similar to: Really enjoying RoR after about 80 hours with it

All, In JSP, I can output strings in the Web page by either <%= foo %> //foo is a string or returns a string or <% out.write("test") %> //write directly to the output stream. What is the method of "writing to the output stream" in RoR? Basically, what is the equivalent of out.write()? I have an if then statement that I want to put around a call to h

So having just learned how to do has_many :through as opposed to HABTM, and then, being concerned that I wouldn''t get it to work, I started thinking about these two approaches. It seems to me that the _only_ problem that the HM:T (has_many :through) approach solves that HABTM doesn''t is the issue of the potential collision of id columns between your join table and one of

All, In a template, I have <%= text_field :target_list, :DateReceived, { :title => ''uploaded_at'', :class => ''target_list_info'', :disabled => ''true'' } %> Here is the DateReceived method on my

I am trying to put some smarts around a call to <%= error_messages_for %> so that when I first come into this page i.e. when my instance variable @target_list has not been defined yet, the page doesn''t break. I''m doing this: <% if @target_list? %> <%= error_messages_for ''target_list'' %> <% end %> I get a syntax error on line 1.

All, I''ve decided to jump into Migrations before I get too far along on the DB side of things. I already have some tables built, and I went ahead and built the migration that would have created them from scratch, and I made sure that there was a self.down section to drop them. I wanted to verify that I could roll back so I figured I would use rake to drop these pre-existing tables

I am doing an Ajax call in my page to a controller method like so: new Ajax.Request(''<%= url_for(:action => "target_list_add" )%>'', { asynchronous:true });" In my controller method "target_list_add", I do something and then I say: redirect_to( :action => ''target_list_upload'', :layout => false ) I know for certain

We had an after(:each) callback that looked like this: PurchaseOrder.find(:all).each {|po| DraftInvoice.find_all_by_po_number(po.po_number).each {|di| di.destroy}} which we were hoping would reset some purchase order data in a certain way. However, because we have "self.use_transactional_fixtures = true" set in test_helper.rb, this code was never getting committed. So, I just

I don''t want to put certain code in my controller because I think it makes things more confusing. What is the best way to manage business logic such that it doesn''t end up in the controller? Basically, where should I put my regular utility classes and backing objects that may not be models? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

All, I have an ActiveRecord object that I need to be able to uniquely identify _before_ I actually save the object (I may not end up saving the object based on conditions). This is because I want to use the ID in another context (a file name in the filesystem). Depending on conditions, I may or may not need to do a lot of stuff between the time that I generate the object ID and actually

All, This isn''t strictly a problem or issue with RoR but I wondered if someone might have some insight. I have a DIV on a page which I am using to "preview" the contents of a URL provided by the user. Basically, when the user clicks on a link, I do an AJAX call to an action which uses Net::HTTP to request the URL in question and then update the DIVs innerHTML attribute

Here is my class: class Document < ActiveRecord::Base public def initialize puts "Called initialize..." super.initialize end This generates the following error: You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.initialize WTF? Wes -- Posted via

All, I''m building model objects for existing tables that I cannot modify. In AWDWR, Dave says "Note that our join table has no id column...The second reason for not including an id column in the join table is that AR automatically includes all columns from the join tables when accessing rows using it. If the join table included a column called id, its id would overwrite the id

All, I''ve downloaded and installed a plugin into my vendor directory. How do I then take advantage of it? It has an init.rb file which has the appropriate require. What do I need to do to make sure that the plugin code gets loaded? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

I have an application where I am allowing users to upload (or refer the app. to) arbritrary HTML that I am (currently) displaying in an IFRAME on a page. The users will be authenticated so it''s not open to the entire universe. I was always uneasy with this, but after reading the security chapter of AWDWR, I am even more concerned. What kinds of applications do people have out there

Simple question: How does one do URL encoding in Ruby/Rails? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

I had a situation where I wanted to use a <%= %> (scriptlet) in my text_field call to set the "disabled" attribute on the text field, like so: <%= text_field(:current_job, ''removeLinkPos'', :value => '''', :id => ''offset'', :maxlength => 2, :disabled => <%= sometest ? ''true'' :

All, I have a left navigation partial that I want to dynamically generate CSS classes for based on the current controller action. In my ERb template, I have <DIV class="<%= get_menu_display_style(''login_form'') %>"> In application.rb, I have the method get_menu_display_style defined as: public def get_menu_display_style(action_requested)

All, I want to run automated unit tests as part of my build. I am building to my test environment. Upon successful completion of all of my unit tests, I would then like to load some data (using a fixture, I imagine) into my test database that will act as fresh "system test" data for my users to play with. What is the best way to "load the standard system test/user acceptance

Has anyone attempted to run Rails inside of JRuby? Is that even possible? Aside from the performance implications, is it a bad idea? I''m thinking that it might be useful in very rare cases where a Ruby/Rails - equivalent of a Java solution may not exist yet. Any thoughts? Wes -- Posted via http://www.ruby-forum.com/.

I''m trying to make my validation conditional using the :if construct. If I want to just test for the existence of the field EMAIL, it seems like I could just do: :if => ''! EMAIL.nil?'' or do I have to use a proc? And if I use a proc - what gets passed into the block - I assume the currently validating field - is that right? Thanks, Wes -- Posted via
