class WeatherController

`WeatherController`

Single-resource controller that powers the weather search page.

Routes

GET / → index (root) GET /weather/search → search → redirects to root with address param

Flow

User lands on the root page (empty search).
Submitting the search form hits search, which redirects back to root with the +address+ query parameter.
index detects the address, calls {Services::Application::WeatherByAddress} to geocode and fetch weather, and assigns +@result+ for the view.
On error, +@error+ is set and shown in the +_error+ partial.

Public Instance Methods

index ()

Source

   # File app/controllers/weather_controller.rb
29 def index
30   @address = params[:address].to_s.strip
31   return unless @address.present?
32 
33   @result = Services::Application::WeatherByAddress.new.call(@address)
34 rescue StandardError => e
35   @error = e.message
36 end

Renders the main weather page.

When +params+ is present, delegates to {Services::Application::WeatherByAddress} and assigns:

+@result+ — a {Services::Application::WeatherByAddress::Result} with location, current weather, hourly and daily forecasts.
+@error+ — error message string if the service raises.
+@address+ — the raw search string (always set).

search ()

Source

   # File app/controllers/weather_controller.rb
40 def search
41   redirect_to root_path(address: params[:address])
42 end

Accepts the search form submission and redirects to +root_path+ with the address as a query parameter, keeping the URL bookmarkable.
