ActiveRecord delete_all With Sanitized Parameters?
Hi there
I''m trying to delete a set of active record objects based on certain
conditions. I''d like to do something like the following:
Context.delete_all("uri IN (?)", uris)
But delete_all doesn''t allow multiple arguments. Since I don''t have
the IDs for the objects I want to delete, I can''t use delete(id), and
have resorted to this,

Delete_all causes a deadlock on MSSQL database ???
Hi all,
When i use the ''delete_all'' function to remove a few rows from my
database, it causes a deadlock on the sql server. The delete seems to be
successful, it then redirects to the ''view'' page, and the record does
appear to be deleted as far as the ''view'' rails page shows.
BUT if i go into sql query analyser, i can''t do a

Creating performance test fixtures from development db? How?
Hi all!
I''m looking into the testing chapter of Agile Web Development With Rails
(2nd ed.).
I want to performance test my app, but I''m too lazy to write fixtures for
performance test.
I''d rather use the data from my development db (because the data is so close
to the production data).
How do I get the data into the test db without writing fixtures?
Could you please

Capgemini.

Understanding :dependent => :delete_all?
I can''t see what''s wrong here but that''s probably just because I''m so
new to Rails! To get right into it... I have 4 tables that look like
this:
Sites
- id
Projects
- id
- site_id
- user_id
Tasks
- id
- project_id
- user_id
Users
- id
The corresponding models:
class Site < ARB

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

Model.delete_all vs Model.destroy_all in a habtm
Hi there
I have an habtm association between 2 Models.
I regularly have to truncate the table on one side of the relationship
and repopulate the table with a fresh csv file.
I notice that f I do Model.delete_all, none of the records in my habtm
join table get deleted, whereas if I use destroy_all they do.
However, the overhead of using destroy_all is too great. For the
amount of records I have

In a find, can''t you use both :include and :limit ?
I''m trying to do a find that includes a join. It has to be a find
because I''m using the results for a Pagination, so I need to limit my
query to the number of results I want to display per page.
Here''s the type of thing I want to do:

has_and_belongs_to won't delete records
Hi,
I have a has_and_belongs_to relationship between 2 objects, order and
product. I''m getting a foreign key violation when trying to delete
Order. Is there a special way of deleting orders without deleting
products? ("has_many" has :dependant => :delete_all.... does
"has_and_belongs_to" have something similar)

Problem with migrations
I am trying to start my first project after going though the Depot

and even with changing the name of the second table and other minor tweaks
it just does not work. I am connected to the db, the first table does get
filled out.

New Technique: Subsets of has_many Associations
I just now thought of this, and sure enough it works like a charm (at
least so far in my limited testing):
has_many :events, :dependent => :delete_all
has_many :upcoming_events, :class_name => "Event", :conditions =>
"date > NOW()"
The purpose of this is that it makes eager loading of subsets of
associations possible without replacing all the magic of the

is it possible to check that associated taggings are being destroyed

associations, I want to test that I have specified the association as
a dependent one.

how to delete all document from the DB (without deleting the DB itself)
Hello,
I'm still testing PHP5 bindings and I could'nt find a way to delete
all documents from a DB without deleting other informations stored in
the DB such as synonyms.
Since the process of adding synonyms is time consuming, I would like
to use the same DB but restart my test without any document in the DB,
is this possibile?
I could'nt find a delete_all or a method like that, nor
