How can I access Json attribute and check if (key)exist in payload or not using python

This is my UI
End user can able to update Summary or my_story one at a time, This is my endpoint URL http:localhost:3000/api/account/profile, once user update any one of the field, the URL will work
This is Request payload for summary field
If the user update the Summary field the above endpoint URL will work.
This is Request payload for my_story field
If the user update the my_story field the above endpoint URL will work.
My code(Once the user update anyone of the field. I want to check which field is updated, for this how can I check whether the user is updated Summary or my_story,after accessing the field I want to sanitize the field and send it to response below one is my code):
from lxml.html import clean
def account_update():
data = json.loads(request.data)
cleaner = clean.Cleaner()
if data['other_details']['summary']:
clean_overview = (data['other_details']['summary'])
sanitized_html = cleaner.clean_html(clean_overview)
else:
clean_overview = (data['other_details']['my_story'])
sanitized_html = cleaner.clean_html(clean_overview)
return jsonify({"account": data})
Guys , in the above code I am getting the request payload as data, after that I am accessing the summary and my_story fields as data['other_details']['summary'] and data['other_details']['summary'], here I wrote if condition to check if the user update summary field if condition will work suppose user update my_story field it will goes to else part, but in my case if I update my_story field getting error.
Error:
if data['other_details']['summary']:
KeyError: 'summary'
NOTE:
Sanitizing the field is working fine (I mean cleaner = clean.Cleaner() and sanitized_html = cleaner.clean_html(clean_overview), I just want to know which field the user is updating. Please help me guys.

Most likely, the request.data doesn't always have the summary field in data['other_details'].
This means, you have to check for it in you if-else block before trying to access it.
Best to check for other_details as well.
Here is one way of doing this:
from lxml.html import clean
def account_update():
data = json.loads(request.data)
cleaner = clean.Cleaner()
if 'other_details' in data:
other_details = data['other_details']
if 'summary' in other_details:
clean_overview = other_details['summary']
sanitized_html = cleaner.clean_html(clean_overview)
elif 'my_story' in other_details:
clean_overview = other_details['my_story']
sanitized_html = cleaner.clean_html(clean_overview)
return jsonify({"account": data})

What i see your program just can't find summary atribute.
Solution 1
Im not sure this will work but function getattr() can help you.
Change this line
data['other_details']['summary']
To this
getattr(getattr(data,'other_details'),'summary', False)
Here you can learn more about getattr()
What is getattr() exactly and how do I use it?
Solution 2
Just use some try: and except:

Django HTTP request to api

So i been trying to get this to work but at the same time i do not understand some of these code means. I'm sorry for making the question so long but i want to understand how these works.
I am trying to make a HTTP request to another API to do POST and GET method using django. Based on the website code example, which is this url: https://www.twilio.com/blog/2014/11/build-your-own-pokedex-with-django-mms-and-pokeapi.html
As i wanted to use HTTP Request on my API to call other API, therefore i wanted to get a better understanding of how these works and how to use it.
The code is at the bottom of the website. But i will just provide the code here so it is easier for you.
website code
from django_twilio.views import twilio_view
from twilio.twiml import Response
import requests
import json
BASE_URL = 'http://pokeapi.co'
def query_pokeapi(resource_uri):
url = '{0}{1}'.format(BASE_URL, resource_uri)
response = requests.get(url)
if response.status_code == 200:
return json.loads(response.text)
return None
#twilio_view
def incoming_message(request):
twiml = Response()
body = request.POST.get('Body', '')
body = body.lower()
pokemon_url = '/api/v1/pokemon/{0}/'.format(body)
pokemon = query_pokeapi(pokemon_url)
if pokemon:
sprite_uri = pokemon['sprites'][0]['resource_uri']
description_uri = pokemon['descriptions'][0]['resource_uri']
sprite = query_pokeapi(sprite_uri)
description = query_pokeapi(description_uri)
message = '{0}, {1}'.format(pokemon['name'], description['description'])
image = '{0}{1}'.format(BASE_URL, sprite['image'])
frm = request.POST.get('From', '')
if '+44' in frm:
twiml.message('{0} {1}'.format(message, image))
return twiml
twiml.message(message).media(image)
return twiml
twiml.message("Something went wrong! Try 'Pikachu' or 'Rotom'")
return twiml
My question is:
i have read about the request.POST and request.POST.get but i still don't get it. Isn't request.POST = POST method/create function ?
what does body.lower mean ? Cant seems to find anything about it.
I am very confuse about this part
sprite_uri = pokemon['sprites'][0]['resource_uri']
description_uri = pokemon['descriptions'][0]['resource_uri']
sprite = query_pokeapi(sprite_uri)
description = query_pokeapi(description_uri)
is pokemon['sprites'] refers to the sprites field in the api ?
What does this even means ?
frm = request.POST.get('From', '')
if '+44' in frm:
twiml.message('{0} {1}'.format(message, image))
return twiml
twiml.message(message).media(image)
return twiml
request.POST.get('From', '') Isn't POST where user enter data ? Where does 'From' come from? And what does this means ? if '+44' in frm: if +44 is found in frm ?

