Why isn't my json working? Do I need json to send a dictionary of data to my page?
Here is the code in question:
success: function(data) {
var new_data = $.parseJSON(data);
$('td#c00').html(new_data.img);
},
And
results = {'img':img, 'loc':match['number'][p]}
return HttpResponse(json.dumps(results))
I'm trying to send an img url and the number associated with it.
Eventually I want to be able to replace the 'td#c00' tag with one that changes based on the number I pass in through json.
This is how you do it:
var new_data = $.parseJSON(data);
$('td#c00').html(new_data['img']);

{ "PrcCfgDetails": [
{
"header_id": "10984299",
"line_id": "1143673632"
},
{
"header_id": "10984299",
"line_id": "1143673633"
}
]
}
I have above response file and I have written next 2 line of code in python. I do see above in response2 but don't know how to write a loop and get the value of header_id and line_id for number of records in response. Can you please help me in writing rest of the code.
response2 = requests.post(OAUTH_ENDPOINT, headers=headers_get, data=python2json)
user_data1 = json.dumps(response2.text)
user_data1 = response2.json()
Will return a dictionary of lists of dictionary. The top level will have one key -- PrcCfgDetails -- accessible with user_data1.get('ProCfgDetails')
I'm working in Python (3.8) and I've successfully called an API gotten it to print the JSON within command line after running the Python file. Now, I want to be able to print a particular list of information (like all of the names from the JSON), and later on save that list as its own set of data, but I'm hitting a block.
Example JSON I'm working with:
{
"data": {
"employees": [
{
"fields": {
"name": "Buddy",
"superheroName": "Syndrome",
"workEmail": "syndrome#example.com",
}
},
{
"fields": {
"name": "Helen Parr",
"superheroName": "Elastigirl",
"workEmail": "elastigirl#example.com",
}
}
]
}
I’ve tried the following so far and I was able to get “data” to print, but anytime I try to print another “layer” and get to say...“employees” or “fields” even, I hit a wall.
url = "my API url"
response = requests.get(url)
if response.status_code != 200:
print('Error with status code {}'.format(response.status_code))
exit()
jsonResponse = response.json()
jsonPretty = json.dumps(jsonResponse, indent=4, sort_keys=True)
jsonDictionary = json.loads(jsonPretty)
keys = jsonDictionary.keys()
for key in jsonDictionary.keys():
print(key)
Ideally, could someone share insight into how I can access the 'name' JSON value and get Python to print it as a list like the following, for example:
Buddy
Helen Parr
JSON files are basically nested dictionaries. jsonDictionary only contains one key and one entry under that key: data and another dictionary with the rest your result respectively.
If you wanted to access the name fields specifically:
employeesDict = jsonDictionary['data']
feildsDictList = employeesDict['employees']
firstFieldsDict = fieldsDictList[0]
secondFieldsDict = fieldsDictList[1]
firstName = firstFieldsDict['name']
secondNAme = secondFieldsDict['name']
You can access it like this (make sure it's already a dictionary):
for i in h['data']['employees']:
print(i['fields']['name'])
This way you can access the names with i['fields']['name']
I have a rather massive JSON objects and I'm trying to generate a specific JSON using only certain elements from it.
My current code looks like this:
data = get.req("/v2/users")
data = json.loads(data)
print (type(data)) # This returns <class 'list'>
print (data) # Below for what this returns
all_data = []
for d in data:
login_value = d['login']
if login_value.startswith('fe'):
continue
s = get.req("/v2/users/" + str(login_value)) # Sending another request with each
# login from the first request
all_data.append(s)
print (all_data) # Below for what this looks like this
print (data) before json.loads is str for the information, it returns data like this:
[
{
"id": 68663,
"login": "test1",
"url": "https://x.com/test"
},
{
"id": 67344,
"login": "test2",
"url": "https://x.com/test"
},
{
"id": 66095,
"login": "hi",
"url": "https://x.com/test"
}
]
print (all_data) returns a similar result to this for every user a request was sent for the first time
[b'{"id":68663,"email":"x#gmail.com","login":"xg","phone":"hidden","fullname":"xg gx","image_url":"https://imgur.com/random.png","mod":false,"points":5,"activity":0,"groups":['skill': 'archery']}
And this repeats for every user.
What I'm attempting to do is filtering by a few fields from all those results I received, so the final JSON I have will look something like this
[
{
"email": "x#gmail.com",
"fullname": "xg gf",
"points": 5,
"image_url", "https://imgur.com/random.pmg"
},
{
... similar json for the next user and so on
}
]
I feel as if the way I'm iterating over the data might be inefficient, so if you could guide me to a better way it would be wonderful.
In order for you to fetch login value, you have to iterate over data atleast once and for fetching details for every user, you have to make one call and that is exactly what you have done.
After you receive the user details instead of appending the whole object to the all_data list just take the field you need and construct a dict of it and then append it to all_data.
So your code has time complexity of O(n) which is best I understand.
