Hi,

I have this class called Myfile (cause file is a reserved word), when a  
validation of a field in this class fails the error message shows: “1  
error prohibited this myfile from being saved”, of course I just want it  
to say file instead of myfile. However… I don’t have a clue how to do  
this.

Any ideas???

Thanks,  
Mischa.

OK, I’m getting around it like this now:

\<% err = error\_messages\_for(“myfile”) %\>  
\<% if err %\>  
\<%= err.sub!(“myfile”, “file”) %\>  
\<% end %\>

But there must be any another way. Help!

Grt,  
Mischa

</div>

another (shorter) way:  
\<% err = ((a=error\_messages\_for(“myfile”)).nil? ? nil : a.sub(“myfile”,  
“file”)) %\>

better yet, you could create a new function in a helper to perform the  
transform:

def myfile2file(s)  
return if s.blank?  
s.sub “myfile”, “file”  
end

\<% err = myfile2file(error\_messages\_for(“myfile”)) %\>

Thanks. Why didn’t think of that myself? In the end I implemented it  
like this:

def myfile\_to\_file(msg)  
msg.sub(“myfile”, “file”) if msg  
end

\<%= myfile\_to\_file(error\_messages\_for(“myfile”)) %\>
