Hello, I''ve been using Rails for years, including has_many :through and eager loading, but this one has me stumped. The problem is that Active Record is only eager-loading the first of many records. Here are the models (note set_table_name for a legacy schema): class Tag < ActiveRecord::Base set_table_name ''tag'' end class DishTag < Tag has_many

Hi, I have a many-to-many relationship between dishes and ingredients class Dish < ActiveRecord::Base has_and_belongs_to_many :ingredients end class Ingredient < ActiveRecord::Base has_and_belongs_to_many :dishes end I have a join table dishes_ingredients now when i access my_dish.ingredients, i get a list of what looks like Ingredient objects, but the but they don''t have

Hello all. I have the following Code in a view: <% @dishes.each do |dish| -%> <tr> <td><%= link_to dish.name, :controller => "restaurant", :action => "show_dish", :id =>"#{dish.id}" -%> <% if dish.vegetarian? -%> <%= image_tag("/images/vegetarian.gif", :class => "bevel", :size => "8x8")

Hi all, I have two data frames that one of them does not have the column ID: > str(data) 'data.frame': 499 obs. of 608 variables: $ ID : int 1 2 3 4 5 6 7 8 9 10 ... $ alright : int 1 0 0 0 0 0 0 1 2 1 ... $ bad : int 1 0 0 0 0 0 0 0 0 0 ... $ boy : int 1 2 1 1 0 2 2 4 2 1 ... $ cooki : int 1 2 2 1 0 1 1 4 2 3

It's not what I want, the first data frame has 499 observations and the second data frame is a subset of the first one but with 375 observations.

Rails make it easy to start a new application. At the same time, import a new project into Subversion is not that simple -- there are quite few files that should be ignored. I used to manually remove added log files and tmp/cache, tmp/sessions, tmp/sockets files after the import and then go through the painful process of setting svn:ignore properties. There is an easier way -- simply

I have a new server with multiple nics running Centos 6.2 and I'd like to force all NFS traffic over one nic. We're using FreeNAS to dish out NFS shares and I have different IPs on my 2 nics but how can I get the server to mount the share over one particular nic? Or is there a better way to do it? Thanx, Russell Smithies

Respected Sir/Madam, I have a question regarding calculation of LD50 (Lethal Dose) and IC50 (50% inhibitory concentration) of an antimicrobial experiment. I have used a compound isolated from a plant and observed its effect on the fungus *Fusarium oxysporum* by the food poisoning method. Solutions of the compound at concentrations of 0, 50, 100, 150, 200 and 250µg/ ml were added to

Hi, We have the following shares listed in smb.conf users cannot access the samba share directly i.e. \\sambaserver\rixilr or \\sambaserver\bridges error messages '/ibe/dusty/RIXILE Share/Bridges' does not exist or permission denied when connecting to [bridges] Error was Permission denied Aug 21 10:09:12 dish sambaserver[27859]: [2015/08/21 10:09:12.964101, 0]

Hello RoRsters'', I''ve just started my first project with ROR, and frankly it''s pretty amazing, there are many things that still haven''t "clicked" for me yet but essentially it''s all coming together. My first project is a basic blog application to replace a current Moveable Type based blog. I''ve managed to get the basic functionality

Samba version : samba-4.1.12, AIX 6.1, compilation(configure, make clean install) was ok. but smbd not starting. gdb --dbx /opt/samba/sbin/smbd /root/core Core was generated by `smbd'.

I''m doing the depot example in the Agle Web development book. I''m getting this error: "undefined method `product'' for #<BigDecimal:331ce70,''0.21E1'',8(8)> " "Extracted source (around line #9): 8: for item in @items 9: product = item.product 10: -%> 11: <tr> 12: <td><%= item.product%></td>"

I want to use something similar to the following: @total_price += { product.price <> nil ? product.price : 0.0 } This fails in rails with a "nil can''t be coerced into Float" error. What is the (most) correct way to do this? On a related issue, what is the significance of the value 40 following "cart.rb" in the trace snippet below? The entire class file

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Hello, With high microphone gain, I seem to have problem making the silence detection work. The speech detection works well for the rare dish sample, which has very low noise amplitudes in silence regions. However, if the microphone gain is set to really high, noise samples are taken as speech, as indicated by the non-zero return value from speex_encode() calls. I had VAD turned on.

Hi, I've been doing an experiment, measuring the dead-zone-diameters of bacteria, when they've been grown with paper diffusion disks of antimicrobial. There are two groups, or treatments - one is bacteria that have been cultured in said antimicrobial for the past year, the other group is of the same species, but lab stock and has not gone had any prior contact with the antimicrobial.

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

I''ve finally gotten lighttpd working for my production instance (SUSE 10.0 with SSL). (Had to install the fcgi dev toolkit, the SUSE 10 ruby-fcgi rpm, and the fcgi gem. I''m not positive all 3 were required, but that is what I did.) Now the devel instance of my app is broken. I''m not sure how to fix it. Previously I was using WEBrick for both devel and production.
