[英]How to delete attachment using refile ActiveRecord::RecordNotFound
I'm trying to delete / destroy an attachment I have uploaded using the refile gem, and I'm currently getting the following error, ActiveRecord::RecordNotFound in ImagesController#destroy
我正在尝试删除/销毁使用重文件gem上传的附件,并且当前出现以下错误,
ActiveRecord::RecordNotFound in ImagesController#destroy
Couldn't find Image with 'id'=
images_controller.rb images_controller.rb
def destroy
# binding.pry
@image = Image.find(params[:id])
@image.destroy
flash[:notice] = 'deleted'
render 'new'
end
private
def image_params
params.require(:image).permit(:tshirt_image, :remove_tshirt_image)
end
And the form / view in which I'm trying to delete the attachment looks like, 我试图删除附件的表单/视图如下所示:
show.html.erb show.html.erb
<h1>show.html.erb</h1>
<% debug(@image) %>
<%= image_tag attachment_url(@image, :tshirt_image, :fill, 300, 300, format: "jpg") %>
<%= form_for @image do |form| %>
<%= form.label :tshirt_image %>
<% form.attachment_field :tshirt_image %>
<%= form.check_box :remove_tshirt_image %>
<%= form.label :remove_tshirt_image %>
<%= button_to "delete", @image, method: :delete %>
<% end %>
<p>test</p>
If I'm reading your code correctly, all of your form's params will be nested under the :image
key ( params[:image][:remove_tshirt_image]
, etc). 如果我正确地阅读了您的代码,则表单的所有参数都将嵌套在
:image
键下( params[:image][:remove_tshirt_image]
等)。
Try: 尝试:
@image = Image.find(params[:image][:id])
