好的,当我试图在使用脚手架生成的主控制器中渲染它们时,这些仪表板页面最初起作用。我选择尝试将它们分成自己的控制器。我正在从另一个应用程序复制大部分内容,但它是rails 3,我使用的是rails 4.此外,我只有一个模型order.rb,其中生成图表的查询驻留。
routes.rb中:
Rails.application.routes.draw do
resources :orders do
collection do
get :search, as: 'search'
end
end
namespace :dashboards do
get 'chart_needby_monthly'
get 'chart_total_orders_by_qty'
get 'chart_qty_monthly'
end
root 'orders#landing'
end
控制器:
class DashboardsController < ApplicationController
def chart_needby_monthly
logger.info 'I’m inside the controller function, the value of params is: #{params([:dyear])}'
year = ((params[:dyear]).gsub(/\D/,'')
logger.info 'After assignmnet, dyear is: #{dyear}'
@chart_data_one = Order.search_one(year)
end
def chart_total_orders_by_qty
@chart_data_two = Order.search_two(year)
end
def chart_qty_monthly
@chart_data_three = Order.search_three(year)
end
private
def chart_needby_monthly_params
params.require(:dyear)
end
end
chart_needby_monthly.html.erb
<div align = "center">
<h3>Please Choose the Year for the Dashboard</h3>
</div>
<div align = "center">
<%= form_tag dashboards_chart_needby_monthly_path, method: :get do %>
<%= text_field_tag :dyear, (params[:dyear] || Time.now.year.to_s), :class => "search-query span3", :placeholder => "Enter the Year", :autofocus => "autofocus", :datatoggle => "tooltip", :title => "Enter a Year" %>
<% end %>
</div>
</div>
</br>
</br>
<%= column_chart @chart_data_one, {library: {hAxis: {title: "Month"}, vAxis: {title: "Number of Orders"}, title: "Need By (Month/Year)"}} %>
因此,当我尝试导航到该页面时,我得到了500页出错的页面。
我知道我在这里缺少一些东西。
这是意图:
用户在页面顶部的text_field中输入一年并点击进入,然后重新呈现输入年份的页面;它默认为第一次渲染时的当前年份,以便默认情况下将某些内容传递给模型中的查询。
我在3个不同的页面上有三个不同的图表。
以下是服务器日志的输出:
[INFO](null):0(null)():( null):在2015-05-18 10:06:06 -0700开始获取10.63.134.10 GET“/ dashboards / chart_needby_monthly”
所以它试图去做,但它似乎永远不会真正到达控制器。我一直试图解决这个问题4天,我似乎无法弄清楚我做错了什么。
哦,这是路线rake:
Prefix Verb URI Pattern Controller#Action
search_orders GET /orders/search(.:format) orders#search
orders GET /orders(.:format) orders#index
POST /orders(.:format) orders#create
new_order GET /orders/new(.:format) orders#new
edit_order GET /orders/:id/edit(.:format) orders#edit
order GET /orders/:id(.:format) orders#show

PUT /orders/:id(.:format) orders#update
DELETE /orders/:id(.:format) orders#destroy
dashboards_chart_needby_monthly GET /dashboards/chart_needby_monthly(.:format) dashboards#chart_needby_monthly
dashboards_chart_total_orders_by_qty GET /dashboards/chart_total_orders_by_qty(.:format) dashboards#chart_total_orders_by_qty
dashboards_chart_qty_monthly GET /dashboards/chart_qty_monthly(.:format) dashboards#chart_qty_monthly

答案 0 :(得分:1)
您应该尝试在开发环境中重现这一点,这样您就可以看到堆栈跟踪,告诉您到底出了什么问题而不仅仅是出现服务器错误。
在您的控制器操作中,您执行此操作:
year = ((params[:dyear]).gsub(/\D/,'')
但是有一个未公开的括号,所以你最有可能得到语法错误。将其更改为有希望修复它:
year = (params[:dyear]).gsub(/\D/, '')
或者甚至更好,因为你不需要那些初始括号:
year = params[:dyear].gsub(/\D/, '')
但是你在其他控制器操作中又犯了一个错误。在chart_total_orders_by_qty
和chart_qty_monthly
中,您指的是未定义的本地变量year
。最简单的解决方法是将其提取到自己的方法中:
class DashboardsController < ApplicationController
def chart_needby_monthly
@chart_data_one = Order.search_one(year)
end
def chart_total_orders_by_qty
@chart_data_two = Order.search_two(year)
end
def chart_qty_monthly
@chart_data_three = Order.search_three(year)
end
private
def year
params[:dyear].gsub(/\D/, '')
end
end
