I just want to iterate through the list of JSON data which I get in the payload but getting an error as list indices must be integers or slices, not dict
payload:
[{"AuditorId":10,"Agents":"sa","Supervisor":"sa","TicketId":"58742","QId":150,"Answer":"Yes","TypeSelected":"CMT Mails","Comments":"na","TicketType":"Regularticket","Action":"na","AuditSubFunction":"na","AuditRegion":"na"},{"AuditorId":10,"Agents":"sa","Supervisor":"sa","TicketId":"58742","QId":151,"Answer":"Yes","TypeSelected":"CMT Mails","Comments":"na","TicketType":"Regularticket","Action":"na","AuditSubFunction":"na","AuditRegion":"na"}]
views.py:
#api_view(['POST'])
def SaveUserResponse(request):
for ran in request.data:
auditorid = request.data[ran].get('AuditorId')
ticketid = request.data[ran].get('TicketId')
qid = request.data[ran].get('QId')
answer = request.data[ran].get('Answer')
sid = '0'
TicketType = request.data[ran].get('TicketType')
TypeSelected = request.data[ran].get('TypeSelected')
agents = request.data[ran].get('Agents')
supervisor = request.data[ran].get('Supervisor')
Comments = request.data[ran].get('Comments')
action = request.data[ran].get('Action')
subfunction = request.data[ran].get('AuditSubFunction')
region = request.data[ran].get('AuditRegion')
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[sp_SaveAuditResponse] #auditorid=%s,#ticketid=%s,#qid=%s,#answer=%s,#sid=%s,#TicketType=%s,#TypeSelected=%s,#agents=%s, #supervisor =%s, #Comments=%s, #action=%s, #subfunction=%s, #region=%s',
(auditorid,ticketid,qid,answer, sid,TicketType, TypeSelected, agents, supervisor, Comments, action, subfunction,region))
return Response(True)
I ran this code on my machine and it works for the payload you provided.
#api_view(['POST'])
def SaveUserResponse(request):
for ran in request.data:
auditorid = ran.get('AuditorId')
ticketid = ran.get('TicketId')
qid = ran.get('QId')
answer = ran.get('Answer')
sid = '0'
TicketType = ran.get('TicketType')
TypeSelected = ran.get('TypeSelected')
agents = ran.get('Agents')
supervisor = ran.get('Supervisor')
Comments = ran.get('Comments')
action = ran.get('Action')
subfunction = ran.get('AuditSubFunction')
region = ran.get('AuditRegion')
If it doesn't then content of request.data must be different then payload you shared in original post

I'm a total beginner with Python/Django and trying to understand why this isn't working. I have a function that contains a for loop, doing some logic and then updating a model. but when I have more than 1 item in the loop I get a UNIQUE constraint failed: app_token.token_name error.
So I think I'm misunderstanding how the loop is working?
function
tokens = Token.objects.all()
for item in tokens:
if item.token_contract_address is not None:
token = Token.objects.get(pk=item.id)
parameters = {
'address':token.token_contract_address
}
session = Session()
session.headers.update(headers)
response = session.get(url, params=parameters)
resp = json.loads(response.text)
token_id = (resp['data'][next(iter(resp['data']))]['id'])
logo = (resp['data'][next(iter(resp['data']))]['logo'])
url = 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest'
parameters = {
'id':token_id
}
session = Session()
session.headers.update(headers)
response = session.get(url, params=parameters)
id = str(token_id)
price = (json.loads(response.text)['data'][id]['quote']['USD']['price'])
market_cap = (json.loads(response.text)['data'][id]['quote']['USD']['market_cap'])
change = (json.loads(response.text)['data'][id]['quote']['USD']['percent_change_24h'])
r = Token.objects.update(token_capture_date = formatedDate, token_price = price, token_name=item.token_name )
I'm expecting the this Token.objects.update(token_capture_date = formatedDate, token_price = price, token_name=item.token_name ) to update the model based on the item loop?
The model is very simple:
class Token(models.Model):
token_name = models.CharField(max_length=50, blank=False, unique=True)
token_slug = models.CharField(max_length=50, blank=True,null=True)
token_price = models.FloatField(blank=True,null=True)
token_capture_date = models.DateField(blank=True,null=True)
token_contract_address = models.CharField(max_length=50, blank=True,null=True)
def __str__(self):
return str(self.token_name)
I'm using the update on the objects and have tried removing the token_name, and tried using token.token_name
If I remove token_name= it updates both items in the database with the same values? which makes me think its this line r = Token.objects.update(token_capture_date = formatedDate, token_price = price, token_name=item.token_name ) do i need to apply some kinda of filter?
