こんにちは、リモート レール フォームからいくつかのパラメーターを抽出しようとしています。問題のパラメーターは event_id です。
私のコントローラーでは、次のことを行いました。
def create
@availability = Availability.new(params[:availability])
@exclude = Availability.where(:event_id => params[:event_id]).select(:user_id).pluck(:user_id)
@players = User.where('team_id = ? and id NOT IN (?)', current_user[:team_id], @exclude).all
@event = Event.where('id = ?', params[:event_id])
respond_to do |format|
if @availability.save
format.html { redirect_to @availability, :notice => 'Availability was successfully created.' }
format.js { @availabilities = Availability.all }
else
format.html { render :action => "new" }
format.json { render :json => @availability.errors, :status => :unprocessable_entity }
end
end
end
そして、このリクエストを起動するアクションは次のとおりです。
%li= button_to 'Add', availabilities_path(:availability => {:team_id => @event.team_id, :user_id => user, :event_id => @event.id }), :remote => true, :method => :post, :class => 'button tiny success', :disable_with => 'Add'
問題は、モデルが event_id を検出しないのはなぜですか?
