[英]Django: displaying foreign key model in parent model's detail view template
[英]Display foreign key info within Django Detail View Template
正如標題所說,我有一個通過 Django 模板呈現的詳細視圖。 我有一個外鍵,我也想在該詳細視圖中顯示它,但我無法讓它工作。 我已經嘗試了一切,但我得到的只是基本的詳細視圖模板,沒有外鍵信息。 任何幫助將不勝感激。
這是我到目前為止所得到的:
楷模:
class Cust(models.Model): #this is the main model
id = models.UUIDField(
primary_key=True,
default=uuid.uuid4,
editable=False)
email = models.CharField(max_length=200)
firstName = models.CharField(max_length=200)
lastName = models.CharField(max_length=200)
watchmanSlug = models.CharField(max_length=200, unique=True)
class Watchman(models.Model):
group = models.ForeignKey(Cust, on_delete=models.CASCADE,to_field='watchmanSlug',
related_name='watchman_group_slug')
uid = models.CharField(max_length=500)
computer_name = models.CharField(max_length=500)
computer_url = models.CharField(max_length=500)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
意見
class CustomerDetailView(DetailView):
model = Cust
template_name = 'cust/cust_detail.html'
def get_context_data(self, ** kwargs):
context = super(CustomerDetailView, self).get_context_data( ** kwargs)
context['computer_name'] = Watchman.objects.all()
return context
詳細模板
<tbody>
<ul>
{% for p in watchman_group_slug.all %}
<li>{{ watchman.computer_name }}</li>
{% endfor %}
</ul>
</tbody>
您可以通過以下方式訪問相關的Watchman
對象:
<tbody>
<ul>
{% for p in object.watchman_group_slug.all %}
<li>{{ p.computer_name }}</li>
{% endfor %}
</ul>
</tbody>
所以使用object. watchman_group_slug.all
object. watchman_group_slug.all
和p
的.computer_name
。
