Question

我在使用https://github.com/Khan/gae_mini_profiler在我的应用中正常工作时遇到了问题。

我已经仔细按照说明操作，这是我的应用程序（不必要的东西被剥离了。）

ERROR    2015-05-21 20:23:25,460 wsgi.py:263] 
Traceback (most recent call last):

  File "/Users/jedc/mypathtomyapp/main.py", line 33, in <module>
'profiler_includes': gae_mini_profiler.templatetags.profiler_includes,
AttributeError: 'module' object has no attribute 'templatetags'

我收到了这个错误：

  File "/Users/jedc/Dropbox (Personal)/code/seeddb-devbranch/seeddbapp/main.py", line 22, in get
self.render(templateid, context)
  File "/Users/jedc/Dropbox (Personal)/code/seeddb-devbranch/seeddbapp/handlers.py", line 64, in render
self.response.write(self.jinja2.render_template(template_name, **values))
  File "/Users/jedc/google-cloud-sdk/platform/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.1/webapp2_extras/jinja2.py", line 158, in render_template
return self.environment.get_template(_filename).render(**context)
  File "/Users/jedc/google-cloud-sdk/platform/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/jinja2-2.6/jinja2/environment.py", line 894, in render
return self.environment.handle_exception(exc_info, True)
  File "templates/base.html", line 118, in template
    {% profiler_includes %}
TemplateSyntaxError: Encountered unknown tag 'profiler_includes'.

这可能是因为我在主应用程序中使用webapp2而不是webapp吗？或者我应该以不同方式导入gae_mini_profiler？我无法理解。

更新

在专门导入gae_mini_profiler.templatetags之后，我现在遇到了一个新错误。

  </div>
  {% profiler_includes %}
  </body>
</html>

并且base.html的结尾有：

{% profiler_includes %}

现在，如果我改变：

{{ profiler_includes }}

为：

<!DOCTYPE html>

<html lang="en">

        <meta charset="utf-8"/>
        <title>jeKnowledge's Interative Website</title>

</html>

它清除了错误，但实际上似乎没有触发该功能。

我不是 Jinja2专家，但是当我在webapp2_extras.jinja2.default_config部分定义该函数时，我是否指定了错误的内容？

Answer 1

你错过了一个import语句。您应该明确地导入gae_mini_profiler.templatetags，因为您正在使用它。

import gae_mini_profiler.templatetags

Answer 2

关于更新：

这：{{ profiler_includes() | safe }}

而不是：{% profiler_includes %}

是我最终能够在python2.7 / jinja2中使用gae_mini_profiler包含的...

正确配置gae_mini_profiler时出现问题

更新
