i have this document in mongodb

I want to update nested array document, for instance the name with gender-tittle. This have value schoolA and i want to change to adult like the body. I give the parameter number of fileId in the post request and in body i pass this
post request : localhost/sessionUpdate/4
and body:
{
"name": "gender-title",
"value": "adultos"
}
flask
#app.route('/sessionUpdate/<string:a>', methods=['PUT'])
def sessionUpdate(a):
datas=request.json
r=str(datas['name'])
r2=str(datas['value'])
print(r,r2)
r3=collection.update_one({'fileId':a, 'metadata.addtionalInformation':r}, {'$set':{'metadata.addtionalInformation.$.value':r2}})
return str(r3),200
i'm getting the 200 but the document don't update with the new value.
As you are using positional operator $ to work with your array, make sure your select query is targeting array element. You can see in below query that it is targeting metadata.addtionalInformation array with the condition that name: "gender-title"
db.collection.update({
"fileId": 4,
"metadata.addtionalInformation.name": "gender-title"
},
{
"$set": {
"metadata.addtionalInformation.$.value": "junior"
}
})

I have Attribute Patterned (https://www.mongodb.com/blog/post/building-with-patterns-the-attribute-pattern) field that looks like this:
"cmr_diag": [{
"name": "shd?",
"value": {
"$numberDouble": "1"
}
}, {
"name": "ischemic_hd",
"value": {
"$numberDouble": "1"
}
}, {
"name": "non-ischemic_dcmp",
"value": {
"$numberDouble": "1"
}
}, {
"name": "myocarditis",
"value": {
"$numberDouble": "0"
}
}, {
"name": "hcm",
"value": {
"$numberDouble": "0"
}
}, {
"name": "amyloidosis",
"value": {
"$numberDouble": "0"
}
}, {
"name": "toxic_cmp",
"value": {
"$numberDouble": "1"
}
.
.
.
I'd like to create an aggregation pipeline that finds all patients with ONLY ischemic_hd, while all other possible illnesses are 0. I am not sure how to create this query however?
You can use $elemMatch to identify patients with a specific attribute.
If you want to exclude everything else, use $reduce to sum up the value of all of the attributes, and match where count = 1.
db.collection.aggregate([
{$match: {
cmr_diag: {
$elemMatch: {
name: "ischemic_hd",
value: { "$numberDouble": "1" }
}
}
}},
{$addFields: {
diagcount: {
$reduce: {
input: "$cmr_diag",
initialValue: 0,
in: {$sum: ["$$value","$$this.value.$numberDouble"]}
}
}
}},
{$match: { diagcount: 1}}
])
TASK:
I am using a API call to get JSON data from our TeamCity CI tool.
We need to identify all those builds which are using old version of msbuild.
We can identify from this API call data
{
"name": "msbuild_version",
"value": "15.0"
}
At the moment i am saving the entire API call data to a file; however i will later integrate the API call to the same script.
Now to the question at hand; How can i filter this above property i.e. msbuild_version, to say msbuild_version < 15.0 (i.e. all msbuild less than version 15.0) and display the corresponding 'id' and 'projectName' under 'buildType'; e.g.
"id": "AIntegration_BTool_BToolBuilds_DraftBuild",

