Include with two references of one model of the same table
Hey guys,
I just came across this oddity, not sure what to make of it yet, but
I think it might be incorrect behavior. When doing a @inst.find(:all,
:include => ["hometeam", "awayteam"] ...) hometeam and awayteam are two
references from a belongs_to that is of the same model and of the same
table. I will get a pgerror stating that "matches", which is

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:

Rails bug? Conditions on associations ignored by eager loading
I''m looking for someone to confirm the following as a bug in Rails
1.0 before I post it to Trac.
If I use eager loading on an association that has conditions defined,
the conditions are ignored.
The following example illustrates the problem. I have two tables:
create_table "blogs", :force => true do |t|

MVC interplay to query multiple models
I''m trying to track down why I''m getting close to desired output, but not
quite. It looks like the webpage sorta-kinda is grabbing the right

fits, to a degree. However, it''s just grabbing the hexadecimal object

'puppet storeconfigs export' killed
Hi,
I currently have a MySQL database containing all Puppet storeconfigs. My
intention is to migrate to PuppetDB on a PostgreSQL server, so the first
step is to use the ''storeconfigs'' face to export all the DB to a file
PuppetDB can later consume. But the ''puppet storeconfigs export'' command
always ends up being killed, I suspect due to some sort of OOM

NewBie question
Hi,
I m very new to Ruby.
I bought a book "Ruby on Rails" and I think I understand some concepts.
My question is :
Is there a way to not use "Cookies" or "Sessions Variables" to keep some
information about the user.
I ask this question because I would like to prevent some cases where the
user browser won''t accept cookies.

'unknow column error' when using include and associated table condition in find
Here is my weird problem.
Two models like following:
Lexeme
id:int
name:string
Structure
id:int
ref_id:string
meta_id:int
Lexeme can have many structure records through foreign key ''ref_id'' in
the structures table.
And these structure records belonging to one lexeme differs between
each other using meta_id.
And if Lexeme has structures, then there must be a top_struct whose
