Issue in django squashed migration while migrating the app from django 1.11 to django 3.0
The app was running on 1.11. we are migrating it to 3.0. As it is a multi-tenanted system we use django-tenant-schema. Consider the app is running on django 1.11, I ran django migrate_schemas command, it ran all the migrations, Then I switch to different virtualenv where django 3.0 is installed but here the showmigrations command says below migration hasn't run 0023_auto_20180921_1708_squashed_0025_auto_20180921_1727 It should be same in both django versions, isn't it? In screenshot, left side is django 3.0 and right side is django 1.11 -

facing a weird bootstrap behavior in chrome
I have a django-bootstrap project in which an html page has a dynamically generated table with data-toggle popovers on td elements. in firefox, opera and edge everything works perfectly fine and the popover show up, but in chrome they just don't. however when I copy paste the same code in a new blank html test page unrelated to the project it works (minus a few css issues for the rest of the page). am really out of my wits end trying to understand the behavior I tried: emptying cache and hard reload multiple time no success forcing the state to trigger popover no success no errors/warnings showing up in console restart server and dev machine no success clear a week's worth of cache and browser history check if there is a chrome extension blocking it. (none am aware of since the test page is working fine) made sure my jquery bootstrap 4 cdn's are up to date I really have no clue what to turn to to find the source of the behavior. what steps do you do you guys go through if an element is randomly not showing on your page or you going through unexpected behaviors -

Unable to display JsonResponse in Django web project
I am working on a django project. I want to display the result of a query with JsonResponse, but I can only get the raw data, rather than the colourful Json response.

object not being saved on database while using Ajax on django
I have this form that uses ajax on post method when saving new todo object on database and it works fine. When I add new entry on the form, it is being saved on the database and displays the new entry on the end user. However, I made a code that whenever I clicked those tasks below(the whole div), (Grocery, eat snack, etc see the picture for reference), the object's completed attribute should be True(it means the end user is done doing the task) and the texts should have a line-through on it. But, the completed attribute of each tasks listed below is not being saved as True on the database after every time I add a new entry and click the tasks, it only adds a line-through style on text, It will only be saved when I refresh the page and then click on those tasks again. in short: working: adding new entry, it displays new entry on end user without refreshing the page not working: clicking the task to make the completed attribute True after adding new entry. it only adds line-through style on each texts. (This will work ONLY if I refresh the page and then click … -
Nested writable serializer to process flattened normalized request data
I have a nested writable serializer. class GamerSerializer(serializers.ModelSerializer): account= AccountSerializer() document = DocumentSerializer() class Meta: model = Gamer fields = [ 'chosen_game', 'gamer_experience' ] This serializers is supposed to create Account object, a Gamer object related to Account as well as Document object related to Gamer. By default the nested serializer always accepts nested objects as data like this: serializer = self.get_serializer(data= { account: {...acount}, document: {...document}, chosen_game: "Minecraft", "gamer_experience": "1 year" } ) but I want the serializer to accept normalized flattened data( we assume that names of the model attributes do not overlap). Like this : serializer = self.get_serializer(data= { account_name: '', account_type:'', document_name: '', document_file: '', chosen_game: "Minecraft", "gamer_experience": "1 year" }) How can I achieve this result ? -

django-cors-header problem with authorization cookies
I am using Django base authorization to protect specific routes of my API (using @login_required decorator), and Insomnia to test them out. Using Insomnia I can login using my ```api/auth`` route and then access to every protected route of my APIs. The problem comes with React: I have my React app running on localhost:3000 and my Django APIs on localhost:8000. When I log in though the login page (made with react and react-router-dom) it just works. But after that, if I open the HomePage (which fetches data from a login_required route) I get a 404 response ( which is caused by @login_required ). I tought that the problem was because of fetch and cookies, But I can't figure out a way to solve it. It seems like Insomnia automatcally stores the cookie returned by api/login but the same doesn't happen with react. I've also already tried to set credentials to include and same-origin in my login fetch. Did someone already experienced this problem?

Creating a single API with models which dont have direct relationship with each other
I have these 3 models. Among these 3 models, Flightdetails and Passenger are in relationship with the third model Booking. But the 1st and the 2nd model doesnt have any relationship. And in the frontend I have a form like that for the booking. What I want to do is create an POST API from passenger model where user can submit the passenger's info and it is booked. BUt what my senior is demanding is that in the same post api, I should also have the flight id( primary key) request, so that when I submit the form or book, it (the object) should also have its own flight id.

