[Django]-Django filtering from models: Model.objects.filter(Q())

Here is one way to do it explicitly:

>>> Q_filter = Q()
>>> for value in rows_to_search:
...     Q_filter |= Q(**{"{}__iregex".format(value): search})

Here is one-liner using reduce():

>>> Q_filter = reduce(lambda x, y: x | Q(**{"{}__iregex".format(y): search}), rows_to_search, Q())

Another one-liner using operator.or_ with list comprehensions:

>>> Q_filter = reduce(operator.or_, [Q(**{"{}__iregex".format(key): search}) for key in rows_to_search])

Then you can call the query as follows:

MyModel.objects.filter(Q_filter)
