search for: find_by_

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 mypart = Part.f...

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. So I expect that an array of records where "age" is 25 will be...

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(:...

...account id or transaction id between the controller and the view. But what is to stop someone hacking the URL or view html to access another account id or transaction id ? eg /account/show/46 becomes /account/show/53 or /transaction/show/44 becomes /transaction/show/77 Well, I can change every find_by_* to include the account id from the session [is this safe, ie, what about cookie hacking?] What other techniques are people using to cope with ''id'' hacking?

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 of what might be going on? thanks, -fred -- You received this message becau...

...of two possible ''state'' values (passive || pending_singup). While trying to implement this I discovered that the find_or_(initialize| create)_by_* dynamic finders totally and silently ignore any conditions passed. Bug? Should''nt these dynamic finders behave the same as find_by_* or find_all_by_* dynamic finders and use the :conditions passed to them? The documentation seems to indicate that they should. http://api.rubyonrails.org/classes/ActiveRecord/Base.html Dynamic attribute-based finders "It''s even possible to use all the additional parameters to find...

i am writing a test program for ActiveRecord, and it reads a document which is like 6000 words long.

...ve a UI element which allows users to toggle whether or not to display deleted Pages, their current setting being stored in a session variable, session[:show_deleted]. What we would like is to automagically have :with_deleted => session [:show_deleted] appended to all calls to find, all, first, find_by_ etc. That would be easy enough to do with an alias_method_chain but for the fact that session data is not available when the call is being made from a model. I know accessing session data in a model is controversial, but can anyone suggest a workaround? Or alternatively another approach to being...

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?
