Question

我想使用RoR在图像标签中设置一个图像。该图像路径是从DB中获取的，它必须设置内部图像标记。我已经完成了一些编码但无法显示该图像。它还显示以下错误。

错误：

SyntaxError in Homes#home

Showing C:/Site/swargadwara_puri/app/views/homes/home.html.erb where line #209 raised:

C:/Site/swargadwara_puri/app/views/homes/home.html.erb:209: syntax error, unexpected $undefined

209:                 <div class="text-center bpaddingdiv1"><% image_tag("<%= @hcsy.D_Photo %>",:height => "140",:border => '0',:class =>'borderblackdiv' ) %></div>
210:                 <div class="fontweightbolddiv fontssizediv3 text-center bpaddingdiv1">Deceased Photo</div>
211:             </div>
212:             <div class="col-md-4">

请检查我的下一行。

<div class="text-center bpaddingdiv1"><% image_tag("<%= @hcsy.D_Photo %>",:height => "140",:border => '0',:class =>'borderblackdiv' ) %></div>

请帮我解决此错误并成功显示此图片。

试试这个，

<div class="text-center bpaddingdiv1"><%= image_tag("#{@hcsy.D_Photo}",:height => "140",:border => '0',:class =>'borderblackdiv' ) %></div>

更改为：<% image_tag...至<%= image_tag和"<%= @hcsy.D_Photo %>"至"#{@hcsy.D_Photo}"

<强>被修改

将"<%= @hcsy.D_Photo %>"更改为"/#{@hcsy.D_Photo}"

使用rails 3在image-tag中设置图像。
