DESCRIPTION
DESCRIPTION
This module adds a partition(self, accessor) method to every model. It
accepts for accessor any parameter that would be accepted by mapped,
i.e. a string "field(.subfield)\*" or a function (lambda x: not x.b). It
returns a dictionary with keys that are equal to
set(record.mapped(accessor)), and with values that are recordsets (these
recordsets forming a partition of the initial recordset, conveniently).

So if we have a recordset (x \| y \| z ) such that x.f == True, y.f ==
z.f == False, then (x \| y \| z ).partition("f") == {True: x, False: (y
\| z)}.

Public methods (3)
  • batch(self, batch_size=None)
    Yield successive batches of size batch_size, or .
  • partition(self, accessor)
    Returns a dictionary forming a partition of self into a dictionary value/recordset for each value obtained from the accessor. The accessor itself can be either a string that can be passed to mapped, or an arbitrary function. Note that it is always at least as fast to pass a function, hence the current implementation. If we have a 'field.subfield' accessor such that subfield is not a relational then the result is a list (not hashable). Then the str(key) are used. In the general case a value could both not be hashable nor stringifiable, in a which case this function would crash.
  • read_per_record(self, fields=None, load='_classic_read')
