A really simple noob question. How do I place variables in this json_body variable? The problem is with all the quotation marks. I can't use the .format string method for this as the json_body variable isn't holding a simple string.
from influxdb import InfluxDBClient
json_body = [
{
"measurement": "cpu_load_short",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2009-11-10T23:00:00Z",
"fields": {
"value": 0.64
}
}
]
client = InfluxDBClient('localhost', 8086, 'root', 'root', 'example')
client.create_database('example')
client.write_points(json_body)
Source: https://github.com/influxdata/influxdb-python#examples
So, for example, how do I get a variable in there, e.g.
"value": 0.64
to:
"value": variable_name?
In the example code, all values are hard-coded.
The right way is to build the dictionary as a Python object, using your variables, then use json.dumps.
For example
import json
x = 42
d = {'answer': x}
print(json.dumps(d))
This prints
{"answer": 42}
As you surmised in your question, you must not use string interpolation because the values you interpolate may contain quotes. Good observation!
EDIT
You mentioned in a comment that you had a larger object. Perhaps you want to do something like this?
def create_json_body_for_value(value):
return json.dumps([
{
"measurement": "cpu_load_short",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2009-11-10T23:00:00Z",
"fields": {
"value": value
}
}
])

I am in no way an expert with groovy so please don't hold that against me.
I have JSON that looks like this:
{
"metrics": [
{
"name": "metric_a",
"help": "This tracks your A stuff.",
"type": "GAUGE",
"labels": [
"pool"
],
"unit": "",
"aggregates": [],
"meta": [
{
"category": "CAT A",
"deployment": "environment-a"
}
],
"additional_notes": "Some stuff (potentially)"
},
...
]
...
}
I'm using it as a source for automated documentation of all the metrics. So, I'm iterating through it in various ways to get the information I need. So far so good, I'm most of the way there. The problem is this all needs to be organized per the deployment environment. Meaning, multiple metrics will share the same value for deployment.
My thought was I could create a map with deployment as the key and the metric name for any metric that has a matching deployment as the value. Once I have that map, it should be easy for me to organize things the way they should be. I can't figure out how to do that. The result is all the metric names are added which is expected since I'm not doing anything to filter them out. I was thinking that groupBy would make sense here but I can't figure out how to use it effectively and frankly I'm not sure it will solve my problem by itself. Here is my code so far:
parentChild = [:]
children = []
metrics.each { metric ->
def metricName = metric.name
def depName = metric.meta.findResult{ it.deployment }
children.add(metricName)
parentChild.put(depName, children)
}
What is the best way to create a new map where the values for each key are based off a specific condition?
EDIT: The desired result would be each key in the resulting map would be a unique deployment value from all the metrics (as a string). Each value would be name of each metric that contains that deployment (as an array).
[environment-a:
[metric_a,metric_b,metric_c,...],
environment-b:
[metric_d,metric_e,metric_f,...]
...]
I would use a combo of withDefault() to pre-fill each map-entry value with a fresh TreeSet-instance (sorted no-duplicates set) and standard inject().
I reduced your sample data to the bare minimum and added some new nodes:
import groovy.json.*
String input = '''\
{
"metrics": [
{
"name": "metric_a",
"meta": [
{
"deployment": "environment-a"
}
]
},
{
"name": "metric_b",
"meta": [
{
"deployment": "environment-a"
}
]
},
{
"name": "metric_c",
"meta": [
{
"deployment": "environment-a"
},
{
"deployment": "environment-b"
}
]
},
{
"name": "metric_d",
"meta": [
{
"deployment": "environment-b"
}
]
}
]
}'''
def json = new JsonSlurper().parseText input
def groupedByDeployment = json.metrics.inject( [:].withDefault{ new TreeSet() } ){ res, metric ->
metric.meta.each{ res[ it.deployment ] << metric.name }
res
}
assert groupedByDeployment.toString() == '[environment-a:[metric_a, metric_b, metric_c], environment-b:[metric_c, metric_d]]'
If your metrics.meta array is supposed to have a single value, you can simplify the code by replacing the line:
metric.meta.each{ res[ it.deployment ] << metric.name }
with
res[ metric.meta.first().deployment ] << metric.name
I have the below response payload and I just want to check the amount == 1000 if it's matching then I just want to get the entire column as output.
