Hi All,
I heard about web2py following this question:
http://stackoverflow.com/questions/5899483/generate-rest-based-service-from-database-schema
My goal is to create a RESTful web service from a DB, such that when the DB
is modified, no code changes would be needed.
Questions:
1. When creating the DB schema to be extracted, should I add an 'id' field?
If I do, the resulted 'legacy_db_web2py_code' string contains an 'ID' field
in 'define_table'. However, the documentation says such field is already
created implicitly. If I don't, I need another PK to create relations with
foreign keys.
2. I've found an example here:
http://www.web2pyslices.com/slice/show/1534/restful-services-with-curl-andor-python
but PUT and DELETE won't work (GET and POST do work). any suggestions?
3.I've written a small scitpt (attached) which wraps
'extract_mysql_models'. Feedback would be welcomed.
Thanks in advance
