Description
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
