WTForms is a flexible forms validation and rendering library for python web development.
To get started using WTForms, we recommend reading the crash course on the docs site: https://wtforms.readthedocs.io/en/stable/
If you downloaded the package from PyPI, there will also be a prebuilt copy of the html documentation in the docs/html/ directory.
- Security-first design; we take good validation seriously.
- Framework-agnostic; works with your web framework and template engine of choice.
- Rich ecosystem of library integrations
The easiest way to install WTForms is using pip:
pip install WTForms
If you downloaded a source tarball, or cloned the repository, you can install using setup.py:
python setup.py install
You can also simply place the wtforms subdirectory somewhere on your python path. This can be useful if you deploy on Google App Engine for example.
WTForms works with most web frameworks very well; but there are a number of tools available that make integration with database ORM's, environments, and frameworks even better - either reducing boilerplate or adding features like query fields, etc.
- Flask-WTF is an integration with the Flask framework providing a solid default CSRF configuration, file upload support, flask-i18n integration, and more.
- WTForms-Appengine provides ORM-backed fields and form generation from Appengine db/ndb schema
- WTForms-SQLAlchemy provides ORM-backed fields and generation of forms from models.
- WTForms-Alchemy provides powerful model forms support
