[Rails] Re: Active Record has_one through

Turns out the event table needed to have an artist_id column. I was attempting to use the join table without a reference to the artist table. I dont know if that was the fix, because i also wrote a function in the event model that used the artist_id to return artist data from the database.

Re: [Rails] one liner with rescue is good style ?

rqstate is as follows, if there is not a quote request or the status field is null then we could assume that the request was never submitted to the backend api. This was actually the first time I tried this approach but I am not sure I will keep it this way def rqstate

Re: [Rails] one liner with rescue is good style ?

Re: [Rails] one liner with rescue is good style ?

[Rails] Where do I put plain old Ruby objects?

Hey all, I've been doing rails for a couple years now but this is my first time in the mailing list. My question is this: I've got a little objects housing some data, more or less like a struct with an initializer. What is the "Rails way" regarding arbitrary objects like this? Do I just
