key alias for jsonclasses
Is it possible to get the value from aliases? this happens because the key value is too long to call the attributes
eg: here api returns something with repetitive or long text
data = {
'sticker': {
'stickerCollectionSummary': {
'bannerUrl': str,
'collectionId': str,
# ...
},
'stickerId': str,
# ...
},
# ...
}
and making the jsonclass of this is tedious and repetitive with the name
@jsonclass
class StickerCollectionSummary:
bannerUrl: str
collectionId: str
# ...
@jsonclass
class Sticker:
stickerCollectionSummary: StickerCollectionSummary
stickerId: str
# ...
sticker: Sticker = ... # get the object
# for get banner
sticker.stickerCollectionSummary.bannerUrl #too long
# for get collectionId
sticker.stickerCollectionSummary.collectionId # too long
# for get sticker id
sticker.stickerId # repetitive
If suggestions are accepted, I would ask that a method be added to get the key from the dict, to use the value in an alias as shown below.
# In this case, I decided to assume that there is a method fkey
# that, when starting the class, assigns the value from what is obtained from the key
# info: fkey is 'fetch key' or 'from key'
@jsonclass
class StickerCollectionSummary:
bannerUrl: str
id: str = types.str.fkey('collectionId')
@jsonclass
class Sticker:
collection: StickerCollectionSummary = types.fkey('stickerCollectionSummary')
id: str = types.str.fkey('stickerId')
Hi @ViktorSky, I guess we can.
How is it done? I have been reading the documentation but I have only found the references with ´linkedBy/linkedTo´, I have also read the source code, but it is a bit confusing to handle the modifiers
Hi @ViktorSky, do you mean nested models?
No, I meant to specify the key for the field.
@jsonclass
class User:
name: str = types.str.alias('userName')
type: int = types.int.alias('userType')
data = {
'userName': 'John',
'userType': 0
}
user = User(**data)
print(user)
"""
User(userName='John')
"""
print(user.name)
"""
John
"""
