我知道有很多这方面的问题,但我需要使用JavaScript来做到这一点.我正在使用Dojo 1.8并拥有数组中的所有属性信息,如下所示:

[["name1", "city_name1", ...]["name2", "city_name2", ...]]

知道如何将其导出到CSV客户端吗？

我第一次开始学习DJango.我有一些python的基本知识,但DJango是我的第一个.我从django的文档页面开始,但是我被困在它要求的地方

python manage.py syncdb

目前我没有任何数据库,所以我认为SQLite附带了django.不确定如何继续？我也下载了virtualenv-1.7.1.2并安装了它,

python virtualenv.py ENV

我正在关注这个视频教程,它要求我使用,

sudo pip install virtualenv

但是当我写上面的代码时,输​​出是,

sudo:pip:找不到命令

帮帮我!!

我在设置空间数据库并将其与GeoDjango同步时遇到了麻烦.我能够根据geodjango文档设置空间数据库并创建一个django应用程序,但是当我运行时

python manage.py sqlall world

我明白这个,

Traceback (most recent call last):

我正在尝试执行此代码，

import osgeo.ogr

def findPoints(geometry, results):
    for i in range(geometry.GetPointCount()):
        x,y,z = geometry.GetPoint(i)
    if results['north'] == None or results['north'][1] < y:
        results['north'] = (x,y)
    if results['south'] == None or results['south'][1] > y:
        results['south'] = (x,y)
    for i in range(geometry.GetGeometryCount()):
        findPoints(geometry.GetGeometryRef(i), results)

shapefile = osgeo.ogr.Open("../../Data/tl_2009_us_state/tl_2009_us_state.shp")
layer = shapefile.GetLayer(0)
feature = layer.GetFeature(53)
geometry = feature.GetGeometryRef()

results = {'north' : None,
           'south' : None}

findPoints(geometry, results)

而且我不断收到此错误，

    findPoints(geometry, results)
