I need to prepare filter with dynamic fields.. I don't know the field name so i need to give it dynamically. here what i tried so far,

gen_query = reduce(operator.or_, (Q(eval('%s=i' % (field, i))) for i in request.query_params.get(field).split(',')))

but it raising syntax error!

You can create dict with parameters and unpack it in Q constructor:

gen_query = reduce(operator.or_, (Q(**{field: i}) for i in request.query_params.get(field).split(',')))

Could you use Q('{}={}'.format(field, i)) if you need string formatting?
