How do you import them from csv?

I'm using MySql and I use this command to import from csv:

LOAD DATA LOCAL INFILE "$(PathToCSVFile.csv)" INTO TABLE chiliproject.issues FIELDS TERMINATED BY "," ENCLOSED BY '"' LINES TERMINATED BY "\r\n";

Sorry for the late response :-(

The calculation of the done ratio for parent issues is done in ChiliProject at issue update time, so if you're writing directly to the database, you'll have to update those yourself too (and every other attribute that might be related to the ones you're updating…). You'll notice you probably don't have the journals (in the activity view) for updates you do via this method.

The "better" way to do this would be to update the issues in ruby (via the script/runner script which gives you a "ChiliProject environment in a ruby script", i.e. you can then program something like issue = Issue.find(123); issue.some_attribute = "new_value"; issue.save which should trigger everything "else" ChiliProject does around the update) or via the web API (which I realize might not be complete enough for your use-case, do tell us if that's the case).
