Uniswap Graph QL Wrong Price

I'm working on a DeFi price bot for python practice. I thought my code had been bugged, when it calculated the price of WETH to ADS.
After auditing my code and realizing it was calculating the correct way, I went further up in the chain and got that the data coming from Uniswap's Graph QL is actually where the error is. Here is the info being given to me by GraphQL, relating to the price of ADS/WETH
{
"id": "0xb9044f46dcdea7ecebbd918a9659ba8239bd9f37",
"totalValueLockedETH": "9904.271380202576136314291146113488",
"token0Price": "0.001320257312519524061776624436378727",
"token1Price": "757.4281092915453379114232503540107",
"feeTier": "10000",
"token0": {
"id": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",
"symbol": "WETH",
"name": "Wrapped Ether",
"decimals": "18"
},
"token1": {
"id": "0xcfcecfe2bd2fed07a9145222e8a7ad9cf1ccd22a",
"symbol": "ADS",
"name": "Adshares",
"decimals": "11"
}
},
As you can see in token0Price, we are being given "0.0013..." for the price.
However, manually selecting ADS -> WETH in Uniswap's dapp, gives the price: "0.00078".
Am I using GraphQL wrong? Or is this an issue on the Uniswap side?

How to get the value from particular key using python?

resp = {
"Name": "test",
"os": "windows",
"Agent": {
"id": "2",
"status": [
{
"code": "123",
"level": "Info",
"displayStatus": "Ready",
"message": "running",
"time": "2022-01-18T09:51:08+00:00"
}
]
}
I am trying to get the time value from the JSON.
I tried the below code but faced error with dict
resp1 = json.loads(resp)
resp2 = resp1.values()
creation_time = resp2.get("Agent").get("status")
val= creation_time["time"]
print(val) ## Thrwoing error as dict_values has no 'get'
Any suggestion on python how to take this time values

Few problems I noticed
You are trying to load a Dict type using the json's loads function which is supposed to get a string in json format (ex: '{ "name":"John", "age":30, "city":"New York"}')
You tried to access resp2 before declaration (I guessed you meant "resp1?")
You're using resp3 without declaration.
You are missing }
You don't need the .value() function because it will return a list.
Also creation time is a list with one object, so you need to access it too.
Considering all this, you can change it as follows:
import json
resp = '{ "Name": "test", "os": "windows","Agent": {"id": "2","status": [{"code": "123","level": "Info","displayStatus": "Ready","message": "running","time": "2022-01-18T09:51:08+00:00"}]}}'
resp1 = json.loads(resp)
creation_time = resp1.get("Agent").get("status")
val= creation_time[0]["time"]
print(val)

You just need to access the dicts using [] like so:
resp = {"Name": "test", "os": "windows", "Agent": {"id": "2","status": [{"code": "123","level": "Info","displayStatus": "Ready","message": "running","time": "2022-01-18T09:51:08+00:00"}]}}
creation_time = resp["Agent"]["status"]
val= creation_time[0]["time"]
print(val)
Output:
2022-01-18T09:51:08+00:00

