How can I dynamically change the file extension in a relative link from IPYNB to HTML when downloading a notebook as HTML?

I currently have a line inside a notebook (File1.ipynb):

[File 2](File2.ipynb)

When downloading both the files as HTML, this link is hard-coded, and hence when I click on the link in the generated *File1.html*, it can't find the file, because it refers to ipynb and not to html.

I could try:

* using sed to replace all occurrences of ipynb with html
* hard-coding html inside the notebook, which will prevent me from using the links when I'm editing the notebook.
But, is there an alternative?

Is there, perhaps, a way to specify two links inside the notebook such that if the browser fails to find the first one, it'll try the second? I tried searching for such a method. I couldn't find it.

jQuery/AJAX get Request format?

I've got a post request working pretty well

$.post('/discount', {
time_left: distance / 60000,
ban_id: id
})

So say for example, with my get request, all I want to do is actually grab some data from Python Flask, namely in my /discount route I have a variable named d_code which is my discount code. All I simply want to do is grab this variable and in the function of the GET request, I want to change the innerHTML of a paragraph just to show the discount code.

Fairly simple, but I don't really understand how to do the get request correctly.


Bonus: Do you think a flask app with gunicorn can handle 10k-100k users a day? Hosted on Heroku.

[AF] Delete table in Flask, using flask-sqlalchemy?

So, I want to delete a table in my database, this being a table called Comments as I know it will only make for a terribly scaled flask app. do I just delete the code for the model in models.py and make a migration?

Here is my models.py if anyone is interested:

What's the difference between Statsmodel's Poisson and GLM with Poisson family?

For Statsmodels (imported as sm), I do not know what the difference is between

sm.Poisson(Y,X)

vs

sm.GLM(Y,X,family=sm.families.Poisson())

Also, another oddity is that with the former I have to use fit_regularize but with the latter, if I try to fit_regularize, I will get None when I try to get a summary.

Updating fields in another model with custom save

Hello,

I have a few models with custom save definitions. I am looking to update a field in one model when I save another model based on a date comparison between the two. Unfortunately, I can't get this to work. I was wondering if someone could check out my code and see what I'm doing wrong.

models.py

class Person(models.Model):
first_name = models.CharField(max_length=250)
relation_name = models.CharField(max_length=250, blank=True)
last_name = models.CharField(max_length=250)
village = models.ForeignKey(Village)
earliest_case = models.ForeignKey('Case', null=True, blank=True, related_name='person_to_earliest_case+')
latest_case = models.ForeignKey('Case', null=True, blank=True, related_name='person_to_latest_case+')

def save(self, *args, **kwargs):
try:
earliest_litigation = Case.objects.filter(litigants__person=self).order_by('session__date')[0]
except:
earliest_litigation = None
try:
earliest_pledge = Case.objects.filter(litigants__pledges__giver=self).order_by('receiver__case__session__date')[0]
except:
earliest_pledge = None

if earliest_litigation and earliest_pledge:
if earliest_litigation.session.date > earliest_pledge.session.date:
self.earliest_case = earliest_litigation
elif earliest_pledge.receiver.session.date > earliest_litigation.session.date:
self.earliest_case = earliest_pledge
elif earliest_litigation:
self.earliest_case = earliest_litigation
elif earliest_pledge:
self.earliest_case = earliest_pledge
else:
self.earliest_case = None

try:
latest_litigation = Case.objects.filter(litigants__person=self).order_by('-session__date')[0]
except:
latest_litigation = None
try:
latest_pledge = Case.objects.filter(litigants__pledges__giver=self).order_by('-receiver__case__session__date')[0]
except:
latest_pledge = None

if latest_litigation and latest_pledge:
if latest_litigation.session.date > latest_pledge.session.date:
self.latest_case = latest_litigation
elif latest_pledge.session.date > latest_litigation.session.date:
self.latest_case = latest_pledge
elif latest_litigation:
self.latest_case = latest_litigation
elif latest_pledge:
self.latest_case = latest_pledge
else:
self.latest_case = None
super(Person, self).save(*args, **kwargs)



class Litigant(models.Model):

person = models.ForeignKey(Person, on_delete=models.CASCADE, related_name='cases')
case = models.ForeignKey(Case, on_delete=models.CASCADE, related_name='litigants')
role = models.ForeignKey(Role, related_name='litigant_role')

def save(self, *args, **kwargs):
super(Litigant, self).save(*args, **kwargs)
person = Person.objects.get(pk=self.person)
earliest_litigation = person.earliest_case
latest_litigation = person.latest_case
if earliest_litigation:
if self.case.session.date < earliest_litigation.session.date:
person.earliest_case = self.case
person.save(update_fields=['earliest_case'])
if latest_litigation:
if self.case.session.date > latest_litigation.session.date:
person.latest_case = self.case
person.save(update_fields=['latest_case'])
else:
person.earliest_case = self.case
person.latest_case = self.case
person.save(update_fields=['earliest_case', 'latest_case'])


When I save a `Person` model instance it updates the `earliest` and `last` case references just fine. However, when I add them as a `Litigant` it doesn't up

date their `earliest` or `last` case references as I was hoping the custom save method in `Litigant` model would do.

Am I missing something obvious here?

Thanks in advance for any help!

Jupyter Lab RKernel doesn't start. [Troubleshooting]

Hi, I am new to jupyter and also jupyter lab.
Installed it and it seems to work fine until i try to start the RKernel.
This is the error output from commandline.

the icu package is installed and the libicui18n.so file is located in /usr/lib/libicui18n.so

Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/home/johannes/R/x86_64-pc-linux-gnu-library/3.4/stringi/libs/stringi.so':
libicui18n.so.60: cannot open shared object file: No such file or directory
Calls: :: ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted

In the console I start and work with R normally.
Python Kernel works fine.

I am using Arch Linux...
Is this a known beginner issue?

Django Celery: Run automated Task once for each item in database

Working on a school project that requires sending an email to each person that created a page once per day, but needs to do it for each page and I'm just not sure where I need to go from here.

From Tasks.py

from celery.task.schedules import crontab
from celery.decorators import periodic_task
from .Listing import Listing
from celery.utils.log import get_task_logger
from datetime import datetime

logger = get_task_logger(__name__)


@periodic_task(run_every=(crontab(hour="10", minute="10")))
def run_daily_emails():
Listing.daily_hit_count()


From Listing.py

def daily_hit_count(self):

send_mail('Daily Hit Count!', get_templet('templates/realestate/HitCountEmail.html').render(
Context({
'MLSNumber': self.MLSNumber,
'dailyHitCount': self.dailyHitCount,
'totalHitCount': self.totalHitCount
})
), 'AutoPoshPlace@gmail.com', [self.listing_agent.email],
fail_silently=False)

self.dailyHitCount = 0


I need this to iterate through for every listing in the database, but I'm not sure how to do that.

Django Admin Page Routing to Different Urls

Hi,

Whenever I try to connect to my admin page on my local computer at localhost:8000/admin it tries to re-route me to a different page localhost:8000/admin/profile_html. My urlpatterns are as follows:

main_app:
urlpatterns = [
path('farms/', include('farms.urls', namespace='farms')),
path('admin/', admin.site.urls),
]

farm_app:

app_name = 'farms'
urlpatterns = [
path('', views.index, name='index'),
path('about/', views.about, name='about'),
path('form/', views.profile_form, name='profile_form'),
path('profile/', views.profile, name='profile'),

# Registration Urls
path('login/', views.login, name='login'),
path('signup/', views.signup, name='signup'),

]
Would anyone know why Django tries to do this? Thanks!
