The below query fails: Timesheet.joins(:time_entries).select("timesheets.*, sum(time_entries.worktime) as total").group("timesheets.start_date") The models have the following relations: Timesheet < AR has_many :activities, dependent: :destroy, inverse_of: :timesheet has_many :time_entries, through: :activities accepts_nested_attributes_for :activities,

I have two models, links and tags, associated through a 3rd model, link_tags.

So this functionality isn''t supported natively in Rails 3 (or any versions before that for that matter) But I had found a work around via this blog post: http://geoff.evason.name/2010/04/23/nested-has_many-through-in-rails-or-how-to-do-a-3-table-join/ This didn''t work on Rails 3 because it wasn''t able to properly build the query from the join with symbols. I was

I''ve got a User model and a Book model. A user is required to submit books each month to be reviewed by other users. I have the following relationships defined: # the join model book_review.rb belongs_to :user belongs_to :book end book.rb # each book is reviewed by many users. This allows us to get the BookReview # objects associated with this book has_many :book_reviews,

I was wondering if anyone knew of a way to combine the new nested forms in rails 2.3 with a has_many through relationship via checkboxes. Basically I have a page model, a page_category model and a category_items join table. Pages have many page categories through category items. The category_items table is polymorphic so i can use it for other models who need categories (maybe this is

Dear R team, The following piece of code (to use the lsa package) works fine on my mac os x, but when I run the same code on Windows XP, it doesn't work any more. ### code: library("lsa") matrix1 = textmatrix("C:\\Documents and Settings\\tine stalmans.TINE. 000\\LSA\\cuentos\\", stemming=TRUE, language="spanish", minWordLength=2, minDocFreq=1,

Dear R users, Version 2.1-1 of the sem package, for structural equation modeling, is now on CRAN. Unlike version 2.0-0, which was a major overhaul of the package, version 2.1-1 just sprinkles some syntactic sugar on it, introducing the specifyEquations() and cfa() functions; specifyEquations() supports model specification in equation (rather than path) format, and cfa() facilitates compact

I've been looking at the weather vocabulary in asterisk-sounds in CVS. I've run into a few hitches with words I can't seem to find. So far, I'm looking for 'point' (for constructing floating point numbers) and 'around' as in "high around 70" (don't I wish). Any chance of getting these? While I'm on the subject, I'd be very interested in a

Hi all, If I was to start developing an application using Edge Rails with the view to deploying on Rails 1.1, would I fall foul of lots of bugs, or is it relatively stable? I''d really like has_many :through relationships, to save me dealing with HABTM + associations. Thanks, Tom

I have three tables products has_many :pricings pricings belongs_to :product belongs_to :pricing_group pricing_groups had_many :pricings I would like to have a single page where I can add/edit a product and on the same page administer the pricing for that product for each pricing group.

Hi, I haven''t done any associations before, so please forgive my incorrect use of terminology... If I set up a has_many :through association, can I manipulate the associated instances directly (like an Array), or do I need to manipulate the join model? For example, suppose I have two classes and the associated join model: class foo has_many :foo_bars has_many :bars, :through
