（Rails Newbie here）我有两种型号Usuario和Ficha。 Usuario与Ficha有一个联合。
以下是我的模特：
class Ficha < ApplicationRecord
belongs_to :user
belongs_to :usuario
end
class Usuario < ApplicationRecord
belongs_to :user
has_one :ficha, :dependent => :destroy
end
这是Usuario控制器：
class UsuariosController < ApplicationController
before_action :authenticate_user!
def index
@usuarios = Usuario.all
@usuario_last = Usuario.last(10)
@usuario_rev = @usuario_last.reverse
@user_count = current_user.usuarios
#Search
@usuario_search = if params[:term]
Usuario.where("name ~* ?", params[:term])
else
Usuario.all
end
@usuario_pag = @usuario_search.paginate(:page => params[:page], :per_page => 10)
end
def show
@usuario = Usuario.find(params[:id])
end
def new
@usuario = current_user.usuarios.build
end
def create
@usuario = current_user.usuarios.build(usuario_params)
@usuario.save
redirect_to @usuario
end
def edit
@usuario = Usuario.find(params[:id])
end
def update
@usuario = Usuario.find(params[:id])
if @usuario.update(usuario_params)
redirect_to @usuario
else
render 'edit'
end
end
def destroy
@usuario = Usuario.find(params[:id])
@usuario.destroy
redirect_to usuarios_path
end
private
def usuario_params
params.require(:usuario).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,
:direction, :municipal, :zipcode, :tel1, :tel2)
end
end
这是我的Ficha控制器：
class FichasController < ApplicationController
before_action :authenticate_user!
def index
end
def show
@ficha = Ficha.find(params[:id])
end
def new
@usuario = Usuario.find(params[:usuario_id])
if @usuario.ficha.nil?
@ficha = @usuario.build_ficha
else
flash[:error] = "Ya tienes una ficha"
end
end
def create
@usuario = Usuario.find(params[:usuario_id])
@ficha = @usuario.build_ficha(ficha_params)
if @ficha.save
redirect_to @usuario, :notice => "Your ficha has been successfully created."
else
render :action => 'new'
end
end
def edit
#@ficha = Ficha.find(params[:id])
end
def update
@ficha = Ficha.find(params[:id])
if @ficha.update(ficha_params)
redirect_to @ficha
else
render 'edit'
end
end
def destroy
@usuario = Usuario.find(params[:usuario])
@ficha = @usuario.fichas.find(params[:id])
@ficha.destroy
redirect_to fichas_path
end
private
def ficha_params
params.require(:ficha).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,
:direction, :municipal, :zipcode, :tel1, :tel2, :time, :redes, :estudios, :profession,
:laboral, :discapacity, :percent, :derivado1, :derivado2, :derivacion, :nombredelprofesional,
:observaciones, :conocio, :signature, :date, :term)
end
end
我在控制器中创建ficha的某个地方出错了吗？在usuario模型中使用after_create后立即创建对象会更好吗？
任何帮助表示赞赏！谢谢！

对象无法保存，则可能是因为验证错误或未正确关联。
查看debugging with the console命令，了解如何解决这些类型的问题，方法是在保存尝试后插入@ficha以查看console对象是否附加了任何错误

在Rails 4.2.1中
我在这里看不到你使用了＃accepted; accepts_nested_attributes_for＆＃39;。阅读http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html
试试这些
class Ficha < ApplicationRecord
belongs_to :user
belongs_to :usuario
end
class Usuario < ApplicationRecord
belongs_to :user
has_one :ficha, :dependent => :destroy
accepts_nested_attributes_for :ficha
end
你也可以在UsuariosController中使用ficha_attributs，就像这些
一样private
def usuario_params
params.require(:usuario).permit(:name, :age, :doc, :docnum, :estadocivil, :country, :street,:direction, :municipal, :zipcode, :tel1, :tel2, ficha_attributes: [# Write ficha attributes you want save])
end
