1.注册主题代码：
import xadmin from xadmin import views class BaseSettings(object): #全站的配置类, 配置主题 enable_themes = True #主题功能,enable_themes=True 表示要使用它的主题功能，xadmin默认是取消掉的,默认只有两个主题 use_bootswatch = True #xadmin默认是取消掉的，显示更多主题，可以打开为True，然后会请求https://bootswatch.com/api/3.json，如果请求失败，就只会显示两个默认的 #请求的代码为 xadmin 下的plugins下的themes.py文件中 if self.use_bootswatch:（大概69行），会请求https://bootswatch.com/api/3.json加载，加载失败会只显示两个主题
xadmin.site.register(views.BaseAdminView,BaseSetting)
themes.py文件中 if self.use_bootswatch:代码如下：
if self.use_bootswatch: ex_themes = cache.get(THEME_CACHE_KEY) print("ex_themes:") print(ex_themes) if ex_themes: themes.extend(json.loads(ex_themes)) else: ex_themes = [] try: h = httplib2.Http() resp, content = h.request("https://bootswatch.com/api/3.json", 'GET', '', headers={"Accept": "application/json", "User-Agent": self.request.META['HTTP_USER_AGENT']}) if six.PY3: content = content.decode() watch_themes = json.loads(content)['themes'] ex_themes.extend([ {'name': t['name'], 'description': t['description'], 'css': t['cssMin'], 'thumbnail': t['thumbnail']} for t in watch_themes]) except Exception as e: print(e) cache.set(THEME_CACHE_KEY, json.dumps(ex_themes), 24 * 3600) themes.extend(ex_themes)
2.问题出现原因：
正常的话，设置use_bootswatch = True 后，应该会显示很多主题，不止两个，但是当if self.use_bootswatch:后的代码进行https://bootswatch.com/api/3.json请求失败后，就会只显示两个
3.解决方法：
3.1. 在浏览器中输入“https://bootswatch.com/api/3.json”，得到内容如下：

可以只要name和css两个字段
3.2. 将use_bootswatch = False,然后赋值user_themes，最终配置如下：
import xadmin from xadmin import views #导入xadmin中的views,用于和 BaseSettings类绑定 class BaseSettings(object): #全站的配置类, 配置主题 enable_themes = True #主题功能,enable_themes=True 表示要使用它的主题功能，xadmin默认是取消掉的,默认只有两个主题 use_bootswatch = False #xadmin默认是取消掉的，显示更多主题，可以打开为True，然后会请求https://bootswatch.com/api/3.json，如果请求失败，就只会显示两个默认的 #请求的代码为 xadmin 下的plugins下的themes.py文件中 if
