如何让我的视图更好地拯救 Django

大家对这篇文章感到抱歉，但我需要有关我的应用程序的帮助，我需要优化我的视图。我有 5 个模型，我该怎么做？

def save(request):  

    # get the request.POST in content
    if request.POST:
        content = request.POST
        dicionario = {}
        # create a dict to get the values in content 
        for key,value in content.items():
            # get my fk  Course.objects
            if key == 'curso' :
                busca_curso  = Curso.objects.get(id=value)
                dicionario.update({key:busca_curso})
            else:
                dicionario.update({key:value})
        #create the new teacher
        Professor.objects.create(**dicionario)

我的问题是？

1 - 我如何以通用方式执行此功能？我可以在 %s 中传递一个变量来创建和得到？喜欢这样吗？

foo = "Teacher" , bar = "Course" 

def save(request, bar, foo):
    if request post:
    ...
    if key == 'course' :
       get_course = (%s.objects.get=id=value) %bar
       ...
    (%s.objects.create(**dict)) %foo ???

在我看来，我尝试这样做，但不起作用=/，有人可以帮助我完成这项工作吗？谢谢

您应该使用 ModelForms，而不是手动执行这一切。这样您就可以简单地创建一个表单，该表单将在调用 save() 时自动创建您的对象。

例子：

class ProfessorForm(ModelForm):
    class Meta:
        model = Professor

def save(request):
    if request.method == 'POST':
        form = ProfessorForm(request.POST)
        if form.is_valid():
            form.save()

Instead of doing this all manually you should use ModelForms. That way you can simply create a form that will automatically create your object upon calling save().

Example:

class ProfessorForm(ModelForm):
    class Meta:
        model = Professor

def save(request):
    if request.method == 'POST':
        form = ProfessorForm(request.POST)
        if form.is_valid():
            form.save()
