Question

我有一个布尔字段，表示项目是否处于活动状态：

is_active = models.BooleanField(default=True)

看起来很简单，我的模板会显示有效的项目：

{% for p in products|dictsortreversed:"id" %}
    {% if p.is_active %}
    <a href="{{ p.get_absolute_url }}">
    {{ p.name }} 
    </a>
{% endif %}

由于某种原因，即使数据库中的字段为0，也会返回所有项目。当我取消选中django admin中的布尔字段时，它会在数据库中正确更新为0，但仍显示为在管理员中检查...

似乎django正在将该字段读为True，而不管布尔值。

模型

class Product(models.Model):
    name = models.CharField(max_length=255, unique=True)
    slug = models.SlugField(max_length=255, unique=True, help_text='Unique value for product page URL, created from name')
    price = models.DecimalField(max_digits=9, decimal_places=2, blank=True, default=0.00)
    old_price = models.DecimalField(max_digits=9, decimal_places=2, blank=True, default=0.00)
    image = models.CharField(max_length=50)
    is_active = models.BooleanField(default=True)
    quantity = models.IntegerField()
    description = models.TextField()
    meta_keywords = models.CharField('Meta Keywords', max_length=255, help_text='Comma-delimited set of SEO keywords for meta tag')
    meta_description = models.CharField('Meta Description', max_length=255, help_text='Content for description meta tag')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    categories = models.ForeignKey(Category, null=True)
    publish_date = models.DateField(blank=True, null=True)
    issue_one = models.CharField(blank=True, null=True, max_length=255)
    issue_two = models.CharField(blank=True, null=True, max_length=255)
    issue_three = models.CharField(blank=True, null=True, max_length=255)

    class Meta:
        db_table = 'products'
        ordering = ['-created_at']

    def __unicode__(self):
        return self.name

    @models.permalink
    def get_absolute_url(self):
        return ('catalog_product', (), {'product_slug': self.slug})

查看：

def index(request, template_name="catalog/index.html"):
    """ site home page """
    page_title = 'Visible Language Ordering'
    return render_to_response(template_name, locals(), context_instance=RequestContext(request))
