我一直在尝试用python字典呈现html模板。在

实际上，我为我的网页创建了一个站点地图，并用{{%extends%}}标记实现了它。
我想达到的解决方案是为每个网站创建一个字典，它可以用CherryPy访问，并用Jinja呈现。过程如下：

  1. 我用需要的变量创建了一个字典
  2. 将字典传递给附加了静态变量（sitemap）的附加函数。在

我尝试的第一个解决方案是将字典转换为字符串并返回字符串并呈现它。在

import cherrypy
import os
from jinja2 import Environment, FileSystemLoader
BASE_PATH = os.path.dirname(os.path.abspath(__file__))+"\\static"
print BASE_PATH
env = Environment(loader=FileSystemLoader(BASE_PATH))


class Main(object):
    def __init__(self):
        self.sites = {"main": "index",
                      "leroy": "leroy"}

def render_pages(self, template, dict):
    dictItemCount = len(dict)
    dictPosition = 1
    string=""
    for current in dict:
        if(dictPosition == dictItemCount):
            print 'last item in dictionary'
            string += str(current)+"="+"'"+str(dict[current])+"'"
            break
        dictPosition += 1
        string += str(current)+"="+"'"+str(dict[current])+"', "
    return template.render(>>>PROBLEM HERE<<<)

@cherrypy.expose
def leroy(self):
    tmpl = env.get_template('leroy.html')
    jahre = 24
    monate = jahre*12
    tage = monate*30
    stunden = tage*24
    minuten = stunden*60
    sekunden = minuten*60
    variables = {jahre: jahre,
                 monate: monate,
                 tage: tage,
                 stunden: stunden,
                 sekunden: sekunden}
    #tmpl.render(sites=self.sites, jahre=jahre, monate=monate, tage=tage, stunden=stunden, minuten=minuten, sekunden=sekunden)
    return Main.render_pages(self, tmpl, variables)

cherrypy.quickstart(Main(), '/', "conf/cherrypy.conf")

这是'勒罗伊.html'模板：

'基本.html'：

{% block head %}

来自@jwalker的评论解决了我的问题：

You don't need to convert it to a string, just pass the dict to template.render()
