similar to: Eager loading with self associations

I''ve gotten eager associations to work before, but for some reason this isn''t working out for me this time. I''ve been scratching my head but can''t quite figure out the nuances of what works and what doesn''t work. I''ve got 3 models: profile, widget_configuration and widgets profile.rb -- has_many :widget_configurations

Hi - I am trying to use eager associations to cut down on database queries. I have a feeds table, an items table, a categories table, and a categories_items table. feeds have items, and items have many categories (and categories can be assigned to many items), thus the categories_items table which is a many-many join table. I do @feed = Feed.find(1) which works fine, but now I want to use

Hi all, I want to see if I''m not missing something with associations and eager loading. (I''m currently using Locomotive on OS X and SQLite3.) I have two simple tables/models, set up properly: teams has_many :matches and matches belongs_to :teams. Matches has a match number and a team_id field (along with several other fields) and teams has a team_number field (again, along with

Hey everyone, I''m currently making an application that allows users to create custom fields that have attributes associated with each field. They can then attach instances of these fields (each with their own separate attribute instances) to their account. So, it looks like this: Fields / \ Field Instances Field Attributes \ / Field

Hello all, I still have a patch for #3438 (eager loading doesn''t respect association orders); it passes all unit tests, and has additional unit tests with full coverage. The patch is attached. == The Bug == Author.find(1).posts != Author.find(1, :include => [:posts]).posts if Author has_many :posts, :order => anything. This means that either one must avoid eager loading or

There is a dedicated section about eager loading in the docs. A coworker discovered eager loading does not work in polymorphic associations the hard way :-) so I''ve written a patch that documents it: http://dev.rubyonrails.org/ticket/10610 There are at least a couple of tickets that implement something that would change that though: http://dev.rubyonrails.org/ticket/9640

Hi, I'm using full_audit vfs module and I'm seeing a lot of duplicated messages in log file. Why does it happens ? How can I configure de smb.conf not to log duplicated information ?

Polymorphic associations work great until I try to do some eager loading through :include. In my example, the interface name is ":imagehaver". Here''s my little eagerly loading find line: Image.find(params[:id], :include => :imagehaver) All it gives me is an ActiveRecord::EagerLoadPolymorphicError with no further explanation. I haven''t been able to dig up anything

I have tried to use eager association with pagination, but the :include option is not supported: Here''s the one-line pagination call without :include @link_pages, @links = paginate :link, :per_page => 10, :order_by => sort_clause and here the work around, using the "classic" method # @link_pages = Paginator.new self, Link.count, 10,

Hi friends, i''m usgin the edge version because i need eager loading on polymorphic associations support, but i see this: Message.find(:first, :include => :owner) #This generate this query: SQL (0.000072) SET SQL_AUTO_IS_NULL=0 Message Load (0.000389) SELECT * FROM `messages` User Load (0.001070) SELECT * FROM `users` WHERE (users.id IN (1,2)) And this Message.find(:first,

Hi, I''m having what I believe to be a typecast problem with ActiveRecord and Associations. In the code below, I need to flag a contact record for deletion if the contact doesn''t have any addresses or books records: sql = "select id, delete_flag from contacts where id = #{params[:id]}" contact = Contact.find_by_sql(sql) if (contact[0].addresses.count +

Hi, I''m searching for a method of eager loading polymorphic associations under activerecord 2.0.2. After some initial google-fu I came up with a link to an enhancement that''s been added to edge: http://dev.rubyonrails.org/ticket/8119 Anyone have any idea how long that might take to work its way into a general release? I''m early in development now so I can afford to

I''m looking for someone to confirm the following as a bug in Rails 1.0 before I post it to Trac. If I use eager loading on an association that has conditions defined, the conditions are ignored. The following example illustrates the problem. I have two tables: create_table "blogs", :force => true do |t| t.column "name", :string end create_table

Is there some sort of good pattern for dealing with computed values with Rails/ActiveRecord? A simple example: 3 tables, classes, students, and student_class_records (habtm style relation but contains a good deal of additional state so is modeled explicitly) Something like select the 10 classes with the most students. Easy enough in SQL. So I''m using a lot of find_by_sql and

Hi, currently the eager association loading via ":include" does not work when a has-many or habtm association is combined with offset/limit (which is required for paginations). This is because in these cases, the result set will contain more than one row per object, but limit/offset works on row numbers. I''ve developed a patch that makes this work by using 2 SQL statements

I think Rails 2.1 introduced a bug when eager loading of associations with Oracle. In 2.1 ActiveRecord loads the included table with a big ''IN'' query: ''where association.id in (1, 2, 3, 4...)''. The problem is that Oracle has a hard limit of 1000 values in an IN clause. I get this error: ''OCIError: ORA-01795: maximum number of expressions in a list

If I ''find'' using :include, and some included associations are null, then looping through the array executing ''if obj[i].assoc'' accesses the database for a second time (as obj.assoc is nil). eg Topic, has_many posts Post has_one email and posts = Post.find(:all, :condition => ''posts.topic_id = 10'', :include =>

Hi Railers, Is there a way to specify all relations in a :include option while find()ing? I have a model with a lot of associations, and sometimes i would like to query for all them. Something like Model.find(params[:id], :include => :all) would be nice. Alternatively, i don''t know if there is a mehod to retrieve all model''s associations, to do something like
