classmethod check(**kwargs)

clean()

Hook for doing any extra model-wide validation after clean() has been called on every field by self.clean_fields. Any ValidationError raised by this method will not be associated with a particular field; it will have a special-case association with the field defined by NON_FIELD_ERRORS.

clean_fields(exclude=None)

Clean all fields and raise a ValidationError containing a dict of all validation errors if any occur.

created_by

Type: ForeignKey to User

Creator. The account that created this external calendar. (related name: externalcalendar)

created_by_id

Internal field, use created_by instead.

date_error_message(lookup_type, field_name, unique_for)

delete(using=None, keep_parents=False)

errors

Type: CharField

Import errors

events

Type: Reverse ForeignKey from Event

All events of this external calendar (related name of external_calendar)

classmethod from_db(db, field_names, values)

full_clean(exclude=None, validate_unique=True, validate_constraints=True)

Call clean_fields(), clean(), validate_unique(), and validate_constraints() on the model. Raise a ValidationError for any errors that occur.

get_constraints()

get_deferred_fields()

Return a set containing names of deferred fields for this instance.

classmethod get_model_name_plural() → str

Get the plural representation of this model name

Returns:

The plural model name

Return type:

str

get_next_by_last_changed_on(*, field=<django.db.models.DateTimeField: last_changed_on>, is_next=True, **kwargs)

Finds next instance based on last_changed_on. See get_next_by_FOO() for more information.

get_previous_by_last_changed_on(*, field=<django.db.models.DateTimeField: last_changed_on>, is_next=False, **kwargs)

Finds previous instance based on last_changed_on. See get_previous_by_FOO() for more information.

get_repr() → str

This overwrites the default Django __repr__() method

Returns:

The canonical string representation of the external calendar

Return type:

str

id

Type: BigAutoField

Primary key: ID

import_filter_category

Type: CharField

The category that events need to have to get imported (Leave blank to import all events)

last_changed_by

Type: ForeignKey to User

Last changed by. The account that was the last to change this external calendar. (related name: +)

last_changed_by_id

Internal field, use last_changed_by instead.

last_changed_on

Type: DateTimeField

Last changed on

load_ical() → Calendar

Loads the url and creates an icalendar :return: The Icalendar returned by the url :raises OSError: If the url cannot be loaded :raises ValueError: If the data are not valid icalendar format

Return type:

Calendar

name

Type: CharField

Calendar name

objects = <django.db.models.Manager object>

property pk

prepare_database_save(field)

refresh_from_db(using=None, fields=None)

Reload field values from the database.

By default, the reloading happens from the database this instance was loaded from, or by the read router if this instance wasn’t loaded from any database. The using parameter will override the default.

Fields can be used to specify which fields to reload. The fields should be an iterable of field attnames. If fields is None, then all non-deferred fields are reloaded.

When accessing deferred fields of an instance, the deferred loading of the field will call this method.

region

Type: ForeignKey to Region

Region (related name: external_calendars)

region_id

Internal field, use region instead.

save(force_insert=False, force_update=False, using=None, update_fields=None)

Save the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.

save_base(raw=False, force_insert=False, force_update=False, using=None, update_fields=None)

Handle the parts of saving which should be done only once per save, yet need to be done in raw saves, too. This includes some sanity checks and signal sending.

The ‘raw’ argument is telling save_base not to save any parent models and not to do any changes to the values before save. This is used by fixture loading.

serializable_value(field_name)

Return the value of the field name for this instance. If the field is a foreign key, return the id value instead of the object. If there’s no Field object with this name on the model, return the model attribute’s value.

Used to serialize a field’s value (in the serializer, or form output, for example). Normally, you would just access the attribute directly and not use this method.

unique_error_message(model_class, unique_check)

url

Type: URLField

URL

validate_constraints(exclude=None)

validate_unique(exclude=None)

Check unique constraints on the model and raise ValidationError if any failed.
