The following is a kludge to generate a drop down list of the rows for
the "categories" table (from the "Category" model).
thufir@arrakis ~/Desktop/strawr $
thufir@arrakis ~/Desktop/strawr $ tail app/views/feeds/show.rhtml -n 2
<%= select(:category, :id, Category.find(:all).collect {|c| [ c.category,
c.id ] } ) %>
thufir@arrakis ~/Desktop/strawr $
However, I''d rather put a method in feeds_controller.rb if
that''s
possible. Would that be a better way to generate the drop down list?
thanks,
Thufir

If you want the helper to be available to all templates in the app, define it in application_helper.rb otherwise define it in category_helper.rb.

It''s like putting onion in ice > cream.I''m not clear on what you mean. The attributes/fields for the model are defined at http://strawr.googlecode.com/svn/trunk/db/migrate/002_feeds.rb, not really in http://strawr.googlecode.com/svn/trunk/app/models/feed.rb. However, I suppose that''s still within the "model" for MVC. The point is to have the drop-down list at http://strawr.googlecode.com/svn/trunk/app/views/feeds/show.rhtml give the same result as>> Category.find :all=> [#<Category:0xb700b90c @attributes={"category"=>"some category", "id"=>"1"}>] does from script/console, albeit without the hexadecimal. I understand the generalities, that in MVC the different parts are intentionally not overlapping. Yes, the view should stay with view stuff. Concretely, what do you mean? -Thufir --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You''re doing a Model.find request in the model. This should be done in the controller.

Pardon, no I haven''t done much research into how to do that specific operation, but could I have some direction as to how to do that?

Those modules are included in view templates as appropriate. So if you have module FeedsHelper def my_helper end end You can do <%= my_helper %> in your view. From a helper you can call all the helper functions you normally have access to.

Ok, I got it working, but it feels equally kludgy: thufir@arrakis ~/Desktop/strawr $ thufir@arrakis ~/Desktop/strawr $ cat app/helpers/application_helper.rb # Methods added to this helper will be available to all templates in the application. module ApplicationHelper def select_category # select :category, :id, Category.some_find_method.collect {|c| [ c.category, c.id ]} select :category, :id, Category.find(:all).collect {|c| [ c.category, c.id ]} end end thufir@arrakis ~/Desktop/strawr $ thufir@arrakis ~/Desktop/strawr $ tail app/views/feeds/show.rhtml -- lines=1 <%= select_category %> thufir@arrakis ~/Desktop/strawr $ However, that achieves the purpose. I think what bothers me, slightly, is the complexity of the compound line in the select_category method. I can read it, sorta, but can''t write it :( However, I''ll live :) Oh, now I get it. I must be tired. I need to define a few "some_find_method"''s, like: categories linked to this feed, categories not linked to this category, etc. These methods are in the same module? I was thinking of refining the query from all records to just those records which are linked to the particular object. However, since I have trouble writing that in English, I''ll take a pass and come back to that. I would like have two buttons: "link" and "unlink". When "link" is clicked then a row the "tags" table (horrible name) is created with the feeds_id and categories_id values. (If it creates the same relationship ten times, that''s ok for now). The unlink would delete the corresponding row from the "tags" table. I followed the Apple demo and created http://code.google.com/p/ expenses/ , which has buttons kind-of along this line. However, it''s a one-to-many wheras I want a many-to-many. Plus, I think that the Apple tutorial is more than a little dated. Just thinking outloud. What kind of button would be sufficient for what I describe? I''m a bit more confident with how the show.rhtml interacts with methods, but: which method in which class for a "submit" type button? where does the button go? Just thinking out loud, and will be googling tomorrow :) -Thufir --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
