在 Django 视图中，我如何迭代表单字段

Question

在 Django 视图中，我可以遍历表单发布的文件

def stack_register(request):
"""
"""

print(request)
print('type request: ', type(request))


if request.method == 'POST':

    for key in request.FILES.keys():
        print('key: ' + key)


return HttpResponse('received')

我怎样才能对其他表单域做同样的事情？

Answer 1

可以通过在请求中打印元组来获取字段信息，但据我所知，获取值需要实际读取它们或事先了解键。

这就是我得到它的方式：

def stack_register(request):
"""
"""

print(request)
print('type request: ', type(request))


if request.method == 'POST':

    print('')

    for key in request.FILES.keys():
        print('key: ' + key)
        print('file_name: ' + str(request.FILES[key]))


    print('type', type(request.POST.items()))


    for tuple in request.POST.items():  #this was the probelmatic code
        print('tuple: ' + str(tuple))

    #keep syntax for list
    #library = request.POST.getlist('library')
    #print('library: ', library)

    library = request.POST.__getitem__('library')
    print('library: ', library)

    stack = request.POST.__getitem__('stack')
    print('stack: ', stack)

    time = request.POST.__getitem__('time')
    print('time: ', time)

    medium = request.POST.__getitem__('medium')
    print('medium: ', medium)

    comments = request.POST.__getitem__('comments')
    print('comments: ', comments)

    storage = request.POST.__getitem__('storage')
    print('storage: ', storage)   


return HttpResponse('received')

在我的书中，这比学习 Django 表单的狡猾方法和冗长乏味的文档要容易得多，并且提供更多的动手控制。

顺便说一句，对于所有文档爱好者，我认为最好的代码文档是编写良好的简单清晰的代码。
