find_by_ issue
In the Agile RoR book, page 219 (softcover version) they talk about the fact you can use the methods: find_by_ and find_all_by_ and fill in the last piece with a valid column name. So I have a database table called "parts" and the following columns: id partname partnumber vendor I do the following: (connection to DB already established) class Part < ActiveRecord::Base end

AR's find_by_* limits return results. How to avoid id?
When I use find_by_name method I get LIMIT 1 result. > SELECT "users".* FROM "users" WHERE "users"."age" = 25 LIMIT 1 But the "age" column is not unique in my table and its value may repeat.

Retrieving Mutliple Records using find_by_*
I was hoping that AR''s find_by_* magic methods would help me retrieve multiple items somewhat like the following: names_to_find = [''Larry'', ''Moe'', ''Curly''] found_people = Person.find_by_name(names_to_find) Is there a way to accomplish this using find_by_* (or even find(:all) using some sort of conditions) or must I resort to SQL

find_by_email dynamic method returning new
Hello everyone, I have a rails app which uses email as login name. At some point, I have to search the user, in the User model by email. For some reason, the method User.find_by_email(email) returns nil, even though the user is in the database. The same applies for any find_by_* method that searches by any database column. I was able to find the user using the User.find Does anyone have an idea

Is find_all_by deprecated and/or find_first_by for 2.0.2? If not, what is actually deprecated? just find_all(..) and find_first()?

updating the db 6000 times will take few minutes ?
i am writing a test program for ActiveRecord, and it reads a document which is like 6000 words long. And then i just tally up the words by recordWord = Word.find_by_s(word); if (recordWord.nil?) recordWord = Word.new recordWord.s = word end if recordWord.count.nil? recordWord.count = 1 else recordWord.count += 1 end recordWord.save and so this part loops for 6000 times... and it takes a few minutes to run at least...

ActiveRecord: Behavior not doumented
Hello everbody, doing a #find(:first,an_id) with Rails 1.1.0 I expected that find returns the record which id mathches the given parameter an_id or nil if it couldn''t be found. This behaviour is documented on api.rubyonrails.org. But the find returns the first available object and not nil if an_id is not in the db. Is the doc on rubyonrails.org out of sync?
