hello,

I have a field in the DB called phone\_number , string 10 chars. In  
my form i want to make these 3 text boxes (phone1, phone2, phone3). I  
am trying to figure out how to assemble this to create the phone  
number before saving. I am trying the following:

In the model

before\_save :make\_phone

def phone1  
end

def phone2  
end

def phone3  
end

def phone1=(p1)  
end

def phone2=(p2)  
end

def phone3=(p3)  
end

def make\_phone  
self.phone\_number = phone1 + phone2 + phon3  
end

however i dont seem to have access to params[:model][:phone1] from  
here. Any ideas on how to make this work ?

Thanks

Hi, what does your param hash look like when you submit the form?

Your attribute writer methods don’t do anything at the moment. They’ll  
have to set instance variables which can be accessed by the  
before\_save method. The attr\_accessor shortcut can provide these.

You’re looking for something like:

before\_save :make\_phone  
attr\_accessor :phone\_1, :phone\_2, :phone\_3

def make\_phone  
self.phone\_number = @phone\_1 + @phone\_2 + @phone\_3  
end

And you may be able to streamline this a bit with composed\_of.
