一个接一个的问题哈哈，但我离完成我的项目太近了！！
所以我完成了我的 Ruby on Rails 程序并开始工作。现在我正在尝试将其集成到 HTML 模板中。
我终于得到了正确加载的图形和模板，但仅限于 index.html.erb 页面，因为那是起始页面。现在我的问题是我的控制器文件中定义为“结果”的页面无法正确显示。看起来这可能是一个简单的修复，但不确定如何。看起来内联 css 样式根据result的格式正常工作，但是我的 style.css 中的图像和样式现在没有为模板加载（除了索引）。
我把 images 目录作为 public 的子目录。我也有公开的 style.css。
我在视图中有一个名为“ customerdisplay.html.erb ”的页面，其中包含我的模板的 HTML 编码。该文件中的 div 标签之一是我的外部样式表中的自定义 div，但是当我使用该标签时，我还将对齐设置为居中。居中工作，但外部样式表中的所有其他内容都不起作用。
我将添加控制器代码和视图代码以供参考。
我的问题：
如何让外部样式表和图像在我的控制器文件中为“def result”工作？
myRuby_controller.rb
class MyRubyController < ApplicationController
def index
# the first user screen is displayed:
# index.html.erb in views/myRuby directory
# This controller is executed
end
def result
# when the user presses submit, result is called
@data = params[:data] # The data text field
@field = params[:field] # the request
# check for nondigits in the data
if @data =~ /\D/
# if a nondigit, invalid.html.erb is displayed
render :action => 'invalid'
else # valid data
case @field # check the request
when "cu" then # customer data request
# Verify that customer is in the customer table
if Customer.exists?(@data)
# exists, display custdisply.html.erb
render :action => 'custdisplay'
else
# does not, display notfound.html.erb
render :action => 'notfound'
end
when "sr" then # sales rep request
if Customer.exists?(@data)
# exists, display salesrepdisplay.html.erb
render :action => 'salesrepdisplay'
else
# does not, display notfound.html.erb
render :action => 'notfound'
end
when "or" then #orders request
if Customer.exists?(@data)
# exists, display orderdisplay.html.erb
render :action => 'orderdisplay'
else
# does not, display notfound.html.erb
render :action => 'notfound'
end
when "p" then #parts request
if Customer.exists?(@data)
# exists, display partsdisplay.html.erb
render :action => 'partsdisplay'
else
# does not, display notfound.html.erb
render :action => 'notfound'
end
end # end case
end # end if valid data
end
def custdisplay
end
def salesrepdisplay
end
def orderdisplay
end
def partsdisplay
end
def notfound
end
def invalid
end
end
