Hi Camilo!

thanks for your feedback. Could you tell me what redmine version are you using?

Regards!

[camilonova]

Redmine 1.2.1.stable (PostgreSQL)

Thanks

[zuinqstudio]

I was able to reproduce the exception by deleting the facts table registers. Could you check if 'chuck_norris_facts' table contains any row? Also, I've just commited a fix to avoid the exception when no fact is found.

[camilonova]

Thanks, that solves the problem, how can i get the facts?

[zuinqstudio]

If you followed the installation notes on README.rdoc, the database migration step should have created the table chuck_norris_facts for you. Please, verify this table exists on your redmine database, and that it contains one or more row.

[camilonova]

Yes i have done all the steps, this is the output of the command:

Migrating redmine_chuck_norris...
==  CreateChuckNorrisFacts: migrating =========================================
-- create_table(:chuck_norris_facts)
NOTICE:  CREATE TABLE will create implicit sequence "chuck_norris_facts_id_seq" for serial column "chuck_norris_facts.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "chuck_norris_facts_pkey" for table "chuck_norris_facts"

   -> 0.0015s
==  TranslateChuckNorrisFacts: migrated (1.9454s) =============================

There is data in the table chuck_norris_facts but it doesnt show in the page, and no errors are given in the log

[zuinqstudio]

I still can't reproduce the issue. Please, check also this:

• Verify that the facts table has rows in english and spanish (column lang equals to 'en' and 'es')
• Try to force a fact reloading. Once you enter on the project overview, click the 'Next fact' link.

I'll keep trying to reproduce the problem in my own redmine, and keep you informed.

Regards!

[camilonova]

Thanks, i just look at the table and they has data, but the column lang was empty, so you should give a look at the content loading when setting the language in every row.

redmine=> select * from chuck_norris_facts limit 1;
 id |                description                 | lang 
----+--------------------------------------------+------
  1 | Guns don't kill people, Chuck Norris does. | 
(1 row)

I have done an sql update for all rows in the table and now it works ok, what i do was:

redmine=> update chuck_norris_facts set lang = 'en';
UPDATE 7354

and now i have:

redmine=> select * from chuck_norris_facts where id = 1;
 id |                description                 | lang 
----+--------------------------------------------+------
  1 | Guns don't kill people, Chuck Norris does. | en
(1 row)

[byteborg]

Got similar problem on Postgres. Spanish quotes are loaded with lang set to 'es' and a lot of spaces. English quotes are loaded with a lot of spaces as lang key.

[zuinqstudio]

Thanks for your feedback byteborg. It seems an encoding issue, could you tell me what OS are you using?

Regards!

[zuinqstudio]

Just installed postgres and I'm getting the same issue indeed. I'll keep you informed as soon as I fix it. Thanks again for your interest and sorry for the inconveniences.

Regards!

[zuinqstudio]

I've uploaded a new version that fixes the problem. I'd appreciate it if you could uninstall the plugin and reinstall, and confirm me if everything's ok already.

Thanks!

[byteborg]

Thanks for the fast response. It happens to work now. Neat stuff! Chuck Norris is living in our tracker ;-)

[zuinqstudio]

Thank you for helping us to improve the plugin. Enjoy!
