Okay, so I'm trying to deploy my app onto Heroku.
Both of the following pieces of code result in success:
RAILS_ENV=production bundle exec rake assets:precompile
rails assets:precompile
*It is frustrating that rails assets:precompile comes out successful individually but when trying to push it up to Heroku, it says that this command fails.
Though when I commit those changes and try
git push heroku master
I get the following error:
remote: Running: rake assets:precompile
remote: rake aborted!

I've been digging through many threads and have yet to find an answer, any help would be appreciated. Below is the file it's referencing.

# session. If you need permissions, you should implement that in a before filter.
# You can also supply a hash where the value is a boolean determining whether
# or not authentication should be aborted when the value is not present.
# config.authentication_keys = [:email]
# Configure parameters from the request object used for authentication. Each entry
# given should be a request method and it will automatically be passed to the

# ==> Configuration for :encryptable
# Allow you to use another hashing or encryption algorithm besides bcrypt (default).
# You can use :sha1, :sha512 or algorithms from others authentication tools as

# Require the `devise-encryptable` gem when using anything other than bcrypt
# config.encryptor = :sha512
# ==> Scopes configuration

# "users/sessions/new". It's turned off by default because it's slower if you
# are using only default views.
# config.scoped_views = false

# config.sign_out_all_scopes = true
# ==> Navigation configuration
# Lists the formats that should be treated as navigational. Formats like
# :html, should redirect to the sign in page when the user does not have
# access, but formats like :xml or :json, should return 401.

# ==> OmniAuth
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
# config.omniauth :github, 'APP_ID', 'APP_SECRET', scope: 'user,public_repo'
# ==> 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.
#
# config.warden do |manager|
# manager.intercept_401 = false
# manager.default_strategies(scope: :user).unshift :some_external_strategy
# end
# ==> Mountable engine configurations
# When using Devise inside an engine, let's call it `MyEngine`, and this engine
# is mountable, there are some extra configurations to be taken into account.
# The following options are available, assuming the engine is mounted as:
#
# mount MyEngine, at: '/my_engine'
#
# The router that invoked `devise_for`, in the example above, would be:
# config.router_name = :my_engine
#
# When using OmniAuth, Devise cannot automatically set OmniAuth path,
# so you need to do it manually. For the users scope, it would be:
# config.omniauth_path_prefix = '/my_engine/users/auth'
# ==> Turbolinks configuration
# If your app is using Turbolinks, Turbolinks::Controller needs to be included to make redirection work correctly:
#
# ActiveSupport.on_load(:devise_failure_app) do
# include Turbolinks::Controller
# end
end
database.yml (production part which seems to be working otherwise)
production:
adapter: postgresql
database: db/production.pg
These entries in config/webpacker.yml solved it for me:
default: &default
source_path: app/javascript
source_entry_path: packs
public_root_path: public
public_output_path: packs
Note: 1 entry was missing in my configuration (which caused the TypeError): "public_root_path"
I had the same issue. If you're storing environment variables with Rails's new credentials features you might forgot to set the RAILS_MASTER_KEY ENV variable on Heroku:
heroku config:set RAILS_MASTER_KEY=<your key>
You find that key by looking in your config/credentials folder.
I am currently working on an app which involves syncing of contacts on rails server. I am using redis server and sidekiq for performing contact syncing in the background. My database is mongodb and I am using mongoid gem as ORM. Workflow is a follows:
Contacts on the phone are passed to the rails server through app and then on the rails server, it is queued in the redis server.
Now cron job triggers sidekiq which connects to redis and completes the job.
One Job of sidekiq is as follows:
it has array of contacts(size upto 3000).
It has to process each of these contacts. By processing I mean make insert queries to DB.
Now the problem is that sidekiq takes insane amount of time to complete the job. On average it takes 50-70 sec to complete the job.
Following are the relevant files

