#create_asset(asset) ⇒ GdsApi::Response

Creates an asset given a hash with one file attribute

Makes a POST request to the asset manager api to create an asset.

The asset must be provided as a Hash with a file attribute that behaves like a File object. The content-type that the asset manager will subsequently serve will be based on the file's extension (derived from #path). If you supply a content-type via, for example ActionDispatch::Http::UploadedFile or another multipart wrapper, it will be ignored. To provide a content-type directly you must be specify it as a content_type attribute of the hash.

Examples:

Upload a file from disk

response = asset_manager.create_asset(file: File.new('image.jpg', 'r'))
response['id']           #=> "http://asset-manager.dev.gov.uk/assets/576bbc52759b74196b000012"
response['content_type'] #=> "image/jpeg"

Upload a file from a Rails param, (typically a multipart wrapper)

params[:file] #=> #<ActionDispatch::Http::UploadedFile:0x007fc60b43c5c8
                  # @content_type="application/foofle",
                  # @original_filename="cma_case_image.jpg",
                  # @tempfile="spec/support/images/cma_case_image.jpg">

# Though we sent a file with a +content_type+ of 'application/foofle',
# this was ignored
response = asset_manager.create_asset(file: params[:file])
response['content_type'] #=> "image/jpeg"

Parameters:

  • asset (Hash) —

    The attributes for the asset to send to the api. Must contain file, which behaves like a File. All other attributes will be ignored.

Returns:

  • (GdsApi::Response) —

    The wrapped http response from the api. Behaves both as a Hash and an OpenStruct, and responds to the following:

    :id           the URL of the asset
:name         the filename of the asset that will be served
:content_type the content_type of the asset
:file_url     the URL from which the asset will be served when it has
            passed a virus scan
:state        One of 'unscanned', 'clean', or 'infected'. Unless the state is
            'clean' the asset at the :file_url will 404

Raises:
