Question

我最近尝试在我的网站上为我的404和500错误实现自定义视图。当debug设置为True时，它运行良好，即，两个自定义视图在调用时都运行良好。但是，只要将Debug设置为False，就只会引发错误500

我已经尝试通过创建URL来调用它们，handler404和handler500自定义视图都可以正常工作。

在该视图中，当它被错误调用时，它应该引发错误404：

def arret(request, id):
    """ Page that show an textuel """
    view = 'search/arret.html'
    arret = get_object_or_404(Arret, id=id)
    arret.compute_bgeref_id()
    query = request.GET.get('q', '')

    form_class =  DecisionForm()
    title = arret.highlight_words(query,input_text=arret.title)

    text = arret.highlight_words(query)
    arret_judges = arret.arret_judges.all()
    decision = arret.decision
    return render(request, view, {'title': title,'text': text, 'date':arret.date, 'tag_string': arret.tag_string, 'tags': arret.get_n_tags(), 'articles': arret.get_n_law_articles(n=15),
                                'bgeref_id': arret.bgeref_ids.all(),"form": form_class, 'id':id, 'query' : query, 'decision': decision,'arret_judges':arret_judges, 'ATF':arret.source=='ATF'
                                })

在这里您可以找到我的404自定义视图：

def handler404(request, template_name="colorlib-error-404-19/index.html"):
    response = render_to_response("colorlib-error-404-19/index.html")
    response.status_code = 404
    return response

在尝试查找不存在的Arret时会引发错误500。这是在终端上写的

Answer 1

可能是您的设置文件没有ALLOWED_HOSTS

Django 1.5引入了出于安全原因而必需的allowed hosts setting。

# Hosts/domain names that are valid for this site; required if DEBUG is False
# See https://docs.djangoproject.com/en/dev/ref/settings/#allowed-hosts
ALLOWED_HOSTS = []

在此处添加主机，例如['www.example.com']或['*']进行快速测试，但不要使用['*']进行生产。

或者，可能是您尝试在不运行collectstatic的情况下访问某些静态文件。在大多数情况下，在视图中加载响应后，应该为404，但是如果您在代码中访问它们，则可能为500。

当“调试”设置为“假”
