similar to: join fields for list views

I have a number of models that use an aggregation to combine First Name, Middle Initial and Last Name and they have been working fine. I am looking to clean this up, DRY it if possible. I have things like this in application.rb class Clwholename attr_reader :first_name, :middle_initial, :last_name def initialize(first_name, middle_initial, last_name) @first_name = first_name

I simply can''t figure this out. I have been reading and re-reading Agile book and wiki.rubyonrails.org - all sorts of validation methods and still, it doesn''t work. Controller code def create @client = Client.new(params[:client]) if @client.save! flash[:notice] = ''Client was successfully created.'' redirect_to :action =>

Trying to use Eric''s help and Amy Hoy''s page of playing with auto_complete and decided that the script/console is the place to rapidly test. I have this feeling that CONCAT isn''t working for postgresql... c = find_by_sql(SELECT * FROM clients WHERE CONCAT (first_name,middle_initial,last_name) = "johnadams") ^ (irb):61:

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

I have the text_field_with_auto_complete woking on my user DB using last_name. so looking for ''ivanoff'' works great, but I can''t find ''john''. Plus I like to have ''last_name, first_name'' show up in the dropdown. what I can''t figure out is how to concat first_name and last_name to make a name and use that to look it. working

I am trying to get more out of auto_complete than it apparently was designed to deliver. My problems seem to be two fold. 1 - I use aggregations on names... :first_name, :middle_initial, :last_name and then aggregate them using a composed_of :wholename thing auto_complete_for seems to be wired to only use table columns directly and gags on the aggregate form. 2 - foreign table columns -

Trying to use Amy Hoy''s ajaxariffic auto_complete methodology and I am getting really close to the end. This is fairly complicated but I will simplify as best I can. My view code is simple... <%= text_field_with_auto_complete ''client'', ''wholename'' %> # wholename is not a column in ''clients'' but rather represents an

I can''t see how to use variables so I am using console to test things out... clients table - a column named first_name My very brief console session... >> clients = Client.find_by_sql("select * from clients where first_name = FN") ActiveRecord::StatementInvalid: RuntimeError: ERROR C42703 Mcolumn "fn" does not exist Fparse_expr.c L1034

All of the tutorials and the Agile book use MySQL and I''ve got that working. I am now trying to use PostgreSQL and can''t seem to get going. Is my problem the db setup in postgresql? I have installed postgres-pr The error message when I try to access http://localhost:3000/clients when using PostgreSQL (MySQL works fine) ActiveRecord::StatementInvalid (RuntimeError: ERROR

Hi folks, I''m curious how a lookup with a large group of values would be handled in Rails. For example, I have a (contrived) AnimalType filtering a list of many Animals--more than can be presented comfortably in a dropdown box. Therefore I need to either redirect to another screen to select an animal (returning after the selection is made), or show a dialog--modal or otherwise--to

Hi, I render a couple of date_select fields, the HTML looks fine, I can see the values submitted back to the server, but AR doesn''t pick them up from the hash in Booking.new(params[''booking'']). I''ve got a ''booking'' object with parameters product, startdate and enddate. HTML snippets: <select

I was reading through the FlexMock docs and noticed the expectation method .mock, which returns the original mock associated with an expectation. It looks really handy for writing nice all-in-one mocks like: mock_user = mock(''User'').expects(:first_name).returns(''Jonah'').mock So I started playing around with mocha and found I could actually already do this!

I have a form with about 30+ fields, which the client is wanting to separate into 3 pages/steps - just wondering what is the best way to go about this, specifically remembering data entered, from one page to another, and making sure the various bits of data are validated correclty, error messages outputted etc etc... is there a best practice method for doing this? -- Posted via

because I am a grasshopper... Now that I can sort my ''list''...is there a logical way of not repeating myself to having essentially the same list view with multiple sorts? i.e. def list_cl # ordered by clients last name @placement_pages, @placements = paginate( :placements, :include => [:client], :order_by =>

I''m using Rails Recipes to create a login form but instead of username and password, my setup is firstname, lastname, password. I seemed to be gramatically challenged and not sure how to set up the parameter list. Can anyone offer up a suggestion. The book shows the method starting like: if request.post? user = User.find(:first, :conditions => [''username = ?'' ,

Hi! I faced some issue while using it for dynamic attrs indexing/search. Maybe I made something wrong. Here is test method. Everything works just fine until last line http://pastie.caboo.se/66274 . Tested on both stable and trunk of aaf and ferret 0.11.4. the short version of code below: Contact.acts_as_ferret :fields => [ :first_name ] assert

I''m getting this error message since i moved alot of the database logic to the model. wrong number of bind variables (0 for 2) in: first_name = ? AND last_name = ? def self.authenticate(first_name, last_name, password) user = User.find(:first, :conditions => [''first_name = ? AND last_name = ?'']) if user.blank? Digest::SHA256.hexdigest(password +

wrong number of bind variables (0 for 2) in: first_name = ? AND last_name = ? I''m not sure why I"m getting this error ? def self.authenticate(first_name, last_name, password) user = User.find(:first, :conditions => [''first_name = ? AND last_name = ?'']) if user.blank? Digest::SHA256.hexdigest(password + user.password_salt) != user.password_hash

I''m trying to use composed_of within my model. I have a field in my database named ''card1'', which is simply a string. I have this in my model class Player < ActiveRecord::Base composed_of :card1, :class_name => ''Card'' end class Card attr_reader :value, :suit def initialize(s) @value = s[0].chr @suit = s[1].chr end end The

The users will enter students names on forms. How do I intercept the first and last names and have them stored capitalized when the user inputs them in lower case? Do I mess with the form html, skipping form_for helpers and using conditional clauses in the view? Do I need to separate out the individual attribute and update it separately in the controller actions that save/updates the
