django-useful-fields

• TimeZoneField

  This field stores a reference to a time zone in the database and automatically instantiates the correct pytz time

  zone object on retrieval. Useful for recording a user’s default time zone.

• MarkdownCharField

  This field is meant to be used in collaboration with a regular CharField. The regular CharField stores the Markdown-

  formatted source text and this field will store the rendered HTML version of that same text. Use the populate_from

  argument to indicated which field on the same model contains the source text. If the allow_html argument is

  False (the default), any HTML tags present in the source text will be removed using the

  bleach library. The extensions argument can be used to enable any desired

  extensions for the

  Markdown library. One extension is enabled by default:

  SmartyPants. SmartyPants is configured to use the

  correct Unicode characters (e.g. “) rather than HTML entities (e.g. “). Since CharFields don’t normally

  contain paragraphs of text, MarkdownCharField strips the <p></p> tags that Markdown always includes.

• MarkdownTextField

  This field is meant to be used in collaboration with a regular TextField. The regular TextField stores the Markdown-

  formatted source text and this field will store the rendered HTML version of that same text. Use the populate_from

  argument to indicated which field on the same model contains the source text. If the allow_html argument is

  False (the default), any HTML tags present in the source text will be removed using the

  bleach library. The extensions argument can be used to enable any desired

  extensions for the

  Markdown library. One extension is enabled by default:

  SmartyPants. SmartyPants is configured to use the

  correct Unicode characters (e.g. “) rather than HTML entities (e.g. &ldquo;).

• UUIDPrimaryKeyField

  UUIDs are, in many ways, better primary keys than automatically incrementing integer fields. Unfortunately, the

  default Django implementation—UUIDField—requires some boilerplate (including importing the uuid module) before

  it can be used as a primary key. UUIDPrimaryKeyField manages the boilerplate for you. Just add

  id = UUIDPrimaryKeyField()

  to your model and everything will just work.
