Thymeleaf custom dialect with fragments
In my Spring Boot 2 project I have Thymeleaf fragments to generate form elements. For example:
<input th:replace="component/admin_form :: text (formElement = ${vm.getElementStatus()}, class='css-class-a'))" />
The code above generates a complex div block with label, input field and error block.
I would like to simplify this syntax. My idea was to create a custom dialect with a custom tag and write this:
<admin-form:text value="${vm.getElementLastName()}" class="css-class-a"/>
The second one is easier to read, it clearly indicates for the designers that this is a special element. Besides this, it would be easier to change themes as I only need to change the concrete fragment location in the tag processor and not hundreds of th:replace value.
It is also important that I don't want to build the complex html layout in the tag processor just want to somehow import a fragment. So designers can modify the html fragment without java code changes.
I was able to create the custom dialect and create the custom tag that generates a html block:
@Override
protected void doProcess(ITemplateContext context, IProcessableElementTag tag, IElementTagStructureHandler structureHandler) {
final IModelFactory modelFactory = context.getModelFactory();
final IModel model = modelFactory.createModel();
model.add(modelFactory.createOpenElementTag("div", "class", "test"));
model.add(modelFactory.createText("This is my custom element"));
model.add(modelFactory.createCloseElementTag("div"));
structureHandler.replaceWith(model, false);
}
But I don't know how to import a fragment in my custom tag.
Is it possible anyhow?
