Hi
You can add a controller to do that

1.In website form add the action and method as post-

action="/create/product" method="POST" 

2.Add a controller
@http.route('/create/product', type="http", auth="public", website=True) 
 def create_product(self, **kw): 
request.env['product.patient'].sudo().create(kw)


Make sure that the fields in the website form is same as product,otherwise add them as a dict instead of kw

Hello, 

it is very simple with the help of Studio. You can go to the inventory => Products. Then click on the studio icon and go the website tab. Then click on the form and prepare the form in the website.
