ruby-on-rails - 隐藏基于 bool 值的键值对

Question

我正在使用 Stripe 向我的用户收取辅导服务费用。目前，教练可以决定他想在他的设置中提供什么计划。

如果教练仅将 basic_coaching 设置为 false，那么这是唯一不应不出现的 Stripe 按钮。

我该怎么做？

这是我的架构:

t.boolean "basic_coaching", default: true
t.boolean "professional_coaching", default: true
t.boolean "premium_coaching", default: true
t.boolean "platinum_coaching", default: true

这是我的 Controller :

@usd_plans = { # Plan ID -> Description
  'basic_usd': 'Basic Coaching',
  'professional_usd': 'Professional Coaching',
  'premium_usd': 'Premium Coaching',
  'platinum_usd': 'Platinum Coaching'
}

这是我的看法:

- @usd_plans.each do |plan_id, description|
  td
    = form_tag(subscriptions_path) do
      = hidden_field_tag 'plan', plan_id
      = hidden_field_tag 'coach_id', @user.id
      = hidden_field_tag 'user_id', current_user.id
      = hidden_field_tag 'description', description
      - if current_user.coupon_code
        = hidden_field_tag 'coupon_code', current_user.coupon_code

      script.stripe-button(
        src='https://checkout.stripe.com/checkout.js'
        data-key=Rails.configuration.stripe[:publishable_key]
        data-name="#{@user.name}"
        data-description=description
        data-image="#{@user.avatar.url}"
        data-locale='auto'
        data-panel-label='Subscribe now'
        data-label='Buy'
        data-allow-remember-me='false'
        data-email=current_user.email
    )

这是所有 4 个 bool 值都设置为 true 时的样子。理想情况下，如果该特定 bool 值设置为 false，我会隐藏一个按钮。

您可以决定何时构建@usd_plans，例如像这样的东西:

@usd_plans = {}.tap do |plans| # Plan ID -> Description
  plans['basic_usd'] =  'Basic Coaching' if coach.basic_coaching?
  plans['professional_usd'] =  'Professional Coaching' if coach.professional_coaching?
  plans['premium_usd'] =  'Premium Coaching' if coach.premium_coaching?
  plans['platinum_usd'] =  'Platinum Coaching' if coach.platinum_coaching?
end

当然，您可以通过一些字符串连接和元编程让它变得更干。重复的版本更利于理解:)。

编辑:如果您想保留布局，请尝试将其隐藏在 View 中

@usd_plans = {}.tap do |plans| # Plan ID -> Description
  plans['basic_usd'] =  {name: 'Basic Coaching', visible: coach.basic_coaching? }
  # etc...
end

- @usd_plans.each do |plan_id, data|
  td
    next unless data[:visible]
    = form_tag(subscriptions_path) do
      = hidden_field_tag 'plan', data[:plan_id]
      = hidden_field_tag 'coach_id', @user.id
      = hidden_field_tag 'user_id', current_user.id
      = hidden_field_tag 'description', description
      - if current_user.coupon_code
        = hidden_field_tag 'coupon_code', current_user.coupon_code

      script.stripe-button(
        src='https://checkout.stripe.com/checkout.js'
        data-key=Rails.configuration.stripe[:publishable_key]
        data-name="#{@user.name}"
        data-description=description
        data-image="#{@user.avatar.url}"
        data-locale='auto'
        data-panel-label='Subscribe now'
        data-label='Buy'
        data-allow-remember-me='false'
        data-email=current_user.email
    )
