[web2py] Re: Can web2py "front-end" an API?

[Luis Valladares]

What if you use a model-less aplication? thats the way we handled this, we 
have a web2py application that consumes a lot of microservices, this 
application doesnt have any DB object and doesnt use the dal, it makes HTTP 
request to the api inside the controllers (Using the python requests 
library), format it and send to the views.

Hmm... Model-Less application shouldn't be regarded as a web2py application
without model properly defined... Model-Less web2py application is just an
application written with web2py where the models are not defined in the
models/ folder of web2py to avoid cost of parsing models definition at each
request... So some web2py users have developped the model-less approach
that consist in the definition of the models into a modules which is then
imported once... That way database models are not parsed at each request
anymore... This is only required when your application need to scale up and
performance start of getting an issue and you should start thinking to
refactoring it to allow you app to support an raising charge related to the
popularity of your web2py site a webapp. It may be worth to consider
model-less approach also when you have many tables and the models files
parsing start of getting an issue...

Before take this path you really need to make sure what is the reason of
your performance issue by profiling you application properly to find the
bottle neck then start thinking on how you are going to resolve it and
refactor your app. Model-Less issue come with some penality in term of
web2py functionnalities, so you really want to take this path when you
really need to.

I think it's clear that by "model-less," Luis meant no db/database model 
definitions (at least not with regard to third party API's). In the past, 
the term "model-less" has also been used to describe an architecture that 
avoids use of files in the /models folder. The term is ambiguous because a 
"model" can either be a file in the /models folder or a database model 
(defined anywhere).

You could make a a DAL adapter yes. In fact one could argue that all DAL 
adapters are facades for APIs.

Maybe check out the IMAP adapter
