18553	Django multipart parser creates mutable QueryDict	k_bx	fred	"When you send multipart request (which, unfortunately, is sent every time your testclient does POST-request https://code.djangoproject.com/ticket/18552 ), your view will get request.POST to be QueryDict with request.POST._mutable == True.

This caused me to write test that passes (sends POST-request and modifies request.POST in view), but production that fails."	Bug	closed	HTTP handling	1.4	Normal	duplicate		k_bx fred	Accepted	0	0	0	0	0	0
