Why dosn''t the to first examples work as expected?? Do I have to put groups I don''t want to

Today I face with incorrect behavior in ActiveRecord. It take place when I try to use :include parameter for .find method. Where are two typical cases: 1. You have record with self-referential joins CREATE TABLE keywords (id, group_id); class Keyword < ActiveRecord::Base belongs_to :group, :class_name => "Keyword", :foreign_key =>

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),

I thought I had this nailed but.. now I''m seeing spots.. I''ve included my models below, feel free to ignore them. I''m really just after an example that works. I couldnt find one on the wiki... which is fair enough considering Ricks patch: http://dev.rubyonrails.org/changeset/4022 that fixed them only went through 5 days ago.. Cheers -henster

I have users who belong to a group. I also have a room that belongs to a group. I want to use a has_many through association to link the room and the users as such: class Room < ActiveRecord::Base belongs_to :group has_many :users, :through => :group end The SQL generated for the search is incorrect: SELECT users.* FROM users INNER JOIN group ON users.group_id = groups.id WHERE

So I can, for example, validate that "sam" is unique to the record set, and that "smith" is unique to the record set. My problem is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of

...cord and the session has the group_id''s of the groups the user belongs to in an array. Question 1: If I add acts_as_ferret :fields => [:group_id, :document_text] can I do an activerecord search like... Document.find(:all, :conditions => [''group_id in (?)'', session[:group_ids]) ? Question 2: These documents are dynamic, so they are deleted, updated, edited etc. How do I handle indexing in these circumstances? Delete all and recreate -or- is there a way to just delete an index by document_id and recreate it just for that document. I am going to try this in the app but...

1. I'm attempting to test for Random Effects. I've grouped the data on subject (grid) but want to use lme to build the model without subject as a RE then add it and do anova between the 2 models. This is the result I get and it appears it's adding Random Effects. tmp.dat4 <- groupedData(Trials ~ 1 | grid, data = tmp.dat4) mod2a <- lme(Trials ~ factor(group_id) + reversal,

Hi I have 3 tables as 1) user_groups id | contact_id | group_id | group_user_type_id 2) contact id | name_first | name_last | 3)contact_email_addresses contact_id | contact_email_address_type_id | emailaddress Now I have group_id sa for example 68 What I want is from contact_email_addresses table get all the emailaddress with contact_email_address_type_id=2 for the contacts

In the example in the documentation, I see: rs <- dbSendQuery(con, "select Agent, ip_addr, DATA from pseudo_data order by Agent") out <- dbApply(rs, INDEX = "Agent", FUN = function(x, grp) quantile(x$DATA, names=FALSE)) Maybe I am a bit thick, but it took me a while, and a kind hint from Phil, to figure much of this out. It is clear that the SQL

I want a page that lets users add members to a group from a longer list, or remove members from that group. I can use Ajax to transfer a name from the long list to the group, or drop an existing name from the group. But. If I add a person to the group, and try to remove without refresh, it doesn''t work. My link is formed by <%= link_to_remote ''add'', :url => {
