Tools for creating WTForms forms from SQLAlchemy models (library)

WTForms-Alchemy provides a helper class that let you create a Form class from a SQLAlchemy model. It does not try to replace all the functionality of wtforms.ext.sqlalchemy, only the model_form function of wtforms.ext.sqlalchemy by a much better solution. Other functionality of ext.sqlalchemy such as QuerySelectField and QuerySelectMultipleField can be used along with WTForms-Alchemy.

The benefits of WTForms-Alchemy ModelForm over wtforms.ext.sqlachemy’s model_form include:

 * Provides explicit declaration of ModelForms (much easier to override
   certain columns)
 * Form generation supports Unique and NumberRange validators
 * Form inheritance support (along with form configuration inheritance)
 * Automatic SelectField type coercing based on underlying column type
 * By default uses wtforms_components SelectField for fields with choices.
   This field understands None values and renders nested datastructures as
   optgroups.
 * Provides better Unique validator
 * Supports custom user defined types as well as type decorators
 * Supports SQLAlchemy-Utils datatypes
 * Supports ModelForm model relations population
 * Smarter field exclusion
 * Smarter field conversion
 * Understands join table inheritance
 * Better configuration
