我有一个关键字搜索页面,其结果显示在表格中。此表中的一个字段是一个url,当字段中包含一个字段时,我希望将其显示为可点击链接但是我无法使其工作,当单击链接时,它会再次查询搜索。我认为问题是由于搜索控制器中的def处理关键字搜索视图。有人可以帮忙吗?
以下是包含结果表的关键字搜索视图:
<!-- Index of all Courses -->
<% provide(:title, "Courses Page") %>
<!--Breadcrumbs -->
<br>
<%= link_to "Back", :back %><br><br>
<!--Page Contents -->
<div class ="row">
<h1>Degrees Offered</h1>
<%= image_tag "line.png" , :alt => "line break"%>
</div>
<div class ="row">
<!-- Form for Keyword Search, to query database for University courses. It is hidden so as to not appear as a search on the page -->
<div class = "hidden">
<%= form_tag(keywordsearch_path, :method => "get", id: "search-data") do %>
<%= text_field_tag :search, params[:search], placeholder: "Search course" %>
<%= submit_tag "Search" %>
<% end %>
</div>
<% if @search_degree != nil %>
<% end %>
<% if @search_degree != nil %>
<table border="1" class="table">
<thead>
<tr>
<th>University Name</th>
<th>Course Name</th>
<th>Duration</th>
<th>Qualification</th>
<th>Entry Requirements</th>
<th>Course Page</th>
</tr>
</thead>
<tbody>
<% @search_degree.each do |degree| %>
<tr>
<td><%= degree.uname %></td>
<td><%= degree.cname %></td>
<td><%= degree.duration %></td>
<td><%= degree.qualification %></td>
<td><%= degree.entry %></td>
<td> <a href=<% degree.url %>>View course page on University Website</a></td>
</tr>
<% end %>
</tbody>
</table>
<% end %>
</div>
以下是定义关键字搜索的搜索控制器的一部分:
def keywordsearch
@search = Degree.all.select(:uname, :cname, :ucas, :duration, :qualification, :entry).distinct.order(id: :ASC)
if params[:search]
@search_degree = Degree.search(params[:search]).order('uname ASC')
end
end
所有这些链接都是可点击的,但不是将我带到正确的网址,而是重新搜索。
答案 0 :(得分:0)
尝试此操作而不是硬编码<a> tag
:
<%= link_to 'View course page on University Website', degree.url %>
您还可以发布网址样本吗?请务必包含协议(例如http://..。)
