所以，我的问题是我有一个detailview，它显示了我数据库中的特定帖子 . 然后，我使用get_context_data然后从不同的模型中获取db值;但是，它在我的模板中输出一些奇怪的东西 .
我可以在模板中更改哪些内容，以便从其他模型中列出每个正确的数据库值？
models.py
class Projects(models.Model):
user = models.ForeignKey(User)
slug = models.SlugField()
project_title = models.CharField(max_length=30)
project_shortdesc = models.CharField(max_length=248)
project_desc = models.TextField()
def save(self):
super(Projects, self).save()
date = datetime.date.today()
self.slug = '%i%i%i%s' % (
date.year, date.month, date.day, slugify(self.project_title)
)
super(Projects, self).save()
class ProjectsToDo(models.Model):
project_tododate = models.DateField()
project_tododesc = models.TextField(max_length = 500)
project_id = models.ManyToManyField(Projects)
views.py
class ProjectDetail(generic.DetailView):
model = Projects
context_object_name = 'indprojects'
template_name = 'projectpage.html'
def get_context_data(self, *args, **kwargs):
context = super(ProjectDetail, self).get_context_data(*args, **kwargs)
context['todolist'] = ProjectsToDo.objects.order_by('project_tododate')
context['todoform'] = ProjectToDoForm()
context['form'] = ProjectForm(instance=Projects.objects.get(slug=self.kwargs['slug']))
return context
def get_queryset(self):
return Projects.objects.filter(user=self.request.user)
@method_decorator(login_required)
def dispatch(self, request, *args, **kwargs):
return super(ProjectDetail, self).dispatch(request, *args, **kwargs)
模板
{{todolist}}
这个来自模板，输出： [<ProjectsToDo: ProjectsToDo object>, <ProjectsToDo: ProjectsToDo object>] 我试过 {{todolist.project_tododesc}} ，两者都没有输出数据 . 我不确定如何解决这个问题，任何帮助都将不胜感激 .

我认为问题是如果在类
ProjectsToDo中使用Python 3（或Python 2.x中的__unicode__()），则没有定义__str__()方法 .当您尝试打印模型实例时，会发生什么是Django会查看
__str__()以决定要显示的内容 .See here for more about str()