ALL The questions are based on very basic python concepts, I recommend you go through python docs here Python Docs
Diff in request.POST and request.POST.get()
Ex request.post has following dict {'abc_key': 'abc_value'}
than request.POST['abc_key'] will give 'abc_value'
but request.POST['xyz_key'] will throw error
so we use default value to escape this error
request.POST.get('xyz_key', "default_value")
this will not give error if xyz_key is not found
body.lower
This method returns a copy of the string in which all case-based
characters have been lowercased.
check this link lower()
pokemon['sprites'][0]['resource_uri']
this is serching in pokemon (which have dictionary values)
Ex. pokemon = {'sprites':[{'resource_uri': 'res_value'}, 1, 2, 3 ]}
so pokemon['sprites'][0]['resource_uri'] will give 'res_value'
frm = request.POST.get('From', '') same as i said in 1st point
if '+44' in frm:
this will return True if string '+44' is substring in frm
variable(string)

Robobrowser and flask errors

I am trying to create a script for myself to use on a few classified sites and starting with cl, I am using flask web framework and robobrowser but not going so well.
The Goal It will take my preset values and put them in the fields from that classifieds websites. Doesnt seem like a difficult concept however after 5 hours of reading online different code and trial and error I remembered the best developers are on stack...
I should inform you I am new to Python and still have alot to learn so any help would be greatly appreciated.
The error I get is:
assert isinstance(form, 'str')
TypeError: isinstance() arg 2 must be a type or tuple of types
but I dont see how to fix this and completely lost. HELP!!!
thanks in advance
# autosubmit to site
from flask import Flask
from robobrowser import RoboBrowser
app = Flask(__name__)
#app.route('/', methods = ['GET', 'POST'])
class My_RoboBrowser(RoboBrowser):
def __init__(self, auth=None, parser=None, headers=None, user_agent=None, history=True):
RoboBrowser.__init__(self, parser=None, user_agent=None, history=True)
def Open(self, vURL, vVerify=True):
response = self.session.get(vURL, verify=vVerify)
self._update_state(response)
browser = My_RoboBrowser(RoboBrowser, "html.parser");
urlL = 'https://accounts.craigslist.org/login'
browser.Open(urlL)
form = browser.get_form(id='login')
assert isinstance(form, 'str')
form['username'] = 'username'
form['password'] = 'password'
browser.submit_form(form)
urlQ = 'https://post.craigslist.org/k/qGDv7K4q5RGD0B5ZEBgXOQ/GLzgd?s=edit'
browser.open(urlQ)
#Question_Tag = browser.find_all(class_="not_answered")[0]
#ID = Question_Tag.get('data-qid')
#Get the form to fill out
Form = browser.get_form(id='formpost')
Form['PostingTitle'].value = 'Create this advertise ment in py'
Form['Postal_code'].value = ['10543']
Form['PostingBody'].value = 'TOGETHER WE INNOVATE Stress free communication with developers that are in the United States. We pride ourselves in bringing your web and app ideas to life and keeping your data secured'
browser.submit_form(Form)
if __name__ == "__main__":
app.run()

isinstance returns true if the first argument is an instance (or subclass) of the second argument otherwise false. In your assertion the form variable is of type robobrowser.forms.form.Form. You can see this with the following code:
print(type(form)) # should print <class 'robobrowser.forms.form.Form'>
Your particular assertion will pass if you update the second argument to indicate this robobrowser Form class:
# Add the following to your imports
import robobrowser
# ... existing code below imports
# The following should be true if form is valid
assert isinstance(form, robobrowser.forms.form.Form)
You can also import the Form class directly but you'll have to update the assertion accordingly:
from robobrowser.forms.form import Form
# ... existing code below imports
assert isinstance(form, Form)
Edit:
Below is the code to properly get the form from that page. There are no forms with an id of 'login' but you can select it by using its action or grabbing the first form on the page.
# ... previous code ...
form = browser.get_form(action='https://accounts.craigslist.org/login')
# you can also use: form = browser.get_form(0)
# It looks like you aren't selecting the fields by their proper names either.
form['inputEmailHandle'] = 'fill in username here'
form['inputPassword'] = 'fill in password here'
browser.submit_form(form)
See if the added code above helps.

