Attribute Accessors for Phone Number in Form

Rails
1

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.
