Learn more about Teams I have autocomplete function as a separate file - autocomplete.py. The autocomplete is being imported into .py as follows:

from xyzapp.autocomplete import autocomplete
The line that throws error in autocomplete.py is the following:
@app.route('/autocomplete',methods=['GET'])
The structure of the application is using blueprints and looks as follows:
appcontainer
     |--run.py
     |--xyzapp
          |--__init__.py
          |--autocomplete.py
          |--blueprint_folder_1
          |--blueprint_folder_2
          |--static
The whole error message looks like this:
 @app.route('/autocomplete',methods=['GET'])
 AttributeError: module 'flask.app' has no attribute 'route' 
Any ideas what I am doing wrong?   
UPDATE:
The autocomplete.py looks as follows:
from flask import Flask, render_template, redirect, url_for, request, session, flash, app, Blueprint, jsonify
@app.route('/autocomplete',methods=['GET'])
def autocomplete():
    database='backbone_test'
    db=client[database]
    all_names=list(db.ids.find({},{"current_name":1,"_id":0}))
    return json.dumps(all_names) 
The __init__.py file looks as follows:
from flask import Flask, render_template, Blueprint, jsonify, session
import jinja2
class MyApp(Flask):
  def __init__(self):
    Flask.__init__(self, __name__)
    self.jinja_loader = jinja2.ChoiceLoader([self.jinja_loader,jinja2.PrefixLoader({}, delimiter = ".")])
    def create_global_jinja_loader(self):
        return self.jinja_loader
    def register_blueprint(self, bp):
        Flask.register_blueprint(self, bp)
        self.jinja_loader.loaders[1].mapping[bp.name] = bp.jinja_loader
app = MyApp()
from xyzapp.autocomplete import autocomplete
from xyzapp.blueprint_folder_1.some_file import bp_1
app.register_blueprint(bp_1)
                Just wanted to make sure you had a function underneath, after all, @app is a function decorator.

                your code in this line : from flask import Flask, render_template, redirect, url_for, request, session, flash, app, Blueprint, jsonify  you import app from flask, try to import it form init,   use this ( from . import app)

I'm sorry this is a bit of a long shot, I'm not familiar with this way of running a Flask app, but it seems you create your own instance of the Flask class called MyApp and initialise it under the variable app.
I'm not 100% and may be completely wrong, but I think your problem lies in the __init__ of MyApp
                Yes, I have the following line in autocomplete.py: from flask import Flask, render_template, redirect, url_for, request, session, flash, app, Blueprint, jsonify
