我想将参数{{x}}
传递给我的自定义文件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)
答案 0 :(得分:2)
我想我实际上可以回答这个问题(对于通过谷歌找到这个问题的其他人)。
Django 1.4实际上改变了change_view的定义方式,你可能在互联网上找到的一些文档或片段尚未更新。
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.change_view
换句话说,这应该有效:
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, form_url='', extra_context=None):
context = {}
context.update(extra_context or {})
context.update({ 'x': get_osm_info(),})
return super(MyModelAdmin, self).change_view(request, object_id, form_url, context)
