newby question about xml:root
Hi,
I am just trying jaydata today for the first time and have an odata service now running that presents documents from my MongoDB collection, without any changes needed to my documents.
But the resulting xml/json has one big problem. part of the URI has the word "undefined".
example: xml:base="http://localhost:3012undefined/Products"
This is after following this example very closely: http://jaydata.org/blog/install-your-own-odata-server-with-nodejs-and-mongodb
Is there a simple fix for this?
To add a bit to this, the links work great. But it seems that the URI path used when I set up express do not get passed to the object handling the request.
So links to the objects work like: http://localhost:3012/test/Products('NTQwNjAxOWMxMTcyZDVjMWQxNDMwZTRl')
but the handler just puts undefined instead of /test every time, in the resulting xml/json
Hi Miles, could you please paste here the client code that instantiates the OData context?
no need to paste the context :) you can downgrade to express version 3 and the issue will be solved. You can do this by the following instruction:
npm install express@3
downgrading to Express 3 (from 4.8.7) Worked!! Thank you for responding so quickly! I was not getting anywhere with reading the API and was going to try to look at the source code but I'm not very good with Javascript. Can I copy your answer to the other forum question on jaydata.org so before closing that discussion? (In can others look for the answer there via google) Also, if you need any help testing new jaydata releases to work with express4.x let me know. We are starting to add a lot of odata services now that MS PowerBI is getting used more here (for better or worse) and I really like how jaydata lets me adopt my documents in MongoDB to odata.

Splendid, thank your for your feedback and sharing your plans with our component. I close this issue, but feel free to reopen it or create a new one, keep in touch about your project and further releases.
Yes, is there any ETA on the next version of Jaydata which will hopefully support the latest version of Express?
Hi guys, The updated version with new express support will arrive in a couple of days! :) Stay tuned, someone from the team will update this ticket to notify you.
Hi, just published odata-server 1.3.7 supporting Express 4 to the npm registry. It's a much better and easier way to publish your OData service. Read more about JayData Server here: http://jaydata.org/blog/how-to-set-up-a-nodejs-odata-endpoint-with-odata-server JayService fix will be coming in the next release of JayData. Stay tuned!
