No callback to server with dropzone.js

[padhug]

Hi, It's working fine if I sent file with input file selector. When I start using dropzone.js I'm getting 201 from amazon s3, but couldn't figure why it's not posting back to server, i tried manually adding callback_url in dropzone configuration as well.

This is my code now.

<%= s3_uploader_form callback_url: projects_path, callback_param: "project[import_file]", max_file_size: 5.megabytes, id: "s3-uploader", data: {:key => :val} do %>

<%= hidden_field_tag "Content-Type", ""%>

<%= file_field_tag :file, multiple: true %>

<% end %>

I managed to post server from dropzone.js events manually.

@padhug Can you explain your way? I have been problem with dropzone in this gem. Thank you very much.

Hi, We can use dropzone.js events to post server, this should work from your application.js

Dropzone.autoDiscover = false; // or disable for specific dropzone: //Dropzone.options.myDropzone = false;

$(function() { // Now that the DOM is fully loaded, create the dropzone, and setup the // event listeners var myDropzone = new Dropzone("#s3-uploader");

//This success event runs after successful uploads to s3 myDropzone.on("success", function(file, response) { /* Maybe display some more file information on your page */

console.log("added");
var xmlDoc = $.parseXML( response ); var $xml = $( xmlDoc ); var $title = $xml.find( "Location" );

      $.ajax({
       url: '/projects.js', 

       type: "POST",  // type should be POST
       data: { project: { import_file: $title.text(), name: file.name} }, // send the project object

       success: function(response){

       },
       error: function(response) {

       }
    });   

}); })

There is plenty of event functions available from dropzone.js which we can use, pls check their docs.

Thank you for your reply soon :heart_eyes: In my case, when i used dropzone, i lost unique_id of files. I need unique_id to make s3_directory.

Maybe i can't use dropzone in my project. Sorry for inconvenience. Have a nice day!

When I tried to upload more than 5 images and maxFiles is set to 8, I can't get any success callback, but it works fine with less than 5 images, This issue aeries with Amazon S3 bucket.
