SearchesIndex

Question

Rails：5.1.4

我试图搜索：immo_type或/和：地址

class SearchesController < ApplicationController

def home
    @search = Purchase.find(params[:immo_type]) 
    @purchases = Purchase.where("immo_type ILIKE ?", "%#{@search}%")
end

def index
    @purchases = Purchase.all
    @spurchases = Purchase.search_by_immo_type_and_address('@search')
end

端

从视图中我使用了simple_form_for。我不知道如何查看如何访问params [：immo_type]的内容。当我使用rails时，我发现了这条消息

无法通过＆＃39; id＆＃39; =
找到购买

我可以通过Purchase.all

查看所有购买内容

<%= simple_form_for :immo_type, url: searches_url, method: :get do |f| %>
    <%= f.hidden_field :immo_type, params[:immo_type] %>
    <%= f.input :address,  placeholder: 'Town', label: "Where" %>
    <%= f.input :immo_type,  placeholder: 'flat, house', label: "Flat or house" %>
    <%= f.button :submit, "Rechercher", class: "btn btn-danger" %>
<% end %>

这是我的模特

class Purchase < ApplicationRecord
    include PgSearch
    pg_search_scope :search_by_immo_type_and_address, against: [:immo_type, :address]

    belongs_to :user
    has_many :users, :through => :searches
end

class Search < ApplicationRecord
    belongs_to :user
    belongs_to :leasing
    belongs_to :purchase
end

我想从我的home.html.erb（根页）中搜索并在index.html.erb上显示结果

SearchesIndex

<ul>
  <% @purchases.each do |purchase| %>
    <li><%= link_to purchase.address %></li>
        maison ou appartement : <%= purchase.immo_type %><br>
        prix : entre <%= purchase.price_min %> et <%= purchase.price_max %><br>
  <% end %>
</ul>

Answer 1

所以，首先我需要使用带有主视图和索引视图的搜索控制器

class SearchesController < ApplicationController

    def home
        @searches = params[:immo_type]
    end

    def index
        @purchases = Purchase.search_by_immo_type_and_address("#{params[:purchase][:immo_type]}")
    end
end

这是我购买Pg_Search gem的模型

class Purchase < ApplicationRecord
    belongs_to :user
    has_many :users, :through => :searches

    include PgSearch
    pg_search_scope :search_by_immo_type_and_address, against: [:immo_type]
end

使用simple_form_for

的视图

<%= simple_form_for :purchase, url: searches_url, method: :get do |f| %>
            <%= f.input :address %> 
            <%= f.input :immo_type %>
            <%= f.button :submit, "Rechercher"%>
<% end %>

我希望它可以帮到你！