Sample Input:
{
"sqlQuery": "select SET_UNIQUE, amt as AMOUNT from transactionTable where SET_USER_ID=11651 ",
"message": "2 rows selected",
"row": [
{
"column": [
{
"value": "22621264",
"name": "SET_UNIQUE"
},
{
"value": "1000",
"name": "AMOUNT"
}
]
},
{
"column": [
{
"value": "226064213",
"name": "SET_UNIQUE"
},
{
"value": "916",
"name": "AMOUNT"
}
]
}
]
}
Expected Output:
"column": [
{
"value": "22621264",
"name": "SET_UNIQUE"
},
{
"value": "1000",
"name": "AMOUNT"
}
]
The above sample I just want to fetch the entire column if the AMOUNT value will be 1000.
I just tried below to achieve this but no luck.
1. row[*].column[?(#.value==1000)].column
2. row[*].column[?(#.value==1000)]
I don't want to do this by using index. Because It will be change.
Any ideas please?
I think you'd need nested expressions, which isn't something that's widely supported. Something like
$.row[?(#.column[?(#.value==1000)])]
The inner expression returns matches for value==1000, then the outer expression checks for existence of those matches.
Another alternative that might work is
$.row[?(#.column[*].value==1000)]
but this assumes some implicit type conversions that may or may not be supported.
I have a list example_list contains two dict objects, it looks like this:
[
{
"Meta": {
"ID": "1234567",
"XXX": "XXX"
},
"bbb": {
"ccc": {
"ddd": {
"eee": {
"fff": {
"xxxxxx": "xxxxx"
},
"www": [
{
"categories": {
"ppp": [
{
"content": {
"name": "apple",
"price": "0.111"
},
"xxx: "xxx"
}
]
},
"date": "A2020-01-01"
}
]
}
}
}
}
},
{
"Meta": {
"ID": "78945612",
"XXX": "XXX"
},
"bbb": {
"ccc": {
"ddd": {
"eee": {
"fff": {
"xxxxxx": "xxxxx"
},
"www": [
{
"categories": {
"ppp": [
{
"content": {
"name": "banana",
"price": "12.599"
},
"xxx: "xxx"
}
]
},
"date": "A2020-01-01"
}
]
}
}
}
}
}
]
now I want to filter the items and only keep "ID": "xxx" and the correspoding value for "price": "0.111", expected result can be something similar to :
[{"ID": "1234567", "price": "0.111"}, {"ID": "78945612", "price": "12.599"}]
or something like {"1234567":"0.111", "78945612":"12.599" }
Here's what I've tried:
map_list=[]
map_dict={}
for item in example_list:
#get 'ID' for each item in 'meta'
map_dict['ID'] = item['meta']['ID']
# get 'price'
data_list = item['bbb']['ccc']['ddd']['www']
for data in data_list:
for dataitem in data['categories']['ppp']
map_dict['price'] = item["content"]["price"]
map_list.append(map_dict)
print(map_list)
The result for this doesn't look right, feels like the item isn't iterating properly, it gives me result:
[{"ID": "78945612", "price": "12.599"}, {"ID": "78945612", "price": "12.599"}]
It gave me duplicated result for the second ID but where is the first ID?
Can someone take a look for me please, thanks.
