Related to https://github.com/marshmallow-code/marshmallow/issues/315.
Looks like the fixes in #744 and #750 are somehow wrong.
It works in the general case where
is a collection. But it might not be the case if it is not. For instance, if it contains an envelope that is removed in a
decorator.
For instance, run the
1
| test_decorated_processors |
test with a slight modification: add
to the last
.

| py
(pass_original&＃061;True)
def decrement_value(self, item, **kwargs):
item[&＃039;value&＃039;] -&＃061; 1
return item |
It fails because this piece of code expects
to be a
(
1
| [{&＃039;value&＃039;: 4}, {&＃039;value&＃039;: 4}] |
), but it is a
(
1
| {&＃039;data&＃039;: [{&＃039;value&＃039;: &＃039;4&＃039;}, {&＃039;value&＃039;: &＃039;6&＃039;}] |
):

| py
if pass_original:
data &＃061; [
processor(item, original_data&＃061;original)
for item, original in zip(data, original_data)
]
else:
data &＃061; [processor(item) for item in data] |
only grabs a single element (
), which is wrong.
I don't see any solution to this. I'm afraid the idea in #315 works in the typical case but can't work in all cases.
