Cannot access Rails view helpers methods when using with JBuilder #261

Open vizcay opened 4 years ago

vizcay commented 4 years ago

According to documentation, gon supports JBuilder templates out of the box. In JBuilder, it is possible to use Rails view helpers methods without further configuration, but when trying to render them with gon.jbuilder it fails.

For example:

module ApplicationHelper
  def bigdecimal_to_cents(value)
    (value * 100).to_i if value
  end
end
undefined method `bigdecimal_to_cents' for #<Gon::Jbuilder::Parser:0x00007f943467f2f8>
