Je crée un petit projet pour mes étudiants et je suis confronté à un message d'erreur J'ai essayé toutes les solutions possibles mais je n'ai pas progressé.

a>

Les images sont les différents modèles a et comment j'ai mis en place les associations respectives. Et aussi la méthode du contrôleur de Create et les paramètres autorisés.

Je peux clairement voir à partir de mes activités de serveur que toutes les valeurs d'attributs ont été capturées, mais je reçois une erreur indiquant "L'activité doit exister" .

Je serais heureux si quelqu'un aidez-moi.

Merci d'avance

Je tente toujours de résoudre le problème

J'ai essayé la plupart de vos suggestions mais je n'ai toujours pas progressé, mais quand j'ai essayé ce qui suit, comme indiqué dans le code ci-dessous, j'obtiens un résultat étrange et pourtant je ne peux pas être inséré dans la base de données

def new
    @user_activity = UserActivity.new
end

def create
    # @user_activity = UserActivity.new(user_activity_params)
    activity_id = user_activity_params[:activity_id] #fetch this value from params as it comes

    puts "The activity ID which is received is -> #{activity_id.to_i}"
    # puts current_user.user_id

    user_activity_date = user_activity_params[:user_activity_date]
    puts "Date -> #{user_activity_date}"

    user_activity_start = user_activity_params[:user_activity_start]
    puts "Start Time -> #{user_activity_start}"

    user_activity_end = user_activity_params[:user_activity_end]
    puts "End Time -> #{user_activity_end}"

    user_activity_note = user_activity_params[:user_activity_note]
    puts "Activity Note -> #{user_activity_note}"

    @user_activity = current_user.user_activities.new(activity_id:activity_id.to_i, user_activity_date: user_activity_date.to_date,user_activity_start: user_activity_start.to_time,user_activity_end: user_activity_end.to_time,                            user_activity_note: user_activity_note )
end
