Django debugging with Eclipse and PyDev - python

I just managed to get debugging my django site 'kind of' working in Eclipse. All my breakpoints get caught just fine, but I have to restart the server every time I make a code change. I think this is because I'm using the --noreload argument when kicking off the server.
Is there any way to setup Eclipse debugging so that I can change code, and continue execution, with my changes being reflected in the django site straight away?
Cheers,

This is a bit late, but in case someone else comes looking for a solution to the same problem:
This video was very helpful when I was trying to setup Django Eclipse debugging with autoreload i.e. without using the --noreload switch. It pretty much walks you through the steps with a couple of helpful pointers. I've set up twice myself using this video.
The manage.py replacement code can be obtained from http://djangosnippets.org/snippets/1561/
I found these links through the poster's blog post which seems to be down at the moment, hence the direct links
EDIT: A patch may be required to Django 1.3 to run in autoreload mode from inside an IDE. See PyCharm manage.py runserver error for more information.

Author explains how to do so here, basically you have to embed the remote debugger into your manage.py file.
Hope this helps

PyCharm 2022.1.2 does not hit the debug breakpoint with Django

I can't get Python debugger to work on PyCharm 2022.1.2 with Django 4.
When I set the breakpoint inside the view function and then call this view in the browser, nothing happens when started in debug mode...
breakpoint_selected
However breakpoint is hit when I set it for import.
breakpoint_hit
I have 2 configurations, one for Python and one for Django Server, both don't work.
config1
config2
Went through numerous JetBrains tickets with people reporting similar problem but didn't find the solution there. Also tried creating second run configuration, for Python instead Django Server, but this also didn't help.
Solved this by deleting the .idea directory from top-level django project dir. Not sure what were the mechanics behind it, but it worked and now breakpoints work perfectly.

Profiling Django with PyCharm

My app is pretty slow even in a dev environment so I would like to figure out what's slowing it down so I can try and fix it.
I know about the debug toolbar and according to what it reports neither the database queries nor the downloaded sources are the issue, so it must be the business logic.
However, I cannot run the PyCharm profiler with the Django server because, well, it's not like running a script.
How may I profile Django with PyCharm?
You should probably set configuration properly.
Then click on Edit Configurations...
The main thing is to set Interpreter (your virtual environment). You don't have to set Custom Run Command if you use python manage.py runserver
Then you can run Django server directly from PyCharm ann Profiler too.

Is there pluggable online python console?

I'm thinking if there already is some sort of online live python console (web-based) with open source code available. Anyone know of anything?
It would be really useful to have console in Django admin (like running python manage.py shell on the server's terminal), so it would be great to have django/any wsgi aplication, that can be used to enable web based live console access.
Thanks
You're looking for the Werkzug debugger.
http://werkzeug.pocoo.org/
http://werkzeug.pocoo.org/docs/debug/
It's got an interactive javascript based in-browser debugger for your WSGI projects, among many other great tools. Fantastic stuff.
For Django specifically, there's also RunServerPlus, which is part of the django-extensions package.
https://github.com/django-extensions/django-extensions
You should check out Python Anywhere. You can run python web apps, you get an SQL database, and you get a bash shell in your browser.
Have a look at python shell from Google. There's a link to source code at the top. Loading Django environment into it might be not very easy but I believe it's possible.
I'm not sure if this meets your desire but you might take a look at Chrome extension : https://chrome.google.com/webstore/detail/gdiimmpmdoofmahingpgabiikimjgcia
There is a great website called Codecademy. It teaches the fundamentals of Python, Ruby, Javascript, and HTML/CSS.
They also have online consoles for each of the languages they teach, excluding HTML/CSS. This website is Codecademy Labs. Codecademy Labs has a console you can type directly in, and an editor that displays output in the console. I hope that this helped you find what you were looking for!

Installing django on dreamhost (help a newb out)

I'm trying to get django running on my dreahost account. I've been trying to sort of use two tutorials at once: the one on the dreamhost wiki and the one in the django book.
I installed django using the script on the wiki page, but I ran into trouble immediately while trying to work through the django book. It says:
To start the server, change into your project directory (cd mysite), if you haven’t already, and run this command:
python manage.py runserver
This launches the server locally, on port 8000, accessible only to connections from your own computer. Now that it’s running, visit 127.0.0.1:8000 with your Web browser. You’ll see a “Welcome to Django” page shaded in a pleasant pastel blue. It worked!
Those instructions seem to assume that you're developing locally, not on a shared server. Where the heck am I supposed to look for the "Welcome to Django" page after starting the server? In my webroot? No dice.
Anyway, I tried to blunder ahead through the django book to its hello world tutorial (chapter 3). But once I've edited the view file and the URLconf, I don't get a nice clean "hello world" text. Instead (as you can see) I get an "import error".
Any help would be greatly appreciated.
Don't try and learn Django via your server. Install it on your local computer, learn how it works, develop your project, and then install it on Dreamhost.
Your project assumes that 1) your app is called "mysite", and 2) mysite is a package, e.g. mysite/__init__.py exists. If either of those are false then correct your code and/or file structure.
This is an old post and am sure you have found the answer by now. I have solved this problem by using the command
python manage.py runserver mydomain.com:8080

problems doing the Django tutorial on Dreamhost using Passengers

I have looked and I could not find this question before, and it surprises me.
I am reasonably proficient in Python, and I used Dreamhost for a number of years. Now I would like to learn Django. They are finally supporting it using Passenger. Which I do not know what is.
Following the instructions on Dreamhost I installed Django. Then I started following the tutorial 01. This went well, except that I could not start the server (this in the tutorial) since the code was live on dreamhost. At the time this did not seem to make any difference. Then when I went on the second part of the tutorial I had to access the admin site. And it worked well going to myurl/admin/ , as it should. But here the problems started. According to the tutorial (here) I have to add a file in the poll application and then restart the server. But I never started the server in the first place, my code is running live on the web... but when I add a file the website the admin acts as if it does not see it.
Probably dreamhost has started its own server, and I don't know how to restart it. But I assume this is going to be a common problem when you run django on dreamhost. Every time you add a file you will have to tell the server to consider it.
So what should I do to let the server know about it?
Thanks,
Pietro
Here's the relevant section of the Passenger user's guide for restarting Passenger:
http://www.modrails.com/documentation/Users%20guide.html#_redeploying_restarting_the_ruby_on_rails_application
Eventually I got the answer from the DH support service. They told me to
pkill python
I did it. I also checked with
ps -aux
what process I was running. And indeed I could see the python process starting when I went to the page, and being killed when I pkilled it.
Thanks for all that helped.
I had the same problem with Passenger not reloading the Django server.
According to Django wiki page on Dreamhost, you can touch a "restart.txt" file that Passenger watches. If the timestamp on the file changes, Passenger restarts Django.
If you modified your application and your changes do not seem to be reflected, you may need to notify Passenger about your change by creating or modifying ~/example.com/tmp/restart.txt:
touch /home/user/example.com/tmp/restart.txt
Source: http://wiki.dreamhost.com/Django#Hints
For the tutorial, you should be working on a local machine, not a web server.
