我正在尝试安装wicked_pdf，以便在我的Rails应用程序上生成2个用户之间的预填充 Contract .
我觉得我已经正确安装了wicked_pdf，但是我收到了“ActionController :: UnknownFormat”错误 .
我做了什么 ：
# Gemfile
gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'
有或没有取消注释'exe ...'行（一个接一个），我仍然得到错误：
# initializers/wicked_pdf.rb
WickedPdf.config = {
# Path to the wkhtmltopdf executable: This usually isn't needed if using
# one of the wkhtmltopdf-binary family of gems.
# exe_path: '/usr/local/bin/wkhtmltopdf',
# or
# exe_path: Gem.bin_path('wkhtmltopdf-binary', 'wkhtmltopdf')
# Layout file to be used for all PDFs
# (but can be overridden in `render :pdf` calls)
# layout: 'pdf.html',
}
我的控制器：
#bookings_controller.rb
class BookingsController < ApplicationController
def show
@booking = Booking.find(params[:id])
respond_to do |format|
format.html
format.pdf do
render pdf: "test_wicked_pdf"
end
end
authorize @booking # For Pundit
end
当我去localhost：3000 / bookings / 135时渲染HTML正在工作......
# bookings/show.html.erb
<h1>PDF test</h1>
...当我在控制器中注释掉“#format.html”时，不是PDF
# bookings/show.pdf.erb
<h1>PDF test</h1>
非常感谢提前
