If you want to specify the DataStructure, you need to also addField(). I've
written a
addFieldsFromDataStructure() method for this.
Didn't know that method existed. I'll give it a try.
I don't think I ever posted it to Dabo. It goes like this:
def addFieldsFromDataStructure(self):
max_fill = 0
for field in self.DataStructure:
if field[3] is not None:
fill = len("%s.%s" % (field[3], field[4]))
max_fill = max(max_fill, fill)
for field in self.DataStructure:
fill = " " * (max_fill - len("%s.%s" % (field[3], field[4])))
if field[3] is not None:
self.addField("%s.%s %sas %s" % (field[3], field[4],
fill, field[0]))
Most of the code has to do with indentation.
Simple is beautiful.
I do it this way :
for field in self.DataStructure:
alias = field[0]
tabla = field[3]
campo = field[4]
if tabla:
self.addField('{}.{}'.format(tabla, campo), alias)
If you'd like to go the 'table.field as alias' way, then replace the
last line with "self.addField('{}.{} as {}'.format(tabla, campo, alias))".
If you want to indent just do "self.addField('{}.{} as {}'.format(tabla,
campo, alias).rjust(40))".
If you want finer indenting (first line is just before the loop) :
totLen = max((len('{}.{}'.format(i[3], i[4])) for i in self.DataStructure))
...
..
.
self.addField('{}.{} as {}'.format(tabla, campo,
alias).rjust(totLen))
