Get your git all setup and your project gitified.
Freeze your gems and freeze to edge your project and git push that to the server (rake rails:freeze:gems and rake rails:freeze:edge or rake rails:freeze:edge TAG=rel_2-0-2 see here ) (script/about to see what version your rails is already on. maybe you already froze earlier and forgot)
Capify your project (capify .)

To access data that has related data using has_many and belongs_to, first make sure you?ve set up your related ids. For example for the two models posts and attachments, the attachments table should have a field called post_id so that the attachment can be association to the post.
Then make sure you have the appropriate has_many and belongs_to in the models
Then do the following in your view code:
<% @posts.attachments.each do |post| %>
<img src="<%= attachment.public_filename %>" class="attachment" /><br />
<% end%>

To use the rails find method with conditional dates do the following. inspiration from here
Example:
Record.find :all, :conditions => {:date => 20070400..20070431, :user_id => current_user.id}
Or addition: Record.sum :hours, :conditions => {:date => 20070400..20070431, :user_id => current_user.id}
Now what if you want to use the current month instead of the static typed in months above?
this_month = Date.today.strftime("%Y%m")
start_of_month = this_month + '00'
end_of_month = this_month + '31'
result = Record.sum :hours, :conditions => {:date => start_of_month..end_of_month, :user_id => current_user.id} rescue nil
result = result.round(1) rescue nil
