Hi,  
Any one please help to me solve the problem in  
text\_field\_with\_auto\_complete.

I want to call the auto\_complete AJAX function only after i enter 4  
characters.  
To do this i have included the “min\_chars” option.

My code is

\<%= text\_field\_with\_auto\_complete :detail, :title, {:min\_chars =\> 4} %\>

But this is not working .

Am i doing any mistakes? Pls. help me!!!

The signature of the helper is

text\_field\_with\_auto\_complete(object, method, tag\_options = {},  
completion\_options = {})

So you need to put an explicit empty tag\_options this way:

\<%# untested %\>  
\<%= text\_field\_with\_auto\_complete :detail, :title, {}, :min\_chars =\> 4  
%\>
