Question

I am trying to show image using template in Django:

template.html:

<img src='{{ url }}' alt="" />  

{{ url }} define in views.py

views.py:

blob_key =str(product.key())
url = images.get_serving_url(blob_key)

product – simple object, define in models.py:

class Product(db.Model):
      name = db.StringProperty()
      price = db.FloatProperty()
      added = db.DateTimeProperty(auto_now_add=True)
      image = db.BlobProperty(default=None)

After all, I get url = u'http://localhost:8080/_ah/img/ag5kZXZ-dmVydGlrYWwtM3INCxIHUHJvZHVjdBgEDA'

In admin console item with id = ag5kZXZ-dmVydGlrYWwtM3INCxIHUHJvZHVjdBgFDA, exist.

But in brawser i don’t see image.

Python 2.7

1. What am I doing wrong?
2. What other method to display image in GAE, using Django?

Answer 1

You seem to be using your Product instance’s key as the basis for the URL, rather than the key to the image blob. Surely you mean:

url = images.get_serving_url(product.image)
