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.

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''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

All, I''m starting to see view state information creeping into my model class. For example, I have text fields in my view that need to be set a certain way depending on whether or not a checkbox is checked. And while the values of these text fields ultimately do represent database columns that are related to the backing AR object, the text_field values also represent attributes on a

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

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, 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

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

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

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

All, My apologies if this is a little long-winded and stream of consciousness-y :). SUMMARY: Why do we extend ActiveRecord instead of mixing it in to our model classes? Been thinking about my app''s models and starting to want to build something of a hierarchy. I have some commonality across 3 of my model classes and I''d liek to aggregate the behavior in a superclass.

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'' :

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, 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

I see that if I use the date_select helper in my view, then in the generated page, my selects are named obj[datetime_field(1i)] (and 2i and 3i for the other parts). These auto-populate the date portion of my datetime_field. I have another datetime field that I''m presenting the time from and I would like to use a similar scheme to autopopulate it. Currently, I''ve used the

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

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

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
