Hi in mac os i have no problem. in windows when My colleague clone the project and fresh install (after create db and migrate all migrations) , it gets this error in my phoenix project! (without any new changes) or changing anu resource code!

Confusion with before_transaction timing and doing changes before manage_relationship
Hello, I am basically trying to use the data from a third party API call to create a related resource in manage_relationship.
Reading the doc I decided that it would make sense to call the API in a
before_transaction hook. The docs is stating the following execution order for a create action:
```...Solution:
Changes/validations run and then when you call the action before_transaction hooks are the first hooks to run
Conversion of strings with just whitespace when storing in postgres
We are moving data from old systems to a new system and noted that one entry had a tax number of
" ".
Now, that is not a valid tax number, but we realized that the corresponding DB row has a value of null instead.
Is this the default behaviour for strings that contain only whitespace?
Is there an option to disable this behaviour and what are the caveats if we do?...manage_relationship not creating many-to-many join records

How to load a limited amount of related records (and maybe store as virtual attr?)
Still pretty new to Ash and ran into some issues yesterday getting some data into my liveview. What I want to do is load a relationship when I fetch a collection of records, but only take the most recently inserted record. That would then either be accessed as something like a 'virtual field' on the main record or through the relationship (not sure what's best). How would I accomplish this?
E.g. a
Document :has_many :stats, and I want to load the accompanying, most recent Stat only (for each Document) whenever I fetch a Document collection.
