Nested items

[sultanmyrza]

Hello,
I'm trying to use your library for my case. I read the documents but still not sure will this package work for me?

My case

Here is my case. I'm basically trying to build simple version of iCloud.
I need to do CRUD operations with items object (by item I refer to file or directory in my case).

Here are examples responses
**GET request root directory ** https://api.myserver.com/api/v1/files/users/userId?limit=30&offset=0&direction=asc

{
   "data": [
       {
           "id": "1dd379dd-e9f1-49d5-8d57-01c2f231fd5d",
           "type": "FILE",
           "filename": "3.PNG",
           "preview": "{{ preview_url }}",
           "uploadUrl": "{{ upload_url }}"
       },
       {
           "id": "613d1e22-f82a-49b7-86c1-05e1ff4fc44a",
           "type": "FILE",
           "filename": "31.PNG",
           "preview": "{{ preview_url }}",
           "uploadUrl": "{{ upload_url }}"
       },
       {
           "id": "7e4edba5-9644-4e7e-b991-3b5d4ac53b8f",  <--- subDirectory
           "type": "DIRECTORY",
           "filename": "my directory"
       }
   ]
}

GET request subdirectory https://api.myserver.com/api/v1/dir/{{subDirerectoryId}}/users/{{userId}}?limit=30&offset=0&direction=asc

in this case subDirectoryId = 7e4edba5-9644-4e7e-b991-3b5d4ac53b8f

{
    "data": [
        {
            "id": "0966c025-2894-4d33-849f-e5aae9abedf1",
            "type": "FILE",
            "filename": "MY MOVIE.MP4",
            "preview": "{{ preview_url }}",
            "uploadUrl": "{{ upload_url }}"
        },
        {
            "id": "31ebc4c8-105b-422e-a106-0b14fcb4db67",
            "type": "FILE",
            "filename": "MY CODE.ZIP",
            "preview": "{{ preview_url }}",
            "uploadUrl": "{{ upload_url }}"
        },
        {
            "id": "117f89da-1929-48ea-985b-d8384724b9b7",
            "type": "DIRECTORY",
            "filename": "another directory"
        },
        {
            "id": "c8c191b9-4c78-407d-b826-f07550357415",
            "type": "DIRECTORY",
            "filename": "my vocation"
        }
    ]
}

My Questions

I read about relationships

Remove a relationship
Given a Post with many Comments we want to remove:

final postWithNoComments = post.copyWith(comments: HasMany.remove()).was(post);
Works with both HasMany and BelongsTo.

Removing a relationship does not delete its linked resources (the actual comments in this case).

Question 1.

If removing a relationship does not delete its linked resources what can I do? For now I see one solution.

Which is to loop through post.comments and delete each comment. But I'm not sure what will happen inside flutter_data
will it updated.

Also wondering what will do flutter_data when I will move multiplie files to another sub directory?

My final thoughs

P.S: I think this package is good enough 👍.
If this packages works for my case I would be happy to contribute or just buy a coffee 😅.

It's definitely possible. Deleting can be done as you describe. Moving is simply using relationships to link to another resource. Tree-like structures are also possible. There are tests showing all of these capabilities.
