I wanted to access the value of the function outside in Django rest framework. I have checked this function which return value but I want to call that return value in another function.
I have tried this approach where I'm getting output ticketid as 'None'
views.py:
def GetUserTaskId(request):
userid = request.data.get('UserId')
ReportId = request.data.get('ReportId')
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[USP_GetUserTaskId] #UserId=%s, #Ticket=%s', (userid, ReportId))
result_set =cursor.fetchall()
for row in result_set:
TaskId=row[0]
return Response({"TaskId":TaskId})
def inserttask(request):
ticketId = GetUserTaskId(request)
print("ticketId--->",ticketId)
if ticketId is not None:
/***somecode***/
Why not do something like this?
# common.py
def get_task_id(user_id, report_id):
cursor = connection.cursor()
cursor.execute('EXEC [dbo].[USP_GetUserTaskId] #UserId=%s, #Ticket=%s', (user_id, report_id))
result_set = cursor.fetchall()
for row in result_set:
TaskId=row[0]
return TaskId
# views.py
from .common import get_task_id
def GetUserTaskId(request):
userid = request.data.get('UserId')
ReportId = request.data.get('ReportId')
task_id = get_task_id(userid, ReportId) # call our function
return Response({"TaskId": task_id})
def inserttask(request):
userid = request.data.get('UserId')
ReportId = request.data.get('ReportId')
ticketId = get_task_id(userid, ReportId) # call our function
print("ticketId--->",ticketId)
if ticketId is not None:
pass

i have imported all the required module also but it's not working but the first login page is working . if anybody knows about this .Can anyone help me out of this.
You've coded two #login_manager.user_loaders. When you do that multiple times, the last one wins. (See here)
You'll have to choose which of Registration or Memberdb your app will use to represent a logged-in user.
I am trying to embed the link of the issue id from JIRA.
I want JIRA issue id to be an embedded link to the JIRA.

This is the calling function. APPid and toAddress will be passed in from different UI.
from Complaince import ComplainceServer
jira = ComplainceServer(jiraServer, username, password)
issues = jira.checkComplaince(appid, toAddress)
I want issueid to be an embedded link.
currently the email sends as below:
MT-4353(https://check.com/login/browse/MT-4353) - Site Sc: DM isg_cq5
but i want [MT-4353] as hyperlink to the URL https://check.com/login/browse/MT-4353
Non-coder here. I have an activity I'm editing for beginning students. It was created a year ago by someone else. The project is pre-created for students. They are supposed deploy it, create a bucket, and upload some files to the bucket from within the app. When I try it, I get this error:

Please help. I don't have a clue how to fix this, but I need to get this project working for the students to use.
Thanks so much,
Chrys
That's because there's no default bucket attached to your current project.
You can create a bucket with gsutil or the cloud console and then hardcode the value in your bucket_path function.
Also you can keep your current bucket_path helper function that returns the bucket_name from app_identity.get_default_gcs_bucket_name() and then create a default bucket in the new console by visiting your app engine's application settings in the cloud console https://console.cloud.google.com/appengine/settings?project=
I've looked at all the related answers but none fixed my issue. I'm trying to save an object that's already created with no luck. I could see the view getting executed and the values I updated for the object but changes are not reflecting in the database. Here is the code snippet of the view and the model.
views.py
class Workspace(_LoggedInMixin, View):
def get(self, request):
user = self.request.user
components = ComponentModel.objects.filter(Q(user=user) | Q(user=None)).order_by('time')
component_status = request.session.get('component', None)
request.session['component'] = None
params = dict(components=components, status=component_status)
return render(request, 'workspace.html', params)
def post(self, request):
data = request.POST
formtype = data['form-type']
error = None
user = self.request.user
if formtype == 'component':
if data['action'] == 'create':
try:
if not os.path.exists('D:/' + self.request.user.username):
os.makedirs('D:/' + self.request.user.username)
cparent = ComponentModel.objects.get(pk=data['cparent'])
component = ComponentModel(user=user, name=data['cname'], time=dt.now(), stats=data['cstats'],
output=data['coutput'], parent=cparent)
component.save()
file = open('D:/' + self.request.user.username + '/' + str(component.id) + '.py', 'w+')
usercode = data['usercode']
usercode = "\n".join(usercode.split("\r\n"))
file.write(usercode)
component.codefile = 'D:/' + self.request.user.username + '/' + str(component.id) + '.py'
component.save()
request.session['component'] = {'name': data['cname'], 'message': 'Component created successfully!'}
except Exception as e:
component.delete()
error = e.message
elif data['action'] == 'delete':
try:
c = ComponentModel.objects.get(pk=data['compid'])
cname = c.name
c.delete()
os.remove('D:/' + self.request.user.username + '/' + data['compid'] + '.py')
request.session['component'] = {'name': cname, 'message': 'Component deleted successfully!'}
except Exception as e:
error = e.message
elif data['action'] == 'save':
try:
if not os.path.exists('D:/' + self.request.user.username):
os.makedirs('D:/' + self.request.user.username)
cparent = ComponentModel.objects.get(pk=data['cparent'])
component = ComponentModel.objects.get(pk=data['compid'])
component.user = user
component.name = data['cname']

print component

if error is not None:
components = ComponentModel.objects.filter(Q(user=user) | Q(user=None)).order_by('time')
params = dict(error=error, components=components)
return render(request, 'workspace.html', params)
return redirect('/workspace')
models.py
class ComponentModel(models.Model):
class Meta:
# overriding the default table name with the following name
db_table = 'components'

def __str__(self):
return "{id: %s, name: %s, user: %s, time: %s, parent: %s}" % (
self.id, self.name, self.user, self.time, self.parent)
The second save call in data['action'] == 'create' and the save call in data['action'] == 'save' are not updating the database. I appreciate any help. Thank you.
Your super call is incorrect. Update so that self is not called as a method argument - as you have it written it will always fail.
In addition, you are not raising the exception when a save is not completed, so you have no idea if there was an error unless viewing the std output. You probably want this to actually raise an error.
Update as such -
def save(self, *args, **kwargs):
try:
super(ComponentModel, self).save(*args, **kwargs)
except Exception as e:
raise Exception("Something went wrong while saving the component. Details - %s" % (e.message,))
