requested review from @babadie

mentioned in merge request frontend!1497 (merged)

I decided to split that work into two parts.
That first MR allows to store the data, it requires a small update of the frontend (due to serialization of the M2M) : frontend!1497 (merged).

requested review from @erwanrouchet and removed review request for @babadie