How can I speed up the processing of jobs? I tried with permutation of increasing concurrency of sidekiq in sidekiq.yml and pool of mongoid.yml, but no help.
How do whatsApp and other messaging apps deal with contact syncing?
If some other info is required, please ask. Thanks.
EDIT: If not possible to answer this question, can anyone please suggest me other ways to sync the contacts on the rails server.
indexes to the rescue.
class ContactDump
index({status: 1})
end
class Person
index({h_m_num: 1})
end
Person might need more indexes depending on what your Person.get_number_digest does.
After adding indexes run

Also, do remove the puts, you don't need that on your worker and puts is hitting your performance badly, even when you can't see the output!
I am new to Ruby on Rails and am trying to make my first application. I am having issues though anytime I run any rails generate command. I get the following error

Even if I don't add the gem 'devise' into my Gemfile I still get that error. I even created a new application and get that error.
I have even tried the answers at undefined method 'devise' for User
Any idea how I can get rid of this error?
EDIT
I currently do not have any models
This happens because you missed the command:
rails generate devise:install
You need just comment all devise lines temporally (in routes.rb / user.rb) to not get raise.
And run command again.
This is the appropriate Order.
gem 'devise'
Run the bundle command to install it.
rails generate devise:install
rails generate devise MODEL
Here Model was created before the "rails generate devise:install".So you have to go back an comment everything that model created :
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
#devise :database_authenticatable, :registerable,
#:recoverable, :rememberable, :trackable, :validatable
end
and also this
Rails.application.routes.draw do
#devise_for :users
end
Now,Run "rails generate devise:install" and after that uncomment the above .
I ran into a similar problem with an existing project freshly checked out from a repo:
The specific missing files were:
config/initializers/devise.rb
config/locales/devise.en.yml
In this case, because the devise.rb was in the .gitignore list there was a config/initializers/devise.rb.example file that could be copied over.
Execute this following commands:
rails generate devise:install
rails generate devise MODEL
If devise is installed already and also generated devise model as above and still facing error.
Add this code to User.rb file in Models
class User < ApplicationRecord
extend Devise::Models
Running rails generate devise:install creates a config/initializers/devise.rb file.
You have to restart your server with Ctrl + C and rails s in order for a change in config file to take effect.
Otherwise you'll get the same error upon refreshing the page.
Or, like me, after adding:
gem 'devise'
to Gemfile, and running:
$ bundle install
you forgot to restart the server with Ctrl C and:
$ rails s
This is a little weird issue which I too ran into! Try to add extend Devise::Models in app/models/install.rb file as explained in the below link.
Hope this helps!
https://github.com/plataformatec/devise/issues/3877
rails g devise install != rails g devise:install
I ran into this problem as well.
Executing rails generate devise install (sic!) there was nothing that seemed not to have worked. The terminal output was:
$ rails g devise install
Running via Spring preloader in process 5422
invoke active_record
create db/migrate/20180306165306_devise_create_installs.rb
create app/models/install.rb
insert app/models/install.rb
route devise_for :installs
But I missed the semicolon. Reverting these changes and then executing rails generate devise:install (note the : between devise and install), everything worked out perfectly. Also you get a much more extensive output:
$ rails g devise:install
Running via Spring preloader in process 5218
create config/initializers/devise.rb
create config/locales/devise.en.yml
===============================================================================
Some setup you must do manually if you haven't yet:
1. Ensure you have defined default url options in your environments files. Here
is an example of default_url_options appropriate for a development environment
in config/environments/development.rb:
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
In production, :host should be set to the actual host of your application.
2. Ensure you have defined root_url to *something* in your config/routes.rb.
For example:
root to: "home#index"
3. Ensure you have flash messages in app/views/layouts/application.html.erb.
For example:
<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>
4. You can copy Devise views (for customization) to your app by running:
rails g devise:views
===============================================================================
I faced the same problem and rails generate devise:install didn't solve it.
All I did is to create devise.rb file under initalizer folder and I add and this solve it

