I'm trying to introduce dynamic_sitemaps over resources with friendly_id. The issue is the production rails (rake / rails c) doesn't see the slug method. I've try to specify it by force by specifying an attr_accessible :slug, but it doesn't help either.
$ rake sitemap:generate
Generating sitemap...
rake aborted!
undefined method `slug' for #<Article:0xa9e4d14>
The funny thing it works smoothly on the local environment, and it should not be so much different with the capistrano/rvm deployment.
The column exists in the DB and is used by the rails app itself (which works fine too).
Added: it should be tied to either the environment or the specific gem version issue, but I'm not sure which one is the trouble, and how to debug it. The same pair works good for a different project with a pretty similar libraries bundle.
As the capistrano always do the dirty work, I forgot about the RAILS_ENV environment variable - so the console and cron job tried to operate against the dev DB and obviously failed.

I saw this post:
Rails/ActiveRecord/SQLite3: Can't save records in test environment
And after upgrading my sqlite version to the very latest (3.7.17), I am still getting the following error:
ActiveRecord::StatementInvalid: SQLite3::SQLException: near "SAVEPOINT": syntax error: SAVEPOINT active_record_1
Any time I try to create anything at all. If all I do is load my fixtures, everything is fine.
I have confirmed that rails is using the updated sqlite3 version by running "rails db".
In my development environment, I can create objects all day long with no errors (I can even have an object create another object after create).
What is special about my test environment that this is happening? How can I fix it?
Edit:
If I delete my test database, and redo rake:db:create and rake:db:migrate, I still get the same issues.
Doing "rails console test" lets me use the test environment just fine, and I can create objects all day long and see existing fixtures. It's only when I type "rake test:units" that I get the errors... (originally I had errors, but one error was legitimate (I don't know why I wasn't getting it in the development environment, and the adapter error was because apparently you aren't supposed to do "rails console RAILS_ENV="test", so it was looking for an adapter for an envrionment called "RAILS_ENV=test")
Edit: When I type "gem uninstall sqlite3" it uninstalls. When I then type "bundle install" it has a problem reinstalling...working on it now.
/home/jenny/.rvm/rubies/ruby-1.9.3-p0/bin/ruby extconf.rb --with-sqlite3-dir=/usr/local/bin/sqlite3 checking for sqlite3.h... *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check
the mkmf.log file for more details. You may need configuration
options.
If I type "gem install sqlite3" separately, it works just fine, and then "bundle install" it works. However, "rake test:units" has the same errors.
Edit:
When I type "which sqlite3" it prints out "/usr/local/bin/sqlite3"
I wasn't even aware sqlite3 headers were a thing, so I doubt I installed them. I'll try to figure out how to confirm this and see if it helps.
Edit:
I don't see anywhere to download sqlite3 headers on the main site...just source and the precompiled linux binary. There doesn't seem to be a special header in the source, but even if there was, wouldn't it be included in the precompiled binary?
EDIT: link to bundler sqlite3 install error that don't happen when i manually install the gem
http://pastie.org/8063577
EDIT: Not a devise problem. I thought it was, but it turned out I was just creating another object in fixtures, not in the test code.
So, I can create devise User or any other type of object in fixtures all day long, but if I attempt to create one in the unit test, I get the save point error. Same thing for trying to save a fixture in a unit test.
Your problem is most likely related to the fact that you updated your local sqlite but after that you haven't reinstalled your sqlite3 gem.
I'd recommend you follow these steps:
Remove the corresponding line gem 'sqlite3' from your Gemfile
Run bundle install
Run gem uninstall sqlite3
Return the line gem 'sqlite3' to your Gemfile
Run bundle install one more time
If you simply gem uninstall and then bundle install, it will install the same version and dependencies that were recorded in Gemfile.lock. But since you're now using a different and more updated local version, it's safer to allow Bundler to install a new version if needed.
I've got an existing rails app, and I've added an ember front-end. I'm having trouble deploying the new version (which includes Ember for the first time) to Heroku.
The problem is that I'm unable to run rake tasks in production mode.
