我正在使用Cocoon作为嵌套表单,但是第一组字段不保存到数据库中,如果我创建第二行它们似乎保存得很好?
我猜它只是我忽视的东西
.*?
class Form < ActiveRecord::Base
has_many :questions
accepts_nested_attributes_for :questions, :reject_if => :all_blank, :allow_destroy => true
end
----- form_controller.rb
class Question < ActiveRecord::Base
belongs_to :form
end
def new
@form = Form.new
@form.questions.build
end
def create
@form = Form.new(form_params)
if @form.save
redirect_to action: "show", id: @form.id
else
render('new')
end
end
def form_params
params.require(:form).permit(:title, :description, :status, questions_attributes: [:form_id, :question_type, :question_text, :position, :answer_options, :validation_rules, :done, :_destroy])
end
---- _question_fields.html.erb
<%= simple_form_for Form.new ,:url => {:action => :create} do |f| %>
<div class="section-row">
<div class="section-cell">
<%= f.label :title, "Form Title" %>
<%= f.text_field :title, placeholder: "Form Title" %>

您在simple_fields_for中写了x = Struct.new(:att)
p x
--output:--
#<Class:0x007f8c3126c568>
你应该按照以下方式编写表格(如文件所示):
link_to_add_association

您忘记了f
前面的simple_fields_for
:simple_fields_for
不知道表单和关联,因此它会将发布到控制器的参数命名为不同的,因此它将被强大的参数定义阻止。
所以,如果你写
f.simple_fields_for :questions do |question|
它应该正常工作;)
较小的评论:
link_to_add_association
应该在循环之外,否则在没有循环的情况下它将不可见,并且将针对每个问题显示(在您的UI中可能有意义或可能没有意义)。id
的强参数中添加questions_attributes
(对编辑/删除很重要)
