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
Which of the following library versions work well with Airflow 2.2.3 ?
Tried few options but none worked. Fails when initializing db
solution: downgrading no result pip install Flask==1.0.4 pip3 install marshmallow-sqlalchemy==0.17.1
solution: no result pip3 install marshmallow-sqlalchemy==0.17.1 pip3 install SQLAlchemy==1.3.23 pip3 install flask-sqlalchemy
errors: flask-appbuilder 3.4.3 requires marshmallow-sqlalchemy<0.27.0,>=0.22.0, but you'll have marshmallow-sqlalchemy 0.17.1 which is incompatible. apache-airflow 2.2.3 requires flask<2.0,>=1.1.0, but you'll have flask 1.0.4 which is incompatible. apache-airflow 2.2.3 requires werkzeug>=1.0.1,~=1.0, but you'll have werkzeug 0.16.0 which is incompatible.
higher versions when used produuce different error.
...ANSWER
Answered 2022-Jan-11 at 10:14Look at constraint files. You do not have to think about the right versions of dependencies as long as you use golden set of constraints which are generated by Airflow maintainers with every release.
See Airflow documentation about this:
https://airflow.apache.org/docs/apache-airflow/stable/installation/installing-from-pypi.html
You should use constraints when you install airflow - this way the right versions will be automatically found and installed by PIP.
But you can also - if you want manually set those dependencies or even automate version retrieval. For example here you have the set of "golden" constraints for Airflow 2.2.2 and Python 3.7:
https://raw.githubusercontent.com/apache/airflow/constraints-2.2.3/constraints-3.7.txt
QUESTION
I have Airflow deployed in virtual env and in case I try to execute PythonVirtualenvOperator with import of the Airflow module (to get Variables for example) it gives me the AttributeError. Guess I do not fully understand how Airflow executes VirtualenvOperator, and therefore what to do to overcome it, so any suggestions and insights will be highly appreciated
My test DAG code
...ANSWER
Answered 2021-Apr-19 at 16:29It seems that you are confusing the use-cases for PythonVirtualenvOperator and PythonOperator.
If you simply want to run a Python callable in a task (callable_virtualenv() in your case) you can use PythonOperator. In this case, it does not matter if you installed Airflow in a virtual environment, system wide, or using Docker.
What happens in your code is the following: PythonVirtualenvOperator creates another virtual environment (which is completely unrelated to the one in which you run Airflow), installs Airflow into it, and tries to import Variable. But this another Airflow installation is not configured and that is why you get those exceptions. You could set the AIRFLOW_HOME environment variable for this second Airflow installation to the same directory as used by the first Airflow installation, and this should actually work, but it looks like an overkill to me.
So, what you can do is install colorama into the same environment in which you installed Airflow and replace PythonVirtualenvOperator by PythonOperator.
BTW, those print() inside the callable would be redirected into a log file and not printed to terminal, so it probably does not make much sense to use colorama with them.
QUESTION
I'm trying to configure OAuth authentication with GitHub apis, on Superset 1.0.1. Following the docs, I added the following lines in superset_config.py

Answered 2021-Mar-31 at 10:48Maybe I shouldn't have posted the question so early, since it was a very simple error ...
The OAUTH_PROVIDERS variable should be an array!
QUESTION
I'm trying to find some help installing apache-airflow.
I am on MacOS 10.15.7, Python version 3.8.2, and I keep getting an error:
ERROR: Could not build wheels for setproctitle which use PEP 517 and cannot be installed directly
I have tried using earlier versions of pip and python to no avail.
Does anyone know what I can do in this situation? I have looked at all the stack overflow questions that popped up with these search terms but none have presented a solution that worked for me so far.
Any help would be much appreciated.
...ANSWER
Answered 2021-Mar-04 at 00:26I am on MacOS 10.15.7 Python version 3.8.2
I'm guessing you used the Python 3 bundled/pre-installed with macOS Catalina.

...ANSWER
Answered 2020-Oct-31 at 04:48I had the same issue installing apache-airflow 1.10.11 through pipenv. The conflicting dependency appears to be with flask-appbuilder's subdependencies. Pinning marshmallow-sqlalchemy = "==0.16.1" solved the problem for me.

My users should be able to create new rows for my table, but when I use the plus-button in Flask-AppBuilder, the primary key is not shown and the generated SQL INSERT statement is missing the primary key, which obviously fails.
How can I get Flask-AppBuilder to show the primary key for new rows?

QUESTION
I am using gcloud oauth2.0 to access it and store it in new database. But I am getting this weird error:
ERROR:flask_appbuilder.security.sqla.manager:Error adding new user to database. (sqlite3.IntegrityError) UNIQUE constraint failed: ab_user.email
Some more log details:
[SQL: INSERT INTO ab_user (first_name, last_name, username, password, active, email, last_login, login_count, fail_login_count, created_on, changed_on, created_by_fk, changed_by_fk) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)] [parameters: ('Shivam', 'Sahil', 'some secret string', 'another secret string', 1, 'myemail@gmail.com', None, None, None, '2020-06-04 11:45:01.756574', '2020-06-04 11:45:01.756582', None, None)] (Background on this error at: http://sqlalche.me/e/gkpj)
ERROR:flask_appbuilder.security.manager:Error creating a new OAuth user google_<>
As the error says UNIQUE constraint failed, initially I thought my account is pre-registered and since I am trying to re-register it that's why I am getting this error, but here's the deal, when I tried to login using oauth authentication, this is what I am getting:
ERROR:flask_appbuilder.security.sqla.manager:Error adding new user to database. (sqlite3.IntegrityError) UNIQUE constraint failed: ab_user.email [SQL: INSERT INTO ab_user (first_name, last_name, username, password, active, email, last_login, login_count, fail_login_count, created_on, changed_on, created_by_fk, changed_by_fk) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)] [parameters: ('Shivam', 'Sahil', 'google_', '', 1, 'myemail@gmail.com', None, None, None, '2020-06-04 11:57:19.778402', '2020-06-04 11:57:19.778409', None, None)] (Background on this error at: http://sqlalche.me/e/gkpj) ERROR:flask_appbuilder.security.manager:Error creating a new OAuth user google_
I see both of them as the same error, has anyone done any research on this before? Any idea what's going wrong here? I have checked the authentication part well and google authentication page responds correctly on registration or wrong information feed. But even though it gets all the response this error shows up. Any help is highly appreciated!
Flask manager file can be found here: manager.py (In case you're looking for code)

Answered 2020-Jun-05 at 07:22Sorted the issue, Had a very silly problem, was trying to oauth register with an email which I already registered in the database using database authentication.

Install Flask-AppBuilder
You can use Flask-AppBuilder 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.
