Business logic masterclass Day 1: Form rules
Master building business logic with our visual rule builder, no coding required. In this first session of our free 4-part masterclass, we will walk you through the building blocks of logic creation, including core rule types, behaviors, and tools to create intelligent mobile experiences.
What you’ll learn:
- What business logic means in mobile business apps and how Resco enables it
- Intro to rules editor and rules in general
- Form rules: the purpose and usage of
onload
,onchange
, andonsave
rules - Practical examples, including:
onload
: how to handle the fact each field loads only once, and how to cover the opposite when setting a value, hiding field, or state for field due to reuse formonchange
: how to prevent unnecessary rule execution withChangedItem
, howIsLoaded
helps isolate user-driven changes, and how to use validation for setting styles (e.g. error colors) dynamicallyonsave
: what to keep in mind to prevent stopping the form saving process
- The shared variable concept, how to use it to move values across rules and JavaScript, and what to keep in mind when using it as entity load
- Using Say Text for debugging logic flows and testing results
- How to use the new instance variable to create records in background
Whether you’re building forms for sales, inspections, or field service, this session will give you a solid foundation in rule-based logic: powerful, offline-ready, and code-free.
