Hi, and thanks for your question. As explained in the react-admin contributing guide, the right place to ask a "How To" question, get usage advice, or troubleshoot your own code, is StackOverFlow.

This makes your question easy to find by the core team, and the developer community. Unlike Github, StackOverFlow has great SEO, gamification, voting, and reputation. That's why we chose it, and decided to keep GitHub issues only for bugs and feature requests.

So I'm closing this issue, and inviting you to ask your question at:

http://stackoverflow.com/questions/tagged/react-admin

And once you get a response, please continue to hang out on the react-admin channel in StackOverflow. That way, you can help newcomers and share your expertise!

Sorry. But I thought this is a bug. No data shown in DataGrid.

[djhi]

It's not. This is a feature used in all our examples, which work, so there is something wrong with your code and StackOverflow is where you should ask for help.

@zhouhao27 Did you manage to make it work? I'm having the same problem but I don't know if it's my fault or if it is a bug

[gabrielperales]

Ok, It was my fault. The problem was that there was not a resource in the Admin component for the resource we are making reference in ReferenceManyField. Read more https://github.com/marmelab/react-admin/issues/1903#issuecomment-396900348

@zhouhao27, probably not actual anymore, but for those finding this in the future, usually this problem occurs when you didn't define a proper resource in the <Admin> component. So, in order to fix your problem @zhouhao27, you'd have to have something along these lines:

<Admin ...>
    <Resource ...> // other resources
    <Resource name="comments">
</Admin>
