The simple, quick and easy generative web framework for python

Pow logo

PythonOnWheels reStructured and reImplemented.

I call it SQUEEZY => for Simple, Quick and Easy.

Principle

> Designed for simplicity, happiness and Quick results!

As simple to use as possible. Everything you always need on board. Batteries included! (tornado Webserver, SQLite DB, NoSQL DBs: tinyDB, MongoDB, MongoDB Atlas Service) Non intrusive! You can always escape and go RAW.

Newly implemented:

• MongoDB support (Transactions usable with Mongo >4)

• MongoDB Atlas support for even quicker start in the cloud

• Observer for Models (Like ActiveRedcord. Just add a class Named: ModelNameObserver. Will be found and used by convention)

• Added Dirty Model support (like ActiveRecord). Track changes, Show, rollback.

Strong Foundation:

• python 3.x

• tornado webserver

• sqlalchemy ORM onboard (sqlite, mysql, postgres, oralce, ms-sql …)

• DB migrations generated for you (based on alembic)

• cerberus schemas and validation on board

• template engine (tornado templates)

• Many SQL DBs[sqlite, mysql, postgres, ms-sql,orcale ] NoSql DBs: tinyDB, MongoDB and ElasticSearch on board…

• authentication with Twitter, Google on board

Super easy, quick to start and all the basics on board:

• super easy relations with decorators @relations.has_many(“comments”)

• super easy REST routing with decorators @app.add_restful_routes(),

• routing decorator @app.add_route(route)

• db migrations autogenerated using alembic in the back

• validation on board with cerberus schemas

• use the same schema descrition for all model types (sql, nosql, elastic..)

• generate_models script

• generate_migrations script

• update_db script

• generate_handlers

• generate_app

• automatic scaffolding views (work in progress)

Code examples

Routes:

# You can use regex routes
# this will call the myget method on HTTP GET calls and will hand over the re-group as the 1st parameter.
@app.add_route("/index/([0-9]+)*", dispatch={"get" : "myget"})
# Or you can also use Flask/Werkzeug routes
@app.add_route('/index/<int:year>', dispatch={"get" : "myyear"})
class IndexdHandler(BaseHandler):
    def myget(self, index=None):
        print("  index:" + str(index))
        self.render("index.tmpl")

    def myyear(self, year=None):
        self.write("I got year: " + str(year))

Relations: (SQL Models)

@relation.has_many("comments")
class Post(Base):
    # a blog Post
    schema = {
        'text'      : {'type': 'string'},
        'name'      : {'type': 'string', 'maxlength' : 35},
        'votes'     : {'type': 'integer'},
        'status'    : {'type': 'string', 'allowed' : ['ready to publish', 'needs review', 'draft'] },
        'published' : {'type': 'boolean', 'default' : False }

    }

NoSQL Models

class Post(Base):
    # a blog Post
    schema = {
        'text'      : {'type': 'string'},
        'name'      : {'type': 'string', 'maxlength' : 35},
        'votes'     : {'type': 'integer'},
        'status'    : {'type': 'string', 'allowed' : ['ready to publish', 'needs review', 'draft'] },
        'published' : {'type': 'boolean', 'default' : False },
        'tags'      : {'type': 'list', 'default' : [] }

    }

Hope you see that SQL and NoSQL are pretty much the same. No need for relations in NoSQL. But you have enhanced datatypes like lists and dicts in NoSQL. A NoSql List can be mapped to a SQL @relation.has_many() ….

Enjoy!
