I'm preparing a csv file to be imported into RavenDb, and have a column named Raven-Entity-Name to specify into which collection the documents have to be imported.
This data will be used by an ASP.NET MVC app, and so that RavenDb's default identity part separator (/) doesn't wreck havoc with my routes, I define a custom one on my app's start-up:
DocumentStore.Conventions.IdentityPartsSeparator = "-";
The csv import actually generates id's using the default separator, is there a way I can specify a custom IdentityPartsSeparator when importing a csv file or is manually generating the id's on the csv file the only option?
No, there isn't. You need to load the csv file using your code to control that.
