Question

我如何.save（）到另一个类/函数，如：

def save_page(request):

    # contains 3 fields

    form = sample_tableform(request.POST)
    if request.method == 'POST':
        if form.is_valid():

    #send a confirmation code to email
    #redirect to code confirmation page

def valcode(request):

    #contains 1 field

    sub_form = confirmform(request.POST)
    if request.method == 'POST':

        if sub_form.is_valid():

            #compare if code from save_pages matches the input field
            # if it matches then the data can be stored

            form.save()
            subform.save()

是否有可能？

我喜欢使用会话的想法，但我该如何实现呢？

Answer 1

假设您的代码来自views.py，答案是您不能。

视图不起作用（HTTP也不起作用）。如果要在后续HTTP请求之间访问数据，则必须将其保留在某处。

在您的情况下，您可能需要使用model将验证代码存储在数据库中：

# models.py
from django.db import models

class ValidationCode(models.Model):
    code = models.CharField(max_length=10, unique=True)
    creation_date = models.DateTimeField(auto_now_add=True)
    is_validated = models.BooleanField(default=False)

# views.py

def save_page(request):

    # contains 3 fields

    form = sample_tableform(request.POST)
    if request.method == 'POST':
        if form.is_valid():

    validation_code = ValidationCode(code="random_code_here")
    validation_code.save()

    # send email with the code here    
    #redirect to code confirmation page

def valcode(request):

    #contains 1 field

    sub_form = confirmform(request.POST)
    if request.method == 'POST':

        if sub_form.is_valid():

            try:
                code_from_db = ValidationCode.objects.get(code=form.fields['code'])
            except ValidationCode.DoesNotExist: 
                # Not code matching input exist in database
                # return some error to the user

            # code exist in db, just mark it as validated
            code_from_db.is_validated = True
            code_from_db.save()

Answer 2

          <td>{{ country.name }}</td>
          <td>{{ country[1960] }}</td>
          <td>{{ country[1970] }}</td>
          <td>{{ country[1980] }}</td>
          <td>{{ country[1990] }}</td>
          <td>{{ country[2000] }}</td>
