我觉得我错过了一些小细节,但我能理解这一点。
我正在尝试将simple_captcha(https://github.com/galetahub/simple-captcha)连接到他们在Rails 4上的项目:
的Gemfile:
gem 'simple_captcha', :git => 'git://github.com/galetahub/simple-captcha.git'
application_controller.rb:
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
include SimpleCaptcha::ControllerHelpers
end
.html.erb:
<%= form_for :test, url: tests_path do |f| %>
...
<p>
<%= f.simple_captcha :label => "Enter numbers..", :object => "test" %>
<%= f.submit %>
</p>
<% end %>
tests_controller.rb:
class TestsController < ApplicationController
...
def create
@test = Test.new(test_params)
if @test.valid_with_captcha?
@test.save_with_captcha
redirect_to root_path
else
redirect_to tests_path
end
end
end
rails生成simple_captcha 和 rake db:migrate ,没有错误。
显示验证码,但不会显示:无论是否正确输入验证码,仍然是重定向到 tests_path 并且文本未被保留。
如果没有验证码文本存储正确,它可以正常工作:
def create
@test = Test.new(test_params)
@test.save
redirect_to root_path
end
end
答案 0 :(得分:2)
事实证明,宝石不支持导轨4.为Rails 4工作宝石:https://github.com/pludoni/simple-captcha
我在代码中的错误应该是:
def create
@test = Test.new(captcha_params)
if @test.save_with_captcha
redirect_to root_path
else
if @test.errors.any?
redirect_to tests_path
end
end
end
private
def captcha_params
params.require(:test).permit(:id, :text, :captcha, :captcha_key)
end
