Hi, I''ve been googling and going through the forum, and I can''t find the answers so some stray questions. A) If I have a render :partial is there a way to get rid of the trailing newline? <%- and -%> don''t work. Is the <br> an essential part of the partial? B) People say that the mysql tables get kinda messy sometimes and that they need to be reinitialized every once in a while. Frankly, that kind of talk scares me. But what are the steps for reinitializing? I have a problem where I added the has_many and belongs_to lines fairly late in the game, and I am worried that somehow the scaffolding isn''t paying attention to them. I have an object that has_many As and has_many Bs. It gives me no problem with the As, but when it tries to find the Bs, give an error. The error says: uninitialized constant SpreadType::Abstractleg I don''t have any irritating pluralization or nothin. I am running on Debian Linux. 3. I also get a scary error when I try to install the ruby-gems debugging package. Should I just switch OSes? What is the VERY BEST OS for doing ruby work? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You can use PostgreSQL, Oracle, MS Sql Server, whatever works best for you.> > I have a problem where I added the has_many and belongs_to lines fairly > late in the game, and I am worried that somehow the scaffolding isn''t > paying attention to them.Scaffolding doesn''t care about associations, and it''s really not meant to be anything but a learning tool.> I have an object that has_many As and > has_many Bs.

Generally, if project has_many :tasks, and task belongs_to :project, then the tasks table would have a project_id column. The belongs_to declaration goes in the model whose table contains the foreign key.> > I am running on Debian Linux. > > > 3.

What is the VERY BEST OS > for doing ruby work?Debian is a fine OS, but I don''t know how you installed things. Its packages for Ruby might be out of date. Ubuntu is a good distro for development. I''ve used Ubuntu, Windows, and Mac, and I prefer the Mac OS for Rails development. Not going to get into the reasons because I don''t want to start a holy war. But given that your installation has recent versions of Ruby (ruby -v should report 1.8.4 or higher, preferably something in 1.8.6 or so) then you should be fine.> > -- > Posted via http://www.ruby-forum.com/. > > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

And here is the index file
<% for spread_type in SpreadType.find_spread_names%>
<%= spread_type.name %>
<%
# this loop works
for customer_subscription in spread_type.customer_subscriptions
%> <%= customer_subscription.customer_id %>

# this loop does not work
# for ghostleg in spread_type.ghostlegs

If you want multiple divs side-by-side, you''ll need to use the appropriate CSS to position them that way.> A friend of mine who is a mid-level rails developer thinks it might be > impossible to avoid the breaks.Rails does wonderful stuff, but it doesn''t absolve *web* developers from the need to know HTML and CSS.

Thank you fred: That was it. I had created it with the plural, and then was treating it as though I had created it with the singular.
