Ruby on Rails-Action Mailer 400錯誤請求

Question

當我嘗試使用Ruby on Rails 4.1和Action Mailer發送表單時出現以下錯誤：

Started POST "/contact_sponsors" for 127.0.0.1 at 2018-05-17 16:22:35 -0300
Processing by ContactSponsorsController#create as JS
  Parameters: {"utf8"=>"✓", "contact_sponsor"=>{"company_name"=>"godocu@mailinator.com", "company_cnpj"=>"dahok@mailinator.com", "company_cep"=>"watyhib@mailinator.com", "company_address"=>"dofimocah@mailinator.com", "company_number"=>"duki@mailinator.com", "company_existence"=>"mamopiwir@mailinator.net", "company_sponsor_type"=>"", "responsible_name"=>"qomukuf@mailinator.com", "responsible_email"=>"ryhohiqe@mailinator.net", "additional_infos"=>"Eum sit nesciunt occaecat facere delectus vel aut sint animi pariatur Ut ipsum officia ratione est enim est"}}
  HomeConfig Load (4.1ms)  SELECT  `home_configs`.* FROM `home_configs`   ORDER BY `home_configs`.`id` ASC LIMIT 1

   (0.4ms)  ROLLBACK
  Rendered text template (0.0ms)
Completed 400 Bad Request in 16ms (Views: 0.8ms | ActiveRecord: 4.8ms)

有人可以幫助我嗎？ 我試圖以多種方式來解決這個問題，但無濟於事。 這是我的控制器，郵件程序和模型：

class ContactSponsorsController < InheritedResources::Base
  def create
    @contact_sponsor = ContactSponsor.new
    if @contact_sponsor.save
      ContactSponsorMailer.delay_for(10.seconds, retry: true).create(@contact_sponsor)
      render nothing: true, status: 200
    else
      render nothing: true, status: 400
    end
  end
end

class ContactSponsorMailer < ActionMailer::Base
  default from: "Facens Lince <no-reply@facens.br>"

  def create(contact_sponsor)
    @contact_sponsor = contact_sponsor
    mail(to: "felipe.marcon@atua.ag", subject: "Contato Através do Site")
  end
end

class ContactSponsor < ActiveRecord::Base
  validates :company_cnpj, :company_address, :company_number, :company_size, :company_existence, :company_sponsor_type, :responsible_name, :responsible_email, presence: true
end

謝謝。

Answer 1

@contact_sponsor.save返回false因此返回400。如果返回@false，請檢查@contact_sponsor.errors.full_messages錯誤，或使用save! 引發異常（不推薦使用，僅用於調試），看看出了什么問題。

Answer 2

根據顯示的日志和共享的代碼片段，似乎屬性“ company_sponsor_type”似乎是空字符串，並且在模型中，您編寫了相同屬性的true，因此它正在回滾。

因此，要么刪除驗證，要么在company_sponsor_type密鑰中發送一些值。

Answer 3

看，在ContactSponsor您已經validate必須存在的那些數據，但尚未傳遞任何表示空的數據，這就是為什么

完成了400個錯誤的請求

為此，您需要創建一個用於strong parameters的私有方法，如下所示

class ContactSponsorsController < InheritedResources::Base
    def create
        @contact_sponsor = ContactSponsor.new(contact_sponsor_params)
        if @contact_sponsor.save
            ContactSponsorMailer.delay_for(10.seconds, retry: true).create(@contact_sponsor)
            render nothing: true, status: 200
        else
            render nothing: true, status: 400
        end
    end

    private

    def contact_sponsor_params
        params.require(:contact_sponsor).permit(:company_cnpj, :company_address, :company_number, :company_size, :company_existence, :company_sponsor_type, :responsible_name, :responsible_email)
    end
end

我認為它將起作用。
