The Lounge What is on Your Mind? Under Consideration: Migrate the Forums to Discourse
# 15  
Status Update:

Code:
   262021 / 651396 ( 40.2%)  [590 items/min]

Reported bug in the vbulletin.rb script at meta discourse but will not post any more bugs regarding vB3.8.X migration to discourse over there.

Back to working on the migration.

Also, I am also considering to keep both forums up and running and leave this one at www.unix.com and keep the discourse.unix.com forum separate. Need to think about this and how it might hurt SEO for one site or the other in the future..
# 16  
Note:

I compared the "forums which ported to categories" against "forums which did not port to discourse categories" and the forums "which did not port" all had a parentid of -1,

So, I think this can be fixed by altering the "dumped DB" and changing all forum parentid to -1.

I will do this as a part of "round 2" after this migration test is done.

OK... looking at this:

discourse/vbulletin.rb at master . discourse/discourse . GitHub

The bug is in this block:

Code:
 def import_categories
    puts "", "importing top level categories..."

    categories = mysql_query("SELECT forumid, title, description, displayorder, parentid FROM #{TABLE_PREFIX}forum ORDER BY forumid").to_a

    top_level_categories = categories.select { |c| c["parentid"] > -1 }

    create_categories(top_level_categories) do |category|
      {
        id: category["forumid"],
        name: @htmlentities.decode(category["title"]).strip,
        position: category["displayorder"],
        description: @htmlentities.decode(category["description"]).strip
      }
    end

    puts "", "importing children categories..."

    children_categories = categories.select { |c| c["parentid"] != -1 }
    top_level_category_ids = Set.new(top_level_categories.map { |c| c["forumid"] })

    # cut down the tree to only 2 levels of categories
    children_categories.each do |cc|
      while !top_level_category_ids.include?(cc["parentid"])
        cc["parentid"] = categories.detect { |c| c["forumid"] == cc["parentid"] }["parentid"]
      end
    end

    create_categories(children_categories) do |category|
      {
        id: category["forumid"],
        name: @htmlentities.decode(category["title"]).strip,
        position: category["displayorder"],
        description: @htmlentities.decode(category["description"]).strip,
        parent_category_id: category_id_from_imported_category_id(category["parentid"])
      }
    end
  end

On work around I have which am looking at is to just rerun this script with a small change, making all categories top level for now:

Code:
 top_level_categories = categories.select { |c| c["parentid"]  > -2}.  # make all forums top-level categories

    create_categories(top_level_categories) do |category|
      {
        id: category["forumid"],
        name: @htmlentities.decode(category["title"]).strip,
        position: category["displayorder"],
        description: @htmlentities.decode(category["description"]).strip
      }
    end

and "false out"

Code:
if false
children_categories = categories.select { |c| c["parentid"] != -1 }
    top_level_category_ids = Set.new(top_level_categories.map { |c| c["forumid"] })

    # cut down the tree to only 2 levels of categories
    children_categories.each do |cc|
      while !top_level_category_ids.include?(cc["parentid"])
        cc["parentid"] = categories.detect { |c| c["forumid"] == cc["parentid"] }["parentid"]
      end
    end

    create_categories(children_categories) do |category|
      {
        id: category["forumid"],
        name: @htmlentities.decode(category["title"]).strip,
        position: category["displayorder"],
        description: @htmlentities.decode(category["description"]).strip,
        parent_category_id: category_id_from_imported_category_id(category["parentid"])
      }
    end
end

This might work better.

I'm fairly confident now that, after the first "test migration" if over (in a day or so) , I can make this port work nicely with some simple modifications to the Ruby import script in the area of:

Code:
Forums to Categories
Custom BB Code Tags

Now, waiting for all the posts / replies to import and then the attachments.

I think there is a potential problem with attachment, so after it is all "done" in this test round, I will have info info to make more adjustments in the Ruby migration script.

Plus, I get to learn a bit of "Ruby" along the way. Smilie

The only "cautionary" comment I have so far is that of the two people on the "discourse side of the house" I have interacted with so far, both "had their hands out" looking to make money off this migration. One guy was a hired gun "migration expert" who wanted money to help me and the other person was in the discourse forums, the other was a discourse server provider.

This jives with some of the posts I have read which stated that discourse was free and the developers and other make a lot of money on associated hosting and services.

That's a lot different than the Node-RED community I have been interacting with where both Node-RED is free and the community is a robust, friendly group of "makers" all showing off their skills and talents and sometimes over-projecting their skills to attract attention; but they are truly helpful to all, especially noobs.

Discourse, on the other hand, seems to want to steer noobs to paid services.

That is not a big negative; as everyone has a right to make a living; and I heard the owners of Discourse make a fortune.

Quick Q...
do I need a new account for the discourse "side of the house"?
Tried my creds from the main site, getting "Incorrect username, email or password"
Or it's not been "enabled/migrated" yet?
