Pythonanywhere issue #288

Closed duskmaiden18 closed 3 years ago

duskmaiden18 commented 4 years ago

Hello. I have deployed my py4web app on the Pythonanywhere, and I have some problems with registration. When I want to register, nothing happens and this error appears in the console. What can be wrong? I also deployed myfeed app and there is the same problem. Capture

mdipierro commented 4 years ago

Sorry. Not enough information.

Can you check for logs on python anywhere? What py4web version? Is this on first installation or after upgrade ot py4web?

Well, I think that problem is not in the Pythoanywhere. It is most likely appeared because of versions mismatch, because previosly I didnt check it at my localhost. I have download the newest version of py4web from github to my computer, then insert to path "apps" my app, that has version py4web==0.1.20200202.1, and registration doesnt also work on my localhost(401 error). How can I solve it?

Hi,

your description is not so clear for me ... How have you installed py4web on Pythonanywhere? There is a detailed tutorial here https://github.com/tomcam/py4webcasts/blob/master/docs/how-install-source-pythonanywhere.md (thank you, Tom). How have you installed py4web on your computer? The official instructions are here https://py4web.com/_documentation/static/index.html#chapter-01. What's its OS?

Also, it's not a good habit to copy pieces of python programs to different systems. They could contain compiled objects that are not compatible with different OS or different python versions.

Probably the simplest solution is to start from scratch....

I start my app from scratch and registration works at localhost. Then I deployed it to pythonanywhere using tutorial that you gave me. And registration works only when "VERIFY_EMAIL" is False. When I change it to True, and try to register, in the DevTool in the Network tab appears a registration request that is pending, and then 504 error(gateway time-out). Capture1 Capture3 Here my setting for verifying email: Capture2 Also I allowed (in the account settings) external apps to use my gmail account

Hi,

did you ever succeed in sending SMTP emails from Pythonanywhere? It could be that Google is blocking your attempt for security reason.

Test it with a Bash prompt in Pythonanywere. Follow this post for connecting to port 587 directly with TLS. If you've got "Username and Password not accepted. " it means that you need to enable "Access for less secure apps" in your Google account (which seems you've already done). I was getting the "Please log in via your web browser and then try again." until I visit this page for unlocking it http://www.google.com/accounts/DisplayUnlockCaptcha. See here for more details. NOTE: if you use the same browser with multiple Google accounts be careful to use a new incognito session with the account used to send SMTP, otherwise the last setting could be applied to another account.

If you' are able to send SMTP mail from Pythonanywhere, we'll have to look to py4web ...

mdipierro commented 4 years ago

That may require a paying account from pythonanywhere.

I'm quite sure I can send Google SMTP email using command line from a free PythonAnywhere account ;-)

mdipierro commented 4 years ago

My understanding is that free accounts do not allow outbound connections. Maybe there are exceptions.

I did what you say, here is screenshot that SMTP emails work(I have recieved mail from strahovka.work2020@gmail.com on zikzak200015@gmail.com) SMTP

Then I re-run py4web apps, reload site and registration stiil not working(

I just find out another problem with SMTP on my website. I have ajax on the page, it call function from controllers.py. This is code of the function:

@action("static/add_company", method="POST") @action.uses("add_company.html", db) def add(): logger.info('Add method started') db_obj = DatabaseAccess() print("XXX") last_company = db(db.company).select().last() print("YYY") last_data = last_company.update_date print(last_data) rows = db(db.company.update_date == last_data).select() choice_id = request.POST.get('choice_id') print(choice_id) action = request.POST.get('action') current_company = db(db.company.id == choice_id).select().last() user_id = my_auth.get_user()['id'] print(user_id) admin = db(db.site_user.auth_user == user_id).select().first().admin site_user = db_obj.get_user(user_id) auth_user = db_obj.get_auth_user(user_id) print(auth_user) fromaddr = 'strahovka.work2020@gmail.com' toaddr = auth_user.email

toaddr = current_company.email

username = 'strahovka.work2020@gmail.com'
password = ------------
server = smtplib.SMTP('smtp.gmail.com:587')

This code executes till this line "server = smtplib.SMTP('smtp.gmail.com:587')" , then it stops and thats all. But in the server.log there are messages: 2020-09-16 15:51:39 Wed Sep 16 15:51:38 2020 - HARAKIRI ON WORKER 1 (pid: 5, try: 1) 2020-09-16 15:51:39 Wed Sep 16 15:51:38 2020 - HARAKIRI !!! worker 1 status !!! 2020-09-16 15:51:39 Wed Sep 16 15:51:38 2020 - HARAKIRI [core 0] 10.0.0.52 - POST /strahovka/static/add_company since 1600270897 2020-09-16 15:51:39 Wed Sep 16 15:51:38 2020 - HARAKIRI !!! end of worker 1 status !!!

Hi,

I confirm the issue.

With the same parameters on settings.py, it works on Windows with Py 3.7, and the latest Ubuntu on VirtualBox with Py 3.8. But on PythonAnywhere it gets stuck without errors after compiling the registration form. All Py4web becames stuck and is not possible to use any related app. Using 'logging' as the SMTP server allows to submit the registration form. Then, using the token url from logs, is possible to confirm email and then logging inside.

I would open a ticket on pythonanywhere for this

nicozanf commented 3 years ago

I've written in their forum here https://www.pythonanywhere.com/forums/topic/168/#id_post_85479. In fact, Google SMTP services should work for free users, too (see here https://help.pythonanywhere.com/pages/SMTPForFreeUsers/).

I think it's related to this discussion. In fact, it seems a py4web issue (only on PythonAnywhere).

mdipierro commented 3 years ago

I am in contact with Giles at PythonAnywhere and he wants to help make it as simple as possible to use py4web on python anywhere. Tomorrow we should brainstorm what we want to ask.

Hi, this issue can be solved by removing gevent completely (as it's done on the current py4web version), see here.

I think we can close the issue.
