I have a function that process some data and the result od this need save in a database.
All process of data work fine, but the problem is when i want save the data in a database, not have any error in process.

When i use "ids" in create(), as self.pool.get('hr.attendance').create(cr,uid,ids,datas)  this give me an error(see below)

What I do wrong?

This is my function: 

    def import_time(self, cr, uid, ids, context=None):
        def see_time(x1, x2, x3, z1):
            x21 = str(timedelta(hours=x2))
            x31 = str(timedelta(hours=x3))
            res1 = (datetime.strptime(x1, '%H:%M:%S') - timedelta(hours=3)) - datetime.strptime(x21, '%H:%M:%S')
            res2 = (datetime.strptime(x1, '%H:%M:%S') - timedelta(hours=3)) - datetime.strptime(x31, '%H:%M:%S')
            zz = 'action'
            if (z1%2)==0: 
                    zz = 'sign_in'
            else:
                zz = 'sign_out'
            return zz

        for lines in self.browse(cr, uid, ids):
            attendance_obj = self.pool.get('hr.attendance')
            mess = []
            cr.execute('SELECT user_time, hr_employee.id '\
                'FROM hr_py_import_time, hr_employee '\
                'WHERE user_id=id_inter')
            temp = cr.fetchall()
            cr.execute('SELECT date_start, date_end '\
                'FROM hr_employee, hr_py_turno '\
                'WHERE hr_py_turno.id=id_turn')
            turn = cr.fetchall()
            contar = -1
            for x in temp:
                te = x[0]
                us = x[1]
                te1 = te.split(' ')[1]
                contar+=1
                for y in turn:
                    res = see_time(te1, y[0], y[1], contar)
                    datas = {'employee_id':us,'name':te,'action':res,}
                    crea = self.pool.get('hr.attendance').create(cr,uid,datas)
                    attendance_obj.write(cr,uid,crea,datas,context=context)

                     #this not work too, not save any data

                    #cr.execute('''INSERT INTO hr_attendance (employee_id, name, action) VALUES( %s, %s, %s)''',(us, te, res,))

          #this is only for see the results of process

            raise osv.except_osv(_('Atención!'),_(type(res)))

Now this is my view: 

<record model="ir.ui.view" id="hr_py_import_time_menu_form">
            <field name="name">hr_py_import_time_menu_form_view</field>
            <field name="model">hr.py.import.menu</field>
            <field name="arch" type="xml">
                <form string="Importar">
                    <sheet>
                        <label for="name" string="Periodo" class="oe_inline"/>
                        <field name="name" class="oe_inline"/>
                        <button colspan="1" name="import_time" string="Importar Horas" type="object" class="oe_highlight"/>
                        <group>
                            <field name="time_s"/>
                        </group>
                    </sheet>
                </form>
            </field>
        </record>

        <record model="ir.ui.view" id="hr_py_import_time_menu_tree">
            <field name="name">hr_py_import_time_menu_tree_view</field>
            <field name="model">hr.py.import.menu</field>
            <field name="arch" type="xml">
                <tree string="Importar">
                    <field name="name"/>
                </tree>
            </field>
        </record>

The error:
