Rails-不允许通过Postman Params发送数组

Question

Im trying to upload images in rails using Carrierwave. but I'm having a problem in permissions

This is my controller:

class PhotoController < ApplicationController
  def upload_multiple
    render json: {
      status: params[:photos].inspect,
    }, status: 200
  end

  def photos_params
    params.require(:photos).permit(:photos => [])
  end
end

Im trying to inspect to debug. The result of inspect is:

"status": "<ActionController::Parameters {\"1\"=>#<ActionDispatch::Http::UploadedFile:0x00007fe8b1ae7d50 @tempfile=#<Tempfile:/var/folders/4w/32p7h9rx2mjf9_m60852pn2m0000gn/T/RackMultipart20190406-1520-1r799qx.jpg>, @original_filename=\"IMG_1303.jpg\", @content_type=\"image/jpeg\", @headers=\"Content-Disposition: form-data; name=\\\"photos[1]\\\"; filename=\\\"IMG_1303.jpg\\\"\\r\\nContent-Type: image/jpeg\\r\\n\">} permitted: false>"

What Im passing in postman is as follows:

What am I doing wrong?

EDIT

Rename the parameter from photos[1] to photos[] . I can't say is this possible in postman, but in terms of html it should be <input type="file" name="photos[]"> (and the form enctype is multipart/form-data ), since it's looks like you're sending a hash, then change params.require(:photos).permit(:photos => []) to params.permit(photos: []) .
