按钮不工作有问题

Question

我是一名想精通Django的学生。按钮不起作用。如果您按下 detail.html 中的按钮，我想将产品保存在数据库中，就像我购买了它一样。我的目标是获取 views.py 上所写的买家、日期和产品代码。但是，即使您现在按下按钮，也无法将其保存在 DB 中。有什么问题吗？

model.py

class Join(models.Model):
    join_code = models.AutoField(primary_key=True)
    username = models.ForeignKey(Member, on_delete=models.CASCADE, db_column='username')
    product_code = models.ForeignKey(Product, on_delete=models.CASCADE, db_column='product_code')
    part_date = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return str(self.join_code)

    class Meta:
        ordering = ['join_code']

Join/views

从日期时间导入时区

从 django.shortcuts 导入渲染

来自 zeronine.models 导入 *

def join_detail(request):
    product = Product.objects.all()

    if request.method == "POST":
        join = Join()
        join.product_code = product
        join.username = request.user
        join.part_date = timezone.now()
        join.save()

    return render(request, 'zeronine/detail.html', {'product': product})

detail.html

我不确定，但您的模板中有一个表单。也许这是导致问题的原因。

还有在 POST 部分。最好使用

join = Join.objects.create(product_code=product, ....)```
