尝试通过Carrierwave和Rails 5远程上传图像时,遇到了编码错误:“Encoding::UndefinedConversionError - "\x89" from ASCII-8BIT to UTF-8”。我已经查看了此答案以及答案建议的activesupport-json_encoder gem,但没有运气。该gem似乎尚不支持rails 5。我的表单是一个正常的多部分rails表单,如下所示:
包含图像的字段称为“附件”。在我的控制器中,我的代码如下所示:
我正在使用 reform gem 处理允许的参数。我已确保允许附件参数。此外,我还添加了 Remotipart gem 以简化通过Rails进行远程文件上传。
任何想法,为什么我可能会出现这个错误?
更新
这是我在日志中看到的:
= bootstrap_form_for @image, url: members_profile_path(current_user), remote: true, html: { multipart: true } do |f|
= f.file_field :attachment
= f.button "Save"
包含图像的字段称为“附件”。在我的控制器中,我的代码如下所示:
def create_profile_image
respond_to do |format|
@image.entity_id = current_user.id
if @image.validate(params[ :image ])
@image.save
format.json { render json: @image, status: :ok }
else
format.json { render json: @image.errors, status: :unprocessable_entity }
end
end
end
