...hing like 59 which fails my story because I''m asking it to look at /forums/1 I thought of using my named routes instead of specifying the path as a string. That worked up until the point when I reached: When "creating a new topic titled", "Nicks Mom" do |title| post topics(@forum, ??? ), :topic => { :title => title, :body => "She is teh hotZ!" } end The problem was since its a nested routed I couldn''t complete the post request without specifying the topic_id. But since the topic hasn''t been created yet their is no way (that I kno...

...t * Introduction and overview of LLVM * Topic links # Getting Started/Tutorials * Brief description w/topic links # Reference * Brief description w/topic links # Getting Involved/Community * Overview of how to get involved with the LLVM project * Topic links Due to the sheer number of topics, there would also need to be “sub-pages”. For example, there could be a separate Reference page that lists all of the available reference topics by category.

I have a User and Topic model. A user subscribes to a topic, so there is a many-to-many relationship between User and Topic. So my User model object is using has_many_and_belongs_to :topics and vice versa. I want to find all the topics that a user has *not* subscribed to. This is what I''ve got: @user = User.find(params[:id]) @topics = Topic.find(:all, :conditions => ["id not in (select topic_id from topics_users where user_id = ?)", @user.id]) I...

Hi, We are looking for new "Round Table" topics (i.e. mini-bof topics - formally known as hackers lab). The round table sessions are a great way for us all to discuss face-to-face any burning topics.

...help on a topic20 (in which case the present package has precedence so this is only needed to refer to other packages). They are only in used in HTML help (and ignored for hyperlinks in LaTeX conversions of help pages), and link to the file rather than the topic (since there is no way to know which topics are in which files in an uninstalled package). The *only* reason to use these forms for base and recommended packages is to force a reference to a package that might be further down the search path. Because they have been frequently misused, as from R 2.10.0 the HTML help system will look for topic...
