and combine expressions. Field types table lists the various field types peewee supports and the parameters they accept. There is also an extension module that contains special/custom field types. Contents: vendor-specific parameters easily. For instance, with Postgresql it is common to need to specify the host, user and password when creating your connection. These are not standard Peewee Database parameters, so they user='www-data', charset='utf8mb4') Consult your database driver’s documentation for the available parameters: Postgres: psycopg2 [http://initd.org/psycopg/docs/module.html#psycopg2.connect] MySQL: MySQLdb
