我试图在Django中进行X-Editable内联编辑模型.我只是想尝试更改模型实例的属性(在本例中,是数据集对象的名称).
我不确定如何编写视图,以便正确捕获ajax请求中的信息:
POST /datasets/9/update_name/
{
pk: 3 //primary key (record id)
value: 'The Updated Name' //new value
}
然后将新名称保存到数据集对象.
urls.py
# ex: /datasets/3/update_name
url(r'^(?P<pk>\d+)/update_name/$', update_name ,
name='update_name'),
detail.html
<h1 class="page-title center">
<a href="#" id="datasetName">{{ dataset.name }}</a>
</h1>
<script>
$('#datasetName').editable({
type: 'text',
pk: {{ dataset.pk }},
url: '{% url 'datasets:update_name' dataset.pk %}',
title: 'Edit dataset name'
params: { csrf: '{% csrf_token %}'} # // This isn't working
});
</script>
views.py
def update_name(request, dataset_id):
# ... Update Dataset object ... …我有一个托管在Github和PyPI上的Python项目.
在Github上:https://github.com/sloria/TextBlob/blob/master/README.rst
在PyPi上:https://pypi.python.org/pypi/textblob
我的README.rst似乎没有在PyPI上正确格式化,但它在Github上看起来很好.
我已经读过这个了,但是我没有任何页内链接,所以这不是问题所在.
我正在尝试在我的Mac OS X 10.7.3(Lion)上安装Orange,并且在使用pip或从源代码构建时我一直收到错误.首先,我收到的错误是:
error: command 'gcc-4.0' failed with exit status 1
我有Xcode 4,它与gcc 4.2.1捆绑在一起.所以我安装了64位/ 32位Python 2.7.3,它内置了gcc 4.2.我还尝试使用以下方法覆盖编译器选项:
export CC=gcc-4.2
但这产生了一个不同的错误:
gcc-4.2 not found, using clang instead
...
error: command 'clang' failed with exit status 1
这是完整的日志:

3. …当我在if-block中调用一个方法时,我得到一个TypeError,但是当在if块之外调用它时,该方法会运行find:
randenzyme()从一个叫做酶的词典中随机选择一个键:
def randenzyme(self):
an_enzyme = choice(self.enzymes.keys())
它运行正常:
x = TCA()
x.randenzyme()
但是"TypeError:'str'对象不可调用"引发:
x = TCA()
user_input = raw_input('> ')
if user_input == "1":
x.randenzyme()
在if块中调用方法时发生了什么？
