VisualizaçõesHow can I get only the users with roles of 'user'?
I am using Firebase for this app. Under each documents of a user, I have this array roles. For normal users, their roles would just be user. For an admin, it would be user and admin. I want to retrieve all of the normal users. However, the problem is that if I'll set it like this:
.collection("users")
.where("roles", "!=", "admin")
this will still show the user with an admin role.
How can I retrieve only those normal users and not the user with an admin role?

This would require an array-does-not-contain operation, which does not exist in Firestore.
You might want to consider storing the roles as a map with boolean values, so that you can query for where("roles.admin", "==", false).

You can use 'not-in' roles not in admin then you will get normal user
