Combining modules fails

Question

I want to connect all the models but I always get those cycle-errors.

My whole model looks like this:

type alias Model =
    { users : List User
    , blogs : List Blog
    , posts : List Post
    , comments : List Comment
    , labels : List Label
    }

Sadly there appears the error message:

Your module imports form a cycle:
  
  ┌─────┐
  │    Features.User
  │     ↓
  │    Features.Blog
  │     ↓
  │    Features.Label
  │     ↓
  │    Features.Post
  │     ↓
  │    Features.Comment
  └─────┘

This is the user file:

module Features.User exposing (..)

import Features.Blog as Blog
import Features.Comment as Comment
import Features.Post as Post


type alias Id =
    String


type alias User =
    { id : String
    , name : String
    , email : String
    , password : String
    , blogs : List Blog.Id
    , posts : List Post.Id
    , comments : List Comment.Id
    }

I would love to get some input how to restructure the code so that it works just fine. Thanks.
