The horizon.tables.actions Module

class horizon.tables.actions.Action(single_func=None, multiple_func=None, handle_func=None, attrs=None, **kwargs)[source]

Bases: horizon.tables.actions.BaseAction

Represents an action which can be taken on this table’s data.

horizon.tables.actions.name

Required. The short name or “slug” representing this action. This name should not be changed at runtime.

horizon.tables.actions.verbose_name

A descriptive name used for display purposes. Defaults to the value of name with the first letter of each word capitalized.

horizon.tables.actions.verbose_name_plural

Used like verbose_name in cases where handles_multiple is True. Defaults to verbose_name with the letter “s” appended.

horizon.tables.actions.method

The HTTP method for this action. Defaults to POST. Other methods may or may not succeed currently.

horizon.tables.actions.requires_input

Boolean value indicating whether or not this action can be taken without any additional input (e.g. an object id). Defaults to True.

horizon.tables.actions.preempt

Boolean value indicating whether this action should be evaluated in the period after the table is instantiated but before the data has been loaded.

This can allow actions which don’t need access to the full table data to bypass any API calls and processing which would otherwise be required to load the table.

horizon.tables.actions.allowed_data_types

A list that contains the allowed data types of the action. If the datum’s type is in this list, the action will be shown on the row for the datum.

Default to be an empty list ([]). When set to empty, the action will accept any kind of data.

horizon.tables.actions.policy_rules

list of scope and rule tuples to do policy checks on, the composition of which is (scope, rule)

scope: service type managing the policy for action rule: string representing the action to be checked

for a policy that requires a single rule check:
policy_rules should look like
“((“compute”, “compute:create_instance”),)”
for a policy that requires multiple rule checks:
rules should look like
“((“identity”, “identity:list_users”),
(“identity”, “identity:list_roles”))”

At least one of the following methods must be defined:

horizon.tables.actions.single(self, data_table, request, object_id)

Handler for a single-object action.

horizon.tables.actions.multiple(self, data_table, request, object_ids)

Handler for multi-object actions.

horizon.tables.actions.handle(self, data_table, request, object_ids)

If a single function can work for both single-object and multi-object cases then simply providing a handle function will internally route both single and multiple requests to handle with the calls from single being transformed into a list containing only the single object id.

Action.get_param_name()[source]

Returns the full POST parameter name for this action.

Defaults to {{ table.name }}__{{ action.name }}.

class horizon.tables.actions.BaseAction(**kwargs)[source]

Bases: horizon.utils.html.HTMLElement

Common base class for all Action classes.

BaseAction.allowed(request, datum)[source]

Determine whether this action is allowed for the current request.

This method is meant to be overridden with more specific checks.

BaseAction.associate_with_table(table)[source]
BaseAction.base_options = {'__module__': 'horizon.tables.actions', 'data_type_matched': <function data_type_matched at 0x531c848>, 'get_default_classes': <function get_default_classes at 0x531c5f0>, 'update': <function update at 0x531c668>, 'get_policy_target': <function get_policy_target at 0x531c8c0>, 'associate_with_table': <function associate_with_table at 0x531c1b8>, '_allowed': <function _allowed at 0x531c758>, '__repr__': <function __repr__ at 0x531c230>, 'allowed': <function allowed at 0x531c578>, 'get_default_attrs': <function get_default_attrs at 0x531c7d0>, 'base_options': {...}, '__doc__': 'Common base class for all ``Action`` classes.', '__init__': <function __init__ at 0x531c9b0>}
BaseAction.data_type_matched(datum)[source]

Method to see if the action is allowed for a certain type of data. Only affects mixed data type tables.

BaseAction.get_default_attrs()[source]

Returns a list of the default HTML attributes for the action. Defaults to returning an id attribute with the value {{ table.name }}__action_{{ action.name }}__{{ creation counter }}.

BaseAction.get_default_classes()[source]

Returns a list of the default classes for the action. Defaults to ["btn", "btn-small"].

BaseAction.get_policy_target(request, datum)[source]

Provide the target for a policy request.

This method is meant to be overridden to return target details when one of the policy checks requires them. E.g., {“user_id”: datum.id}

BaseAction.update(request, datum)[source]

Allows per-action customization based on current conditions.

This is particularly useful when you wish to create a “toggle” action that will be rendered differently based on the value of an attribute on the current row’s data.

By default this method is a no-op.

class horizon.tables.actions.BaseActionMetaClass[source]

Bases: type

Metaclass for adding all actions options from inheritance tree to action. This way actions can inherit from each other but still use the class attributes DSL. Meaning, all attributes of Actions are defined as class attributes, but in the background, it will be used as parameters for the initializer of the object. The object is then initialized clean way. Similar principle is used in DataTableMetaclass.

class horizon.tables.actions.BatchAction(**kwargs)[source]

Bases: horizon.tables.actions.Action

A table action which takes batch action on one or more objects. This action should not require user input on a per-object basis.

horizon.tables.actions.name

An internal name for this action.

horizon.tables.actions.action_present

String or tuple/list. The display forms of the name. Should be a transitive verb, capitalized and translated. (“Delete”, “Rotate”, etc.) If tuple or list - then setting self.current_present_action = n will set the current active item from the list(action_present[n])

You can pass a complete action name including ‘data_type’ by specifying ‘%(data_type)s’ substitution in action_present (“Delete %(data_type)s”). Otherwise a complete action name is a format of “<action> <data_type>”. <data_type> is determined based on the number of items. By passing a complete action name you allow translators to control the order of words as they want.

horizon.tables.actions.action_past

String or tuple/list. The past tense of action_present. (“Deleted”, “Rotated”, etc.) If tuple or list - then setting self.current_past_action = n will set the current active item from the list(action_past[n])

horizon.tables.actions.data_type_singular

A display name for the type of data that receives the action. (“Key Pair”, “Floating IP”, etc.)

horizon.tables.actions.data_type_plural

Optional plural word for the type of data being acted on. Defaults to appending ‘s’. Relying on the default is bad for translations and should not be done.

horizon.tables.actions.success_url

Optional location to redirect after completion of the delete action. Defaults to the current page.

BatchAction.action(request, datum_id)[source]

Required. Accepts a single object id and performs the specific action.

Return values are discarded, errors raised are caught and logged.

Returns a list of dictionaries describing the fixed buttons to use for filtering.

Each list item should be a dict with the following keys:

LinkAction.get_link_url(datum=None)[source]

Returns the final URL based on the value of url.

If url is callable it will call the function. If not, it will then try to call reverse on url. Failing that, it will simply return the value of url as-is.

When called for a row action, the current row data object will be passed as the first parameter.

LinkAction.name = 'link'
LinkAction.render()[source]
