Hey all,
trying to get a concept down. Or maybe the syntax.
Here is the code:
<p>Phones</p>
<p><% @person.phones.each { |phone| %>
<%= tag("input", "type" => "text", "id" =>
"phones[#{phone.id}][phone]", "name" => "phones[#{phone.id}][phone]",
"value" => phone.phone) %>
<%= phone.errors.on "phone" %><br/>
<% } %></p>
<p>Add new phone: (More phones can be added later)<br />
<input type="text" id="phones[new][phone]" name="phones[new][phone]"
value="">
</p>
What, exactly, is the [phone] in phones[#{phone.id][phone]? I know
phones is the db phones. I know phone id is the PK (and for
phones[new][phone]. What is phone though? Also, in phones[new][phone],
what is new creating/doing?
Similarly:
def update
@person = Person.find(@params["person"]["id"])
@person.attributes = @params["person"]
if @person.save
redirect_to :action => "show", :id => @person.id
else
render "person/edit"
end
end
What is ["person"]? What is it referencing?
Thanks.
