ModelName.find\_by\_name(‘some\_name’).  
I have a doubt with your table it should be replies rather than reply  
coz’ table name are plural form of model name in ROR (if you stick  
with convention over configuration).

Why don’t you try it out from your console. And if it work from there  
than you should have some problem in your controller.  
plz try it out from your console and let me know.
