I'm trying to call API (to like https://jsonplaceholder.typicode.com/). the idea is simple click the button to show the res but I'm having trouble implementing it. What I have below is just the button calling the function and want to print it in the console.
error:
enter code here No route matches [POST] "/dashboard/fetch_action"
routes
resources :dashboard do
collection do
get :fetch_action
end
end
dashboard_controller.er
require 'faraday'
def index
end
def fetch_action
response = Faraday.get 'https://jsonplaceholder.typicode.com/posts/1'
puts response
# return response
end
index.html.erb
<%= button_to "fetch action", fetch_action_dashboard_index_path, class: "btn btn-warning" %>
Thank you

Error (when clicking the link_to redirects to dashboard/fetch-action with the following error):
DashboardController#show is missing a template for this request format and variant. request.formats: ["text/html"] request.variant: [] NOTE! For XHR/Ajax or API requests, this action would normally respond with 204 No Content: an empty white screen. Since you're loading it in a web browser, we assume that you expected to actually render a template, not nothing, so we're showing an error to be extra-clear. If you expect 204 No Content, carry on. That's what you'll get from an XHR or API request. Give it a shot.
First, in your terminal, run rake routes to print out the routes in your app. Post that output here. But you’ll want to check the output of that command for the fetch_action_dashboard_index_path you’re using in the button - is that the correct path?
I assume it’s not. And there is a simpler way to declare one route. What you’re doing with the resources declaration in your route is configuring routes for the index, show, create, update and delete actions for The dashboard controller. The below line in your routes.rb file will setup just the fetch_action route and name it “dashboard_fetch_action”
get '/dashboard/fetch-action', to: 'dashboard#fetch_action', as: 'dashboard_fetch_action'
Second; use link_to instead of button_to to ensure you make a GET request. The btn classes you’re applying will style that link to look like a button anyway and an a tag is more semantically correct than button (because you want to GET) so use:
<%= link_to "fetch action", dashboard_fetch_action_path, class: "btn btn-warning" %>
Finally make sure you have a file in app/views/dashboard/fetch_action.html.erb which will render the API response as HTML. This content (or similar) will achieve that.
<%= @response =>
And, in your fetch_action action in the dashboard controller. Instead of response = Faraday..., use @response = Faraday.... That way the response object can be accessed in the view HTML (that’s what the @ signifies)
def fetch_action
@response = Faraday.get 'https://jsonplaceholder.typicode.com/posts/1'
end
