按钮与Django来选择项目

Question

我有6个按钮，这是选择购买的东西。您不能做出多种选择，只能选择一种，并自动选择该项目并将您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，积分等）嵌入到每个按钮中，以便它们在结帐中使用。我最初的方法是我在Django.admin中动态地创建了这些项目，而不是在其中单独选择了一个项目的页面，而是通过模型（bono）从管理员中创建的项目中选择了一个复选框已创建。但是，我需要将这些项目硬编码到各个按钮中，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，并会根据请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，但不会发布任何内容到模型。 用于包装的模型如下：

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:') 

我需要做的圆圈，在点击，通过相关信息到模型和重新路由到结账。

只有一个按钮的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> 

页面完整的HTML：

{% load static %}

Answer 1

创建（在我的例子DataStorageModel）的模型，存储所有的您的数据库中的信息，并通过某个名称字段引用它。

把这个名字给您的提交按钮的名称标签，如：

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

然后在你的views.py您在request.POST名称：

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

更新：

我刚才看到你打算在html标签中存储价格。切勿这样做！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()
