I noticed that .import has been deprecated in beta6, is there an upgrade path or best practices on how to migrate existing code?

The upgrade guide only mentions that the function has been deprecated, but offers no other directions. 😅

Hi @MichielDeMey, thanks for the comment, we should improve that part of the docs. Can you tell me more about your situation? Can you give an example of code snippet that you have using import?

Does your case stem from this issue in the CLI or is it something else?

[MichielDeMey]

Yep, looks like the code was originally generated by the CLI.
We can follow up on that issue regarding the deprecated import method. 👍

For those coming here and tryign that old issue with CLI which is now gone, here's how you can migrate.

From:

sequelize.import(path.join(__dirname, '', filename));

To:

require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);

I switched over to using the require line and am now getting this error (using Node 14 and Sequelize 6):

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\.....\models\Permissions.js
require() of ES modules is not supported.
require() of C:\.....\models\Permissions.js from C:\.....\models\index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename Permissions.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\.....\package.json.

I don't want to rename all my models to .cjs and I don't want to remove "type":"module", so I'm wondering what my options are here. I can't be the only one trying to do this on Node 14 and Sequelize 6.

@mdodge-ecgrow did you find a solution? I have the same problem

[ephys]

you need to use import instead of require
