Question

我有一个视图，它根据传入的技能从数据库中提取多个用户。它几乎按照需要工作，除非它返回多个用户，它只传回最近获取的用户。如何聚合提取的用户以传递回模板。我已经尝试将它们作为列表传回，但它们没有出现。

这是我的代码：

form = FilterFreelancerForm(request.POST)
        filtered_skills = set((request.POST.getlist('skills_select')))

        match_fl = Freelancer.object.annotate(c=Count('skills')).filter(c=len(filtered_skills))
        candidate_freelancers = None

        for skill in filtered_skills:
            candidate_freelancers = match_fl.filter(skills=skill)

        freelancers = None

        for freelancer in candidate_freelancers:
            freelancers = User.objects.filter(freelancer=freelancer.id)

    return render(request, 'freelancestudent/browsefreelancers.html', {'freelancers': freelancers,
                                                                       'filter_form': form})

我之前有这个：

    freelancers = []

    for freelancer in candidate_freelancers:
        freelancers.append(User.objects.filter(freelancer=freelancer.id))

不向模板返回任何内容。

Answer 1

而不是：

for freelancer in candidate_freelancers:
    freelancers = User.objects.filter(freelancer=freelancer.id)

尝试：

freelancers = User.objects.filter(freelancer__in=[freelancer.id for freelancer in candidate_freelancers])

出：

[<User: user1>, <User: user2>]

返回多个提取的用户
