I’m trying to import from a Vanilla forum using the instructions posted here. However, I get the following error when I run the vanilla.rb import script:
Loading existing groups...

Traceback (most recent call last):

I’ve tried changing the MySQL database character set to UTF8 following the instructions here and then re-exporting the porter file, but that didn’t resolve the issue. Any suggestions?
You can google stuff about UTF-8 encoding. You need to do something that will coerce the table into UTF-8. The time that I did it, there were further complications because some rows were in one format and others in another format. I think that I did some nonsense where I coerced things on a value-by-value basis.
Oh. It’s aweful. You best bet, based on a vague recollection of a single time I did this over a year ago, is to play around with as many different conversions as you can until you can finally hit on one that works for all or most data. I think that I did a bunch of one-by-one transformations that ended up being a waste of time when I stumbled on some conversion that worked for all (most?) data.
Here is what I did. Use at your own risk. (This was vbulletin, FWIW).
def char_map(raw_original)
raw = raw_original.dup
debug = false # (raw.length > 50)
# windows 1252
all = ''
win_encoded = ''
### WIN1252 encoding
win_encoded = ''
begin
win_encoded = raw.force_encoding('utf-8').encode("Windows-1252",
invalid: :replace, undef: :replace, replace: ""
).force_encoding('utf-8').scrub
rescue => e
puts "\n#{'-'*50}\nWin1252 failed for \n\n#{raw}\n\n"
win_encoded = ''
end
### ISO 8859 encoding
iso_encoded = ''
if all.length == 0 && win_encoded.length > 0 && win_encoded != raw
all = (debug ? "Win1252--" : '') + win_encoded
else
all = raw
end
all = old_char_map(all)
all
end
Logramos que esto funcionara añadiendo un simple comando para codificar el archivo como UTF-8 al leerlo, usando algo como encode\"UTF-8\" en las líneas 76-80 del script de importación vanilla.rb.
Solo estoy esperando la confirmación de la sintaxis exacta del chico que lo hizo por línea de comandos. Actualizaré esto cuando la tenga.
Trabajé en este proceso hace solo un par de meses (y no soy desarrollador ) y logré migrar con éxito un foro Vanilla autoalojado a Discourse autoalojado. Algo que fue clave para mí fue asegurarme, al exportar los datos con Vanilla Porter, de seleccionar “Vanilla 2” como el Source Forum Type en el primer menú desplegable.
Si mal no recuerdo, no volví a encontrar el error UTF-8 al usar el script más reciente de Vanilla Porter y el tipo de foro “Vanilla 2”.
Si esas dos sugerencias no marcan la diferencia en tu importación, por favor, proporciona algunos detalles sobre los pasos que has seguido hasta ahora y exactamente lo que estás viendo. A veces hay ligeras variaciones en el “mismo error” que pueden marcar una gran diferencia al solucionar problemas.
