Jinja2是人气Web框架Flask中的内置模板引擎,而且与Django的模板引擎比较类似,这里我们就来看一下为Python的Tornado框架配置使用Jinja2模板引擎的方法

tornado 默认有一个模板引擎但是功能简单(其实我能用到的都差不多)使用起来颇为麻烦, 而jinja2语法与django模板相似所以决定使用他.

下载jinja2

还是用pip 下载(用的真是爽)

pip install jinja2
Copy after login

这样就可以使用了.

tornado与jinja2 整合

tornado和jinja2整合起来很简单(其实是网上找的比较简单), 不知道从那里找到的反正找到了,不说了直接上代码

#coding:utf-8

import tornado.web
from jinja2 import Environment, FileSystemLoader, TemplateNotFound

class TemplateRendring(object):
  """
  A simple class to hold methods for rendering templates.
  """
  def render_template(self, template_name, **kwargs):
    template_dirs = []
    if self.settings.get('template_path', ''):
      template_dirs.append(self.settings['template_path'])
    env = Environment(loader=FileSystemLoader(template_dirs))

    try:
      template = env.get_template(template_name)
    except TemplateNotFound:
      raise TemplateNotFound(template_name)
    content = template.render(kwargs)
    return content 

# 就是重新写 BaseHandler 由jinja2模板渲染
class BaseHandler(tornado.web.RequestHandler, TemplateRendering):
  """
  Tornado RequestHandler subclass.
  """
  def initialize(self):
    pass

  def get_current_user(self):
    user = self.get_secure_cookie('user')
    return user if user else None

  def render_html(self, template_name, **kwargs):
    kwargs.update({
      'settings': self.settings,
      'STATIC_URL': self.settings.get('static_url_prefix', '/static/'),
      'request': self.request,
      'current_user': self.current_user,
      'xsrf_token': self.xsrf_token,
      'xsrf_form_html': self.xsrf_form_html,
    })
    content = self.render_template(template_name, **kwargs)
    self.write(content)
Copy after login

这样就可以在tornado中替换self.render为self.render_html了.
