Active Admin內的ActiveModel :: ForbiddenAttributesError

Question

我有一個模型只能在活動管理員中創建。我有以下控制器設置：

def index 
@events = Event.all 
end 

def new 
@event = Event.new 
end 

def create 
@event = Event.new(event_params) 

末

private 

def event_params 
params.require(:event).permit(:venue, :trainer_id, :description, :training_request_id, :title, :date) 
end 
end 

我的事件模型：

class Event < ActiveRecord::Base 
has_one  :trainer, inverse_of: :events 
belongs_to :training_request, inverse_of: :event 

delegate :module, to: :training_request 
end 

所有領域都存在，但我不能明白爲什麼它拋出這個錯誤。

這裏是從錯誤的輸出：

Parameters: 

{"utf8"=>"✓", 
"authenticity_token"=>"H0sdhO3JsWBb8tYvFm52YvGsVvcnArigaVD+1r5HzL8=", 
"event"=>{"training_request_id"=>"3", 
"venue"=>"this is a venue", 
"description"=>"this is a descripton", 
"title"=>"event title", 
"date(1i)"=>"2018", 
"date(2i)"=>"3", 
"date(3i)"=>"5", 
"date(4i)"=>"05", 
"date(5i)"=>"00", 
"commit"=>"Create Event"} 

任何人有爲什麼發生這種情況的任何想法？

值得一提的是，在軌道控制檯內，它可以很好地保存。

controller do 
    def permitted_params 
    params.permit event: [:venue, :trainer_id, :description, :training_request_id, :title, :date] 
    end 
    end
