ruby-on-rails - rails 4 : Why does this code not save Contact and Company to database?

Question

我目前被困在一个可能很简单的问题上，但不知何故让我有点困惑。

为什么在这个 Controller 方法中联系人和公司没有保存到我的数据库中？我在另一个 Rails 5 项目中调用了这个非常相同的方法，并且@company = Company.new(company_params) 似乎工作得很好。

def create
   @company = Company.new(company_params)
   @contact = Contact.new(contact_params) 

 respond_to do |format|
  if @company.valid? && @contact.valid?

    # SuggestionMailer.newcompany_email(@company, @contact.email, @contact.name).deliver_now

    format.html { redirect_to @company, notice: 'Company was successfully submitted.' }
    format.json { render :show, status: :created, location: @company }
  else
    format.html { render :new }
    format.json { render json: @company.errors, status: :unprocessable_entity }
  end
 end
end

这些是引用的方法:

def company_params
  params.require(:company).permit(:name, :location, :founded_date,  :category, :sub_category,
                                  :business_model, :target_client, :description, :main_url, 
                                  :twitter_url, :angellist_url, :crunchbase_url, :employee_count, 
                                  :all_tags, :category_id, :sub_category_id, :target_client_id, 
                                  :business_model_id)
end

def contact_params
  params.require(:contact).permit(:name, :email)
end

如果您能在这里提供简短的反馈，我将不胜感激。谢谢!

你好像忘了保存你的@contact和@compnay对象。

def create
   @company = Company.new(company_params)
   @contact = Contact.new(contact_params) 

 respond_to do |format|
  if @company.valid? && @contact.valid?
    # Save your Object here like
    @company = @company.save 
    @contact = @contact.save

    # SuggestionMailer.newcompany_email(@company, @contact.email, @contact.name).deliver_now

    format.html { redirect_to @company, notice: 'Company was successfully submitted.' }
    format.json { render :show, status: :created, location: @company }
  else
    format.html { render :new }
    format.json { render json: @company.errors, status: :unprocessable_entity }
  end
 end
end
