Django: How to limit size of uploaded image when using a ModelForm?

I have in my model an ImageField, and I am using forms.ModelForm to edit the form. I didn't find a way to make the ModelForm limit the uploaded image file size

Although this post is 2 years old, I come across to have a similar situation where even I raise the error, the file is still uploaded. What I have done to solve this is to replace the request.FILES['file'] with None, something like this:

#The max size in bytes
MAX_SIZE = 1000
for filename, file in request.FILES.iteritems():
    if request.FILES['file'].size > MAX_SIZE:
        request.FILES.pop(filename, None)
        # return your errors here

and this solves the issue, the file will not be uploaded. Hope this helps others who come across with similar problem.

Modern browser support client side file size checking. The big advantage is that you can reject a file before it has been uploaded.

if (typeof FileReader !== "undefined") {
    var size = document.getElementById('myfile').files[0].size;
    // check file size
}

Here is some info about it: http://docs.djangoproject.com/en/1.2/topics/http/file-uploads/

Something like this:

#The max size in bytes
MAX_SIZE = 1000
if request.FILES['file'].size > MAX_SIZE:
    #Lauch error
