Why not use transactions in method save() ?

tfhx8
Here can collision

I am working on excel file uploaded from user form, modifying it using openpyxl lib.
After making changes, I want to convert file to pdf and export the file back to user. How can I achieve this?

You're already halfway there. Use openpyxl.utils.dataframe to organize your data. Then use reportlab library to generate a PDF

Thanks Eric but I can't understand utils.dataframe.
Where do I need to save the file to use it for reportlab conversion?
Cesar

You could use tempfile library to create a temporary file

I guess you have studied Python with google, is it hard to find a tutorial for Django?

I am really confused about images. How do I display an image with img src without storing it or creating a static folder

Use some image url stored somewhere into the web world 🤷🏻♂️

Use something like imgur or you can host images in CDN or Amazon s3

CDN ( Cloudfront ) can be used with S3 too ☺️

However I have never used a CDN or sperate storage myself 🤔

how to open static pdf files in templates

hello, this may be a very newbie question
I have a cookiecutter-django project
I want to get the base URL in Python code, so that if the url is
http://myweb.domain.com:8000/admin/anything
I want to get
http://myweb.domain.com:8000
preferably without a trailing slash ('/') at the end as shown
I googled and found a get_current_site in django.contribs, but I think it goes to the database
Is there any way to retrieve this base URL for saving it in a variable in my settings? Is get_current_site and the database the only way to go to do this (other than hardcoding or environment variables)?

Put your domain into a settings variable
Then you can use it whenever u want
Martín
aham
Martín
I'm going to make my first django/heroku deployment
Mirco
Doesn't care the platform
Martín
so I don't know which is going to be the domain yet
Mirco
Yup u know
Martín
so I think an environment variable should be the way
Martín
ok, I'm trying and asking if any trouble shows up
Martín
thanks

hi again
is there some way to get the current scheme being used? so that I know if the web is http or https?
Mirco

Yes, but why ?
On prod you must use https
Martín
but I want to write code which works locally and in production
Mirco
For doing what ? Maybe there's an easy way instead of checking protocol
Martín
well, I'm using the base URL of the web to access an chrooted SFTP
so if I add /some/directories/ to the URL, after some checks it accesses /some/directories in the SFTP
Martín
until now I had in the base.py a SERVER_URL variable
Martín
hardcoded
Martín
but I'm changing precisely that
Batman
until now I had in the base.py a SERVER_URL variable
is that to allow your app to be run on that particular domain only?
Martín
I could hardcode https in production.py and http in local.py
Mirco
I could hardcode https in production.py and http in local.py
Why do you wanna hardcode it ?
Django has lots of settings needed to be set when you go on production and of course even the ones related to https
Mirco
If you run manage.py check --deploy you will see the list of them
Martín
is that to allow your app to be run on that particular domain only?
idk if I understand you
the SERVER_URL is the
http[s]://myweb.mydomain.com[:port]
string I'm using all the time to build the new url to go to
Batman
Why do you wanna hardcode it ?
Django has lots of settings needed to be set when you go on production and of course even the ones related to https
setting SECURE_SSL_REDIRECT to True in your settings file would be the one precisely
Martín

no, I want to do the opposite of hardcoding, remember that the question was how could I know the scheme between http and https
Mirco
no, I want to do the opposite of hardcoding, remember that the question was how could I know the scheme between http and https
Yup and I told u there's better way to do that instead of fill code of many if blocks about request scheme
Batman
no, I want to do the opposite of hardcoding, remember that the question was how could I know the scheme between http and https
depends on where do u want to access it? if if it's within the template there's a way to do it
Mirco
Just read Django docs about going on prod
Martín
Mirco
You will.find lots of answers
Martín
ok, I'm googling
