Django:` Date: Wed, 09 Jan 2019 09:25:20 GMT Server: WSGIServer/0.2 CPython/3.7.1` will automatically added to my code
I'm creating a website using the django framework. But recently, I found something strange. I loaded the page at 127.0.0.1:8000, but failed. I checked the chrome console log and found a js file with errors. Then I check the error in the js file and find some strings added to my code automatically. If I clean up the cookies and reload the page, I might load the page successfully or these strings might still appear in other js files. Why is it happen? /error js file if ($element.data('on-label') !== undefined) onLabel = $element.data('on-label'); if ($element.data('ofDate: Wed, 09 Jan 2019 09:25:20 GMT Server: WSGIServer/0.2 CPython/3.7.1 f-label') !== undefined) offLabel = $element.data('off-label'); if ($element.data('icon') !== undefined) icon = $element.data('icon'); Sometime below two strings will add into my code automatically When I first visited the page. I can't find any error log in PyCharm when i run runserver, only can see chrome log about the wrong js file. Date: Wed, 09 Jan 2019 09:25:20 GMT Server: WSGIServer/0.2 CPython/3.7.1 -

How do I create a custom 410 error page using the Django Redirect App?
I am redesigning a website with lots of old (and very poorly optimized) content. It doesn't make sense to migrate the old content, so I am using the Django Redirects App to raise 410 errors in case anybody discovers a link to the old website. https://docs.djangoproject.com/en/2.1/ref/contrib/redirects/ I am currently getting the default Chrome 410 error page. How do I deliver a custom 410 error page? -
Unique autogenerated ID for differet django models
I have 3 model classes that inherit from a parent abstract class, like so: class ParentClass(models.Model): class Meta: abstract = True class ChildClass1(ParentClass): ... class ChildClass2(ParentClass): ... class ChildClass3(ParentClass): ... I was wondering if there was a way to let Django generate id's as usual, but making sure that no instances of either ChildClass1, ChildClass2, or ChildClass3 will have overlapping id's. So for example the following code: a = ChildClass1.objects.create() b = ChildClass2.objects.create() c = ChildClass3.objects.create() print(a.pk) print(b.pk) print(c.pk) shuld return: 1 2 3 -

Creating a unique object using DateField()
I would just like to create a model that essentially prevents the same date being selected by two different users (or the same user). E.g if User1 has selected 2019-01-10 as a "date" for a booking, then User2 (or any other Users) are not able to create an object with that same date. I have created a very basic model that can allow different Users to create an object using the DateField(). Using the Django admin page, I can create different instances of objects by two different Users (admin and Test_User). In order to try to ensure that a new object can't be created if that date has already been used by a different object I have tried the following approach: a compare function that utilizes __dict__. models.py from __future__ import unicode_literals from django.db import models, IntegrityError from django.db.models import Q from django.contrib.auth.models import User from datetime import datetime class Booking(models.Model): date = models.DateField(null=False, blank=False) booked_at = models.DateTimeField(auto_now_add=True) booking_last_modified = models.DateTimeField(auto_now=True) class PersonalBooking(Booking): user = models.ForeignKey(User, on_delete=models.CASCADE) def compare(self, obj): excluded_keys = 'booked_at', '_state', 'booking_last_modified', 'user', return self._compare(self, obj, excluded_keys) def _compare(self, obj1, obj2, excluded_keys): d1, d2 = obj1.__dict__, obj2.__dict__ for k,v in d1.items(): if k in excluded_keys: continue try: … -
Authorization of microservices in monolith application
I have a django application that puts a task in a queue. Another service is used to read that queue and process some files. At the end I need to save the processed files in the database managed by the django application. I do not want to give the "microservice" access directly to the database, since I want the responsibility only to be to process the files. So I wanted to post the changes to django using HTTP request. The problem is that I do not have any authorization at the time, even though I know that HTTP from this type of machine is to be accepted. For the django application I use JWT as an authorization token. How is the best way to approach this type of problem? Maybe just send a token together to the queue? But how to make such token? It's not certain when the process will be executed.. -
Django load ES6 javascript file
I would like to use the import feature in ES6 in index.html in django. I do not want to compile to ES5 for browser compatibility.

apache2 with django - can't write to log file

How to integrate django project with nextcloud calendar
We're planning to write a Django application that can manage events for a group of users. The things that we need: There is an easy way for the admins to create new events and upon creation users are notified (per email) and can confirm or decline attendance. The user can integrate these events in their calendar client, e.g. thunderbird, iOS, etc. Depending on people attending to the event, we can create some stats, overviews, graphs, etc. Users can change their RSVP status and the admins are notified per email. Events will have probably several linked data to them (maybe some maps, documents, etc.) and other fields for categories, etc. Events might be recursive or one-time events. There is an easy way to add exceptions for recursive events. There is an overview for all events and RSVP status for the events is easily accessible. The count of attendees is listed for each event. The events overview can be filtered by different criteria (date range, category, ...) We want to use a Django project for managing stats, linked media, listings, etc. And the plan was to add fields for the scheduled date + recurrence. But all existing calendar alternatives for Django I've … -
How to compare some_time|timeuntil with specific time interval in Django templates?
I'm making a new label on my BBS. (When an article is a relatively new one, then a label says 'this is new one' appears.) After reading Django Docs I know |timeunitl returns the value from given time to now. I want to compare this value to a specific time interval such as two days or two hours. So I tired below {% if article.created_at|timeunitl < 2 %} <span class = "label label-new">NEW</span> {% endif %} However, I can't see <span class = "label label-new">NEW</span> in actual page no matter how I change the value of the right side.

How django resolve the foreign key in its models.py?
I am wondering how django decides which column or field will act as foreign key to another model in One to Many relationship. class Department(models.Model): dept_name = models.CharField(max_length=100) dept_head = models.CharField(max_length=100) dept_abbrv = models.CharField(max_length=100) class Employee(models.Model): dept = models.ForeignKey(Department) emp_name = models.CharField(max_length=100) Now how django knows which column of Department (dept_name, dept_head or dept_abbrv) will map to 'dept' in Employee. In my admin page of Employee details if I have to add a new employee, there is dropdown listing all Department.dept_name against 'dept'. How django decides that? Why it is not dropdown list of dept_head or dept_abbrv ? -
