model_serializer: support jsonify-like syntax ?

[kevinkhao]

The following PR seems very useful #177

It would be nice to have a syntax like jsonify where you can specify for example for a res.partner:

_model_fields = ["country_number:country_id"]

You would get more flexibility in the datamodel fields that you declare and how to express it into an Odoo record.

More interestingly, in base_jsonify there is a syntax to run your input through a function :

_model_fields = [ ("country_code:country_id", "_format_country_code") ]

Then the flow expressed in the current syntax would look something like:
aCountry = _format_country_code(myInput.country_code) # searches the country by code and return id
delete myInput.country_code
myInput.country_id = aCountry
to_record(myInput)

That is the basic idea, it could probably become quite flexible if more fleshed-out.

I thought of this because for example on this module https://github.com/akretion/sale-import/blob/14.0/sale_import_base/components/importer_sale_channel.py we could make it very clean with such a feature

I'm thinking also of having support for a special character inspired by https://github.com/shopinvader/pattern-import-export to use in the following way:

take for example you are calling to_record on a res.partner:

_model_fields = ["#name"]

Then the correct partner will be searched by exact "name" instead of "id", without needing to overload to_record
Another example on sale.order.line,

_model_fields = ["#order_id", "#product_id", "name"]

Then you can modify or ensure 1 sale order line with your chosen description ("name"), per order with matching a certain product.

Maybe I went too far into science fiction but it seems very expressive
