Redmine

I've the same problem...

I will erase the plugin directory directly, but when the plugin has a DB modification, I'm afraid to just delete the folder...

I've checked the down method in db migration, and I will also delete the created tables, and delete the colums added...

Any better solution?

I'm sure there is a RAKE script solution...

Some infos here : http://dev.rubyonrails.org/ticket/6423
There should be a way with rake, rake db:migrate:plugins PLUGIN=[your plugin name] VERSION=0, but it doesn't seem to work for me, don't know why.
I'm also very interested in a clean solution :-)

Hum, I read it to the end, and it hasn't been integrated...
Maybe redmine rake task should be updated ?

There's an Engines task to do this but I didn't managed to make it work ; if you want to investigate, it's located in vendor/plugins/engines/tasks/engines.rake. The syntax is particular since it accepts parameters. It may be run like this : rake db:migrate:plugin NAME=my_plugin VERSION=desired_version, or maybe rake db:migrate:plugin[name,version]. Anyway, rake complains it doesn't know how to build the task, or Engines is not initialized...

I think Redmine developpers wouldn't modify Engines tasks, so I created my own task, it works fine, and I'll submit a patch today.

How can I apply down method ?

Any better solution?

I didn't find better ( db:migrate_plugins PLUGIN=xxx VERSION=0 doesn't work)

I'm sure there is a RAKE script solution...

Did you find one ?

Thank you

UP

Is there a good solution for this ?

See #2265 but still not much progress I am afraid

Hi. What about doing:

ruby /script/plugin remove {name_of_the_plugin}. {name_of_the_plugin} must match the plugin name
in /vendor/plugins.

It worked for me!

After running:

ruby script/plugin remove ezfaq_plugin

I get:

svn: '/var/data/redmine/vendor/plugins' is not a working copy

What does this command have to do with svn??

I got same error, need help.
official 0.8.4 release under ubuntu9.04

Try the instructions at this blog:

http://nubyonrails.com/articles/the-complete-guide-to-rails-plugins-part-i

Just to quote a part from the blog above:

"To uninstall a plugin, you can:
Delete the specific folder for the plugin
Remove it with svn delete
Unlink it with svn propdel svn:externals vendor/plugins/ "

Hope this helps

None of these answers address undoing any schema changes that a plugin has done or removing its data. It looks like uninstall hooks will be available when Redmine uses a newer version of rails.

Did we ever get any successful results on how to uninstall Redmine plugins? Yesterday I tried upgrading to the current development version and everything was going fine until I tried to access the settings tab on each of my projects and received an Internal Error, I'll have to guess this is caused by one of the plugins that I've installed not being compatible and like Ethan said none of the above address the removal of a plugin if there has been any schema changes.

If there isn't any current solution, I might have to look through the database and do a manual removal not something I'm looking forward to.

Any progress with this problem?

Hi hope this patch helps - does for me ;)
Usage as mentioned before:
rake db:migrate:plugins PLUGIN=[your plugin name] VERSION=0

I would guess, that there is a more decent way of doing this, but this one integrates pretty well.

In current trunk Engines has been updated, and you can do something like :
rake db:migrate:plugin NAME=plugin_name VERSION=0
It works for me, maybe you can try this and compare with your patch ? (didn't look at it sorry, since I'm on my phone....)

well, that works, so my patch gets quite useless (except for people using an old Engines)

The description to my patch, however, was wrong it would be (note '_' not ':' in migrate_plugins, and it's still plural):
rake db:migrate_plugins PLUGIN=[your plugin name] VERSION=0

anyways, while migrating a single plugin works, rake db:migrate:plugins does not (undefined method `migration_directory')

Isn't it possible to create a remove plugin button in Redmine. Would be a lot easier.

It's nearly impossible, mostly because you need a restart of your redmine instance each time you add or remove a plugin.

And even if you have very simple plugins with limited modifications of redmine core, you can have surprises depending on how you host it : with passenger or mongrel_cluster, you have different instances of the application runnning together, and I think it's a good idea to keep them on the same level / environment.

See also #4394.

The above mentioned procedure does not work for me.

$ rake db:migrate:plugin NAME=redmine_theme_changer VERSION=0
(in /opt/redmine-1.1.1)
Migrating redmine_theme_changer to version 0 ...
rake aborted!
SQLite3::SQLException: no such table: schema_migrations: SELECT version FROM schema_migrations

If you're trying that on a production site, you might need to prepend the command with RAILS_ENV=production.

So I wrote a short script (name: uninst_redmineplugin.sh ) for redmine installed on a bitnami image (otherwise you just have to amend some paths and replace the restart command for redmine):

#!/bin/sh
rake db:migrate_plugins PLUGIN=$* VERSION=0 RAILS_ENV=production
mkdir -p [redmine_root_dir]/vendor/plugins.inactive
mv [redmine_root_dir]/vendor/plugins/$* [redmine_root_dir]/vendor/plugins.inactive/

/opt/bitmine/ctlscript.sh restart

After creating the scriptfile uninst_redmineplugin.sh you have to make it executable with

1. chmod 755 uninst_redmineplugin.sh

Then you may start the script with the name of the plugin as parameter:

1. ./uninst_redmineplugin.sh NAME_OF_PLUGIN

With this script I was able to uninstall some plugins from redmine.

I was a bit too fast.
The last line in the script needs to be corrected:
If you use indeed bitnami please
replace 'bitmine' by 'bitnami'.
If you don't use an bitnami image you have to use a different command anyway.

What is the correct way to uninstall plugins?

Redmine 2.2.3
Rails 3.2.12
Centos 6.3

I tried:

rake db:migrate:plugins PLUGIN=redmine_charts VERSION=0

but I got an error, there was no rake task called db:migrate:plugins.

So I tried:

rake redmine:plugins:migrate PLUGIN=redmine_charts VERSION=0

and I got:

rake aborted!
uninitialized constant RAILS_DEFAULT_LOGGER
