问题 1
raise ImproperlyConfigured("settings.DATABASES is improperly configured. " django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.
确认DATABASES节点中配置是否正常,如：
检查是否有多个settings.py文件.如果是逐个检查对应节点.
问题 2
ImportError： No module named XXX
确认这里到底该不该用include
问题 3
Warning:
Incorrect string value: '\xE5\xBC\xA0\xE4\xB8\x89' for column 'username' at row 1
因为字符乱码的问题造成的。
需要mysql支持中文，更改mysql的字符集.
方式一： 在创建时指定默认如：
mysql> create database test default charset=utf8;
然后再同步生成sql:
>>> python manage.py syncdb
方式二：
mysql > ALTER DATABASE bugzero_db CHARACTER SET utf-8;
这种方式只有在数据库中没有table的情况下才work
方式三：
mysql> SET character_set_client = utf8 ;
mysql> SET character_set_connection = utf8 ;
mysql> SET character_set_database = utf8 ;
mysql> SET character_set_results = utf8 ;
mysql> SET character_set_server = utf8 ;
mysql> SET collation_connection = utf8 ;
mysql> SET collation_database = utf8 ;
mysql> SET collation_server = utf8 ;
但是这种方法在发送查询或进行与mysql交互时最好还是要加：
SET NAMES 'utf8'；
相当于：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;
不然还是不正常工作.
问题 4
Forbidden (403)CSRF verification failed. Request aborted.CSRF token missing or incorrect.
In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure:Your browser is accepting cookies.
The view function uses RequestContext for the template, instead of Context.In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.You're seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.You can customize this page using the CSRF_FAILURE_VIEW setting.
方法1)：开发过程中暂时注释settings.py中 'django.middleware.csrf.CsrfViewMiddleware'办法2):
在django1.4里，就必须按照提示的步骤来：
1，在view里面，强制使用RequestContext 代替Context。示例如下：
from django.template import RequestContext
视图返回要这样：
return render_to_response('index.html', {
'param1': 'aaa', 'param2': 'bbb', }, context_instance=RequestContext(request) # here！)
2，在模板的form体里面，加入 {% csrf_token %}，示例如下：
<form action="login.html" method="post" >
{% csrf_token %}……
</form>
最后检查一下中间件里'django.middleware.csrf.CsrfViewMiddleware',是否正常开放。默认是直接开着的。
-------------------
注意，在Django 1.2(含1.2) 之前，解决办法是
在settings的中间件设置里MIDDLEWARE_CLASSES加入：
'django.middleware.csrf.CsrfResponseMiddleware',
此解决方法来自：
方法3)
如果用jQuery来处理ajax的话，Django直接送了一段解决问题的代码。把它放在一个独立的js文件中，在html页面中都引入即可。注意这个js文件必须在jquery的js文件引入之后，再引入即可
$(document).ajaxSend(function(event, xhr, settings) { function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } function sameOrigin(url) { // url could be relative or scheme relative or absolute var host = document.location.host; // host + port var protocol = document.location.protocol; var sr_origin = '//' + host; var origin = protocol + sr_origin; // Allow absolute or scheme relative URLs to same origin return (url == origin || url.slice(0, origin.length + 1) == origin + '/') || (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') || // or any other URL that isn't scheme relative or absolute i.e relative. !(/^(\/\/|http:|https:).*/.test(url)); } function safeMethod(method) { return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } if (!safeMethod(settings.type) && sameOrigin(settings.url)) { xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken')); } }); 方法4)：
在处理post数据的view前加@csrf_exempt装饰符
[python] view from django.views.decorators.csrf import csrf_exempt@csrf_exemptdef profile_delte(request): del_file=request.POST.get("delete_file",'') 问题 5
mysqldump执行时Got error: 1045: Access denied for user 'root'@'localhost' (using password: YES) when trying to connect
去掉-p以及参数，加 -h host
这个host是写ip,或127.0.0.1如：
mysqldump -h 127.0.0.1 -u root database_name> /usr/mysql.sql
问题 6
MediaDefiningClass object is not iterable
注意django 的注册方式
第一个参数是model，第二个参数是Model的管理类,如：
class AuthorAdmin(admin.ModelAdmin): passadmin.site.register(Author, AuthorAdmin)
问题 7
SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data
仔细验证数据格式是否是完整正确，如：
JSON.parse({"name":"v"}) 错误
JSON.parse('{"name":"v"}') 正确
问题 8
encoding问题,在给字典dict赋值时，一直报错类似：
['\xd6\xd0\xce\xc4']
对于中文在设置这个key时要记得加u
比如：
k = '中文'
dict[u''+k] = ".........."
就正常work了.
