Models¶

class indico.modules.categories.models.categories.Category(**kwargs)¶

Bases: indico.core.db.sqlalchemy.searchable.SearchableTitleMixin, indico.core.db.sqlalchemy.descriptions.DescriptionMixin, indico.core.db.sqlalchemy.protection.ProtectionManagersMixin, indico.core.db.sqlalchemy.attachments.AttachedItemsMixin, sqlalchemy.orm.decl_api.Model

An Indico category.

A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

ATTACHMENT_FOLDER_ID_COLUMN = 'category_id'¶

access_key = None¶

acl_entries¶

allow_no_access_contact = True¶

allow_relationship_preloading = True¶

can_create_events(user)¶: Check whether the user can create events in the category.

can_propose_events(user)¶: Check whether the user can propose move requests to the category.

chain_query¶

Get a query object for the category chain.

The query retrieves the root category first and then all the intermediate categories up to (and including) this category.

children¶

deep_children_query¶

Get a query object for all subcategories.

This includes subcategories at any level of nesting.

default_badge_template¶

default_badge_template_id¶

default_event_themes¶

default_render_mode = 2¶

default_ticket_template¶

default_ticket_template_id¶

disallowed_protection_modes = frozenset()¶

display_tzinfo¶: The tzinfo of the category or the one specified by the user.

effective_icon_url¶: Get the HTTP URL of the icon (possibly inherited).

event_creation_mode¶

event_creation_notification_emails¶

event_message¶

event_message_mode¶

get_hidden_events(user=None)¶: Get all hidden events within the given category and user.

classmethod get_icon_data_cte()¶

classmethod get_protection_cte()¶

get_protection_parent_cte()¶

classmethod get_root()¶: Get the root category.

classmethod get_subtree_ids_cte(ids)¶

Create a CTE for a category subtree.

This CTE contains a single id column that contains all the specified IDs and those of all their subcategories.

This is likely to be much more performant than get_tree_cte when the query is used with LIMIT, especially in large databases.

classmethod get_tree_cte(col='id')¶

Create a CTE for the category tree.

The CTE contains the following columns:

id – the category id
path – an array containing the path from the root to

the category itself
is_deleted – whether the category is deleted

Parameters:	col – The name of the column to use in the path or a callable receiving the category alias that must return the expression used for the ‘path’ retrieved by the CTE.

static get_visible_categories_cte(category_id)¶: Get a sqlalchemy select for the visible categories within the given category, including the category itself.

has_effective_icon¶

has_icon¶

has_logo¶

icon¶

icon_metadata¶

icon_url¶: Get the HTTP URL of the icon.

id¶

inheriting_have_acl = True¶

is_deleted¶

is_descendant_of(categ)¶

is_empty¶

is_flat_view_enabled¶

is_root¶

locator¶

Define a smart locator property.

This behaves pretty much like a normal read-only property and the decorated function should return a dict containing the necessary data to build a URL for the object.

This decorator should usually be applied to a method named locator as this name is required for get_locator to find it automatically when just passing the object.

If you need more than one locator, you can define it like this:

@locator_property
def locator(self):
    return {...}

@locator.other
def locator(self):
    return {...}

The other locator can then be accessed by passing obj.locator.other to the code expecting an object with a locator.

log(realm, kind, module, summary, user=None, type_='simple', data=None, meta=None)¶

Create a new log entry for the category.

Parameters:

realm – A value from CategoryLogRealm indicating the realm of the action.
kind – A value from LogKind indicating the kind of the action that was performed.
module – A human-friendly string describing the module related to the action.
summary – A one-line summary describing the logged action.
user – The user who performed the action.
type – The type of the log entry. This is used for custom rendering of the log message/data
data – JSON-serializable data specific to the log type.
meta – JSON-serializable data that won’t be displayed.

Returns:

The newly created EventLogEntry

In most cases the simple log type is fine. For this type, any items from data will be shown in the detailed view of the log entry. You may either use a dict (which will be sorted) alphabetically or a list of key, value pairs which will be displayed in the given order.

logo¶

logo_metadata¶

logo_url¶: Get the HTTP URL of the logo.

move(target: indico.modules.categories.models.categories.Category)¶: Move the category into another category.

Parameters:	n_categs – the number of categories to go up fail_on_overflow – whether to fail if we try to go above the root category
Returns:	Category object or None (only if `fail_on_overflow` is not set)

own_no_access_contact¶

own_visibility_horizon¶: Get the highest category this one would like to be visible from (configured visibility).

parent_chain_query¶

Get a query object for the category’s parent chain.

The query retrieves the root category first and then all the intermediate categories up to (excluding) this category.

parent_id¶

position¶

possible_render_modes = {<RenderMode.markdown: 2>}¶

protection_mode¶

protection_parent¶: The parent object to consult for ProtectionMode.inheriting.
