Django app deployment crashes due to cffi and libffi

Trying to deploy a Django app to Railway. After it builds successfully the deployment crashes with this error:

#10 378.9         Running setup.py install for cffi: started
#10 378.9         Running setup.py install for cffi: finished with status 'error'

#10 378.9             Package libffi was not found in the pkg-config search path.
#10 378.9             Perhaps you should add the directory containing

lionelOP•15mo ago

still not working

Brody•15mo ago

send your requirements.txt please

lionelOP•15mo ago

requirements.txt

Brody•15mo ago

does your project use every one of those modules?

lionelOP•15mo ago

probably not

Brody•15mo ago

please remove everything you are not using, let me know when thats done

lionelOP•15mo ago

kk one second sorry I have a question actually. Why is it still installing packages on an old version of requirements? I have changed the requirements.txt file so it shouldn't be doing that right?

Brody•15mo ago

does the repo have the correct requirements.txt in it?

lionelOP•15mo ago

yep anyway. it's somewhat working now. I think there's an issue with my database, as I can't run it locally after some changes will have to fix that first build logs are fine, but deploy logs get stuck on accessing database will get back to you thanks so far

Brody•15mo ago

do you use a railway hosted database?

lionelOP•15mo ago

yeah postgres

Brody•15mo ago

can i see a screenshot of your service variables please

lionelOP•15mo ago

what's that?

Brody•15mo ago

the variables for the railway service

lionelOP•15mo ago

Brody•15mo ago

sorry thats not what i asked for

lionelOP•15mo ago

these ones?

Brody•15mo ago

that is a plugin i asked for the service variables

lionelOP•15mo ago

this one?

Brody•15mo ago

yes you should be using a reference variable, please delete that variable and replace it with a reference variable https://docs.railway.app/develop/variables#reference-variables

lionelOP•15mo ago

which one should i use for postgresql?

Brody•15mo ago

the same one you where already using, just this time its a reference

lionelOP•15mo ago

like this?

lionelOP•15mo ago

Brody•15mo ago

not at all https://docs.railway.app/develop/variables#reference-variables https://docs.railway.app/develop/variables#plugin-variables please read

lionelOP•15mo ago

this way?

Brody•15mo ago

not at all can you please read the docs sections i linked

lionelOP•15mo ago

Brody•15mo ago

can you please read the docs sections i linked

lionelOP•15mo ago

Brody•15mo ago

there we go now please show me your code that connects to the database

lionelOP•15mo ago

settings.py

Brody•15mo ago

you are still using sqlite you will need to add the rest of the pstgres reference variables to your service and then configure your settings.py like this https://github.com/railwayapp-templates/django/blob/main/mysite/settings.py#L81

lionelOP•15mo ago

Brody•15mo ago

looks fine at first glance

lionelOP•15mo ago

so it works, but there's an issue with my code so its not working if that makes sense ahah

Brody•15mo ago

whats your start command

lionelOP•15mo ago

python3 manage.py migrate && python3 manage.py collectstatic --no-input && gunicorn readinghood.wsgi

Brody•15mo ago

also looks good

lionelOP•15mo ago

yeah its my code i was using a mysql database and it was working

Brody•15mo ago

it was using sqlite not mysql

lionelOP•15mo ago

yeah i changed to sqlite to use the mdn tutorial doesnt seem to work using sqlite nor postgres

Brody•15mo ago

whats not working

lionelOP•15mo ago

will retry with mysql and get back to you "django.db.utils.ProgrammingError: relation "book" does not exist LINE 1: SELECT DISTINCT "book"."Category" FROM "book""

Brody•15mo ago

stay with postgres, mysql is costly

lionelOP•15mo ago

deployment_logs_web_...

Brody•15mo ago

just looks like a code issue to me tbh

lionelOP•15mo ago

it does too. but why was it working with mysql? anyway i'll have a look at the code after lunch thanks man!

Brody•15mo ago
