[BUG] Media (image) set to null after import, even if field is not in imported file

[NicolasBrondin]

Describe the bug
Everytime we update content by importing data using CSV or JSON, any media field on the root of the schema is set to null, even if the said files doesn't contain the field column

The problem happens even if we let the column with exactly what was exported in the first place (full object or id)

To Reproduce

1. Create schema with media field in it
2. Add some content with media such as an image
3. Export data
4. Import exported data after removing media column

Expected behavior
Media data is unchanged

Also its important noticed, when you have more then one level in component. Import are missing populate for media types, I suppose is same problem of new API required specify populate level

[Baboo7]

I'm actively working on importing media

[Baboo7]

I published version 1.6.4 that supports media upload. Check the Config section of the doc for proper setup.
I did a few tests and it seems to work properly but I'm waiting for your feedback

[Baboo7]

Version 1.6.5 available. Check out the Importing Data section of the doc.

[middlebaws]

So, Service now should be setup in ./src/extensions?
Like this example in doc: https://docs.strapi.io/developer-docs/latest/development/plugins-extension.html#extending-a-plugin-s-content-types

Or need to be setup inside of serve.js from api?
Like this doc: https://docs.strapi.io/developer-docs/latest/development/backend-customization/services.html#adding-a-new-service

In my case I have this sceneario (really similar to what Nicolas describe),

  {
    id: 8,
    title: null,
    Banner: [ [Object] ],
  },

In my case, this Object inside Banner lose everything during import/export process. 😞

[Baboo7]

There is no service to setup (did I misunderstand something?). Version 1.6.5 should fix the issue about importing/exporting media.

About the objects exported as [ [Object] ], I'll dig into that. How deeply nested is the data having the issue?

[middlebaws]

About Setup, sorry maybe I misunderstand documantation. I understand need to configure service now to have better compatibility when export. But thanks to clear, now its fine.

About how deep I'm using, let me try example here.
I just erase URL for s3 bucket (security), but you can sure its working.

Version 1.7.0 is out and export has been rewritten. It should work as expected now

[middlebaws]

Working pretty good now!
Just get problem when you import for different language, seems need to apply same concept to deeply components.

I mean, when import in:

• English (default) > 100% working
• Spanish (second language) > 50% Simple components work, but if have something more deep like:

  {
    id: 8,
    title: null,
    Banner: [ [Object] ],
  },

Not work =/

Forget to mention, I tested in 1.7.1 version.

[Baboo7]

Version 1.10.0 is out. Deepness can now be set in the export modal
