Value changed in creating observer is not saved in the database

[JRubics]

Hi, I am using observer like this:

class WebsiteObserver:
    def creating(self, website):
        website.app_name = new_name()

Website.observe(WebsiteObserver())

but after I do:

website = Website()
...
website.save()

observer is called, but value is not saved in the database. If I try to call website.get_raw_attribute('app_name') after save() I get the new value, but just website.app_name returns the old one.

Expected behavior
I think it should change value to the new one, but please check if I am doing something wrong.

cannot replicate this behavior. Could you give some more detail? what is the value of new_name()?

Heres what i tried to replicate:

1. observer:

2. Code

3. Result

Looks like its working. It's also working if i don't set the name, its also working if i use the create method.

Can you tell me what else is missing that i haven't tried here?

I realized I am using with DB.transaction(): and that's why just website.app_name is not working until transaction get executed. Sorry, my bad 😞

I still can't make it work even after the transaction. Transaction looks like this:

I'm updating vhost after save() because it depends on new app_name value. After this, in the database app_name still has old value.

I managed to solve it doing this:

but I don't think it is the right way. Do you know what am I doing wrong?

One more note: new_name() is making a query to the database to check if name already exists. If it does, it adds suffix to the name. I'm not sure if that query has something to do with the transaction?

And thank you a lot for helping here 🙏

hmm possibly. This is deff more good information so I'll go back and see if I can replicate this
