我想将一个参数传递{{x}}给我的自定义文件 change_form.html,该文件位于/home/django/project/app/template/admin/change_form.html. 我找到了这段代码,但它不起作用:
class MyModelAdmin(admin.ModelAdmin):
    # A template for a very customized change view:
    change_form_template = 'admin/change_form.html'
    def get_osm_info(self):
        z = Klass()
        x = z.final_down()
        return x
    def change_view(self, request, object_id, extra_context=None):
        my_context = { 'x': get_osm_info(),}
        return super(MyModelAdmin, self).change_view(request, object_id,extra_context=my_context)
