Can not create object

[zhouhao27]

I created a few collections in firebase store: Posts, Comments, Tags etc and created a few corresponding components. There is no problem to save(create) Post. But when I save(create) other objects like Comment and Tag. I got the following error message:

Function Firestore.collection() requires its first argument to be of type non-empty string, but it was: undefined

Here is my code:

import React from "react";
import {
  Create,
  SimpleForm,
  TextInput,
} from "react-admin"

const CommentCreate = props => (
  <Create {...props}>
    <SimpleForm>
      <TextInput source="comment" />
    </SimpleForm>
  </Create>
);

export default CommentCreate;

The other components are doing the same thing.

Any suggestion? Thanks.

I found the issue. It works when I add this:

const trackedResources = [
  { name: 'posts', isPublic: true }, 
  { name: 'users', isPublic: true },
  { name: 'tags', isPublic: true}
]

Two questions:

1. What is trackedResources used for?
2. What about is I only allow to insert after user login instead of setting isPublic to false.

1. trackedResources is used to initialize the Firestore collections. This is basically a list of all collections that can be used in react-admin.
2. Currently isPublic does not do anything, you can safely ignore it. It's a leftover from ra-data-firebase-client library I branched from.

this should be added to the documentation which is a must!!! come on Rafal

@rafalzawadzki Thanks for your reply. Another two questions for you:

1. Is realtime supported? For example, I want to build channel to broadcast news.
2. I saw your demo to upload image as base64. But I'm wondering if it's possible to upload files to firebase storage (bucket)

@x5engine thank you - should definitely cover this in the documentation (as lots of other things). I'm currently swamped with other work, so it will take a while (PRs are also welcome ;))

@zhouhao27

1. Realtime updates are unfortunately not supported, I am not even sure if it would be possible to accomplish with react-admin.
2. Uploading to Firebase Storage is not supported, but definitely possible. I do not foresee adding support for it in any soon future though, as there are other more pressing issues to solve first :)

@zhouhao27 I'm studying realtime support on #5, with ra-realtime, keep an eye.
