Sometimes getting "migration x was previously applied but has been modified" error even after resetting database

[vbeffa]

Our project has a cargo make target that cycles the database (drops and recreates the database, then reruns migrations). Usually after running this target cargo make run works fine, but sometimes it fails with

Error: migration x was previously applied but has been modified

and it requires cleaning and rebuilding the project to resolve, which takes about 5 minutes so we avoid it when possible.

Any idea why that could be happening? I can't consistently reproduce this behavior.

I'm running into this too sometimes.

Some things I've tried with different levels of success:

• delete the sqlite data file
• cargo clean
• sqlx database drop

[yzernik]

cargo clean seems to fix it.

I faced to same problem with 'postgres' and 'sqlx' and I managed to fix it by removing database and creating i again.

(Warning: you will lost you data)

simply by login as root:

sudo -u postgres psql postgres 

and running:

DROP database db;
CREATE database db;

And I also did add this to my makefile:

pg-reset-db:
	sudo -u postgres psql postgres -c "DROP database db;"
	sudo -u postgres psql postgres -c "CREATE database db;"

so I can do it with one command:

make pg-reset-db

And yes! I know its been a long time🙂. but I faced this error and end up here. so I guess here is a good place to share my exp.
