I encountered the following problem with MongoID.
I've created two models which related by one to many.
require 'mongoid'
class User
include Mongoid::Document
has_many :configs
field :login, :type => String, unique: true
field :password, :type => String
field :email, :type => String
end
class Config
include Mongoid::Document
belongs_to :user
field :links, :type => Array
field :root, :type => Array
field :objects, :type => Array
field :categories, :type => Array
end
After that I've created new User instance:
user = User.new
user.login = "login1"
user.password = "password1"
user.email = "email1"
user.save
But I saw the following output:

If I remove the lines with "has_many" and "belongs_to" then the program will work correctly.
Can anyone tell what am I doing wrong?
Looks like there's some kind of collision with your Config class and one that might already be defined. Try changing the name of the model to something like UserConfig.
Or you can use a wrapper module to namespace your classes:
module MyApp
class Config
...
end
class User
...
end
end

PageObject.register_widget :main_menu, MainTabsWidget , :ul
I have a page called landing page that uses the widget in the following manner....
class LandingPage
include PageObject
include PageObject::PageFactory
main_menu(:menu_tabs, :id => 'mainMenu')
def select_menu_item(item)
menu_tabs_element.go_to_tab_item item
end
end
This actually did work at one point. If you pass 'First' for select_menu_item, it will click to the page specified by first_link. If you specify 'Category/Subcat1' it will click on the category link and then subcat1.
Howerver, something changed. We are transition from watir-webdriver gem to watir (6.10) gem, and now the code gets the argument exeption
'ArgumentError: wrong number of arguments (0 for 1..2)'
This occurs when menu_tabs_element gets referenced in any way. I've run out of ideas to remedy this.

It is not clear to me which change in Watir would cause this issue. It seems more likely a change in Page-Object. At any rate, here are 2 solutions. Note that this was tested with Page-Object v 2.2.4.
Using Widgets
As pointed out by Alexis in Page-Object Issue 263, including page object accessor methods in widgets is not as straight forward as one would expect. In the MainTabsWidget class, instead of include PageObject, you need to do:
extend PageObject::Accessors # to get the accessor methods
attr_reader :platform # the accessor methods don't work without a platform
With this change, your page object should work.
Using Page Section
Page-Object has a page section feature that might better suit your needs. It simplifies some of the code (ie address the above issue).
You define a class to represent your main tabs section. Note that you do not need to register the section or have the multi-line setup as with Widgets.
class MainTabs
include PageObject
include PageObject::PageFactory
link(:first_link, :text => 'First')
link(:second_link, :text => 'Second')
link(:third_link, :text => 'Third')
link(:category_link, :text => 'Category')
link(:subcat1_link, :text => 'Subcat1')
link(:subcat2_link, :text => 'Subcat2')
def select_menu_item(tab_item)
items = tab_item.split /\//
items.each do |item|
case item
when 'First'
first_link
when 'Second'
second_link
when 'Third'
third_link
when 'Category'
category_link
when 'Subcat1'
subcat1_link
when 'Subcat2'
subcat2_link
end
end
end
end
The page object can simply become:
class LandingPage
include PageObject
include PageObject::PageFactory
page_section(:menu_tabs, MainTabs, :id => 'mainMenu')
end
The clicking of the menu would change to:
page.menu_tabs.select_menu_item('First')
(or you could continue to define a #select_menu_item method in LandingPage to avoid downstream changes)
I've been trying to implement the association at FrontEnd but as currently the application in not having any database directly connected with the website, so as a result we can not use the ActiveRecord and only using the ActiveModel for supporting the validations and core features of a Model. Now as we need to use the nested attributes which we are going to send along with an object, the addresses which are associated with the User, so for this we need to first define the association on the corresponding model. But after defining the association it is throwing exception of undefined method "has_many" on User model. I'm currently searching the way to implement it in our website and implement the logic of nested attributes.
It would be great if you can suggest me anything related to this or if you have met with such issue in the past.
I've also tried the approach using the gem https://github.com/softace/activerecord-tableless but not working for me. Also I've added a tableless.rb
tableless.rb
class Tableless < ActiveRecord::Base
def self.column(name, sql_type = nil, default = nil, null = true)
columns << ActiveRecord::ConnectionAdapters::Column.new( name.to_s, default, sql_type.to_s, null )
end
def self.columns()
#columns ||= [];
end
def self.columns_hash
h = {}
for c in self.columns
h[c.name] = c
end
return h
end
def self.column_defaults
Hash[self.columns.map{ |col|
[col.name, col.default]
}]
end
def self.descends_from_active_record?
return true
end
def persisted?
return false
end
# override the save method to prevent exceptions
end
But getting the following exception Exception:

