TemplateDoesNotExistHeroku在查找我的html文件时收到错误.这些文件都在开发服务器上同步.该TEMPLATE_DIRS设置设置为:
TEMPLATE_DIRS = ['/Users/jonathanschen/Python/projects/skeleton/myportfolio/templates',]
但是当我尝试加载页面时,我发现了以下错误:我认为这里有一些非常基本的东西.
TemplateDoesNotExist at /
index.html
Request Method: GET
Request URL: http://morning-coast-2859.herokuapp.com/
Django Version: 1.4.1
Exception Type: TemplateDoesNotExist
Exception Value:
index.html
Exception Location: /app/.heroku/venv/lib/python2.7/site-packages/django/template/loader.py in find_template, line 138
Template-loader postmortem
Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
/Users/jonathanschen/Python/projects/skeleton/myportfolio/templates/index.html (File does not exist)
Using loader django.template.loaders.app_directories.Loader:
/app/.heroku/venv/lib/python2.7/site-packages/django/contrib/auth/templates/index.html (File does not exist)
/app/.heroku/venv/lib/python2.7/site-packages/django/contrib/admin/templates/index.html (File does not exist)
我将这个字符串列表转换为浮点列表时遇到了一些困难.我尝试了这两种方式,每种都返回了不同的错误.
import csv
import math
unemp_reader = csv.reader(open('unemp.csv', 'rU'))
unemp_lines = list(unemp_reader)
for rows in unemp_lines: #tried this way, but error tells me indices must be integers
i = 1
for i in rows:
a = map(float, unemp_lines[i])
float_list.append(a)
print float_list
for row in unemp_lines: #tried this way but the list returned is empty
y = row[1].split(",")[1:-1]
float_list = [float(i) for i in y if i]
print float_list
您好,感谢您的帮助.我刚刚开始学习Python和Django,并且一直在尝试在djangoproject.com中设置教程.我一直在尝试设置服务器,但不断收到此错误:
