...9;m creating more noise than I should. I want to know the easiest way to deal with this scenario: I have articles. I have categories for the articles. On the form where you write an article, there needs to be a free-form field to entire the category. The create() method will build the article, find_or_create_by_name the category, and assign it to the article. After that, the article is saved. I need to display an error if the category isn''t included, and I need it to act like a normal form error: add its message to the list of errors, and highlight the field. Does anyone know an easy way to do...

...ttp://stackoverflow.com/questions/11257662/can-i-make-rails-update-attributes-with-nested-form-find-existing-records-and-ad I haven''t seen a better answer than one I propose myself but I''d like to know if it''s possible to enhance accepts_nested_attribute_for to allow a find_or_create_by behavior for the one-to-many associated collection, instead of always creating new records.

...nd_or_intialize_by_country_id(@country) Since the artist doesn''t exist yet, there will be no ''id'' attribute yet. However, I have to pass in an id to the url which creates the song, ie: new_song_path(@artist) This will obviously fail since @artist.id is nil. I can use find_or_create_by instead, but then if the user cancels creating a song, I will be left with an extra row in the artist table that I don''t need. Any ideas?

I am interested in:- *If there is person exist, it should skip insertion into people table but data should be inserted in songs and

....find_by_user_name is actually Person.find_by_user_name(user_name, options). So you could call Payment.find_all_by_amount(50, :order => "created_on"). The same dynamic finder style can be used to create the object if it doesn''t already exist. This dynamic finder is called with find_or_create_by_ and will return the object if it already exists and otherwise creates it, then returns it." Here are a couple of examples. I know these are contrived since I could use ''find_or_initialize_by_name_and_state()'' however what I am really trying to show is that the :conditions...

Hi Folks, There is much discussion where I work at present regarding migrations, and the ''correct'' usage or not of them. TL;DR Should migrations be used just to modify schema, and other ''deploy'' tasks done other ways? If yes, how to ensure no repeat runs of such tasks (seeds, jobs etc) Background Once you''re live there are often additional things
