Django application mod_wsgi error with apache
I'm hosting Django app on AWS ec2 with ubuntu 20.04 lts. I can run the app with venv on various ports. I want to bind the app with apache so that my users can visit my app with just the public DNS no ports, only on the default port. So I have installed apache2, mod_wsgi. My virtual host configuration. <VirtualHost *:80> ServerAdmin test@example.com DocumentRoot /var/www/html/app_folder ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /static /var/www/html/app_folder/static <Directory /var/www/html/app_folder/static> Require all granted </Directory> Alias /static /var/www/html/app_folder/media <Directory /var/www/html/app_folder/media> Require all granted </Directory> <Directory /var/www/html/app_folder/main_app> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess app_folder python-path=/var/www/html/app_folder python-home=/home/ubuntu/.local/lib/python3.8/site-packages/django/__init__.py WSGIProcessGroup app_folder WSGIScriptAlias / /var/www/html/app_folder/main_app/wsgi.py </VirtualHost> So after configuring this vhost i restart my apache2 but I get nothing on the public dns.

Translating code from Django version 1.9 to version 2.0
I am currently trying to get started with Django. But the book am using is using Django version <1.9 while the current version is >2.0 The problem am facing right now is this code: from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'', include('learning_logs.urls', namespace = learning_logs')) ] I have looked around and this is what I have written from django.contrib import admin from django.urls import include, path app_name = 'learning_logs' urlpatterns = [ path('admin/', admin.site.urls), path('learning_logs/', include('learning_logs.urls', namespace = 'learning_logs')), ] but when I run the server I get the error: raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. Any help with this. Thanks in advance -

Outputting two colums of dataframe into Django template using For Loop
I am trying to parse 2 columns of my dataframe(my_tweet_df) from views to Django. The dataframe is off Tweets data which I fetched from Tweepy. I hope for my output to look like this: USERNAME TWEET username1 tweet of username1 username2 tweet of username2 ..... ..... In my HTML page, code looks like this: <table class="table table-hover"> <tr> <th><h4>Username</h4></th> <th><h4>Tweet</h4></th> </tr> {% for key in my_tweet_df %} <tr> <td>{{key.author}}</td> <td>{{key.text}}</td> </tr> {% endfor %} </table> I do not know how to do so using for loop. I have tried passing dataframe: {% for key in dataframe %} with {{key.user}} and {{key.text}}. I know this approach is not correctenter code here as it is looping through range of dataframe not values of one column. I have tried converting to single columns and back to dataframe and passing like: my_tweet_df = pd.DataFrame(list(zip(my_tweet_df.user, my_tweet_df.text)), columns=['username', 'status']) But that again doesn't work because it is a 2D arary now and has a range of 2 only. Even if I try to pass them separately, I don't know how to do so using 2 for loops, like: {% for key in text %} <tr> <td>{{key}}</td> <td>{{key}}</td> </tr> {% endfor %} But in the above approach … -

Adding mysql database credentials to environment variable results in operational error
I'm deploying a django web app with Heroku. I have a MySql database. When my settings.py file contains hardcoded password and username for the mysql database, everything works.

Django: File upload and save using Ajax
I'm not sure if somehow the directory is wrong or there's just some kind of common mistake in my code, but I just am not able to save my uploaded file to a folder, or more specifically, the media folder as demonstrated in a lot of examples. I'm just taking a text field and the file and saving it in the DB using Ajax, and it works too, except that whatever file I'm selecting, it's not getting saved in the media folder even if I create one manually nor is it creating one on its own either. I can get this to work without Ajax but not with it. Maybe it's something related to how I'm sending and handling data over Ajax, but I've gone through tons of forums to try and fix it but no results so far. I've double checked everything else such as the settings.py config and the libraries that I've imported, everything looks to be in order. I'm sharing the code below. index.html <body> <div class="container-fluid"> <div class="col-md-4"> <form id="data" enctype="multipart/form-data"> <label for="docn"> <input type="text" id="docn" placeholder="Please enter document name"> </label> <label for="docc"> <input type="file" id="doc" name="docu"> </label> <button type="button" onclick="enterdata()">Submit</button> </form> </div> </div> <script> function … -

Django Search Implementation, conditional routing
I am trying to implement basic search functionality with Django. If exact search query page exists, display that page If there is a page title that contains what was queried, show results of all If neither, display a message stating no results found I'm just learning, so I tried functional views and class based views. I've spent a really long time on documentation/videos/textbooks and don't see how to get the intended behavior out of class-based view. I understand collecting object_list and getting query_set, but how do you then route to those three different conditions. I tried overriding dispatch() and as_views() method to no avail. Tried with a Django form class and without. For some reason, the functional view keeps executing the first try statement instead of throwing a DoesNotExist exception when the exact match isn't found. So it shows the entry page instead of the search results page. It seems like the request.GET is None type no matter what, as when I try to print nothing shows up. urls.py from re import search from django.urls import path from . import views from .views import IndexPageView, SearchView app_name = "wiki" urlpatterns = [ # ex: /wiki/ path("", views.index, name="index"), # path("", … -
