ActionView::TemplateError (incompatible character encodings: ASCII-8BIT and UTF-8) in several Views

Added by Norbert Melzer at 2012-07-25 11:35 am

I have managed to install passenger and chiliproject yesterday.

But there are some problems, very often when I am doing something then I get the 500.html served. The logs tell me the following (example with gantt-chart):

Rendering /home/nobbz_de/sites/nobbz.de/subdoms/devel/httpdocs/public/500.html (500 Internal Server Error)

I encounter this problem with many subsites, even with creating a project.

I found a workaround by adding .dup.force_encoding(Encoding::UTF_8), and I also tried it in the gantts (as you see in the trace), but I think it cant be that I have to change nearly every template.

I encountered this problem so far with creating a project (semi-fixed), gantt, calender, tickets in general. Perhaps there are more which don't work.

Is there a way to easily fix it? Or should I file this as a bug?

RE: ActionView::TemplateError (incompatible character encodings: ASCII-8BIT and UTF-8) in several Views - Added by Norbert Melzer at 2012-07-25 03:25 pm

I found another workaround:

When I switch the interface-language to english this problem seems to be away. But for my users it would be easier if I reenable german soon.

Also I fear that there will be problems as soon as someone uses umlauts in an issue.

IIRC rails 2.3 is not compatible to 1.9.3 (in the sense that it might work but is not guaranteed to), could you try with 1.9.2?

Furthermore, are you using the mysql, mylsq2 or pg adapter and is your database encoding correct?

OK, there is the next problem related to this.

Even with english as the language, I cant create a new issue, perhaps there are other forms not working...

It looks like the same problem, but somewhere else

It looks like everything you get from the DB is ASCII tagged instead of UTF-8 (meaning: it might be an UTF-8-valid byte stream, but ruby doesn't know it and treats it as ASCII).

Anyway, see the above questions.

I will try 1.9.2, but could take a while, since I have to reconf the whole server thing and reinstall that bunch of gems…

Anyway, on [[https://www.chiliproject.org/projects/chiliproject/wiki/Installation]] is mentioned, that Chili should work with 1.9.3, so I have choosen this, to stay "at the edge".

Furthermore, are you using the mysql, mylsq2 or pg adapter and is your database encoding correct?

I use mysql and created the database-table as mentioned in the installation page. So I assume that db-encoding is correct.

Yes, we try to be compatible to 1.9.3, the trial was just to try to confirm that it's not related to 1.9.3 :-)

Furthermore, are you using the mysql, mylsq2 or pg adapter and is your database encoding correct?

I use mysql and created the database-table as mentioned in the installation page. So I assume that db-encoding is correct.

Ah, the mysql gem has been replaced by the mysql2 gem. The mysql gem isn't maintained anymore and is known to not be compatible with 1.9 in many situations. Please change the database adapter from mysql to mysql2 in your conf/database.yml and restart ChiliProject, that should be enough to correct the problem.

OK, just finished to download and compile 1.9.2-p320, but before installing passenger and rails for that I tried:

and it works so far. Tried all I know it did not work before. All seems running. I consider this solved.

Thank you!
