有没有在每个对象基础上使list_editable可选？例如，readonly fields属性具有此选项，该选项不会影响changelist_view。
class MyAdmin(admin.ModelAdmin):
readonly_fields = ('foo',)
def get_readonly_fields(self, request, obj=None):
fields = super(MyAdmin, self).get_readonly_fields(request, obj=obj)
if obj.status == 'CLOSED':
return fields + ('bar',)
return fields
list_display和其他一些属性也可以实现同样的效果。似乎没有方法'get_list_editable_fields'。
我希望有些行显然是不可变的，但除了引发粗俗错误之外似乎不起作用。我没有找到任何关于该属性的文档
以某种方式可以通过list_display getter呈现小部件吗？
class MyAdmin(admin.ModelAdmin):
list_display = ('get_bar',)
list_editable = ('get_bar',)
def get_bar(self, obj):
return widget or str(obj.bar) # ???
get_bar.allow_tags = True
使用Alasdair的反馈进行更新：
def get_changelist_formset(self, request, **kwargs):
"""
Returns a FormSet class for use on the changelist page if list_editable
is used.
"""
# I run through this code for each row in the changelist, but there's nothing in kwargs, so I don't know how to use the instance as a guide to which fields should be in list_editable?
defaults = {
"formfield_callback": partial(self.formfield_for_dbfield, request=request),
}
defaults.update(kwargs)
return modelformset_factory(
self.model, self.get_changelist_form(request), extra=0,
fields=self.list_editable, **defaults
)

正如您所说，没有get_list_editable方法。
尝试覆盖get_changelist_formset方法。我认为您需要复制整个方法，并更改传递给modelformset_factory的字段列表。

此外，您可以覆盖changelist_view并执行类似的操作：
def changelist_view(self, request, extra_context=None):
resp = super(CustomModelAdmin, self).changelist_view(request, extra_context)
if something:
resp.context_data['cl'].formset = None
return resp

类中没有get_list_editable方法，但是可以很容易地实现它（在ModelAdmin上测试）：
