如何使用改革预先填充特色对象？ [英] How to use Reform to prepopulate for featured objects?

问题描述

例如，当用户点击拍照时，我们如何使用专门为特色挑战设置的属性预填充create.html.erb表单，例如 12 天，然后做周二，周四？

我使用

  #challenges_controller 
 def创建
 @challenge = Challenge.new（challenge_params）#create用于GET，然后POST 
 if params [：step] =='2'
 @challenge = current_user.challenges.build（challenge_params）
 @ challenge.save 
 redirect_to @challenge 
 end 
 end 
 
 #challenge / create.html.erb 
 <％= simple_form_for（@challenge）do | f | ％GT; 
<％= hidden_​​field_tag：step，2％> 
挑战：<％= f.text_field：action％> 
 Do For：<％= f.number_field：days_challenged，value：10％> 
执行时间：<％= f.collection_check_boxes：committed％> 
<％end％> 
  

  class ChallengeForm< Reform :: Form 
 property：action 
 property：committed 
 property：days_challenged 
 
 model：challenge 
 
 def commited 
 super || action_to_commited_hash [model.action] 
结束
 
 def days_challenged 
 super || action_to_days_challenged_hash [model.action] 
 end 
 
 def action_to_days_challenged_hash 
 {
'Run a Mile'=> 30，
'拍照'=> 12 
} 
结束
 
 def action_to_commited_hash 
 {
'跑一英里'=> ['Mon'，'Wed'，'Fri']，
'拍照'=> ['Tue'，'Thu'] 
} 
结束
结束
  

因为现在 ChallengeForm 对create.html.erb没有任何影响。我们如何才能正确地将默认值插入到create.html.erb中，具体取决于：action ？

解决方案

试试这个：
$ b

challenges_controller

  def new 
 @form = ChallengeForm.new（Challenge.new）
 
 respond_modal_with @form，location：root_path 
 end 
 
 def创建
挑战= Challenge.new（challenge_params）
 @form = ChallengeForm.new（挑战）
 
如果params [：step] ==' 2'
 @form.validate（user_id：current_user.id）
 @form.save 
 redirect_to挑战
结束
结束
  

挑战/ new.html.erb

 <％= simple_form_for @form，html：{data：{modal：true}}，url：'your_challenge_create_path'，方法：：post do | f | ％GT; 
 
 <％= f.text_field：action，placeholder：'输入自定义挑战'％>< br> 
或选择特色挑战：
 <％= f.collection_radio_buttons：动作，[['跑一英里'，'跑一英里]，['喝16oz水'，'饮料16oz水''，'拍照'，'拍照']，['最大饮料1'，'最大饮料1']，['见艾菲尔铁塔'，'见艾菲尔铁塔']，['写书籍'，'写书']，['Skydive'，'Skydive']，['开办企业'，'创业']，['没有贪睡'，'没有贪睡'，''访问所有50个国家'，'访问所有50个国家']，['与陌生人交谈'，'与陌生人交谈']，['尝试新食谱'，'尝试新食谱']，['快速媒体'，'Media-fast']]，：first，：last％> 
<％= f.submit％> 
<％end％> 
  

挑战/ create.html.erb

 <％= simple_form_for @form，html：{data：{modal：true}}，url：'your_challenge_create_path'，方法：：post do | f | ％GT; 
<％= hidden_​​field_tag：step，2％> 
挑战：<％= f.text_field：action％> 
对于：<％= f.number_field：days_challenged％> 
执行时间：<％= f.collection_check_boxes：committed％> 
<％end％> 
  

我可能有点偏离，但您明白了吗？

When a user clicks, for example, "Take a Picture" how can we prepopulate the create.html.erb form with attributes specifically set for that featured challenge, like do for 12 days and do on Tue, Thu?

I am using the reform gem.

