How to send image as part of email body in django
I am building a portal for sending dynamic emails. Part of the form is an image field which the user can upload an image which I would like to be rendered in the image body, not as an attachment after the form is filled out.

module 'hello_world' not found while running the manage.py runserver in django
My site is hosted at centos 7, lamp stack, whm/cpanel. I created a virtual environment mp_env and installed python3.7 and Django in mp_env. This mp_env is created in the same folder where we have public_html folder for main site. In this mp_env folder we have bin and lib. Python3.7 is installed this lib folder and Django was installed in site-packages of this lib. No. I did not do that intentionally. I just installed python and Django in mp-env. They automatically found places. Then I created a project myproject. I could test it with ./manage.py runserver 0.0.0.0:8000. I could change the database to mysql, create users and login to admin from web browser. It was working fine.The project folder is outsite the mp_env. Then I created an app hello_word inside the project directory myproject using this example at https://realpython.com/get-started-with-django-1/ I have followed the steps mentioned there and used everything word by word. Now when I try ./manage.py runserver 0.0.0.0:8000, it gives error - module 'hello_world' could not be found. -

Pytest django url's tests
I saw some people writing url's test like this: def test_sample_url(): path = reverse('url_name', kwargs={'pk': 1}) assert resolve(path).view_name == 'url_name' As for me this test is not checking anything, because if I place 'url_name' in second line then in third it is obviously going to be equal to it.

How to hide certain json data from passing through if it doesn't meet a condition in Django rest framework?

In Django is it possible to send data from a view to itself when a page is refreshed
Is there a way to know which buttons are pressed in a page when returning to a view in Django? I am trying to implement a filter on a list of values in a Django app. The page has a list of checkboxes and 3 buttons to decide which values to show in the list. For example: a list will consist of values: db-productA-1, db-productA-2, db-productB-1, db-productB-2 and db-productC-1, db-productC-2 and the buttons will be: ProductA, ProductB, ProductC When the page is loaded for the 1st time, all buttons are un-pressed and all 6 dbs are listed. I then press button ProductA to filter the list. Pressing the button runs the view and I want to know which buttons were pressed, so I can decide which values to list. If I continue and press ProductB, I'd like to know that both buttons were pressed. Is there a way to retrieve the state of the elements in the page in Django? -
Django login.html and base_generic.html locations
According to: https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Authentication and https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Home_page the base_generic.html file should be included in /locallibrary/catalog/templates/ (inside the application folder), but the login.html file should be included in /locallibrary/templates/registration/ (at project root directory level) The login.html use the base_generic.html to extend its code. It is strange (from my beginner point of view), to have the templates base folder "more inside" than the login one. What if we had other applications with different base files? Which base file would the login registration file extend in that case? locallibrary/ # Website folder manage.py # Script to run Django tools for this project (created using django-admin) locallibrary/ # Website/project folder (created using django-admin) catalog/ # Application folder (created using manage.py) templates/ # Application templates folder base_generic.html templates/ # Templates folder registration/ # Registration folder login.html -
