生成动态内容文件的木偶erb模板:
<%
if @interfaces.count(',') > 0 then
counter = 0
@interfaces.split(',').each do |int|
next if int == "lo"
if has_variable?("ipaddress_#{int}")
ip = scope.lookupvar("ipaddress_#{int}")
mask = scope.lookupvar("netmask_#{int}")
cidr = scope.call_function('netmask_to_masklen',["#{mask}"])
cidr_to_n = scope.call_function('cidr_to_network',["#{ip}/#{cidr}"])
if ip =~ /192.168.0/
x = ip
$i1 = int
$c_to_n1 = cidr_to_n
else
$y = ip
$i2 = int
$c_to_n2 = cidr_to_n
end
end
end
end -%>
ip route add <%= $c_to_n1 %>/<%= $cidr %> dev <%=$i1%> src <%=$x%> table 192.168.0_RT
ip route add default via 192.168.0.1 dev <%=$i1%> table 192.168.0_RT
ip route add <%= $c_to_n2 %>/<%= $cidr %> dev <%=$i2%> src <%=$y%> table 192.168.168_RT
ip route add default via 192.168.168.1 dev <%=$i2%> table 192.168.168_RT
ip rule add from <%= $x %>/32 table 192.168.0_RT
ip rule add from <%= $y %>/32 table 192.168.168_RT
就目前而言,代码正在按预期工作,但是,如果我在if / else之间放置行(ip route ...),则所有内容均打印在同一行上,而没有换行符。 所以主要的问题是如何使代码看起来更简洁:)
答案 0 :(得分:0)
如果我对您的理解正确,那么要在if块之间呈现这些行,您需要添加html换行符
标记,然后将字符串标记为#html_safe或在视图中使用“ #h”帮助器。
例如:
<% (1..4).each do |i| %>
<% if i.even? %>
<%= h "#{i} is even<br>" %>
<% else %>
<%= h "#{i} id odd<br>" %>
<% end %>
<% end %>
应该创建HTML呈现这样的:
1 is odd
2 is even
3 is odd
4 is even
