问：

这是代码，它仍然进行交易，一切似乎都很好

// controller
def avatar_create
  Current.user.avatar.attach(params[:avatar])
  if Current.user.avatar.attached?
    redirect_to root_path
  else
    flash[:alert] = "some thing was wrong"
    render :avatar_new, status: :unprocessable_entity
  end
end


//erb
<%= form_with model: Current.user, url: avatar_path, method: :post do |form|%>
  <%= form.file_field :avatar%>
  <%= form.submit "post"%>
<%end%>

和日志

表达式看起来不正确。你真的有模型吗？通常，我希望在 application_controller.rb 中定义类似 where 的东西Current.user.avatar.attach...Currentcurrent_user.avatar.attach...current_user

class Current < ActiveSupport：：CurrentAttributes attribute ：user end // 我正在使用 Rails 7，所以它可能是一个新功能（idk，我是从 youtube 上学到的）

我认为你应该被用来替换.但是，使用那是okie。 习惯于在模型中。让我们在单击“提交表单”时显示日志。current_userCurrent.userCurrent.userCurrent.user

从您共享的日志来看，它似乎在哈希值中。avataruser

  Parameters: {"authenticity_token"=>"[FILTERED]", "user"=>{"avatar"=>#<ActionDispatch::Http::UploadedFile:0x00007f9b30875500 @tempfile=#<Tempfile:/tmp/RackMultipart20230626-4800-tdl8hi.jpeg>, @content_type="image/jpeg", @original_filename="hello.jpeg", @headers="Content-Disposition: form-data; name=\"user[avatar]\"; filename=\"hello.jpeg\"\r\nContent-Type: image/jpeg\r\n">}, "commit"=>"Tạo ảnh đại diện"}

因此，更新到应该可以解决您的问题。params[:avatar]params['user']['avatar']

谢谢，我修复了它，按照你说的做了，或者我只是从表单中删除模型并继续使用 params[：avatar]

如果答案解决了您的问题，您可以将答案标记为已接受，谢谢！
