Answer 1

放物品PARAMS之外的创建

class ArticlesController < ApplicationController 

    def new 
    @article = Article.new 
    end 

    def create 
    @article = Article.new(article_params) 
    if @article.save 
     flash[:notice] = "Article was submitted succsefully" 
     redirect_to (@article) 
    else 
     render :new 
    end 
    end 

    # this is show method 
    def show 
    @article = Article.find(params[:id]) 
    end 

    private 
    def article_params 
     params.require(:article).permit(:title, :description) 
    end 
end

我想创建行动没有正确关闭，因此你有在create动作中的article_params方法，删除最后一行的'end'，并向create动作添加一个'end'，它的语法错误。这样

class ArticlesController < ApplicationController 
    def new 
    @article = Article.new 
    end 

     def create 
     @article = Article.new(article_params) 
     if @article.save 
      flash[:notice] = "Article was submitted succsefully" 
      redirect_to (@article) 
     else 
      render :new 
     end 
     end 

     private 
     def article_params 
      params.require(:article).permit(:title, :description) 
     end 
     end
