Ruby on rails 用于复杂关联的Rails嵌套表单
问题:Ruby on rails 用于复杂关联的Rails嵌套表单,ruby-on-rails,forms,associations,form-for,Ruby On Rails,Forms,Associations,Form For,问题: =rfv.text\u区域:值在编辑操作中呈现空文本区域(但在db中此字段有值) 无法获取参数中角色\字段\值[]的数组 我的模型和关联: class Participant < ActiveRecord::Base belongs_to :role has_many :role_field_values, dependent: :destroy accepts_nested_attributes_for :role_field_values end class
在编辑操作中呈现空文本区域(但在db中此字段有值)=rfv.text\u区域:值
- 无法获取参数中角色\字段\值[]的数组
class Participant < ActiveRecord::Base
belongs_to :role
has_many :role_field_values, dependent: :destroy
accepts_nested_attributes_for :role_field_values
end
class Role < ActiveRecord::Base
has_many :role_fields
has_one :participant
end
class RoleField < ActiveRecord::Base
belongs_to :role
has_many :role_field_values
end
class RoleFieldValue < ActiveRecord::Base
belongs_to :participant
belongs_to :role_field
end
使用f.fields\u for代替fields\u for=f.simple\u fields\u for:role\u field\u value for simple\u form gem
=simple_form_for [@project.becomes(Project), @participant] do |f|
=f.error_notification
h4 =@participant.profile.fio
.form-inline
=f.association :role, remote: true
=f.input :status
#role-fields
=fields_for :role_fields_values do |rfv|
-@participant.role.role_fields.each do |role_field|
.form-group
=rfv.hidden_field :role_field_id, value: role_field.id
br
=rfv.label role_field.name
=rfv.text_area :value, class: 'form-control'
.form-actions
= f.button :submit
