@billy1624 I definitely need some assistance here 😄 I'm getting this error after making some of the changes and to be honest I don't understand why this is suggested. Should we have done certain things differently to avoid this error? 🙏

Hey @nahuakang, sorry for the confusion. Here is what I want to do. Please check master...demo-migration-connection and see if that make any sense :)

I think is better to use &database_schema

[billy1624]

Hey @nahuakang, regarding your question on how to add schema name prefix to TableRef. I think we need to create a trait in SeaQuery where we can get and alter the TableRef of any type implemented the trait.

pub trait SchemaDefinitionStatement {
    fn get_table_name(&self) -> Option<&TableRef>;

    fn set_table_name(&self) -> &mut Self;

    fn prefix_table_name_with_schema<A>(&mut self, schema: A) -> &mut Self
    where
        A: IntoIden + 'static;
}

Following types should implement the new SchemaDefinitionStatement trait:

• TableCreateStatement
• TableAlterStatement
• TableDropStatement
• TableRenameStatement
• TableTruncateStatement
• IndexCreateStatement
• IndexDropStatement
• ForeignKeyCreateStatement
• ForeignKeyDropStatement
• TypeCreateStatement
• TypeAlterStatement
• TypeDropStatement

Also, we need a helper method to apply the schema name on the TableRef:

impl TableRef {
    pub fn schema<A>(self, schema: A) -> Self
    where
        A: IntoIden + 'static,
    {
        match self {
            ...
        }
    }
}

Hey @nahuakang, I find a way to achieve the same thing with less code. Please check #1056

[nahuakang]

Hey @billy1624 So #1056 Can close this one? :) Thanks!

[billy1624]

Hey @nahuakang, I will close this in favour of #1056. Thanks for the contributions as always! :)

[nahuakang]

@billy1624 Thank you! I'll pick up where I left off on sea-query later this month :) Have too many things to handle right now outside open source 😅

[billy1624]

Thanks!! @nahuakang Take your time :D
