Django：int()与base 10无效的文字

我是Django的新手,试图将作者的名字传递给一个视图,并根据作者的姓名筛选出报价对象.以下是代码：

models.py

class Author(models.Model):
    author_name = models.CharField(max_length=50, default='unknown')
    author_info = models.TextField(max_length=1000)


class Quote(models.Model):
    author = models.ForeignKey(Author)
    quote = models.TextField(max_length=500)
    category= models.ForeignKey(Category)
    pub_date = models.DateTimeField('date published')

urls.py：

url(r'^quotes/(?P<name>\w+)/$', 'quotes.views.quotesbyauthor'),

views.py

def quotesbyauthor(request, name):
    aquotelist = Quote.objects.filter(author__exact = name)
    return render_to_response(quotes_by_author.html, {'aquotelist': aquotelist })

但是当我尝试获得 http://127.0.0.1:8000/quotes/you/ 时,我收到这个错误

(‘你’是一个测试作者对象,已经创建)

感谢您的帮助解决这个问题.

你想搜索作者的author_name字段,而不是id.

Quote.objects.filter(author__author_name=name)

使用你当前的搜索,author_exact,Django希望name作为作者的id,所以给出一个错误,因为你不是一个整数.
