Flask App: AttributeError: 'unicode' object has no attribute 'view_user_events'

Question

Background: Flask app

I'm trying to pull a parameter out of a url and pass it to the app to make the appropriate call from the model, but I'm getting this error whenever I try to visit the url:

AttributeError: 'unicode' object has no attribute 'view_user_events'

Here's the code in which the error is occurring:

@app.route('/timeline/<username>')
def get_user_timeline(username):
    event_list = username.view_user_events(username)
    def other_timeline(username=None):
        if username and username != current_user.username:
            try:
                user = models.User.select().where(
                    models.User.username**username).get()
            except models.DoesNotExist:
                abort(404)
            else:
                event_list = user.events
        else:
            return redirect(url_for('timeline'))
        if username:
            return render_template('userpages/timeline.html', event_list=event_list, user=user)

How can I get rid of this error? (And feel free to point out any other flagrant mistakes - I'm a newbie working through this, so there are likely others.)

Hey Kyle, looking at your code, the error is in line 3:

@app.route('/timeline/<username>')
def get_user_timeline(username):  # <-- username pass in as unicode string argument
    event_list = username.view_user_events(username)   # <-- trying to run username.view_user_events() method
    # Error the unicode object 'username' does not have a method called 'view_user_events()'
    # You likely want to get the 'event_list' after you figure out the 'user' below

    def other_timeline(username=None):
        if username and username != current_user.username:
            try:
                user = models.User.select().where(
                    models.User.username**username).get()
            except models.DoesNotExist:
                abort(404)
            else:
                event_list = user.events
        else:
            return redirect(url_for('timeline'))
        # HERE, now that you have a 'user' object or returned with a 404,
        # you can get the list of user events with using 'view_user_events' 
        # event_list = .....view_user_events()   # <-- implementation dependent

        if username:
            return render_template('userpages/timeline.html', event_list=event_list, user=user)
