what is the problem?

what is the problem?

Field "id" expected a number got <SimpleLazyObject>. This is the error I have been encountering for two days. No one can solved this error in my Django community. Please help me

Naggafin

can you give context surrounding this? my immediate impression at first is it sounds like you're using a value wrapped in gettext_lazy

부산

I delete database and all migrations even I created a new project and implemented that project as above it throw me this error too

부산

can you give context surrounding this? my immediate impression at first is it sounds like you're using a value wrapped in gettext_lazy

I did not use gettex_lazy anywhere?

Naggafin

are you using i18n and translations util functions in your codebase? if so, be careful about how these get applied to your models

Naggafin

I did not use gettex_lazy anywhere?

I see

부산

The project is not working even just I request the homepage also I am not able to enter the admin page

Naggafin

can you give more context exactly about what causes this error to happen?

부산

are you using i18n and translations util functions in your codebase? if so, be careful about how these get applied to your models

No

Naggafin

are you using view functions or classes?

부산

This is the Ecommerce project, this error taken place after implementing profile view.

Naggafin

well, let me back up. when you make an HTTP request to a view, does it happen then? or does it happen as soon as you start the django instance, i.e. with manage.py runserver?

부산

are you using view functions or classes?

Class based view like -> class Home(View): def get(self, request) ...

부산

well, let me back up. when you make an HTTP request to a view, does it happen then? or does it happen as soon as you start the django instance, i.e. with manage.py runserver?

No, it is happening when I request the home page but everything fine with runserver

Naggafin

so when you make a GET request to your HomeView, it happens?

부산

Please help me out. I almost have done the project but this error is stucking me. I can not throw this project because of I worked hardy on it

Naggafin

relax, software problems are always solvable. when there's a will, there is a way. we'll get to a solution

부산

so when you make a GET request to your HomeView, it happens?

Yes. In other word, the project is not working. You will get this error when you request the any View

Naggafin

I want to suggest an idea. have you tried placing breakpoint() at the beginning of a view's dispatch() method and then stepping through the code until you reach the point of error? i.e.: class MyView(View): def dispatch(self, *args, **kwargs): breakpoint() return super().dispatch(*args, **kwargs) ...

Naggafin

Yes. In other word, the project is not working. You will get this error when you request the any View

I would also review your middlewares. it sounds like that could be a potential failure point

부산

There is an interesting something that I did not implemented any view which are waiting for ID as described in the problem

Naggafin

There is an interesting something that I did not implemented any view which are waiting for ID as described in the problem

to determine the real cause of this, we absolutely need a traceback from that point

What is an breakpoint()? Where should I put it in my View?

부산

Can you review my project if you have time?

Naggafin

What is an breakpoint()? Where should I put it in my View?

breakpoint() initiates a pdb (python debugger) session. you can place it anywhere you like, but the most effective points are places in which you know precede failure points. when python hits a breakpoint(), execution stops and you're given control of the interpreter through the regular REPL; the same as if you did manage.py shell, except from that point with that application state breakpoint is a built-in function of python

Naggafin

Can you review my project if you have time?

yes. you can pm me parts of your code you would like me to review

Do you know of any similar library to control idle time in a django app and redirect to a specific url?

What do you exaclty mean by idle time?

Naggafin

my sentiment also

부산

yes. you can pm me parts of your code you would like me to review

Can I send my the pictures of My View to your direct?

Naggafin

Can I send my the pictures of My View to your direct?

yes, though I would prefer text because pictures are a pain in the ass

ROG 💻

What do you exaclty mean by idle time?

That the user has left the app open, that they are not doing anything and that x minutes have passed, then the app warns them first with a popup if they want to continue connected or not in the app

부산

yes, though I would prefer text because pictures are a pain in the ass

Okay I am sending them to you

Naggafin

That the user has left the app open, that they are not doing anything and that x minutes have passed, then the app warns them first with a popup if they want to continue connected or not in the app

I think django has a built in session timeout which you can fine tune to the account of seconds

Naggafin

obviously it doesn't communicate with the frontend though. but the way you solve that, I'd think, would be just to have a js timer popup after a certain time

Naggafin

so if your session timeout was 10 mins, maybe you'd make the popup show after 7. the session timeout on django resets with every HTTP request made for that session

ROG 💻

I think django has a built in session timeout which you can fine tune to the account of seconds

Yes, but that configuration does not indicate a popup or alert to the user that the session they have will be closed and that they make a redirect to the login url, for example.

Naggafin

Yes, but that configuration does not indicate a popup or alert to the user that the session they have will be closed and that they make a redirect to the login url, for example.

there is no way you can keep these in sync with django out of the box

Naggafin

but I don't think you need to

Naggafin

if someone loads a page, the session reset timer resets in django. so, on your frontend, make a timer that is slightly less than your django session timeout and have it reset on page load

ROG 💻

so if your session timeout was 10 mins, maybe you'd make the popup show after 7. the session timeout on django resets with every HTTP request made for that session

Naggafin

that way, they won't exactly be aligned, but it is "close enough" to be effectice

Naggafin

so if your session timeout was 10 mins, maybe you'd make the popup show after 7. the session timeout on django resets with every HTTP request made for that session

yes. you'd have to make the 'OK' button on the popup do some kind of AJAX request to the django server to reset the session though

ROG 💻

that way, they won't exactly be aligned, but it is "close enough" to be effectice

I understand, I'll try to investigate to see how I do it, I hope django introduces this feature in some update

Naggafin

I understand, I'll try to investigate to see how I do it, I hope django introduces this feature in some update

I'm not sure if django will ever natively support it out of box, mostly because it's outside the scope of the django project. you really need a web socket library to do this effective like django-channels

Naggafin

data between client and server was never meant to be in stateful sync in the HTTP model

Naggafin

web sockets alleviate this problem by providing stateful data

Naggafin

but for something so simple, doing this via web socket would be a massive unnecessary pain in the ass. you're better off just going with the happenstance approach: resetting the timer on client end and server end on every HTTP request

Naggafin

they're not technically aligned, but it works well enough to not notice

ROG 💻

yes it is a good alternative to work with web socket but I think I found something that could help, which is more or less what I was needing, the library seems interesting --> https://pypi.org/project/django-auto-logout/

Naggafin

oh wow. that looks like a nice little gem. every once in awhile you come across those really cool useful libraries like that that not many people have heard of before

Can someone plz suggest where i can host my DJango projects freely... thanks in advance

Can someone plz suggest where i can host my DJango projects freely... thanks in advance

render, railway, pythonanywhere. However, all of these have limitations to use for free that server. Once you have reached your limitation, you need to swtich your status to premimum, otherwise the server you are hosting does not serve to your Django app
