如何在选定记录的轨道中为nested_attributes创建文本字段? [英] How to make text fields for nested_attributes in rails for selected records?
问题描述
我有三个模型报告,问题,答案
belong_to :question
问题
belong_to :reports
has_many :answers, :dependent => :destroy
accepts_nested_attributes_for :answers, :allow_destroy => true
报告
has_many :questions, :dependent => :destroy
accepts_nested_attributes_for :questions, :allow_destroy => true
在创建新报告时,会随机选择一些问题以这种方式将其添加到报告并显示表单:
While creating a new report some questions are randomly picked to be added to the report and show form in this way :
报告表格
<%= form_for @report do |f| %>
<div class="field">
<%= f.fields_for :questions do |builder| %>
<%= render "question_fields", :f => builder %>
<% end %>
</div>
<div class="actions">
<%= f.submit "Submit Report"%>
</div>
<% end %>
---部分问题字段---
<h4 class="question_name">
<%= f.object.name %>
</h4>
<%= f.fields_for :answers do |answer,index| %>
<%= render 'answer_fields', :f => answer %>
<% end %>
---部分答案字段--- <%= f.text_field:name,:placeholder =>在此处添加答案"%>
---Partial Answer_Fields--- <%= f.text_field :name, :placeholder => "Add your answer here" %>
但是,当我尝试编辑/创建新报告时,它将获取该特定问题的所有现有答案.而我想实现类似以下内容:
But when I try to edit/create a new report it fetches all the existing answers for that particular question. Whereas I want to implement something like :
---部分问题字段---
<h4 class="ques_title">
<%= f.object.name %>
</h4>
<% f.object.answers_for_report(@report).each do |answer| %>
<%= render 'answer_fields', :f => answer %>
<% end %>
---部分问题字段---
<b>What should be code here so that it again acts same as nested attributes and gets updated succesfully !!!</b>
问题模型
belong_to :reports
has_many :answers, :dependent => :destroy
accepts_nested_attributes_for :answers, :allow_destroy => true
def answers_for_report(@report)
self.answers.where("report_id = ? ",report.id)
end
推荐答案
这是我的问题的答案:
报告表格就像
<%= form_for @report do |f| %>
<div class="field">
<%= f.fields_for :questions do |builder| %>
<%= render "question_fields", :f => builder %>
<% end %>
</div>
<div class="actions">
<%= f.submit "Submit Report"%>
</div>
<% end %>
然后问题"question_fields"就像
Then Question 'question_fields' is like
<%= question.fields_for :answers, question.object. answers_for_report(@report) do |answer| %>
<%= render 'answer_fields', :f => answer %>
<% end %>
这仅传递答案的记录/记录集,并且仅呈现那些选定答案的字段.
This passes only a collections / set of records of answers and renders fields for those selected answers only.
