在用户和嵌套路线后编辑link_to

Question

I'm trying to construct a link for a object that's nested behind a user and shopmain routes: user>shompmain>shopaddress

I can't get the show/edit/delete links working.

<%= link_to 'Show', user_shopmain_shopaddress_path(shopaddress.shopmain, shopaddress), :class => "btn btn-primary btn-sm" %>
<%= link_to 'Edit', edit_user_shopmain_shopaddress_path(shopaddress.shopmain, shopaddress), :class => "btn btn-primary btn-sm" %>
<%= link_to 'Delete', user_shopmain_shopaddress_path(shopaddress.shopmain, shopaddress), method: :delete, data: { confirm: 'Are you sure?' }, :class => "btn btn-danger btn-sm" %>

I get this error that reads something like. It seems like I'm missing the id for the shopaddress for some reason.

No route matches {:action=>"show", :controller=>"shop/shopaddresses", :id=>nil, :shopmain_id=>#<Shop::Shopaddress id: 2, shopadrsline1: "Civic Place", shopadrsline2: "Box 888", shopadrscity: "Toronto", shopadrsprovince: "ON", shopadrspostalcode: "N0N1V0", shopmain_id: 2, created_at: "2016-01-17 03:38:47", updated_at: "2016-01-17 03:38:47">, :user_id=>#<Shop::Shopmain id: 2, shopname: "Eastwood", shoptagline: "Testing", user_id: 1, created_at: "2016-01-17 03:30:01", updated_at: "2016-01-17 03:30:01">} missing required keys: [:id]

My routes file readslike

Rails.application.routes.draw do

    # Devise Authetication
    devise_for :users
    devise_for :admins

    # Website Pages
    root 'website/page#index'

    # Backend Shop Module
    resources :users do
        scope module: "shop" do
            resources :shopmains do
                resources :shopdetails
                resources :shopaddresses
                resources :shophours
            end
        end
    end

end

My shopaddresses controller looks like:

class Shop::ShopaddressesController < ApplicationController

    # Security and Layouts
    before_filter :authenticate_user!
    layout 'layouts/shop/application.html.erb'
    before_action :set_shopaddress, only: [:show, :edit, :update, :destroy]

        shopmain = Shop::Shopmain.find(params[:shopmain_id])

        shopmain = Shop::Shopmain.find(params[:shopmain_id])
        @shopaddress = shopmain.shopaddresses.find(params[:id])
    end

    # Create a New Shop Address
    def create

            format.html { redirect_to user_shopmain_shopaddresses_path, notice: 'Comment for Shopmain was Successfully Created.' }
            format.json { render action: 'show', status: :created, location: @shopaddress }
            else
                format.html { render action: 'new' }
                format.json { render json: @shopaddress.errors, status: :unprocessable_entity }
            end
        end
    end

            format.html { redirect_to user_shopmain_shopaddresses_path, notice: 'Comment for Shopmain was Successfully Updated.' }
            format.json { head :no_content }
            else

                format.json { render json: @shopaddress.errors, status: :unprocessable_entity }
            end
        end
    end

    # Delete Shop Address
    def destroy
        @shopmain = Shop::Shopmain.find(params[:shopmain_id])
        @shopaddress = @shopmain.shopaddresses.find(params[:id])
        @shopaddress.destroy
        respond_to do |format|
            format.html { redirect_to user_shopmain_shopaddresses_path, notice: 'Comment for Shopmain was Successfully Deleted.'  }
            format.json { head :no_content }
        end
    end

    private

    # Common Constrainsts
    def set_shopaddress
        @shopaddress = Shop::Shopaddress.find(params[:id])
    end

    # Strong Params Whitelist
    def shopaddress_params
        params.require(:shop_shopaddress).permit(:shopadrsline1, :shopadrsline2, :shopadrscity, :shopadrsprovince, :shopadrspostalcode, :shopmain_id)
    end

I'm surprised you said your show link works as it clearly cannot work. :) Your route helpers expect three parameters, not two - you are missing user id. So it should be:

<%= link_to 'Show', user_shopmain_shopaddresses_path(current_user, shopaddress.shopmain, shopaddress), :class => "btn btn-primary btn-sm" %>
