#ctx.getModel()

Get any model instance in the current engine by model uid (e.g. BlockModel, PageModel, ActionModel). Use it to access other blocks/pages/actions from RunJS.

If you only need the model of the current context, prefer ctx.model or ctx.blockModel.

#Type definition

getModel<T extends FlowModel = FlowModel>(
  uid: string,
  searchInPreviousEngines?: boolean
): T | undefined

#Parameters

#Return value

• Returns a FlowModel subclass instance (e.g. BlockModel, PageModel) if found
• Returns undefined if not found

#Notes

• By default, it searches only within the current engine by uid. When searchInPreviousEngines: true, it searches the current engine and upstream engines (previousEngine chain), starting from the top of the stack.
• Useful when you need to access models across blocks/pages/modals by a known uid (e.g. get another block model and read/write its resource or form).

#Example

// Search only in current engine
const block = ctx.getModel('block-uid-xxx');
if (block) {
  console.log(block.uid, block.resource?.getData?.());
}

// Search in view stack (e.g. modal needs to access a page model)
const pageBlock = ctx.getModel('page-block-uid', true);
if (pageBlock) {
  pageBlock.rerender?.();
}

#Tips

• In JS Action / JS Field, use ctx.getModel for advanced control of other models.
• If you only need the current model or block, prefer ctx.model or ctx.blockModel.
