CKEDITOR CONFIGS issue
I've added this config CKEDITOR_CONFIGS = { "default": { "removePlugins": "stylesheetparser", } as in https://github.com/django-ckeditor/django-ckeditor#if-you-want-to-use-allowedcontent but nothing changes. What I want is to add some microdata / tags and to be able to view them in the CKEditorWidget. The thing is that they get saved in the db but when displaying the source code in the widget ..... it's just basic HTML elements. widget = CKEditorWidget( config_name='CKEDITOR_CONFIGS', attrs={ # These get injected in the HTML as attributes of the textarea # and used by the ckeditor.

Django login required middleware not working
I'm new to Django and I'm trying to implement the django-login-required-middleware in my project to be able to direct all the users who are not logged in to the index page with login view. I Installed the pip install django-login-required-middleware, added login_required in my INSTALLED_APPS settings and added login_required.middleware.LoginRequiredMiddleware in my MIDDLEWARE. Then in my settings I ignore the views that I want to display to users even when They're not logged in. settings.py LOGIN_REQUIRED_IGNORE_VIEW_NAMES = [ 'index', 'register' ] However, when I run the server, I get the error Not Found: /accounts/login/ [22/Jan/2020 12:27:56] "GET /accounts/login/?next=/ HTTP/1.1" 404 4417 and in my browser: Request Method: GET Request URL: http://127.0.0.1:8000/accounts/login/?next=/ It seems like it automatically directs me to the accounts, even though my app is called movies_app and not accounts. Anyone knows how to fix this? Thank you very much! -

Django : how to use multiple databases?
I'm building a website with Django and I need to have a gps coordinate attribute in my User model. I will be using GeoDjango, which needs PostgreSQL and, since my website is already working with the sqlite3 default database, I need to install a PostgreSQL database to the project in order to create a Coordinates model in it and link it to the User model of the sqlite database. I found lots of tutorial on internet about "how to use multiple databases" but they are all very basics. Since I'm quite new to Django and web programming, I'm needing a in-depth tutorial about multiples databases. I have a few questions and I thank you in advance if you can answer one or more of those ! Note : I'm using windows 10 with PostgreSQL installed with the ubuntu app of windows. 1) How can I create and initialize the file for the new database in the Django project ? The file db.sqlite3 was automatically created with the Django project initialization so how can I create an other one ? 2) Do I need to use a new app for the GPS coordinates or can I use an existing one ? … -

Add a Matplotlib plot to Reportlab (platypus) directly
I want to add 3 different charts that I make using Matplotlib to a Reportlab pdf. I know I can save the plot and then add image on the report and then delete the image (since I don't want the image anymore). But I am curious if there is some way to do it directly using a b64 image or something like that. Moreover, I already have the charts made in Google charts on the client side, but since I resize them based on window size of the user, It is giving me weird images for my report. If there is a way to get consistent sized images from the Google charts itself, It'll be really cool. All suggestions are appreciated. Thanks
