Rendering rich text
Brightspot stores rich-text elements as Strings, and a view model's getter for a String retrieves the text as it is stored. If Mary says to Henry in plain text, "No, Henry, I simply will not marry you!", Brightspot stores her refusal as:
and the view renders it the same way.
However, if Mary wants to put some emphasis into her refusal, she may say,
To render the previous string with boldface and italics, Brightspot needs to store HTML markup along with the plain text as in the following example:
However, Brightspot returns strings as they are stored. If you apply a simple getter to the above string, Brightspot escapes the opening and closing brackets so they appear in the rendered page. Looking at the rendered string's source, you see all the escape codes.
Brightspot provides the RichTextViewBuilder class to revert the escaped HTML to unescaped HTML so that the browser renders the rich text as expected.
Step 1: Create a rich-text marker
Create a rich-text marker interface RichTextElementView
.
public interface RichTextElementView {
}
Brightspot uses implementations of this interface to create views.
Step 2: Add rich-text support to view model
Apply the method RichTextViewBuilder#buildHtml
to the escaped HTML.
import com.psddev.cms.rte.RichTextViewBuilder;
import com.psddev.cms.view.ViewModel;
import com.psddev.cms.view.PageEntryView;
import styleguide.content.article.ArticleView;
public class ArticleViewModel extends ViewModel<Article> implements ArticleView, PageEntryView {
@Override
public CharSequence getBody() {
return RichTextViewBuilder.buildHtml(
model.getBody(),
e -> createView(RichTextElementView.class, e));
}
/* Other getters */
}
-
Retrieves the escaped HTML from the model.
-
Calls the method
createView
to convert the escaped HTML into a view using the marker classRichTextElementView
created in step 1.
