Question

我想将一些自定义数据传递给django admin中的模板。如何在下面的示例中访问myData？

class MyAdmin(admin.ModelAdmin):
    def get_object(self, request, object_id, form_field=None):
        obj = super().get_object(request, object_id, form_field)
        self.myData = MyModel.objects.filer(id=obj.myData_ID) 
        return obj

在模板中：

{% for p in myData %}
    <p>{{p}}</p>
{% endfor %}

我认为您可以这样做。我没尝试过

class MyAdmin(admin.ModelAdmin):
    def get_object(self, request, object_id, form_field=None):
        obj = super().get_object(request, object_id, form_field)
        return obj

    def render_change_form(self, request, context, *args, **kwargs):
        context['myData'] = MyModel.objects.filer(id=obj.myData_ID) 
        return super(MyAdmin, self).render_change_form(request, context, args, kwargs)

引用StackOverflow：customizing django admin ChangeForm template / adding custom content

您可以尝试以下方法：

 class MyObjectAdmin(admin.ModelAdmin):

     # A template for a very customized change view:
     change_form_template = 'admin/my_change_form.html'

     def get_dynamic_info(self):
         # ...
         pass

     def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        extra_context['osm_data'] = self.get_dynamic_info()
        return super(MyObjectAdmin, self).change_view(
            request, object_id, form_url, extra_context=extra_context,
        )
