I have a dataset, which contains a day column that I would like to retrieve results on. Is there any reason why daily_stats.where(''day = Date(?)'', dte).first returns and empty set, daily_stats.find(:first, :conditions => [''date(day) = ?'', dte]) returns the correct data and daily_stats.where({:created_at => (date.midnight - 1.day)..date.midnight}).first

Need some advice. I''ve got two modules: artists and paintings. In my home page, I''ve got a 2nd page that says "Browse paintings", which displays ALL paintings of ALL artists. This is being rendered by paintings#index. In another page, I should show all paintings of a specific artist ONLY. Meaning, paintings from ONE artist. I cant use paintings#index for this anymore

Hi list, how are ya? So, my current project is just begging for the ability to have parameterized associations in my ActiveRecord classes. Basically I need something that is a cross between named scopes and standard associations (has_many specifically). I''m wondering if such a thing exists or, if not, if anyone else has an elegant, equivalent solution? Example: class Sprocket <

Hey guys, I''m trying to merge a hash with another using the .merge! function. class User < ActiveRecord::Base serialize :preferences end This is what I end up with in the console: >> u = User.find(1) >> u.preferences.merge!{:test => 1} SyntaxError: compile error (irb):32: syntax error, unexpected tASSOC, expecting ''}'' u.preferences.merge!{:test

Artist.first.medias returns all medias. Media is an STI. Media can be video or painting. How do I return all paintings of an artist? Only paintings, not videos? In my Artist model, I tried putting: has_many :paintings, :through => :medias In console, I do: Artist.first.paintings.all And I get: ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source

Hello all! I have a conundrum that I''m _sure_ someone else has already thought of and solved. How does one best handle the scenario of association object changes and data integrity? For example, if I have a standard ecommerce site that sells Products and people can have Orders and an Order has_many Products... then, what happens if Product #3 is part of Order #2 but at some point, the

The setup is a follows: The table is a shared partial of Controller1 and Controller2 accessible via "shared/table". The AJAX''ed sorting using the sort helper works all fine on

Hi guys, Thanks for your answers on my two questions yesterday. That's exactly what I was looking for, sorry for not noticing it myself, but I'm still getting acclimated to Asterisk and even Linux--from what I see so far, I love it. I've got another one now. Since my Asterisk install and configuration is fairly stable at this point, I'm interested it ensuring that during

ParaSail (http://parasail-lang.org) is a safe pervasively-parallel object-oriented programming language. Starting in June 2014 we began the construction of an LLVM-based backend for ParaSail. The existing ParaSail interpreter is broken into a front end that generates instructions for the "ParaSail Virtual Machine" (PSVM), and an interpreter for PSVM instructions. The LLVM-based

Hi Everyone, We're routing calls through Asterisk (dialing in via sip and then dialing out via SIP). We've noticed a curious behavior in chan_sip that doesn't persist with chan_pjsip. When examining the packet capture, we're seeing the SSRC changing constantly on the call. At first it happens over a variable interval (15s 6s etc) but eventually it ends up changing exactly every

Hi, I have a dell poweredge 850 with centos 4, freshly installed. I'm now trying to add in a fibre -> sata raid enclosure with LSI HBA's in the 850. My problem is the enclosure gets detected first, hijacking sda and sdb from the internal SATA drive and causing kernel panic at boot time. I've tried changing the order in modprobe to the following: alias eth0 tg3 alias eth1
