I'm trying to upload a data_uri image from my webcam by ajax with rails uising this gem
For that I have a custom function on my PicturesController.rb:
def upload_image
data_uri = params[:data_uri]
@picture = Picture.new(picture_params)
@picture.user_id = current_user.id
if data_uri
@picture.photo = data_uri
end
@picture.save
end
and the javascript on my page:
function save_photo() {
Webcam.snap( function(data_uri) {
$.ajax({
type: 'POST',
url: '/pictures/upload',
async: true,
data: { data_uri: data_uri }
})
.done(function () {
console.log(data_uri);
});
// shut down camera, stop capturing
Webcam.reset();
} );
}
I'm also use the gem rack-cors to solve cross domain problems.
My route.rb
resources :pictures do
collection do
post 'upload', :action => :upload_image
end
end
But when I call the ajax function I getting the 400 (Bad Request)
The console show the error:
ActionController::ParameterMissing - param is missing or the value is empty: picture:
Has anyone had this problem before?
Thanks!
