* TypeError int（）参数必须是字符串或数字，而不是'QueryDict' *

    # If we had a POST then get the request post values.
    if request.method == 'POST':
        form = BatchForm(request.POST)
        # Check we have valid data before saving trying to save.
        if form.is_valid():
            # Clean all data and add to var data.
            data = form.cleaned_data
            groups = data['group'].split(",")

您将request.POST作为user参数传递给表单。这样做：

form = BatchForm(data=request.POST)

#  first parameter ---v
def __init__(self, user=None, ...

#  first parameter ---v
form = BatchForm(request.POST)

表单错误int（）参数必须是字符串或数字，而不是'QueryDict'
