I have created a model called Certs, the models is registered and it is showing in the admin page, however I am trying to call it to run a check and try to make a task, but I am getting the error: No module named 'ships',
This is the structure of my project (note I am writing the code in reminders.py):
And here my code:
from django.core.mail import send_mail
from ships.models import Certs
from datetime import datetime, timedelta
b = Certs.objects.count()
def notifications():
for dates in range(b):
if Certs.exp_date[b] <= datetime.datetime.now() - timedelta(days=30):
send_mail(subject='Test',message='This is a reminder where you will be reminded about expiring certifications', recipient_list=['info#intermaritime.org'])
Thank you very much
Add the ships module to your INSTALLED section of settings.py

I wanted to insert model instance to database from a file. Ι wrote a python program to do so by importing models but every time Ι get this error:
ModuleNotFoundError: No module named 'exams'
I have tried putting the file in the same folder but then I got:
"Relative import error"
the expected result was to save model instance in the database.
You need to include more details, at least your files' paths. But if we assume that both models.py and I guess views.py files are in the same folder you should use:
from .models import exams
Unless what you are trying to import is the django models. In that case you use:
from django.db import models
As I said your questiong is poorly written and needs improvement to better understand your problem.
I have setup a scheduled task to run daily on PythonAnywhere.
The task uses the Django Commands as I found this was the preferred method to use with PythonAnywhere.
The tasks produces no errors but I don't get any output. 2022-06-16 22:56:13 -- Completed task, took 9.13 seconds, return code was 0.
I have tried uses Print() to debug areas of the code but I cannot produce any output in either the error or server logs. Even after trying print(date_today, file=sys.stderr).
I have set the path on the Scheduled Task as: (Not sure if this is correct but seems to be the only way I can get it to run without errors.)
workon advancementvenv && python3.8 /home/vicinstofsport/advancement_series/manage.py shell < /home/vicinstofsport/advancement_series/advancement/management/commands/schedule_task.py
I have tried setting the path as below but then it gets an error when I try to import from the models.py file (I know this is related to a relative import but cannot management to resolve it). Traceback (most recent call last): File "/home/vicinstofsport/advancement_series/advancement/management/commands/schedule_task.py", line 3, in <module> from advancement.models import Bookings ModuleNotFoundError: No module named 'advancement'
2022-06-17 03:41:22 -- Completed task, took 14.76 seconds, return code was 1.
Any ideas on how I can get this working? It all works fine locally if I use the command py manage.py scheduled_task just fails on PythonAnywhere.
Below is the task code and structure of the app.
from django.core.management.base import BaseCommand
import requests
from advancement.models import Bookings
from datetime import datetime, timedelta, date
import datetime
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail
from django.core.mail import send_mail
import os
from decouple import config
class Command(BaseCommand):
help = 'Sends Program Survey'
def handle(self, *args, **kwargs):
# Get today's date
date_today = datetime.datetime.now().date()
# Get booking data
bookings = Bookings.objects.all()
# For each booking today, send survey email
for booking in bookings:
if booking.booking_date == date_today:
if booking.program_type == "Sport Science":
booking_template_id = 'd-bbc79704a31a4a62a5bfea90f6342b7a'
email = booking.email
booking_message = Mail(from_email=config('FROM_EMAIL'),
to_emails=[email],
)
booking_message.template_id = booking_template_id
try:
sg = SendGridAPIClient(config('SG_API'))
response = sg.send(booking_message)
except Exception as e:
print(e)
else:
booking_template_id = 'd-3167927b3e2146519ff6d9035ab59256'
email = booking.email
booking_message = Mail(from_email=config('FROM_EMAIL'),
to_emails=[email],
)
booking_message.template_id = booking_template_id
try:
sg = SendGridAPIClient(config('SG_API'))
response = sg.send(booking_message)
except Exception as e:
print(e)
else:
print('No')
Thanks in advance for any help.
