Modify data incoming to django form before cleaning

Question

I need do modify data incoming to Form before cleaning. I made it work, but It looks awful:

    def __init__(self, *args, **kwargs):
        if          


        

Answer 1

I found another solution:

def clean(self, *args, **kwargs):
    data = dict(self.data)
    if 'content' in data:
        content = data['content']
        if isinstance(content, list):
            content = content[0] # QueryDict wraps even single values to list
        data['content'] = ' '.join(content.strip().split())
    self.data = data # I do this trick becouse request.POST is immutable
    return super(MyForm, self).clean(*args, **kwargs)

UPD: error fix: super(self.__class__, self) may cause infinite recursion if I use form inheritance :).

UPD: seems still have troubles, and not work correctly.
