I have the following models: class Resume belongs_to :resume_assignments end class User belongs_to :resume_assignments end class ResumeAssignment has_one :resume has_one :user end When I delete a resume, I want to make sure that its associated ResumeAssignment gets deleted also.

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

Hi I''m new to Rails and I''m struggling with a ''has-one'' relationship. I''m trying to save product and image data in seperate tables with one to one relationship.

Hi, I''m trying some RJS to update a series of list boxes in which the user selects a state, and the following list gets updated with a list of counties, and the same for the next list of areas. My code works perfectly (albeit a bit slow) on Firefox, but on Internet Explorer it clears the list box (instead of filling it) and Netscape shows all the counties cramped together on one

Hi all, I am using "validates_presence_of" for validating all fields of my registration form. It is working fine and generating custom error message as mentioned. Also clearing all fields.

I''m new to Rails (and liking it!) and I have multiple controllers, each of which has a method which uses a view template which is identical to what the others use. I would like to be able to have just one template to maintain that they can all use. What is the customary way to do this? I tried using render_action to specify the template explicitly, and it "works". But I

I have the following view template: <%= form_remote_tag :update => "new_item", :url => {:action => ''create''}, :before => %(Element.show(''spinner'')), :success => %(Element.hide(''spinner'')) %> <div id="new_item"> </div>

Hi Is there a render_action matcher to go with render_template? I can''t see any mention of one in the docs. Do you have to still do it old- school? Thanks Ashley

Hi, Just wondering how I get both the current date and time to display here (so far I can only get the date OR the time): @tblregisteredphone.txtregisterdatetime = Date.today Also, how can I change the format of the date and time from: Tue Apr 04 00:00:00 GMT Daylight Time 2006 to 2006-04-04 12:04:00 ??

Hi all, After working on my first rails app and having handed over some very sophisticated coding from a lot of you guys. My app does what I want it to do, but I''m no where near the end yet, and it seems that the KISS and DRY objectives already went down the drain. It could be lack of knowledge, only doing Ruby on (and) Rails for a month, but I''m stuck on the following:

Struggling a little with getting the syntax right for a STI model. Prob just being a bit dense. Couple of questions I''m hoping you guys can answer: Assume here I''ve got: class Person class Manager < Person class Slave < Person 1) How does person[:type] differ from person.type when type is the column used to specify the subclass. They seem to output the same
