I know this is a silly question, but I am just wondering when making the
link between children and the parent table, for example a blog reply, is
there a "best practice" way of doing this.
The only way that I can think of is to create a hidden input field
within <form>
ex, <input type="hidden" id="post_id" value="1"
/> (of course do it the
ruby way).
Is this the only way?
Thanks for the help
<% form_for :url => {:action => "create_reply"} %>
<%= form.hidden_field :post_id %>
<%= form.text_field :title, :size => 30 %>
<%= form.text_area :content, :cols => 40, :rows => 5 %.\>
<%= submit_tag "Post", :class => "submit" %>
<% end %>

Normally, one would use:
<% form_for :url => {:action => "create_reply", :id =>
@posts} %>
This generates something like:
<form method="post"
action="/controller/create_reply/3">
So, the actual post id is buried in the url to which you will issue your
POST request.

Thanks for the reply. I thought that doing it that way embeds the :id value into the params hash table through the id key ex, params[:id] Do you then have make the following setting manually? params[:post_id] = params[:id] Steve Ross wrote:> Normally, one would use: > > <% form_for :url => {:action => "create_reply", :id => @posts} %> > > This generates something like: > > <form method="post" action="/controller/create_reply/3"> > > So, the actual post id is buried in the url to which you will issue your > POST request. >-- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

two ways to do what u want to do:
a) hidden field. you suggested this above.
b) via the controller when passing the id in :id => x ; but instead of
params[:post_id] = params[:id]
do
@reply.post_id = params[:id].to_i # the to_i isn''t really that
neccessary

That make sense. I guess I thought rails would have it''s own way of
doing this.
The only other thing that I am wondering about is whether the
params[:id] value must be cleared out to prevent the save method from
thinking that the attempted insert is actually an update. I will have
to check this out after work.
Thanks for all the help.
<% form_for :reply, :url => {:action =>
''create_reply''} do |form| %>
...
<% end %>
////
def create_reply
params[:post_id] = params[:id]
params[:id] = nil
post = Post.new(params[:reply])
post.save
end
