similar to: find_all_by deprecated?

In the Agile RoR book, page 219 (softcover version) they talk about the fact you can use the methods: find_by_ and find_all_by_ and fill in the last piece with a valid column name. So I have a database table called "parts" and the following columns: id partname partnumber vendor I do the following: (connection to DB already established) class Part < ActiveRecord::Base end

I started with Ruby on Rails in the 0.13.x period, so I''m sure I missed out on a lot of history. There''s probably some good explanation for something I''ve been wondering about, but I haven''t seen it written down anywhere. Maybe someone can clue me in. I''ve always felt that one of the uglier APIs was the ActiveRecord::find() method. I call

So....let''s have a look if I understood the issue: -Find_all_by is actually the same like Find(:all), however Find_all_by is much shorter and less complicated than the syntax of Find(:all) -So in my CONTROLLER it says @files = find(:all) however I don''t want to see all files displayed in my selection box, because I only want to see the foles whose mandant_id is the same like

When I use find_by_name method I get LIMIT 1 result. > SELECT "users".* FROM "users" WHERE "users"."age" = 25 LIMIT 1 But the "age" column is not unique in my table and its value may repeat. So I expect that an array of records where "age" is 25 will be returned. But AR limits the query by 1. How to avoid it? Or is it the default

I was hoping that AR''s find_by_* magic methods would help me retrieve multiple items somewhat like the following: names_to_find = [''Larry'', ''Moe'', ''Curly''] found_people = Person.find_by_name(names_to_find) Is there a way to accomplish this using find_by_* (or even find(:all) using some sort of conditions) or must I resort to SQL

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database. For example, I have the following models: class Parent < ActiveRecord::Base has_many :children, :conditions => "deleted_at IS NULL" end class Child < ActiveRecord::Base belongs_to :parent, :counter_cache => true end With the following

Hi there, I''ve just installed login_engine and user_engine from the repositories, followed the setup procedures as documented in: vendor/plugins/user_engine/README But I''m getting the following failure: vince@vaio:~/Projects/Booking$ rake bootstrap (in /home/vince/Projects/Booking) rake aborted! undefined method `edit'' for class `UserController''

Hello all, I just ran into something that I think is a bug, and I would like to confirm with the core team whether this is expected/desired behavior or if this is a bug that I should file and develop failing tests for (I doubt I have the active record method_missing fu to actually patch it). Test Scenario: I would like to find or initialize a new user and base the find on the users email

I am doing a typical database list, but when I do <% for m in @private_messages %> (Line 28) It tells me that the method ''each'' is undefined. What''s wrong, I did not call the method each.... Here''s the error: Showing app/views/account/mail.rhtml where line #28 raised: undefined method `each? for #<PrivateMessage:0x408bb830> Extracted source

I''m trying to ''destroy'' a particular record of a table >From the controller side, i''ve found a list of possible records that i want deleted. ie. @chart = Chart.find(:all, :conditions => ["record_id = ?", param[''id''] ] ''id'' is passed into the controller and @chart is all the possible records that have

OK, I have some basic functionality to support bind variables, it appears to work with the ''old'' %s style too. I''ve altered sanitize_conditions in activerecord/lib/active_record/base.rb to check whether bind variables are in the statement (/\?/). If they are, replace all the ?s to escaped values from the arguments array. else santize and expand. There are a few

I am getting random can''t connect to MySQL server errors on my Rails application located at http://www.thedatingguy.com/blog Do you have any clue why this is happening? This is the error: Mysql::Error (Can''t connect to local MySQL server through socket ''/tmp/mysql.sock'' (61)):

I think I must be missing something obvious... I have... class OrderController < ApplicationController model :order scaffold :order def list @orders = Order.find_all_by_status(@params[:status], :order => "date" ) end end class Order < ActiveRecord::Base belongs_to :customer end and i''m getting... /Unknown column ''orderdate'' in

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

In my app, a user logs in [via the login generator] and has access to details of his account, and transactions attached to his account. This is achieved in the standard rail manner by passing the account id or transaction id between the controller and the view. But what is to stop someone hacking the URL or view html to access another account id or transaction id ? eg /account/show/46 becomes

Hi, I have been playing around with Ruby after reading so much about it, and so I started tweaking with auto generated scaffold. But it seems like I must be missing something, can someone else please help me take a look and give me a couple pointers? In short I was trying to make a class User that has a method addupdate with 2 parameters (alias and email) which would either update the

class AppointmentBook < ActiveRecord::Base has_many :appointments def lookup(date, look_ahead = 27) return nil unless block_given? (date..date + look_ahead).each do |date| yield(date, appointments.find_all_by_date(date)) end end end The line with yield is throwing the error: undefined method ''each'' for #<Date: 4908761/2,0,2299161> A YAML

I have added roles and roles_users table and updated the model so that my users can have multiple roles. ("Admin" role does always have id = 1). I have added these methods to my application controller. <code> helper_method :is_admin? helper_method :is_user? def is_admin? if @session[''user''] @session[''user''].roles.find(1)

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''
