switch user -- users list click any user for session create

Please visit the above doc :

https://github.com/flyerhzm/switch_user
======================================

Add Gem:

gem "switch_user"

=======================================
If you need to override the default configuration, run rails g switch_user:install and a copy of the configuration file will be copied to config/initializers/switch_user.rb in your project.

rails g switch_user:install

===========================================

Add file for controller:

app/controllers/switch_user_controller.rb

class SwitchUserController < ApplicationController
  def set_current_user
  user = User.find(params[:scope_identifier])
                # without devise
  if user.present?
  session[:user_id] = user.id
  redirect_to '/'
  end
                # with devise 
  # sign_in(user)
  end

  def remember_user
  end

end

==============================================

config/routes.rb

get 'switch_user', to: 'switch_user#set_current_user'

  get 'switch_user/remember_user', to: 'switch_user#remember_user'


=============================================

Add Link for Button:

1. Activeadmin Users index page
   
     column "Switch User" do |show|
        links = link_to 'Login As', "/switch_user?scope_identifier=#{show.id}"
     end

2. simple rails users index
   
    <%= link_to 'Login As', "/switch_user?scope_identifier=#{user.id}"%>
==============================================

Require jquery cookie js:

//= require jquery.cookie.js

$(".module_close").on('click', function() {
    $(".module_hide").addClass('hidden')
    $.cookie('the_cookie', 'hide information');
    console.log($.cookie('the_cookie'))
  });
  $(".fa_info_click").on('click', function() {
    $(".module_hide").removeClass('hidden')
    $.cookie('the_cookie', '');
    console.log($.cookie('the_cookie'))
  });

$(window).on('load',function() {
  if ($.cookie('the_cookie') != ''){
    $(".module_hide").addClass('hidden');
  }
});

404 page

Please visit site:

https://mattbrictson.com/dynamic-rails-error-pages

rails generate controller errors not_found internal_server_error

This creates app/controllers/errors_controller.rb with corresponding view templates in app/views/errors/ for the not found (404) and internal server error (500) pages. (Ruby methods declared with def can’t start with numbers, so use the spelled-out error names instead.)

2SEND THE RIGHT STATUS CODES

class ErrorsController < ApplicationController
  def not_found
    render(:status => 404)
  end

  def internal_server_error
    render(:status => 500)
  end
end

Normally Rails sends an HTTP status of 200 OK when it renders a view template, but in this case we want 404 or 500 to be sent according to error page being rendered. This requires a slight tweak to the errors_controller.rb that Rails generates. You don’t need to specify the name of the template to render, because by convention it is the same as the action name.

3CONFIGURE THE ROUTES

match "/404", :to => "errors#not_found", :via => :all
match "/500", :to => "errors#internal_server_error", :via => :all

Rails expects the error pages to be served from /<error code>. Adding these simple routes in config/routes.rb connects those requests to the appropriate actions of the errors controller. Using match ... :via => :all allows the error pages to be displayed for any type of request (GET, POST, PUT, etc.).

4TELL RAILS TO USE OUR ROUTES FOR ERROR HANDLING

config.exceptions_app = self.routes

Add this line to config/application.rb. This tells Rails to serve error pages from the Rails app itself (i.e. the routes we just set up), rather than using static error pages in public/.

5. config/environments/development.rb:

config.consider_all_requests_local = false

Login with username

Please visit site:

https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-sign-in-using-their-username-or-email-address

Create a migration:

rails generate migration add_username_to_users username:string:uniq

Run the migration:

rake db:migrate

User.rb:

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable, authentication_keys: [:login]

attr_writer :login

validates :username, presence: :true, uniqueness: { case_sensitive: false }
  validate :validate_username

def login
    @login || self.username || self.email
  end
  def self.find_for_database_authentication(warden_conditions)
    conditions = warden_conditions.dup
    if login = conditions.delete(:login)
      where(conditions.to_h).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first
    elsif conditions.has_key?(:username) || conditions.has_key?(:email)
      where(conditions.to_h).first
    end
  end
  def validate_username
    if User.where(email: username).exists?
      errors.add(:username, :invalid)
    end
  end
=========================================================

Modify config/initializers/devise.rb to have:

config.authentication_keys = [ :login ]

Application.rb

config.exceptions_app = self.routes

Modify the views


sessions/new.html.erb:


  -  <p><%= f.label :email %><br />
  -  <%= f.email_field :email %></p>
  +  <p><%= f.label :login %><br />
  +  <%= f.text_field :login %></p>



Use :login and not :username in the sessions/new.html.erb


registrations/new.html.erb:


  +  <p><%= f.label :username %><br />
  +  <%= f.text_field :username %></p>
     <p><%= f.label :email %><br />
     <%= f.email_field :email %></p>



registrations/edit.html.erb:


  +  <p><%= f.label :username %><br />
  +  <%= f.text_field :username %></p>
     <p><%= f.label :email %><br />
     <%= f.email_field :email %></p>

Configure Devise to use username as reset password or confirmation keys

Simply modify config/initializers/devise.rb to have:

config.reset_password_keys = [ :username ]
config.confirmation_keys = [ :username ]

Password update

Routes.rb :

resources :users do
    collection do
      patch 'update_password'
    end
  end
  get 'change_password' => "users#change_password"


users_controller.rb :

def change_password
    @user = current_user
  end
  def update_password
    @user = current_user
    unless @user.valid_password?(params[:user][:current_password])
      @user.errors.add(:base, "Current Password is incorrect.")
      return render "change_password"
    end
    if @user.update(user_params)
      # Sign in the user by passing validation in case their password changed
      bypass_sign_in(@user)
      redirect_to root_path
      #redirect_to destroy_user_session_path
    else
      render "change_password"
    end
  end

uploading big image for inginx

Following link:

https://stackoverflow.com/questions/26717013/how-to-edit-nginx-conf-to-increase-file-size-upload

/etc/nginx/nginx.conf

Now that you are editing the file you need to add the line into the server block, like so;

server {
    client_max_body_size 500M;

    //other lines...
}

If you are hosting multiple sites add it to the http context like so;

http {
    client_max_body_size 500M;

    //other lines...
}

And also update the upload_max_filesize in your php.ini file so that you can upload files of the same size.

PREVIEW AN IMAGE AND VIDEO BEFORE IT IS UPLOADED

Please take a look at the sample JS code below:

<script type="text/javascript">

  function readURL(input) {

    if (input.files && input.files[0]) {

    var reader = new FileReader();

    reader.onload = function (e) {

    $('#blah').attr('src', e.target.result);

    }

    reader.readAsDataURL(input.files[0]);

    }

  }

  $("#imgInp").change(function(){

    readURL(this);

  });

</script>

and the associated HTML:

<div class="field">
    <%= form.label :image %>
    <%= form.file_field :image,  id: "imgInp" %>
    <img id="blah" src="#" alt="your image" style="height: 150px; width: 200px;" />
  </div>
