Django默认情况下，按字母顺序对模型进行排序。因此，Event应用模型的顺序为Epic、EventHero、EventVillain、Event
假设你希望顺序是
EventHero、EventVillain、Epic、Event。
用于呈现后台indxe页面的模板为admin/index.html，对应的视图函数为 ModelAdmin.index。
def index(self, request, extra_context=None):
"""
Display the main admin index page, which lists all of the installed
apps that have been registered in this site.
"""
app_list = self.get_app_list(request)
context = {
**self.each_context(request),
'title': self.index_title,
'app_list': app_list,
**(extra_context or {}),
}
request.current_app = self.name
return TemplateResponse(request, self.index_template or
'admin/index.html', context)
默认的get_app_list方法用于设置模型的顺序。
def get_app_list(self, request):
"""
Return a sorted list of all the installed apps that have been
registered in this site.
"""
app_dict = self._build_app_dict(request)
# Sort the apps alphabetically.
app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())
# Sort the models alphabetically within each app.
for app in app_list:
app['models'].sort(key=lambda x: x['name'])
return app_list
因此，可以通过覆盖get_app_list方法来修改显示顺序：
class EventAdminSite(AdminSite):
def get_app_list(self, request):
"""
Return a sorted list of all the installed apps that have been
registered in this site.
"""
ordering = {
"Event heros": 1,
"Event villains": 2,
"Epics": 3,
"Events": 4
}
app_dict = self._build_app_dict(request)
# a.sort(key=lambda x: b.index(x[0]))
# Sort the apps alphabetically.
app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())
# Sort the models alphabetically within each app.
for app in app_list:
app['models'].sort(key=lambda x: ordering[x['name']])
return app_list
以上代码app['models'].sort(key=lambda x: ordering[x['name']])用来设置默认顺序。修改后效果如下。