Flask-restplus returning marshal model instead of the data

So I'm pretty new to implementing flask-restplus and I have encountered this road block.
I have read the restplus docs over and over again and followed several exampled. But the behavior that I'm facing is very much different from what is supposed to be.
So I have a model that is supposed to be a list of objects of another model (returned from the function drone_model()).
drones_list = api.model('drones_list', {
'items': fields.List(fields.Nested(drone_model())),
'message':fields.String(''),
'code': fields.Integer('')
})
Everything works fine, no errors. But when I try the API (http://127.0.0.1:5000/datamine/v2/drones), as a response I get the Marshalling model back instead of the data itself. If I print the data, it gets printed, but for some reason in the web, the restplus model is returned.
Below I have the code that I had written. If I take the marshal_with decorator off, then the data is returned just fine.
#api.route('/')
class DronesList(Resource):
#api.marshal_with(drones_list, envelope='data')
#api.response(200, 'All drones successfully fetched!')
def get(self):
"""
Get all drones!.
"""
from app.utils.common import get_start_end_date_from_request
start_date, end_date = get_start_end_date_from_request(request)
drones = []
for drone in Drone.objects:
drones.append({
'id': str(drone.id),
'serial_id': drone.serial_id,
'maintenances': [],
'status': get_dynamic_status(drone, start_date, end_date),
'picture_url': drone.asset.picture_url,
'manufacturer': drone.asset.manufacturer,
'model_name': drone.asset.model_name,
'drone_type': drone.asset.drone_type,
'payload_type': drone.asset.payload_type,
'asset_url': drone.get_url(drone.id)
})
success = ClientSuccessFunctionClass('All drones successfully fetched!', 200, drones)
return (success.to_dict())
These are the outputs on the browser:
1. Without the marshal decorator:
{
"data": {
"items": [
{
"id": "5aeafcb93a33683f73827e91",
"serial_id": "Drone 1",
"maintenances": [],
"status": "Decommissioned",
"picture_url": "some img url",
"manufacturer": "DJI",
"model_name": "Phantom 4 Pro",
"drone_type": "Quadcopter",
"payload_type": "RGB Camera",
"asset_url": "http://127.0.0.1:5000/datamine/v1/drones/5aeafcb93a33683f73827e91"
},
{
"id": "5aeaff374f85747f90df2714",
"serial_id": "Drone 2",
"maintenances": [],
"status": "Available",
"picture_url": "sime url",
"manufacturer": "DJI",
"model_name": "Phantom 4",
"drone_type": "Quadcopter",
"payload_type": "RGB Camera",
"asset_url": "http://127.0.0.1:5000/datamine/v1/drones/5aeaff374f85747f90df2714"
}
],
"message": "All drones successfully fetched!",
"code":200
}
}
2. With the marshal decorator:
{
"data": {
"items": [
{
"id": "Id of Drone",
"serial_id": "Name of Drone",
"status": "Status of Drone",
"maintenances": null,
"picture_url": "Picture URL",
"manufacturer": "Manufacturer of Drone",
"model_name": "Model name of Drone",
"drone_type": "Type of Drone",
"payload_type": "Payload type of Drone",
"asset_url": "Asset URL of Drone"
}
],
"message": "",
"code": ""
}
}
It would be really helpful if someone could tell me what I'm doing wrong as I need to recive the output as the one shown in snippet of the output without the decorator.
Thank you.

Here is a diagram showing invocation order from top to bottom to help make sense of what is happening:
get()
→ api.response(200, 'All drones successfully fetched!') # documents the response
→ api.marshal_with(drones_list, envelope='data')` # returns marshalled dict
The result from invoking get is passed to the api.response decorator function whose result is passed on to api.marshal_with decorator function.
Looking at the shape of the dictionary returned from invoking get()
{
data {
items [
{
id,
serial_id,
maintenances,
status,
picture_url,
manufacturer,
model_name,
drone_type,
payload_type,
asset_url
}
],
message,
code
}
}
The message and code in the response are nested inside of the data.
You need to model the data appropriately, to be able to marshal it. This can be done by passing an argument for what field to look up in the marshal dictionary.
drones_list = api.model('drones_list', {
'items': fields.List(fields.Nested(drone_model()), attribute='data.items'),
'message':fields.String(attribute='data.message'),
'code': fields.Integer(attribute='data.code')
})
As you can see, it's pretty redundant applying the api.marshal_with decorator function on the view given that it's only unnests then nests the result in data field.