Django AngularJS JSONResponse view in rendering json output

i am developing one of my site with the python django where i have been using angularjs in one of my page where i have given the user option to search (specific request). Here is my model..
class Request(models.Model):
description = models.TextField(blank=True,null=True)
category = models.ForeignKey(Category)
sub_category = models.ForeignKey(SubCategory)
In my views I am returning through the following code:
def some(code, x):
exec code
return x
def search_request(request):
page = request.GET.get('page')
term = request.GET.get('term')
i = 0
terms = "x = Request.objects.filter("
for t in term.split(" "):
i=i+1
if(len(term.split(" "))>i):
terms = terms +"Q(name__icontains='"+t+"')|"
else:
terms = terms +"Q(name__icontains='"+t+"'))"
junk = compile(terms,'<string>', 'exec')
spit = Request.objects.filter(name__icontains=term)
requests = some(junk,spit)
output = HttpResponse()
output['values']=[{'requests':r,'category':r.category,'subcategory':r.sub_category} for r in requests]
return JSONResponse(output['values'])
In my HTML code when I return using AngularJS:
$scope.search = function(){
$scope.results = $http.get("{% url 'search-requests-show' %}?term="+$scope.term).then(
function(result){
return result.data;
}
);
}
The result on the HTML Output comes as in {[{results}]}:
"[{'category': <Category: The New Category>, 'requests': <Request: Need a Table>, 'subcategory': <SubCategory: Testsdfsdfsad>}]"
The problem is that I am not being able to access using results.category because the output is in "string", so the ng-repeat="result in results" brings the result as
[ { ' c a .....
I am probably doing something wrong in view. If anybody has any suggestion then please answer.

JSONResponse is probably using standard python json encoder, which doesn't really encode the object for you, instead it outputs a string representation (repr) of it, hence the <Category: The New Category> output.
You might need to use some external serializer class to handle django objects, like:
http://web.archive.org/web/20120414135953/http://www.traddicts.org/webdevelopment/flexible-and-simple-json-serialization-for-django
If not, you should then normalize object into simple python types inside the view (dict, list, string.., the kind that json module has no problem encoding). So instead doing:
'category':r.category
you could do:
'category': {'name': r.category.name}
Also as a sidenote: using exec is super bad idea. Don't use it in production!

You should return json strings for Angular:
import json
def resource_view(request):
# something to do here
return HttpResponse(json.dumps(your_dictionary))
for better usage i recommend djangorestframework.
Off Topic:
$http.get("{% url 'search-requests-show' %}?term="+$scope.term);
you can pass 'param' object:
$http.get("{% url 'search-requests-show' %}", {param : {term:$scope.term}});

Django Query doesn't match

I have the following Django Model:
class State(models.Model):
name = models.CharField(max_length=80,null=False)
latitude = models.CharField(max_length=80,null=False)
longitude = models.CharField(max_length=80,null=False)
def __unicode__(self):
return self.name
In my views.py file I've created the following method:
def getCoords(request):
if request.is_ajax():
if request.method == 'POST':
try:
state = request.POST['state'] #receives the state from JS
stateInstance = State.objects.get(name=state)
stateLat = stateInstance.latitude
stateLong = stateInstance.longitude
data = {"lat" : stateLat, "long" : stateLong}
except State.DoesNotExist:
return HttpResponse("No record")
return HttpResponse(simplejson.dumps(data)) #returns json
So I'm sending this method a param through ajax, let's say "California". The state variable gets the value (I have proved that) but the query doesn't get executed, it returns the query doesn't match message. I've tried with the following as well:
state = request.POST['state']
if state == 'California':
return HttpResponse("Yes!")
else:
return HttpResponse(state)
When this snippet returns the state it displays California which means state's value is correct but the query is not executed properly. I don't know what's going on. Any thoughts?

Make sure you're connecting to the correct database in your settings.py. Make sure the record actually does exist with plain old SQL.
SELECT * FROM [app_name]_state WHERE name = 'California';
Also, try it from the Django shell. python manage.py shell
>>> from [app_name].models import State
>>> s = State.objects.get(name='California')
>>> s
<State: California>
Make sure that what is actually being sent is sent as POST, and not accidentally a GET variable in the URL. Also, make sure that the post variable has no extra characters and that it is actually valid. A decent way to do that is to just print it to the console, or if AJAX, with Firebug.
# Single quotes added so you can see any extra spaces in the console
print "'%s'" % state