#challenges_controller
def new
  @challenge = Challenge.new
  respond_modal_with @challenge, location: root_path
end

#challenges/new.html.erb
<%= simple_form_for(@challenge, html: { data: { modal: true } })  do |f| %>
  <%= f.text_field :action, placeholder: 'Enter a Custom Challenge' %><br>
    Or choose a featured challenge:
  <%= f.collection_radio_buttons :action, [['Run a Mile','Run a Mile'], ['Drink 16oz of Water','Drink 16oz of Water'], ['Take a Picture','Take a Picture'], ['1 Drink Max','1 Drink Max'], ['See Eiffel Tower','See Eiffel Tower'], ['Write a Book','Write a Book'], ['Skydive','Skydive'], ['Start a Business','Start a Business'], ['No Snooze','No Snooze'], ['Visit All 50 States','Visit All 50 States'], ['Talk to a Stranger','Talk to a Stranger'], ['Try a New Recipe','Try a New Recipe'], ['Media-fast','Media-fast']], :first, :last %>
  <%= f.submit %>
<% end %>

#challenges_controller
def create
  @challenge = Challenge.new(challenge_params) #create is being used to GET and then POST
  if params[:step] == '2'
    @challenge = current_user.challenges.build(challenge_params)
    @challenge.save
    redirect_to @challenge
  end
end

#challenges/create.html.erb
<%= simple_form_for(@challenge)  do |f| %>
<%= hidden_field_tag :step, 2 %>
  Challenge: <%= f.text_field :action %>
  Do For: <%= f.number_field :days_challenged, value: 10 %>
  Do On: <%= f.collection_check_boxes :committed %>
<% end %>

class ChallengeForm < Reform::Form
  property :action
  property :committed
  property :days_challenged

  model :challenge

  def commited
    super || action_to_commited_hash[model.action]
  end

  def days_challenged
    super || action_to_days_challenged_hash[model.action]
  end

  def action_to_days_challenged_hash
    {
      'Run a Mile' => 30,
      'Take a Picture' => 12
    }
  end

  def action_to_commited_hash
    {
      'Run a Mile' => ['Mon', 'Wed', 'Fri'],
      'Take a Picture' => ['Tue', 'Thu']
    }
  end
end

As it is now ChallengeForm has had no effect on create.html.erb. How can we get it to properly insert the defaults into create.html.erb depending on the featured :action?

解决方案

Try this:

challenges_controller

  def new
    @form = ChallengeForm.new(Challenge.new)

    respond_modal_with @form, location: root_path
  end

  def create
    challenge = Challenge.new(challenge_params)
    @form = ChallengeForm.new(challenge)

    if params[:step] == '2'
      @form.validate(user_id: current_user.id)
      @form.save
      redirect_to challenge
    end
  end

challenges/new.html.erb

<%= simple_form_for @form, html: { data: { modal: true } }, url: 'your_challenge_create_path', method: :post do |f| %>

  <%= f.text_field :action, placeholder: 'Enter a Custom Challenge' %><br>
  Or choose a featured challenge:
  <%= f.collection_radio_buttons :action, [['Run a Mile','Run a Mile'], ['Drink 16oz of Water','Drink 16oz of Water'], ['Take a Picture','Take a Picture'], ['1 Drink Max','1 Drink Max'], ['See Eiffel Tower','See Eiffel Tower'], ['Write a Book','Write a Book'], ['Skydive','Skydive'], ['Start a Business','Start a Business'], ['No Snooze','No Snooze'], ['Visit All 50 States','Visit All 50 States'], ['Talk to a Stranger','Talk to a Stranger'], ['Try a New Recipe','Try a New Recipe'], ['Media-fast','Media-fast']], :first, :last %>
  <%= f.submit %>
<% end %>

challenges/create.html.erb

<%= simple_form_for @form, html: { data: { modal: true } }, url: 'your_challenge_create_path', method: :post do |f| %>
  <%= hidden_field_tag :step, 2 %>
  Challenge: <%= f.text_field :action %>
  Do For: <%= f.number_field :days_challenged %>
  Do On: <%= f.collection_check_boxes :committed %>
<% end %>

I might be a bit off, but you get the point?
