werkzeug.OrderedMultiDict

class werkzeug.OrderedMultiDict(mapping=None)[source]

Works like a regular MultiDict but preserves the order of the fields. To convert the ordered multi dict into a list you can use the items() method and pass it multi=True.

In general an OrderedMultiDict is an order of magnitude slower than a MultiDict.

note

Due to a limitation in Python you cannot convert an ordered multi dict into a regular dict by using dict(multidict). Instead you have to use the to_dict() method, otherwise the internal bucket objects are exposed.

Methods

__init__([mapping])
add(key, value)
clear(() -> None.  Remove all items from D.)
copy() Return a shallow copy of this object.
deepcopy([memo]) Return a deep copy of this object.
fromkeys(...) v defaults to None.
get(key[, default, type]) Return the default value if the requested data doesn’t exist.
getlist(key[, type])
has_key((k) -> True if D has a key k, else False)
items(*a, **kw) Like iteritems(), but returns a list.
iteritems([multi])
iterkeys()
iterlists()
iterlistvalues()
itervalues()
keys(*a, **kw) Like iterkeys(), but returns a list.
lists(*a, **kw) Like iterlists(), but returns a list.
listvalues(*a, **kw) Like iterlistvalues(), but returns a list.
pop(key[, default])
popitem()
popitemlist()
poplist(key)
setdefault(key[, default]) Returns the value for the key if it is in the dict, otherwise it returns default and sets that value for key.
setlist(key, new_list)
setlistdefault(key[, default_list])
to_dict([flat]) Return the contents as regular dict.
update(mapping)
values(*a, **kw) Like itervalues(), but returns a list.
viewitems(...)
viewkeys(...)
viewvalues(...)
