所以我在这上面撞墙.我觉得我已经解释了我发现的文档和示例,但这似乎不会消失.
这是标签代码:
from google.appengine.ext import webapp
register = webapp.template.create_template_register()
def test_tag():
return "TEST!"
register.simple_tag(test_tag)
这是主要代码:
from google.appengine.ext import webapp
from google.appengine.ext.webapp import util, template
webapp.template.register_template_library('my_tags')
class MainHandler(webapp.RequestHandler):
def get(self):
self.response.out.write(template.render("test.html", {}))
def main():
application = webapp.WSGIApplication([('/', MainHandler)], debug=True)
util.run_wsgi_app(application)
if __name__ == '__main__':
main()
这是模板:
{% load my_tags %}
<html>{% test_tag %}></html>
这是错误:
File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django/django/template/defaulttags.py", line 750, in load
raise TemplateSyntaxError, "'%s' is not a valid tag library: %s" % (taglib, e)
