flask-admin | Simple and extensible administrative interface framework | REST library

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.

I have a Flask app deployed on Azure. Without changing any of the dependencies I'm suddenly getting this error, ImportError: cannot import name 'contextfunction' from 'jinja2'. Seems to be related to Flask-admin:

I am trying to start my heroku app with a python flask app, but I am getting the h10 error and the only thing I can see in the log is the Tkinter not found but I am not using Tkinter in this project please help. I've been searching on the web and on other stack overflow questions, but most just say to make sure you don't declare a port or some js server thing. I haven't found anything that helps and when I read the log all I see is the Tkinter but I tried to purge it from my code but it still tries to call it.

I'm creating a registration page which contains 3 input fields: name, email, password. In my User model class, I've created a user_role method:

I have an existing Flask project which uses SQLAlchemy and I wanted to interate an Admin dashboard. Everything worked fine, I managed to enable authentication by using the ModelView Class however if I try to edit or if I try to create a new object of any database model then Flask-Admin throws out the following error:

ValueError: Invalid format string

Here's my Flask-Admin Code:

When I add a new collection through Flask-admin panel I don't get the init method to reduce the image through another function. And when I add a new collection through the Python console everything works. But Flask-admin panel...

Im going through Flask based tutorial "Learn flask framework" by Matt Copperwaite and now am stuck in following error. After adding Flask-Admin I started to build admin dashboard with it. I tried to add Fileadmin module to control static files:

I have a Flask app using Flask-SQLAlchemy with some simple relational data mapping, e.g. between Orders and OrderItems belonging to those orders.

In my Flask-Admin backend I would like to show some of the order attributes in the list of OrderItems — as opposed to having the entire order object. E.g. make the "Order.email" listed (can be read-only) in the OrderItems' rows.

I've looked into the inline_models attribute of the ModelView, but this seems to be more feared towards actually editing the relational object — I just want to display (and sort/search by) some value of the "parent".

Is there a way to achieve this?

I'm fairly new to flask-admin and would like to create a batch action for a view that will primarily do two things:

1. update the Status of the selected record(s) in the table that the action is "Running"
2. kick off a deamon or background process that runs some queries, optimizations, etc.

Edit: For #2) I'll probably want to use Celery. If that's too much weight for standalone question, I'm happy to focus on simply #1), which is: How do I simply update the records I've selected? Seems super trivial but nothing is working.

Edit #2: I found this question which seems to answer the question fairly simply, however I don't undestand what and where the transaction_service.recalculate_transaction is: Flask Admin extend "with select"-dropdown menu with custom button

Here's what I have thus far, but I keep getting a 302 status from the action. So nothing actually happens.

Any help will be greatly appreciated.
