Rails 4: Validate file, then import if conditions met -

-

i importing file using smartercsv , have 1 function validates aspects of file, , redirects you, displaying results.

i display include button says "import", allows import same file long satisfied displayed.

how can pass file second function after redirect without having select file again?

# validate file , check display def check_file     @success, @error = timecard.check_timecard(params[:file])     redirect_to timecards_path, notice: [@success, @error] end  #import database if display satisfactory def bulk_upload     x = timecard.import(params[:file])     redirect_to timecards_path, notice: "times imported successfully." end  #view showing display <% if flash[:notice].is_a? string %>     <%= flash[:notice] %> <% elsif flash[:notice].is_a? array %>     <div class="container">         <div class="col-xs-10 col-xs-offset-1">             <table class="table table-hover table-striped table-bordered">                 <thead>                     <tr>                         <th>name</th>                         <th>regular</th>                         <th>overtime</th>                         <th>sick</th>                         <th>vacation</th>                         <th>holiday</th>                     </tr>                 </thead>                 <tbody>                     <% notice[0].each |success| %>                     <tr>                         <td style="color: green"><%= success[0] %></td>                         <% success[1].each |type| %>                         <td><%= type %></td>                         <% end %>                     </tr>                     <% end %>                     <% notice[1].each |failure| %>                     <tr>                         <td style="color: red"><%= failure[0] %></td>                         <td><%= success[1] %></td>                     </tr>                     <% end %>                 </tbody>             </table>         </div>          <div class="container-fluid">             <div class="col-xs-12 col-md-6 col-md-offset-3 text-xs-center">                 <div class="card card-nav-tabs">                     <div class="header header-info">                         import timecard , send email                     </div>                     <div class="content">                        <!-- import goes here -->                      </div>                 </div>             </div>         </div>     </div> <% end %>

there nice way this. should move file location within application , then, store path of file in database against record trying upload file to. consider following example. assuming uploading file timecard record , instance exist @time_card

name = params[:upload][:file].original_filename directory = "public/images/upload" path = file.join(directory, name) file.open(path, "wb") { |f| f.write(params[:upload][:file].read) }  @time_card.csv_path = path

then, redirect user validation error page. then, after use submits page can import csv using file in @time_card.csv_path

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
