I am tryinging to create a nested Json structure as follows:
Example Json:
{
"id" : "de",
"Key" : "1234567",
"from" : "test@test.com",
"expires" : "2018-04-25 18:45:48.3166159",
"command" : "method.exec",
"params" : {
"method" : "cmd",
"Key" : "default",
"params" : {
"command" : "testing 23"
}
}
I am trying to do this from an OrderedDict. I am not sure of the correct way to structure the OrderedDict so that the correct Json is produced.
Python Code:
json_payload = OrderedDict(
[('id', id),
('Key', keystore),
('from', 'test@test.com'),
('expires', expires),
('command', 'method.exec')]
# What goes here for the params section??
)
print json.dumps(json_payload, indent=4, default=str)
You missed a }
at the end of your JSON data.
import json
import collections
data = {
"id" : "de",
"Key" : "1234567",
"from" : "test@test.com",
"expires" : "2018-04-25 18:45:48.3166159",
"command" : "method.exec",
"params" : {
"method" : "cmd",
"Key" : "default",
"params" : {
"command" : "testing 23"
}
}}
data_str = json.dumps(data)
result = json.loads(data_str, object_pairs_hook=collections.OrderedDict)
print(result)
Output:
OrderedDict(
[
('id', 'de'),
('Key', '1234567'),
('from', 'test@test.com'),
('expires', '2018-04-25 18:45:48.3166159'),
('command', 'method.exec'),
('params',
OrderedDict(
[
('method', 'cmd'),
('Key', 'default'),
('params',
OrderedDict(
[
('command', 'testing 23')
]
)
)
]
)
)
]
)
A few things. id
is a keyword. You can just pass a dictionary as a parameter.
ids = "de"
keystore = "1234567"
expires = "2018-04-25 18:45:48.3166159"
pdict = {
"method" : "cmd",
"Key" : "default",
"params" : {
"command" : "testing 23"
}
}
json_payload = OrderedDict(
[('id', id),
('Key', keystore),
('from', 'test@test.com'),
('expires', expires),
('command', 'method.exec'),
('params',pdict )
]
)
print(json.dumps(json_payload, indent=4, default=str))
Using @haifzhan's output as the input delivered exactly what was required.
payload = OrderedDict(
[
('id', 'de'),
('Key', '1234567'),
('from', 'test@test.com'),
('expires', '2018-04-25 18:45:48.3166159'),
('command', 'method.exec'),
('params',
OrderedDict(
[
('method', 'cmd'),
('Key', 'default'),
('params',
OrderedDict(
[
('command', 'testing 23')
]
)
)
]
)
)
]
)
print json.dumps(json_payload, indent=4, default=str)
WORKING !!!
Mostly When We serialize querysets instead of model instances Ex:
serialized_data = SnippetSerializer(MyModel.objects.all(), many=True)
Output:
[
OrderedDict([('code', 'ABC'), ('quantity', 5.0)]),
OrderedDict([('code', 'GGG'), ('quantity', 4.0)])
]
We can convert it to json like this: -
from rest_framework.renderers import JSONRenderer
from rest_framework.parsers import JSONParser
import io
result = JSONRenderer().render(serialized_data)
output_stream = io.BytesIO(result)
data = JSONParser().parse(output_stream)
print(data)
Output:
[
{'code': 'ABC', 'quantity': 5.0},
{'code': 'GGG', 'quantity': 4.0}
]
