djblets.util.serializers¶

Utilities for serializing content.

class DjbletsJSONEncoder(strip_datetime_ms: bool = True, *args, **kwargs)[source]¶

Bases: DjangoJSONEncoder

A JSON encoder that supports lazy strings, datetimes, and other objects.

This is a specialization of DjangoJSONEncoder the does the following:

• Removes the milliseconds and microseconds from datetimes (unless setting strip_datetime_ms=False when constructing the encoder). This is to help keep timestamps from appearing too new when compared against data coming from a MySQL database (which historically, and by default, chops off milliseconds).

• Serializes objects (including Django models with) containing a to_json method.

__init__(strip_datetime_ms: bool = True, *args, **kwargs) → None[source]¶

Initialize the encoder.

Parameters:

strip_datetime_ms (bool, optional) –

Determines whether milliseconds should be stripped from a datetime.

This is True by default, to preserve the old behavior of the encoder.

strip_datetime_ms: bool¶

Whether milliseconds should be stripped from a datetime.

Type:

bool

__annotations__ = {'strip_datetime_ms': 'bool'}¶

default(obj: SerializableJSONValue) → SerializableJSONValue[source]¶

Encode the object into a JSON-compatible structure.

The result from this will be re-encoded as JSON.

Parameters:

obj (object) – The object to encode.

Returns:

A JSON-compatible value, or a value that can be serialized to JSON through this encoder.

Return type:

object
