I have a jquery client that is sending a POST request with a multidimensional array, something like this:
friends[0][id] 12345678 friends[0][name] Mr A friends[1][id] 78901234 friends[1][name] Mr B
That is, an array of two items, name and id.
Is there an automatic way to receive this input as list or a dictionary? I can't seem to be able to make .getlist work
DrMeers' link is no longer valid, so I'll post another method of achieving the same thing. It's also not perfect, and it would be much better if Django had such a function built-in. But, since it doesn't:
Converting Multi-dimensional Form Arrays in Django
Disclaimer: I wrote that post. The essence of it is in this function, which could be more robust, but it works for arrays of one-level objects:
def getDictArray(post, name):
dic = {}
for k in post.keys():
if k.startswith(name):
rest = k[len(name):]
# split the string into different components
parts = [p[:-1] for p in rest.split('[')][1:]
print parts
id = int(parts[0])
# add a new dictionary if it doesn't exist yet
if id not in dic:
dic[id] = {}
# add the information to the dictionary
dic[id][parts[1]] = post.get(k)
return dic
This is related with that question. As stated there, I made special library for Django/Python to handle multidimensional arrays sent through requests. You can find it on GitHub here.
Does this help? http://dfcode.com/blog/2011/1/multi-dimensional-form-arrays-and-django/
If you want POST data, the only way to get it is to specify the exact ‘name’ you are looking for:
person[1].name = request.POST['person[1][name]'] person[1].age = request.POST['person[1][age]'] person[2].name = request.POST['person[2][name]'] person[2].age = request.POST['person[2][age]']
Here is a quick on-the-fly workaround in Python when you have the need to extract form values without explicitly typing the full name as a string:
person_get = lambda *keys: request.POST[ 'person' + ''.join(['[%s]' % key for key in keys])]
Now when you need information, throw one of these suckers in and you’ll have much wider flexibility. Quick example:
person[1].name = person_get('1', 'name') person[1].age = person_get('1', 'age') person[2].name = person_get('2', 'name') person[2].age = person_get('2', 'age')
