I'm trying to connect the payment via liqpay to the site, but I get this error:

public_key is a required field

She points to the line

<%=liqpay_button @liqpay_request %>

In show file

 <% if @place.status == false %> <p>If you have paid already, the response didn't come in yet from LiqPAY. Refresh this page later.</p> <%=liqpay_button @liqpay_request %> <% elsif @place.status == true %> <p>Payment succeeded.</p> <% else %> <p>Payment failed.</p> <% end %>

Controller code places_controller.rb

  if @place.status == false @liqpay_request = Liqpay::Request.new( :amount => @searched_film_session_price, :currency => 'UAH', :name => @place_title, :order_id => @place.id, :result_url => place_url(@place) # :server_url => liqpay_payment_place_url(@place) )

In the config / initializers / liqpay.rb file I wrote:

 Liqpay.default_options = { public_key: ENV['публичный ключ полученный при регистрации'], private_key: ENV['приватный ключ полученный при регистрации'], currency: 'UAH' }

Code payments_controller.rb

 class PaymentsController < ApplicationController protect_from_forgery :except => :liqpay_payment def liqpay_payment @liqpay_response = Liqpay::Response.new(params) @place = Place.find(@liqpay_response.order_id) @place.data = {} (Liqpay::Response::ATTRIBUTES - %w(public_key sender_phone transaction_id)).each do |attribute| @place.data[attribute] = @liqpay_response.send(attribute) end if @liqpay_response.success? @place.update_attributes!(:status => true) else @place.update_attributes!(:status => false) end redirect_to @place rescue Liqpay::InvalidResponse render text: 'Payment error', status: 500 end end

I hope you do not have time to commit.

Never, never store confidential data (passwords, keys, logins to third-party services) directly in the application code.

ENV is an object for accessing environment variables . They are the traditional means of storing configurations on 12-factor platforms like Heroku. Not perfect , but bearable.

The environment variable is the name-value pair ENV[название] #=> значение , think up the name yourself so that the expression ENV[...] looks meaningful. The same rules as when naming variables: call it so that at a glance it is clear what the meaning of the expression is.

It should be clear why ENV[ключ] did not work: there was no variable in the environment with this name and this expression returned nil .

How to set environment variables depends on the platform. Heroku has a separate section in the application settings, and locally ... there’s a whole story, storing environment variables for several applications on the same developer’s machine is not very fun, so they usually use wrappers over ENV configuration files as a "backup plan" (if not configuration file).

The path to the configuration file is .gitignore in .gitignore , so it never gets outside, but is completely absent in production, so ENV used.

I prefer figaro ( use case ), but there is also a config .

The problem was in env. I have registered the received keys directly in this field.

Update

I was misunderstood, I did not advise writing values ​​there directly, but clarified that I did it from the very beginning and it turned out to be a mistake !! I fixed it by connecting the 'figaro' gem!
