signup'对象没有'get'属性
我想通过用户输入来存储一个用户名，但我遇到了以下错误：
`AttributeError` at /sign/ `'signup' object has no attribute 'get'`
这是我尝试运行的相关代码：
models.py：
class signup(models.Model):
username = models.CharField(max_length = 50)
def __unicode__ (self):
return self.username
views.py
def sign(request):
username = request.POST['username']
user = signup.objects.create(username=username)
return render(request,'bookstore/signup.html',{'username': username})
bookstore/urls.py
from django.conf.urls import patterns, url
from bookstore import views
urlpatterns = patterns(' ',
url(r'^$',views.home, name = 'home'),
url(r'^sign/$', views.signup,name='signup'),
url(r'^bookshow/$',views.bookshow,name='bookshow'),
url(r'^bookshow/(?P<book_id>\d+)/$',views.bookdetails, name='bookdetails'),
)
signup.html
<html>
<h2>WELCOME TO BOOKSTORE<h2>
<h3>LOGIN TO GET IN LIBRARAY<h3>
{% if errors %}
<ul>
{% for error in errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
<div>
<form action="/sign/" method = "POST">
{% csrf_token %}
<input type="text" username="username" placeholder="USERNAME"/><br />
<input type="submit" value = "signup"/>
</form>
</div>
</html>
我在打开那个页面时遇到的错误

在你的 urls.py 文件里，有一个错误。你把 ^sign/ 这个路径和 signup 这个视图对应起来了，但在你的视图里，你只定义了 sign 这个视图。
你提到的错误是因为在你的 sign 视图中，只处理了 POST 请求，所以没有办法处理 GET 请求。你可以尝试这样修改：
def sign(request):
if request.POST:
username = request.POST['username']
user = signup.objects.create(username=username)
return render(request,'bookstore/signup.html',{'username': username})
return render(request, 'bookstore/login.html')
这里的 bookstore/login.html 可以是一个简单的 HTML 表单，里面有用户名的输入框，提交时会发送到 ^sign/。
