Hi ppl.

I am noob in rails and started an app to learn. I have the following  
scenario:

table client with fileds: name, second\_name  
table phone with fields: number, client\_id  
table address with fields: street, number, client\_id

The migrations worked ok and the fields are created.

Now i defined in the model that

for client:  
has\_many :phones  
has\_many :adresses

for phones and adresses:  
belongs\_to :client

I made a form to get some of these fields and add to the database:

\<% form\_for(:clients) do |f| %\>

**Name** \<%= f.text\_field :name %\>

**Second Name** \<%= f.text\_field :second\_name%\>

**Number** \<%= f.text\_field :number%\>

\<%= f.submit "Add" %\>

\<% end %\>

And in the controller i try to save it to the DB:

@clients = Clients.new(params[:clients])  
@clients.save

When i submit i get an error saying that number is not a method, it  
means it  
didnt associate number with a cliente. It’s not “joining” the tables.

Where did i made a mistake here?

Thanks guys.

1. Try asking this questions in rail snewsgroup
2. You are trying to access field from other table. The right way to  
access the filed would be:  
client.phones[n].number

and I don’t know if this can be done with simple form.

Oh, it’s true, i always end up mixing up rails list with ruby list!

Thanks for the tips though 🙂
