I have a single form that can be used for multiple models, in my view i  
origionally had “Add a New #{@element.class}” how can i write a dynamic  
i18n translate call?

I want to do something like

\<%= t ‘removed\_email\_address@domain.invalid’%\>

What is the best way to accomplish this functionality?

</div>

figured it out…

\<% type\_of\_element = @element.class.to\_s.downcase %\>  
\<% add\_element\_to\_translate =  
[“model”, “add”, type\_of\_element  
].compact.join(‘.’)%\>  
\<%= t add\_element\_to\_translate %\>

hopes this helps someone else, if you figure out a better way let me  
know!!
