openwrt中luci界面配置说明

转载自：http://blog.csdn.net/laoxiao1987/article/details/7867679

1.先在system中添加一个ipv6config
操作：先在/usr/lib/ lua/luci/controller/admin/system.lua 文件中的index页面中添加

[php] view
plain copy

print?

entry({"admin", "system", "ipv6config"}, cbi("admin_system/ipv6config"), "ipv6config", 30).dependent=false

system.lua页面全部代码

[php] view
plain copy

print?

end

end

效果如下:


2. 编写model
操作：在先在/usr/lib/ lua/luci/model/cbi/admin_system文件中的添加ipv6config.lua 文件
文件全部代码

[php] view
plain copy

print?

require("luci.sys")

require("luci.sys.zoneinfo")

require("luci.tools.webadmin")

require("luci.fs")

require("luci.config")

local m, s, o

m = Map("ipv6config", translate("ipv6config"), translate("this is ipv6 pre config"))

m:chain("luci")

s = m:section(TypedSection, "ipv6config", translate("System ipv6"))

s.anonymous = true

s.addremove = false

s:tab("general", translate("General Settings"))

o = s:taboption("general", Value, "ipv6pre", translate("ipv6 pre config"))

o.datatype = "ipv6config"

function o.write(self, section, value)

Value.write(self, section, value)

end

return m

效果：


3. 添加配置文件
操作：在/etc/config中添加ipv6config文件
代码：

[php] view
plain copy

print?

config 'ipv6config'

option 'ipv6pre' '2011:86'

ps: 注意
config 中的ipv6config文件中的ipv6confg与ipv6pre与model中ipv6config.lua两个字段的对应
