search for: each_key

Does anyone know of a good example somewhere of an implemention for adding records with HABTM relations that have lots of possibilities. The best way that I''ve seen it done is where you have two lists (multiple select lists) where you have the possibilities on the left and ones you''ve added on the right with arrows to add and delete items. But the only ways I know how to

I have a controller method called update_all that grabs parameters for about 30 form fields and saves them to the database. My current code looks to see if there is a string in params[] for each form field (two fields for each SelfEvaluationItem) and saves the updated self_evaluation_answer if a string is available. Since this is iterated code, I am almost certain that this generates 30 or so

This is the code if !params[:ratings].nil? params[:ratings].each_key do |r| @selected_ratings << r @movies << Movie.where(''rating = :rating'', :rating => r) @sort = params[:sort] end elsif @selected_ratings = @all_ratings @movies = Movie.order(@sort) @sort = params[:sort] end This is the erro...

Is there a way of retrieving all the request parameters without name in the controller. Thanks & Regards, Asem -- Posted via http://www.ruby-forum.com/.

Hi man, Thank you very much for your good work. I think there may be a bug in Mechanize 0.6.3. Cookie:cookies (cookie.rb:L83 ) @jar[domain].each_key do |name| => if url.path =~ /^#{@jar[domain][name].path}/ if @jar[domain][name].expires.nil? cookies << @jar[domain][name] elsif Time.now < @jar[domain][name].expires cookies << @jar[domain][name]...

I need to include another helper module apart from the normal two (ApplicationHelper and [controllername]Helper). The inclusion needs to be dynamic and based on external parameters (ie what helper that get included differ from request to request). Is it possible? How? /Marcus

Hi all, Has anyone ever thought about or implemented a way to use Rails to pull content from a database and actually *generate* static html pages from view templates? I want to throw a bunch of content into a db using rails and then put all my website templates into the views dir and write the files out with the content inside. The funny thing is that the html pages Rails normally outputs to

Is there an easy (and secure) way to search your database when you don''t know the number of parameters ahead of time? I can see doing it by concatenating together an sql query, but hopefully rails provides a more elegant way to do this with ActiveRecord without making a ginormous switch statement? For example, lets say my search form has 4 different input boxes. I only want the query

Hi, I''m trying to do a bulk update on an array with the helper text_field. I''m trying to create an inputfield for every object in the array, but I''m not getting it right... example: class ClassA @arrayB[] end HTML (code with error): <% 0.upto(9) do |index| %> <%= text_field ''ClassA'', ''arrayB[index]'' %> non

I cannot work out why this error is appearing. ActionView::TemplateError (can''t convert ActiveRecord::Error into String) on line #3 of app/views/button/_show_enquiry.html.erb: 1: <h1>Send us a message</h1> 2: <% remote_form_for :enquiry, :url => {:action => ''send_mail''} do | f| %> 3: <%= error_messages_for ''enquiry'',

Please could someone suggest what might be wrong here. In my view I''m displaying a series of check boxes and when the form is submitted I want the controller to iterate over the values and contatenate them all into a string "1" if the box was checked and "0" if it wasn''t. I''m new to Ruby and Rails and I can''t seem to get any values out of

Hi, Can Ferret be configured to change the minimum word length of what it indexes? Right now it seems to drop words 3 characters or less, but I''d like to include words going down to 2 characters. How would I do that? Francis

Dear all, I have a custom fact, that reads a file and then generate the values dynamically based on the file content. It''s something like this: inFile = "/home/admin/OSs.txt" > gos = {} > > if File.exist?(inFile) > open(inFile, ''r'').each do |line| > next if line =~ /^\s*(#|$)/ > parts =

OK, so i''ve played a bit with mocks and mock_models in controller and view tests and i have a question. Is this statement really correct: "We highly recommend that you exploit the mock framework here rather than providing real model objects in order to keep the view specs isolated from changes to your models."
