我希望在提交表单之前将所有表单值更改为大写.
到目前为止,我有这个,但它不起作用.
$('#id-submit').click(function () {
var allInputs = $(":input");
$(allInputs).value.toUpperCase();
alert(allInputs);
});
我有一个weblogic 10.3.5 Web应用程序,每次刷新页面时JSESSIONID都会更改.这导致我的应用程序的上下文丢失.
这只发生在Chrome和Safari上,Firefox和IE工作正常.
我已经尝试过添加一个favicon并创建一个context.xml但这些解决方案都没有用.
知道会发生什么事吗？

如何比较django查询中的两个字段？
基本上我想要的是将任务延迟和on_time分成两个查询.
当今天和请求日期之间的差异超出容忍天数时,任务会延迟.
现在我有这个:
def dayssince(value):
if value is None:
return '0'
#"Returns number of days between today and value."
today = datetime.date.today()
diff = today - value
if diff.days > 1:
return '%s' % diff.days
elif diff.days == 1:
return '1'
elif diff.days == 0:
return '0'
else:
# Date is in the future; return formatted date.
return value.strftime("%B %d, %Y")
on_time = process.(Department__Tolerance__gte=dayssince(F('Request_date'))).annotate(Counter=Count('Client'))
delayed = process.(Department__Tolerance__lte=dayssince(F('Request_date'))).annotate(Counter=Count('Client'))
但我得到属性错误: 'ExpressionNode'对象没有属性'days'
我的 MessageFolder 模型中有一个信号可以正常工作，但是在某些特殊情况下我不希望发生 post_save 信号操作。在这种情况下如何停用它？
我已经尝试了以下，但它不是 workign。
视图.py
signals.post_save.disconnect(receiver=MessageFolder,sender=Message)
email_message = EmailMessage(
subject,
message,
my_username,
[recipent,],
[], # ['bcc@example.com'],
headers = {'Reply-To': 'gusreyes01@example.com'}
)
signals.post_save.connect(MessageFolder,MessageFolder.assign_message_folder)
# Save it
my_mailbox.record_outgoing_message(
email_message.message()
)
模型.py
class MessageFolder(models.Model):
folder = models.ForeignKey(Folder, null = True, blank = True)
message = models.ForeignKey(Message, null = True, blank = True)
@receiver((post_save), sender=Message, dispatch_uid="assign_message_folder")
def assign_message_folder(sender, instance, created, **kwargs):
if not created:
return
else:
# generate MessageFolder && UserFolder
if(instance.outgoing):
message_folder = MessageFolder(None, 2, instance.pk)
else:
message_folder = MessageFolder(None, …如何确保完整的行在 AngularJS 中是唯一的？
<tr ng-repeat="service in services" >
我知道这里讨论的现有独特过滤器。然而，这仅解释了如何对一列进行唯一过滤。我想在多个列上执行此操作。例如：
<tr ng-repeat="service in services | unique:['category','type','quantity'] >
在初始化视图时,如何只运行一次orderBy过滤器？我不希望我的列表在运行时重新排序.
<li ng-repeat="service in quote.services | orderBy:'index'" ></li>
我有两个外部库（jQuery X-editable 和 FineUploader）需要的 javascript 代码，我需要我的上下文变量。因此，我不能为此代码使用外部 js。

查询集是通过 cursor.execute() 获得的，因此可能需要一个假模型。
基本上我只想利用 Django 管理列表提供的分页和过滤功能。
这是我的代码的相关部分
模型.py
class Query(object):
def __init__(self, sql):
self.sql = sql
def execute_query(self):
cursor = connection.cursor()
start_time = time()
try:
cursor.execute(self.sql)
except DatabaseError as e:
cursor.close()
raise e
return cursor, ((time() - start_time) * 1000)
管理文件
class QueryAdmin(admin.ModelAdmin):
....
admin.site.register(Query, QueryAdmin)
我正在使用以下django视图获取许多不同的视图,有没有办法重定向到调用它的视图？
def delete_image(request,id,image_id):
ImagenAvaluo.objects.filter(image_id=image_id).delete()
return calling_view(request,id)
我想向拥有顾问权限的所有用户发送电子邮件:perms.profiles.consultant_permission
我的代码如下:
model.py
class Profile(models.Model):

)
view.py
consultant_msg_html = render_to_string('email/consultant_review_email.html', context)
send_mail("Register sent to review",
consultant_msg_html,
registration.consultant.email,
[registration.consultant.email,],
html_message=consultant_msg_html,
fail_silently = False)
我怎样才能做到这一点？
如何找出日期范围内的小时数？我正在计算和打印两个给定日期之间的日期.
from datetime import timedelta as td, datetime
d1 = datetime.strptime(start_date, '%Y-%m-%d')
d2 = datetime.strptime(end_date, '%Y-%m-%d')
def get_delta(d1, d2):
delta = d2 - d1
return delta
delta = get_delta(d1,d2)
for i in range(delta.days + 1):
print d1 + td(days=i)

我已经设法使用modelformset_factory创建我需要的表单.
avaluos = Avaluo.objects.filter(Estatus__contains='CONCLUIDO',Factura__isnull=True)
FacturaFormset = modelformset_factory(Avaluo,form=FacturaForm,extra=0)
目前,这为每个找到的行生成以下HTML:
<form id="id-FacturaForm" class="blueForms" method="post">[..]</form>
<form id="id-FacturaForm" class="blueForms" method="post">[..]</form>
<form id="id-FacturaForm" class="blueForms" method="post">[..]</form>
我想使用单个提交按钮提交所有表单.
有任何想法吗？
我最终使用了django-crispy-forms,它允许我为每一行输入输入,然后我只需手动添加表单并提交.
self.helper.form_tag = False
{{example_formset.management_form }}
{% for a,b in olist %}
{{ b.id }}
<tr>
<td style="width:10px;"> {% crispy b %} </td>
<td> {{a.id}} </td>
</tr>
{% endfor %}
什么是使用Django 1.5实现套接字的最佳替代方案？
我愿意在我的Django网站上实现一个聊天室和通知.
我已经回顾了Socket.io和node.js,但想知道每个的优点/缺点.
