When calling this method, you should have defined patterns (in the

PATTERN class attribute) with a list containing tuples of regexp

and the associated type, for example::
|
|
|

PATTERNS = [(re.compile('^VIR(EMENT)? (?P<text>.*)'), FrenchTransaction.TYPE_TRANSFER),

|
|
FrenchTransaction.TYPE_CARD)
|
|
]
|
|
|
|
In regexps, you can define this patterns:
|
|
|
|
* text: part of label to store in simplified label
|
|
* category: part of label representing the category
|
|
* yy, mm, dd, HH, MM: date and time parts
