/post does not return multiple values with same key in form data

I took a look at what was going on, and it seems that the cause of the problem is the Flask response form-data MultiDict being converted to json.

It behaves like a normal dict thus all dict functions will only return the first value when multiple values for one key are found.

So by converting it to json, multiple values for the same key are lost.

One solution would be to put multiple values for the same keys into lists, thus making them representable in json:

form = {}
for key in request.form.keys():
    values = request.form.getlist(key)
    if len(values) == 1:
        form[key] = values[0]
    else:
        form[key] = values

Correct. This is what we do in requests (except reverse).

That's what to_dict method does:

to_dict(flat=True)
    Return the contents as regular dict. If flat is True the returned dict will only have the first item present, if flat is False all values
will be returned as lists.

Thanks piotr, didn't see that method.
