I could use some eyes on
https://rails.lighthouseapp.com/projects/8994/tickets/4368
if anyone has the time.
Summary of the change:
Similar to PredicateBuilder's existing support for 'table.column' =>
'value', this patch enables 'column#method' => 'value'.
For instance, Article.where('title#matches' => 'Hello%') generates SQL
like:
SELECT "articles".* FROM "articles" WHERE ("articles"."title" LIKE
'Hello%')
Among other things, this change would prevent it from being necessary
to resort to SQL strings in order to achieve something as simple as a
a "published_at is not null" where clause.
Article.where('published_at#noteq' => nil).to_sql
SELECT "articles".* FROM "articles" WHERE ("articles"."published_at"
IS NOT NULL)
It plays nicely with scopes:
scope :published, where('published_at#noteq' => nil)
In general, I don't see a whole lot of downsides to this... One thing
that could perhaps be improved is the elimination of quote
requirements around hash keys by method_missing on Symbol
(:table.column), and an operator for method selection
-- :column/:method maybe? I don't know, that syntax looks a bit goofy,
too. I chose the # of its relationship to Object#method. Most likely
for the same reasons the new routing strings were chosen.
Thanks,
Ernie
