About

Generate fake but valid data filled databases for test purposes using most popular patterns(AFAIK).
Current support is sqlite, mysql, postgresql, mongodb, redis, couchdb.

Installation

The installation through pypi retrieves ‘fake-factory’ as a main dependency.

pip install fake2db

Optional requirements

PostgreSQL

pip install psycopg2

For psycopg2 to install you need pg_config in your system.

On Mac, the solution is to install postgresql:

brew install postgresql

On CentOS, the solution is to install postgresql-devel:

sudo yum install postgresql-devel

Mongodb

pip install pymongo

Redis

pip install redis

MySQL

mysql connector is needed for mysql db generation:

CouchDB

pip install couchdb

Usage

–rows argument is pretty clear 😃 integer

–db argument takes 6 possible options : sqlite, mysql, postgresql, mongodb, redis, couchdb

–name argument is OPTIONAL. When it is absent fake2db will name db’s randomly.

–host argument is OPTIONAL. Hostname to use for database connection. Not used for sqlite.

–port argument is OPTIONAL. Port to use for database connection. Not used for sqlite.

–username argument is OPTIONAL. Username for the database user.

–password argument is OPTIONAL. Password for database user. Only supported for mysql & postgresql.

–locale argument is OPTIONAL. The localization of data to be generated (‘en_US’ as default).

–seed argument is OPTIONAL. Integer for seeding random generator to produce the same data set between runs. Note: uuid4 values still generated randomly.

fake2db --rows 200 --db sqlite

fake2db --rows 1500 --db postgresql --name test_database_postgre

fake2db --db postgresql --rows 2500 --host container.local --password password --user docker

fake2db --rows 200 --db sqlite --locale cs_CZ --seed 1337

In addition to the databases supported in the db argument, you can also run fake2db with FoundationDB SQL Layer. Once SQL Layer is installed, simply use the postgresql generator and specify the SQL Layer port. For example:

fake2db --rows --db postgresql --port 15432

Custom Database Generation

If you want to create a custom db/table, you have to provide –custom parameter followed by the column item you want. At the point in time, i mapped all the possible column items you can use here:

https://github.com/emirozer/fake2db/blob/master/fake2db/custom.py

Feed any keys you want to the custom flag:

fake2db.py --rows 250 --db mysql --username mysql --password somepassword --custom name date country

fake2db.py --rows 1500 --db mysql --password randompassword --custom currency_code credit_card_full credit_card_provider

fake2db.py --rows 20 --db mongodb --custom name date country

Sample output - SQLite
