inheritance - is it possible to add new methods to a inherited module in openerp -


I have a legacy module for "purchase" if I add a new method to buy.py, I am able to use in my opinion (form). However, if I add it to the inherited module I am not able to use it in form view.

Is there a way to add my new method to the inherited module?

In advance thanks

Actually what you need to do for your code To work in the module found in: 

  _inherit = 'purchase.order'

and then call your function with the updated XML View. Examples for example: 

  class account_asset_asset (osv.osv): _inherit = 'account.asset.asset' def _check_value (self, cr, uid, id, context = none) : For the property in self. Browse (CR, UID, ID, Reference = Reference): If asset.purchase_value & lt; 0.0: return incorrect return correct _constraints = [(_check_value, 'property value must be greater than 0!', ['Purchase_value']),]

will check whether the asset is 0 More is not wrong in return, so that users can save their records. What's more, you can easily override the function used in inherited models so that it works the way you work for you.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
