It's my second day of Django and everything seems to be going petty well. Though the installation process is a bit longer, I still find it friendly to get started with. I am currently learning how to pass data to static file from views.py. The problem I am having is that it is only showing the previous changes not the recent. I have hard-refresh but still not working. I don't know how to stop and rerun the server because I don't know how to combine both Ctr + BREAK.
Ctrl + break mean pressing ctrl and alphabet c key at same time it will break the server and if you want to rerun it run the command
python manage.py runserver
There may be issue that you won't Saving your work other then this try force reload CSS file by pressing ctrl+ f5 in browser tab in which Django project is running.It might be helpful.

In order to print stuff on campus, I need to login to the webpage and submit the printing job manually on a browser, but I wanted to submit a job locally. So I wrote a small python script that uses Selenium to automate print job submission. I've verified that it works, but there's one thing that bugs me. Even after I select a file to print, the file dialog stays there until the actual code runs to the end.
The structure of the code is like the following.
1. Enter information on terminal (username, pw, which printer to use, how many copies, etc.).
2. Call tkinter.Tk().withdraw() to select a file (after selecting a file, "Submitting a print job..." is printed, as shown on the screenshot)
3. Do the actual Selenium job using information I collected above to submit a job
How can I make that file dialog disappear as soon as I select the file? Is it an ascyncio problem?
I noticed that many other people were experiencing a similar issue. While many had solved the issue by adding Tk().update() before or after askopenfilename() line, my problem was only gone when Tk().update() line was added both before and after the askopenfilename() line. FYI, I'm running the script on macOS with python 3.7.
This answer on Stack Overflow offers a solution I am trying to implement. In particular, see the sections "Installation Instructions" and "How to Use".
Can anyone tell me the steps required to "restart" IDLE?
New Information:
Just as people have suggested I thought this simply meant closing the program and opening it back up again...but I already tried that.
The other twist to my situation is that I'm working on a virtual machine so I was unable to do the installation of IDLE2HTML.py myself. My work's Help Desk had to do it so I cannot speak for the accuracy of their work. For now I'm assuming they did it correctly, but when I go to the "Options" menu there is no option to "Save as HTML".
My only guess at this point is that I still need to "restart IDLE".
Just wanted to double check if there was something else I could do before going back to my Help Desk department.
IDLE reads the idlelib/config-xyz.def files, including config-extensions.def, just once, when it starts. So any changes to config-extensions.def only takes effect the next time you start IDLE.
If you do not see 'Save as HTML' after starting IDLE, the extension is not installed properly.
It means you need to close the IDLE so that any changes made by the script can affect the IDLE
Simply close the IDLE either via the X, Ctrl+Q or File>Exit, then open the IDLE again.
If you are using idlelib module from a Python program then close your program and run it again.
I want to change my models in django
when I execute python manage.py makemigrations ,it asks a question:
Did you rename the demoapp.Myblog model to Blog? [y/N] y^M^M^M
that I input y and press Enter,but it adds ^M to the line
I've looked around and apparently but I've got no choices
can anybody tell me how to fix it?
Better to reset the console frequently.
This is not a big problem but due to multiple terminals being not reset for long durations, such problem occurs.
Apparently, this may happen if your terminal isn't configured correctly, and incorrectly interprets newlines. If you're not running on ubuntu, google for the operating system and/or terminal application you're using, with the term ctrl+m. ^ is often displayed when you press control and some key. I'm not sure about the technical details, buy I often see ^c after stopping an application with CTRL+c.
since yesterday PyCharm 2016.3 won't accept selected lines from the list of code completion:
If I hit enter, a new line will be set into the editor rather than the selected line of the popup window. Is there any setting for this behaviour? Until now I couldn't find anything.
I noticed on a few occasions the GUI going somehow off-rails, including in ways similar to the one described. I couldn't determine a pattern in the occurences. Just closing and re-opening the project didn't always help.
What worked pretty reliably for me in the end was exiting PyCharm (giving it ample time to finish), making sure no related java processes remains active (running on Linux, in some cases I had to manually kill such processes when it became clear they're not going away by themselves) and then re-starting the IDE.
I found the current keymap for code completion by chance. This is set via:
Settings > Keymap > Code > Completion > Basic
I've got 2 problems with Eric4 IDE.
Can't find an option in preferences to autosave my changed files before running script. It's very annoying that I have to save my file and then run script.
Second problem is running a script. I can't find any button to run a script/project instantly. 'Run Script' button always opens a setting window.
One way to get around this, as it seems there is no built in way is to bind a key to save the file (ctrl+s), then run the script (F2), and finally hit enter (to close the settings window and run the code).
This bothered me a lot too, and I know this is 2 years late but it might help some else who comes here looking for this very solution, like I did. Here are the actual answers, ERIC v4.4:
Press F4 instead of F2.
The first time you have to use F2 to 'Start' the script, so dismiss the settings window. After that you can use F4 'Restart' and it will run with the settings you chose initially.
The Autosave option is well hidden unfortunately:
Settings-->Preferences-->Debugger-->General-->!Scroll down to!-->Start Debugging-->Autosave changed scripts
And you were spot on - these two things do have a huge impact on productivity.