Thanks Filip and Glenn, testing within the bash console and changing the directory in the task helped to fix the issue. Adding 'cd /home/vicinstofsport/advancement_series && to my task allowed the function to run.'
I'm aware of pdb built-in Python library for debugging Python programs and scripts. However, you can't really use it for debugging Django apps (I get errors when I try to use it in views.py). Are there any tools that I can use when Django's traceback isn't helpful ?
EDIT:
from .forms import TestCaseForm, TestCaseSuiteForm
from .models import TestCase, TestSuite
from django.contrib.auth.forms import UserCreationForm
from django.views.generic import FormView, ListView
from django.contrib.auth.models import User
from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required
from django.contrib.auth import logout
import pdb
class ListAllTestSuites(ListView):
template_name = 'list.html'
context_object_name = 'username'
def get_queryset(self):
pdb.set_trace() # <-- setting a trace here to diagnose the code below
queryset = {'test_suites': TestSuite.objects.filter(user=self.request.user),
'username': self.request.user}
return queryset
you forgot the exact error message and full traceback, and, more importantly, you forgot to explain how you executed this code to get this result...
But anyway: from the error message, you're obviously trying to execute your view file as a plain python script (cf the reference to __main__). This cannot work. A view is a module, not a script, and, moreover, any module dependending on Django needs some setup done to be imported (which is why we use the django shell - ./manage.py shell - instead of the regular Python one).
For most case, you can just launch the django shell, import your module and use pdb.runcall() to execute some function / method under the debugger (no need to put a breakpoint then, but that's still possible).
Now views require a HTTPRequest as first argument which make them a bit more cumbersome to debug that way (well, there is django.tests.RequestFactory but still...), so your best bet here is to set your breakpoint, launch your devserver (or restart it - if it didn't already did, as it should), point your browser to the view's url, and then you should see the debugger's prompt in your devserver's terminal.
I am trying to import my models into views.py but I am unable to do so. However I am able to register them on the admin site but when I use the same code I used in admin.py to import the models into views.py, I get an error. I am using djongo so I am not sure if that changes anything about how to import them and I cannot seem to find the documentation for it.
models.py
from djongo import models
class Round(models.Model):
round_num = models.IntegerField(default=0)
admin.py
from django.contrib import admin
from .models import Round
admin.site.register(Round)
views.py
from .models import Round
When I try and run my views.py file I get the following error: ModuleNotFoundError: No module named 'main.models'; 'main' is not a package
Also my views, admin, and models file are all in the same directory. I have made the migrations and I can see my Round model in MongoDB. The only thing I cannot do is import it to the view
You need to have an __init__.py file in your directory. It should be inside of your main folder and at the same level as your views.py and models.py
As a workaround, since the models properly migrate to MongoDB. Using pymongo I have just connected to Mongo and have rendered data into my views this way. It works fine so if anybody else has an issue loading in their models, you can always just connect directly to the DB.
I have a Django model with some static methods. I'd like to call the methods from outside the application (cronjob).
The model I have:
class Job(models.Job):
#Irrelevant information
#staticmethod
def methodIwantToCall():
#statements
I have the following python file that I'm using for the cron job:
#!/usr/bin/python
# -*- coding: UTF-8 -*-
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from myapp.models import Job
Job.methodIwantToCall()
At first, I was having an error about DJANGO_SETTINGS_MODULE not being set and I fixed that, however, now I have the following error: No module named myapp.utils
I feel like I'm doing something that I'm not supposed to do. So how do I call that static method the way I want it to be called?
EDIT: It looks like the paths are getting messed up when I'm importing from outside Django. For example, I have an import in my models file, when I call the cron file it fails importing with the message ImportError: No module named myapp.utils even though it's working.
The proper solution is to create custom manage.py command.
Assuming your cron job code resides in the same directory as your settings file, use the following setup code at the beginning:
from django.core.management import setup_environ
import settings
setup_environ(settings)