# Set this configuration to false if you want /users/sign_out to sign out
# only the current scope. By default, Devise signs out all scopes.
# config.sign_out_all_scopes = true
# ==> Navigation configuration
# Lists the formats that should be treated as navigational. Formats like
# :html, should redirect to the sign in page when the user does not have
# access, but formats like :xml or :json, should return 401.
#
# If you have any extra navigational formats, like :iphone or :mobile, you
# should add them to the navigational formats lists.
#
# The "*/*" below is required to match Internet Explorer requests.
# config.navigational_formats = ['*/*', :html]
# The default HTTP method used to sign out a resource. Default is :delete.
config.sign_out_via = :delete
# ==> OmniAuth
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
# config.omniauth :github, 'APP_ID', 'APP_SECRET', scope: 'user,public_repo'
# ==> 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.
#
# config.warden do |manager|
# manager.intercept_401 = false
# manager.default_strategies(scope: :user).unshift :some_external_strategy
# end
# ==> Mountable engine configurations
# When using Devise inside an engine, let's call it `MyEngine`, and this engine
# is mountable, there are some extra configurations to be taken into account.
# The following options are available, assuming the engine is mounted as:
#
# mount MyEngine, at: '/my_engine'
#
# The router that invoked `devise_for`, in the example above, would be:
# config.router_name = :my_engine
#
# When using OmniAuth, Devise cannot automatically set OmniAuth path,
# so you need to do it manually. For the users scope, it would be:
# config.omniauth_path_prefix = '/my_engine/users/auth'
# ==> Turbolinks configuration
# If your app is using Turbolinks, Turbolinks::Controller needs to be included to make redirection work correctly:
#
# ActiveSupport.on_load(:devise_failure_app) do
# include Turbolinks::Controller
# end
# ==> Configuration for :registerable
# When set to false, does not sign a user in automatically after their password is
# changed. Defaults to true, so a user is signed in automatically after changing a password.
# config.sign_in_after_change_password = true

I am new to rails and mongodb. i have generated mongod model in my rails project name as Forum
when i am trying to add record using following commands in rails console
f = Forum.new
f.topic_name = "my_topic"
f.save
I am getting following error
Moped::Errors::ConnectionFailure: Could not connect to a primary node for replic
a set #<Moped::Cluster:25470936 #seeds=[<Moped::Node resolved_address=nil>]>
I am running mongod server on port 27017
following is my mongoid.yml file

what to do??
review the localhost map in your hosts file or try hosts as 0.0.0.0:27017.

When looking for user that doesnt exist, I am getting:
Mongoid::Errors::DocumentNotFound in UsersController#show
Problem:
Document(s) not found for class User with id(s) 22. Summary: When
calling User.find with an id or array of ids, each parameter must
match a document in the database or this error will be raised. The
search was for the id(s): 22 ... (1 total) and the following ids were
not found: 22. Resolution: Search for an id that is in the database or
set the Mongoid.raise_not_found_error configuration option to false,
which will cause a nil to be returned instead of raising this error
when searching for a single id, or only the matched documents when
searching for multiples.
However I am setting raise_not_found_error to false

Controller
# GET /users/1
# GET /users/1.json
def show
#user = User.find(params[:id])
render json: #user
end
* UPDATE **
fixed a null response (not in a json format) going out by doing this:
def show
#user = User.find(params[:id])
if #user.nil?
#user = []
end
render json: #user
end
your structure of yml is wrong
has to be -
development:
sessions:
options:
#raise_not_found_error has to be not here but see below
options: #strictly 2 spaces before
raise_not_found_error: false #strictly 4 spaces before not 6
so, raise_not_found_error parameter has to be child of development>options, not development>sessions>options
For me even correct indenting didn't work, what did is to create an initializer file called mongoid.rb in config/initializers/ and put this into it
Mongoid.raise_not_found_error = false
To save someone few minutes, if you are still having a problem and you are sure your mongoid.yml configs are correct, try to stop spring server as it seems to do a lot of caching!
$ spring stop
