similar to: Blind effect and tables

Hi, What would my method call in an rjs template to produce something like: new Effect.BlindDown($(''commentList'').lastChild); I know if I just wanted to the blind effect I would: page.visual_effect :blind_down, "row_#{@new_item.id}" but how would I call it if I want the ".lastChild instead of passing a particular id? thanks, scott.

Hi, Has anyone gotten the "roughcuts" of the Ruby and Rails cookbooks? If you have the Pragmattic Rails Cookbook is the O''Reilly worth it? Also can you download PDF''s of their "roughcuts". The website is kind of vague, it just mentions online access (whatever that means). Thanks in advance.

Hi, I have been heck of a time to get mysql and fastcgi to work properly on my Mac OS X box.

Hi, I''m attempting to add a route via a plugin. I attempted to add the following to my init.rb: myroute = ActionController::Routing::Routes.connect "boo2", :controller=>''plugin'', :action=>''index'' puts "path=#{myroute.path}" myroute.options.keys.each do |k| puts "#{k}=#{myroute.options[k]}" end The newly

It looks rails automatically creates a "finder" method on models that have a "belongs_to". So I tried this in the console: c = Category.find(2) chunks = Chunk.find_by_category(c) chunks is always returned as an empty array. When I know have some chunks with a category_id of 2. Should the find_by_category do what I think it should be doing or am I completely off base?

I am teaching myself R for use in Psych research. I don't understand the error message I am getting or how to fix it.

Hello, I'm switching over from SAS to R and am having trouble merging data frames. The data frames have several columns with the same name, and each has a different number of rows. Some of the values are missing from cells with the same column names in each data frame. I had hoped that when I merged the dataframes, every column with the same name would be merged, with the value in a complete

Hi, I''m attempting to migrate an app from Apache+FCGI to Apache+Mongrel. I''m using Apache 2.0 with the latest Mongrel release. I''m having an issue with the Mint stats package and Mongrel not picking up the following url: /mint/?js Basically inside the /mint folder there is an index.php, so the url /mint/?js should really be going to /mint/index.php?js When I had my

Hi, First of all I love Mongrel and I want to say thanks! My questions are related to how things work compared to Apache+FCGI background 1. With FCGI I would normally setup multiple FGI processes do I need to setup multiple Mongrel processes? Or is Mongrel thread based? Does the --num-procs flag work the same way? 2. Is there one database connection per process? Thanks in advance.

Hi, I don''t know if this question should be posted here on the Rails list or the Mongrel list, but I''ll try here first.

Hello, I have two data frames. One is my dependent variable and the other is my independent variable. For each row I'd like to split the independent variable into fractiles (25 or more) and calculate the average value of the dependent variable. Then I would like to plot the average of the averages for each row for each fractile. If possible, I'd like to have the option to 1) define the

Hi, I''m using the new acts_as_taggable on Rails 1.1.1. I would like to get a list of all the tags for a particular model type, in my case "Post". I got it to work with: Tag.find(:all,:include => :taggings, :conditions => "taggable_type=''Chunk''") But I''m wondering if there''s a more Rubyish elegant way. thanks, scott.

A couple of quick acts_as_taggable (the Rails 1.1 plugin version) 1. Can you update tags on an existing record? If I execute the tag_with statement twice it creates two rows in the taggings column, instead of updating the value of the existing tag 2. Can you delete tags? I didn''t see a method for this. If I can delete tags, problem #1 goes away. scott.

Is there away to have parts of a migration file only work with a specific database. For example I am inserting some data into a table with: execute "INSERT INTO demo_lists(position, name, updated_at, created_at) VALUES (1, 1, ''scott'', CURDATE(), CURDATE());" Of course the curdate() function may only be available on mysql. So can we some how determine which
