我正在尝试在视图中使用 Django 模型方法。
楷模：
class stores(models.Model):
""" This is the store model """
seo_url = models.URLField() # SEO URL for flipdiscounts.in
storeURL = models.URLField() # Store URL
fallBackURL = models.URLField() # Fallback URL for couponURL
storeDescription = models.TextField() # Store Description
storeTags = models.ManyToManyField(tags) # All the tags associated with the store
storeName = models.CharField(max_length=30) # Store Name
storeSlug = models.CharField(max_length=400) # This is the text you see in the URL
updatedAt = models.DateTimeField(auto_now=True) # Time at which store is updated
storeImage = models.ImageField(upload_to="images") # Store Image
createdAt = models.DateTimeField(auto_now_add=True) # Time at which store is created
hash = models.CharField(max_length=10,unique=True) # Tag Hash for flipdisconts.in
storePopularityNumber = models.IntegerField(choices=PRIORITY_CHOICES,default=3) # Store Popularity Number
def Store_Tags(self):
"""Method to return tags related to store"""
return ','.join([t.tagSlug for t in self.storeTags.all()])

"""Method to get tag hash related to store for flipdiscounts.in"""

count = ",".join([str(a.id) for a in t.coupons_set.all()])

return len(count)

class Meta:
"""Meta class to control display Behavior of the Model name """
verbose_name_plural = "Stores"
def __unicode__(self):
"""Method to display string correctly"""
return unicode(self.storeName)
def save(self, *args, **kwargs):
self.hash = _generateHash() # Generate Hash for flipdiscounts.in
self.seo_url = "discounts-in-" + self.storeName.replace(".","-") # Generate SEO URL for flipdiscounts.in
super(stores, self).save(*args, **kwargs)
class tags(models.Model):
""" This is the tag model """
seo_url = models.URLField() # SEO URL for flipdiscounts.in
tagDescription = models.TextField() # Tag Description
tag = models.CharField(max_length=200) # Tag name
tagSlug = models.CharField(max_length=400) # Extra info can be added to the existing tag using this field
updatedAt = models.DateTimeField(auto_now=True) # Time at which tag is updated
createdAt = models.DateTimeField(auto_now_add=True) # Time at which tag is created

我如何tags.storeNames()在我的views.py中使用。有人可以帮帮我吗
