Changing text based on the final letter of user name

In my system, users will register their names. In the natural language the system is used with, names end differently depending its use, such as:

Due to this, I need to change the ending of @provider_user.name in some places; if it ends with e, replace e with ai.

My HTML slim code is:

= render partial: 'services/partials/messages/original_message', locals: { header: t('html.text.consultation_with.for_provider', name: @provider_user.name)

It takes text from a yml file and uses @provider_user.name.

Any suggestions to work this around?

It's really easy, that's why I love Ruby...

class String
    def replace_ends(replace, with) 
        end_array = self.split " "
        end_array.map! do |var|
            break unless var.end_with? replace
            var.chomp(" ").chomp(replace) + with
        end
        return end_array.join " "
    end
end

Try this, simple single line code

@provider_user.name.split.map {|w| (w.end_with?('e') ? (w.chomp(w[w.length - 1]) + 'ai') : w) }.join(" ")

I am sure, it will convert "name surname" to "namai surnamai".

In additional cases...

@provider_user.name.split.map {|w| (w.end_with?('e') ? (w.chomp(w[w.length - 1]) + 'ai') : (w.end_with?('us') ? (w.chomp(w[w.length - 1]) + 'mi') : (w.end_with?('i') ? (w.chomp(w[w.length - 1]) + 'as') : w))) }.join(" ")

"name surname".gsub(/e\b/, 'ai') # "namai surnamai"

.gsub uses a regular expression to search and replace in a string. Its the greedy version of .sub meaning that it will replace all occurrences.

\b matches any word boundry.
