Python Django Rest - Return extra field with lowest, highest and average values of some other field
I'm new to Django and APIs in general and I want to create a Django based API using Django Rest Framework.

Connectivity issues to Sybase database as a secondary database with Django
I can connect to sybase database with FreeTDS and pyodbc as follows: # hello_sybase.py import pyodbc try: con = pyodbc.connect('Driver={FreeTDS};' 'Server=10.60.1.6,2638;' 'Database=blabla;' 'uid=blabla;pwd=blabla') cur = con.cursor() cur.execute("Select * from Test") for row in cur.fetchall(): print (row) cur.close() con.close() except Exception as e: print(str(e)) I tried to connect in a django view as follows: import pyodbc CONN_STRING = 'Driver={FreeTDS};Server=10.60.1.6,2638;Database=blabla;uid=blabla;pwd=blabla' def my_view(request): with pyodbc.connect(CONN_STRING) as conn: cur = conn.cursor() cur.execute('SELECT * FROM test') rows = list(cur.fetchall()) return render(request, 'my_template.html', {'rows': rows}) When I run python manage.py runserver and run the code in the above view.

isADirectoryError [Errno 21] while trying to render custom select form field
I am working with Python framework Django v2.2. I am trying to add custom attributes to <option> elements so that they are constructed as <option ext='xx'>.

Django view not rendering - sidebar & header loads fine but main content does not load
I've been through so many different things and I just can't work it out; need a fresh set of eyes haha My view does not render and this seems to be the case across my apps and landing page - the sidebar and header loads fine, footer looks to partially load but I believe this is due to the fact the main content does not load.

Django db_router does not exclude app models as expected
I am trying to create an application where one server communicates with many other worker servers. Those servers will each have their own DB which should only contain the tables for their own models.

How to get users spent time on a task with Djanog?
I have Django project and several views. In one view i want to track users spent time. How can i do that? Maybe some libraries or django built in methods?

Then page reloads with new photoes and task is similar, find similar photoes and submit. I need to track and store that time what each user spent on this task. If i check users time when he open view i don't know when she close it, and also user can just open view and chill, without doing something. How or with i can realize it? -
How do I include a Django project's README.md in a template?
I want to add the text of the readme to a custom index template in admin. So I have the following relevant paths in the project: ./README.md ./impact_api/templates/admin/index.html And in the project settings I have TEMPLATES = [ { 'DIRS': [BASE_DIR / 'templates'], ...}] So in the index.html file I want to do something like this: {% include "../../README.md" %} But that raises an error: TemplateSyntaxError at /admin/ The relative path '"../../README.md"' points outside the file hierarchy that template 'admin/index.html' is in. The only things I can think of are a) to move the README into the body, which I'm not sure I can do without losing the display on Github and seems like a bad idea even if I can, or to change the templates lookup path to the entire project, which also seems like a terrible idea. Is there a more sensible option? -

Django Bootstrap 5 - Custom styling
I am using django-bootstrap5 in a Django project. According to the docs, for customization, I can add the following to settings.py: BOOTSTRAP5 = { "css_url": {}, # I could add a custom URL here "theme_url": "..." # Or I could override the theme here } Which seems overkill for only a few customizations. How can I customize something like the primary colour of Bootstrap? Do I have to use Sass/Scss, and if so, how does one do this in Django? -

How to deploy Django Based Server and Laravel Project Simultaneously on a Single Droplet
