Ruby On Rails 3.2.3 - Displaying Information From Two Models On The Same View -

-

i trying display country name on view. have user model country_id belongs_to :countries. have country model id, iso & name has many :users.

this have in controller show view: @user = user.find(params[:id])

i thought relationship setup user.country.name or user.countries.name , country name. following error, both in view or in user controller. not matter if have user, country or countries capitalized or not.

failure/error: click_button "save changes" actionview::template::error: undefined local variable or method `user' #<#:0x007fb9548a7ae0>

i thought try in view: country.find(@user.country_id).name

this works expected in rails console. showing correct country id value want name for. stated when command in rails console correct value. in console first assigned @user in controller. afterwards country.find command. in view following error on country.find command:

failure/error: click_button "save changes" actionview::template::error: couldn't find country id=1

when display value looks this:

#<country:0x007ffd6bf9ac20>

i same error when created instance variable @country_name set country.find command. i'm lost because united states record has id = 1 in country , can find in rails console.

i have checked web, including stack overflow. similar question showing information 2 models has been asked number of times here. have not been answered except 2 options tried cannot work. once can working create user helper this.

here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
