(抱歉我的英文) 您好,我为我的错误创建了一个新帖子,以便更清楚地解释发生了什么 我添加了一个表“user-activities”,它允许我知道用户是否看到了某个活动 这是我的数据库的表示

#activities_controller.rb:9 => if @activity.save
控制器:
def create
@activity = Activity.new(activity_params)
@activity.user = current_user
if @activity.save
flash[:notice] = "Votre activité a été créée !"
redirect_to root_path
else
flash[:alert] = "Erreur lors la création"
redirect_to root_path
end
end
当我添加新表时,控制器没有改变,并且创建新活动的表单不包含错误(组ID /用户IS /内容/标题/日期等等...有效)
我的模特已经改变了:
BEFORE
活动模型:
class Activity < ApplicationRecord
belongs_to :user
belongs_to :group
validates :content, presence: true
end
用户模型:
class User < ApplicationRecord
rolify
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :user_groups
has_many :activities
end
之后:
活动模型:
class Activity < ApplicationRecord
has_many :user_activities, dependent: :destroy
has_many :users, through: :user_activities
belongs_to :user, class_name: 'User'
belongs_to :group
validates :content, presence: true
end
用户活动模型:
class UserActivity < ApplicationRecord
belongs_to :activity
belongs_to :user
end
用户模型:
class User < ApplicationRecord
rolify
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :user_groups
has_many :user_activities
has_many :activities, through: :user_activities
end
谢谢:)

在开发过程中,必须将@activity.save
替换为@activity.save!
,并获取有关错误的详细信息的异常。
