flask-whooshalchemy3's Introduction

Flask-WhooshAlchemy3

Whoosh indexing capabilities for Flask-SQLAlchemy, Python 3 compatibility fork. Performance improvements and suggestions are readily welcome.

Inspired from gyllstromk's Flask-WhooshAlchemy.

Install

$ pip install flask-whooshalchemy3

..alternatively from source,

$ pip install git+git://github.com/blakev/Flask-WhooshAlchemy3.git@master

Quickstart

from datetime import datetime

import flask_sqlalchemy
import flask_whooshalchemy3
from whoosh.analysis import StemmingAnalyzer

db = flask_sqlalchemy.SQLAlchemy()


class BlogPost(db.Model):
    __tablename__ = 'posts'
    __searchable__ = ['title', 'content', 'summary']  # indexed fields
    __analyzer__ = StemmingAnalyzer()

    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(255), unique=True)
    content = db.Column(db.Text(32 * 1024))
    summary = db.Column(db.String(1024))
    created = db.Column(db.DateTime, default=datetime.utcnow)

Committing model instances to the session will write or update the Whoosh index.

db.session.add(BlogPost(title='First Post!', content='This is awesome.'))
db.session.commit()

Searching is done via Model.query.search(..). However, the request must be done within the Flask request context otherwise the database connection may not be established.

@app.route('/posts')
def posts():
    num_posts = min(request.args.get('limit', 10), 50)
    query = request.args.get('q', '')
    results = BlogPost.query.search(query, limit=num_posts)

Results are ordered by Whoosh's ranking-algorithm, but can be overwritten with SQLAlchemy .order_by.

yesterday = datetime.utcnow() - timedelta(days=1)
results = BlogPost.query
            .filter(BlogPost.created > yesterday)
            .search('first')
            .order_by(desc(BlogPost.created))

Flask Configuration

WHOOSH_ANALYZER (whoosh.Analyzer)

Sets the global text analyzer, available options in Whoosh documentation.
Default: StemmingAnalyzer.

WHOOSH_INDEX_PATH (str)

File path to where the text indexes will be saved.
Default: {cwd}/.indexes/*

WHOOSH_INDEXING_CPUS (int)

The number of system processes to spawn for indexing new and modified documents.
Default: 2

WHOOSH_INDEXING_RAM (int)

The amount of RAM, in megabytes, to reserve per indexing process for data processing.
Default: 256

WHOOSH_RAM_CACHE (bool)

Allows common queries and their fields to be stored in cache, in RAM.
Default: False

flask-whooshalchemy3's Issues

SQLAlchemy is locked to 1.1.13

Requirements.txt forces SQLAlchemy to 1.1.13 which is vulnerable to:
CVE-2019-7164
CVE-2019-7548

Can this be updated to work on SQLAlchemy 1.3 and later where these were patched?

AttributeError: 'result' object has no attribute 'id'

When searching, no error is thrown if the search does not produce result, but when results are available, flask-whoshalchemy3 throws an AttributeError as shown below

AttributeError: 'result' object has no attribute 'id'

BaseQuery object has no attribute 'search'

I followed the sample code in the readme but i end up with this error....no attribute search.

Is there more to be added to the sample code before i can make a search query ?

Flask' object has no attribute 'search_indexes'

When I am trying to create new index, using flask_whooshalchemy.create_index(app, Store), it throws Flask' object has no attribute 'search_indexes'.

I used this function to create indexes because my hunch is that it replaces old flask_whooshalchemy.whoosh_index(app, Store) function.

Though ReadMe file does not ask me to add flask_whooshalchemy.create_index(app, Store) at the end of the model I want to index, but if I don't do that, it throws me an error when I try to query using MyModel.query.search(query_string)

Issues with required version of SQLALchemy on Python 3.8+

Python 3.8 removes the time.clock() function. Recently SQLAlchemy removed this code altogether. As a result of the requirements.txt file specifying SQLALchemy version 1.3.12 Flask-WhooshAlchemy3 will not work on Python3.8+.

Null error in SQL Statement

class Product(db.model):
    __searchable__ = ['title', 'description']

    __analyzer__ = StemmingAnalyzer()
    __tablename__ = "Product"
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    description = db.Column(db.Text, nullable=True)

 query = request.args.get('q', '') -> Organization
 products = Product.query.search(query, limit=num_posts)

@datapilot.before_first_request
def bootstrap():
    flask_whooshalchemy3.search_index(datapilot, Product)

The query variable is being passed but the SQL query is built into SELECT * From Product WHERE null

AttributeError: module 'sqlalchemy.types' has no attribute 'Binary'

With the latest update to SQLAlchemy (1.4.22), the class Binary has been removed and replaced with LargeBinary. This change needs to be made in __init__.py.

how to make it works

WA2 is defunct. Is this package going to be maintained indepedently?

Flask-WhooshAlchemy for python2 is now deprecated. Will this package be maintained independently? Thanks.

AttributeError: 'BaseQuery' object has no attribute 'search'

Hi there,

Giving this a go.

