rails 2.3 convert hash into mysql query - mysql

Question

I'm trying to find out how rails converts a hash such as (This is an example please do not take this literally I threw something together to get the concept by I know this query is the same as User.find(1)):
{
:select => "users.*",
:conditions => "users.id = 1",
:order => "username"
}
Into:
SELECT users.* FROM users where users.id = 1 ORDER BY username
The closest thing I can find is ActiveRecord::Base#find_every
def find_every(options)
begin
case from = options[:from]
when Symbol
instantiate_collection(get(from, options[:params]))
when String
path = "#{from}#{query_string(options[:params])}"
instantiate_collection(format.decode(connection.get(path, headers).body) || [])
else
prefix_options, query_options = split_options(options[:params])
path = collection_path(prefix_options, query_options)
instantiate_collection( (format.decode(connection.get(path, headers).body) || []), prefix_options )
end
rescue ActiveResource::ResourceNotFound
# Swallowing ResourceNotFound exceptions and return nil - as per
# ActiveRecord.
nil
end
end
I'm unsure as to how to modify this to just return what the raw mysql statement would be.

Answer 1

So after a few hours of digging I came up with an answer although its not great.
class ActiveRecord::Base
def self._get_finder_options options
_get_construct_finder_sql(options)
end
private
def self._get_construct_finder_sql(options)
return (construct_finder_sql(options).inspect)
end
end
adding this as an extension gives you a publicly accessible method _get_finder_options which returns the raw sql statement.
In my case this is for a complex query to be wrapped as so
SELECT COUNT(*) as count FROM (INSERT_QUERY) as count_table
So that I could still use this with the will_paginate gem. This has only been tested in my current project so if you are trying to replicate please keep that in mind.
