Django: Can I create a QueryDict from a dictionary?
How about?
from django.http import QueryDict
ordinary_dict = {'a': 'one', 'b': 'two', }
query_dict = QueryDict('', mutable=True)
query_dict.update(ordinary_dict)
Python has a built in tool for encoding a dictionary (any mapping object) into a query string
params = {'a': 'one', 'b': 'two', }
urllib.urlencode(params)
'a=one&b=two'
http://docs.python.org/2/library/urllib.html#urllib.urlencode
QueryDict
takes a querystring as first param of its contstructor
def __init__(self, query_string, mutable=False, encoding=None):
q = QueryDict('a=1&b=2')
https://github.com/django/django/blob/master/django/http/request.py#L260
Update: in Python3, urlencode has moved to urllib.parse:
from urllib.parse import urlencode
params = {'a': 'one', 'b': 'two', }
urlencode(params)
'a=one&b=two'
Actually a little indirect but more logical way to achieve this is using MultiValueDict. This way multiple values per key can be stored in a QueryDict and .getlist method should then work fine.
from django.http.request import QueryDict, MultiValueDict
dictionary = {'my_age': ['23'], 'my_girlfriend_age': ['25', '27'], }
qdict = QueryDict('', mutable=True)
qdict.update(MultiValueDict(dictionary))
print qdict.get('my_age') # 23
print qdict['my_girlfriend_age'] # 27
print qdict.getlist('my_girlfriend_age') # ['25', '27']
