Hi,

Please check the the blog to know more about dynamic fields in Odoo.

Hey, 

you'll need to add two masters(new models), one will correspond to the manufacturer and the other to the manufacturer's model. In the manufacturer's model master, there will be a field corresponding to the manufacture. 

Now after adding the masters, you'll add two fields in the product view. One for "manufacturer" and another for "model". When the user selects the "manufacturer", trigger a method that will apply a domain for the "model" dropdown. It's called applying dynamic domain. 

This should work.

Thanks

Thank you for your answer, but I still have no idea how to make this fields  in products.

I think that blog for professionals...

What is the file wizard.py? Where should I create or edit it? or is it necessary to create a new model for this? Where should I place the get_possible_field_types method? In my new module in models.py? The same with onchange_field_type method...
I can't find any tutorials for beginners, there is only information for professionals.  For a example for django, I can find a huge amount of information and tutorial videos for beginners, and absolutely nothing for odoo.