Thanks
I believe that by calling Token.objects.update() you actually end up trying to update all Token objects. Since token_name has to be unique, and you are giving it the same name as another Token object it throws that error.
Since you are already in a for loop, you can simply update the token that is currently being processed.
My suggestion would be to use this code instead:
item.token_capture_date = formattedDate
item.token_price = price
item.save()
This will make it so that the current token object which is being processed in the for loop has its respective field values updated and saved in the database.
Also, this line is unnecessary: token = Token.objects.get(pk=item.id) as we already have access to the token through the looping variable item.
Do let me know if this helps!
My model is as follows
class Drawing(models.Model):
drawingJSONText = models.TextField(null=True)
project = models.CharField(max_length=250)
Sample data saved in drawingJSONText field is as below
{"points":[{"x":109,"y":286,"r":1,"color":"black"},{"x":108,"y":285,"r":1,"color":"black"},{"x":106,"y":282,"r":1,"color":"black"},{"x":103,"y":276,"r":1,"color":"black"},],"lines":[{"x1":109,"y1":286,"x2":108,"y2":285,"strokeWidth":"2","strokeColor":"black"},{"x1":108,"y1":285,"x2":106,"y2":282,"strokeWidth":"2","strokeColor":"black"},{"x1":106,"y1":282,"x2":103,"y2":276,"strokeWidth":"2","strokeColor":"black"}]}
I am trying to write a view file where the data is filtered based on project field and all the resulting queryset of drawingJSONText field are made into one data
def load(request):
""" Function to load the drawing with drawingID if it exists."""
try:
filterdata = Drawing.objects.filter(project=1)
ids = filterdata.values_list('pk', flat=True)
length = len(ids)
print(list[ids])
print(len(list(ids)))
drawingJSONData = dict()
drawingJSONData = {'points': [], 'lines': []}
for val in ids:
if length >= 0:
continue
drawingJSONData1 = json.loads(Drawing.objects.get(id=ids[val]).drawingJSONText)
drawingJSONData["points"] = drawingJSONData1["points"] + drawingJSONData["points"]
drawingJSONData["lines"] = drawingJSONData1["lines"] + drawingJSONData["lines"]
length -= 1
#print(drawingJSONData)
drawingJSONData = json.dumps(drawingJSONData)
context = {
"loadIntoJavascript": True,
"JSONData": drawingJSONData
}
# Editing response headers and returning the same
response = modifiedResponseHeaders(render(request, 'MainCanvas/index.html', context))
return response
I runs without error but it shows a blank screen
i dont think the for function is working
any suggestions on how to rectify
I think you may want
for id_val in ids:
drawingJSONData1 = json.loads(Drawing.objects.get(id=id_val).drawingJSONText)
drawingJSONData["points"] = drawingJSONData1["points"] + drawingJSONData["points"]
drawingJSONData["lines"] = drawingJSONData1["lines"] + drawingJSONData["lines"]
i had built django server to handle some work.And when i sent 10000 requests to django,django will became slow after 4000th requests,it will report socket timeout randomly.And i take this one data to test it alone,it is ok.So,how can i fix this bug?
i have no idea to fix it
def handle(request) :
sys.stderr.write( "[info]request come in {} \n".format(sys._getframe().f_code.co_name))
ret_dict = dict()
ret_str = ""
if ("vid" in request.GET) and ("title" in request.GET):
id = request.GET["id"]
title = urllib.parse.unquote(request.GET["title"],encoding ='utf-8')
title = request.GET["title"]
req_video = dict()
req_video["vid"] = vid
req_video["title"] = title
tags = handle_function(req_video)
ret_dict["vid"] = vid
ret_dict["tags"] = tags
ret_str = json.dumps(ret_dict)
return HttpResponse(ret_str)
client codes:
for line in sys.stdin:
line = line.rstrip('\n')
fields = line.split("\t")
vid = fields[0]
title = fields[1]
page_params_mq = {'vid':vid,'title':title}
try :
rec_mq_res = get_rec_mingqiang(server_ip_mq, server_port_mq, web_page_mq, page_params_mq)
except:
print (line)
continue
vid = rec_mq_res["vid"]
tags = rec_mq_res["tags"]
fo.write(vid+"\t"+tags+"\n")
cat test_data|python client.py, there are 10000 rows in test_data,and it send request sequentially,and will be hunt randomly after 4000.
django can handle these requests quickly
I have a form where i am entering four details 'Persona Name', 'Persona Key' ,'Persona Key Label' and 'Persona Key Value' and on entering these values i am pressing Submit button which generates a GET request on my server.
