Django 条件管理员 list_editable

Question

有没有办法让 list_editable 在每个对象的基础上可选？例如 readonly fields 属性有这个选项，它不影响 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。好像没有方法'get_list_editable_fields'。

我显然希望某些行是不可变的，但除了引发粗俗的错误之外似乎不起作用。我也没有找到有关该属性的任何文档

是否可以通过 list_display getter 以某种方式呈现小部件？

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

根据 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
    )

Answer 1

正如你所说，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

Answer 2

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

Answer 3

如前所述，ModelAdminclass中没有get_list_editable方法，但可以很容易地实现（在django==2.1上测试）：

class MyAdminClass(admin.ModelAdmin):

    def get_list_editable(self, request):
        """
        get_list_editable method implementation, 
        django ModelAdmin doesn't provide it.
        """
        dynamically_editable_fields = ('name', 'published', )
        return dynamically_editable_fields

    def get_changelist_instance(self, request):
        """
        override admin method and list_editable property value 
        with values returned by our custom method implementation.
        """
        self.list_editable = self.get_list_editable(request)
        return super(MyAdminClass, self).get_changelist_instance(request)
