Hi I'm trying to run a Django database management command (specifically,

make_migration

) in a Pants repository. I need to do this outside of the sandbox, since they generate some new files for the codebase. Looking at #12129 and previous discussions, it seems people were working on adding a

run_in_sandbox

flag to

pex_binary

, but it got reverted in #15849. What would be the recommended way to do this now?

A replacement flag was added to the

python_source

target

According to this excellent article:

At this point we need to run

makemigrations

. Unfortunately there isn’t a great path for this on Pants as of writing. What I found worked best was the following.

Copy code

./pants run src:manage -- makemigrations --dry-run --verbosity 3 polls

This command prints the proposed migration files to stdout. You then need to write this output to

src/polls/migrations/0001_initial.py

.

Yup! Everything whose

source

is a Python file is now automatically runnable (albeit in a sandbox). Then you can either set the `run_goal_use_sandbox`flag on the target or the

[python].default_run_goal_use_sandbox

to change the entire repo. Setting it to false runs the source in your repo tree directly. Eventually this will be the default behavior

If I understand correctly, this flag is only available from version 2.13?

Thank you for the replies, temporarily setting

default_run_goal_use_sandbox

to false seems to work, albeit as a workaround. If I can set the flag in

./pants run

, that would be great! E.g.,

./pants run --run_in_sandbox=false

.
