我有個問題。我如何從models.py傳遞資料（可能是def）我需要這個在未來按類別過濾
class Tag(models.Model):
.......
category = models.ForeignKey(Category, null=True, on_delete=models.PROTECT, related_name='category', verbose_name='Tag category')
......
def get_category(self):
return self.category
到views.py。這是行不通的
class GetDetailTag(DetailView):
model = Tag
template_name = 'main/catalog.html'
context_object_name = 'tag'
category = Tag.get_category
def get_context_data(self, *, object_list=None, **kwargs):
context = super().get_context_data(**kwargs,)
context['pansion_in_tag_list'] = Pansions.objects.filter(tags__slug=self.kwargs['slug'])
context['tags_in_category'] = Tag.objects.filter(category__slug = '...INSERT THE DATA FROM MODEL HERE...')
return context
我試圖在views.py中呼叫'def'（get_category）
反正？我怎么能這樣做？
uj5u.com熱心網友回復：
您可以從標簽中獲取它，因此：
{{ 標簽.category }}
或在DetailView：
class TagDetailView(DetailView):
model = Tag
template_name = 'main/catalog.html'
context_object_name = 'tag'
def get_context_data(self, *, object_list=None, **kwargs):
context = super().get_context_data(object_list=object_list, **kwargs)
context['pansion_in_tag_list'] = Pansions.objects.filter(
tags__slug=self.kwargs['slug']
)
context['tags_in_category'] = Tag.objects.filter(
category_id=self.object.category_id
)
# category = self.object.category (obtain the category)
return context轉載請註明出處，本文鏈接：https://www.uj5u.com/qukuanlian/526086.html
