希望我连续的问题对任何人都没有问题,我想请你帮忙,如何实现从一个表格创建两个模型。
两个相关的模型是
class Employee < ActiveRecord::Base
attr_accessible :name
belongs_to :company
attr_accessible :company_id
end
class Company < ActiveRecord::Base
attr_accessible :name
has_many :employees
end
当我创建员工并且输入公司尚不存在时,我想要创建一家公司。没有“当公司不存在时”的要求,这是我的代码:
employees/_form.html.erb
<%= simple_form_for(@employee) do |f| %>
<%= simple_form_for(@company) do |cf| %>
<%= f.input :name, label: 'Employee Name', :required => true %>
<%= cf.input :title, label: 'Company Name', :required => true %>
<% end %>
<% end %>
和employees_controller.rb
def new
@employee = Employee.new
@company = Company.new
end
[...]
def create
@employee = Employee.new(params[:employee])
@company = Company.new(params[:company])
@employee.company_id = params[:company_id]
respond_to do |format|
if @employee.save
format.html { redirect_to @employee, notice: 'Employee was successfully created.' }
format.json { render json: @employee, status: :created, location: @employee }
else
format.html { render action: "new" }
format.json { render json: @employee.errors, status: :unprocessable_entity }
end
end
end
这种员工和公司之间的某种关联(员工“持有”公司 ID)但它并没有创建(或者,如果我理解得很好,实际上并没有拯救)公司。
If I go on and add @company.save
before the id assignment, everything seems okay. Is it, however? Shouldn't I render the new company form
and have everything saved after that is submitted?
I have been searching online all day for the solution but in every case the implementation was performed the opposite way: How to create a bunch of employees from a new company form.
