Update failed error in - mongify process command

[jyotman]

I'm getting an error using the mongify process command.
All the data is copied to MongoDB from PostgreSQL but the respective foreign key ids are not updated.

This is the error I get -

This is my translation file -

This is the database.config file -

sql_connection do
  adapter     "postgresql"
  host        "localhost"
  username    "******"
  password    "******"
  database    "*******"
  batch_size  10000
end

mongodb_connection do
  host        "localhost"
  database    "**********"
end

I got the same problem. I try to rollback Mongo database from version 3.4 to 3.2 and the error is gone.

[artjomg]

any fixes planned for this?

[anlek]

Hey @artjomg, I'm unable to dedicate time to fix this at the moment, but will gladly review pull requests.

[optimus93]

Done ... downgrading to 3.2 works.. no more errors...evrything running smooth ..thnks

[optimus93]

@anlek - hey brother... can we merge columns of two different tables in mongify ?

[anlek]

@optimus93 Yes, you can, by embedding one into the other, and using the before_save method and pushing the values to parent_row. Read the docs to learn more.

Dear @anlek ,
Nowadays MongoDB lowest version is 4.4 (and it's not possible to use MongoDB version 3.2 anymore due to it's end of life being on 2018). Given that the problem mentioned in this issue came up again and once the downgrade is not a solution anymore. Is it possible to have another fix/workaround for that issue?
Thanks in advance.

[anlek]

Unfortunately, I don't have a solution at this time. If I had more time, I might be able to upgrade the dependencies. However, life is a bit busier these days then it used to be.
