如何在 django 的一个模板中使用两个模型

  • 772

问题是，有两个模型彼此不相关。这是models.py中的两个模型

class Item(models.Model):
    name = models.CharField(max_length=250, default="", verbose_name=_("Название работы"))
    slug = models.SlugField(max_length=250, default="", verbose_name=_("URL"))
    in_category = models.ForeignKey(Category, default="", verbose_name=_("Категория"))
    item_type = models.ForeignKey(ItemType, verbose_name=_("Тип Элемента"))
    description = models.TextField(_('Описание'), null=True, blank=True)
    images = models.ManyToManyField(Images, blank=True, verbose_name=_("Изображения"))
    sort = models.IntegerField(default="0", verbose_name=_("Сортировка"))
    is_active = models.BooleanField(default="True", verbose_name=_("Активно?"))
    date_pub = models.DateField(auto_now_add=True, blank=True, verbose_name=_("Дата добавления"))
    date_upd = models.DateTimeField(auto_now_add=False, auto_now=True, verbose_name=_("Дата редактирования"))

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return "/portfolio/items/%s/" % self.slug

    def get_category_url(self):
        return "/portfolio/category/%s/" % self.in_category.slug

    class Meta:
        verbose_name = 'Элемент'
        verbose_name_plural = 'Элементы'

class Settings(models.Model):
    name = models.CharField(max_length=250, default="", verbose_name=_("Наименование"))
    category_type = models.ForeignKey(CategoryType, verbose_name=_("Тип категория"))
    sort = models.IntegerField(default="0", verbose_name=_("Сортировка"))
    is_active = models.BooleanField(default="True", verbose_name=_("Активно?"))
    date_pub = models.DateField(auto_now_add=True, blank=True, verbose_name=_("Дата добавления"))
    date_upd = models.DateTimeField(auto_now_add=False, auto_now=True, verbose_name=_("Дата редактирования"))

    def __str__(self):
        return self.name

    class Meta:
        verbose_name = 'Настройка'
        verbose_name_plural = 'Настройки'

这是views.py中的类

class ItemList(ListView):
    model = Item
    template_name = 'itm_portfolio/main.html'

一般来说，实际的问题是，除了来自 Item 模型的数据之外，如何在 main.html 模板中显示来自 Settings 模型的数据？

python

  1. Best Answer

    解决方案非常简单：views.py

    class ItemList(ListView):
model = Item
template_name = 'itm_portfolio/main.html'

def get_context_data(self, **kwargs):
    context = super(ItemList, self).get_context_data(**kwargs)
    context['settings'] = Settings.objects.all()
    return context

    接下来，在 main.html 中，我们显示来自 Settings 模型的数据：

        {% for item in settings %}
        {{ item.category_type }}
    {% endfor %}

  2. 你可以不用get_context_data.

    class ItemList(ListView):
    model = Item
    template_name = 'itm_portfolio/main.html'

    @staticmethod
    def all_settings():
        return Settings.objects.all()

    在这样的模板调用中：

    {{ view.all_settings }}
