设备3（导轨4）无法在没有密码的情况下更新用户

Question

我正在尝试更新用户而不必提供密码，但是在旧设备/ rails版本上工作的方法不再适用于设计3和rails 4强参数。

我正在使用我的user_controller进行更新，但我也尝试使用自定义设计注册控制器和devise_parameter_sanitizer，但没有成功。

表单不需要密码（没有密码字段），处理更新的user_controller如下所示：

# PATCH/PUT /users/1
def update
  if user_params[:password].blank?
    Rails.logger.info "entered if statement"
    user_params.delete :password
    user_params.delete :password_confirmation
    Rails.logger.info(user_params.inspect)
  end
  @user = current_user
  if @user.update(user_params)
    redirect_to @user, notice: 'User was successfully updated.'
  else
    Rails.logger.info(@user.errors.inspect) 
    render action: 'edit'
  end
end

private

def user_params
  params.require(:user).permit(:screen_name, :full_name, :email, :about, 
    :location, :profile_pic, :password, :password_confirmation, :current_password)
end

..提交后的日志如下：

有谁知道为什么会出现密码错误？

Answer 1

密码验证来自用户模型：

validates :password, presence: true

解决方案是仅在更新时验证create和allow_blank上的状态：

validates :password, presence: true, length: {minimum: 5, maximum: 120}, on: :create
validates :password, length: {minimum: 5, maximum: 120}, on: :update, allow_blank: true

Answer 2

截至2014年，您可以简单地覆盖受保护的方法并执行：

class RegistrationsController < Devise::RegistrationsController

  protected

  def update_resource(resource, params)
    resource.update_without_password(params)
  end
end

Answer 3

您可以使用@user.update_without_password(user_params)方法更新其他字段。

例如，我在自定义的users_controller.rb中有这个。我用远程调用（ajax）更新。

#users_controller.rb

def update
  respond_to do |format|
    if needs_password?(@user, user_params)
      if @user.update_with_password(user_params_password_update)
        flash[:success] = 'User was successfully updated. Password was successfully updated'
        format.js {render 'update'}
      else
        error = true
      end
    else
      if @user.update_without_password(user_params)
        flash[:success] = 'User was successfully updated.'
        format.js {render 'update'}
      else
        error = true
      end
    end

    if error
      flash[:error] = @user.errors.full_messages.join(', ')
      format.js {render json: @user.errors.full_messages, status: :unprocessable_entity}
    end
  end
end

private

def needs_password?(user, user_params)
  !user_params[:password].blank?
end

def user_params
  params[:user].permit(:email, :password, :password_confirmation, :username, :full_name)
end

#Need :current_password for password update
def user_params_password_update
  params[:user].permit(:email, :password, :password_confirmation, :current_password, :username, :full_name)
end

Answer 4

关键在于“user_params [：密码] .blank？”。接下来是代码示例：

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

希望你能帮忙

Answer 5

我在这里玩了很多年。上面的mrstif所建议的答案都是有效的。如果您使用可验证模块Devise开箱即用（带有配置选项），您可以在不提供密码的情况下更新用户详细信息，因此非常小心滚动您自己的密码验证。

Answer 6

通过创建 app / controller / registrations_controller.rb

简单地覆盖Devise

class RegistrationsController < Devise::RegistrationsController

  protected
  def update_resource(resource, params)
    resource.update(params.except(:current_password))
  end
end

此代码将直接更新用户参数，但：current_password

并更新 config / routes.rb

devise_for :users, controllers: {registrations: 'registrations'}

Answer 7

我的目标是在不需要密码的情况下启用编辑用户属性，除非它正在更改电子邮件，密码或删除帐户。这对我有用：

应用程序/控制器/ registrations_controller.rb：

class RegistrationsController < Devise::RegistrationsController
  before_action :configure_permitted_parameters

  ...

  def update
    params[:user][:team_attributes][:id] = current_user.team.id
    account_update_params = devise_parameter_sanitizer.sanitize(:account_update)

    if password_required?
      successfully_updated = resource.update_with_password(account_update_params)
    else
      account_update_params.delete(:current_password)
      successfully_updated = resource.update_without_password(account_update_params)
    end

    if successfully_updated
      sign_in resource, bypass: true
      redirect_to '/'
    else
      render :edit
    end
  end

  def destroy
    current_password = devise_parameter_sanitizer.sanitize(:account_update)[:current_password]
    resource.errors.add(:current_password, current_password.blank? ? :blank : :invalid)
    error_messages = 'Current password ' + resource.errors[:current_password].join

    if resource.destroy_with_password(current_password)
      redirect_to '/'
    else
      redirect_to delete_account_path, notice: error_messages
    end
  end

  protected

  def configure_permitted_parameters
        devise_parameter_sanitizer.permit(:account_update) do |user_params|
      user_params.permit(:username, :email, :password, :password_confirmation, :current_password, :name, :phone_number
    end
  end

  private

  def password_required?
    (resource.email != params[:user][:email] if params[:user][:email].present?) || params[:user][:password].present?
  end
end

更新config / routes.rb：

devise_for :users, controllers: { registrations: 'registrations' }

在views / devise / registrations / edit.html.haml

中

# edit form
...
= simple_nested_form_for(resource, as: resource_name, url: registration_path(resource_name), html: { class: 'mo-form' }, defaults: { placeholder: false, hint: false }) do |f|
...

# delete form
...
= simple_form_for(resource, as: resource_name, url: user_registration_path(resource_name), method: :delete, html: { class: 'mo-form' }, defaults: { placeholder: false, hint: false }) do |f|
...
