Insert element in Nested Json using another dict python
Question
I have json object and mapper like below,
Json Object:
{
'App Builder': {
'ID': '1',
'children': [{
'API Builder': {
'ID': '2'
}
}, {
'UI': {
'ID': '3',
'children': [{
'UI Builder': {
'ID': '4'
}
}, {
'Template': {
'ID': '5',
'children': [{
'Angular': {
'ID': '6'
}
}, {
'React': {
'ID': '7'
}
}, {
'PHP': {
'ID': '8'
}
}]
}
}]
}
}]
}
}
Mapper:
{
'1': ['create an app', 'create app for me', 'can you create an application?'],
'2': ['create an app using API Buider', 'make an application using API Builder', 'create API Builder application'],
'3': ['create an app using user interface', 'make an application using UI', 'create UI application'],
'4': ['create an app using UI Buider', 'make an application using UI Builder', 'create UI Builder application'],
'5': ['create an app using Template', 'make an application using Template', 'create Template application'],
'6': ['create an app using Angular', 'make an application using Angular template', 'create Angular application'],
'7': ['create an app using React', 'make an application using React template', 'create React application'],
'8': ['create an app using PHP', 'make an application using PHP template', 'create PHP application']
}
Both object contains 'ID' using this I need to append values in original json object like below,
{
"App Builder": {
"ID": "1",
"1": ["create an app", "create app for me", "can you create an application?"],
"children": [{
"API Builder": {
"ID": "2",
"2": ["create an app using API Buider", "make an application using API Builder", "create API Builder application"]
}
}, {
"UI": {
"ID": "3",
"3": ["create an app using user interface", "make an application using UI", "create UI application"],
"children": [{
"UI Builder": {
"ID": "4",
"4": ["create an app using UI Buider", "make an application using UI Builder", "create UI Builder application"]
}
}, {
"Template": {
"ID": "5",
"5": ["create an app using Template", "make an application using Template", "create Template application"],
"children": [{
"Angular": {
"ID": "6",
"6": ["create an app using Angular", "make an application using Angular template", "create Angular application"]
}
}, {
"React": {
"ID": "7",
"7": ["create an app using React", "make an application using React template", "create React application"]
}
}, {
"PHP": {
"ID": "8",
"8": ["create an app using PHP", "make an application using PHP template", "create PHP application"]
}
}]
}
}]
}
}]
}
}
I tried to get path of my required json object using below.
json_path = {}
for intent in all_walks:
ep = []
temp = s
i=0
for val in intent.split('/'):
if i==0:
ep.append(val)
temp = temp[val]
else:
temp = temp['children']
ep.append('children')
for item in temp:
if val in item.keys():
ep.append(val)
temp = item[val]
i+=1
json_path[intent] = ep
print(json_path)
it gives me,
{'App Builder': ['App Builder'], 'App Builder/API Builder': ['App Builder', 'children', 'API Builder'], 'App Builder/UI': ['App Builder', 'children', 'UI'], 'App Builder/UI/UI Builder': ['App Builder', 'children', 'UI', 'children', 'UI Builder'], 'App Builder/UI/Template': ['App Builder', 'children', 'UI', 'children', 'Template'], 'App Builder/UI/Template/Angular': ['App Builder', 'children', 'UI', 'children', 'Template', 'children', 'Angular'], 'App Builder/UI/Template/React': ['App Builder', 'children', 'UI', 'children', 'Template', 'children', 'React'], 'App Builder/UI/Template/PHP': ['App Builder', 'children', 'UI', 'children', 'Template', 'children', 'PHP']}
Again I can't use this because children is an array.
How to solve this problem.
any help would be appreciable.

