I have a project I've been working on. Recently swapped out my os drive and did a fresh install of windows. Obviously rebuilding my workflow and I encountered an error.
I try to use db migrate in the context of upgrading my new empty database with the migrations already existing from the my current project. When I try to db upgrade from my venv, nothing happens. Not an error, a message or anything. I check the db and nothing is done. Any ideas what could be causing this? I updated my keys and db logins/uri to reflect the new database still nothing.

I deleted my venv, rebuilt it and reinstalled requirements and everything worked. Hope this helps someone out there.

When I try to install get storage on flutter its not installing. here shows an error. here is the error image -
from the top of the screenshot, I can see that you named your project the same as the get_storage package's name.
and you can't do it, because it conflicts what flutter will consider packages in your project
so you can just change the project name and it will work fine

I am currently trying to add firebase to my Xcode project. I am using Xcode 11. The problem is with the actual cocoapods because now none of my projects using cocapods will build. im currently running cocoapods 1.9.3. All my errors fall under GoogleDataTransport and it says theyre all "lexical or preprocessor issue"s. Any help would be great!
I think this error is related to this issue.
To fix it, you have to modify the build settings.
Select your Pods Project
Go to Build Settings
Set Quoted Include In Framework Header to NO

Right now, my Unity Hub is version 2.1.2. Every time I start the program up, it asks me for an update to version 2.2.2. Every time I install the update, it does install correctly and the application sticks to that new version until I restart my computer. After a restart, it goes back to version 2.1.2, and Unity Hub asks me for that 2.2.2 update AGAIN.
This has been happenning to me for a few months now. Any idea what the issue might be and how to fix it?
Eventually, all I did was just completely reinstall (uninstall, along with Unity) the Unity Hub, and I didn't run into this issue again. Strange...

getting error
redshift failed to load driver class. this error may be caused by all-in-one jar packaging. please try again with the lean package
I had the same issue and the root cause ended up being because the path to the driver file consisted of a folder name that contained a space.
I had the same issue with another program. As workaround try to use com.amazon.redshift.core.jdbc4.PGJDBC4DriverImpl as driver class name. It worked for me using RedshiftJDBC4-no-awssdk-1.2.8.1005.jar
There area number of drivers for Redshift. It seems like you are using an older version. I advise you review the documentation at http://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html
For example, here is the latest driver version.
JDBC 4.2–compatible driver: https://s3.amazonaws.com/redshift-downloads/drivers/RedshiftJDBC42-1.2.8.1005.jar.
Yours seems to be a few point releases older

I successfully integrate the postgres and eclipse but unable to test the database. I need to know where can i get help if any suggestions would be appreciate.By the way i am using java. Thanks in advance.
Selenium is not the right tool here, as it is a tool for automating testing of web front-ends. You cannot directly test your database using this tool.
You can test an application like phppgadmin, but it isn't clear that is what you want.
A better approach is just to write test cases through jUnit and jdbc, in my view. That gives you better control and testing than you can via a web front-end and it is easier to solve the question of whether you want transactions to rollback or not (selenium poses this problem since it is indirect and tests a web app that interacts with the db over a stateless connection).
