Question

에서 PDF를 생성합니다

class WorkOrder < ActiveRecord::Base 
    self.table_name = "work_orders" 
    set_primary_key "id" 
    has_many :work_order_details 
    belongs_to :type 
    belongs_to :client 
def get_action_name(id) 
    n = Action.find(id) 
    logger.warn("!!!!!!!!!!!!!!! AAAA !!!!!!!!!!!!!!!!!!!") 
    logger.warn(n.name) 
    n.name 
    end 

    def get_price_name(id) 
    n = ActionDetail.find_by_action_id(id) 
    logger.warn("!!!!!!!!!!!!!!! AAAA !!!!!!!!!!!!!!!!!!!") 
    n.price 
    end 

    def get_master_name(id) 
    n = Master.find(id) 
    logger.warn("!!!!!!!!!!!!!!! AAAA !!!!!!!!!!!!!!!!!!!") 
    a = n.lastname + " " + n.firstname 
    a 
    end 
end 



class WorkOrderDetail < ActiveRecord::Base 
    self.table_name = "work_order_details" 
    set_primary_key "id" 
    belongs_to :master 
    belongs_to :action 
    belongs_to :work_order 
end 



class Action < ActiveRecord::Base 
    self.table_name = "actions" 
    set_primary_key "id" 
    belongs_to :specialization 
    has_many :action_details 
    has_many :work_order_details 
end 



class Master < ActiveRecord::Base 
    self.table_name = "masters" 
    set_primary_key "id" 
    has_many :master_specializations 
    has_many :work_order_details 
end 

나는 그런보기 같은 PDF를 생성 할 수 있어야

%table.zebra 
    %tr 
    %th id 
    %th Услуга 
    %th Мастер 
    %th Стоимость 
    %th Бонус 
    %th 
    %th 
    %th 
    -if @work_order.work_order_details.kind_of?(Array) 
    - @work_order.work_order_details.each do |work_order_detail| 
     %tr{:class => cycle("zebra-stripe zebra-grey zebra1", "zebra-stripe zebra-grey zebra2")} 
     %td= work_order_detail.work_order_id 
     %td= work_order_detail.get_action_name(work_order_detail.action_id) 
     %td= work_order_detail.get_master_name(work_order_detail.master_id) 
     %td= work_order_detail.get_price_name(work_order_detail.action_id) 
     - count = count + work_order_detail.get_price_name(work_order_detail.action_id) 
     %td= work_order_detail.bonus 
    Общая сумма: 
    = count 
    -else 
    %tr{:class => cycle("zebra-stripe zebra-grey zebra1", "zebra-stripe zebra-grey zebra2")} 
     %td= @work_order.work_order_details.work_order_id 
     %td=# @work_order.work_order_details.get_action_name(@work_order.work_order_details.action_id) 
     %td= @work_order.work_order_details.master_id 
     %td= @work_order.work_order_details.bonus 
    = link_to 'Добавить услугу', new_work_order_detail_path 

이 작업의 고급하지만,있어 내가 할 때 이러한 PDF :

pdf.font_families.update(
     "Verdana" => { 
     :bold => "C:/verdanab.ttf", 
     :italic => "C:/verdanai.ttf", 
     :normal => "C:/verdana.ttf" }) 
    pdf.font "Verdana", :size => 10 
pdf.text "Заказ-наряд ##{@work_order.id}", :size => 20, :style => :bold 
pdf.text "##{@work_order.date_of_work_start}", :size => 8, :style => :bold 

pdf.move_down(30) 




items = @work_order.work_order_details.map do |item| 
    [ 
    item.work_order_id 
    item.get_action_name(item.action_id) 
    item.get_master_name(item.master_id) 
    item.get_price_name(item.action_id) 
    item.bonus 
    ] 
end 



pdf.table items, :border_style => :grid, 
    :row_colors => ["FFFFFF","DDDDDD"], 
    :headers => ["id", "Услуга", "Мастер", "Стоимость"] 


pdf.move_down(10) 

그것은 ... 오류의 나에게주는

컨트롤러의 방법

def show 
    @work_order = WorkOrder.find(params[:id]) 
    @work_order_details = WorkOrderDetail.find_all_by_work_order_id(@work_order.id) 
    respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @work_order } 
     format.pdf { render :layout => false } 
    end 
    end 

오류 발생 :

C:/_Projects/CarService/app/views/work_orders/show.pdf.prawn:18: syntax error, unexpected tIDENTIFIER, expecting ']' 
    item.get_action_name(item.action_id) 
     ^
C:/_Projects/CarService/app/views/work_orders/show.pdf.prawn:22: syntax error, unexpected ']', expecting keyword_end 
C:/_Projects/CarService/app/views/work_orders/show.pdf.prawn:34: syntax error, unexpected keyword_ensure, expecting keyword_end 
C:/_Projects/CarService/app/views/work_orders/show.pdf.prawn:36: syntax error, unexpected $end, expecting keyword_end 

이 어떻게 다른 테이블에서 fertching 데이터와 PDF를 할?

또한 그냥

items = @work_order.work_order_details.map do |item| 
    [ 
    item.work_order_id 
    item.get_action_name(item.action_id) 
    item.get_master_name(item.master_id) 
    item.get_price_name(item.action_id) 
    item.bonus 
    ] 
end 

나는 쉼표의 잊지 참조

@work_order.work_order_details.each do |item| 
    pdf.text item.get_action_name(item.action_id) 
end 

모든 확인

Answer 1

ㅎ입니다) 을 쓸 때. 로 :

items = @work_order.work_order_details.map do |item| 
    [ 
    item.work_order_id, 
    item.get_action_name(item.action_id), 
    item.get_master_name(item.master_id), 
    item.get_price_name(item.action_id), 
    item.bonus 
    ] 
end
