我有一個表單來創建一個老師,並且在這個表單中有一個表格,我可以在其中註冊他們可以教授的主題以及一些相關的經驗。rails form從同一個實例發送很多行
但是我不知道該怎麼做,在模型中,在控制器和視圖中,因爲有添加嵌套字段到我的老師窗體,並在模型中使用nested_attributes,並允許它在控制器中。但我不知道該怎麼做..
型號
class Tutor < User
has_many :tutor_subjects
accepts_nested_attributes_for :tutor_subjects
end
在控制器I具備的功能...
def create
@tutor = Tutor.new(tutor_params)
@tutor.save
end
def tutor_params
params.require(:tutor).permit(:email,
:first_name,
:last_name,
:gender,
:password,
tutor_subjects_attributes: [])
end
end
和視圖
= simple_form_for [:admin, @tutor] do |f|
= f.error_notification
.col-md-8.col-sm-12
.form-inputs
= f.input :email
= f.input :password
= f.input :first_name
= f.input :last_name
= f.input :gender, collection: {Male: 1, Female: 2}, include_blank: "--Select gender--"
%h2.well.well-sm Subjects
%table.table
%thead
%tr
%th Subject
%th Experience
%th Options
%tbody#subjects
= f.simple_fields_for :tutor_subjects_attributes do |s|
%tr.subject0
%td
= s.input :subject_id, collection: Subject.all, label: false, include_blank: "--Select subject--", input_html: { id: "tutor_subjects_attributes_0_subject_id", name: 'tutor[tutor_subjects_attributes][0][subject_id]', class: "subject" }
%td
= s.input :experience, as: :text, label: false, input_html: { placeholder: "Type your experience", name: 'tutor[tutor_subjects_attributes][0][experience]', id: "tutor_subjects_attributes_0_experience" }
%td.options
= link_to :add_subject, "#", id: "add_subject", class: "btn btn-small btn-info"
所以有什麼問題?它與'tutor_subjects_attributes'強參數? – Aleksey
問題是,我想保存參數到嵌套模型,發送很多行,但不工作 – jacr1614
確實在我的答案下面? – Aleksey
