Meet the Sulley

Sulley, from inside and his broken vertebral column


Sulley’s sad. He can’t bounce any more. Nor to wiggle his tail.
The toy for $10 supposed to last more than a couple of days, i suppose.

Thank You Disney, for moving your engineering department closer to the manufacturer.

Unknown column ‘tplname’ in ‘order clause’

Found an error when deploying GLPI plugin “Generic Objects Management” v 1.1.3 from

I could add and modify object types, but was unable to add objects. Clicking “Add” button did nothing.


Switched GLPI to debug mode and found “SELECT * FROM `glpi_plugin_genericobject_…` WHERE is_template = ‘1’ AND FK_entities=’0′ ORDER BY tplname 0.001 Unknown column ‘tplname’ in ‘order clause’ ” near the bottom.
Of course, the was no ‘tplname’ field in the DB.

A quick search in the sourse revealed:
the apropriate database is created when object’s type is created;
the function “plugin_genericobject_addTable($name)” resides in “inc/plugin_genericobject.objecttype.function.php”

$diff -u plugin_genericobject.objecttype.function.php.orig plugin_genericobject.objecttype.function.php

‘tplname’ field should be altered in “plugin_genericobject_enableTemplateManagement” function, but for some reason it isn’t.
That’s all.

The site was down. Why?

Actually, it wasn’t down. Just the information was not displayed.

The reason is simple – after a prolonged migration to Atom MoBo, data crash in one of physical discs, loss of some MySQL databases, a new WordPress installation was missing the theme i’ve used. So, quick edit in ‘options’ table, replacing ‘option_name’ ‘template’ and ‘stylesheet’ with walue ‘default’ made the trick.
As you see, the blog is up and running again.

It happens

History is just what happens to us.

I hope this blog will be a cosy place to find some totally useless crap.