My Solution till now
And my code snippet till now
import json
with open('UnArchivedBuilds.txt') as api_call:
read_content = json.load(api_call)
#for project in read_content['project']:
# print (project.get('buildTypes'))
for project in read_content['project']:
# print (project['id'])
print (project['buildTypes']['buildType'])
I am not able to decide on the hierarchy of the JSON to print the relevant data (i.e id and projectName) wherever msbuild_version is less than 15.0
I had a look at your JSON data which was broken. In order to work with the snippet you provided I fixed the malformed data and removed unneeded parts to decrease clutter:
{
"project": [{
"buildTypes": {
"buildType": [{
"id": "AIntegration_BTool_BToolBuilds_DraftBuild",
"projectName": "A Integration / B Tool / VAR Builds"
},
{
"id": "AIntegration_BTool_BToolBuilds_ContinuousBuildIntegration",
"projectName": "A Integration / B Tool / VAR Builds"
}]
}
}]
}
As per my comment above I suggested recursion or using a schema validator to boil the JSON data down. However, as a quick-and-dirty approach and due to the weird structure of your dataset, I decided to do a multi-iteration over some parts of your data. Iterating over the same data is quite ugly and considered to be bad practice in most cases.
Assuming the data is stored in a file called input.json, the following snippet should give you the desired output:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import json
with open('input.json') as f:
data = json.load(f)
projects = (element for element in data.get('project'))
build_types = (element.get('buildTypes') for element in projects)
build_types = (element.get('buildType') for element in build_types)
for item in build_types:
for element in item:
identifier = element.get('id')
project_name = element.get('projectName')
print('{} --> {}'.format(identifier, project_name))
Printing:
AIntegration_BTool_BToolBuilds_DraftBuild --> A Integration / B Tool / VAR Builds
AIntegration_BTool_BToolBuilds_ContinuousBuildIntegration --> A Integration / B Tool / VAR Builds
I want to fetch the value of each api3 in this json object where each array has api3 value.
{
"count": 10,
"result": [
{
"type": "year",
"year": {
"month": {
"api1": {
"href": "https://Ap1.com"
},
"api2": {
"href": "FETCH-CONTENT"
},
"api3": {
"href": "https://Ap3.com"
},
"api4": {
"href": "https://Ap4.com"
}
},
"id": "sdvnkjsnvj",
"summary": "summeryc",
"type": "REST",
"apiId": "mlksmfmksdfs",
"idProvider": {
"id": "sfsmkfmskf",
"name": "Apikey"
},
"tags": []
}
},
{
"type": "year1",
"year": {
"month": {
"api1": {
"href": "https://Ap11.com"
},
"api2": {
"href": "FETCH-CONTENT-1"
},
"api3": {
"href": "https://Ap13.com"
},
"api4": {
"href": "https://Ap14.com"
}
},
"id": "sdvnkjsnvj",
"summary": "summeryc",
"type": "REST",
"apiId": "mlksmfmksdfs",
"idProvider": {
"id": "sfsmkfmskf",
"name": "Apikey"
},
"tags": []
}
},
I am able to get the whole json object and first value inside it.
with open('C:\python\examplee.json','r+') as fr:
data = json.load(fr)
print(data["result"])
Thank you in advance for helping me figuring this.
For each element in list of result key, get the value for the nested dictionary within item
print([item['year']['month']['api3'] for item in data['result']])
The output will be [{'href': 'https://Ap3.com'}, {'href': 'https://Ap13.com'}]
Or if you want to get the href value as well
print([item['year']['month']['api3']['href'] for item in data['result']])
The output will be
['https://Ap3.com', 'https://Ap13.com']
So your whole code will look like
data = {}
with open('C:\python\examplee.json','r+') as fr:
data = json.load(fr)
print([item['year']['month']['api3']['href'] for item in dct['result']])
Looks like your JSON schema is static so you can just use this:
print([x['year']['month']['api3']['href'] for x in data['result']])
will return you:
['https://Ap3.com', 'https://Ap13.com']
I have got this response from the Facebook Graph API:

I am willing to extract the URL part of the graph API response with field taggable_friends.
I have tried something like this:
for friends in data_json_liked_pages['taggable_friends']['data']:
friend_url = friends['picture']['data']['url']
print friend_url
I am getting the following error:

which im trying to parse using the json module in python. I am only intrested in getting the following information out of it.
Name Value
operational-status Value
health-state Value
Here is what i have tried.
in the below script data is the json returned from a webpage
json = json.loads(data)
healthstate= json['response']['context']['operational-status']
operationalstatus = json['response']['context']['health-status']
Unfortunately i think i must be missing something as the above results in an error that indexes must be integers not string.
if I try
healthstate= json['response'][0]
it errors saying index 0 is out of range.
Any help would be gratefully received.
json['response']['context'] is a list, so that object requires you to use integer indices.
Each item in that list is itself a dictionary again. In this case there is only one such item.
To get all "name": "health-state" dictionaries out of that structure you'd need to do a little more processing:
[attr['value'] for attr in json['response']['context'][0]['attributes'] if attr['name'] == 'health-state']
would give you a list of of matching values for health-state in the first context.
Demo:
>>> [attr['value'] for attr in json['response']['context'][0]['attributes'] if attr['name'] == 'health-state']
[u'ok']
You have to follow the data structure. It's best to interactively manipulate the data and check what every item is. If it's a list you'll have to index it positionally or iterate through it and check the values. If it's a dict you'll have to index it by it's keys. For example here is a function that get's the context and then iterates through it's attributes checking for a particular name.
def get_attribute(data, attribute):
for attrib in data['response']['context'][0]['attributes']:
if attrib['name'] == attribute:
return attrib['value']
return 'Not Found'
>>> data = json.loads(s)
>>> get_attribute(data, 'operational-status')
u'ok'
>>> get_attribute(data, 'health-state')
u'ok'
json['reponse']['context'] is a list, not a dict. The structure is not exactly what you think it is.
For example, the only "operational status" I see in there can be read with the following:
json['response']['context'][0]['attributes'][0]['operational-status']
