Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways :

1) using many2one field in both the objects (http://tutorialopenerp.wordpress.com/2014/04/23/one2one/)

2)  using inheritance by deligation

You can easily find the first solution with little search over internet so let's start with 2nd solution.

Scenario : 

I want to create a one2one relation between two objects of openerp

hr.employee

and

hr.employee.medical.details

What I should do 

i. Add _inherits section in hr_employee class
ii. Add field medical_detail_id in hr_employee class

class hr_employee(osv.osv):
    _name = 'hr.employee'
    _inherits = {'hr.employee.medical.details': "medical_detail_id"}
    _inherit = 'hr.employee'    
    _columns = {
             'emp_code':fields.char('Employee Code', size=6, readonly=True),
             'medical_detail_id':fields.many2one('hr.employee.medical.details', 'Medical       
             Details',help="Link this employee to it's medical details", ondelete="cascade", required=True),
             ............
    }

You don't have to do anything with 'hr.employee.medical.details' object

iii. Add fields in hr_employee_view.xml file

<group col="4" string="Medical Details">            
    <field name="medical_detail_id" invisible="1" required="0" colspan="4" />
    <field name="blood_group" />
    <field name="medicine" />
    <field name="medicine_desc" />
    <field name="allergies" />
    <field name="allergies_desc" />
</group>

and you are done. It will create exactly one record each employee entry in
hr.employee.medical.details table.

Please let me know if you are facing any issue to implement it.


Thanks!!!!!!!!!!!!!!!! Enjoy Programming :)

    1. Which Odoo version you are using.....OpenERP 7.0 or Odoo 8.0? Above mentioned workaround works only in version 7.0 and doesn't support version 8.

  2. Firstly i would say this is an awesome blog for odoo. I have a custom module which imports employee, salary details that i have already in a csv file, now i want these details to refelct in hr, accounting module instead of manually creating a pay slip. I want the salary details in my file be reflected to employee payslip.
    In fact we already have a software for computing the salary, so we want to bypass the salary computation in odoo.
    Help me out
    thanks.

    1. Hi Anilraj, For custom module development best approach in Odoo is to connect your functions with already running functionality of Odoo. In your case, try to make a salary related entry from Odoo and check how the flow/control is going and then override those functions in your module. You can change salary calculation by overriding it's function. Hope you got it!

    1. Yes, you can achieve this using on_change even handler in Odoo. http://www.odoo.yenthevg.com/on_change-event-in-odoo-8/

How to draw Dynamic Line or Timeseries Chart in Java using jfreechart library?

Today we are going to write a code to draw a dynamic timeseries-cum-line chart in java.   The only difference between simple and dynamic chart is that a dynamic event is used to create a new series and update the graph. In out example we are using timer which automatically calls a funtion after every 1/4 th second and graph is updated with random data. Let's try with the code : Note : I had tried my best to provide complete documentation along with code. If at any time anyone have any doubt or question please post in comments section. DynamicLineAndTimeSeriesChart.java import java.awt.BorderLayout; import java.awt.Color; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.Timer; import javax.swing.JPanel; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.plot.XYPlot; import
