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.

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 am learning to use flask-login for a class. This is an intro class, and we are not using a db for this excercise, rather we are storing credentials (hashed) on a resing file. I am able to authenticate the user credentials, however when the user 'successfully' logs in, instead of redirecting to the protected URL, I am getting redirected to the login page. The code: user model:
...ANSWER
Answered 2022-Feb-23 at 20:10You forgot something when defining the user loader. The function takes a user_id parameter and returns an object of class User, not the class itself. (See documentation)
The following simplified example shows you a possibility of implementation without using a database.
Basically, flask-login stores the attribute id of the user object in the session cookie. Based on this id, the respective user is queried by the LoginManager within the database, which has been replaced here by the class variable / list users.
Database implementations usually have an id column which is defined as unique to the entry. In the example, the unique id of the object is used as a substitute. This means that the mixin's getter will be overwritten. So the example keeps a list of created user objects. Within these users can be found by their id or username.
QUESTION
I have a very simple app that has no user management or any Flask-Login auth needs. It has forms, WTForms. All I want to do is collect some data submitted by the form. I could technically disable CSRF validation but Flask WTForms really urges me not to.
I'd like to disable flask session cookie in the browser because it seems unnecessary and I would need to put a cookie banner for GDPR compliance. So to avoid all that, I thought of disabling flask session cookie as follows:
...ANSWER
Answered 2022-Feb-20 at 19:49I found out from the code base of WTForms: https://github.com/wtforms/flask-wtf/blob/565a63d9b33bf6eb141839f03f0032c03894d866/src/flask_wtf/csrf.py#L56
Basically, session['csrf_token'] is stored in the session and compared against the form.hidden() tag (or form.csrf_token) in the HTML body.
This is not clearly explained in the docs. But the codebase makes it clear. I guess there is no way to do CSRF protection without secure cookies.
The downside of this is that you can't get rid of cookies. I suspect, one could build a server-side session database, but then there are issues with scaling your Flask app horizontally.
QUESTION
I have a problem with transform ldapsearch command to flask_ldap3_login settings.
To check connection to LDAP from Linux server I use this command:
...ANSWER
Answered 2022-Jan-24 at 17:08You tagged active-directory, but I suspect you may not be using AD because you're using uid, which isn't used in AD.
The LDAP_HOST and LDAP_PORT look right.
You have set your LDAP_BASE_DN to the root of your domain, but in your ldapsearch command, you set it to your intranet OU. Why the difference?
The way you set LDAP_USER_DN tells it that all of your user objects are in ou=intranet,dc=mydreamcorporation,dc=com. Is that what you intended?
The way you set LDAP_GROUP_DN tells it that all of the group objects are in ou=people,dc=mydreamcorporation,dc=com. This looks suspicious. I don't think this is what you intended.
You have set LDAP_USER_RDN_ATTR to dn, but if you're using Active Directory, that should be cn according to Microsoft.
You've set LDAP_USER_LOGIN_ATTR to myguid, but this looks suspicious. This should be the attribute that represents the username the user will use to login. In AD, that would be sAMAccountName or userPrincipalName. If you are using some other LDAP server, it will likely be uid.
QUESTION
I have a username and password I built from scratch, this works fine until I thought, people forgetting their password.
I would like to find a way to check when a url has been visited to then change the password for urls like "example.com/fp?id=" that has been sent by email.
I cannot use the flask-security module at this point due to the way I have created the databases and how its integrated into my website.
Yes I have looked, and it seems most ways require using flask-login and flask-security, thanks for any answers in advance :)

QUESTION
So far, User login and registration work okay. Once a user logs in and tries to update username,email,and profile_image (prj/templates/account.html), views/db does not reflect the change.
The user profile pic update does not save the updated picture file under prj/static/product_pics therefore the updated pic does not get reflected in prj/templates/accounts.html.
I am really puzzled over this. What am I doing wrong here? I have been beating my had so hard on this without any luck.

QUESTION
I'm a novice web developer, but experienced python programmer, and Apache dolt. Recently, I've been tinkering with hosting a small website and learning my way through some hosting issues, Flask, html templates, etc.
I've followed several Flask tutorials about controlling access to pages with @login_required decorators on access-controlled endpoints and using session to store a logged in k-v pair. This all works perfectly when running locally on Flask's development server on my local machine. However, when I push this onto my hosting service, I'm getting what I believe is cached behavior to many of the access-controlled endpoints and I'm able to see them after logging out (and checking the session data to ensure the key is removed).
Some specifics...
Using
flaskwithsessionfor the login info, not flask-login.Hosting on a managed VPS that is using Phusion Passenger as a WSGI interface to Apache

ANSWER
Answered 2021-Dec-30 at 20:31Since 5.0, passenger will "helpfully" add cache-control headers to responses it deems 'cachable'.
In order to stop this, your application should add the header Cache-Control: no-store.