Update:
From some comments from another question, I understand the reason for the output keeps been overwritten is because the key name in the dict is always the same, but I'm not sure how to fix this because the key and value needs to be extracted from different level of for loops, any help would be appreciated, thanks.
as #Scott Hunter has mentioned, you need to create a new map_dict everytime you are trying to do this. Here is a quick fix to your solution (I am sadly not able to test it right now, but it seems right to me).
map_list=[]
for item in example_list:
# get 'price'
data_list = item['bbb']['ccc']['ddd']['www']
for data in data_list:
for dataitem in data['categories']['ppp']:
map_dict={}
map_dict['ID'] = item['meta']['ID']
map_dict['price'] = item["content"]["price"]
map_list.append(map_dict)
print(map_list)
But what are you doing here is that you are basically just "forcing" your way through ... I recommend you to take a break and check out somekind of tutorial, which will help you to understand how it really works in the back-end. This is how I would have written it:
list_dicts = []
for example in example_list:
for www in item['bbb']['ccc']['ddd']['www']:
for www_item in www:
list_dicts.append({
'ID': item['meta']['ID'],
'price': www_item["content"]["price"]
})
Good luck with this problem and hope it helps :)
You need to create a new dictionary for map_dict for each ID.
Thanks for taking the time out to read this. I want to find a way of parsing the json below. I'm really struggling to get the correct values out. I am getting this info from an API, and want to save this data into a database.
I am really struggling to parse info_per_type because I first need to get the available_types. This can change depending on the info available (i.e. I might get 2 different types in the next call, there's a total of 4) so my code needs to be flexible enough to deal with this
```
{
"data": [
{
"home_team": "Ravenna",
"id": 82676,
"available_types": [
"type_a",
"type_b"
],
"info_per_type": {
"type_a": {
"options": {
"X": 0.302,
"X2": 0.61,
"X3": 0.692,
"X4": 0.698,
"X5": 0.39,
"X6": 0.308
},
"status": "pending",
"output": "12",
"option_values": {
"X": 3.026,
"X2": 1.347,
"X3": 1.516,
"X4": 1.316,
"X5": 2.936,
"X6": 2.339
}
},
"type_b": {
"options": {
"yes": 0.428,
"no": 0.572
},
"status": "pending",
"output": "no",
"option_values": {
"yes": null,
"no": null
}
}
}
}
]
}```
So far, I can get the available_types out. But after that, I'm stuck. I have tried eval and exec but I can't seem to get that working either.
```
r = requests.get(url, headers=headers).text
arrDetails = json.loads(r)
arrDetails = arrDetails['data']
x = arrDetails[0]['available_types']
print(x[1]) #I get the correct value here
y = exec("y = arrDetails[0]['info_per_type']['" + x[1] + "']")
print(y)```
When I print out y I get None. What I want is some way to reference that part of the json file, as the results within that node are what I need. Any help would be HIGHLY appreciated!
Something like this should work :
for row in arrDetails['data']:
for available_type in row['available_types']:
print(row['info_per_type'][available_type])
I have a nested dictionary with keys and values as shown below.
j = {
"app": {
"id": 0,
"status": "valid",
"Garden": {
"Flowers":
{
"id": "1",
"state": "fresh"
},
"Soil":
{
"id": "2",
"state": "stale"
}
},
"BackYard":
{
"Grass":
{
"id": "3",
"state": "dry"
},
"Soil":
{
"id": "4",
"state": "stale"
}
}
}
}
Currently, I have a python method which returns me the route based on keys to get to a 'value'. For example, if I want to access the "1" value, the python method will return me a list of string with the route of the keys to get to "1". Thus it would return me, ["app","Garden", "Flowers"]
I am designing a service using flask and I want to be able to return a json output such as the following based on the route of the keys. Thus, I would return an output such as below.
{
"id": "1",
"state": "fresh"
}
The Problem:
I am unsure on how to output the result as shown above as I will need to parse the dictionary "j" in order to build it?
I tried something as the following.
def build_dictionary(key_chain):
d_temp = list(d.keys())[0]
...unsure on how to
#Here key_chain contains the ["app","Garden", "Flowers"] sent to from the method which parses the dictionary to store the key route to the value, in this case "1".
Can someone please help me to build the dictionary which I would send to the jsonify method. Any help would be appreciated.
Hope this is what you are asking:
def build_dictionary(key_chain, j):
for k in key_chain:
j = j.get(k)
return j
kchain = ["app","Garden", "Flowers"]
>>> build_dictionary(kchain, j)
{'id': '1', 'state': 'fresh'}