I have made a recursive function to set the mapped data:
data = {
'App Builder': {
'ID': '1',
'children': [{
'API Builder': {
'ID': '2'
}
}, {
'UI': {
'ID': '3',
'children': [{
'UI Builder': {
'ID': '4'
}
}, {
'Template': {
'ID': '5',
'children': [{
'Angular': {
'ID': '6'
}
}, {
'React': {
'ID': '7'
}
}, {
'PHP': {
'ID': '8'
}
}]
}
}]
}
}]
}
}
mapper = {
'1': ['create an app', 'create app for me', 'can you create an application?'],
'2': ['create an app using API Buider', 'make an application using API Builder', 'create API Builder application'],
'3': ['create an app using user interface', 'make an application using UI', 'create UI application'],
'4': ['create an app using UI Buider', 'make an application using UI Builder', 'create UI Builder application'],
'5': ['create an app using Template', 'make an application using Template', 'create Template application'],
'6': ['create an app using Angular', 'make an application using Angular template', 'create Angular application'],
'7': ['create an app using React', 'make an application using React template', 'create React application'],
'8': ['create an app using PHP', 'make an application using PHP template', 'create PHP application']
}
def setDataFromNestedDict(data, dictKey):
if isinstance(data, dict):
if dictKey in data.keys():
data[data[dictKey]] = mapper[data[dictKey]]
for key, value in data.items():
if isinstance(value, dict):
setDataFromNestedDict(value, dictKey)
elif isinstance(value, list):
for item in value:
setDataFromNestedDict(item,dictKey)
elif isinstance(data, list):
for item in data:
setDataFromNestedDict(item,dictKey)
setDataFromNestedDict(data, 'ID')
print(data)
output:
{'App Builder': {'1': ['create an app',
'create app for me',
'can you create an application?'],
'ID': '1',
'children': [{'API Builder': {'2': ['create an app using API Buider',
'make an application using API Builder',
'create API Builder application'],
'ID': '2'}},
{'UI': {'3': ['create an app using user interface',
'make an application using UI',
'create UI application'],
'ID': '3',
'children': [{'UI Builder': {'4': ['create an app using UI Buider',
'make an application using UI Builder',

'ID': '5',
'children': [{'Angular': {'6': ['create an app using Angular',
'make an application using Angular template',

'ID': '6'}},
{'React': {'7': ['create an app using React',
'make an application using React template',
'create React application'],
'ID': '7'}},
{'PHP': {'8': ['create an app using PHP',
'make an application using PHP template',
'create PHP application'],
'ID': '8'}}]}}]}}]}}

You can use object_hook parameter of json.loads which is an optional function that will be called with the result of any object literal decoded (a dict). For example,
For the below JSON
sample_json = """{
"App Builder": {
"ID": "1",
"children": [
{
"API Builder": {
"ID": "2"
}
},
{
"UI": {
"ID": "3",
"children": [
{
"UI Builder": {
"ID": "4"
}
},
{
"Template": {
"ID": "5",
"children": [
{
"Angular": {
"ID": "6"
}
},
{
"React": {
"ID": "7"
}
},
{
"PHP": {
"ID": "8"
}
}
]
}
}
]
}
}
]
}
}"""
And with the following Mapper,
mapper = {
'1': ['create an app', 'create app for me', 'can you create an application?'],
'2': ['create an app using API Buider', 'make an application using API Builder', 'create API Builder application'],
'3': ['create an app using user interface', 'make an application using UI', 'create UI application'],
'4': ['create an app using UI Buider', 'make an application using UI Builder', 'create UI Builder application'],
'5': ['create an app using Template', 'make an application using Template', 'create Template application'],
'6': ['create an app using Angular', 'make an application using Angular template', 'create Angular application'],
'7': ['create an app using React', 'make an application using React template', 'create React application'],
'8': ['create an app using PHP', 'make an application using PHP template', 'create PHP application']
}
You can implement a object_hook function like the below one
import json
def hook(obj):
if 'ID' in obj:
key = obj["ID"]
obj.update({key: mapper[key]})
return obj
data = json.loads(sample_json, object_hook=hook)
json = json.dumps(data, indent=4)
print(json)
will produce the following output
{
"App Builder": {
"ID": "1",
"children": [
{
"API Builder": {
"ID": "2",
"2": [
"create an app using API Buider",
"make an application using API Builder",
"create API Builder application"
]
}
},
{
"UI": {
"ID": "3",
"children": [
{
"UI Builder": {
"ID": "4",
"4": [
"create an app using UI Buider",
"make an application using UI Builder",
"create UI Builder application"
]
}
},
{
"Template": {
"ID": "5",
"children": [
{
"Angular": {
"ID": "6",
"6": [
"create an app using Angular",
"make an application using Angular template",
"create Angular application"
]
}
},
{
"React": {
"ID": "7",
"7": [
"create an app using React",
"make an application using React template",
"create React application"
]
}
},
{
"PHP": {
"ID": "8",
"8": [
"create an app using PHP",
"make an application using PHP template",
"create PHP application"
]
}
}
],
"5": [
"create an app using Template",
"make an application using Template",
"create Template application"
]
}
}
],
"3": [
"create an app using user interface",
"make an application using UI",
"create UI application"
]
}
}
],
"1": [
"create an app",
"create app for me",
"can you create an application?"
]
}
}

