Hello People, I have a possibly very lame question. I am fairly new to RoR, and I want to make sure I do it "right". I have a model called Invoice, and one called InvoiceLines. Usual story: the table "invoice" has a 1:n relationship with "invoice_lines", which includes invoice_id. Now... the application will have a "new order" button, which will allow

ruby 1.8.6 (2007-09-24 patchlevel 111) str = ''\&123'' puts "abc".gsub("b", str) puts "abc".gsub("b", "#{str}") puts "abc".gsub("b", str.to_s) puts "abc".gsub("b", ''\&123'') puts "abc".gsub("b", "\&123") >ruby test.rb ab123c

Dears, Remembering last value in a select box don''t work for me as : Controller : @years=(1970..2005).to_a Form: <%= select_tag "year", options_for_select( (2001..2005).to_a, @params[:year] ) %> I had to write <%= select_tag "year", options_for_select( (2001..2005).to_a, @params[:year].to_i ) %> for it works. Not important, but I''m

Hi, I often find myself using bits of code like this inside ActiveRecord, perhaps it''s useful for others, or others can improve on it: ########### # fix user input before validating it before_validation :sanitize_input # santize input before actual validation is called # this uses the little methods defined below def sanitize_input trim %w(adres postcode woonplaats email naam

Hey all, I''m storing an array of timestamps in a field in my database as an array. When the items get saved, however, some minus signs are appended to the text: sample output: --- - 1151971200 - 1152576000 - 1153180800 - 1153785600 - 1154390400 Is this normal behavior? When I retrive the value out of the database and .to_a, the three minus signs (---) are counted as the first

Hi ! I just have a simple question. I am writing an app using rails to familiarize myself with the framework (which is pretty cool, by the way). I just wanted to know why these two work differently (since "find" should be a synonym for "detect" according to the Pick Axe) : current_item = @invoice.line_items.detect {|i| i.product.id == key} current_item =

Hi fantastic rails core developers. Speaking of version 2.3.5: I find it rather error_prone that values such that "some text" is silently converted to false when stored in a boolean DB field. Among other things it means that assign "some text" to boolean fields on a model will not generate any validation messages (it will silently be converted to false). I think it is like

I have a multiple select menu: <%= select_tag ''resume[employer_1_industry][]'', options_for_select(industries_helper, @resume.employer_1_industry), :multiple=> true %> It produces this HTML: <select id="resume[employer_1_industry][]" multiple="multiple" name="resume[employer_1_industry][]"> <option value="">-

OK, thanks to Kelly I got my options_for_select in a select_tag helper method to use a Ruby range as a value. Now when the user makes a selection from that list, I can''t figure out why the result doesn''t get stored in the database. The line in the _form looks like this: <%= select_tag(:month, options_for_select((0..12).to_a)) %> Pops up an option menu.

I am trying to upgrate rails from 3.0 to 3.1, while updating rails version I am getting following error rake aborted! undefined method `sanitize_limit'' for #<ActiveRecord::Relation:0x2aaaad35d720> /some_package/lib/ruby/gems/1.8/gems/activerecord-3.1.12/lib/active_record/relation.rb:460:in `method_missing''

Hi, I''m encountering another highlighting issue. (about the first one "range search and highlighting", i received no response. I don''t even know if somebody tried to reproduce and/or if it''s normal behavior) about the new issue, an example will be easier for you to reproduce: I''m filling an index with random data, i try to match for "*1*"

After I upgraded from rails 3.2 to 4.1 I am getting this error below. I researched that Rails 4.1 requires a conversion of an activerecord_relation to an array using to_a. I did use to_a but looks like rails is doing a select count behind the scenes. Do you know how to fix this? def index order_type = params[:order_type] @oh = OrderHeader.select("orders_header.*, users.username,

Hi all, This question might be a long shot, but I''m going to ask it anyway. In my application, I''ve created a before_filter that does some magic. It looks like this: if request.xhr? then render :update do |page| page.redirect_to url_for_thingy end else redirect_to redirect_to url_for_thingy end This works perfectly, however, I have one annoyance. On the server side,

I have the following code: advertisements_arel = Advertisement.order("advertisements.id DESC").arel @advertisements = (params[:website_id].present? ? advertisements_arel.where(:website_id => params[:website_id]) : advertisements_arel).to_a It returns a struct Arel::SelectManager::Row data But I''d like it to return an array of Advertisement objects (like it would

Not sure if this is possible currently. I have a section of code like this: ActiveRecord::Base.transaction do cow.save! duck.save! dog.save! end (Names changed to protect the innocent.) I''d like to specify that the saves run in a transaction. I can do ActiveRecord::Base.should_receive(:transaction).and_yield But is there any way to specify that the code is
