Error when importing from Vanilla


(Thomas Huulbæk Titanium) #1

So, I am trying my very best to import a ExpressionEngine forum to Discourse. I rewrote some of the Vanilla Porter to make it work with our version of ExpressionEngine (1.6.9) and got the 1.3gb CSV file. But, when finally trying to import to Discourse this happens:

	from script/import_scripts/vanilla.rb:254:in `<main>'

I guess my question is: How would I find out what line 157118 contains? I guess this is a line after the importer has done something to the original CSV? Because the original line looks fine.

CSV files are notorious for having formatting issues.

I accept that answer :smile:

This is what I ended up doing should someone else get themselves in the same situation (I doubt that!):

  1. Make copy of MySQL database.
  2. Convert database copy and tables to UTF-8 if necessary.
  3. Export to CSV via Vanilla Porter - requires some small changes in the source to support older ExpressionEngine versions.
  4. Install Vanilla and import CSV into new database.
  5. Use vanilla_mysql.rb to import from this database - either remotely or locally.

@riking: Regarding that last step I had to make minor correction because users is not defined in

   next if all_records_exist? :users, users.map {|u| u['UserID'].to_i}

Not making any PR’s because I know nothing about Ruby.


Problems after import from semi-large forum

Oops, that must have been a pasting error in my patch to skip finished chunks in the import!

I guess I was a little early in claiming success. Importing users and categories goes well but fails with Segmentation fault when starting to import topics.
