# Rails user based custom field example with postgresql jsonb and using custom fields with ransack  

Demo: https://rails-custom-field-ransack.herokuapp.com

This example project for using custom field in rails. You can add new fields, and new resources related with your fields.

Virtual attribute for custom field:

```ruby

class Field

  include ActiveModel::Validations

  include ActiveModel::Conversion

  attr_accessor :name, :type, :key, :is_filter_exist, :is_sort_exist

  validates_presence_of :name, :type

  validates_inclusion_of :type, in: %w(number text)

  def initialize(attributes = {})

    self.is_filter_exist = false

    self.is_sort_exist = false

    attributes.each do |name, value|

      if name.in?(%w(is_filter_exist is_sort_exist))

        value = value.to_s.in?( %w(1 true) )

      end

      send("#{name}=", value)

    end

  end

  def persisted?

    false

  end

  def validate_key

    validates_length_of :key, maximum: 100

    validates_presence_of :key

  end

  def key_parameterize

    self.key = self.key.parameterize.underscore if self.key.present?

  end

  def as_json

      {

          name: name,

          type: type,

          is_filter_exist: is_filter_exist,

          is_sort_exist: is_sort_exist

      }

  end

end

```

PeopleController.rb

```ruby

class PeopleController < ApplicationController

  before_action :set_user

  before_action :set_fields

  before_action :set_person, only: [:show, :edit, :update, :destroy]

  def new

    @person = Person.new

  end

  def create

    @person = Person.new(person_params)

    @person.metadata = person_metadata_params

    if @person.save

      flash[:success] = 'Person created successfully'

      redirect_to user_person_path(@user, @person)

    else

      flash.now[:danger] = 'Invalid person parameters!'

      render :new

    end

  end

  def edit

  end

  def update

    @person.metadata = person_metadata_params

    if @person.update(person_params)

      flash[:success] = 'Person updated successfully'

      redirect_to user_person_path(@user, @person)

    else

      flash.now[:danger] = 'Invalid person parameters!'

      render :edit

    end

  end

  def show

  end

  def destroy

    @person.destroy

    flash[:success] = 'Person destroyed successfully'

    redirect_to @user

  end

  private

    def set_user

      @user = User.find(params[:user_id])

    end

    def set_person

      @person = Person.find(params[:id])

    end

    def set_fields

      @fields = @user.fields['person']

    end

    def person_params

      params.require(:person).permit(:name, :surname, :age, :email)

    end

    def person_metadata_params

      parameters = @fields.keys

      params.require(:person).permit(parameters).to_hash

    end

end
