similar to: finder_sql patch problem

Dears, [Rails 1.0.0] I''m working with a legacy schema, and around my 20+ models i''ve used some AR constructs. They are based on a finder_sql doing some dirty sql and using #{id} from the ''pivot'' model for extracting data in other tables. like : class Division < ActiveRecord::Base set_table_name "legacy_division" set_primary_key

Guys, I have a need to support as has_many/belongs_to relationship on a legacy(kind of) schema. The reason I say kind of is that the schema does have "id" columns that are used in many associations, but this particular has_many/belongs_to association needs to support different ones. I''ve attached to code at the end of this email. Suffice it to say I need to use the standard

I''m sure there''s something right under my nose that I''m missing. I have two tables with two parallel one-to-many relationships. I wish to use the :finder_sql parameter to essentially ''or'' the two foreign keys. What isn''t working for me is performing a ''sub-search''. Let''s say the tables are "stores" and

hi all, I have a Class, Client, which has_many projects (Project class). the projects depend on a session_id variable, however. So the question is, how can I do the following: has_many :projects, :finder_sql => "SELECT p.* FROM projects p INNER JOIN projects_users pu ON pu.project_id = p.id WHERE pu.user_id = #{session[:user_id]}" The problem is that I need to filter a

Hello, In a model I have: has_many :things, :finder_sql => '' select * from other_things '' + '' where id = #{id} '' When I do MyClass.find(:all, :include => :things) I get a weird error: from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract_adapter.rb:120:in

I''m building an app that needs i18n support across the entire database (i.e. localized attributes). In order to do this I''ve created a special HABTM join table that can be associated with _any_ other table: create table language_strings ( for_table varchar(255) not null, foreign_id int not null, language_id varchar(5) not null, attr_name varchar(255) not null, value text

I have an inner join query that Action Record can''t seem to pull off conventionally, so I''m trying to use :finder_sql to utilize an sql query that works beautifully in SQL. The problem is, when I try to call the method, I get the following: private method `gsub'' called for #<Array:0x267de04> Here is my has_many code: has_many :mod_privileges,

This is my first rails app with a legacy database and I''m having a terrible time getting the models set up correctly. I have an order table that has a primary field named order_number. I have a name table with a primary of item_number. These two tables are liked by the item_number and the order_number, but not as you might think. If the order_number is 2500, then each entry in

I can submit a patch, but wanted to confirm I''m looking at this right... The docs indicate that if you specify a has_many association with :finder_sql, but no :counter_sql, it constructs the appropriate counter sql by substituting the SELECT clause. But has_many_association.rb doesn''t seem to do that -- it just passes Base#count_by_sql the finder_sql, which doesn''t

Hi all, My question is somewhat complicated, but bear with me. My project has a number of models: User, Program, and Team. Users belong to multiple Programs. Programs have multiple teams, but Teams belong to one program. For each Program a User belongs to, he can belong to multiple Teams. (Think of this in an athletic context where users are athletes, programs are universities). So my

Hi All, It seems that :finder_sql in a HABTM association only interprets a single quoted #{id} the first time through a query. I see examples of this being used in a few places (though with has_many) and I don''t really see how to use :finder_sql without a #{id}. Am I missing something or is this just broken? -- Paul Haddad (paul.haddad@gmail.com paul@pth.com)

from the api I got: <pre> has_many :subscribers, :class_name => "Person", :finder_sql => ''SELECT DISTINCT people.* '' + ''FROM people p, post_subscriptions ps '' + ''WHERE ps.post_id = #{id} AND ps.person_id = p.id '' + ''ORDER BY p.first_name'' </pre> I would like to pass in the

I''ve got an order model that stores order data. One piece of data is a credit card type, which is a digit 1,2 or 3. I have a cardType model that has an id, shortName and LongName for the credit card merchant (visa, mastercard, amex). I want to be able to say: order.cardType.shortName, but can''t seem to get has_one working. It works with has_many and a finder_sql statement on

I never would have figured this out in many moons: has_many :subscribers, :class_name => "Person", :finder_sql => ''SELECT DISTINCT people.* '' + ''FROM people p, post_subscriptions ps '' + ''WHERE ps.post_id = #{id} AND ps.person_id = p.id '' + ''ORDER BY p.first_name'' Variable

Is it supposed to do that? I find it very confusing. AR 3.0.10 class Unit has_many :units, :finder_sql => proc { "SELECT * FROM `#{table_name}` WHERE `location_id`=#{id} AND `location_type`=#{Location::UNIT}" } end Both should return []. However... >> Unit.first.units.find([1000000]) [2011-09-27 10:05:11|main|debug] Unit Load (4.0ms) SELECT `units`.* FROM `units`

I have this code in a view: <% for topic in @topics %> <%= topic.id %> <%= topic.dr_title %><br/> <ul> <% for doc in topic.child_documents %> <%= doc.dr_title %><br/> <% doc = nil %> <% end %> </ul> <% end %> Though the topic titles and IDs display correctly,

I''m getting this error in webrick then it crashes leaving nothing in the log. ruby: symbol lookup error: /usr/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.so: undefined symbol: mysql_sqlstate Here is the standard query I would normally write to get the data. select * from child,parent where CONCAT(SUBSTRING(child.item_number,1,14,''00'') = parent.order_number and

Assuming you have Person that has_many :messages, what will it happen if it has 10000 messages? Will rails attempt to initialize @person.messages with 10000 rows from database? If that is the case, is combining finder_sql and counter_sql the common practice to avoid this? Bogdan _______________________________________________ Rails mailing list
