Applies a filter on the alias given.
Expects the alias of the ORM-class on which to filter, and filter_spec.
Filter_spec contains the specification on the filter.
Expects:
:param operator: The operator to apply, see below for further details
:param value:
The value for the right side of the expression,
the value you want to compare with.
:param path: The path leading to the value
:param attr_key: Boolean, whether the value is in a json-column,
or in an attribute like table.
Implemented and valid operators:
* for any type:
* == (compare single value, eg: '==':5.0)
* in (compare whether in list, eg: 'in':[5, 6, 34]
* for floats and integers:
* >
* <
* <=
* >=
* for strings:
* like (case - sensitive), for example
'like':'node.calc.%' will match node.calc.relax and
node.calc.RELAX and node.calc. but
not node.CALC.relax
* ilike (case - unsensitive)
will also match node.CaLc.relax in the above example
.. note::
The character % is a reserved special character in SQL,
and acts as a wildcard. If you specifically
want to capture a ``%`` in the string, use: ``_%``
* for arrays and dictionaries (only for the
SQLAlchemy implementation):
* contains: pass a list with all the items that
the array should contain, or that should be among
the keys, eg: 'contains': ['N', 'H'])
* has_key: pass an element that the list has to contain
or that has to be a key, eg: 'has_key':'N')
* for arrays only (SQLAlchemy version):
* of_length
* longer
* shorter
All the above filters invoke a negation of the
expression if preceded by **~**::
# first example:
filter_spec = {
'name' : {
'~in':[
'halle',
'lujah'

.. deprecated:: 3.0
Use the helper method :py:func:`aiida_quantumespresso.utils.restart.create_restart_cp` or
:py:func:`aiida_quantumespresso.utils.restart.create_restart_pw` instead,
that returns a calculation builder rather than a new, unstored calculation.
:param bool force_restart: restart also if parent is not in FINISHED
state (e.g. FAILED, IMPORTED, etc.). Default=False.
:param bool parent_folder_symlink: if True, symlinks are used
instead of hard copies of the files. Default given by
self._default_symlink_usage.
:param bool use_output_structure: if True, the output structure
of the restarted calculation is used if available, rather than its
input structure. Useful for nscf or bands calculations, but it
SHOULD NOT be used for the restart of a relaxation run.
Default=False.
:param bool restart_from_beginning: If set to True, creates a copy of
the parent calculation, without using the scratch for the restart.
Useful to restart calculations that have crashed on the cluster for
external reasons. Default=False
