使用 Ransack 按全名搜索 [英] Searching by full name with Ransack

问题描述

我继承的一个项目上有一个 Ransack 表单，如下所示:

<%- ransack_form_options ||= {} -%><%- search_field_options ||= {} -%><%- search_field_options.merge!自动完成:关闭"，id:q"-%><div class="search-form"><%= search_form_for(@q, ransack_form_options) 做 |f|％＞<%= f.text_field search_on, search_field_options %><%= f.submit '搜索' %><%= button_tag '', class: 'cancel-search' %><%结束%>

search_on 的值为 student_first_name_or_student_last_name_or_student_email_cont.

这适用于按名字或姓氏或电子邮件进行搜索.但是如果我想搜索全名或名字或姓氏或电子邮件怎么办?我该怎么做?

解决方案

Searching full_name with ransack (first_name & last_name)

ransacker :full_name do |parent|Arel::Nodes::NamedFunction.new('CONCAT_WS', [Arel::Nodes.build_quoted(' '), parent.table[:first_name], parent.table[:last_name]])结尾

I have a Ransack form on a project I inherited that looks like this:

<%- ransack_form_options ||= {} -%>
<%- search_field_options ||= {} -%>
<%- search_field_options.merge! autocomplete: "off", id: "q" -%>

<div class="search-form">
  <%= search_form_for(@q, ransack_form_options) do |f| %>
    <%= f.text_field search_on, search_field_options %>
    <%= f.submit 'Search' %>
    <%= button_tag '', class: 'cancel-search' %>
  <% end %>
</div>

The value of search_on is student_first_name_or_student_last_name_or_student_email_cont.

This works for searching by first name or by last name or by email. But what if I want to search for full name or first name or last name or email? How can I do that?

解决方案

Searching full_name with ransack (first_name & last_name)

ransacker :full_name do |parent|
  Arel::Nodes::NamedFunction.new('CONCAT_WS', [
     Arel::Nodes.build_quoted(' '), parent.table[:first_name], parent.table[:last_name]
  ])   
end
