So My Gemfile currently looks like
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.4'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets

# Use Uglifier as compressor for JavaScript assets

group :development, :test do

gem 'byebug'
end
group :development do

end
It works fine. Funny thing is, as soon as I remove mathjax-rails and try to run in production mode, I get

Why?! I just want to load MathJax from the MathJax CDN...
Even though you removed the gem, you might have some mathjax references left in your code. In the usage instructions for the gem, it seems like you have to add some code to routes.rb as well as app/views/layouts/application.html.erb. If those references are there, removing them should fix this sissue.

i think the problem is related to sqlite3 vs postgresql(heroku) but i cant seem to fix it.
here is the github link:
https://github.com/fawzi-saab/S-Portfolio
if you are especially creating apps to deploy heroku its better to use postgresql in both development and production. I look into your repo and i think your config/database.yml file needs to be revised in order to connect to postgresql database. You can also check a documentation to deploy an app to heroku here
I uses Rails but it does not follow the settings in config/database.yml.
With config/database.yml ($DATABASE_URL is the URL of my Heroku app's database)
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
adapter: sqlite3
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
url: <%= ENV['DATABASE_URL'] %>
I ran rails g controller hoge, then I got errors:

My ruby version is v2.5.0 and OS is macOS Sierra 10.12.6.
Why the adapter is set to postgresql in spite of sqlite3 in config/database.yml?
How can I use the configurations correctly?
I think of migrating developing environment to virtual box (to avoid cumbersome problems like this), but I am afraid that, in the box, I would get such errors as well. Is it OK?
Rails is using the connection details from the environment variable, not the config file. Rails uses both ENV['DATABASE_URL'] and config/database.yml when setting up the database, and in most cases the environment variable has priority.
Take a look at the docs to see how the two ways of configuring the database interact.
The simplest solution in your case is probably to remove the DATABASE_URL varaible from your development machine. It’s unlikely you need it set there, and could possibly cause problems if you accidentally connect to the production database from development.
You could also use the url: key rather than the database: key when specifying the development database, as that key does take precedence over the environment variable. It would look something like:
development:
<<: *default
url: sqlite:db/development.sqlite3
You should also probably remove the adapter from defaults, as you are not using sqlite in production but are merging in that key. What you have will likely work (since the environment variable overrides the setting in the file), but it is confusing. Ideally you would want to look into using the same database in development and production to minimise differences between the two environments.
I'm using the gem countries to populate a country select element. I'd like to add custom countries to the list of ISO3116 countries provided by the gem.
Gem: https://github.com/hexorx/countries
I've read the wiki for the countries gem. I've attempted to follow the instructions provided under the section 'Loading Custom Data'. unfortunately their too sparse for a relative to rails newcomer like myself.
When I try to boot up a development server, I get the error listed below.
I don't know where I should be adding the following code. I've added it to 'config/initializers' because according to the guides (http://guides.rubyonrails.org/initialization.html) files in this directory are loaded after the gem files are loaded when initializing the app. Hence, my confusion. By the time the code below is executed, shouldn't the constant 'ISO3116' have been initialized?
Code:
config/initializers/custom_countries.rb
ISO3116::Data.register(
continent: "Europe",
alpha2: "EN",
alpha3: "ENG",
name: "England"
)

Thank you,

PS. This is my second (maybe third) question I've asked on StackOverflow. Feedback welcome.
FML.
My approach is correct (well, it works). The code can be placed in config/initializers, my error was due to an incorectly formatted hash being passed into:
ISO3166::Data.register()
Hope this helps.
I'm getting an error when I try to boot up WeBrick.
When I type rails server, I get the following error:

Can anybody help me fix this?
PS: I am running on Windows 10
Try adding this line to your Gemfile
gem 'rack', '~> 1.6.4'
and then run:
bundle install
and see if that fixes your issue.
Update
If the above does not work, try uninstalling railties gem. Then install an older version of the rails (rails version 4.0.0 was used in the from the tutorial). The issue is due to the version mismatch/incompatibility of some of your gems.
I am getting this error when trying to deploy my application on a linux server.

You've updated this app from an older, 2.x version of Rails. You have a line in your config/initializers/new_rails_defaults.rb that uses the ActionController::Routing constant, that constant no longer exists in Rails 4.2.
So, basically, the fix here is to upgrade your app to 4.2 properly. I could tell you to remove the ActionController::Routing line from your file, but probably that's just one of many other issues you haven't fixed here.
The weird thing here is that you haven't mentioned having the same problems in dev, which suggests you're not actually using the version of Rails in dev that you think you are.
Good luck.
