Methods (key(), name(),...) are converted into propertie in a template.

[Sylvain]

Hi,

How is it possible that the "methods" (key(), Name(),...) are
converted into "properties" in a template.

I've an easy example :

In my python file i've an Image model :

Class Image(db.Model):
label = db.StringProperty()

and then i can do :

im = Image()
logging.info(im.key().name()) <--- it works
logging.info(im.key.name) <--- error "AttributeError"

but in my template, if i send the object 'im' (as dic in the render
function) i can do :
{{ im.key.name }} <-- it works, i've got the key_name
{{ im.key().name() }} <-- error "TemplateSyntaxError"

How is it possible that the template can convert Methods into
Properties ? ;)

Thank you

That's a feature of the Django Templates.

From the Django docs:

Technically, when the template system encounters a dot, it tries the
following lookups, in this order:

Dictionary lookup
Attribute lookup
Method call
List-index lookup

Hope that helps.
