您可以创建一个字典,设置参数并将其传递给将字典解包为关键词参数:
field_name = funct()
params = {field_name +'__lte':arg1,#field_name应该还包含字符串
'some_other_field_name':arg2}
位置=位置.objects.filter(** params)
#与(假定为field_name ='some_name')相同:
#Locations.objects.filter(some_name__lte = arg1,some_other_field_name = arg2)
I'd like to call a query with a field name filter that I wont know before run time... Not sure how to construct the variable name ...Or maybe I am tired.
field_name = funct()
locations = Locations.objects.filter(field_name__lte=arg1)
where if funct() returns name would equal to
locations = Locations.objects.filter(name__lte=arg1)
Not sure how to do that ...
You can create a dictionary, set the parameters and pass this to the function by unpacking the dictionary as keyword arguments:
field_name = funct()
params = {field_name + '__lte': arg1, # field_name should still contain string
'some_other_field_name': arg2}
locations = Locations.objects.filter(**params)
# is the same as (assuming field_name = 'some_name'):
# Locations.objects.filter(some_name__lte=arg1, some_other_field_name=arg2)
