Hello! I have a little problem saving some data in database...
I have to models.....
class Lesson < ActiveRecord::Base
has_many :sublessons, :dependent => :destroy
accepts_nested_attributes_for :sublessons
end
and
class Sublesson < ActiveRecord::Base
belongs_to :lesson
validates :subblesson_name, presence: true
validates :sublesson_content ,presence: true
end
I generated a form for add another sublesson like this (i know isn't
best way but i don't find another way)
<div style="padding:13px">
<%= form_for @lesson do |f| %>
<%= f.label :lesson_name, "Lesson title" %></br>
<%= f.text_field :lesson_name, class: "form-control"
%></br>
<%= f.label :lesson_icon, "Choise icon" %>
<%= f.select "lesson_icon", options_for_select([
"ico03",
"ico04","ico05","ico06"
])%></br></br>
<div>
<%= f.fields_for :sublesson do |sublesson_a| %>
<%= sublesson_a.label :sublesson_name, "Subtitle 1"
%></br>
<%= sublesson_a.text_field :sublesson_name, class: "form-control"
%></br> <%= sublesson_a.label :sublesson_content,
"Content"
%></br>
<%=sublesson_a.text_area 'sublesson_content', rows: 3,
class:
'form-control'%></br>
<%= sublesson_a.label :sublesson_video_link, "Video
link"
%><br>
<%= sublesson_a.text_field :sublesson_video_link, class:
"form-control" %></br>
</div>
<%=(1..50).each do |i|%>
<div class="add_new_subtitle">
<%= sublesson_a.label :sublesson_name, "Subtitle 1"
%></br>
<%= sublesson_a.text_field :sublesson_name, class:
"form-control" %></br>
<%= sublesson_a.label :sublesson_content, "Content"
%></br>
<%=sublesson_a.text_area 'sublesson_content', rows: 3,
class:
'form-control'%></br>
<%= sublesson_a.label :sublesson_video_link, "Video link"
%><br>
<%= sublesson_a.text_field :sublesson_video_link, class:
"form-control" %></br>
</div>
<%end%>
<%end%>
<a href="javascript:;" style="float:right"
class="btn
btn-primary" id="addNewTag">Add Sublesson</a>
<%= f.submit "Submit", class: "btn btn-primary"
%>
<% end %>
</div>
This is my methods
def create
#render text: params.inspect
@lesson = Lesson.new(lesson_params)
if @lesson.save
flash[:notice] = "You have successfully add a lesson."
redirect_to lessons_new_lesson_url
else
flash[:notice] = "Failed."
#redirect_to pages_add_lesson_url
end
end
def new
@lesson=Lesson.new
@lesson.build_sublesson
end
private
def lesson_params
params.require(:lesson).permit(
:lesson_name, :lesson_icon, sublesson_attributes:[:sublesson_name,
:sublesson_content, :sublesson_video_link])
end
I want to save those data in database but i don't succeed. i try a lot
of ways....PLease tell me an option..Thanks(i'm running rails 4.1.1 and
ruby 2.0.0)
