Nwiki 1.9 installed, but not opening

Number of replies: 22
I've just installed NWiki 1.9. The installation seems to have been successful. No warnings. But whenever I go to open a wiki (new or from previous versions), I get this message:

No entries have been created for this wiki.

And that's it. Anybody know what's going on?

Hi Mark,

this variables (and errors) are from standard wiki. Did you really installed NWiki correctly? Try to copy our code into you server another time, it's possible that it were an upload error... You have to replace all files (remove all files and upload NWiki would be better wink)

DFWikiTeam, Pigui.

Progress

by Mark Penny -
Hola, Jordi.

Did as directed. Deleted all previous wiki files and folders. Extracted NWiki in site root. Now get this error (see file).

Not sure how to proceed. Need the table. Shouldn't the module create it?

Hello again.

This time I removed all wiki tables from the database, deleted all wiki folders and files from the installation, downloaded the latest version of NWiki, uploaded the zip file to the installation root, unzipped the file and navigated to Home.

Got this error (see file).

This time I deleted Wiki through the admin/modules.php, combed through all the relevant folders to make sure not a speck of anything wiki remained anywhere in the installation, downloaded, uploaded and unzipped the latest version of NWiki, and navigated to admin. I got this error (see file).

All files and folders have been installed. No tables have been created.

The site appears to be functioning normally. This was not the case after previous attempts. However, when I log out, I get this error report:

Context id 723 does not have valid path, please use build_context_path()
  • line 380 of lib/accesslib.php: call to debugging()
  • line 388 of lib/pagelib.php: call to has_capability()

It doesn't appear to have anything to do with NWiki, but one never knows.

Tried a whole new installation, extracting moodle, deleting original wiki files and folders, uploading nwiki to root and extracting, verifying that all files and folders were in place, creating and assigning whole new database, navigating to installation process, and getting this error:

wiki

wiki tables could NOT be set up successfully!

Hi Mark,

I've found an error in NWiki setup that throws this error. I going to fix it and release a new zip in few hours.

I'll need more time to fix ewiki-nwiki migration(other bugs you have reported).

Hi Mark,

I've created a new release that solves your problem above.

There was a problem in new installations of NWiki, the ones that not migrate ewiki content.

Say it isn't so

by Mark Penny -
The new release works great in the new installation, but it's not quite taking in the old one.

I removed all previous wiki files and folders, extracted the 20080401 release, and got these errors (see file).

Is this to do with the ewiki to nwiki migrations you mentioned? Seems like it shouldn't be. I've been using nwiki exclusively for the last two years.

Some rows in the tables are different. Is that the source of the problem?

Say what?

by Mark Penny -
Okay. By manually adding nwiki (wiki) to the modules table, I was able to get nwiki running for creating new wikis on the old site. The module is also able to number and list courses containing wikis created using previous versions of nwiki. But previous versions of nwiki are not displayed in the courses they are contained in. The resources link for nwikis reads modulenameplural and goes to an internal server error.

After creating a new wiki in one of the old wiki-containing courses, I get both Wikis and modulenameplural under resources and this error log in the Wikis resource view:

Notice: Undefined property: stdClass::$intro in /home/targetei/public_html/courseportal/mod/wiki/index.php on line 74

Notice: Undefined property: stdClass::$introformat in /home/targetei/public_html/courseportal/mod/wiki/index.php on line 74

The situation vaguely reminds me of an upgrade a year or two ago, but I'm fuzzy on the details and can't recall how I got the upgrade (or update) to draw in all the old nwikis (or dfwikis: I've never used ewiki).

Finally, when I open the newly created wiki, I get all this:

I get none of that on the new site (brand new site with only latest moodle and nwiki ever installed), even with developer debugging.

So what next?

The way we were

by Mark Penny -
Now I remember. Instructions here: http://moodle.org/mod/forum/discuss.php?d=53070#p242263. But a messy solution. There must be something simpler and quicker.

It involves creating a new wiki in the course, deleting the new wiki and giving its id to an old wiki.

There've been some changes made

by Mark Penny -
Couldn't bear the thought of renumbering all those wikis, so I altered the old tables to match the new ones, but left in the obsolete rows.

No change in performance.

Get the error below in one of the courses in which I used wikis extensively, one in which I have been able to create a new wiki and now have two Wiki links under Activities (not Resources, as mistakenly reported earlier)

Notice: Undefined variable: mod in /home/targetei/public_html/courseportal/course/lib.php on line 945

Notice: Trying to get property of non-object in /home/targetei/public_html/courseportal/course/lib.php on line 945

I keep thinking the module id for the wiki module must be key somehow, but I can't find it listed anywhere except the modules table. It seems like I ought to be able to make things work by returning the id to the old value (which I have, of course, forgotten).

Is lib.php looking for the module by id? If so, where do I go to change the value? Not a file, surely. Must be a table somewhere.

It's the end of the world as we know it and I feel fine

by Mark Penny -
Got it. course_modules. Problem is, when I deleted old and new wikis (several times) from admin/modules, I removed all wiki-related data from the database.

Strategy? Create dummy database. Load pre-upgrade backup. Dump relevant tables. Upload pre-upgrade relevant tables to site database. Voilà.

by Mark Penny -
It's a long, long road with many a winding turn that leads us to who knows where.

I'm in the process of manually rebuilding the lost rows of course_modules based on entries in _wiki. Much could go wrong. There may still be a few laughs in the old pony yet.

How sweet the sound

by Mark Penny -
We now have proof of concept. Of course, this will have been no secret to you old dab hands, but for me it's cause to say I've had a good day and I'll do the rest tomorrow.

The relevant relational tables are _wiki, _course_modules and _course_sections.

First, you add an entry for the wiki instance (wiki id) in _course_modules. Second, you assign the _course_module id a place in the desired section in course_sections.

I may write all this up more cogently tomorrow or the next day, after I've successfully repeated the process a few times and can be sure I haven't misconcatenated or otherwise garbled the process.

Just to repeat for my own benefit,

  1. The tables are
  • _wiki
  • _course_modules
  • _course_sections
The ids are
  • wiki
  • module
  • course
  • section
The tables and pairs are To be continued.

Installing the NWiki module was a mistake.
