这是观点:

def showProject(request, project_slug):
project = Project.objects.get(slug=project_slug)
tickets = Ticket.objects.filter(project=project)
payload = { 'project':project, 'tickets':tickets }
return render(request, 'project/project.html', payload)

这是错误:

Traceback:

  111.                         response = callback(request, *callback_args, **callback_kwargs)

Exception Type: DoesNotExist at /project/ticket/

Exception Value: Project matching query does not exist.

有关预期内容的更详细说明:我有一个侧栏,列出所有打开的"门票".当我点击其中一张票时,它应该打开它.相反,当我尝试打开它时,我收到了这个错误.怎么了？这是模型类:

class Project(models.Model):
    """simple project for tracking purposes"""
    name = models.CharField(max_length = …

我有一个奇怪的问题...这段代码工作正常,直到我处理其他一些观点,现在,它不起作用.

这是我的观点:

def showTickets(request, project_slug):
    project = Project.objects.get(slug=project_slug)
    tickets = Ticket.objects.get(project=project)
    payload = { 'project':project, 'tickets':tickets}
    return render(request, 'project/tickets.html', payload)

{% extends 'project/base.html' %}

{% block title %}Tickets: {{project.name}}{% endblock %}