Deploy Django 1.7 application to Apache2 with WSGI
I am trying to deploy an old Django application (1.7) to the Apache2 server on Debian. I am finally able to run the app with ./manage.py runserver but I had no success in getting the mod-wsgi working. I've never wrote a server side application in Python so please forgive me if I am missing something obvious. These are the steps I followed Everything I tried is with /usr/bin/python which is 2.7 - I know, I should be using virtuelenv but I didn't want to add even more complexity to the while thing (since I am not familiar with it) installed mod-wsgi with apt-get install libapache2-mod-wsgi Add following config to the /etc/apache2/mods-enabled/wsgi.conf Apache2 restart <IfModule mod_wsgi.c> WSGIScriptAlias / /home/rosasystem.pl/public_html/rosasystem/rosasystem/wsgi.py WSGIPythonHome /usr/bin/python WSGIPythonPath /home/rosasystem.pl/public_html/rosasystem LogLevel warn <Directory /home/rosasystem.pl/public_html/rosasystem/rosasystem> <Files wsgi.py> Order deny,allow Require all granted </Files> </Directory> </IfModule> Since then, I keep getting this error message in the error.log - most of the stuff I've googled suggest that there is a Python version discrepancy between mod-wsgi and system/virtualenv Python version which in this doesn't make sense because everything is Python 2.7.

Instead I've made a function my on my own that uses uuid() to generate the custom id also using the timestamp: from datetime import datetime as dt from uuid import uuid1, uuid3, uuid4 def generate_id(): timestamp = str(dt.timestamp(dt.now())) return uuid3(uuid4(),timestamp) Now if I open the interactive shell: python manage.py shell and I call my function several time, this is what I get: >>> generate_id() UUID('bd8279f1-9b4b-3d7d-8932-f9e725f17045') >>> generate_id() UUID('0c2ec2ad-b062-3915-a9e9-22842c6f5ea2') >>> generate_id() UUID('2289202b-f252-3b27-bcae-cd44825bf4e0') >>> generate_id() UUID('88676ea9-4902-36ac-857d-929cb133089c') >>> generate_id() UUID('4a18b33e-12f0-3803-8ff0-0c4f0d1c849c') but when I try creating 2 users: from users.models import CustomUser >>> one = CustomUser.objects.create_user(email='hhh@jaja.com',password='JJlsaks16112') >>> two = CustomUser.objects.create_user(email='ttth@jija.com',password='JJlsaks16112') Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) File "/usr/local/lib/python3.8/site-packages/django/db/backends/mysql/base.py", line 73, in execute return self.cursor.execute(query, args) File "/usr/local/lib/python3.8/site-packages/MySQLdb/cursors.py", line 206, in execute res = self._query(query) File "/usr/local/lib/python3.8/site-packages/MySQLdb/cursors.py", line 319, in _query db.query(q) File "/usr/local/lib/python3.8/site-packages/MySQLdb/connections.py", line 259, in query _mysql.connection.query(self, query) MySQLdb._exceptions.IntegrityError: (1062, "Duplicate entry 'b448f583acfb31b7955926689b60f28a' for key 'PRIMARY'") The above exception was the direct cause of the following exception: Traceback (most recent call last): File … -
How to set backgroundcolor and border for each array element using javascript or jquery?
I am trying to set separate background and border for each element in the array using JavaScript something like this. Until now what I have done outputis below. As I add a new element to the array, it will stretch the background. let skills = []; function displayname() { console.log(document.getElementById("namehere").value); x = document.getElementById("namehere").value; skills.push(x); console.log(skills) document.getElementById("skill-set").innerHTML = skills document.getElementById("skill-set").style.border = "1px solid blue"; document.getElementById("skill-set").style.backgroundColor = "yellow"; document.getElementById("skill-set").style.padding = "5px"; document.getElementById("skill-set").style.display = "inline-block"; document.getElementById('namehere').value = " "; } <label>Enter the skills: </label><br> <input type=t ext id="namehere" onchange="displayname()"> <div id="skill-set"></div>
