如何正确显示某些'shop'的'staff'？

Question

正如您在图片中看到的那样，我有一个名叫 Max Barren 的员工，但问题是他只与这些商店中的一家有联系。仅在这些商店之一下，如何为该员工正确编写代码？

views.py

def list_view(request):

    context = {}

    context['library_dataset'] = VideoLibrary.objects.all()
    context['staff_dataset'] = Staff.objects.all()
    context['rank_dataset'] = Rank.objects.all()
    return render(request, 'app/list_view.html', context)

at views.py 我从 VideoLibrary 模型中获取地址和商店名称等对象，并从 Staff 模型中获取 staff_name 和性别等对象，并将其放入 list_view.html

models.py

class VideoLibrary(models.Model):
    shop_name = models.CharField(max_length=264)
    adress = models.TextField(max_length=264, default='')

    def __str__(self):
        return self.shop_name

    class Meta:
        verbose_name_plural = "Video Libraries"


class Staff(models.Model):
    staff_name = models.CharField(max_length=264)
    living_adress = models.TextField(max_length=264)
    gender = models.CharField(max_length=264)
    age = models.IntegerField()
    staff_rating = models.IntegerField()
    shop_name = models.ForeignKey(VideoLibrary, on_delete=models.CASCADE)

    def __str__(self):
        return f'{self.staff_name}'

    class Meta:
        verbose_name_plural = "Staff"


class Rank(models.Model):
    # rank_id = models.AutoField(primary_key=True, unique=True)
    staff_name = models.ForeignKey(Staff, on_delete=models.CASCADE)
    rank_name = models.CharField(max_length=264)

    def __str__(self):
        return f'{self.rank_name}, {self.staff_name}'

    class Meta:
        verbose_name_plural = "Ranks"

我想我在 list_view.html 的代码遇到了一些问题，但我不知道如何解决

list_view.html

<div class="main">
      {% for data in library_dataset %} Shop name:
      <br />
      <br />
      {{ data.shop_name }} <br />
      {{ data.adress }} <br />

      <td><a href="{% url 'update_shop' data.id  %}">
        <button type="button">Edit Shop Details</button>
        </a></td>

      <br />
      Staff that work in the shop:
      {% for data in staff_dataset %} Shop name:
      <br />
      <br />
      {{ data.staff_name }} <br />
      {{ data.gender }} <br />

      <td><a href="{% url 'update_staff' data.id  %}">
        <button type="button">Edit User Details</button>
        </a></td>
      <br />
      <br />
------------------------------------------------------------------------------------------------------------
      <br>
      {% endfor %}
      {% endfor %}

Answer 1

您正在将所有 VideoLibrary 对象和所有 Staff 对象传递给上下文。所以当你在做

{% for data in library_dataset %} 
   Displaying data of all shops
  {% for data in staff_dataset %}
   Displaying data of all staff
  {% endfor %}
  {% endfor %}

您为数据库中的每个商店显示数据库中的每个用户。您应该使用 VideoLibrary 对象中的相关员工姓名。更多相关信息：https://docs.djangoproject.com/en/4.0/topics/db/queries/#backwards-related-objects 在你的情况下，它可能是 .staff_set.all() 来获取与商店相关的所有员工对象，所以你的 html 代码将是：

{% for data in library_dataset %} 
   Displaying data of all shops
  {% for staff in data.staff_set.all %}
   Displaying data of staff related to libary
  {% endfor %}
  {% endfor %}
