder\CsvSeeder;

class UsersTableSeeder extends CsvSeeder
{
    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
    }

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // Recommended when importing larger CSVs
        DB::disableQueryLog();
        parent::run();
    }
}

Place your CSV into the path /database/seeds/csvs/ of your Laravel project or whatever path you specify in the constructor. As default the given CSV require a header row with names, matching the columns names of the table in your database. Looks like this;

first_name,last_name,birthday
Foo,Bar,1970-01-01
John,Doe,1980-01-01

Configuration

  • tablename (string NULL) - Name of table to insert data.
  • connection (string NULL) - Name of database connection.
  • truncate (boolean TRUE) - Truncate the table before seeding.
  • header (boolean TRUE) - CSV has a header row, set FALSE if not.
  • mapping (array []) - Associative array of column names in order as CSV, if empty the first row of CSV will be used as header.
  • aliases (array []) - Associative array of CSV header names and column names; csvColumnName => aliasColumnName.
  • skipper (string %) - Skip a CSV header and data to import in the table.
  • validate (array []) - Validate a CSV row with Laravel Validation.
  • parsers (array []) - Associative array of column names to parse a value with the given closure.
  • hashable (array ['password']) - Array of column names to hash their values. It uses Hash::make().
  • empty (boolean FALSE) - Set TRUE for keeping an empty value in the CSV file to an empty string instead of a NULL.
  • defaults (array []) - Array of table columns and it's values to seed, when they are empty in the CSV file.
  • timestamps (string/boolean TRUE) - Set Laravel's timestamp in the database while seeding; set as TRUE will use current time.
  • delimiter (string ;) - The used delimiter in the CSV files.
  • chunk (integer 50) - Insert the data of rows every chunk while reading the CSV.
  • encode (boolean TRUE) - Encode the value of rows to UTF-8

Tip

Users of Microsoft Excel can use a macro to export there worksheets to CSV. Easiest is to name your worksheets as table name. Use the following macro to export;

Public Sub SaveWorksheetsAsCsv()
ActiveWorkbook.Save
Dim xWs As Worksheet
Dim xDir As String
Dim folder As FileDialog
Set folder = Application.FileDialog(msoFileDialogFolderPicker)
If folder.Show <> -1 Then Exit Sub
xDir = folder.SelectedItems(1)
For Each xWs In Application.ActiveWorkbook.Worksheets
xWs.SaveAs xDir & "\" & xWs.Name, xlCSV
Next
End Sub

Examples

Table with given timestamps

Give the seeder a specific table name instead of using the CSV filename;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->tablename = 'email_users';
        $this->timestamps = '1970-01-01 00:00:00';
    }

Connection

Give the seeder a specific connection and table name.;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/other_users.csv';
        $this->connection = 'second_db';
        $this->tablename = 'second_users';
    }

Mapping

Map the CSV headers to table columns, with the following CSV;

1,Foo,Bar
2,John,Doe

Handle like this;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->mapping = ['id', 'firstname', 'lastname'];
        $this->header = FALSE;
    }

Aliases with defaults

Seed a table with aliases and default values, like this;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->aliases = ['csvColumnName' => 'table_column_name', 'foo' => 'bar'];
        $this->defaults = ['created_by' => 'seeder', 'updated_by' => 'seeder'];
    }

Skipper

Skip a column in a CSV with a prefix. For example you use id in your CSV and only usable in your CSV editor. The following CSV file looks like so;

%id,first_name,last_name,%id_copy,birthday
1,Foo,Bar,1,1970-01-01
2,John,Doe,2,1980-01-01

The first and fourth value of each row will be skipped with seeding. The default prefix is '%' and changeable to;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->skipper = 'custom_';
    }

Validate

Validate each row of a CSV like this;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->validate = [ 'name'              => 'required',
                            'email'             => 'email',
                            'email_verified_at' => 'date_format:Y-m-d H:i:s',
                            'password'          => ['required', Rule::notIn([' '])]];
    }

Parse

Parse values of certain column when seeding a CSV like this;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->parsers = ['email' => function ($value) { 
            return strtolower($value);
        }];
    }

Hash

Hash values when seeding a CSV like this;

    public function __construct()
    {
        $this->file = '/database/seeds/csvs/users.csv';
        $this->hashable = ['password', 'salt'];
    }
