I currently have a Blog context with a Post resource and a Comment resource. Comment has a reference to Post. When I’m seeding data in seeds.exs I want to always have the correct post id so that the comment actually belongs to a post. How do I go about doing that? Does Ecto have a function for this?
seeds.exs:
%{
author: "José Valim",
title: "Blog post #1",
text: "This is a very interesting blog post"
}
|> Blog.create_post()
[
%{
text: "Good post",
author: "John Doe"
},
%{
text: "Love it!",
author: "Ada Lovelace"
}
]
|> Enum.each(fn comment ->
Blog.create_comment(comment)
end)
Where Next?

Hey, don’t think it does.
What you are doing is fine.
What you could do is implement some sort of factory pattern to abstract some of that code.
This is referencing testing, but the same pattern could be applied to seeding: Test factories — Ecto v3.14.0