It seems that you forgot to call the method
has_no_table
On your model, as per https://github.com/softace/activerecord-tableless#usage. In their example:
class ContactMessage < ActiveRecord::Base
has_no_table
column :name, :string
column :email, :string
validates_presence_of :name, :email
end
Hope this helps. =)
I'm writing a client for a web service, and part of their model is a list of strings belonging to a user containing previous usernames the user went by. I'm trying to use DataMapper for my client gem, and my first thought was to use DataMapper's has n syntax, but I can't seem to apply this to Strings. Is there a better way of doing this perhaps?
My current code:
class User
include DataMapper::Resource
# Some Properties here
has n, :also_known_as, 'String'
end
The error this generates is this:

why do you use 'String' here?
has n, :also_known_as, 'String'
it make no sense, remove it:
has n, :also_known_as
if you want to set model, use :model option:
has n, :also_known_as, :model => ModelName
and i'm not sure you want to use String as model name.
most likely you need an extra model to keep user's previous names:
class UserAlias
include DataMapper::Resource
# ...
end
class User
include DataMapper::Resource
# ...
has n, :also_known_as, :model => UserAlias
end
If you want to be able to search for older usernames via the datamapper 1.x query DSL you need to define an additional model.
class User
include DataMapper::Resource
# ...
has n, :also_known_as, :model => UserNameHistory
end
class UsernameHistory
include DataMapper::Resource
property :id, Serial
property :name
belongs_to :user
end
If you do not need to query via the old usernames you can use a serialized large object. As a suggestion you could use the DataMapper::Property::YAML from dm-types like this:
class User
include DataMapper::Resource
# ...
property :also_known_as, YAML
end
I have a model

and in the rails console I have no problem doing
FactoryGirl.create :post
to get a valid object and am able to access the *published_date* attribute. However in my spec
require 'spec_helper'
(1..5).map do |i|
title = "a title\t#{i}"
escape_title = "a_title_#{i}"
perma_link = "/posts/#{i}/title/#{escape_title}"

I'm totally stumped on it. Any ideas
Brad
Did you run rake db:test:prepare? It looks to me like your Post model has published_date, but your Factory is saying it doesn't exist. Not running this rake task would be the major thing that would cause this.
Been at this for a while. If i tell Category to just create, everything works fine. If I tell it to find_or_create I get errors.
These work:
puts topic.at_xpath("#topicid")
puts topic.at_xpath("#topicname")
and
Category.create!(:topic_id => topic.at_xpath("#topicid"), :name => topic.at_xpath("#topicname"))
But these don't:
Category.find_by_name(topic.at_xpath("#topicname"))
or
Category.find_or_create_by_topic_id_and_name(topic.at_xpath("#topicid"), topic.at_xpath("#topicname"))
Where am I messing up?
class FeedEntry < ActiveRecord::Base
require 'nokogiri'
require 'open-uri'
has_many :category_feeds
has_many :categories, :through => :category_feeds
accepts_nested_attributes_for :categories, :allow_destroy => true, :reject_if => proc { |obj| obj.blank? }
def self.nokogiri_get_feed
url = "http://some_feed.com/atom_feed"
doc = Nokogiri::HTML(open(url))
doc.remove_namespaces!
doc.search('feed entry').each do |item|
unless exists? :guid => item.css('id').text
create!(:name => item.css('title').text, :summary => item.css('title').text, :url => item.at_css("link")[:href], :published_at => item.css('updated').text, :guid => item.css('id').text)
item.xpath('content').each do |i|
i.css('topic').each do |topic|
id = topic.at_xpath("#topicid")
name = topic.at_xpath("#topicname")
update_attributes!(:categories=>[Category.find_or_create_by_topic_id_and_name(id, name)])
end
end
end
end
end
end
errors are:

Summary
Instead of these lines:
id = topic.at_xpath("#topicid")
name = topic.at_xpath("#topicname")
Use these instead:
id = topic['topicid']
name = topic['topicname']
Explanation
Let's look at a simple test case:
require 'nokogiri'
xml = Nokogiri::XML("<root foo='bar' />")
foo = xml.root.at_xpath('#foo')
puts foo
#=> bar
p foo
#=> #<Nokogiri::XML::Attr:0x15c1d64 name="foo" value="bar">
p foo.text
#=> "bar"
p xml.root['foo']
#=> "bar"
As you can see from the above, selecting an attribute via XPath actually gives you an Attr node, which is not the same as the string value of that attribute. (Using puts causes the to_s method of the Attr to show you only the value, but that doesn't mean that it's actually a string.)
As shown above, you need to use the text method (or value or content) on the Attr nodes to get the string value back that you really wanted:
id = topic.at_xpath("#topicid").text
name = topic.at_xpath("#topicname").text
Alternatively (and more simply) use the Element#[] method to fetch the value of an attribute off of an element directly:
id = topic['topicid']
name = topic['topicname']
