It’s because You are not familiar (yet) with the syntax.
It should be attrs \\ %{} (with 2 backslahes)
It’s just a way to define default value… like attrs = default would be in js.
The cryptic %{} defines a map, and %User{} is a struct. You might see there is a rich set of datatypes.
- list, THIS IS NOT AN ARRAY!
- {} tuple
- %{} map
- %User{} struct
These datatypes are common in FP, and You need to learn properly how to use them.
Instead of chaining, like OOP would do, You find pipes (|>) in Elixir, where You provides data to a functional pipeline. Instead of this->db->insert_id() You will find id |> insert_id(), with the Repo pattern.
Please use ``` to wrap your code, it will make it more readable, as in markdown.
