I used the classes below, allowing users to edit their own profile after registering and it works well. I achieve this using get_query and get_count_query.

However, if the current user is administrator, how can I customize it to let him/her view all users' profiles instead of just his/her own profile? Thanks in advance. 

 from flask_admin.contrib.sqla.view import ModelView, func

 class User(db.Model, UserMixin):
   id = db.Column(db.Integer, primary_key=True)
   first_name = db.Column(db.String(255))
   last_name = db.Column(db.String(255))
   email = db.Column(db.String(255), unique=True)
   password = db.Column(db.String(255))

   def __str__(self):
     return self.email

 class UserView(ModelView):
   """
   Restrict only the current user can see his/her own profile
   """
   def get_query(self):
      return self.session.query(self.model).filter(self.model.id==current_user.id)
   def get_count_query(self):
      return self.session.query(func.count('*')).filter(self.model.id==current_user.id)

You can define another custom ModelView for administrator. For example:

class UserViewForAdmin(ModelView):

    def is_accessible(self):
        return current_user.has_role("admin")
    def inaccessible_callback(self, name, **kwargs):
        return redirect(url_for("security.login", next=request.url))

    pass

admin = Admin(name="Flask-Admin Example")

admin.add_view(UserView(User, db.session, name="Profile")
admin.add_view(UserViewForAdmin(User, db.session, name="UserList", endpoint="users")

The is example assume you use Flask-Security to do user management.

Another option here is to check the user and handle accordingly in y our get_query or get_count_query such as:

def get_query(self):
  if current_user.username == 'admin':
    return self.session.query(self.model)
  else:
    return self.session.query(self.model).filter(
      # your existing filter for user
    )

Note: the above uses current_user from flask_security but can be adapted to other logic easily.
