Question

对于非常相似的视图和模板，我有3个视图。

我的代码变得重复，似乎没有遵循Django DRY 方法。

Views.py

@login_required
def registrations_check1_detail(request, registration_pk):

    registration = get_object_or_404(Registration, pk=registration_pk)

    costumer_profile_form = forms.CostumerProfileForm()

    # THIS CONTEXT IS REPEATED ACROSS  MANY OF MY VIEWS
    request_context = {
        'registration': registration,
        'status': Registration.STATUS_CHOICES,
        'costumer_profile_form': costumer_profile_form,
        'duration_form':  pf.DurationForm(),
        'REG_DURATION_CHOICES'  : Duration.REG_DURATION_CHOICES,
        'EXT_DURATION_CHOICES'  : Duration.EXT_DURATION_CHOICES,
        'is_editable': editable_fields_perm(request.user, registration)
    }

    return render(request, 'profiles/registrations_check1_detail.html', request_context)

@login_required
def finance_review_detail(request, registration_pk):

    costumer_profile_form = forms.CostumerProfileForm()

    registration = get_object_or_404(Registration, pk=registration_pk)

    request_context = {
        'registration': registration,
        'costumer_profile_form': costumer_profile_form,
        'duration_form':  pf.DurationForm(),
        'REG_DURATION_CHOICES'  : Duration.REG_DURATION_CHOICES,
        'EXT_DURATION_CHOICES'  : Duration.EXT_DURATION_CHOICES,
        'is_editable': editable_fields_perm(request.user, registration)
    }

    return render(request, 'profiles/finance_review_detail.html', request_context)

处理此问题的正确方法是什么？

修改

按照商王的建议，这就是它现在的样子：

@login_required
def registration_detail(request, registration_pk):

    request_context = _registration_context(registration_pk, request.user)

    return render(request, 'profiles/registration_detail.html', request_context)

Answer 1

这是正常的，但解决方案非常简单，您可以将它们提取到函数中，并且只传递生成结果所需的参数，例如costumer_profile_form，registration。然后你调用函数，应该是它。

在Django中分享视图之间的上下文？
