Devise 3 (rails 4) can't update user without password

Question

I\'m trying to update a user without having to provide a password, but approaches that worked on older devise/rails versions no longer work with devise 3 and rails 4 strong para

Answer 1

The key is in this "user_params[:password].blank?". The next is a example of the code:

def update
  if user_params[:password].blank?
    params = user_params_without_password
  else
    params = user_params
  end

  respond_to do |format|
    if @user.update(params)
      format.html { redirect_to @user, notice: t(:user_update) }
      format.json { render :show, status: :ok, location: @user }
    else
      format.html { render :edit }
      format.json { render json: @user.errors, status: :unprocessable_entity }
    end
  end
end

private

def set_user
  @user = User.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def user_params
  params.require(:user).permit(:email, :username, :first_name, :last_name, :admin, :locked, :password)
end

def user_params_without_password
  params.require(:user).permit(:email, :username, :first_name, :last_name, :admin, :locked)
end

Hope you help
