Hi,
the problem occurs if you have columns with byte data.
to exclude them of the serialization is used
def serializable_hash(options=nil)
options ||= {}
options.merge!( :except=> [:MY_BYTEDATA_COLUMN] ) if
options[:except].blank?
super(options)
end

Hi guys,
I have a simple controller
def gmap
@intentsearches = Intentsearch.all
logger.info @intentsearches
respond_to do |format|
format.html {render :gmap}
format.xml {render :xml => @intentsearches }
format.json { render :json => @intentsearches }
end
end
and want a json response, but i do get the following error
Completed 500 Internal Server Error in 107ms
ArgumentError (redundant UTF-8 sequence):
app/controllers/intentsearches_controller.rb:103:in `gmap'

I am sending a http request with only one header param
Accept : application/json
Does anyone know about this issue?
Best,
philip
update:
some more investigation revealed the following.
when i do call the to_json method in the console on a single object it
all works fine.
the error occurs only when i get a collection of objects.
