尝试使用CarrierWave删除上传的图像
在控制器中获取这些参数
<%= f.fields_for :images do |ff| %>
<div class="form-group">
<label>
<%= ff.check_box :remove_image %>
<%= image_tag ff.object.image %>
</label>
</div>
<% end %>
在控制器中获取这些参数
"images_attributes"=>{"0"=>{"remove_image"=>"0", "id"=>"13"}, "1"=>{"remove_image"=>"1", "id"=>"14"}, "2"=>{"remove_image"=>"0", "id"=>"15"}, "3"=>{"remove_image"=>"0", "id"=>"16"}, "4"=>{"remove_image"=>"0", "id"=>"17"}, "5"=>{"remove_image"=>"0", "id"=>"18"}}}
但是当使用这些参数更新对象时,没有任何变化,我错过了什么?
更新
def update
@country = Country.find(params[:id])
if @country.update(country_params)
flash[:notice] = 'Country is successfully updated.'
redirect_to edit_admin_country_path
else
flash[:error] = @country.errors.full_messages[0]
render 'edit'
end
end
def country_params
permitted = [{images_attributes: ["image", "@original_filename", "@content_type", "@headers", "_destroy", "id", "remove_image"]}]
params.require(:country).permit(*permitted)
end
class Country < ActiveRecord::Base
has_many :images
....
end
class Image < ActiveRecord::Base
mount_uploader :image, ImageUploader
belongs_to :country
end
