I have a model Tcave where an attribute is described like this:

idAuthor: {
      columnName: 'id_author',
      type: 'number',
    },

When I try to run create on this I get the following error: Unexpected error from database adapter: column "idAuthor" of relation "t_cave" does not exist

This is normal because the table t_cave do not has a column idAuthor but it has the column id_author

If I change the attribute to this, it is working fine:

id_author: {
      columnName: 'id_author',
      type: 'number',
    },

Is this related to this question ? https://stackoverflow.com/questions/37516556/sails-js-one-to-many-relationship-with-custom-column-names

@bsoufflet Thanks for posting! We'll take a look as soon as possible.

In the mean time, there are a few ways you can help speed things along:

• look for a workaround. (Even if it's just temporary, sharing your solution can save someone else a lot of time and effort.)
• tell us why this issue is important to you and your team. What are you trying to accomplish? (Submissions with a little bit of human context tend to be easier to understand and faster to resolve.)
• make sure you've provided clear instructions on how to reproduce the bug from a clean install.
• double-check that you've provided all of the requested version and dependency information. (Some of this info might seem irrelevant at first, like which database adapter you're using, but we ask that you include it anyway. Oftentimes an issue is caused by a confluence of unexpected factors, and it can save everybody a ton of time to know all the details up front.)
• read the code of conduct.
• if appropriate, ask your business to sponsor your issue. (Open source is our passion, and our core maintainers volunteer many of their nights and weekends working on Sails. But you only get so many nights and weekends in life, and stuff gets done a lot faster when you can work on it during normal daylight hours.)
• let us know if you are using a 3rd party plugin; whether that's a database adapter, a non-standard view engine, or any other dependency maintained by someone other than our core team. (Besides the name of the 3rd party package, it helps to include the exact version you're using. If you're unsure, check out this list of all the core packages we maintain.)

Take a look at my comment over here: https://github.com/balderdashy/sails/issues/7105#issuecomment-784240108

This will unblock you and it's pretty straightforward.

Hey @bsoufflet, I was taking a look at this, and I wasn't able to reproduce the issue you're running into. If you create a repo with a fresh Sails app that reproduces this, I'd be happy to look at it. Thanks!

I believe I found our issue here. It is because in the model there is a numeric attribute named length

The function that converts the model attributes to the database column name: transformer.serializeValues() use _.each() However _.each() expects an array-like collection An object with a length property will be interpreted as an array instead of an object like expected here More detail here: https://github.com/lodash/lodash/issues/277

Using _.forOwn() like recommended solves the issue
