why update is occurred when i want to create a user with an existing mail (am using model validation validates :email, uniqueness: true)

Question

def create
    user = User.create(user_params)
    if user.save
      flash[:notice] = '#{params[:user][:role]} created successfully'
      redirect_to users_path(role: params[:role])
    else
      flash[:errors] = "#{user.errors.full_messages.join(', ')}"
      redirect_to new_user_path
    end
end

This is my create method in user controller and am using invitation gem file to send invitation.if I use same mail id to create another user then every data to existing user is updated. How can i prevent this from updating user.

can you please add your model code and error to the OP? – usmanali Dec 05 '16 at 06:20 — usmanali, Dec 05 '16 at 06:20

You should add unique email validation in your user model.

validates :email, uniqueness: true

Also, refactor your code like this:

def create
    user = User.new(user_params)
    if user.save
      flash[:notice] = '#{params[:user][:role]} created successfully'
      redirect_to users_path(role: params[:role])
    else
      flash[:errors] = "#{user.errors.full_messages.join(', ')}"
      redirect_to new_user_path
    end
end