You can use simple recursion:
data = {'App Builder': {'ID': '1', 'children': [{'API Builder': {'ID': '2'}}, {'UI': {'ID': '3', 'children': [{'UI Builder': {'ID': '4'}}, {'Template': {'ID': '5', 'children': [{'Angular': {'ID': '6'}}, {'React': {'ID': '7'}}, {'PHP': {'ID': '8'}}]}}]}}]}}
l = {'1': ['create an app', 'create app for me', 'can you create an application?'], '2': ['create an app using API Buider', 'make an application using API Builder', 'create API Builder application'], '3': ['create an app using user interface', 'make an application using UI', 'create UI application'], '4': ['create an app using UI Buider', 'make an application using UI Builder', 'create UI Builder application'], '5': ['create an app using Template', 'make an application using Template', 'create Template application'], '6': ['create an app using Angular', 'make an application using Angular template', 'create Angular application'], '7': ['create an app using React', 'make an application using React template', 'create React application'], '8': ['create an app using PHP', 'make an application using PHP template', 'create PHP application']}
def get_vals(d):
if 'ID' not in d:
return {a:get_vals(b) for a, b in d.items()}
return {**d, d['ID']:l[d['ID']], 'children':[get_vals(i) for i in d.get('children', [])]}
import json
print(json.dumps(get_vals(data), indent=4))
Output:
{
"App Builder": {
"ID": "1",
"1": [
"create an app",
"create app for me",
"can you create an application?"
],
"children": [
{
"API Builder": {
"ID": "2",
"2": [
"create an app using API Buider",
"make an application using API Builder",
"create API Builder application"
],
"children": []
}
},
{
"UI": {
"ID": "3",
"children": [
{
"UI Builder": {
"ID": "4",
"4": [
"create an app using UI Buider",
"make an application using UI Builder",
"create UI Builder application"
],
"children": []
}
},
{
"Template": {
"ID": "5",
"children": [
{
"Angular": {
"ID": "6",
"6": [
"create an app using Angular",
"make an application using Angular template",
"create Angular application"
],
"children": []
}
},
{
"React": {
"ID": "7",
"7": [
"create an app using React",
"make an application using React template",
"create React application"
],
"children": []
}
},
{
"PHP": {
"ID": "8",
"8": [
"create an app using PHP",
"make an application using PHP template",
"create PHP application"
],
"children": []
}
}
],
"5": [
"create an app using Template",
"make an application using Template",
"create Template application"
]
}
}
],
"3": [
"create an app using user interface",
"make an application using UI",
"create UI application"
]
}
}
],
}

My co-worker @Akshay pai suggested another impressive solution. The idea behind that is usage of call by reference through recursive call.
def restructure(tree_data):
if tree_data is None:
return tree_data
root_element = list(tree_data.keys())[0]
tree_data = tree_data[root_element]
tree_data["utterance"] = intent_mapper[tree_data["ID"]]
if "children" not in tree_data:
return tree_data
for child in tree_data["children"]:
restructure(child)
restructure(tree_data)
O/P:
{
"App Builder": {
"ID": "1",
"children": [
{
"API Builder": {
"ID": "2",
"utterance": [
"create an app using API Buider",
"make an application using API Builder",
"create API Builder application"
]
}
},
{
"UI": {
"ID": "3",
"children": [
{
"UI Builder": {
"ID": "4",
"utterance": [
"create an app using UI Buider",
"make an application using UI Builder",
"create UI Builder application"
]
}
},
{
"Template": {
"ID": "5",
"children": [
{
"Angular": {
"ID": "6",
"utterance": [
"create an app using Angular",
"make an application using Angular template",
"create Angular application"
]
}
},
{
"React": {
"ID": "7",
"utterance": [
"create an app using React",
"make an application using React template",
"create React application"
]
}
},
{
"PHP": {
"ID": "8",
"utterance": [
"create an app using PHP",
"make an application using PHP template",
"create PHP application"
]
}
}
],
"utterance": [
"create an app using Template",
"make an application using Template",
"create Template application"
]
}
}
],
"utterance": [
"create an app using user interface",
"make an application using UI",
"create UI application"
]
}
}
],
"utterance": [
"create an app",
"create app for me",
"can you create an application?"
]
}
