Access session variables from render funcition of the plugins in Django Cms
I have a view called create_pdf(request), which takes a json from the body of the httprequest, and I have some plugins defined in a page (/input_url). After rendering the page, I save it to pdf in here: pdfkit.from_url(input_url, output) Being the output the folder I want the pdf in. I want to fill the plugins with the info contained in the json, but the only way to access it is by saving the json in a folder and open the file in each of the plugins. Is there anyway to save globally the instance of the json by session and access it from the render function of the plugins? I know I can save the info in a session variable from the view, but I don't know the way to access to it from the render function of the plugin. Thanks for helping. -

How do I use a different EMAIL_BACKEND for certain emails in django
I'm trying to send emails from 2 different backends. Most emails are being sent via AWS SES but I want a few from Outlook365 (because these will actually be stored/reviewed). So within settings.py I have EMAIL_BACKEND = 'django_ses.SESBackend' to use the AWS SES backend. I'm then trying to create a new connection when I want to send from Outlook as follows: with get_connection( backend = 'django.core.mail.backends.smtp.EmailBackend', host = 'smtp.outlook.office365.com', port = 587, user = 'myuser@mydomain.co.uk', password = 'password!', use_tls = True, ) as connection: email = EmailMultiAlternatives( subject=context['subject'], body=text_message, from_email='myuser@mydomain.co.uk', to=[user.email], connection=connection ) email.attach_alternative(html_message, "text/html") email.send() This generates the error: smtplib.SMTPSenderRefused: (530, b'5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [LO2P265CA0076.GBRP265.PROD.OUTLOOK.COM]', 'myuser@mydomain.co.uk') However, if I set these within settings.py (instead of using AWS) it will work (but means all other emails also go from here). Why isn't my get_connection working and how do I fix it? -

why compressing this less file doesn't work?
Story is that I got to work in old Django project. I did some changes to models, and only models. But now I get error when compressing less file using django-compressor. What is odd: I can compress files locally, but server pipeline fails. The command that fails is: python manage.py compress --force error I get is: CommandError: An error occurred during rendering /code/app/portal/templates/portal/presentation_company.html: ParseError: Unrecognized input.

Please help. I'm stuck, .less noob with no idea what to do. My biggest problem is that reverting changes done to models doesn't solve problem! And I'm not sure if that's important: Server uses GitLab Pipelines to deploy Dockerized Django app. -

How to save django manytomany field without through table
I face a vicious cycle that I cannot break out of; Lets say I have a following model: class AgregatorProductCoupon(models.Model): AgregatorProductId = models.ManyToManyField(Product, related_name="coupons", db_column='AgregatorProductId', verbose_name=_("Agregator Product Id")) class Meta: managed = True db_table = 'AgregatorProductCoupon' when I try to save an instance, I get an integrity error stating "<AgregatorProductCoupon: AgregatorProductCoupon object (None)>" needs to have a value for field "id" before this many-to-many relationship can be used. but when I try to save without the m2m rel, I obviously get an error for a required field missing. Cannot insert the value NULL into column 'AgregatorProductId', table 'test_dbo.dbo.AgregatorProductCoupon'; column does not allow nulls. INSERT fails. I cannot redesign the tables as they are bound to other places too. How to go about it? Any help would be much appreciated. -

Which approach would be better to build a application?
First Approach: Building a application in a traditional way that is when we want data from database connect to database and fetch it. Second Approach: Another way is to build a web service/API and hit that endpoint and it returns data. I want to build both web and mobile application.So, I thought to build a web service/API and utilize it in web and mobile application. First of all,What I am telling is it correct? If Yes, Whether this approach is correct? Or I should build using first approach? Is there any advantage and disadvantages of both? -
