Django：以10为底的int（）的无效文字 [英] Django: invalid literal for int() with base 10

问题描述

我是Django的新手，他试图将作者的名字传递到视图中，并根据作者的名字过滤掉引用对象。以下是代码：

I am new to Django and trying to pass an author's name to a view and filter out quote objects based on the author's name. here are the codes:

models.py

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 })

但是当我尝试获取 http://127.0.0.1:8000/quotes/you/
（您是已经创建的测试作者对象）

However I get this error when I try to get http://127.0.0.1:8000/quotes/you/ ('you' is a test author object, already created)

I appreciate your help to resolve this.

推荐答案

您要搜索作者的 author_name 字段，而不是

You want to search on the author's author_name field, not the id.

Quote.objects.filter(author__author_name=name)

在当前搜索中， author__exact ，Django期望 name 是作者的ID，因此会出现错误，因为 you 不是整数。

With your current search, author__exact, Django expects name to be the id of the author, so gives an error because you is not an integer.
