Using Translations ​

This guide explains how to use translations to build multilingual forms without duplicating your form structure. You define a set of key/value pairs per culture, and Rulecube automatically substitutes the correct text based on the active culture when the form is rendered.

How it works ​

  • Every element Label in a form doubles as a translation key
  • When a culture is active, Rulecube looks up the label text in the translation table for that culture
  • If no translation is found, the original label text is used as a fallback

Adding translations ​

  1. Open your form in the editor
  2. Go to the Translations tab
  3. Click + Add Language
  4. A matrix view opens — rows are translation keys, columns are cultures
  5. Enter the translated value for each key in the relevant culture column

Tip: Leave the default (English) column blank — Rulecube uses the label text itself as the English value.

Two approaches to keys ​

Approach 1 — Use natural labels as keys (simple) ​

Set element labels to plain text, e.g. First name. Then add a translation row with the same key and provide the Dutch value Voornaam.

  • Pro: Simple and readable in the editor
  • Con: Renaming a label breaks the translation link (key and label must stay in sync)

Set element labels to uppercase identifiers, e.g. FIRST_NAME. Then provide translations for all cultures, including English (First name) and Dutch (Voornaam).

  • Pro: Renaming the displayed text only requires updating the translation table, not the element label
  • Con: Labels look technical in the form editor

Example ​

  1. Add a new Form to the Ruleset
  2. Go to the tab Translations
  3. Click + Add Language, a table appears
  4. Click + Add Language and select nl-NL
  5. Add a new Key with:
    1. Key: First input
    2. en: (empty — uses label)
    3. nl-NL: Eerste invoer
  6. Go to the tab Definition
  7. Create a new Input
    1. Label: First input
    2. Property binding: Manual, Path: a
  8. Save the Ruleset

Previewing the Form ​

  1. Click the Preview button in the top right corner

When clicking on the nl-NL culture, the label renders as Eerste invoer.

Switching cultures ​

The active culture is determined by the context in which the form is embedded (e.g. the browser language or a workspace setting). You do not need to add any logic to the form itself — Rulecube handles the lookup automatically.

Tips ​

  • Translations apply to labels only — dynamic content (e.g. values returned by a ruleset) must be translated in the ruleset itself if needed
  • The matrix view is the easiest way to manage translations across many cultures at once
  • Unused translation keys (keys with no matching label) are ignored — clean them up periodically to keep the table readable
