annotate roundup/rest.py @ 5632:a29a8dae2095
Initial implementation of function to return data for / and /data
endpoints under /rest/.
/rest/ returns:
1) default_version of the interface and supported_version array
2) list of links with rel and uri properties that indicate
what assets are available under /rest. E.g. /rest/data
/data returns:
a list of possible assets (e.g. issue, user, keyword, status)
and links for accessing those assets.
E.G.
{
"data": {
"keyword": {
"link": "https://example.net/demo/rest/data/keyword"
},
"user": {
"link": "https://example.net/demo/rest/data/user"
}, ...
}
}
Both of these are currently hand coded. Others will be doing more
development on the rest interface. These two examples are meant to
spark discussion on what the payloads returned by the rest interface
should look like and give some ideas around HATEOAS.
