小编Hul*_*ulk的帖子

我正在建立转速请让我知道我哪里出错了,

我的spec文件是rpms.spec,内容是:

Summary: GNU indent
Name: rpms
Version: 1
Release: 1
Source0: %{name}-%{version}.tar.gz
License: GPL
Group: Development/Tools
%description
The GNU indent program reformats C code to any of a variety of
formatting standards, or you can define your own.
%prep
%setup -q
%build
./configure
make
%install
make install
%files
%defattr(-,root,root)
/usr/local/bin/indent
%doc /usr/local/info/indent.info
%doc %attr(0444,root,root) /usr/local/man/man1/indent.1
%doc COPYING AUTHORS README NEWS

我已经将tar文件复制到/ usr/src/redhat/SOURCES /也然后当我执行rpmbuild -ba rpms.spec时出现以下错误

rpmbuild -ba rpms.spec  Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.87218
+ umask 022
+ cd /usr/src/redhat/BUILD

有没有简单的方法在Django中的字段上添加搜索功能？另请告诉我什么是Lucene搜索.

如何为textarea添加"Enter textarea"等水印.

   <textarea rows = "8" cols = "18" border ="0" class="input" style="border: none;" WRAP id="details" name ="details"></textarea>

谢谢..

如何在使用jquery验证textarea时检查null,空格和换行.如果textarea为空并且只有新行或空格应该发出警报

以下代码用于文件上传有什么问题.request.FILES ['file']看起来是空的

楷模:

  from django.db import models 
  from django import forms

  class UploadFileForm(forms.Form):
      title = forms.CharField(max_length=50)
      file  = forms.FileField(label="Your file")

浏览次数:

def index(request):
  if request.method == 'POST':
   a=request.POST
   logging.debug(a["title"])
   logging.debug(a["file"])
   form = UploadFileForm()
   form = UploadFileForm(request.POST, request.FILES)

  handle_uploaded_file(request.FILES['file'])

  if form.is_valid():
     handle_uploaded_file(request.FILES['file'])

     return HttpResponseRedirect('/Files/')
else:
  form = UploadFileForm()
return render_to_response('Files/index.html', {'form': form})


def handle_uploaded_file(f):
 logging.debug("here1")
 #destination = open('some/file/name.txt', 'wb+')
 destination = open('/tmp', 'wb+')
 for chunk in f.chunks():
   destination.write(chunk)
 destination.close()

模板:

      <form name="lang" action="/test/" method="post">
      <table>
     <tr><td>
     <b> {{ form.file.label_tag }}</b>  {{ …

obj = Info(name= sub,question=response_dict["question"])
obj.save()

保存数据后如何更新同一个表的另一个字段

obj.err_flag=1
obj.update()//Will this work

opt=[]
opt=["opt3","opt2","opt7","opt6","opt1"]
for i in range(len(opt)):
     print opt[i]

上面的输出是

opt3,opt2,opt7,opt6,opt1

如何按升序对上面的数组进行排序

      idarr = [1,2,3,4,5]
      for i in  range(len(idarr)):
          upload.objects.filter(idarr[i])

我们不能一次性将idarr传递给查询

如果我有以下数据库字段:id, name, emp_id.

如何在Django中进行查询以name仅使用where子句获取列的值.

谢谢...

在Python中如何实现单属性it.Please以下class.What我基本上是想了解提供了一个例子一类是,如果存在的话类的实例,它应该返回现有实例创建其他的实例那个班

  class Test:
     name
     age

     def getobj(self):
        return (self.name+self.age)

    t= Test()
