Successful, No-Nonsense Installation of NWiki and Conversion of DFWiki

Here's how I did it (in a copy of my production installation with a copy of the production database).

  1. Exported DFWiki tables.
  2. Deleted DFWiki and Wiki Book (aka Itinerary) in Administration/Configuration/Modules, and DFWiki blocks in Administration/Configuration/Blocks.
  3. Deleted DFWiki folders and files (in folders mod [incl. Itinerary], blocks, course, lang).
  4. Installed NWiki.
  5. Dropped mdl_wiki, mdl_wiki_pages, mdl_wiki_synonymous.
  6. Imported DFWiki tables.
  7. Renamed mdl_dfwiki to mdl_wiki, mdl_dfwiki_pages to mdl_wiki_pages, mdl_dfwiki_synonymous to mdl_wiki_synonymous.
  8. Added Wiki to course section.
  9. Deleted said Wiki in mdl_wiki.
  10. Changed id  of desired DFWiki to id of just deleted Wiki.
  
Works like a charm. Just remember to back up whatever tables you play with. In fact, it's best to back up the whole database, just in case.

Funny. I still get that dratted blank admin/index.php page. I thought I'd licked that.

Ah. It was that old feud between NWiki and DFWiki again. Somehow DFWiki installed itself again, though without tables. Perhaps I had forgotten to delete the folders. After deleting the dfwiki folders in mod and blocks, I get a nice admin/index.php page.

Well, mostly nice. Now I get the regular menu plus, because I've enabled debugging, these notices

They all seem to be related to this bit of code:

// dfwiki-block || course-block
    $dir="";   

I'm no programmer, but I can see a value is missing. What value should it be?

And when I open the wiki, I get these notices:

Notice: Undefined property: stdClass::$evaluation in /home/targetei/public_html/testcourseportal/mod/wiki/locallib.php on line 2278

Notice: Undefined property: stdClass::$notetype in /home/targetei/public_html/testcourseportal/mod/wiki/locallib.php on line 2292

Notice: Undefined index: editor in /home/targetei/public_html/testcourseportal/mod/wiki/locallib.php on line 248

Everything seems to be functioning, but one does wonder what's going on behind the scenes and when the scenery is going to come tilting down on the action.

When I edit a page I get

Notice: Undefined property: stdClass::$evaluation in /home/targetei/public_html/testcourseportal/mod/wiki/locallib.php on line 2278

Notice: Undefined index: editor in /home/targetei/public_html/testcourseportal/mod/wiki/locallib.php on line 248

When I view a discussion I get

When I edit a discussion I get the same as when I view.

When I save an edit of a discussion, I get

Re: Successful, No-Nonsense Installation of NWiki and Conversion of DFWiki

by Mark Penny -
Had a great deal of trouble making the procedure work in my production installation. As I continued to suspect, despite the mysterious nature of the glitch, it all came down to one simple digit in one field of one record of one table of the database: the instance of the module in the section of the course in mdl_course_modules. I must have lucked out the first and second times--as I recall, anyway. I certainly don't remember having gone into that table to make any changes.

The instance is the id of the record in mdl_wiki. All the associated pages will have this same number in the field dfwiki. This number must be entered in the field instance of course module in mdl_course_modules.

Yes, where is that reply?

Meanwhile, if nwiki is working, I wouldn't worry about those notices. I get them, too (when degugging is on), but nwiki is running fine for me. They differ from warnings. Nothing bad is happening and you're not missing out on anything good (as far as I know).

I'm afraid your difficulties are somewhat over my head at this point. Maybe Ludo can help. You might try emailing him.

I hate to ask, but are you sure the wiki isn't working at all? You mean you simply cannot create a new wiki? I ask because I get notices about errors almost anytime I do anything in Moodle, but almost everything is working fine.

Unfortunatly, the error I quoted is what I get when I try to create a wiki or go to that wiki.

Re: Successful, No-Nonsense Installation of NWiki and Conversion of DFWiki

HI Rabbi,
I'm sorry fro my abcense I was since sunday attending to the MoodleMoot spain in tarrragona.

I need the following information:
Server: operating system, database and web server (ex ubuntu, apache, mysql)
Moodle version (1.6.2 rev xxx)
Nwiki version (we posted one new last week.
Does your server come from scratch or is a 1.5.2 migration ??
Do you have any wiki activity running that you wish to keep?
Do you have other non standard module or plug in?

In adition to Mark's suggestions( Thanks Mark ), and in teh case scenariuo that you have no data to loose, I should consider the following :
delete the wiki module in the admin/modules page
remove the folder mod/wiki
remove all the tables in database with "wiki" on its name
try start all over again.

I've tested for the moodlemoot several configuration sof moodle 1.6.2 with success. Including the XAMP moodle distribution on windows, and it works pailessly.
Let's try it, I wish to get your installation up and running!
Ludo

Thank you Mark.

1. Server: unix

2. database apache &  mysql

3. Moodle version: 1.6.2

4. Nwiki version (we posted one new last week.) Where exactly is the newsest version??

5. Server came from scratch

6. No wiki activity

Other non standard modules: wikibook

We tried what you said and we even reinstalled moodle but the wiki is still giving us this problem:

When dfwiki is installed in the dfwiki directory it works but when we try and install it the wiki directory our site turns into a blank screen (We seem to be having some problems with blank screens even when we navigate)

Re: Successful, No-Nonsense Installation of NWiki and Conversion of DFWiki

by Mark Penny -
I really feel for you. I really, really do.

In situations like this, I try a complete deletion and reinstall.

You might consider
  1. exporting (copying, backing up) your entire database,
  2. exporting all your wiki, dfwiki and nwiki tables (I don't know what you've got in your database),
  3. creating a subdomain, database and database user for a test moodle,
  4. installing 1.6.2 to the test moodle,
  5. installing the latest version of nwiki to the test moodle,
  6. trying nwiki out in the test moodle,
  7. getting nwiki to work in the test moodle,
  8. replacing the nwiki tables in the test moodle database with the nwiki, dfwiki or wiki tables from your production moodle database,
  9. creating a clone of a production moodle wiki, dfwiki or nwiki in the test moodle,
  10. tweaking numbers in the tables to get the clone to draw on the original data,
  11. cloning and data-populating, in the test moodle, all your production moodle wikis, dfwikis and nwikis,
  12. exporting all the nwiki tables in the test moodle database
  13. dropping (deleting) all the wiki, dfwiki and nwiki tables in the production moodle database (you've got copies from the exports in steps 1 and 2, so you can always put them back if you need to),
  14. importing the nwiki tables from the test moodle database,
  15. deleting or renaming all the wiki, dfwiki and nwiki folders and files in the production moodle,
  16. and copying all your nwiki files from the test moodle the production moodle.
There are variations on the general programme and on particular steps. I don't know how advanced your database lore is, so I've given you the steps that I would have followed when I started playing around under the hood. I suppose if I were really advanced, I 'd be able to give you a much shorter and simpler procedure.

Actually, I've given you a neophyte approach to two separate activities: successfully installing nwiki and successfully running dfwiki-generated wikis through nwiki. I understand you are switching to nwiki from wiki (Erfurt Wiki). That I can't help you with, never having done it. I'm newer to Moodle than you are, I suspect.

I find that when things don't work for me after I think I've followed all the steps exactly, it's because I've left something out or done something wrong. Sometimes there really are bugs, but very often the only bugs are in my belfry.
