无法使用SimpleForm为某些(文本，布尔值，...)类型创建自定义输入 [英] Can't create Custom inputs for some (Text, Booleans, ...) types, with SimpleForm

问题描述

我不知道为什么它不能正常工作-或-我缺少重要的东西吗?

I can't figure out why this is not working as it should - or - I'm missing something important ?

这是来自simple_form /lib/simple_form/form_builder.rb 的映射类型的列表:

Here's the list of the mapped types from simple_form / lib / simple_form / form_builder.rb:

map_type :text,                                :to => SimpleForm::Inputs::TextInput
map_type :file,                                :to => SimpleForm::Inputs::FileInput
map_type :string, :email, :search, :tel, :url, :to => SimpleForm::Inputs::StringInput
map_type :password,                            :to => SimpleForm::Inputs::PasswordInput
map_type :integer, :decimal, :float,           :to => SimpleForm::Inputs::NumericInput
map_type :range,                               :to => SimpleForm::Inputs::RangeInput
map_type :select, :radio, :check_boxes,        :to => SimpleForm::Inputs::CollectionInput
map_type :date, :time, :datetime,              :to => SimpleForm::Inputs::DateTimeInput
map_type :country, :time_zone,                 :to => SimpleForm::Inputs::PriorityInput
map_type :boolean,                             :to => SimpleForm::Inputs::BooleanInput

第一个问题，我可以将StringInput类扩展为:

---

First problem, I can extend StringInput class as:

#app/inputs/string_input.rb
class StringInput < SimpleForm::Inputs::StringInput
  def input
    if @builder.show?
      content_tag(:p, @builder.object[attribute_name], :class => :show)
    else
      super
    end
  end
end

(我已使用show?方法扩展了构建器以检测上下文:action =='show')

大多数时间都可以使用，但是:as =>不能使用:string 存在:

This is working most of the time but not when :as => :string is present :

<%= f.input :estimated_duration_rendered, 
  :as => :string,
  :label => mt(:estimated_duration), 
  :hint => mt(:estimated_duration_hint),
  :error => false,
  :required => false,
  :input_html => { :class => :digits_11, :placeholder => mt(:estimated_duration_placeholder), :value => format_duration(resource.estimated_duration, true) }
%>

第二个问题，我可以为StringInput，DateTimeInput，CollectionInput和BooleanInput创建自定义输入，但所有其他输入均不起作用.例如:

Second problem, I can create custom inputs for StringInput, DateTimeInput, CollectionInput and BooleanInput but all the others are not working. For example:

#app/inputs/text_input.rb
class TextInput < SimpleForm::Inputs::TextInput
  def input
    if @builder.show?
      "I will never show..."
    else
      super
    end
  end
end

即使我的表单中有此帮手，也是如此:

Even if I have this helper in my form:

<%= f.input :description, 
            :label => mt(:description), 
            :hint => mt(:description_hint, :max => MyModel::DESC_MAX_LENGTH), 
            :input_html => { :class => :large, :rows => 8, :cols => 1, :maxlength => MyModel::DESC_MAX_LENGTH, :placeholder => mt(:description_placeholder) }, 
            :error => false
%>

当然，描述具有文本数据类型.

我在做什么错了?

谢谢.

好，要使用此功能，您只需要 1.5.1 版本的SimpleForm.:-)

Well, to use this functionality you just need the 1.5.1 version of SimpleForm. :-)