Accessing nested objects with python

I have a response that I receive from foursquare in the form of json. I have tried to access the certain parts of the object but have had no success. How would I access say the address of the object? Here is my code that I have tried.
url = 'https://api.foursquare.com/v2/venues/explore'
params = dict(client_id=foursquare_client_id,
client_secret=foursquare_client_secret,
v='20170801', ll=''+lat+','+long+'',
query=mealType, limit=100)
resp = requests.get(url=url, params=params)
data = json.loads(resp.text)
msg = '{} {}'.format("Restaurant Address: ",
data['response']['groups'][0]['items'][0]['venue']['location']['address'])
print(msg)
Here is an example of json response:
"items": [
{
"reasons": {
"count": 0,
"items": [
{
"summary": "This spot is popular",
"type": "general",
"reasonName": "globalInteractionReason"
}
]
},
"venue": {
"id": "412d2800f964a520df0c1fe3",
"name": "Central Park",
"contact": {
"phone": "2123106600",
"formattedPhone": "(212) 310-6600",
"twitter": "centralparknyc",
"instagram": "centralparknyc",
"facebook": "37965424481",
"facebookUsername": "centralparknyc",
"facebookName": "Central Park"
},
"location": {
"address": "59th St to 110th St",
"crossStreet": "5th Ave to Central Park West",
"lat": 40.78408342593807,
"lng": -73.96485328674316,
"labeledLatLngs": [
{
"label": "display",
"lat": 40.78408342593807,
"lng": -73.96485328674316
}
],
the full response can be found here

Like so
addrs=data['items'][2]['location']['address']

Your code (at least as far as loading and accessing the object) looks correct to me. I loaded the json from a file (since I don't have your foursquare id) and it worked fine. You are correctly using object/dictionary keys and array positions to navigate to what you want. However, you mispelled "address" in the line where you drill down to the data. Adding the missing 'a' made it work. I'm also correcting the typo in the URL you posted.
I answered this assuming that the example JSON you linked to is what is stored in data. If that isn't the case, a relatively easy way to see exact what python has stored in data is to import pprint and use it like so: pprint.pprint(data).
You could also start an interactive python shell by running the program with the -i switch and examine the variable yourself.

data["items"][2]["location"]["address"]
This will access the address for you.

You can go to any level of nesting by using integer index in case of an array and string index in case of a dict.
Like in your case items is an array
#items[int index]
items[0]
Now items[0] is a dictionary so we access by string indexes
item[0]['location']
Now again its an object s we use string index
item[0]['location']['address]

Python Falcon filtering through URL

I have a small API that i'm working on, everything works ok, all my requests do what they are supposed to but when I try to filter results through the URL query for some reason it works for id but not for device field.
def on_get(self, req, resp):
"""Handles GET requests"""
if req.get_param("id"):
result = {'location': r.db(PROJECT_DB).table(PROJECT_TABLE).get(req.get_param("id")).run(db_connection)}
elif req.get_param("device"):
result = {'location': r.db(PROJECT_DB).table(PROJECT_TABLE).get(req.get_param("device")).run(db_connection)}
else:
location = r.db(PROJECT_DB).table(PROJECT_TABLE).run(db_connection)
result = {'locations': [i for i in location]}
resp.body = json.dumps(result)
example http://localhost:8000/location?id=(some random id) this will work
but if i do http://localhost:8000/location?device=(some device) this will not work, returns null
So could anyone tell me what am I doing wrong? or better yet if anyone knows a better way to filter using the URL?
Note: I am using rethinkdb
EDIT:
This is what I have normally:
{
"locations": [
{
"id": "4bf4b94f-747a-42db-9d54-a8399d995025",
"location": "gps coords",
"device": "Device 2"
},
{
"id": "b5cce561-37d2-42e7-86e4-a31c008b0af2",
"location": "gps coords",
"device": "Device 1"
},
{
"id": "bebba7cf-710c-4ee8-ad69-2d58174d4e02",
"location": "gps coords",
"device": "Device 1"
},
{
"id": "e928f84b-60ff-40f3-b839-920bc99e5480",
"location": "gps coords",
"device": "Device1"
}
]
}
Filtering by id works ok, but not by device which is weird

I found the answer to this problem, the reason why it did not war was because rethinkdb only gets via primary key on the get query
result = {'location': r.db(PROJECT_DB).table(PROJECT_TABLE).get(req.get_param("device")).run(db_connection)}
so what I should have done was to filter the results by what I wanted like this and it would have worked
result = {'location': list(r.db(PROJECT_DB).table(PROJECT_TABLE).filter({'device': param}).run(db_connection))}
Thanks for the help everyone and hope this answer helps.