I discovered this when I tried to rake db:migrate on heroku. I got the following error:
rake aborted!
undefined method `handlebars' for #<Rails::Application::Configuration:0x00000004f0de90>/app/.bundle/gems/ruby/1.9.1/gems/railties-3.2.13/lib/rails/railtie/configuration.rb:85:in `method_missing'
/app/config/application.rb:60:in `<class:Application>'
I get the same error if I try to run any tasks locally in production mode, e.g.:
RAILS_ENV=production rake -T
the offending line, from config/application.rb:
config.handlebars.templates_root = 'ember/templates'
for various reasons, I had to move the ember templates down one file level. and it needs to stay there. everything works fine in development mode.
Any idea how I can fix this?
tried upgrading the ember-rails gem. this didn't help. (I'm using 0.12.0)
trick was to move ember-rails gem out of assets group
I've got 3 Rails 3.2 applications using the gem jquery-ui-themes. jquery-ui-themes uses scss for the image-path helper.
It works great on two of my applications, but the 3rd doesn't seem to compile the scss files in either development or production modes.
IOW, it sends this to the browser
background: #fcfdfd url(image-path("jquery-ui/redmond/ui-bg_inset-hard_100_fcfdfd_1x100.png")) 50% bottom repeat-x;
whereas the two working apps properly send
background: #fcfdfd url("/assets/jquery-ui/redmond/ui-bg_inset-hard_100_fcfdfd_1x100.png") 50% bottom repeat-x;
I've spent many hours trying to make the app that's broken as similar to possible to the two working apps as I can, but it's still failing.
My theory is that SASS is choking on something previous to redmond.css.scss. If so, there should be an error logged somewhere. Where do I find the error output from SASS?
Update:
I introduced a deliberate error into redmond.css.scss and I got a proper error dump. So I know that I'm correctly clearing the cache and actually running sass. Now to figure out why it's ignoring the image-path directives.
If you're looking for the answer to the question in the title, the answer is "the same way you get any other errors: they're in your log". To get a full backtrace, just point your browser at the asset: ie http://localhost:3000/assets/jquery-ui/redmond.css in my case.
Make sure you clear all your caches: rm -rf .sass-cache/ && rm -rf public/assets && rake tmp:cache:clear, as well as using ctrl-shift-r in your browser.
If you're looking for the answer for my real problem (image-path not working), make sure you have the proper Bundler.require line in your application.rb. The old Rails 3.0 doesn't work.
replace:
# If you have a Gemfile, require the gems listed there, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env) if defined?(Bundler)
with:
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
My rails 3 app always is stuck in the Test environment. When I call
rake db:reset
it resets the test database, but not the development one.
When I run the following code, it loads the test environment in the console:
rails c
Trying to specify the development environment also does not work:
jon#jon-laptop:~/id$ RAILS_ENV=development rails console
Loading test environment (Rails 3.0.8)
ruby-1.8.7-p334 :001 >
Starting the server does work normally:
rails s
This is very annoying. Any ideas on where I should look to resolve this?
Thanks in advance,
EDIT
I also tried going back in history to earlier commit to before the problem existed (I think) and it does not fix the problem...
The easiest way is to set the environment is probably by using the RAILS_ENV environment variable, e.g.:
RAILS_ENV=test rails console
Edit: Which version of Rails are you using? This works fine for me on 3.0.7:
rails c [environment]
E.g.
rails c development
I found the problem. I had the following lines in one of my initializers:
ActionMailer::Base.default_url_options[:host] = "localhost:3000" if Rails.env == "development"
ActionMailer::Base.default_url_options[:host] = "localhost:3000" if Rails.env = "test"
Can you spot the mistake???
I'm trying to create a custom model to interface with a database that isn't supported navtively by Rails or through the OpenLink ODBC driver. For some reason, I'm getting the following error:
no such file to load -- odbc
I'm at a lost as to why this is occurring as the ruby-odbc gem is in the GEM_PATH and I have a small script that tests this to ensure that the connection works and it worked perfectly. Does Rails ignore the gem_path? Is there something else I need to configure? I checked the GEM_PATH in Rails by writing it out to the browser and it matches what I saw in a terminal window.
FYI: I'm using rvm to manage ruby and all of my gems. Not sure if this makes any difference, though it really shouldn't from what I can tell.
Does your Gemfile include something like the following
gem 'ruby-odbc'
