37122	JSONField has_changed doesn't reflect disabled correctly	alex		"Problem:

A disabled JSONField still reports changes via has_changed.

Why?

``` python
def has_changed(self, initial, data):
    # here we miss the check for disabled
    if super().has_changed(initial, data):
        return True
    ...

``` 
As we see, has_changed from the base is called and if successful, True is returned. But we have no additional check for disabled.

Fix:

``` python
def has_changed(self, initial, data):
    if self.disabled:
        return False
    if super().has_changed(initial, data):
        return True
    ...

``` 

This corrupts the changed fields in the history of admin."	Uncategorized	new	Uncategorized	6.0	Normal				Unreviewed	1	0	0	0	1	0
