I'm following railscasts episode 381 in an attempt to allow multiple image uploads to my app with the carrierwave gem & jQuery File upload.
My app is for a college project & is set up with a hikingtrails model which has many & accepts nested attributes for a pics model.
After I set the multiple option of the file_field to true & hard-coding the input name attribute i.e. <%= form.file_field :image, multiple: true, name: "pic[image]" %>, carrierwave stops working, it doesn't upload a single file as it did before.
Could this have something to do with using nested forms? I've also tried implementing this tutorial into my app without any success.
I've also tried making both forms multi part rather than just the parent form & removing the simple_form gem that I'm using.
I've also tried removing the form partial & putting the nested form in locally but that didn't help. Perhaps it has something to do with how I'm setting the file_field to multiple as this is where the issue began.
Any suggestions or an alternative approach would really be appreciated
