Question

我想用rails 5和mongoid创建一个邀请系统。但是，当我想发送电子邮件时，我有这个错误：

Recipient can't be blank
something goes wrong
Recipient can't be blank
No template found for InvitesController#create, rendering head :no_content
Completed 204 No Content in 137ms

以下是代码：

invite.rb

class Invite
  include Mongoid::Document
  include Mongoid::Timestamps

  field :email, type: String
  field :token, type: String

  belongs_to :project
  belongs_to :sender_id, :class_name => 'User', inverse_of: :recipient_id
  belongs_to :recipient_id, :class_name => 'User', inverse_of: :sender_id

  before_create :generate_token

  def generate_token
    self.token = Digest::SHA1.hexdigest([self.project_id, Time.now, rand].join)
  end
end

project.rb

class Project
  include Mongoid::Document
  include Mongoid::Timestamps

  # Principle informations concerning project
  field :title, type: String
  field :description, type: String
  field :client, type: String
  field :deadline, type: String
  field :creator_id, type: String

  belongs_to :owner, :class_name => 'User', inverse_of: :members
  has_many :members, :class_name => 'User', inverse_of: :owner
  has_many :invites
end

user.rb

class User
  include Mongoid::Document
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise  :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  ## Database authenticatable
  field :email,              type: String, default: ""
  field :encrypted_password, type: String, default: ""

  ## Recoverable
  field :reset_password_token,   type: String
  field :reset_password_sent_at, type: Time

  ## Rememberable
  field :remember_created_at, type: Time

  ## Trackable
  field :sign_in_count,      type: Integer, default: 0
  field :current_sign_in_at, type: Time
  field :last_sign_in_at,    type: Time
  field :current_sign_in_ip, type: String
  field :last_sign_in_ip,    type: String

  has_many :projects, inverse_of: :projects
  has_many :invitations, :class_name => 'Invite', :foreign_key => 'recipient_id'
  has_many :sent_invites, :class_name => 'Invite', :foreign_key => 'sender_id'
end

在用户页面上发送邀请的表单：

<%= form_for @invite do |f| %>
            <%= f.text_field :project_id, :value => @project.id %>
            <%= f.label :email %>
            <%= f.email_field :email %>
            <%= f.submit 'Send' %>
        <% end %>

invites_controller.rb

class InvitesController < ApplicationController
    def new 
        @invite = Invite.new
    end

    def create 
        @invite = Invite.new(invite_params)
        @invite.sender_id = current_user.id
        if @invite.save
            InviteMailer.new_user_invite(@invite, new_user_registration_path(:invite_token => @invite.token)).deliver
            redirect_to user_path(current_user.id)
        else
            puts @invite.errors.full_messages
            puts "something goes wrong"
        end
        puts @invite.errors.full_messages
    end

    private
    def invite_params
        params.require(:invite).permit(:email, :token, :sender_id, :recipient_id, [:project_id])
    end 
end

我希望所有者能够邀请其他人，如果用户存在，则将邮件发送给现有用户，但如果没有，则发送链接以创建帐户并在项目中注册，

我忘记了什么？为什么我有这个错误？

谢谢！

在创建操作中，最后您需要呈现页面，否则您需要将用户重定向到另一个页面。例如，像这样更改代码：

def create 
        @invite = Invite.new(invite_params)
        @invite.sender_id = current_user.id
        if @invite.save
            InviteMailer.new_user_invite(@invite, new_user_registration_path(:invite_token => @invite.token)).deliver
            redirect_to user_path(current_user.id)
        else
            puts @invite.errors.full_messages
            puts "something goes wrong"
            redirect_to :back #OR render :new
        end

end

观察我是否重定向用户，如果保存对象失败（在＆＃39;其他＆＃39;块结束时）

如果你想要更好的代码，你应该有这样的东西：

def create  
    @invite = Invite.new(invite_params)
    @invite.sender_id = current_user.id
    respond_to do |format|
      if @invite.save
        format.html { redirect_to '/', notice: 'Invite was successfully created' }
        format.json { render :@invite.json }
      else
        format.html { render :new }
        format.json { render json: @invite.errors, status: :unprocessable_entity }
      end
    end
end

以上代码处理html和json请求

默认情况下，Rails中的控制器会自动呈现名称与方法名称对应的视图。 create方法中的HttpSecurity http = ... http.exceptionHandling().accessDeniedPage("/403");块没有响应，因此rails正在寻找要呈现的名为else的视图。将create放在该块中，以便重新呈现render :new视图。

Answer 3

更改您的创建方法，如下所示：

def create 
  @invite = Invite.new(invite_params)
  @invite.sender_id = current_user.id
  if @invite.save
    InviteMailer.new_user_invite(@invite, new_user_registration_path(:invite_token => @invite.token)).deliver
    redirect_to user_path(current_user.id)
  else
    puts @invite.errors.full_messages
    puts "something goes wrong"
    render :new
  end
end

Ruby on rails - 没有找到InvitesController #create的模板
