What are the ways to achieve it? Should I create a separate app for it or maybe a separate page that will only be available for superusers -

Django: Allow User To Set Default TimeZone For Accurate DateTimeInput
I'm working on an app that's revolved heavily around users entering data based on very specific date and time inputs. By default my settings.py is: TIME_ZONE = 'UTC' USE_L10N = True USE_TZ = True As you probably already know.. this means all data will be set to timezone UTC in the database which in my PostgreSQL shows as such 2020-03-26 15:22:45+00 which is all good and gravy except that a user not in UTC+00 is still setting all their DateTime inputs too it. Resulting in inaccurate data. It seems the best measure would be to allow users to force a default timezone in their account settings page. I see less room for server, traveling, proxies, VPN, etc. issues going this route. An alternative route would be for the app to determine the timezone and then input it with the proper localization. I'm not totally sure the best approach but I still am leaning towards a fixed default time. Simplicity in development/maintenance is also a key factor I'm ruling in here. My question is what would be the best solution that would allow users to input their data knowing that they are entering it for the right timezone? Also, what is … -

Automatic monthly updation of data in django

Django - Using TimeField() as a foreign key
I have a Meeting model which has meeting_hour getting its value from MeetingHour model. But I'm getting an error as follows after submitting form: Cannot assign "datetime.time(14, 0)": "Meeting.meeting_hour" must be a "MeetingHour" instance.

What Server provider is best for a Django-MySQL back end?
I just finished my 4 month project to create a mobile app. I built my own backend API (only returns JSON) in Django to fetch data from my MySQL database and I have completed the front end user interface in Swift. Up to this point, both my Django API and my database have been running locally on my Mac. I am ready to deploy my mobile app and I understand this requires pushing my backend API/database onto a server. Which server provider is best for my needs? Thank you. -

How to use Javascript function on input elements in a for loop. Django
I'm working on a Django form that can calculate values in real time. I would like the javascript function to work for all rows which consists of 3 input fields each. I tried assigning each input field with an id followed by a forloop counter. I also looped through the function hoping that it will work for all the ids, a1,a2,a3... b1,b2,b3... c1,c2,c3... However, the function only worked for the last row. Here's the javascript I used: <script type="text/javascript"> for (i = 0; i < {{ total_rows|safe }}; i++) { $('input').keyup(function(){ var firstValue = Number($('#a'+i).val()); var secondValue = Number($('#b'+i).val()); document.getElementById('c'+i).value = firstValue * secondValue; }); } </script> Here's my template: <form> {% csrf_token %} <table> <thead> <tr> <th>Quantity</th> <th>Unit Price</th> <th>Amount</th> </tr> </thead> <tbody> {% for item, amount in loop_list %} <tr> <td> <input id="a{{ forloop.counter }}" type="text" class="form-control" placeholder="" name="quantity1" value="{{ item.quantity }}"> </td> <td> <input id="b{{ forloop.counter }}" type="text" class="form-control" placeholder="" name="unit_price1" value="{{ item.product.unit_price }}"> </td> <td> <input id="c{{ forloop.counter }}" type="text" class="form-control" placeholder="{{ amount }}" readonly> </td> </tr> {% endfor %} </tbody> </table> </form>
