Answer 1

写代码要小心，往往每个字符都很重要：

flash[:notice] = "Article was submitted succsefully"

space 导致解析变得不稳定。

您的代码被解释为：

flash([:notice]) = "Article was submitted succsefully"

无效 Ruby。

另外："succsefully" 拼写不正确。希望你还没有发货！

尝试：

respond_to do |format|
      if @article.save
        format.html { redirect_to_article_path(@article), notice: "Article was submitted succsefully" }
        format.json { head :no_content }
      else
        format.html { render :new }
        format.json { render json: @article.errors, status: :unprocessable_entity }
      end
 end
