flask-sqlalchemy

I'm trying to create a "modular application" in Flask using Blueprints. When creating models, however, I'm running into the problem of having to reference the app in order to get the db -object provided by Flask-SQLAlchemy. I'd like to be able to use some blueprints with more than one app (similar to how Django apps can be used), so this is not a good solution.* It's possible to do a switcharoo, and have the Blueprint create the db instance, which the app then imports together with the rest of the blueprint. But then, any other blueprint wishing to create models need to import from that

I am new in both flask and sqlalchemy, I just start working on a flask app, and I am using sqlalchemy for now. I was wondering if there is any significant benefit I can get from using flask-sqlalchemy vs sqlalchemy. I could not find enough motivations in http://packages.python.org/Flask-SQLAlchemy/index.html or maybe I did not understand the value!! I would appreciate your clarifications. The main feature of the Flask-SQLAlchemy is proper integration with Flask application - it creates and configures engine, connection and session and configures it to work with the Flask app. This setup is

I was trying to save a project's reviewer using below, and the select field shows correct: # Query the user with Role.id == 4 as reviewer def reviewer_choices(): return User.query.join(User.roles).filter(Role.id == 4) # Build a select field class ProjectView(sqla.ModelView): form_extra_fields = { 'reviewer': sqla.fields.QuerySelectField( label='Reviewer', query_factory=reviewer_choices, )} However, when I was trying to save it, the error occurred: InterfaceError: (sqlite3.InterfaceError) Error binding parameter 8 - probably unsupported type. [SQL: u'INSERT INTO project(...reviewer...)VALUES(..

I'm trying to create a Flask app that shows the latest score from individual players. So a player can have multiple scores, but on the leaderboard I only want to show her most recent score. My models.py: class Player(db.Model): __tablename__ = 'player' id = db.Column(db.Integer, primary_key=True) firstname = db.Column(db.String, nullable=False) score = db.relationship('Score', backref='player', lazy='dynamic') def __init__(self, firstname): self.firstname = firstname def __repr__(self): return '<id {}>'.format(self.id) class Score(db.Model): __tablename__ = 'score' id = db.Column(db.Integer,

I have a stored procedure on MSSQL server, "prc_add_names", that takes a table-value parameter. The parameter itself is of a custom type "StringTable" defined like so: CREATE TYPE [dbo].[StringTable] AS TABLE([strValue] [nvarchar](max) NULL) I have no idea how to execute this procedure using SQLAlchemy. I am used to calling procedures with arguments using session.execute like this: result = session.execute('prc_do_something :pArg', {pArg:'foo'}) However, this does not work if I simply pass a list of strings as the argument: result = session.execute('prc_add_names :pArg', {pArg: ['Name One',

I want to connect to a mysql server via flask and app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://your-username:your-password@localhost/schema' How can I add ca-cert, client-key and client-cert to the connection? Thomas N. You can add theses informations in your URI like this : app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://your-username:your-password@localhost/schema?ssl_key=MyCertFolder/client-key.pem&ssl_cert=MyCertFolder/client-cert.pem' Or using the SQLAlchemy create_engine, take a look to this post In case you need to use a Cloud-based MySQL service, this configuration will be
