I clone rails app (our company project) and then install everything that related to mongo db and mongoid gem. Then I run the rake db:setup and then rails s. Its working fine, I can access all the sites and do everything. But I got problem in the rails console.
Whenever I do this:
rails c
then
User.first
I will get this error
Loading development environment (Rails 4.1.1) irb(main):001:0>
User.first Mongoid::Errors::NoSessionConfig: Problem: No
configuration could be found for a session named 'default'. Summary:
When attempting to create the new session, Mongoid could not find a
session configuration for the name: 'default'. This is necessary in
order to know the host, port, and options needed to connect.
Resolution: Double check your mongoid.yml to make sure under the
sessions key that a configuration exists for 'default'. If you have
set the configuration programatically, ensure that 'default' exists in
the configuration hash. from

I have been looking all over google and some blogs, could not figure it out how to fix this.
Besides that, we dont use the Rspec tho.
change your config/application.rb file:
replace it Bundler.require(*Rails.groups)
to it Bundler.require(*Rails.groups(assets: %w(development test)))
In the latest mongoid -5.0.0 version you can simply solve by placing the below code in application.rb
config.generators do |g|
g.orm :mongoid
end
In config/application.rb change
Bundler.require(*Rails.groups)
to:
Bundler.require(:default, Rails.env)
Rails is trying to eager load the group of gems by environment and the stock config/mongoid.yml file you get when you run rails g mongoid:config only gives you a test and development namespace. Even though you're only running development, it's looking at all the groups. If you add the production namespace to the yml file it will load but my answer above works without you needing to do that.
Just make sure that on application initialization you do the following (in Rails console)
Mongoid.load!("path/to/your/mongoid.yml")
For more details visit http://mongoid.org/en/mongoid/docs/installation.html
With MongoId version 5.x, You will change config in Rails application follow:
File: application.rb
# Add line.
config.generators do |g|
g.orm :mongoid
end
I was set it and it working in rails console.
See more at:
https://docs.mongodb.com/ecosystem/tutorial/mongoid-installation/#rails-applications
may be The problem is in the gem file, you did't mention the version of mongoid gem.
in gem file change
gem "mongoid"
to
gem "mongoid" , '~> 4.0.2'
and run bundle install
restart server and console.

I am currently writing a website with Ruby on rails for a few months.
Suddenly (5 or 6 days ago), all the commands like rails db:migrate, rails db:rollback, rails db:*" don't work anymore (and it does not seem to have touched anything...).
I tried to reinstall the gems rake, rails and railsties (which were already in their latest versions) but the problem still persists.

This happens probably due ruby version upgrade.
Try to install the gems again with bundle install and then try again.
If don't work you'll need to run as bundle exec rails db:migrate for bundle pick the right version of the gems.
EDIT: since your are using rvm, make sure you're using the same Ruby versions. Take a look at this https://rvm.io/workflow/projects and make sure you're in the right version.
Hint: Check the Ruby version in the Gemfile, as it could be the source of your problem.

checked my devise.rb
the only line i added was
config.omniauth :facebook, FACEBOOK_CONFIG['facebook_api_key'], FACEBOOK_CONFIG['facebook_api_secret'], scope: "email, publish_actions"
and this is my gemfile - as you can see i have the production and development information included
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
as advised devise 230-238

# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
config.omniauth :facebook, FACEBOOK_CONFIG['facebook_api_key'], FACEBOOK_CONFIG['facebook_api_secret'], scope: "email, publish_actions"
# ==> Warden configuration
# If you want to use other strategies, that are not supported by Devise, or
# change the failure app, you can configure them inside the config.warden block.
You probably want to stop using this magick FACEBOOK_CONFIG variable and start using environment variables for heroku
config.omniauth :facebook, ENV['FACEBOOK_API_KEY'], ENV['FACEBOOK_API_SECRET'], scope: "email, publish_actions"
to get this ENV working on development easier please check:
https://github.com/bkeepers/dotenv
or
https://github.com/laserlemon/figaro
It looks like the issue is with Devise.
the error says
undefined method `[]' for nil:NilClass
If you look at the next line down it is coming from.
config/initializers/devise.rb:234
So the error is on line 234 in config/initializers/devise.rb.
Run the following command on your mac.
bundle exec rake assets:precompile
If you don't get the same error, then you know that it is an issue with your production environment.
Can you add what you have on line config/initializers/devise.rb:234
Obviously FACEBOOK_CONFIG that you're trying to use is nil.
First you have to set the two environment variables in your Heroku account:
$ heroku config:set FACEBOOK_API_KEY=your-key-here
$ heroku config:set FACEBOOK_API_SECRET=your-secret-here
Then verify these are set correctly:
$ heroku config:get FACEBOOK_API_KEY
$ heroku config:get FACEBOOK_API_SECRET
Finally update the device.rb file as follows:
config.omniauth :facebook, ENV['FACEBOOK_API_KEY'], ENV['FACEBOOK_API_SECRET'], scope: "email, publish_actions"
Now should be good to go.
Just update your facebook.yml file with same information for production. I guess you only have development.
/config/facebook.yml
development:
facebook_api_key: copy_from_here
facebook_api_secret: copy_2_from_here
production:
facebook_api_key: paste_to_here
facebook_api_secret: paste_2_here

i am using the require statement to get the dynamic values from the form to schedule the job. Please help to solve this issue?
Note: i have seen the following stackoverflow queries:
How to detect Rails environment inside whenever
Following this thread to get dynamic values, but facing problem with require statement.
Rails - Whenever gem - Dynamic values
Ruby/Rails - Whenever gem - Loop cron tasks
config file in schedule.rb with Rails Whenever gem?
Whenever doesn't require or depend on Rails at all, so when it runs, RAILS_ROOT is not defined, however because whenever's schedule.rb is generally kept in /config/schedule.rb, we can make an assumption that it is in a rails project, and set our own RAILS_ROOT like this:
# in schedule.rb
RAILS_ROOT = File.dirname(__FILE__) + '/..'
Edit: in the case that you actually need Rails loaded, do this:
# in schedule.rb
# this will require config/environment and load your entire rails environment
require File.expand_path(File.dirname(__FILE__) + "/environment")
The whenever developer already answered this question, check this out https://github.com/javan/whenever/issues/81
Javan Whenever no longer attempts to load your Rails environment. However, it does automatically set a path variable to the directory whenever was executed from. This should work just the same:
set :output, "#{path}/log/cron.log"
In Rails 4 try with:
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
in your schedule.rb file.
This way you also have access to all your active-record models and initializers.

Looking at that log output you've now posted, it looks like you have haven't formatted that .yml file correctly. The use of whitespace in YAML is absolutely critical. Indent with spaces, not tabs, and make sure your indentation is consistent within each level. It appears that the lines are all aligned differently in your file, which is causing syck (the YAML parser) to throw an Exception.
EDIT | You also want to make the spacing between the key, the semi-colon and the value consistent too. Take pride in the layout of your code and you'll enjoy coding more ;) But pride or not... YAML is (intentionally) picky about whitespace.
Have your yml files properly indented and you will not be getting syntax error anymore.
Also add mysql2 compatible version in your Gemfile, so that while you will be deploying it to any server it will take from Gemfile automatically.
Did you add "mysql" to your Gemfile and run "bundle install"?
If you're working on Windows, I know that I didn't have the MySQL C Driver installed on my machine. It's a different download than the MySQL Community Server. You also have to make sure that your PATH has the route to the C driver. Download the driver here.
