The watcher.objects.strategy Module

class watcher.objects.strategy.Strategy(context, **kwargs)

Bases: watcher.objects.base.WatcherObject

create(context=None)

Create a Strategy record in the DB.

Parameters:context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)

destroy(context=None)

Delete the Strategy from the DB.

Parameters:context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)

classmethod get(context, strategy_id)

Find a strategy based on its id or uuid

Parameters:

• context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)
• strategy_id – the id or uuid of a strategy.

Returns:

a Strategy object.

classmethod get_by_id(context, strategy_id)

Find a strategy based on its integer id

Parameters:

• context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)
• strategy_id – the id of a strategy.

Returns:

a Strategy object.

classmethod get_by_name(context, name)

Find a strategy based on name

Parameters:

• name – the name of a strategy.
• context – Security context

Returns:

a Strategy object.

classmethod get_by_uuid(context, uuid)

Find a strategy based on uuid

Parameters:

• context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)
• uuid – the uuid of a strategy.

Returns:

a Strategy object.

classmethod list(context, limit=None, marker=None, filters=None, sort_key=None, sort_dir=None)

Return a list of Strategy objects.

Parameters:

• context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)
• filters – dict mapping the filter key to a value.
• limit – maximum number of resources to return in a single result.
• marker – pagination marker for large data sets.
• sort_key – column to sort results by.
• sort_dir – direction to sort. “asc” or “desc”.

Returns:

a list of Strategy object.

refresh(context=None)

Loads updates for this Strategy.

Loads a strategy with the same uuid from the database and checks for updated attributes. Updates are applied from the loaded strategy column by column, if there are any updates.

Parameters:context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)

save(context=None)

Save updates to this Strategy.

Updates will be made column by column based on the result of self.what_changed().

Parameters:context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)

soft_delete(context=None)

Soft Delete the Strategy from the DB.

Parameters:context – Security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: Strategy(context)
