What is a translation key?

Translation keys refer to the strings in your application. Translation key can be a word, a phrase, a sentence or even a paragraph.

We do recommend to keep translation keys concise and break the paragraphs into sentences, unless they must be together.

For example, all of the following elements are translation keys:


tr("Name")

tr("Hello World")

tr("Welcome to Translation Exchange")

<%= tr do %>
  An entire paragraph can be wrapped into the translate function. Unless you specify that you want to break the paragraph into sentences, all of the sentences will be kept together as a single translation key.
<% end %>
