This repository contains a collection of tutorials that will help you understand forms. Each example is self contained and is part of a series of videos on our youtube channel. Note that all the demos here are built with Rasa 2.3 in mind. These examples won't work for Rasa 3.x onward.
To run all the examples here you'll need to install Rasa, preferably in a virtualenv in the root directory.
python -m pip install rasa==2.3
If you'd also like to use Rasa X, you can install this via;
python -m pip install rasa-x --upgrade -i https://pypi.rasa.com/simple

You can customise how questions are asked in a form. You can write templates in a domain.yml file or use custom actions.
What if we want to validate the input of our form? We don't want to have a name that's an empty string after all!
Code can be found in the 04-checking-form-input folder.
The user might give the response in a sentence, in which case we'll want to detect entities instead of grabbing the full text.
Code can be found in the 05-entities-and-forms folder.

In this final example we'll show an elaborate example of a form that can ask for names.
