Hi all, I'm doing this and it works ZnClient new method: #PUT; url: 'http://127.0.0.1:5984/baseball/2'; contents: (NeoJSONWriter toString: { 'foo' -> 'baz'} asDictionary); contentType: ZnMimeType applicationJson; execute. But if try to use a contentWriter it fails because it can't determine the contentType of the entity. ZnClient new method: #PUT; url: 'http://127.0.0.1:5984/baseball/2'; "contentType: ZnMimeType applicationJson;" contentWriter: [ :entity | NeoJSONWriter toString: entity ]; contents: { 'foo' -> 'baz'} asDictionary; execute. If I uncomment the "contentType:" message send it complains about setting the content type before setting the entity, which makes sense but baffles me. My Idea is to directly pass the object as contents, and let the content writer deal with how it's going to be serialized on the request (a JSON string, for the most part). Although the first expression works, I know it can be done better, but I can't manage to get it working :) Thanks, ps: I also wonder by there aren't #bePut, #bePost, #beDelete, etc. convenience methods instead of passing the HTTP method as a symbol :) Esteban A.
