ruby与web代码结合（二）

一. 表头筛选后台控制，记录选中状态:

在controller方法里面：

params[:condition] ||=["appNumber","title","appDate","applicantName","lprs"]

@condition = params[:condition]

在html页面代码里面：

<div class="add-content">

<p>添加选项</p>

<form name="inputs" action="/patgate/search"data-remote="true" method = "post">

<ul class="pitch-on" >

<li>

<input type="checkbox"name="condition[]" value="appNumber" class="leftcheck-top checkThis" <%='checked' if (@condition.include?"appNumber")%>/>

<label for="che1" class="lefthear">专利号</label>

</li>

<li>

<input type="checkbox"name="condition[]" value="ipc" class="leftcheck-top checkThis" id="che6" <%='checked' if(@condition.include? "ipc")%>/>

<label for="che6" class="lefthear">分类号</label>

</li>

<li class="confirm-btn" id="sure">

<input type="submit" value="确定"class="btn-set" />

</li>

</ul>

</form>

</div>

二. 通过api实现查看全文和下载全文

在controller方法里面：

def ft1_test

a = PatRecord.find(params[:id])

send_data(PatApi.ft1(a.pid),:filename =>"#{a.pid}.pdf",:disposition => 'inline')

end

def ft1_test1

a = PatRecord.find(params[:id])

send_data(PatApi.ft1(a.pid),:filename =>"#{a.pid}.pdf",:disposition => 'attachment')

end

在页面显示里面，target="_blank"会在新窗口打开链接页面

<a href="/patgate/ft1_test1?id=<%=@info.id%>"target="_blank" title="" class="download-fullright">下载全文</a>

<a href="/patgate/ft1_test?id=<%=@info.id%>" target="_blank" title="" class="download-fullerright">查看全文</a>

三. 通过model定义方法缩减页面代码

在model定义方法如下，self前缀表示通过类调用：

def self.select_condition

hash ={"专利号"=>"appNumber","专利名称"=>"title","申请日"=>"appDate","专利权人"=>"applicantName","法律状态"=>"lprs",

"公开（告）号"=>"pubNumber","公开（告）日"=>"pubDate","代理人"=>"agentName","代理机构"=>"agencyName","发明人"=>"inventroName",

"分类号"=>"ipc"}

end

在页面代码做如下循环：

<% PatRecord.select_condition.each do |k,v| %>

<li>

<input type="checkbox" name="condition[]"value="<%=v%>" class="left check-top checkThis"<%='checked' if (@condition.include? v)%>/>

<label for="che1" class="lefthear"><%= k %></label>

</li>

<%end%>
