how search with simple_form_for and pg_search gem - pg-search

Question

Rails : 5.1.4
I'm trying to search on :immo_type or/and :address
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
end
From the view i used simple_form_for. I don't know how to see how to access the content of params[:immo_type]. When i used rails, i've this message
Couldn't find Purchase with 'id'=
I can see all my purchases with Purchase.all
<%= 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 %>
Here my models
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
I would like to search from my home.html.erb (root pages) and display the result on my index.html.erb
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

So, first i need to work with a search controller with the home and index views
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
This is my purchase model with Pg_Search gem
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
And the view with simple_form_for
<%= simple_form_for :purchase, url: searches_url, method: :get do |f| %>
<%= f.input :address %>
<%= f.input :immo_type %>
<%= f.button :submit, "Rechercher"%>
<% end %>
I hope it can help you !
