Week of April 8 - April14, 2012
Lots of tidying up in the Rails source this week. It's amazing how much even a mature codebase can be improved when lots of people are nibbling away at it.
- 1a20683f adds enough relations to NullRelation to make it chainable with database methods, so you can use Post.none anywhere you could use Post.all.
FormBuilderclass gets an
indexmethod in 47cbfbb9. Here's the sample usage from the commit:
<%= form_for @person do |person_form| %> ... <%= person_form.fields_for :projects do |project_fields| %> Project #<%= project_fields.index %> ... <% end %> ... <% end %>
- 1bac04e85 optimizes the performance of
#delegate. It's a mildly-breaking change, though, in that you can no longer delegate to private methods.
- With ca0af822, you get an automatic index when using
belongs_toin migrations. That's nice; it would have saved me typing
add_indexabout eleventy-seven times by now.
