Hi I followed the Sunil tutorial but I'm getting the following db error:

Migration file:
class CreateProjectTranslations < ActiveRecord::Migration
def up
::Refinery::Projects::Project.create_translation_table!({:description => :string},
:migrate_data => true)
remove_column :refinery_projects, :description
end
def self.down
add_column :refinery_projects, :description, :string
::Refinery::Projects::Project.drop_translation_table! :migrate_data => true
end
end
after running the migration the I realize is not not creating the the translation table for projects.
Model:
module Refinery
module Projects
class Project < Refinery::Core::BaseModel
self.table_name = 'refinery_projects'
translates :description
attr_accessible :name, :description, :date_started, :date_conclusion,
:position, :relevance, :img_id, :project_id, :status
validates :name, :presence => true, :uniqueness => true
has_many :project_images
has_many_page_images
class Translation
attr_accessible :locale
end
end
end
end
what I'm I missing here?
I solved this issue moving the migration file from the extension to the app migration folder. After that the application was able to create the table for the translation.
Below is a command to generate the extension. If to use it on an existing one, it`ll add all required code to already existing files by overriding them. Be careful with that - commit files before.
rails g refinery:engine Service title:string description:text icon:image --i18n title description

Error
Here's the error that I encountered when I'm testing my Account changeset. It seems like it would only be caused by the Ecto migration with wrongly structured database, but the ecto.migrate runs fine, as also Postgresql doesn't throw any error when I'm trying to insert a row using a similar changeset below.

Thanks guys. What happened in my case is that because I changed migrations after using ecto.migrate, so that the migration changes differs between the test database and development database.
I just ran MIX_ENV=test mix ecto.reset to sync database between the environments.
I have a web app in which I have the following relationship between two tables, a Topics and Categories table in which a Category has many Topics and a Topic belongs to a Category.
class Topic < ActiveRecord::Base
has_many :comments, dependent: :destroy
belongs_to :category
belongs_to :user
validates :subject, :body, :user_id, :category_id, presence: true
private
def self.find_by_id(params)
if params[:topic_id]
find(params[:topic_id])
else
find(params[:id])
end
end
def self.build_topic_comment(params, comment_params)
#topic = Topic.find_by_id(params)
#topic.comments.build(comment_params)
end
def self.load_comments(topic)
topic.comments.build
end
end
class Category < ActiveRecord::Base
has_many :topics, dependent: :destroy
belongs_to :user
validates :name, :user_id, presence: true
private
def self.find_by_id(params)
if params[:category_id]
find(params[:category_id])
else
find(params[:id])
end
end
def self.load_topics_desc(category)
category.topics.order(created_at: :desc)
end
def self.build_category_topic(params, topic_params)
#category = Category.find_by_id(params)
#category.topics.build(topic_params)
end
end
I added the functionality to move a topic to a different category by updating a topic's foreign key called category id. This is done trough an admin panel I coded myself and it is working correctly. When I checked the topics index page he category column is indeed updated.
The issue is that the rspec test I created is failing and giving me the following error:
Admin::TopicsController with administrator access PATCH #update with valid attributes updates a topic
Failure/Error: if #topic.update(topic_params)

else
render :edit
end

params.require(:topic).permit(:subject, :body, :category_id)

Can someone point me in the right direction in regards to why the tests could be failing and the app is working correctly?
Thanks!
I am getting the following postgres error:

I'm a newbie and I got some trouble when run rails 3 server with mongodb (using mongoid) in production mode. Everything is ok in development mode, and I cannot figure out what am I missing. Please help me, thank you very much. This is the error:
ActionView::Template::Error (undefined method `map' for nil:NilClass):

this is my action:

end
end
my model:

config.assets.compile = false
config.assets.digest = true
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
end
And the second thing is I cannot get anything from db although everything is work well in development mode. If you have any suggestion, please help, thanks.
