Good day all, am facing issues, when user uploads image, if the image is heavy the site becomes slow, please what do i do

Make them lower resolution or higher compressed

Make them lower resolution or higher compressed

how do i do that,any library or guide

Well just think logically. What is the range of sizes of your images?

Does the user store images on the server?

Do you need them to be high resolution?

You could compress yourself the images or load them after page load or only when they are shown on the body. Depends on your webpage. What do you need.

i get this, i need a solution to compress image before upload

You could make the browser do the operation, or the server. Depends on the capacity of your devices and the cost.

Also check what image quality do you need to store.

ok,thanks

I think using client side operation (JavaScript) will save you server cpu load and site performance should be better. Sorry for my grammar. I speak spanish...

Nice one...

Noo i was reading 📖 🤔

hmm me too 😕

but talking about model managers, can’t you just inherit from modelmanager or is there something i’m missing ? That’s not related to api or rest framework no?

Ok, guys. I decided to create a model manager for a main model in my scheme and create related instances there. And just keep it simple...

Thanks for your time and help

Anders (izznogooood) 🇳🇴: Have any of you guys tried "editors" like pigendo and bootstrap studio? (in relation to Django / flask) what's your experience and can you recommend it to someone less experienced (but basic understanding) with bootstrap / html and css.

Dear members, When testing Django in jmeter (nginx+gunicorn+django), we got only 150 concurrent users, after that the request fails. Can you give any suggesion to improve the scalability (8 GB RAM , 4 cores, 250 SSD)

Did you check the Nginx setup? No limitations from Nginx? Workers. etc..?

Try to test each service involved. Ex: Create a static file and test how request Nginx can handdle when you download these file. If Nginx it's not the problem, keep testing all other services.

Hi guys! I have a little problem: I wrote a managers.py to declare my customized managers and it imports from models.py Also I have my models.py that imports my custom managers from managers.py This give multimple errors... I think this circular dependency is breaking my code. Should I remove the file managers.py and put my custom managers on models.py ??

Put your managers into models

Thanks @iFlare3G !!

Can someone help me? I can not add instances of a template with ForeignKey

Share the code

I have a Post class with author, title etc .... And I have a Comment class, which has a fk_post field, to use the same id of the related Post object. When I try to add a comment related to this post, for example: >>> from blog.models import Post, Comment >>> new_commet = Comment(fk_post=3, comment="text here", author="i") django return this error: ValueError: Cannot assign "3": "Comment.fk_post" must be a "Post" instance.

I did not quite understand what I should do when I see at this error

in the admin panel of Django, I add a comment using those same values

OK, I got it

"Comment.fk_post" must be a "Post" instance.

You are using number 3 as "Comment.fk_post"

You should use an instance of Post class

You are using number 3 as "Comment.fk_post"

Pass instance

Not just int

Show the ORM query

@marcoscoder

And the model

how to do it?

I'm sending to the pastebin

Fk_post must be some foreign key I suppose

models: https://pastebin.com/3NCb1MaW

@marcoscoder when you define a foreignkey field you should handle these field as an instance of the referenced model (not as int)

Something like this post_instance = Post.objects.get(id=3)

>>> post_related = Post.objects.get(pk=4) >>> new_comment = Comment(fk_post=post_related, comment="new comment.....", author="my name")

ohhhhhh

Should have pasted the whole models file

>>> post_related = Post.objects.get(pk=4) >>> new_comment = Comment(fk_post=post_related, comment="new comment.....", author="my name")

It should work

I will try to add through a view that I created

I will try to add through a view that I created

keep in mind you should use an instance of post class and it will work :)

Hahahahhahaa

basically this. I managed to do what I wanted, but not in the right way

But, this is the way DJango handles foreignkey fields. It isn't a "gambiarra".
