Do we actually have any case where missing value is acceptable ? Also consider that NULL returns different results than an empty string in queries. Will this affect smth? Are we sure we should prefer NULL?
@virtualfeline This is the default behaviour of Rails, if by missing value you mean empty string. I bet 99% of text columns in our database are empty if no value has been provided at the application level. I don't see production data so I cannot say how many of them are empty.

Exactly! I am sure I want to see NULL
when the data is missing or unknown, since this is the point of NULL
. But is it worth the effort or not, is the topic of this ticket.
If we leave it as is:
Example: #746 introduced contact reuse, so if one contact has fax value of "", and another of NULL
, they will not be considered identical, and therefore will not be reused.
@vohmar FYI
In Rails when saving a model from a form and values are not provided by the user, an empty string is recorded to the database instead of a NULL (mixing blanks and NULLs can become confusing).
