118 Translate a dictionary of attributes to a nested set of parameters suitable for QuerySet filtering. For example:
119
120 {
121 "name": "Foo",
122 "rack": {
123 "facility_id": "R101"
124 }
125 }
126
127 Becomes:
128
129 {
130 "name": "Foo",
131 "rack__facility_id": "R101"
132 }
133
134 And can be employed as filter parameters:
135
136 Device.objects.filter(**dict_to_filter(attrs_dict))
137 """
138 params = {}
139 for key, val in d.items():
140 k = prefix + key
141 if isinstance(val, dict):
142 params.update(dict_to_filter_params(val, k + '__'))
143 else:
144 params[k] = val
145 return params
