嗨，我已经搜索了这个，找到了类似的主题，但没有一个给我一个答案，似乎有帮助。或者我可能搜索了错误的术语。
现在我想知道，你是否可以选择性地合并一个“返回渲染”的上下文。...”命令。由于Django传播了一种“不要重复你自己”的哲学，我想修改下面的代码来缩短它（几个if子句与角色权限有关。...）：

def show(request):

    now_day = datetime.date.today()
    current_user = request.user 

    if request.method == 'GET':

        if view_self(current_user) == True and more_rights(current_user) == False:
            if Employees.objects.filter(employee_number=current_user).exists():

                context = {'names': Employees.objects.filter(employee_number=current_user)}
            else:
                context = {'info': "Für sie existiert (noch) kein Datensatz in dieser Datenbank"}  
        else: 
            context = {'names': Employees.objects.all().order_by('last_name').values()}

        return render(request, 'show.html', context)

    else:
        if view_self(current_user) == True and more_rights(current_user) == False:

            if request.POST['id'] == 'Mitarbeiter auswählen...':
                context = {
                    'names': Employees.objects.filter(employee_number=current_user),
                    'info': "Bitte treffen Sie zuerst eine Auswahl"
                }
            else:
                employee = request.POST['id']
                context = {
                    'names': Employees.objects.filter(employee_number=current_user),
                    'entries': Employees.objects.filter(id=request.POST['id']),
                    'work_conditions': Employment.objects.filter(employee_id=request.POST['id']),
                    'functions': Functions.objects.filter(employee__functions=request.POST['id']).order_by('function'),
                    'fieldsoa': FieldsOfActivity.objects.filter(employee__fieldsofactivity=request.POST['id']).order_by('field_of_activity'),
                    'missions': Foreign_Missions.objects.filter(employee_id=request.POST['id']).order_by('-begin'),
                    'examinations': Examinations.objects.filter(employee_id=request.POST['id']).order_by('-date'),
                    'total_duration_days': Foreign_Missions.objects.total_duration_days(employee),
                    'today': now_day,
                    'special_header': "Datensätze anzeigen"
                }

        elif request.POST['id'] == 'Mitarbeiter auswählen...':
            context = {
            'names': Employees.objects.all().order_by('last_name').values(),
            'info': "Bitte treffen Sie zuerst eine Auswahl"
            }
    
        elif 'id' in request.POST:
            employee = request.POST['id']             #Employees.objects.get(pk=id)
            context = {
            'names': Employees.objects.all().order_by('last_name').values(),
            'entries': Employees.objects.filter(id=request.POST['id']),
            'work_conditions': Employment.objects.filter(employee_id=request.POST['id']),
            'functions': Functions.objects.filter(employee__functions=request.POST['id']).order_by('function'),
            'fieldsoa': FieldsOfActivity.objects.filter(employee__fieldsofactivity=request.POST['id']).order_by('field_of_activity'),
            'missions': Foreign_Missions.objects.filter(employee_id=request.POST['id']).order_by('-begin'),
            'examinations': Examinations.objects.filter(employee_id=request.POST['id']).order_by('-date'),
            'total_duration_days': Foreign_Missions.objects.total_duration_days(employee),
            'today': now_day,
            'special_header': "Datensätze anzeigen"
            }

        return render(request, 'show.html', context)

所以我的问题是我能不能以一种实用的方式“分割”上下文行，把每个对应的if子句中显示的部分放在靠近return render命令的位置，这样我就不必重复这些行了？
更新2023-04-28：尝试（使用另一个模块，更短的代码，更容易阅读）空上下文和逐步填充的方法。不会在这里工作：

def delete(request):

context = {}
context['names'] = Employees.objects.all().order_by('last_name').values(),

if request.method == 'GET':
    context = {
        # 'names': Employees.objects.all().order_by('last_name').values(),
        'special_header': "Datensätze löschen",
    }
    
# Wenn der Button ohne Auswahl gedrückt wird
elif 'id' in request.POST and request.POST['id'] == 'Mitarbeiter löschen...':
    context = {
        # 'names': Employees.objects.all().order_by('last_name').values(),
        'info': "Bitte treffen Sie zuerst eine Auswahl"
    }

else:
    id = request.POST['id']
    lastname = Employees.objects.get(id=id).last_name.upper()
    firstname = Employees.objects.get(id=id).first_name
    trash = Employees.objects.filter(id=id)
    # trash.delete()

    context = {
        # 'names': Employees.objects.all().order_by('last_name').values(),
        'success': "Datensatz für " + lastname + ", " + firstname + " wurde gelöscht"
    }

return render(request, 'delete.html', context)

在代码中留下了注解部分，以澄清我想做的事情
