but when i run "rake db:migrate" on my computer it run fine. can anybody help me please. i work with rails 4.0.0, ruby 2.2.3, Postgres SGBD and i'm in linuxmint 17

my migration :

class CreateOptions < ActiveRecord::Migration
  def change
    create_table :options do |t|
      t.string :config_key
      t.string :config_value

      t.timestamps
    end
  end
end

my model :

class Option < ActiveRecord::Base
   class << self
   def get_config_value(key)
      c = find_by_config_key(key)
      c.nil? ? nil : c.config_value
    end


    def set_config_values(values_hash)
      values_hash.each_pair { |key, value| set_value(key.to_s.camelize, value) }
    end

    def set_value(key, value)
      config = find_by_config_key(key)
      config.nil? ?
        Option.create(:config_key => key, :config_value => value) :
        config.update_attribute(:config_value, value)
    end

    def get_multiple_configs_as_hash(keys)
      conf_hash = {}
      keys.each { |k| conf_hash[k.underscore.to_sym] = get_config_value(k) }
      conf_hash
    end

  end
end

Answer 1

I solved my problem. In effect heroku first checks the model before setting up the database and at the level of my class options i created a subclass that inherited options that's where the error came from. I first removed this heritage, executed the migrate, and then restored it and walked it. thank you
