Re: deployment error : django + pgsql

Hi, Arisophy

No it's not the same case as I'm getting error while running "python manage.py makemigrations". But what I have gathered through this time is I need to empty the migration and cache folder as there is no error while creating a new project. I don't know why it's like that.

regards,

Govind

Is that situation similar to yours?

Initially my webapp was using sqlite and I tried migrate my data to postgresdb by following the same procedure as mentioned in the " Dev post " you just shared with me while I was deploying the webapp on nginx server but it failed with error "unknown field (s) (next_post, previous_post)".

After that I configured my project in postgresdb on my system from begining and added all the data in postgresdb so I could easily deploy my webapp, but when I tried to deploy this time I got the error message which I had posted earlier.

In simple words I'm not able to migrate in my already existing webapp(it's on postgresdb on my local machine too).

Regards,

Govind

Are you using postgres on Windows or which database are you using? It's
not really clear from what you're writing, but if you're using sqlite,
then this might help:

https://dev.to/coderasha/how-to-migrate-data-from-sqlite-to-postgresql-in-django-182h

It seems like this has nothing to do with the operating system but is
more of a database migration issue?

It is. You just need to make it clearer what you have done to "prepare
all the data on localhost".

Kind regards,
