I was trying to install the Ruby Gem Devise and I stupidly overlooked a step. I included the gem in my gemfile then ran the bundle install on the prompt. Then I forgot to run the generator rails generate devise:install.
Then when I went to generate my User model it came up with the following error C:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/2.2.0/gems/activesupport-5.1.4/lib/active_support/inflector/methods.rb:269:inconst_get': uninitialized constant User (NameError)`
I've tried uninstalling the gem and removing anything that refers to Users and reinstalling the gem but it keeps coming up with the same error.
I'm hoping someone can maybe shine a bit of light on this issue
I've just fixed the issue. When you run the bundle install command, it automatically configures the routes folder, so I've removed any reference to devise and it's worked now

I am trying to get a simple tutorial app up and running with Rails, but have run into this problem almost right away. I create the new ruby app, cd to the directory and run rake db:create. I get the following
Please install the sqlite3 adapter: 'gem install activerecord-sqlite3-adapter' (sqlite3 is not part of the bundle. Add it to the Gemfile.)
But I do have the gem added to the Gemfile, like so:
gem 'sqlite3'
Also, when I tried to gem install the adapter, I was given an output saying that it did not exist in any repository. This is my first time using rails, any ideas on how to fix this?
*Edit
gem install activerecord-sqlite3-adapter produces the following:
Error: Could not find a valid gem 'activerecord-sqlite3-adapter' in any repository.
The it offers some alternatives, only one of them being sqlite3. It is called activerecord-jdbcsqlite3-adapter. Is this the one I need possibly?
Thank you for everyone's input. I never was able to resolve this issue, and ended up just using the Rails Installer instead. So much easier, just make sure you delete all your previous versions of Rails, Ruby, Gems, everything. Then use the installer.
I am super, super new at programming and I have been trying to get everything set-up on my computer. I have installed RailsInstaller, go to >railsinstaller_demo, and type in rails s. I get the following error though could not find gem 'uglifier <>= 1.0.3> x86-mingw32'
I looked through the forum and found how to do a gem list and i noticed it was not there. I then went to gembundler and ran $ gem install bundler. I tried again but it did not work.
I am sure the answer is on this site, but i am so new that i see all these lines of code I actually have no idea where to type it in.. I am running Windows 7.
thanks for taking the time to help out a real beginner.
Have you gone to the $ railsinstaller_demo directory and run the bundle install command? This will install the gem dependencies for the application; you will not be able to run the server until you've bundled the gems. Additionally, if you're still having issues with the uglifier gem, go ahead and remove the line in the Gemfile and then run bundle install
If you need further help with the Command Prompt, you an find out more at http://bit.ly/ZajVeW.

I'm having this error message come up during Capistrano deployment. It implies to me that something's wrong with Rails being installed or something? Rails is not currently installed on the server side, but it's in my Gemfile (and my Gemfile.lock), so I'm assuming it should be installed during the bundle install command that gets executed before this line.
The actual command that's giving the error is:
bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile
I guess the problem is just that Rails is not being installed during the bundle install. Am I missing something?
Thanks!
UPDATE 1: Rails appears to be installing correctly via the bundle install command. If I check out the directory .../shared/bundle/ruby/1.9.1/gems, I can see action mailer in there.
UPDATE 2: Running the command rake assets:precompile actually fails locally as well, so this doesn't have anything to do with Capistrano it would appear. Now I just have to figure out why the config object doesn't know anything about action mailer?
UPDATE 3: Hot on the trail. It looks like my installed version of actionmailer is 0.6.1 (?!), meanwhile all the rest of my Rails stuff is up at 3.2.9. bundle update refuses to update actionmailer past this version. I'm going to remove all of my gems and start fresh.
UPDATE 4: Deleted my entire gemset using rvm gemset empty. Then tried to run bundle again, and again it tries to get actionmailer 0.6.1. I think something is screwed up with bundler or something...
The problem ended up being that I had removed a dependency upon a specific version of Rails in my Gemfile. I just had gem "rails" in there. That seemed to completely botch the dependency calculations, because it was getting super-old versions of action mailer rather than getting a consistent version from all gems. Guess it's a bad idea to not specify an exact Rails version. Yikes!
#aardvarkk,
Thanks for posting this issue, I was having the same error with my installation of Rails 4.0.0 and the error was preventing me from running my rails server
This is while I'm trying to follow the Hartl Tutorial for RoR.
I added gem "rails", '4.0.0' to my gem file and now I'm able to run my rails server.
Thank you
I installed devise 1.1.rc0 and haven't been able to get it to work in my existing application.
I changed the gem file to gem 'devise' without specifying the version. Ran bundle install. Then ran rail destroy devise_install since that's the command I used to install it.
*Then when I tried to reintall with rails generate devise:install it gives me this error:
gems/activerecord-3.2.8/lib/active_record/dynamic_matchers.rb:50:in method_missing': undefined methoddevise' for # (NoMethodError)*
Ryan Bigg helped me figure out the above error was caused by the user model making a reference to devise, which after the uninstall causes an error. So I removed that reference.
Now I have this error.
gems/activesupport-3.2.8/lib/active_support/inflector/methods.rb:230:in `block in constantize': uninitialized constant User (NameError)
What is this referring to?
You're getting this error because Devise isn't configured, yet your model references it. Remove the call to the devise method (or comment it out) in any model that references it.
I found the same issue when upgrading from 1.8.7 and Rails 3.0.7 to 1.9.3 and Rails 3.2.8. The solution involves removing:
gem 'active_reload'
I installed rails on Windows7 using RailsInstaller (v2.1.0). I found the original rails was v3.2.1. After that, I "gem install spree". It seems the installation upgrades rails to v3.2.7. I mentioned that because before yesterday it was just 3.2.6. Every thing goes well under rails 3.2.6, but if I "spree install" a rails 3.2.7 app, I failed to access the default store's Cart. And get the error like this:
NoMethodError in Spree::OrdersController#edit
undefined method `password_salt=' for #<Spree::User:0x68438d0>
As I checking the database, yes, there is no "password_salt" but only "salt" in spree_users table.
Is there anyone else encountered this problem? I had taken almost half day on this problem. Did I miss something in the Spree path?
Thanks very much.
I think I had the exact same issue before, see if specifying spree gem version (assuming is 1.1.2) in the Gemfile and then running bundle update works
#Gemfile
gem 'spree', '1.1.2'
and later run
bundle update
See if it works!
