FormAlchemy

FormAlchemy greatly speeds development with SQLAlchemy mapped classes (models) in a HTML forms environment. It eliminates boilerplate by autogenerating HTML input fields from a given model. FormAlchemy will try to figure out what kind of HTML code should be returned by introspecting the model's properties and generate ready-to-use HTML code that will fit the developer's application.

Of course, FormAlchemy can't figure out everything, i.e, the developer might want to display only a few columns from the given model. Thus, FormAlchemy is also highly customizable.

Features:

• Generates HTML form fields and tables from SQLAlchemy mapped classes or manually added Fields
• Works with declarative or classic mapper definitions
• Render and edits single objects or collections (grids)
• Handles object relationships (including many-to-many), not just simple data types
• Synonym support
• Composite and custom type support
• Supports all composite primary keys and most CFKs
• Pre-fills input fields with current or default value
• Highly customizable HTML output
• Validates input and displays errors in-line
• Syncs model instances with input data
• Easy-to-use, extensible API
• SQLAlchemy 0.4 (0.4.5 or later) and 0.5 compatible
