QUESTION
I have a problem with rules that I can not solve, I have built a project, that users can register, and when they register I want to give them permission. Something like the firebase auth. (I do not want to use auth within rules).
Every time a user logs in to my project, I update the database in the isOnline field, to true.
I have firestore users, and each user has a boolean field isOnline, for example in the image I added:
I have a collection of users, inside I have the names of the users, and inside I have a field of isOnline.
Here in the picture, frontend4 user isOnline's field is true, so for him I will give permission to use the site.
If the field isOnline come true, it means the user is logged in
This is the rules I'm trying to do, I want to access my user's isOnline, and check if it's isOnline, and if so, then give it access.
The rules I made do not work, I do not quite understand why.
...ANSWER
Answered 2021-Apr-19 at 07:38Your case is really problematic, the only way to do security in rules is to access your correntUser or auth. Because you connect through the nodejs, you only return json object and there will be no access to these objects.
For you to have access to these objects what you need to do is connect once more, in react itself, with the same firebase and that's how you enjoy all the worlds that firebase has to offer.
When you log in again, the user does not need to know about it, since when you log in you will reset the password, and choose a random password, it will solve all your problems.
I think this is the most likely solution, but it is not for production
Please update me.
QUESTION
What I'm Trying to do: I have the following react component, which is chat box, which toggles to view on clicking a button. The chatBox will be opened or closed according the value in the state 'open'. When the user clicks on the chat button, the function 'toggleChat' is run, which just toggles the value of 'open' state between true and false.
Problem: Now the problem is, when a new message is received, I am trying to keep the count of unread messages, if the chatBox isn't 'opened'. But it fails. In my opinion it should work, but the 'open' state is not what I expect it to be sometimes. Sometimes, even though the chatBox is opened, the open state inside is 'false'.

Also add const [msgArr, setMsgArr] = useState([]); if it is not there.
QUESTION
Background: I am creating one app, where the internet connection status should be shown to the user dynamically. The result is already showing but I want the background color to be changed dynamically. I tried to implement it in setState() but the text color is not getting changed. and I don't know how to implement setState() inside button without onPressed. main code:
...ANSWER
Answered 2021-Apr-12 at 17:44You're almost there, you just need to put all that functionality in the stream listener you have setup and not in the build method.
Since you already have a listener following changes in connectivity status, that listener just needs to update a Color variable. Here's a simplified example.

QUESTION
I am trying to have friends page, where I could see who is online and who is offline. Updating document to set user online is no problem. I have a useEffect that checks if currentUser exists and it would update isOnline to true. But is there a way to set isOnline to false, when user leaves Website. If user where to click signOut then its fine I could first update isOnline to false then signOut, but if user just exits how do I know he is offline? sorry if my question is confusing.
...ANSWER
Answered 2021-Mar-22 at 17:17You are actually looking for a system to detect "presence". As explained in the Firebase documentation, you can use the Realtime Database to add presence to your Cloud Firestore based app.
This Firebase Blog article from 2013 is also interesting to read, to get more details on the Realtime Database presence system.
