Adding new item to pymongo cursor
I am trying to add a new field to a json string (or to be more exact a bson string) so i can pass this onto the front end.
I have done a load of research, i have tried treating results like a dictionary, i tried adding the field to the database but still nothing.
@app.route('/')
@app.route('/index')
def index():
i=10
make = db.cars.distinct("Make")
model = db.cars.distinct("Short Model")
year = db.cars.distinct("Year introduced")
results = db.cars.find().limit(i)
print(results[0]['Make'])
x=0
while x < i:
print(x)
r = requests.get('https://izrite.com:5555/image/' + results[x]['Vehicle ID'])
r=r.json()
print(results[x])
results[x]['carImage'] = r['url']
print(results[x])
x=x+1
print("finished")
return render_template('index.html', title='Home', numresults=str(i), make=make, model=model, year=year, results=results)
existing string
{'_id': ObjectId('5c2bebbe7b94a040bce5eadf'), 'Vehicle ID': '74908', 'Make': 'MERCEDES-BENZ', 'Short Model': 'A CLASS', 'Long Model': 'A CLASS HATCHBACK', 'Trim': 'SE', 'Derivative': 'A160 SE 5dr Auto', 'Year introduced': '2016', 'Year discontinued': '', 'Currently Available': 'Y'}
desired string
{'_id': ObjectId('5c2bebbe7b94a040bce5eadf'), 'Vehicle ID': '74908', 'Make': 'MERCEDES-BENZ', 'Short Model': 'A CLASS', 'Long Model': 'A CLASS HATCHBACK', 'Trim': 'SE', 'Derivative': 'A160 SE 5dr Auto', 'Year introduced': '2016', 'Year discontinued': '', 'Currently Available': 'Y', 'carImage': 'http://images.capnetwork.co.uk/VehicleImage.aspx?SUBID=152231&HASHCODE=FE9015D10FEB72AE9042DB62DAC0ACFE&DB=car&CAPID=74908&VIEWPOINT=3'}
i would like within the json string to have a new field called carImage with the url in it, but i cant get this to work.

Where exactly are you looking at this string? Is it theprint(results[x])
?

yes both print(results[x]) are showing the same string.

What happens if you just printr['url']
without trying to add it toresults
? What happens if you omit the firstprint(results[x])
? What happens if you add some arbitrary fixed value (like the string'HELLO'
) toresults
, instead ofr['url']

- I think the reason why your changes are not reflecting, is because
you are trying to access the documents inside the cursor using an
index (like a list), but that doesn't seem to work. - In your last statement, you are trying to return the cursor object directly in the
render_template
function which is wrong. The cursor object is not a list (python list) of json documents as you are assuming.
The below code will work if you want to just see the changes being reflected.
@app.route('/')
@app.route('/index')
def index():
i=10
make = db.cars.distinct("Make")
model = db.cars.distinct("Short Model")
year = db.cars.distinct("Year introduced")
results = db.cars.find().limit(i)
#print(results[0]['Make'])
for doc in results:
r = requests.get('https://izrite.com:5555/image/' + results[x]['Vehicle ID'])
r=r.json()
print(doc)
doc['carImage'] = r['url']
print(doc)
print("finished")
# return render_template('index.html', title='Home', numresults=str(i), make=make, model=model, year=year, results=results)
If you want to update all documents and return, then convert result of find()
to a list as below. But, do note that, it will load all documents into the memory.
@app.route('/')
@app.route('/index')
def index():
i=10
make = db.cars.distinct("Make")
