Overview of Rasa Forms

Rasa Forms are an essential component of chatbot development, enabling the collection and utilization of user-provided information. Forms automate the process of gathering specific information by asking users predefined questions and storing their responses as slots. This information can then be utilized in custom actions during conversations. The structure of Rasa Forms follows a loop, where questions are asked until all slots are filled, and a custom action is triggered. The visual representation of Rasa Forms resembles a flowchart, illustrating the user's Journey through the form.

Customizing Rasa Forms

Dealing with Unhappy Paths

Unhappy paths refer to situations where a user's behavior deviates from expected actions. While unhappy paths are not inherently negative, they require customization to ensure smooth interactions. Validators can be used to ensure the correctness of user-provided information. Additionally, it is essential to consider conversational aspects such as topic changes, interruptions, or requests to cancel the form. By customizing the form, you can account for these common unhappy paths and provide a more robust and user-friendly experience.

Handling Interruptions

Interruptions can occur when users, while actively engaged in a form, pause to ask questions unrelated to the form. As chatbots aim to mimic human conversation, it is crucial to acknowledge and address these interruptions appropriately. By configuring an extra rule, interactions unrelated to the form can be handled seamlessly. Once the interruption is addressed, the form conversation seamlessly resumes.

Cancelling a Form

There may be instances where a user decides to cancel a form before submitting all the required information. Rather than automatically submitting an incomplete form, it is beneficial to confirm the user's intent to cancel and provide a conversational design that incorporates a user's change of mind. By configuring a story instead of a rule, the form can be canceled before submission, ensuring a smooth and intuitive user experience.

Preventing Unhappy Paths

While customization allows for handling unhappy paths, it is essential to consider strategies that prevent them altogether. By employing the use of buttons, user feedback can be facilitated, simplifying the interaction process. Buttons provide users with predefined options, reducing the need for open-ended responses. This not only prevents deviations from expected behavior but also enhances the user experience through increased speed and convenience.

Enhancing the Happy Path

Apart from addressing unhappy paths, customization can also enhance the happy path. By providing additional questions or options dynamically, the form can be personalized and tailored to the user's preferences. This can be achieved by using custom actions to generate buttons that allow users to make selections rather than typing responses. Enhancing the happy path not only improves user satisfaction but also streamlines the conversation flow.
