Flask app NameError: name 'Markup' is not defined

Asked 2022-Apr-09 at 13:07

I have been really stumped on this, been out of this game of web dev/python for a bit. I had a previously working Azure app service running this website, we did a minor HTML spelling change and re deployed. I am assuming some dependency got updated and now its broken. I don't know if this is a packaging version issue or if I have a missing import for my flask app.

I am getting a NameError: name 'Markup' is not defined error when trying to load a static html page. My app starts up just fine but I can't load the actual web pages.

Flask-ReCaptcha is a very old project. The last update of Flask-ReCaptcha is on 2016. You'd better not use it.

Back to the error log itself, Flask-ReCaptcha has code like from jinja2 import Markup. But, since jinja2==3.1.0, Markup's position has changed. Try pip install jinja2==3.0.0`.

You will probably meet other problems as Flask-ReCaptcha is really old.

Python/Docker ImportError: cannot import name 'json' from itsdangerous

Asked 2022-Mar-31 at 12:49

I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.

Here is the full ImportError that I get when I try and run the program:

I was facing the same issue while running docker containers with flask.

I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.

Python MySQL Docker error: Unknown database named main when migrating

Asked 2022-Mar-02 at 19:43

I am trying to migrate my python changes to my docker project, however when I try to run the command python manage.py db migrate I get the error unknown database 'main', however when I look inside of my docker-compose.yml file I see that main is indeed defined inside of the MYSQL_DATABASE variable inside of the container db. I have tried some solutions found on StackOverflow as well as Github like getting the restart: always out of my docker-compose.yml script and making a Windows PowerShell script that will run to restart my docker container as found here: MYSQL Docker container gives "unknown database" error, and trying to change my DATA_SAVE_PATH variable and other such variables in my docker-compose.yml: https://github.com/laradock/laradock/issues/1017 and I have also tried to change the MYSQL_DATABASE variable to a different name but that doesn't work either.

Here is the full error that I am receiving when I run my code:

ANSWER

Answered 2022-Mar-02 at 19:43

I solved this problem by looking in my .dbdata folder and found my service, I then changed the MYSQL_DATABASE variable and the app configuration to the same variable as MYSQL_DATABASE which was vegatest instead of main.

So I ran the same command python manager.py db migrate and I got a successful migration.

SQLAlchemy Joining a Session into an External Transaction Not Working as Expected

Asked 2022-Feb-23 at 17:04

I'm working on rewriting the test suite for a large application using pytest and looking to have isolation between each test function. What I've noticed is, multiple calls to commit inside a SAVEPOINT are causing records to be entered into the DB. I've distilled out as much code as possible for the following example:

init.py

ANSWER

Answered 2022-Feb-23 at 17:04

With the help of SQLAlchemy's Gitter community I was able to solve this. There were two issues that needed solving:

The after_transaction_end event was being registered for each individual test but not removed after the test ended. Because of this multiple events were being invoked between each test.
The _db being yielded from the db fixture was inside the app context, which it shouldn't have been.

Your issue is, I think, with your requirements file. In that you include bson as a dependency, which is also included in the pymongo library. See this question. Removing it seems to solve the issue:

ok, looks like i found my solution here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/12406

quote from Lyle Franklin:

I hit this error when trying to build a cross-platform ARM64 docker image from a AMD64 host. However, running docker run --rm --privileged linuxkit/binfmt:v0.8 or update-binfmts --enable prior to running the build seems to avoid the issue. My understanding Docker will try to use upstream QEMU if it is installed and registered with the kernel, otherwise Docker will fallback to using a built-in forked version of QEMU. The build error above only showed up for me with the forked QEMU.

So I will probably add docker run --rm --privileged linuxkit/binfmt:v0.8 && update-binfmts --enable to my pipeline file if I encounter the error again, for now running it once solved the issue.
