Using Existing Database - Model has no column

I'm developing a new rails project using an existing SQL SERVER 2008 database.

rails 4.1.2 tiny_tds activerecord-sqlserver-adapater 4.1.2

my model is

class IpProject < ActiveRecord::Base   self.table_name = 'IP_Projects'   self.primary_key = "ProjectID" end

I know I can connect to the database because I get a result when I try to get count of all data.

IpProject.count

but I can't retrieve data as it has no column

IpProject.columns returns

I get results using ActiveRecords ActiveRecord::Base.connection.exec_query("SELECT * FROM ip_projects")

I also get result using tiny_tds client.execute("SELECT * FROM ip_projects")

Also, getting result using the model this way IpProject.connection.exec_query("SELECT * FROM ip_projects").first

but using the model IpProject.first returns #<IpProject:0xab01c98> which has no columns or data

Am I missing something here?
