Hello
First I have to say that the new reviewboard installer (rb-site install)
assistant is GREAT. No config file to edit, each setting is explained, I
like this very much !
Now here's my problem :
I installed version 1.7.2 of reviewboard (ReviewBoard.noarch
0:1.7.2-1.fc18) on fedora 18.
I would like to migrate data from my old reviewboard 1.6.13 site to my new
environnement.
When a run rb-site upgrade to update the database, it gives an error "The
model auth.Message has been deleted [...] Your models contain changes that
Django Evolution cannot resolve automatically"
Not enough to make me give up... I run rb-site manage evolve with "--hint"
options which give me a nice "Trial evolution successful".
But It fails on the next step
> rb-site manage /path/to/rbsite -- --hint --execute
[...]
Error: Error applying evolution: (1101, "BLOB/TEXT column 'diff_base64'
can't have a default value")
See console log in attachment
my config is :
fedora 18 x64
ReviewBoard 1.7.2 (1.7.2-1.fc18)
python 2.7.3
python-django 1.4.3
python-django-evolution 0.6.7
python-djblets 0.7.8
MySQL-python 1.2.3
MySQL Community Server 5.5.29 (running on Windows)
regards,
Chris

You have requested a database evolution. This will alter tables
and data currently in the 'default' database, and may result in
IRREVERSABLE DATA LOSS. Evolutions should be *thoroughly* reviewed
prior to execution.
Are you sure you want to execute the evolutions?
