difficulty setting up and using Flask_whooshalchemy

Question

I'm currently working on a flask web app with a large database which meant that I had to discard the code I had initially written for WhooshAlchemy. The first time I tested it I got the following error.

   Post.query.whoosh_search('phone').all()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Abdul\Anaconda3\lib\site-packages\flask_whooshalchemy.py", line 103, in whoosh_search
    if not isinstance(query, unicode):
NameError: name 'unicode' is not defined

does this have anything to do with python 3 renaming Unicode to str a couple of years ago or is it something else? I tried changing the Unicode into str but that did not seem to fix the problem? any useful input would be appreciated.

The library you're trying to use does not support Python 3: https://github.com/gyllstromk/Flask-WhooshAlchemy/issues/60 — Ilja Everilä, Nov 27 '19 at 09:14

Disclaimer: Flask_whooshalchemy is no longer supported and does not work with python 3.0+.

Solution: you either have to use a custom solution or use Flask m-search which works just fine.

Here's a link to flask m-search just in case anybody was facing the same problem.

A quick example would be like the following:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_msearch import Search

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////tmp/test.db'
db = SQLAlchemy(app)
search = Search()
search.init_app(app)

class User(db.Model):
    __searchable__ = ['id', 'username', 'email']
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True, nullable=False)
    email = db.Column(db.String(120), unique=True, nullable=False)

    def __repr__(self):
        return '<User %r>' % self.username
