Question

我有6个按钮，可以选择买东西。您无法进行多项选择，只能选择一项，然后自动选择该项目并重新路由到结帐部分。我的问题是，使用Django，我如何将这些按钮的值（即价格，信用等）嵌入到每个按钮中，以便它们用于结账时使用的按钮。我最初的方法是我在Django.admin中动态创建项目，而不是让你单独选择一个项目的页面，而不是一个复选框，从我通过模型（bono）在管理员中创建的任何项目中选择我创造了。但是，我需要将项目硬编码到单个按钮中，而不是依赖于Django.admin和服务器。

我附上了一个示例html和图片显示按钮，并会根据要求添加任何其他项目。我根本不知道应该包括哪些项目：编辑：我目前正在使用链接标记重新路由到不同的页面，但不会向模型发布任何内容。包的模型如下：

class CreditPackage(models.Model):
    name = models.CharField(max_length = 400, null=True, blank = True, verbose_name = 'Credit Package Name')
    description = models.TextField(max_length = 10000, null=True, blank = True, verbose_name = 'Description')
    price = models.IntegerField(null=True, blank = True, verbose_name = 'Price')
    nr_credits = models.IntegerField(null=True, blank = True, verbose_name = 'Number of Credits:')
    on_sale = models.BooleanField(null=False, blank = False, verbose_name = 'On Sale:')

点击后，我需要制作圈子，将相关信息传递给该模型并重新路由到结帐。

其中一个按钮的html：

<div class="col-xs-12 col-sm-12 col-md-4 col-lg-4 text-center bonoint">
              <a href="{% url 'student-packages' %}">
              <div class="circle" style="background: #0045ab" ><span style="font-weight:bold; font-size:60px;"  >3</span><br> Credits</div>
                <div id="price">25€</div>
                <div id="savings">
                  {% trans 'You save' %} <span style="font-weight:bold">5€</span><br><br>
                    {% blocktrans %} Ideal if you want to<br>
                  try out Milingual {% endblocktrans %}</br>.
                </div></a>
            </div>

Answer 1

创建一个模型（在我的示例中为DataStorageModel），它存储数据库中的所有信息并通过某个名称字段引用它。

将此名称添加到带有名称标签的提交按钮，例如：

<input id="create" type="submit" name="create" value="Create"/>

然后在views.py中检查request.POST中的名称：

if request.POST.get('create'):
    obj = DataStorageModel.objects.get(name='create')
    ...

更新：

我刚看到您打算将价格存储在html标记内。永远都不要！人们可以改变这些价值......尽可能少地给客户。因此，您需要一个模型来存储您的价格等。

DataStorageModel(model.Model):
    price = models.DecimalField(max_digits=8, decimal_places=2)
    credits = models.PositiveIntegerField()
    name = models.CharField()

用Django按钮来选择项目
