I'm using Django to build my own blog now and I think it's good. But now I've noticed a problem. When I change the DEBUG const to False, System checks are OK but It'll return a 500 error status. When I change it to True,The bug won't happen again. So what's the problem? Can anybody help me?

Good afternoon,
I am currently developing a Flask application, and I am experiencing an error that had never happened to me before. I am currently setting up a dynamic route in Flask. This is the piece of code:
#app.route('/viewcar/<string:carId>')
def viewcar(carId):
print(carId)
car = Car.getCarById(carId)
return render_template("car.html", car=car)
However, when I pass any variable to the URL (let's say "http://127.0.0.1:5000/viewcar/4975facbbce511b65e14f44719340029-cf161184-91fc"), when I check the output in the console, it says that carId equals to favicon.ico instead of "4975facbbce511b65e14f44719340029-cf161184-91fc". Any ideas on what could this be? It has never happened to me before. Thanks in advance.
I just ran into this issue today too, however I noticed that when I launch my development flask server at http://127.0.0.1:5000/ in Chrome (version 104.0.5112.101), the console logs show that it grabbed favicon.ico for the variable I was grabbing from the URL, but when I used Safari (version 15.3) the URL variable was correctly parsed.
Now I'm starting to think it's a browser related?
I'm really new to flask myself and also came across this issue. For me it was that I had another route in my module that got executed prior to this route I intended and the variable name was being assigned there so it seems the next (default?) argument must have been used in my intended route. I'm sure I'm only describing this halfway correct but hopefully it helps somebody debug their issue a little quicker.
I am trying to view a Couchdb database in the browser named event_db. However, when I navigate to the following url: http://localhost:5984/_utils/database.html?event_db I get the an Error: not found missing and my url automatically redirects to http://localhost:5984/_utils/database.html?event_db/_changes.
This problem seemed to occur after I added _changes to the url and created a script checking the database for change here: couchdb-python change notifications
Has anyone ever experienced this problem? If so, how would I fix it?
My apologies I am new to Couchdb.
Thank you for your help,
Brian
Turns out I needed to clear my cache in my browser. After I did this, I was able to successfully navigate to the event_db.
I am trying to make sure that my site is properly protected from showing the details of the error in production.
I've been struggling with this for a while, as at beginning I understood that in order to avoid Django from showing the error (module, line of code, etc.) all that was needed was changing DEBUG from True to False in settings.py.
However, I realized that Django was still showing error details, so investigating a bit more and I came to know that the following was also needed:
TEMPLATE_DEBUG = DEBUG in settings.py
404.html and 500.htmlinside the templates folder
Is there anything else needed to make sure that the user does not get those messages?
And how does Django deal with the other kind of errors, like 400? I saw here that there are handlers for 400 and 403, but I do not understand it and I don't know if they are needed at all for a basic using case.
If DEBUG is False, Django doesn't show error details to the user. If it did in your case, the most likely explanations are either that it's not using the settings.py file you think it's using (in which case you should check the Python path, the directory from which you run manage.py, and the value of DJANGO_SETTINGS_MODULE), or that you did not restart Gunicorn/uWSGI/Apache after you made the change to settings.py (Django does not restart itself automatically in production like it does in development).
As for 400 and 403, just leave the Django defaults. If Django receives a bad request (unlikely in production, because this will usually be caught by Apache or nginx), it will call bad_request() which will just show a "400 bad request" to the user. Likewise for other errors.
I went into settings.py in the Django Framework for my site because I had run into a 500 Internal Server Error. I'd heard that this happens when DEBUG = False, however, my DEBUG is set to True and it still does not give me anything more specific than a 500 Internal Server Error.
My site was running perfectly fine and all of a sudden this error occurred...any thoughts?? I checked my wsgi link and nothing had changed there as well!
I am trying to deploy my first app with heroku, and I keep running into issues. Essentially, now whenever I try to open my app with heroku open, I get the "Application Error" page telling me to check my logs. I successfully was able to get through the tutorial, but now following the same steps with my own project, I haven't had any luck. As far as I can tell from the logs, the relevant warnings I am getting are:
WARNING/MainProcess] celery#ce7e5946-3bc3-4622-856f-863b49f442d4 ready
WARNING/Beat] Reset: Account for new version field
WARNING/Beat] Reset: Account for utc_enabled field
WARNING/Beat] Reset: Account for new tz field
The last three all seem to stem from the PersistentScheluler class within celery/beat.py, but I don't understand why. I have no idea about the first warning (or why that is even a warning). Any insight? Thanks in advance for the help.
have you tried to set DEBUG to True in Django settings ?
that should give you enough information about the error to fix it.