Following are django views:-
def PersonaSave(request):
persona_name = request.GET.get('persona_name',)
persona_key = request.GET.get('key_name',)
persona_key_value = request.GET.get('key_value',)
persona_key_label = request.GET.get('key_label',)
persona_submit = request.GET.get('Save',)
return( persona_name , persona_key , persona_key_label , persona_key_value , persona_submit )
def TestPageView(request):
x=PersonaSave(request)
persona_name = x[0]
persona_key = x[1]
persona_key_label=x[2]
persona_key_value=x[3]
persona_submit=x[4]
if(persona_name is None and persona_key is None and persona_key_label is None and persona_key_value is None):
return render(request, 'dashboard/test_page.html')
elif TestPersonaName.objects.filter(name=persona_name).exists():
t= TestPersonaName.objects.get(pk=persona_name)
testpersona = TestPersona.objects.get(name=t)
if testpersona.key == persona_key:
testpersona.label= persona_key_label
testpersona.value = persona_key_value
t=TestPersonaName(name=persona_name)
t.save()
testpersona = TestPersona(name=t,key=persona_key,label=persona_key_label,value=persona_key_value)
testpersona.save()
return render(request,'dashboard/test_page.html')
I am rewriting codes of lines where updation and new persona formation starts to maintain the clarity of question.
Update Function starts from here-----
elif TestPersonaName.objects.filter(name=persona_name).exists():
t= TestPersonaName.objects.get(pk=persona_name)
testpersona = TestPersona.objects.get(name=t)
if testpersona.key == persona_key:
testpersona.label= persona_key_label
testpersona.value = persona_key_value
-----This is where update function ends
If persona name is different then complete new TestPersonaName object and TestPersona object will be formed.
For this the function starts here----
t=TestPersonaName(name=persona_name)
t.save()
testpersona = TestPersona(name=t,key=persona_key,label=persona_key_label,value=persona_key_value)
testpersona.save()
----and ends here.
Now the problem is for the same persona name and same persona key two different TestPersona objects are being formed. For e.g If I enter persona_name = Ankit,
key = 'city' and value = 'New Delhi' and later i want to change city so i enter
name='Ankit' , key = 'city' and name = 'Lucknow'. On pressing submit two different TestPersona objects are being formed. i.e
object1(name='Ankit',key='city', value='New Delhi') and
object2(name='Ankit',key='city',value='Lucknow')
Ideally it should be:-
object1(name='Ankit', key='city', value='Lucknow')
Following are TestPersonaName and TestPersona models:-
class TestPersonaName(models.Model):
name = models.CharField(max_length=100,primary_key=True)
class TestPersona(models.Model):
name = models.ForeignKey('TestPersonaName',on_delete=models.CASCADE)
key = models.CharField(max_length=200)
label = models.CharField(max_length=200,null=True,blank=True)
value = models.CharField(max_length=200)
elif TestPersonaName.objects.filter(name=persona_name).exists():
t= TestPersonaName.objects.get(pk=persona_name)
testpersona = TestPersona.objects.get(name=t)
if testpersona.key == persona_key:
testpersona.label= persona_key_label
testpersona.value = persona_key_value
You need too save the persona and return here as in the if above. Otherwise the interpreter exits this block and continues with
t=TestPersonaName(name=persona_name)
t.save()
testpersona = TestPersona(name=t,key=persona_key,label=persona_key_label,value=persona_key_value)
testpersona.save()
which replaces the value of t with a new persona that gets saved to DB. After every attempt to edit you'll keep ending up with a new record.
Hi I'm wondering if it possible or how to update single model object name inside for loop by his id using object.filter(pk=id).update(name='name') function
I try to do this but its not working in for loop. It's working only outside loop
EDIT
my edit view with for loop:
first i prepare data based on my database.Data can be modified by other methods so i keep they in global list schedule_table.
When I'm saving project object i want to update other data representing by schedule_table, using for loop.
def ProjectEditView(request, pk):
project = get_object_or_404(Project, pk=17)
schedule_table_load_form_db(project)#preparing list with data
Task_Schedule_TableView(request)
project_form = ProjectForm(request.POST or None, instance=project)
project_form_valid = project_form.is_valid()
if project_form_valid:
with transaction.atomic():
# save form in DB
project = project_form.save(commit=False)
project.save()
# modify other object based on changed list schedule_table
if schedule_table.__len__() > 0:
#my for loop
for p in schedule_table:
team = Team.objects.get(name=p.team)
phase = Phase.objects.filter(pk=p.pk).update(name=p.name,
project=project,
team=team,
order=p.order,
duration=p.duration,
prev=p.prev,
start=p.start,
end=p.end)
# some other staff..... outside the loop
return redirect('Project:ProjectListView')
context = {'project_form': project_form}
return render(request, 'Project/test.html', context)
function to prepare list with data:
