[web2py] Re: RESTful interfaace

[Massimo Di Pierro]

You can do:

@request.restful()
def api():
    response.view = 'generic.json'
    def GET(tablename,id):
        if not tablename=='person': raise HTTP(400)
        return dict(person = db.person(id))
    def POST(tablename,**fields):
        if not tablename=='person': raise HTTP(400)
        return db.person.validate_and_insert(**fields)
    return locals()


and this:

@request.restful()
def api():
    response.view = 'generic.'+request.extension
    def GET(*args,**vars):
        patterns = [
            "/friends[person]",
            "/friend/{person.name.startswith}",
            "/friend/{person.name}/:field",
            "/friend/{person.name}/pets[pet.owner]",
            "/friend/{person.name}/pet[pet.owner]/{pet.name}",
            "/friend/{person.name}/pet[pet.owner]/{pet.name}/:field"
            ]
        parser = db.parse_as_rest(patterns,args,vars)
        if parser.status == 200:
            return dict(content=parser.response)
        else:
            raise HTTP(parser.status,parser.error)
    def POST(table_name,**vars):
        if table_name == 'person':
            return db.person.validate_and_insert(**vars)
        elif table_name == 'pet':
            return db.pet.validate_and_insert(**vars)
        else:
            raise HTTP(400)
    return locals()

$ curl -d "name=Tim" http://127.0.0.1:8000/myapp/default/api/friend.json
{"errors": {}, "id": 1}
$ curl http://127.0.0.1:8000/myapp/default/api/friends.json
{"content": [{"info": null, "name": "Tim", "id": 1}]}
$ curl -d "name=Snoopy&owner=1" http://127.0.0.1:8000/myapp/default/api/pet.json
{"errors": {}, "id": 1}
$ curl http://127.0.0.1:8000/myapp/default/api/friend/Tim/pet/Snoopy.json
{"content": [{"info": null, "owner": 1, "name": "Snoopy", "id": 1}]}

or even

@request.restful()
def api():
    response.view = 'generic.'+request.extension
    def GET(*args,**vars):
        patterns = 'auto'
        parser = db.parse_as_rest(patterns,args,vars)
        if parser.status == 200:
            return dict(content=parser.response)
        else:
            raise HTTP(parser.status,parser.error)
    def POST(table_name,**vars):
        return db[table_name].validate_and_insert(**vars)
    return locals()
