我在rails应用中有一个用于创建产品的表单:
= form_for product, url: url, method: :post, html: { class: 'product-form' }, remote: true do |f|
.row
.col-xs-12.col-sm-6
.form-group.required
= f.label :name
= f.text_field :name, autofocus: true, class: 'form-control'
.col-xs-12.col-sm-6
.form-group.required
= f.label :price
.input-group
.input-group-addon $
= f.number_field :price, class: 'form-control'
.row
.col-xs-12
.form-group
= f.label :description
= f.text_area :description, class: 'form-control'
.row
.col-xs-12
.form-group
= label_tag :images, 'Images'
= f.file_field :images, multiple: true, class: 'form-control'
.row
.col-xs-12.text-right
= f.submit "Cancel", class: 'btn btn-default', data: { dismiss: "modal" }
= f.submit "Save", class: 'btn btn-primary'
它在我的开发环境中运行良好。但是当在heroku(生产)上运行时,单击" Save" (请注意我正在使用Devise并且登录/注册正常),出现此错误:

事情是,当我不选择图像时,它可以正常工作。所以我认为问题可能出在图像上传器上:
模型/ product.rb
class Product
mount_uploaders :images, ProductImageUploader
# more stuff...
end
上传/ product_image_uploader.rb
class ProductImageUploader < CarrierWave::Uploader::Base
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
end
初始化/ carrier_wave.rb
if Rails.env.development? || Rails.env.test?
CarrierWave.configure do |config|
config.storage = :file
config.enable_processing = false if Rails.env.test?
end
else
CarrierWave.configure do |config|
config.fog_provider = 'fog/aws' # required
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: ENV["AWS_KEY_ID"],
aws_secret_access_key: ENV["AWS_KEY_SECRET"],
region: 'us-west-2', # optional, defaults to 'us-east-1'
}
config.fog_directory = ENV['AWS_BUCKET']
config.fog_public = true
config.cache_dir = "#{Rails.root}/tmp/uploads"
end
end
另一件事是我尝试了一个简单的存储::生产中的文件,避免了S3上传的东西,它也失败了。
有什么想法吗?
更新<!/强>
我在表单中添加了 authenticity_token:true ,它没有引发我上面提到的异常。但是,发生了一些奇怪的事情:
ProductsController处理#create as JS
ProductsController处理#create as HTML
更新2!
这是表单标记生成的html:
<form class="product-form" id="new_product" enctype="multipart/form-data" action="/seller/products" accept-charset="UTF-8" data-remote="true" method="post">
<input name="utf8" type="hidden" value="✓">
<input type="hidden" name="authenticity_token" value="SOME STUFF"> </form>
答案 0 :(得分:3)
在表单声明中,在remote: true
之后添加此authenticity_token: true
,如:
form_for product, url: url, method: :post, html: { class: 'product-form' }, remote: true, authenticity_token: true do |f|
