I think there is a problem with the gem or the xml folder. But it happened suddenly. The application is closed right now on rails. Can not change the link from http to https

Solution

  • Apparently, you are facing the same problem as this one:

    Ruby open-uri redirect forbidden

    It's caused because the EU central bank forced a redirection to https but openuri library is not allowing this and that's why you get this error: redirection forbidden.

    There is a gem called open_uri_redirections that will patch the openuri to allow redirections.

    https://github.com/open-uri-redirections/open_uri_redirections

    All you need to do is to:

    This should fix your issue temporarily.

    Another fix (recommended) is to monkey patch eu_central_bank gem to override

    ECB_RATES_URL at eu_central_bank/lib/eu_central_bank.rb:20

    ECB_90_DAY_URL at eu_central_bank/lib/eu_central_bank.rb:21

    constants with https instead of http.

    as follows (put this code to config/initializers/patch_eu_central_bank.rb):

    require 'eu_central_bank'
class EuCentralBank
  ECB_RATES_URL = 'https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml'.freeze
  ECB_90_DAY_URL = 'https://www.ecb.europa.eu/stats/eurofxref/eurofxref-hist-90d.xml'.freeze
end

    You might see some warnings like:

    warning: already initialized constant EuCentralBank::ECB_RATES_URL.

    You can live with it till the PR merged at the EuCentralBank gem.
