A new, minimal Sphinx gem for Rails
Howdy all,
I wanted to share this blog post we just published at Harvest:
http://www.getharvest.com/blog/2011/03/thebes-a-new-minimal-sphinx-gem-for-rails/
If any of you are doing work involving clusters of Sphinx servers or
with Sphinx under Rails 3, we think this gem is a pretty great fit. The
approach is to use ERB templating to configure Sphinx instead of a DSL.

A "strict Arel" mode for ActiveRecord to prevent SQL injection vulnerabilities
Hello rubyonrails-core,
I’ve been looking into possible changes to ActiveRecord / Arel to make it
easier to write Rails applications that are free of SQL injection
vulnerabilities, and in particular do so in a way that makes it easy for a
code reviewer to verify that the app is safe from such bugs.
The concern:

With the ActiveRecord API as is, it’s relatively easy to write

Arel Union does not support #order or #limit
I just posted this ticket in Lighthouse, but thought perhaps some

This forum has helped me to progress but I''m confused by one thing.
My app is supposed to allow seaching for results depending on the check
boxes that are checked. In my case, when the user checks a determined
facility and clicks "search" the corresponding hotels with only those

ActiveRecord and ARel: correlated subqueries?
I''m trying to figure out how to use ActiveRecord in conjunction with
ARel. In particular, I''d like to replace my residual literal SQL with
ARel, if only I could see how.
Let''s take Article with multiple Versions as an example. With ARel
alone, I can find articles with their latest versions like this
articles = Article.arel_table
versions = Article.arel_table

Issue with Arel::SelectManager and insert Method
Hello,
Arel::SelectManager (arel 2.0.9) uses following statement to insert a
new record:
@engine.connection.insert im.to_sql, ''AREL'', primary_key_name,
primary_key_value
But in DatabaseStatements insert ist defined as:
insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil)
Actually, Arel::SelectManager does not use the sequence name. This

Surprise in (delete_all | clear | destroy_all) on association
Hi,
I was very surprised by difference of delete_all on association vs
model(delegated to relation).
Given TaskFilter.has_many(:qualifiers, :class_name=>''TaskFilterQualifier'')
TaskFilter.delete_all => one DELETE statement
Without :dependent option on "qualifiers" association
TaskFilter.first.qualifiers.delete_all =>
SELECT `task_filter_qualifiers`.* FROM

RoR - Search Forms with Checkboxes, display appropriate results

The question is, I want to add checkbox fields for each facility I have
and in the search form, when the user selects

Remove ActiveRecord::Relation#& alias for 'merge' ? (or at least only reference and not use in AR)
Would the core team be open to the removal of the ''&'' alias for
ActiveRecord::Relation#merge?
The reason is that in Ruby the ''&'' operator refers to an intersection
of two sets of data, not a merge. (within the context of the Array
class)
Recently Arel added support for SQL Set Operators:

Puzzled with form on multiple table rows
I''ve got a table of events, and each event has a boolean attribute
is_ten_event.
On each row of the table is a chekbox to edit the value of is_ten_event,
so that multiple rows can be edited with one submit.
In order to allow boxes to be un-checked as well, the logic in the
controller works like this
get array of events from checkboxes that are ticked.

Hi all,
I''ve been playing around with Arel this week (actually outside of Rails)

OT? Using Arel to generate table names in multiple self join query
Firstly I''m sorry if this is off-topic but I think it''s a question
that won''t be answered without good core knowledge.
I have written a multiple self join query something like this:

:joins => { :children => { :children => :children } },

Is it possible? What is the best place to find info/examples on how to do
it?