Edit :
For each user you are receiving a byte response like below.
byte_response = [ b'{"id":68663,"email":"x#gmail.com","login":"xg","phone":"hidden","fullname":"xg gx","image_url":"https://imgur.com/random.png","mod":false,"points":5,"activity":0,"groups":[]}']
I'm not sure why would you get a response in a list [], but if it like that then take byte_response[0] so that we have the actual byte data like below.
byte_response = b'{"id":68663,"email":"x#gmail.com","login":"xg","phone":"hidden","fullname":"xg gx","image_url":"https://imgur.com/random.png","mod":false,"points":5,"activity":0,"groups":[]}'
response_decoded = byte_response.decode("utf-8") #decode it
import json
json_object_in_dict_form = json.loads(response_decoded) #convert it into dictionary
and then...
json_object_in_dict_form['take the field u want']
you can write:
data = get.req("/v2/users")
data = json.loads(data)
all_data = []
for d in data:
...
s = get.req("/v2/users/" + str(login_value))
new_data = {
'email': s['email'],
'fullname': s['fullname'],
'points': s['points'],
'image_url': s['image_url']
}
all_data.append(new_data)
print (all_data)
or you can make it fancy using an array with the fields you need:
data = get.req("/v2/users")
data = json.loads(data)
all_data = []
fields = ['email', 'fullname', 'point', 'image_url']
for d in data:
...
s = get.req("/v2/users/" + str(login_value))
new_data = dict()
for field in fields:
new_data[field] = s[field]
all_data.append(new_data)
print (all_data)
I have the following json object (Say car_details.json):
{
"name":"John",
"age":30,
"cars":
[
{
"car_model": "Mustang",
"car_brand": "Ford"
},
{
"car_model": "cx-5",
"car_brand": "Mazda"
}
}
I want to change the value of car_model from cx-5 to cx-9 through python code.
I am providing the json path to this element, through an external file. The json-path expression is basically represented as a string. Something like this:
'cars[2].car_model'
And the new value is also provided through an external file as a string:
'cx-9'
Now how do I parse through car_details.json using the jsonpath expression, and change its value to the one provided as string, and finally return the modified json object
P.S I want to do this through python code
This is an approach without using json module. Load your data in variable. Then iterate over cars key/values. If you find the key that is the value you are looking for set it to new value.
Also note: you need to close your array block, otherwise your above json is not valid. Generally I use an online json parser to check if my data is valid etc. (may be helpful in future).
data = {
"name":"John",
"age":30,
"cars":
[
{
"car_model": "Mustang",
"car_brand": "Ford"
},
{
"car_model": "cx-5",
"car_brand": "Mazda"
}
]
}
for cars in data['cars']:
for key, value in cars.items():
if key == "car_model" and value == "cx-5":
cars[key] = "cx-9"
print(data)
If you want to load your json object from a file, let's assume it is called "data.json" and is in the same directory as the python script you are going to run:
import json
with open('data.json') as json_data:
data = json.load(json_data)
for cars in data['cars']:
for key, value in cars.items():
if key == "car_model" and value == "cx-5":
cars[key] = "cx-9"
print(data)
Now if you'd like to write the content to the original file or new file, in this case I am writing to a file called "newdata.json":
import json
import re
with open('data.json') as json_data:
data = json.load(json_data)
print(data)
with open('external.txt') as f:
content = f.read()
print(content)
for cars in data['cars']:
for key, value in cars.items():
if key == "car_model" and value == "cx-5":
cars[key] = content
with open('newdata.json', 'w') as outfile:
json.dump(data, outfile)
I have a JSON data that I sent to my server using AJAX. The data comes here and I see it.
def add_collection(self):
form = AccountForm.LoginForm(request.form)
if self.request.method == 'GET' :
return render_template('add_collection.html',user=current_user,formLogin = form)
elif self.request.method == 'POST' :
for data in self.request.data :
print "The data is %s" %data
When I print self.request.data I get my JSON like
[{"image":"https://mybucket.s3.amazonaws.com/asma.jpg","Description":"Photo Descriptiong"},
{"image":"https://mybucket.s3.amazonaws.com/NCg3G.png","Description":"Photo Description"}]'
The above is exactly what my JSONfile looks like and what I am expecting. However, I want to break it into the two rows and insert into the database. Please how do i loop through JSON. I have seen similar questions here and many more. However, none works for me. When i tried
for data in self.request.data :
print data['image']
TypeError: string indices must be integers, not str
Please how do i achieve this ?Any help would be appreciated.
Below is my ajax request .
$.ajax({
url: "/user/add_collection",
type: 'POST',
contentType:'application/json',
data: JSON.stringify(arr),
dataType:'json',
success : function(data,status){
console.log("The image upload data returns", data);
console.log("the image upload status is", status);
},
error : function(xhr, ajaxOptions, thrownError){
//$.mobile.loading('hide');
if (xhr.status == 200) {
alert(ajaxOptions);
}
else {
alert(xhr.status);
alert(thrownError);
}
}
});
I am using python running flask framework .
I think you are getting the response as a string (self.request.data).
To treat it as objects, you need to convert it (from string to python representation) first:
elif self.request.method == 'POST' :
parsed_json = json.loads(self.request.data)
for data in parsed_json:
print data['image']
JSON data is received as a string. You need to parse it first.
data = json.loads(self.request.data)
