_etag not being returned for all docs in a collection #20

Closed rbarcelos closed 9 years ago

Hi,

I am using RestHeart to load all docs in a given collection from MongoDb. _etag is being returned randomly only for few docs ..

capture

You can try it out using the following url also:

Just to confirm: has the document 11 in your screenshot been created by RESTHeart or by a different client?

In fact, the _etag property is injected by RESTHeart at write time.

If a document has been created by a different client (e.g. mongo shell) the _etag won't be there. In this case RESTHeart won't enforce the etag match. At first update by RETHeart, the _etag will be automatically added.

Gotcha.. You are right.. the ones missing got created by a different client.. could you make this clear on the documentation ?..

Thanks
