Hi, I would like to be able to dynamically (without reloading the page) change the values from one listbox when a user select items from another listbox. I have a model ''Sector'' which has_many ''levels'' (and of cours, ''Level'' beyong_to ''sector''). I want to show the user two listboxes with the sectors and levels. But

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

All, I''m populating a view with checkboxes in a list. I want to be able to assign to my has_many relationship using the post values of these checkboxes. Essentially, I want to populate the relationship table which will create the correct join values in my model. Here is my check_box_tag code: <%= check_box_tag("@current_job[target_list_ids][]",

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, Thanks for any help in advance. I have what I think is a very straightforward partial template and I can''t figure out why a text_field call within it doesn''t work. Here is my calling template: lists.rhtml <div id="target_lists"> <%= render(:partial => "target_lists", :collection => @target_lists) %> </div> In the partial

All, I would like to test some secure pages that I''m developing in my WEBrick-based development environment. I''ve done some research and it appears that I need to create a new command that will start a HTTPS based WEBrick server. Is this correct? Also, it appears that the https.rb module is not included with the WEBrick bundled in Rails. So, I will need to go get that

Rails 1.2.3 It appears that the select_year helper doesn''t accept HTML attributes as part of the options array. Does anyone have a way to successfully pass an :onchange attribute in to the select_year helper? I''m going to do it with Javascript directly for now.

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

All, I''ve run into a snag. I need to handle the display of elements on my page and I want to use my Javascript event handlers on page load. However, my BODY tag is trapped in my generic layout. I''m thinking that I can put an onLoad on the BODY tag that will just call a Javascript method called initializePage() and then provide this initializePage() call in my specific page

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)

Anyone know of any Ruby modules which can be used to parse an HTML page ? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

All, I''m wanting to initialize an ActiveRecord object. I understand that there is a method called after_initialize that appears to get called right after the ActiveRecord object is instantiated. Is after_initialize a Ruby thing or a Rails thing? Where is after_initialize documented? Can I pass parameters to it? If so, how? I want to initialize the "belongs_to" attribute 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

All, If I do ruby script/generate model blah, is there an easy way for me to remove all of that stuff that got generated? Something like: ruby script/remove model blah? If it doesn''t exist, is it coming? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

Can you set a global before_filter action in application.rb? So, for example, you could control authentication for all of the controllers in an app.? Obviously, you would need a way to reference actions by controller within this "global before-filter". Thanks, Wes -- Posted via http://www.ruby-forum.com/.

All, I''m finally doing my first real form in Rails - the model object that I''m entering information for has 8 validations so far. If I type in good values for all the fields but one, I get the pretty validation, and the nice field highlighting, but all of the fields are cleared, forcing me to retype all of that info. That is a big drag. Is there a standard way to get the

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.

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 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

The ActionMailer/ActionPack gem release is still screwed up. Does someone test the gem releases to ensure that they work? Just an idea. Wes -- Posted via http://www.ruby-forum.com/.
