similar to: What does the send() method do on a model object?

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 have two ActiveRecord objects. TargetList has_many Targets Targets belongs_to TargetList I''ve specified belongs_to :target_list, :foreign_key => ''DataSetID'' Queries generated by various methods in target_list do not seem to see the foreign_key name and keep trying to query my Target table using "target_list_id" (the default foreign

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''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][]",

I just took my HABTM and turned it into a :through since my join table has another "non-joiny" attribute. I went from this: has_many_and_belongs_to :jobs, :join_table => ''tablename'', :foreign_key => ''x'', :association_foreign_key => ''y'' to this: has_many :jobs, :through =>

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, 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 have a global layout in application.rhtml and I''d like to render a partial template within it. Currently, I have this: <%= render (:partial => ''side_nav'') %> but it seems to be looking in the controller specific view directory. What is the best way to do handle controller - global partial rendering? Wes -- Posted via http://www.ruby-forum.com/.

I have a database with a couple of tables. One table called spares has foreign keys in another called equipment. When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

Announcing... JobsOnRails! I''m creating on a Ruby on Rails oriented job site and will be launching in the next few weeks. It''s a Rails-centric place for developers and employers to get in touch with a minimum of hassle. For now, I have a short outline of my ideas and an email signup form on the live site at http://www.jobsonrails.com. The site is coming along nicely and

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

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/.

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

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/.
