------------------------------------------------+------------------------
The interactive questioner, when it asks what to do about changes in
nullability or adding a NOT NULL field, provides multiple options. Some of
these speak ''to'' the user, some ''as'' the user.
One example of several:
{{{
You are trying to add a non-nullable field 'id' to mymodel without a
default; we can't do that (the database needs something to populate
existing rows).
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a
null value for this column)
2) Quit, and let me add a default in models.py
}}}
In option 1, Django offers the user the choice of entering the default
value. Option 2 instead is the user telling Django what to do.
Each time I read this, I'm asking myself who the "me" in option 2 is. The
most egregious case is in django.db.migrations.ask_not_null_alteration():
"[...] let ''me'' handle existing rows [...] (e.g. because ''you'' added a
RunPython [...]". In this sentence, "me" and "you" are the same.
Fix: Either reword the "provide" options to say "Let me enter a one-off
default now", or the "let me" options to the same style as the "provide"
options. I am very much in favor of the latter because I think this "me,
the user" style is terrible.
