Rails link_to静态页面问题

Question

我对Rails了解不多,我继承了这个项目.在过去的几天里,我一直在努力探索,"link_to"和"routes.rb".这个东西让我很生气 - 我花了一整天的时间来看待它,把一些代码粘贴到裸露的项目中,它的工作原理......但我只是不明白我到这里的错误,或者怎么去关于解决它,所以如果你有任何想法....

在我的页面_signed_in_header.html.erb我有:

<a href="../staticpages/faq">FAQ</a>

在我的routes.rb我有:

get "staticpages/faq"

我知道这是正确的,因为当我从头开始一个示例项目时,它的工作原理.

但在这个特定的项目中,我继承了我得到的错误:

NoMethodError in Staticpages#faq

Showing /home/christophecompaq/Populisto/app/views/layouts/_signed_in_header.html.erb    where line #48 raised:

undefined method `model_name' for NilClass:Class

编辑:我被要求显示我的评论控制器代码,所以在这里:

class ReviewsController < FrontEndController
respond_to :html, :json

before_filter :with_google_maps_api

def index
@review = Review.new
end

def create
@review = Review.create((params[:review] || {}).merge(:user_id => current_user.id))
if @review.save
  redirect_to landing_page, :notice =>    I18n.t('write_review.review_successfully_created')
else
  render :action => :index
end
end

def show
@review = Review.find(params[:id])
end

def edit
@review = Review.find(params[:id])
end

def update
@review = Review.find(params[:id])
if @review.update_attributes(params[:review])

else
  render :edit
end
end

def destroy
@review = Review.find(params[:id])
@review.destroy
end

def repost
@review = Review.find(params[:id])
@review.repost(current_user)
end

def reject
@review = Review.find(params[:id])
current_user.reject @review
end

end

无论如何,如果你有任何想法可能是错的,我会很高兴知道....谢谢.

克里斯托夫.

在您的路径文件中,使用此代码

get "staticpages/faq", :as => 'faq_page'

在"为"将产生2个的辅助功能:faq_page_url和faq_page_path,你可以在你的代码中使用
