I have json data that looks like this:
[['tom', 324],['dick', 246],['harry', 112]]
I want to be able to display html like follows:
Line: 324 - tom
Line: 246 - dick
Line: 112 - harry
So....I made a function to reformat my data and use represent to run the
data through the function:
Field('username', 'json', represent = lambda usernames, row: displayrecords(
usernames)),
Here is the function:
def displayrecords(value):
values = []
for x, y in value:
values.append(str('Line: '+ str(y) + ' ~ ' + x))
return values
This function then give me a list as follows:
['Line: 324 ~ tom', 'Line: 246 ~ dick', 'Line: 112 ~ harry']
Now, whenever I change the field line to this
Field('username', 'json', represent = lambda usernames, row:
XML('<br>'.join(displayrecords(usernames)))),
I get the following traceback:

Where am I going wrong here?
