this is best channel that I found on youtube for django , I have never learned django so deeply . Others just teach how to write the code . I promise dennis this channel will grow by leaps and bounds . I am now literely addicted to watching the videos on this channel and reached till this video Thanku vry much
As far as I go deep within Dennis´ lessons, the more I learn. Haven´t ever found a so clear teacher about Django during my time of research in the net. Thanks a bunch man.
Really superb video with simple and understandable instructions. Previously, I was scared by another other tutorial video that I was unable to comprehend the simple concept. Great Work.
Thanks a lot. My signals were not working as I had installed my app using the app name only. But when I used the config file as you say the signal worked perfectly.

Your Videos give best explaination, Please make a clear cut series, in signals, celery and Django Channels for real time communication and their intergration in complex projects. It's a big request
Interesting. This is a topic I haven't looked into but its on my list now. I'll do some research and let you know. Thanks for the recommendation Dinesh :)
Awesome video, really simple explanation, I wanted to know if a signal can be triggered only if a specific value in a row has been updated, if so, how would one go about doing that.

How can i use this signal to keep history? For example, i have a table that have computer inventory records, i want to make Django keep the records of the data that was in that computer inventory table but move them to a new table created...making it keep a kind of history...please, how can i do that?
In my project i need something like that..if i save "A" model. Then "A" models imagefield will be automatically added to the "B" models imagefield..can i do it using signal?
can you please make another video on how can i get something like two or more foreign key to one model from deferent models. like; i have a model of countries. all countries. i have another model for states. but my third model is cities. the city has column of country id and state id. when creating a city, first i have to choose the country. then, state of the chosen country shall show up. and i could be able to chose state and finally add the city name. it would be much appreciated if you could light up on this.
@@prashantchanne2836 In your model Customer change method __str__,(self): return self.name, you must add in return "or 'some string'" e.g: return self.name or "empty name"
Why signals do not work because you need to register it. In order to register you need to update __init__.py file with default_app_config = 'app_name.apps.app_nameConfig' so you don't have to do it in settings.py ;)
I basically came to this video because I too didn't know about the work in apps config file. LOL And for one moment I thought that django doesn't work. Silly me :)
I am getting syntax error in the ready method. It worked in other project for me but I started a new project and it is giving me SyntaxError: Invalid Syntax. Everything is good I double checked.
Don't forget to check out my Complete Django course! dub.sh/NvGboTI
I've spent hours watching videos on signals to no avail. Dennis comes in and explains it in frickin' 13 minutes.

Great tutorial. The Django documentation was a bit vague, especially with tying in the signals within the ready() method. This got me up and running.
