Dear readers, I am puzzles by the following, imagine models A and B. A has_one B and B belongs_to A. So far so good. But rails does this great thing by relfecting on this relationship and enables me use the equals sign to do A.B=B. But now comes the puzzlement. Whenever you do this B is supposed to be saved (see, http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html#M000472). Now a couple of questions, where do the errors go if one implemented a validate method? I guess nowhere and they are ignored. Moreover if you use ''validates_associated :B'', which makes sense, you are forced to use the equals sign method, which supposedly already saves the model (which it actually doesn''t, I checked). So when is a instantiation of a model really saved? With kind regards, Harm -- Posted via http://www.ruby-forum.com/.
Hello all, Excuse me if I''ve got my terms incorrect (please correct me if so!). I''ve created a partial for this blog application I''m writing, which contains the following <h2><%= link_to post.title, :action => ''show'', :id => post.title %></h2> <h4>Posted on <%= post.created_on.strftime("%d %b %Y @ %H:%M") %> by Alastair</h4> <div><%= post.body %></div> <p> <span id="tags"><% for tag in post.tags.split(" ") %> <%= link_to tag, :action => ''find'', :id => tag %><% end %> tags</span>| <span id="tags"><%= link_to post.comments(:refresh).size, :action => ''show'', :id => post.title, :anchor => "comments" %> comments</span> </p> What I would like to do is depending on which action was called, write out different code. So if the action was list or index, then write out <h2><%= link_to post.title, :action => ''show'', :id => post.title %></h2> otherwise <h2><%= post.title %></h2> Simple but not knowing the ruby/rails terms, I''m struggling to find the right search term in google! Thanks in advance, Alastair

So I''m going to tinker around with that and see what I come up with! Alastair
