S3 Delete

[variousred]

This library used to have an asset delete function for s3 didnt it? How can that be accomplished now?

[variousred]

This is what i'm doing now (coffeescript)

      uploader = EmberUploader.S3Uploader.create
        url: 'http://localhost:3000/api/v1/sign_delete?locationName=' + website.get('name')
        deleteAsset: (asset) ->
          self = this
          @signDelete(asset).then (json) ->
            url = asset.get('url')
            type = 'DELETE'
            self.authorizationAjax url, 'DELETE', json
        signDelete: (file) ->
          settings = 
            url: @get('url')
            type: 'GET'
            contentType: 'json'
            data: name: file.get('url').split('/').pop()
          @_ajax settings
        authorizationAjax: (url, method, signatureJson) ->
          self = this
          settings = 
            signature: signatureJson['signature']
            url: url
            type: method or 'POST'
            contentType: false
            processData: false
            headers:
              'Authorization': 'AWS4-HMAC-SHA256 Credential=' + signatureJson['aws_access_key_id'] + '/' + signatureJson['simple_date'] + '/' + signatureJson['region'] + '/s3/aws4_request, SignedHeaders=host;x-amz-date, Signature=' + signatureJson['signature']
              'x-amz-date': signatureJson['iso8601_date']
              'x-amz-content-sha256': 'e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855'
          @_ajax settings
      uploader.deleteAsset(asset).then ((response) ->
        website.get('assets').removeObject(asset)
        asset.deleteRecord()
        asset.save()

I don’t think I’ve ever had a delete function for it.

Any update for this issue ?

[digitaltoad]

I haven't had time to look into this.

[ValentinTrinque]

Do you have any idea how you want to implement it ? I would be interested in participating.

[peavers]

@ValentinTrinque this could be as simple as something like this

/**
* Deletes an S3 Asset
* @param asset
*/
deleteAsset(asset) {
    // You'll need to sign this somewhere, or have open permissions on your bucket - not recommended
    const url = `https://${asset.get('bucket')}.s3.amazonaws.com/${asset.get('key')}`;

    return this.get('ajax').delete(url).then(() => {
    asset.destroyRecord();
  });
},

Assumes your asset is the response from uploading, something like

import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
  location: DS.attr('string'),
  bucket: DS.attr('string'),
  key: DS.attr('string'),
  eTag: DS.attr('string'),
});

@peavers I am not working on the project with requiring this. However, thank you for the tip.
