Generating Models from Existing Databases If you’d like to generate peewee model definitions for an existing database, you can try out the database introspection tool my_postgresql_database Introspecting a SQLite database: python -m pwiz --engine=sqlite test.db pwiz will generate: Database connection object A BaseModel class to use with the database Model classes for each table programs, pskel can really save you time. To generate a script, you can simply run: pskel User Tweet SomeModel AnotherModel > my_script.py pskel will generate code to connect to an in-memory SQLite database

start using peewee with an existing database, you can use pwiz, a model generator to automatically generate model definitions. Fields The Field class is used to describe the mapping of Model attributes IntegerField() class Meta: primary_key = False Table Names By default Peewee will automatically generate a table name based on the name of your model class. The way the table-name is generated depends on the presence of a primary key value. Since, with our uuid example, the database driver won’t generate a new ID, we need to specify it manually. When we call save() for the first time, pass in force_insert
