Creating module via web-interface - odoo

Question

I followed the following steps to create a module named "x_test" :
1. Settings -->Technical --> Database Structure --> Models --> Create
Model Description : Test
Model :x_test
2. Add Fields
Name: x_sample
Field Label: sample
Field Type: boolean
3. Save
4. Click on Create a Menu
5. Select appropriate menu and click on "CREATE MENU"
6. Click on the menu provided and try to provide values for my custom module
7. When I "SAVE" my record, I am getting the following error:
Traceback (most recent call last):
File "/var/app/openerp/server/openerp/netsvc.py", line 292, in dispatch_rpc

Is there any mistake in my regards of creating a module via Web Interface

Answer 1

I had the same issue, go into the database and within the table x_test create the field you added in the model.
Now as far as I am concerned, it should create the fields for you. But I have had to create the fields manually.
