I have a Rails app where I have a partial that I want a dropdown in so when a user is selected it will do a get method to the urls /timecards/:user_id which will be the controller's show method passing in the User's id field. 我在我的道路上遇到了困难form_tag,可以使用一些帮助。
这是我的部分观点:
<%= form_tag timecard_path, :method => :get do %>
<%= select_tag options_from_collection_for_select(User.employee.order("username ASC"), :id, :username) %>
<%= submit_tag "View Employee", class: "btn btn-primary" %>
<% end %>

从耙路线我得到以下输出:

这是我的控制器:timecards_controller.rb

@clock_events = ClockEvent.includes(:user).search(params[:search])

format.html do
@clock_events = @clock_events.paginate(:per_page => params[:per_page] || 20, :page => params[:page]).order('users.username asc').order('clock_in desc')
end
format.csv { send_data ClockEvent.to_csv(@clock_events.order('users.username asc').order('clock_in desc')) }

所以我相信我正在正确地调用路径,form_tag但是当我加载页面时,我收到错误:No route matches {:action=>"show", :controller=>"timecards"}即使 timecards_controller 中有一个显示操作。
我认为我必须form_tag为显式网址设置一些内容并以某种方式传入:id在参数中用户的 。但我对如何做到这一点有些困惑。
所以总结一下。当我有下拉菜单时,我选择一个用户,单击“查看员工”,然后应该转到 timecards_controller.rb 中的显示操作,网址为 /timecards/3(作为示例)。我以前从未以这种方式使用过 form_tag,因此传递路径或显式 url 对我来说有点陌生。
最简单的解决方法是将表单更改为一堆链接。
<%= User.employee.order("username ASC").each |u| %>
<%= link_to u.username, timecard_path %>
<% end %>

否则,您可以使用 Javascript 简单地使表单重定向:
<%= form_tag timecodes_path, :method => :get, :id => 'timecode_employee' do %>
<%= select_tag options_from_collection_for_select(User.employee.order("username ASC"), :id, :username) %>
<%= submit_tag "View Employee", class: "btn btn-primary" %>
<% end %>

$("#timecode_employee").submit(function(e){
var form = $(this);
// redirect to timecards/:id
window.location = form.attr('action') + form.find('select').val();
e.preventDefault();
});

通过添加底层 TimeCard 模型,可以从根本上改进您的设计。
这是一个非常常见的案例,可以告诉您原因:
客户决定他们希望经理每个月都在考勤卡上签字。
哦,天哪。现在我们需要获取ClockEvents该范围内的所有内容并在每个内容上更新“clock_events.state”。
但随后客户也想知道谁签了卡。所以你添加一个clock_events.signed_off_by_id并更新所有的时钟事件。然后他们希望三位经理签字,等等。
请注意,这是一个固执的通用示例。
class ClockEvent < ActiveRecord::Base
enum status: [:clocked_in, :clocked_out]
has_many :users
belongs_to :time_card
end
class TimeCard < ActiveRecord::Base
belongs_to :user
has_many :clock_events
accepts_nested_attributes_for :clock_events
end
class User < ActiveRecord::Base
has_many :time_cards
has_many :clock_events, through: :time_cards

TimeCard 可能会每月自动发放,或者如果您永远不想更改,而只是坚持每个用户一张 TimeCard。让我们在这里走一些传统路线:
resources :time_cards
end
resources :clock_events do
end
resources :users, shallow: true do
resources :clock_events do
end
resources :time_cards do
end

现在想象一下我们有一个经典的打孔卡时钟。
我们会打卡:
POST /clock_events { user_id: 1, time_card_id: 5 }

并打出:
PATCH /clock_events/1 { status: :clocked_out }

这就是你的休息。
我们为每个用户的时间卡和 clock_events 嵌套了路由:
GET /users/1/time_cards
GET /users/1/clock_events

从我们可以选择构建一个专用的,UserTimeCardController或者我们可以通过 TimeCardsController 中的用户 id 参数来确定范围。
class TimeCardsController
def index
@time_cards = TimeCard.all
@time_cards = @time_cards.where(user: params[:user_id]) if params[:user_id]
@users = scope.all
end
end

但是想象一下,如果我们希望经理能够过滤他在索引中看到的员工数量 - 一个好的架构应该是这样的:
class TimeCardsController
def index
@time_cards = TimeCard.all
@time_cards = @time_cards.where(user: params[:user_id]) if params[:user_id]
if params[:filters]
@time_cards = @time_cards.search(params[:search])
end
end
end

在我们的索引页面上,我们将添加一个这样的表单:
<%= form_tag(time_cards_path, method: :get) %>
<%= select_tag options_from_collection_for_select(User.employee.order("username ASC"), :id, :username), multiple: true %>
<%= submit_tag "Filter", class: "btn btn-primary" %>
<% end %>