Here is my config:

# Database
SQLALCHEMY_DATABASE_URI = 'sqlite:///db/site.db'
# turning on tracking so the search extension can track if anything in the database changes
SQL_TRACK_MODIFICATIONS = True

# set the location for the whoosh index
WHOOSH_INDEX_PATH = 'whooshIndex'
WHOOSH_ANALYZER = 'StemmingAnalyzer'

My model:

class Org(db.Model):
    __searchable__ = ['orgName', 'phone1', 'phone2', 'phone3', 'email1', 'email2', 'email3', 'backgroundInfo']
    __analyzer__ = StemmingAnalyzer()
    id = db.Column(db.Integer, primary_key=True)
    active = db.Column(db.Boolean, unique=False, default=True)
    orgName = db.Column(db.String(200), unique=True, nullable=False)
    posts = db.relationship('Log', backref='organisation', lazy=True)
    postalStreet = db.Column(db.String(200))
    postalTown = db.Column(db.String(60))
    postalState = db.Column(db.String(20))
    postalPostCode = db.Column(db.String(10))
    backgroundInfo = db.Column(db.String(1000))
    phone1 = db.Column(db.String(128))
    phone2 = db.Column(db.String(128))
    phone3 = db.Column(db.String(128))
    phone1Type = db.Column(db.String(24))
    phone2Type = db.Column(db.String(24))
    phone3Type = db.Column(db.String(24))
    email1 = db.Column(db.String(128))
    email2 = db.Column(db.String(128))
    email3 = db.Column(db.String(128))
    email1Type = db.Column(db.String(24))
    email2Type = db.Column(db.String(24))
    email3Type = db.Column(db.String(24))

    def __repr__(self):  # this is how our object is printed when we print it out
        return f"Org('{self.orgName}')"

If I add data it creates the index files. I can see them being created in the file system. All good from that end.

Here is my search code in a view:

num_posts = min(request.args.get('limit', 10), 50)
query = request.args.get('q', '')
results = Org.query.search(query, limit=num_posts)

It's returning AttributeError: 'BaseQuery' object has no attribute 'search'

I've done a heap of searching but am coming up empty. Can you spot what the issue is?

Thank you

Flask_whooshalchemy3 not indexing entries in blueprints

I have no problem when using flask_whooshalchemy3 without blueprints but with blueprints and factory function, either the indexes were not created or created but never searched.

Without Blueprint: Here is a portion of the view file, I called the flask_whooshalchemy3 search method in the before_first_request decorator.

from datetime import datetime
import json
import flask_whooshalchemy

from flask import render_template, request, abort, redirect, \
    url_for, flash
from werkzeug.urls import url_parse
from flask_security import Security, SQLAlchemyUserDatastore, \
    utils, login_required, login_user, logout_user, current_user
from flask_admin import Admin

from . import app
from .models import Article, Tag, db, User, Role, articles_tags, \
                    ArticleAdmin, TagAdmin, UserAdmin, RoleAdmin
from .forms import ArticleForm, LoginForm, RegistrationForm
from .utilities import split_article, update_article, can_edit
# ----------- Initializations----------------------------------
# Initialize the SQLAlchemy data store.
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
# Initialize Flask-Security.
Security(app, user_datastore)

# Executes before the first request is processed.
@app.before_first_request
def before_first_request():

    # Create any database tables that don't exist yet.
    db.create_all()
    # Indexing of articles to be search ready
    flask_whooshalchemy.search_index(app, Article)

With Blueprint: I called the search method in the app factory

from flask import Flask
from flask_admin import Admin
import flask_whooshalchemy
from flask_fileupload import FlaskFileUpload
from models import Article, Tag, db, User, Role, ArticleAdmin, \
                    TagAdmin, UserAdmin, RoleAdmin
from config import config

def create_app(config_name):
    app=Flask(__name__)
    app.config.from_object(config[config_name])
    db.init_app(app)
    db.reflect(app=app)
    # Initialize Flask-FileUpload.
    FlaskFileUpload(app)
    flask_whooshalchemy.search_index(app, Article)
    # Initialize Flask-Admin.
    admin = Admin(app)
    admin.add_view(ArticleAdmin(Article, db.session))
    admin.add_view(TagAdmin(Tag, db.session))
    admin.add_view(UserAdmin(User, db.session))
    admin.add_view(RoleAdmin(Role, db.session))
    # ----------- Initializations----------------------------------
    # Initialize the SQLAlchemy data store.
    from flask_security import Security, SQLAlchemyUserDatastore
    user_datastore = SQLAlchemyUserDatastore(db, User, Role)
    # Initialize Flask-Security.
    Security(app, user_datastore)
    from equimolar_blog.main_app import create_module
    with app.app_context():
        # Time to make sure roles exist in the database
        db.create_all()
        try:
            from create_db import create_roles
            create_roles(user_datastore, db)
        except ImportError:
            pass
        create_module(app)
    return app

I can't seem to point-out where the problem is.
