[RUBY] How to implement search functionality in Rails

This time, I will introduce how to implement the search function in Rails.



--Explain as a function to search articles on blog sites --The article table is posts --Post columns are title and body --Display search form and search results on the article list screen (index.html.erb)

Set up search routing


get 'search' => 'posts#search'

Create a search form on the article list screen


<div class="search-form">
  <%= form_with url: search_path, method: :get, local: true do |f| %>
    <%= f.text_field :keyword, value: @keyword %>
    <%= f.submit "Search" %>
  <% end %>
<div class="post-list">
  <% @posts.each do |post| %>
    <%= post.title %>
  <% end %>

Create search method

Describe the following in post.rb.


def self.search(keyword)
  where(["title like? OR body like?", "%#{keyword}%", "%#{keyword}%"])

OR outputs the article if the search keyword partially matches either title or body. (Use AND if you want to output only when both title and body are hit.)

Added search action


def search
  @posts = Post.search(params[:keyword])
  @keyword = params[:keyword]
  render "index"

This completes the search function.
