downloading image files from django template

[Teaching Tech]

How can I download an image file that is shown to the template in Django? 
I'm new to Django. This might be a silly question. But I need to know for 
my existing project.

Shell script dynamic execution from app

[ashish goyal]

Hi guys, i have built an app for collecting various stats of environment. Its 
working.
Now i wanted to integrate it with all the utilities or shell scripts which are 
present on application server. So its like all scripts names as a list on 
django app and one click run pf those script. Currently those scripts are 
scheduled with control-m. I wanted to have a dynamic design of those scripts so 
that this all could be possible. Any leads?

Thanks
Ashish

Re: help with my api and JWT

[Robson Andrade]

Hello friend,

I noticed that you are using the standard token authentication system. 
However, this method does not correspond to JWT.

Since you want to use authentication through JWT with DRF, you must use:

1) A JWT library that implements this type of authentication which helps 
you to create a login route to obtain the access token, route to the 
refresh token, or other routes and resources you need. I can recommend you: 
Simple JWT (my favorite) 
https://github.com/SimpleJWT/django-rest-framework-simplejwt or REST 
framework JWT Auth - https://jpadilla.github.io/django-rest-framework-jwt /

2) Next, you must correctly configure these Django modules.

3) When everything is properly configured, you must first obtain the access 
token and refresh token through a previously created user login.

4) Once you have the access token, you must send it to the request head as 
follows, for example:
 {Authorization: "Bearer 
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImV4cCI6MTU5NTYwMzIyNSwianRpIjoiY2QxYTRiYWJiZTgzNDVhMjlkMGJmYTIzNTc0Zjk0ZjEiLCJ1c2VyX2lkIjo4fQ.i6bmtiqFyWyxo7mMuZxQjN9RvM-DjaiOwRVxeRBdiwM"}

5) Every 5 minutes you must request a new access token through the refresh 
token, but now in the body of the request:
 { "Refresh", 
"ppADdAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImV4cCI6MTU5NTYwMzIyNSwianRpIjoiY2QxYTRiYWJiZTgzNDVhMjlkMGJmYTIzNTc0Zjk0ZjEiLCJ1c2VyX2lkIjo4fQ.i6bmtiqFyWyxo7mMuZxQjN9RvM-DjaiOwRVxeRBccdSA"}

Read this article: 
https://simpleisbetterthancomplex.com/tutorial/2018/12/19/how-to-use-jwt-authentication-with-django-rest-framework.html

Hope this helps!

See you later!

Re: Import csv file on django view

[Naresh Jonnala]

Hi,

I am not sure this will help or not, Still i want add a peace of code.

sniffer = csv.Sniffer()
dialect = sniffer.sniff()

dialect.__dict__
mappingproxy({'__module__': 'csv', '_name': 'sniffed', 'lineterminator': '\r\n',
'quoting': 0, '__doc__': None, 'doublequote': False, 'delimiter': ',',
'quotechar': '"', 'skipinitialspace': False})


lineterminator = dialect.lineterminator
quoting = dialect.quoting
doublequote = dialect.doublequote
delimiter = dialect.delimiter
quotechar = dialect.quotechar
skipinitialspace = dialect.skipinitialspace


csv.DictReader(self.file_open, **dialect)


Try this.

Re: Error in sending mail

[MUGOYA DIHFAHSIH]

i think it is repeating it cos the email you put in the settings.py is the
same email you used for clients to send to contact you through.
What i mean is a person contacting you sends the email to
rubymoti...@gmail.com and it is the same email you used i the settings.py
to permit django app send email.
