No such table on django website deployment on Heroku
I was previously facing issues on deploying my django app on Heroku regarding static directories.But now that I have been able to deploy my website after changing settings.py , there is a error being thrown called 'no such table'.Then I went to stackoverflow for solutions but nothing worked.I am adding my settings.py file here which also has the stackoverflow solutions.I have written a if statement for using PostgreSQL as mentioned in a stackoverflow post but that also don't work.You may see that if statement in last line.My requirements.txt is all correct , so no problem in that.Plz help me. from pathlib import Path import os # Build paths inside the project like this: BASE_DIR / 'subdir'.

Compare set of model instances with their conterparts in DB | Django
I have a question reg. comparing big set of model instances with data in DB. for example I have a model with 5 fields: model Foo(models.model) fields1 = models.Integerfield() fields2 = models.Integerfield() fields3 = models.Integerfield() fields4 = models.Integerfield() fields5 = models.Integerfield() class Meta: unique_together = (‘field1, field2’) and I have 400.000 model Foo entries saved in DB. Also I have 400.000 +/- few instances in memory(in python)of the same model generated from internet CSV file (without pk set). Question is – what is the most efficient way to do following: 1)If instance in python equal to same instance id DB – keep instance in DB. 2)If instance in python not equal to instance in DB – update instance in DB. 3) If instance in python does not coincide to any instances in DB – write it to DB. 4) If no instances in python coincide to particular instance in DB – delete instance from DB. Its should be bulk operations or RAW SQL as sample size is quite big. Thank you. -

JavaScript add class not working on Django template
I want to use this: var btns = document.getElementsByClassName("active-btn"); // Loop through the buttons and add the active class to the current/clicked button for (var i = 0; i < btns.length; i++) { btns[i].addEventListener("click", function() { var current = document.getElementsByClassName("active"); // If there's no active class if (current.length > 0) { current[0].className = current[0].className.replace(" active", ""); } console.log(this.className) this.className += " active"; }); } in my base.html to have a navbar that automatically toggles this active class.

Django and synced tables
I am looking for a relatively simple implementation to get a synced table into my project.

I am looking for some idea which way to head ... maybe creating the django-tables2 table from a json that gets periodically called (like here) or trying to implement datatables.net by myself (maybe like suggested here)? -

How do I use a POST method to communicate with an external API in Django?
I received help from my instructor to figure out the GET command.

Regex for searching or to filter queryset in django
I am trying to filter the queryset by options that are sent through the URL. Like the following: http://127.0.0.1:8000/<int:pk>/year=2020&director=ChristopherNolan&production=warnerbros/ where the order does not matter. It should be valid even if the user retrieves using: http://127.0.0.1:8000/<int:pk>/director=ChristopherNolan&year=2020&production=warnerbros/ or just http://127.0.0.1:8000/<int:pk>/director=ChristopherNolan/ Is there any way to write regex to do this and retrive the fields in args and/or kwargs. -

Django : Display static images in production
I'm hosting an API made with Django on Heroku. I'm trying to upload an image from the django administration page to the "images" folder located in the "static" folder (/static/images/name.png). After uploading my image, when I try to display it (url.herokuapp.com/images/name.jpg), I get a not found page. My code is working well when I'm running in local. This is my code : settings.py : # URL prefix for static files STATIC_URL = '/static/' # Absolute path to the directory in which static files should be collected STATIC_ROOT = os.path.join(BASE_DIR, 'static') # Use for template STATIC_TMP = os.path.join(BASE_DIR, 'static') os.makedirs(STATIC_TMP, exist_ok=True) os.makedirs(STATIC_ROOT, exist_ok=True) MEDIA_URL = "/images/" # Additional locations for static files STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static/images') ] MEDIA_ROOT = os.path.join(BASE_DIR, "static/images") urls.py : from django.contrib import admin from django.urls import path, include from django.conf.urls.static import static from django.conf import settings urlpatterns = [ path('admin/', admin.site.urls), path('v1/', include('store.urls')), ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) models.py : class Shop(models.Model): name = models.CharField(max_length=255) logo = models.ImageField(verbose_name="Logo") path = models.URLField() email = models.EmailField() phone = models.TextField() def __str__(self): return self.name Thanks by advance for your help.
