ruby - jQuery-File-Upload - Carrierwave - No progress callbacks -


like many others, i've followed rails-cast #381, jquery file upload, , after struggling, have of pieces working. can upload 1 or more files amazon s3 , create corresponding rows in database. i've been stuck couple of days though on getting progress bars work. appear , sit there while file upload , result appears in list when it's finished, bu progress bar stays white. problem seems i'm not getting callbacks. haven't been able work progress:, progressall:, or :done.

i have document model , upload straightforward. i'm using session id keep track of document until second step in process, added in create step. here's relevant code:

documents controller:

... def create     @document = document.new(document_params)     @document.session = request.session_options[:id]  respond_to |format|     if @document.save         format.js         format.html { redirect_to documents_path, notice: 'document created.' }         format.json { render action: 'index', status: :created, location: @document }     else         format.js         format.html { render action: 'new' }         format.json { render json: @document.errors, status: :unprocessable_entity }     end end

documents.js.coffee

$ ->   $('#new_document').fileupload     datatype: "script"     add: (e, data) ->       data.context = $(tmpl("template-upload", data.files[0]))       $('#new_document').append(data.context)       data.submit()     progress: (e, data) ->       if data.context         progress = parseint(data.loaded / data.total * 100, 10)         data.context.find('.bar').css('width', progress + '%')     progressall: (e, data) ->       overallprogress = parseint(data.loaded / data.total * 100, 10);       $('#all_progress .bar').css('width', overallprogress + '%')     done: (e, data) ->       alert("all finished")

index.html.erb

(table of documents here - new uploads insert porperly)  <h2>upload document</h2> <%= form_for document.new |f| %>   <%= f.file_field :original, multiple: true, name: "document[original]" %>   <!-- table listing files available upload/download --> <% end %> <div id="progress">   <div class="bar" style="width: 0%;"></div> </div>  <div id="all_progress">   <div class="upload">     <div class="bar" style="width: 0%;"></div>   </div> </div>  <script id="template-upload" type="text/x-tmpl"> <div class="upload">   {%=o.name%}   <div class="progress">     <div class="bar" style="width: 0%">     </div>   </div> </div> </script>

from javascript, should see alert pop-up @ end of upload well, never happens. show @ beginning of upload if put in add: section. that's working else under .fileupload seems never called.

suggestions on next?

things working (as seems happen when post question). should have noticed when did post, in 2 places thought had 4 spaces, had tab. apparently coffeescript not interpret tabs sets of spaces. didn't throw error, didn't line progress: (e, data) -> , underneath ignored.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
