rest - How to handle optional body with PUT or DELETE HTTP Requests (in a Play Application)? -


reservation resource 4 fields id, datacenter, startdate, enddate

i wish handle both types of requests:

  1. in there body list of datacenters

  2. in don't send body (in case perform operation on datacenters present in database).

without body:

put /reservation/123/end

delete /reservation/123

with body:

put /reservation/123/end

{     "datacenters": ["ams", "clt"] }

delete /reservation

{     "datacenters": ["ams", "clt"] }

the problem being server expects body valid json when there no body (which isn't case when body empty). best way handle use case?

i found 1 possible solution, not clean one, works.

for put 

    json     .fromjson[optionaldatacenters](request.body.asjson.getorelse(jsarray()))     .getorelse(optionaldatacenters(none))     .datacenters

for delete 

action.async(parse.raw) { request =>   val datacenters =     request.body       .asbytes()       .map(         bytes =>           if (bytes.size > 1) json.parse(bytes.toarray).as[optionaldatacenters]           else optionaldatacenters(none)       )       .getorelse(optionaldatacenters(none))       .datacenters

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
