QUESTION
I am using Airflow 2.0 and have installed the slack module through requirements.txt in MWAA. I have installed all the below packages, but still, it says package not found
...ANSWER
Answered 2022-Apr-10 at 04:33By default, MWAA is constrained to using version 3.0.0 for the package apache-airflow-providers-slack. If you specify version 4.2.3 in requirements.txt, it will not be installed (error logs should be available in CloudWatch). You'll have to downgrade to version 3.0.0.
apache-airflow-providers-slack (constraints.txt)
OR
Add constraints file to the top of requirements.txt to use version 4.2.3 of apache-airflow-providers-slack.
Add the constraints file for your Apache Airflow v2 environment to the top of your requirements.txt file.
QUESTION
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.
Full Traceback
...ANSWER
Answered 2022-Apr-09 at 13:07Flask-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.
QUESTION
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:
...ANSWER
Answered 2022-Mar-27 at 07:41contextfunction was replaced by pass_context in Jinja2 3.0.0 so it's definitely a dependency problem. Can you downgrade the Jinja version or should you be running python 2 for this app?
QUESTION
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.

QUESTION
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:
...ANSWER
Answered 2022-Feb-08 at 09:50You have your user_roles method defined as a class method when it can and should probably be a static method. Also you are calling user_roles with the email string but the try to access self.email in the method. Just change that and you are good to go.
QUESTION
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:
...ANSWER
Answered 2022-Jan-29 at 04:35bro I had a similar issue to yours, where the exception stemmed from the "date_posted" field in my "Threads" table as by default flask admin reads all data object as a String object so you have to override it as follows in your adminmodelview for example: form_overrides=dict(date_posted=DateTimeField)

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...

...ANSWER
Answered 2021-Oct-30 at 19:51I ended up rewriting the view model this way and it worked, but I had to write a separate html for it and it looks really weird, but it will do. If you have any better ideas, suggest them.
QUESTION
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:
...ANSWER
Answered 2021-Dec-15 at 12:19Solved - manually changed validators.required() call to validators.DataRequired() in flask-admin -> fileadmin init.py . They distinguished them in v1.0.2 (https://wtforms.readthedocs.io/en/stable/changes/#version-1-0-2).
QUESTION
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?
...ANSWER
Answered 2021-Nov-23 at 16:55You can easily include fields via a foreign key relationship by including them in column_list value - documentation. Consider the two simplified models, note the company back reference in the Address model:
QUESTION
I'm fairly new to flask-admin and would like to create a batch action for a view that will primarily do two things:
- update the Status of the selected record(s) in the table that the action is "Running"
- 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.
__init__.py
...ANSWER
Answered 2021-Oct-14 at 18:30OK.
- So ultimately #1 was easy to answer, as I mention in my comments above. I was importing the db from the
__init__.pyfile, where I should have been importing from thedb.pyfile. I'm not sure I need to initialize the DB in the__init__.pyfile, but that's a different question. Here is the fix:

Install flask-admin
You can use flask-admin like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
