title: Table Fields are not adding in Odoo during creation of a module?
body: <p>Am a newbie in Odoo Development. I created a Module Named Mytransaction. My Module code will be like this:-</p>
  
  <pre><code> class mytrans(osv.osv):
      _name= "mytrans"
      _description= "My Transaction"
  
      _coloums = {
          'subject': fields.char("Subject",required=True),
          'date' : fields.date("Date",required=True),
          'note' : fields.text("Notes"),
          'amount' : fields.float("Amount",required=True),
          'type' : fields.selection([
              ('transport','Transport'),
              ('household','Household'),
              ('personal','Personal'),
              ], 'Type',required=True),
  
      }
  </code></pre>
  
  <p>When tried to install, its succesfully Installed...But when I activated the developer mode &amp; checked Database structure-> Model fields, its like no fields added in model is showing? How can I resolve this? How can I create fields from model?</p>
