Hi after trying for a long time I finally managed to do the below changes
in SQLHTML.py, represent function.
def represent(field, value, record):
f = field.represent
if not callable(f):
return str(value)
n = f.func_code.co_argcount - len(f.func_defaults or [])
if getattr(f, 'im_self', None):
n -= 1
if n == 1:
return f(value)
elif n == 2:
return f(value, record)
#My part of the code
elif n == 3:
return f(value, record,field)
else:
raise RuntimeError("field representation must take 1 or 2 args")
The above addition to the represent function means we can now highlight
some values in a grid by checking if they are equal to the first row's
value of the same field.
