这个报错是正常的，因为之前FOR 循环，有些字段为空的,通过检查，发现是之前检查表空间的语句返回值为空，所以导致这个报错。修改检查表空间的语句，方可进行
另外expection 也可以由以下
from
# error_msg = "%s 数据库连接失败：%s %s" % (tags, unicode(str(e), errors='ignore'))
to
error_msg = "%s 目标主机连接失败：%s " % (tags, str(e))
my_log.logger.info('%s：debug' % tags)
改成
except:
info=sys.exc_info()
print info[0],":",info[1]

档就绪事件
您也许已经注意到在我们的实例中的所有 jQuery 函数位于一个 document ready 函数中：
$(document).ready(function(){
// jQuery methods go here...
});
这是为了防止文档在完全加载（就绪）之前运行 jQuery 代码。
如果在文档没有完全加载之前就运行函数，操作可能失败。下面是两个具体的例子：
试图隐藏一个不存在的元素
获得未完全加载的图像的大小
提示：简洁写法（与以上写法效果相同）:
$(function(){
// jQuery methods go here...
});
HTTP 请求：GET vs. POST
两种在客户端和服务器端进行请求-响应的常用方法是：GET 和 POST。
GET - 从指定的资源请求数据
POST - 向指定的资源提交要处理的数据
GET 基本上用于从服务器获得（取回）数据。注释：GET 方法可能返回缓存数据。
POST 也可用于从服务器获取数据。不过，POST 方法不会缓存数据，并且常用于连同请求一起发送数据。
如需学习更多有关 GET 和 POST 以及两方法差异的知识，请阅读我们的 HTTP 方法 - GET 对比 POST。

jQuery.get()

http://api.jquery.com/jquery.each/ （重要）
jQuery.get()
Description: Load data from the server using a HTTP GET request.
http://www.w3school.com.cn/jquery/ajax_get.asp
使用 AJAX 的 GET 请求来改变 div 元素的文本：
$("button").click(function(){
$.get("demo_ajax_load.txt", function(result){
$("div").html(result);
});
});
https://blog.csdn.net/aoerqileng/article/details/79131736
return HttpResponse
这种方式ajax在接收到后一直执行error部分代码，其实返回的数据是没有问题的。
后来换了
return HttpResponse(json.dumps({“serverList”:serverList}), content_type=”application/json”)
这种形式就没有问题了
在返回json对象，动态在原页面加载显示的时候，还是使用httpresponse吧。你直接返回数据给html，不同过ajax请求这种的可以用render
return render
这里是这样：后台传递一些数据给html，直接渲染在网页上，不会有什么复杂的数据处理（如果前台要处理数据，那么就传数据给JS处理）
views.py 的函数和 urls 函数匹配
views的函数定义的网页与template的网页 匹配
views的变量传递到template 网页
template 网页的jquery 的值通过 views 的函数处理
$(selector).html()
输出到HTML
json可以在网页中输出
import json
技能提升：getJSON中的写的对应网址，用 urls.py 中的 name 来获取是一个更好的方法!
标签：{% url 'name' %}
【已解决】Object of type 'range' is not JSON serializable
所以问题应该就出现在Python的版本上,我用的是Python3.6.2
所以Python3.X和2.X的range()用法是不一样的
def ajax_list(request):
a = list(range(100))
return JsonResponse(a, safe=False)

迁移一个项目的SQLLIT数据库到另一台服务器的数据库
1.
默认配置下，Django 的模板系统会自动找到app下面的templates文件夹中的模板文件。
Django 模板查找机制： Django 查找模板的过程是在每个 app 的 templates 文件夹中找（而不只是当前 app 中的代码只在当前的 app 的 templates 文件夹中找）。各个 app 的 templates 形成一个文件夹列表，Django 遍历这个列表，一个个文件夹进行查找，当在某一个文件夹找到的时候就停止，所有的都遍历完了还找不到指定的模板的时候就是 Template Not Found （过程类似于Python找包）。这样设计有利当然也有弊，有利是的地方是一个app可以用另一个app的模板文件，弊是有可能会找错了。所以我们使用的时候在 templates 中建立一个 app 同名的文件夹，这样就好了。
Django 找不到模版报错" django.template.exceptions.TemplateDoesNotExist: index.html"
(https://www.cnblogs.com/alan-babyblog/p/5828026.html)
解决办法：在setting.py的TEMPLATES‘DIRS'[]加入模版路径
'BACKEND': 'django.template.backends.django.DjangoTemplates',

