提交带有图像AJAX act_as_votable的表单后收到Action :: Template :: Error

Question

我遇到的问题是，仅包含body_text时将提交表单。 但是，包含图像时，表单不会提交。 我目前正在同时使用remotipart，acts_as_votable和carrierwave。 这个问题似乎与acts_as_votable路线有关。 我在下面显示了。 使用AJAX时，如何获得部分表格以包含图像？

在控制台中显示错误

我使用了错误的表单扩展方法。 现在，它与下面的小改动完美配合。

 <%= f.input :post_photo, as: :file, label: false %>
