2類和設計

Question

用戶的Rails這實在是一個小白的問題，但我已經搜索了很多，並沒有發現什麼對我的解決方案。

A具有與2種用戶應用。客戶和承包商。我嘗試設計建立兩個，我可以簽署承包商的工作，並與客戶一樣都在db等好，但有些事情是行不通的。

首先，我不能在登錄窗體中添加承辦公司名稱（我已經做了很多，但知道不工作），我做遷移等，但不能顯示在表格符號。我沒有錯誤，只是沒有表演。

最後，我儘量讓客戶生成項目，並有他的身份證與

current_cutomer.projects.build(project_params) 

，我得到一個關於參數等

Sry基因的錯誤，我的英語

projects_controller。 rb

class ProjectsController < ApplicationController 

before_action :find_project, only: [:show, :quote, :edit, :update] 
before_action :authenticate_cus!, except: [:index, :show] 

def home 
end 

def index 
@projects = Project.all.order("created_at DESC") 
end 

def show 
end 

def quote 
end 

def new 
@project = current_customer.projects.create 
end 

def create 
@project = current_customer.projects.create(project_params) 


if @project.save 
    redirect_to @project 
else 
    render 'new' 
end 
end 

def edit 
end 

def update 
if @project.update(project_params) 
    redirect_to @project 
else 
    render 'edit' 
end 
end 

private 

def project_params 
params.require(:project).permit(:name, :description, :date, :budget, :category_id, :location, :image) 
end 

def find_project 
    @project = Project.find(params[:id]) 
end 
end

形式爲承包

<h2>Sign up</h2> 

<%= simple_form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %> 
<%= f.error_notification %> 
<h1>New Contractor</h1> 
<div class="form-inputs"> 
    <%= f.input :company_name, required: true, autofocus: true %> 
    <%= f.input :email, required: true %> 
    <%= f.input :password, required: true, hint: ("#{@minimum_password_length} characters minimum" if @minimum_password_length) %> 
    <%= f.input :password_confirmation, required: true %> 
</div> 

<div class="form-actions"> 
    <%= f.button :submit, "Sign up" %> 
</div> 
<% end %> 

<%= render "contractors/shared/links" %> 

Answer 1

最後我做了兩個用戶模型色器件和應用控制器我寫

devise_group :user, contains: [:customer, :company] 

現在我可以用

@project = current_user.projects.build(project_params) 

一切都好，只需要給予權限。
