I''m a newbie in Rails and I''m follwing some tutorials right
now.
Right now, I''m following "Creating a weblog in 15 minutes"
that posted
on rubyonrails.org site, but there is onething that I don''t understand.
According to the demo movie, when posting a comment under a blog entry,
write following codes:
def add_comment
Post.find(params[:id]).comments.create(params[:comment])
flash[:notice] = "Added your comment."
end
and then in the view file,
<%= start_form_tag :action => ''comment'', :id => @post
%>
<%= text_area ''comment'', ''body''
%><br />
<%= submit_tag ''Comment!'' %>
<% end_form_tag %>
What I don''t understand is, if we have more column in the comment
table,
for example ''comment_poster_id'' or
''commented_time'', then where do I
assign the value?
Logically, I think it should be within the controller file, not in the
view file, but I don''t know how.
Could you someone tell me how can I do that? Thanks :)

The create() method takes in a hash containing keys names the same as fields
in the respresentative table. In this case, you''ll probably be passing
in:
params = { :post => { :id => [postid] }, { :comment => { :body =>
''some body
text'' } }
Thus, you can just modify the poster form to include a comment_poster_id
field which will automatically be added into the hash for you.
However if you need to add such values in the Controller, you can do this:
def add_comment
comm = Comment.new(params[:comment])
comm.poster_id = poster_id
comm.commented_time = Date.today # or whatever
Post.find(params[:id]).comments << comm # I think this saves for you
but
I can''t remember.
end
There are many different ways of manipulating ActiveRecord objects. If in
doubt, just seperate out into seperate objects and do what you need.
Hope that helps.

For comm.commented_time, you can use ActiveRecord''s "magic" created_at column, which will default to the time the Record is created without you having to do anything. Just call the column "created_at" and make sure it can handle a timestamp (string works at worst.)
