Hi,

the following class

class Account
include SimplyStored::Couch
property :name
property :type
validates_inclusion_of :type, :in => ["a","b"]
end

leads to following error :
undefined method `add_validations' for Account:Class

the following works fine:
validates_presence_of :type

my configuration: rails 3.0.0, ruby 1.8.7, gem 1.3.7, simply_stored 0.3.8, validatable 1.6.7

To reproduce:
class Department
include SimplyStored::Couch
has_and_belongs_to_many :losses, :storing_keys => true, :class_name => 'Loss'
end

class Loss
include SimplyStored::Couch
has_and_belongs_to_many :departments, :storing_keys => true, :class_name => 'Department'
end

when calling, a_department.losses we get an uninizialized constant error, that it can't find 'Los'

This occurs when in get_class_from_name we pass in the class name of 'Loss' and when calling classify on 'Loss' it shrinks it to 'Los'.

hi...this is a pretty noob question....when I use find_by_email I get:

Warning: Defining view User#by_email with keys "email" at call time, please add it to the class body...
I don't know what must I do and use a method in call time result very slow and I'm used to datamapper style finder; there are any way for find whitout dynamic finder; I've tried it:

user=User.first(:name => "gaga") nice style datamapper
or

user=User.find(:first, :condition =>{:name => "gaga"}) ugly old rails version

but any work

thanks

Forgive me if this is stated some place else in the docs. I looked and couldn't find any information regarding version compatibility.

Ruby 1.9.2-p180
Ubuntu 10.04

The same thing happens when irb when attempting "require 'simply_stored''

I found this reference: https://gist.github.com/137401 (last entry) which indicates the above is indeed unsupported in Ruby 1.9. There is also this post: http://www.ruby-forum.com/topic/136408

I ran into this error when I was doing an myarray.include?(:some_symbol)

myarray holds some SimplyStored Documents ... when comparing of those it raises an

undefined method `_id' for :mySymbol:Symbol
/usr/lib/ruby/gems/1.8/gems/simply_stored-0.3.6/lib/simply_stored/instance_methods.rb:11:in `=='

this comes as the equals method (==) does not check whether other is an simply stored object. So any object is asked for its _id-method which of course is not available for objects of foreign classes.

So instead of

def ==(other)
    other._id == _id && other._rev == _rev
end

just do

def ==(other)
    other.kind_of?(SimplyStored::Couch) && other._id == _id && other._rev == _rev
end

and the problem is solved.

This was fixed in the 0.6.0 of couch_potato to make it compatible with rails 3.1, since simply_stored is using 0.5.7 the issue is there.

See for reference:

Dears, i was trying SimplyStored with CouchDB today with rails master and simply_stored master
after configure and running i got the following :

firstly, when calling the index method of the model "localhost:3000/posts" .. its shows RestClient::RequestTimeout (Request Time Out).

when trying to create a model which have Date property as :type => Date or :type => :date
i got the following undefined method `start_date(1i)='

Is there any way to have more then on association point to another simply stored item?

IE can we do the following:

class Document
  include SimplyStored::Couch

  belongs_to :creator, :classname => "User"
  belongs_to :updater, :classname => "User"

end

CouchDB - Custom Associations

class Document
  include SimplyStored::Couch
  belongs_to :creator, :class_name => "User"
  belongs_to :updater, :class_name => "User"
end


d = Document.new
d.creator = User.first

leads to following error :
ArgumentError: wrong number of arguments (2 for 1) in `belongs_to'

since .11, couchdb supports the notion of linked documents (emitting _id). it would be beneficial if the default views would leverage this to fetch associated documents

Taking the example from the fixtures file in the simply_stored tests for User and Document.

When doing a_user.add_doc a_document, we get a 'NameError: uninitialized constant Doc'

Because in https://github.com/peritor/simply_stored/blob/master/lib/simply_stored/couch/has_many.rb#L61 we call simply_stored/class_methods_base.rb:5:in `get_class_from_name'" and then we are passing in 'docs' instead of the custom specified :class_name of Document.

So when defining the setter for has_many, it thinks that the class name is Doc instead of Document.

Here's a console output of this issue: https://gist.github.com/1304852

I have found that in simply_stored/lib/simply_stored/couch/finders.rb there is a :first method implemented, so I can fetch the first record of that type. Working.

But I am missing a :last method allowing me, to get the last record ...

should be something like

def last(*args)
  find(:last, *args)
end

as the first query is made via

CouchPotato.database.view(all_documents(:limit => 1)).first

it seems that a performant approach has to look different for last as for first as we cannot use that :limit => 1 here

when I try to persist an instance of the entity class defined inside the module, I'm getting following exception:

...

here is my entity class:

module ThShop
  class Product
    include SimplyStored::Couch

    belongs_to :supplier
  end
end 

apparently, the problem is in the slash character inserted into the method name.

I'm using simply_stored 0.5.3 with Ruby 1.9.2-p180 on Windows.

The generated find_by view doesn't know that my field is a Fixnum. Is that possible with simply_stored?

class Product 
  include SimplyStored::Couch
  property :quantity, :type => Fixnum, :default => 0
  validates_numericality_of :quantity, :allow_nil => true
end

Product.find_by_quantity(123) # => nil
Product.find_by_quantity("123") # => #<Product (etc.) quantity: 123 >

I'm new to Rails 3 and simply_stored. When I try to create a Model class (such as User) with the line 'include SimplyStored::Couch', I get an error:

class:User': uninitialized constant User::SimplyStored (NameError)".

In the 'Usage' section of your website, it says to include the lines:

require 'simply_stored/couch'
CouchPotato::Config.database_name = 'couchdb_test'

But I'm not sure where these should go. I've tried putting them in a file 'config/couchdb.rb', and in the Gemfile, but it doesn't make any difference.

I'm using Rails 3.0.0.rc2, simply_stored 0.3.9, couch_potato 0.4.0, couchrest 1.0.1, and CouchDB 1.0.1, running on Windows XP SP3.

Thanks for your help.

I have a form with a text field, for which I'd like to validate the contents as numerical.

Unfortunately, properties defined with a type are typecast on assignment (this is couch_potato behavoir, I believe). So if I assign a string to a property of type Fixnum, the value is typecast (meaninglessly) to 0.

class Product 
  include SimplyStored::Couch
  include Validatable
  property :quantity, :type => Fixnum
  validates_numericality_of :quantity
end

p= Product.new(:quantity => "not a number")
p.valid? # => true
p.quantity # => 0

Has anyone else come across this? Any advice on how to handle this? It seems like it might be reasonable behavior from the perspective of couch_potato, which has something like 'statically typed' attributes. But it certainly doesn't make sense in the context of validations.

Model.first or any other db call returns an hash.
res = Model.first
res.name wont work.
But documentation says, we can make res.name call.
And also can I know how to update a record.

this is more of a usability thing. i accidentally defined a property and a belongs_to with the same name. the resulting error message was 'undefined method `options' for #CouchPotato::Persistence::SimpleProperty:0x17e581f9'

maybe this makes sense to seasoned ruby-ists, but it threw me off for a bit.
