Rasa MetForm is a small extension of [Rasa](https://rasa.com)'s [`rasa-sdk`](https://github.com/RasaHQ/rasa-sdk) which introduces a `MetaFormAction`, an extended `FormAction`. Read more in a [blog post](https://medium.com/magnetcoop/rasa-metaform-df9ca99076f3).

## Problem statement

### Forms

Creating Forms in Rasa requires defining a class for each form, inheriting from `FormAction`, specifying few methods, as well as in `domain.yml`, with matching slots and templates.

### Ideal

Form would be specified in a single, human-readable, easy to edit file. From this file we would populate `domain.yml` with all the necessary instances of `forms`, `slots` and `templates`, as well as define a new `FormAction` class, which will implement all the necessary methods, including `name`, `required_slots` (following the logic in the form file), `slot_mappings`, all `validate_{slot}` and `submit`.

### Proposal

`MetaFormAction` allows to create classes from a YAML file and populates the domain with all the needed information.

## Installation

The easiest way to install the package is through [PyPI](https://pypi.org/project/rasa-metaform).

```sh
pip install rasa-metaform
```

However you might find it more useful to clone the repository and edit the `MetaFormAction` class for your form(s). We will extend the functionality with additional validation methods.

## Form YAML file

See the [`sample.yml`](https://github.com/magnetcoop/rasa-metaform/blob/master/tests/sample.yml) for an example form YAML file.
