Question

我正在使用Paperclip将图像添加到我的模型AgentActivity中，它按原样显示在表单上，但是当我更新表单时，它似乎没有保存。我的控制器更新方法正在保存除图像以外的所有参数，因此我认为它设置正确，但是我看不到哪里出错了？我还根据提供的文档设置了model.rb文件...

表格

> Z=5
> round(367.8/Z)*Z
[1] 370
> round(367.2/Z)*Z
[1] 365

控制器更新方法

// current value of the location href attribute
let currentURL = $(location).attr("href");

// value we intend to change it to
let redirectURL = "https://yellow.brick.road/"

if (currentURL !== redirectURL) {
    $(location).attr("href", redirectURL);
} else {
    location.reload();
}

Params

 <%= image_tag @submission.agent_activities.last.image.url(:large) %>

 <%= form_for @submission, html: { multipart: true } do |f| %>

   <%= f.fields_for :agent_activity do |a|%>


      <td> <div class="field">

        <%= select_tag(:Status, options_for_select([['In Progress', 1], ['Not Interested', 2],['Viewing Arranged', 3]])) %>

      </div>
    </td>

    <td> <div class="field">
  <%= text_field_tag :Notes %>
 </div>
  </td>

   <%= f.file_field :image %>
  <td>
    <div class="actions">
      <%= f.submit %>
  </div>
</td>
<% end %>
  <% end %>

agent_activity.rb

   def update


respond_to do |format|

    if user_signed_in?
    @submission.update(submission_params)
    format.html { redirect_to @submission, notice: 'Submission was successfully updated.' }
    format.json { render :show, status: :ok, location: @submission }
  else

    if agent_signed_in?
      #AgentActivity.create(agent_activity_params)
    AgentActivity.create(agent_id: current_agent.id, submission_id: @submission.id, Notes: agent_activity_params[:Notes], Status: agent_activity_params[:Status] , image: agent_activity_params[:image])
    format.html { redirect_to @submission, notice: 'Activity was successfully updated.' }
    format.json { render :show, status: :ok, location: @submission }

  else
    format.html { render :edit }
    format.json { render json: @submission.errors, status: :unprocessable_entity }
  end
end
end

结束

Schema.rb

    def agent_activity_params
  params.permit(:id, @submission.id, :Status, :Notes, :image)
    end

避免回形针。使用Rails自己的功能ActiveStorage，因为回形针已弃用。您可以在回形针gem文档中获取详细信息。

回形针未在模型中保存图像
