If you’re interested in looking, the QueryCompiler.parse_expr

have noticed in the above model code that there is a class defined on the base model named Meta that sets the database attribute. Peewee allows every model to specify which database it uses. There are many iterate without caching each model returned, using much less memory when iterating over large result sets. # Let's assume we've got 10 million stat objects to dump to a csv file. stats = Stat.select() # presented below. term (str) – Search term to use. weights – A list of weights for the columns, ordered with respect to the column’s position in the table. Or, a dictionary keyed by the field or field
