ruby-on-rails - Default disable_with for simple_form submit

Question

I want to change the default behavior of my submit button in simple_form so that I needn't explicitly specify :disable_with => true for all my forms. How can I make this particular change in the simple_form.rb?

Answer 1

这在较新版本的 Rails 中略有不同，因为不推荐设置属性 disable_with。我为此写了一篇文章：http ://www.railsonmaui.com/blog/2014/02/23/simple-form-and-disable-processing-by-default/

这是新代码：

SimpleForm::FormBuilder.class_eval do
  def submit_with_override(field, options = {})
    data_disable_with = { disable_with: 'Processing...' }
    options[:data] = data_disable_with.merge(options[:data] || {})
    submit_without_override(field, options)
  end
  alias_method_chain :submit, :override
end

感谢@Appster 的想法！

将此覆盖添加到我的 simple_form.rb 就像一个魅力！

SimpleForm::FormBuilder.class_eval do
  def submit_with_override(field, options = {})
    submit_without_override(field, {:disable_with => 'saving...'}.merge(options))
  end
  alias_method_chain :submit, :override
end

Answer 3

根据ActionView::Helpers::FormBuilder.submit，f.button接受 1~2 个参数，因此以下两个代码都应该工作。

• f.submit "MyText", class: "my-btn"
• f.submit class: "my-btn"

就我而言，添加此代码来初始化文件工作正常。

SimpleForm::FormBuilder.class_eval do
  def submit_with_override(value=nil, options={})
    value, options = nil, value if value.is_a?(Hash)
    data_disable_with = { disable_with: 'Processing...' }
    options[:data] = data_disable_with.merge(options[:data] || {})
    submit_without_override(value, options)
  end
  alias_method_chain :submit, :override
end

希望能帮助到你。

Answer 4

它没有覆盖与 Rails 5 兼容的提交按钮上的任何现有数据属性。

module DisableDoubleClickOnSimpleForms
  def submit(field, options = {})
    if field.is_a?(Hash)
      field[:data] ||= {}
      field[:data][:disable_with] ||= field[:value] || 'Processing...'
    else
      options[:data] ||= {}
      options[:data][:disable_with] ||= options[:value] || 'Processing...'
    end
    super(field, options)
  end
end

SimpleForm::FormBuilder.prepend(DisableDoubleClickOnSimpleForms)