1、下载sqlite3【http://www.sqlite.org/sqlite-shell-win32-x86-3071401.zip】
2、将sqlite3.exe文件放入（C:\Windwos\System32）中
3、C:\Users\Administrator\PycharmProjects\untitled3>python manage.py dbshell
4. ADD sqlite3.exe on the directory that de manage.py
http://www.runoob.com/sqlite/sqlite-select.html
sqlite> SELECT tbl_name FROM sqlite_master WHERE type = 'table';
sqlite> SELECT sql FROM sqlite_master WHERE type = 'table' AND tbl_name = 'exam2014_biodrug';
sqlite>
CREATE TABLE district_info(
ID INT NOT NULL,
P_ID TEXT NOT NULL,
NAME VARCHAR(50)
)
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (11, 0,'湖南');
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (12, 0,'广东');
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (13, 0,'北京');
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (14, 0,'天津');
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (15, 0,'河北');
INSERT INTO district_info (ID,P_ID,NAME)
VALUES (16, 0,'山西');
3.
python manage.py dbshell
python manage.py makemigrations
python manage.py migrate
4
$.ajaxSetup({
data: {csrfmiddlewaretoken: '{{ csrf_token }}' },
});
这样之后，就可以像原来一样的使用 jQuery.ajax() 和 jQuery.post()了
5.
views.py
def home(request):
TutorialList = ["HTML", "CSS", "jQuery", "Python", "Django"]
return render(request, 'home.html', {'TutorialList': TutorialList})
在视图中我们传递了一个List到模板 home.html，在模板中这样使用它：
home.html
教程列表：
{% for i in TutorialList %}
{{ i }}
{% endfor %}

错误信息如下:
RuntimeError at /picload
You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set.
Django can't redirect to the slash URL while maintaining POST data. Change your form to point
to 127.0.0.1:8000/picload/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
表单字段action以'/'结尾，(action="/picsave/)，尝试修改settings文件，设置了APPEND_SLASH = False属性，
bug仍存在。最后将应用的urls中对应的路径末去掉'/'，(r'^picsave/$'，去掉表达式中的'/')，bug修复。
PS：仔细了解APP中urls路径配置详细规则

修改下拉框为可选项（直接从数据库获得信息）。

Unexpected data type " Exception: Unexpected data type datetime.timedelta "

精通 Oracle+Python，第 2 部分：处理时间和日期
日期操作涉及的另一数据类型为 INTERVAL，它表示一段时间。在编写本文时，Python 不支持将 INTERVAL 数据类型作为查询的一部分返回。唯一的方法是SQL使用 EXTRACT 从时间间隔中提取出所需的信息。尽管如此，包含返回 TIMESTAMP 类型的时间间隔的查询仍然运转良好。

8 python 如何调用变量
diag_trace_dir = diag_trace[0][0]
cmd = 'tail -300 %s/alert_*.log |grep -A 3 ORA-' %diag_trace_dir
9.Python manage.py runserver 的根目录是在manage.py 这个目录下执行，这个跟单个独立测试的Py 目录不一样
py文件在server 段被调用显示为根目录
print os.getcwd()
file_path = os.getcwd() + '\check_result' + '\\'
py文件在单个文件执行显示为当前目录。
print os.getcwd()
file_path = os.path.abspath(os.path.join(os.path.dirname("__file__"),os.path.pardir)) + '\check_result' + '\\'
