我的站点在我的开发机器上工作，部署到heroku我在日志中得到这个:

这是我的路由文件的一部分:

@hints = Hint.where("sentence LIKE ? AND user_id =?", "%#{params[:word]}%", current_user.id) #.order("LENGTH(sentence) ASC").limit(5)

@hint = Hint.find(params[:id])
@hint.destroy
respond_to do |format|
format.html { redirect_to hints_url }
format.json { head :no_content }
end
end
end
我尝试删除这一行:render :layout => 'layouts/found_sentences'并取消注释:
#respond_to do |format|
# format.html # find_sentences.html.erb
# format.json { render json: @hints }
#end
但这不起作用。接下来我应该尝试什么?
要求更新:[~/rails_projects/blt]$ls app/views/{application,hints}
ls: app/views/application: No such file or directory
app/views/hints:
_form.html.erb edit.html.erb found_sentences.html.erb index.html.erb new.html.erb show.html.erb
[~/rails_projects/blt]$cd app
[~/rails_projects/blt/app]$cd views
[~/rails_projects/blt/app/views]$cd application
bash: cd: application: No such file or directory
[~/rails_projects/blt/app/views]$ls
content dictionary_entries home lessons users
devise hints layouts user_mailer
[~/rails_projects/blt/app/views]$
问题是在index的行动，而不是在find_sentences。添加index.html.erb到app/views/hints
这不是问题所在。
请阅读完整的对话，看看我们如何定位实际问题。
用户正在使用mac，其文件系统不区分大小写。模板目录用大写H表示提示(app/views/Hints)。Heroku使用linux和区分大小写的文件系统，这会导致错误。
