Hey all, I am starting to create my sites in Ruby on Rails these days instead of PHP. I have picked up the language easily but still not 100% confident with associations :) I have this situation: User Model has_and_belongs_to_many :roles Roles Model has_and_belongs_to_many :users Journal Model has_and_belongs_to_many :roles ...
Hello world! We have a form to submit ratings for a certain restaurant in a in our views/restaurants/show.html.erb. We only want logged in users to create new ratings.

I often use respond_to do |format| ... end in Rails for my Restful actions, but I don't know what the ideal solution is for handling various forms of, say, html responses. For instance, view1 that calls action A might expect back html with a list of widgets wrapped in a UL tag, while view2 expects the same list of widgets wrapped in a...
Hi everyone, I was hoping I could get feedback on major changes to how a model works in an app that is in production already. In my case I have a model Record, that has_many PhoneNumbers. Currently it is a typical has_many belongs_to association with a record having many PhoneNumbers. Of course, I now have a feature of adding tempora...
I can't get the following SQL query to work quite right in Rails. It runs, but it fails to do the "HAVING row_number = 1" part, so I'm getting all the records, instead of just the first record from each group. A quick description of the query: it is finding hotel deals with various criteria, and in particular, priortizing them being pa...

Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_d...

So I am going over some basic guides in Rails, reviewing the basics and such for an upcoming exam. One of the guides included was the sort-of-standard getting started guide over at guide.rubyonrails.org. Here is the link if you need i...

Maybe I do not understand the space well enough to teach the nuances. Redirecting him to Martin Fowler' article or the google ranked one InfoQ or other material has not helped muc...

For instance, consider the following base model: # Content only has one property named path class Content < ActiveRecord::Base se...
I have a site that on only certain occasions (and so far I have only seen this using Safari 4 on Mac) does not load a page correctly, so the underlying HTML code shows up.
