1.7.0

Arrays of Date / Time / Timestamp / Timestamptz now work in SQLite.

For example:

class MyTable(Table):
    times = Array(Time())
    dates = Array(Date())
    timestamps = Array(Timestamp())
    timestamps_tz = Array(Timestamptz())

1.6.0

Added support for a bunch of Postgres functions, like Upper, Lower, Length, and Ltrim. They can be used in select queries:

from piccolo.query.functions.string import Upper

>>> await Band.select(Upper(Band.name, alias="name"))
[{"name": "PYTHONISTAS"}]

And also in where clauses:

>>> await Band.select().where(Upper(Band.manager.name) == 'GUIDO')
[{"name": "Pythonistas"}]

Full Changelog: 1.4.2...1.5.0

1.4.2

Improved how ModelBuilder handles recursive foreign keys.

1.4.1

Fixed an edge case with auto migrations.

If starting from a table like this, with a custom primary key column:

class MyTable(Table):
    id = UUID(primary_key=True)

When a foreign key is added to the table which references itself:

class MyTable(Table):
    id = UUID(primary_key=True)
    fk = ForeignKey("self")

The auto migrations could fail in some situations.

1.4.0

Improved how create_pydantic_model handles Array columns:

• Multidimensional arrays (e.g. Array(Array(Integer))) have more accurate types.
• Array(Email()) now validates that each item in the list is an email address.
• Array(Varchar(length=10)) now validates that each item is the correct length (i.e. 10 in this example).

Other changes

Some Pylance errors were fixed in the codebase.

1.3.2

Fixed a bug with nested array columns containing BigInt. For example:

class MyTable(Table):
    my_column = Array(Array(BigInt))

Thanks to @AmazingAkai for reporting this issue.

1.3.1

Fixed a bug with foreign keys which reference BigSerial primary keys. Thanks to @Abdelhadi92 for reporting this issue.
