class MarkdownxField(models.TextField):
"""
Custom Django field for Markdown text.
Parameters are identical to those of the ordinary Django **TextField** parameters for the model
fields. For consistency therefore, the descriptions have been borrowed from Django's official
documentations (with minor modifications).
:param verbose_name: A human-readable name for the field. If the verbose name isn't given,
Django will automatically create it using the field's attribute name,
converting underscores to spaces.
:type verbose_name: str
:param blank: If ``True``, the field is allowed to be blank. Default is ``False``.
:type blank: bool
:param null: If ``True``, Django will store empty values as **NULL** in the database.
Default is ``False``.
:type null: bool
:param editable: If ``False``, the field will not be displayed in the admin or any other
ModelForm. They are also skipped during model validation. Default is ``True``.
:type editable: bool
:param help_text: Extra "help" text to be displayed with the form widget. It's useful for
documentation even if your field isn't used on a form. Note that this value
is not HTML-escaped in automatically-generated forms. This lets you include
HTML in ``help_text`` if you so desire.
:type help_text: str
:param validators: A list of validators to run for this field. See the validators_ documentations
for additional information.
:type validators: list, tuple
:param error_messages: The error_messages argument lets you override the default messages that the field
will raise. Pass in a dictionary with keys matching the error messages you want
to override. Relevant error message keys include ``null``, ``blank``,
and ``invalid``.
:type error_messages: dict
:param kwargs: Other ``django.db.models.field`` parameters. See Django documentations_ for additional
information.
