I was playing around with: [http://strawr.googlecode.com/svn/trunk/app/views/feeds/show.rhtml](http://strawr.googlecode.com/svn/trunk/app/views/feeds/show.rhtml) and changed a few things so that it’s like so: thufir@arrakis ~/strawr $ thufir@arrakis ~/strawr $ cat app/views/feeds/show.rhtml -n | head -n 47 | tail -n 10 38 39 \<% @unused\_tags = Tag.find(:all) - @feed.tags %\> 40 \<% if @unused\_tags.any? %\> 41 \<% form\_for :tag, @tag, :url =\> { :action =\> “create” } do | f| %\> 42 \<%= f.text\_field :tag %\> 43 \<%= submit\_tag ‘Create’ %\> 44 \<% end %\> 45 \<% end %\> 46 47 thufir@arrakis ~/strawr $ However, what does the above actually _do_? Here’s output from “script/ server mongrel”: Processing FeedsController#create (for 127.0.0.1 at 2008-01-24 01:16:37) [POST] Session ID: 98ae0df6837d8c491cfd58ecfee7c744 Parameters: {“commit”=\>“Create”, “tag”=\>{“tag”=\>“is this a tag or feed? should be tag…”}, “action”=\>“create”, “controller”=\>“feeds”} Feed Columns (0.012260) SHOW FIELDS FROM feeds SQL (0.008202) BEGIN SQL (0.012374) INSERT INTO feeds (`feed`) VALUES(NULL) SQL (0.027005) COMMIT Redirected to [http://localhost:3000/feeds/list](http://localhost:3000/feeds/list) Completed in 0.08288 (12 reqs/sec) | DB: 0.05984 (72%) | 302 Found [[http://localhost/feeds/create](http://localhost/feeds/create)] Processing FeedsController#list (for 127.0.0.1 at 2008-01-24 01:16:38) [GET] Session ID: 98ae0df6837d8c491cfd58ecfee7c744 Parameters: {“action”=\>“list”, “controller”=\>“feeds”} Feed Columns (0.007587) SHOW FIELDS FROM feeds SQL (0.000587) SELECT count(\*) AS count\_all FROM feeds Feed Load (0.000567) SELECT \* FROM feeds LIMIT 0, 10 Rendering within layouts/feeds Rendering feeds/list Completed in 0.04696 (21 reqs/sec) | Rendering: 0.01785 (38%) | DB: 0.00874 (18%) | 200 OK [[http://localhost/feeds/list](http://localhost/feeds/list)] \*\* INT signal received. Exiting thufir@arrakis ~/strawr $ where it loks to be inserting a null value into the feeds table, yes? This is interesting, as it’s close to what I want, which would be inserting data into tags and _also_ the join table, memberships. However, it’s inserting data, which is progress 🙂 So, I haven’t commited this to the svn repository (I need to practice branching for stuff like this), but it’s certainly intriguing. -Thufir
