I have a form like this…

<%= form_for @lesson do |f| %> <%= f.label :lesson_name, "Lesson title" %> <%= f.text_field :lesson_name, class: "form-control" %> <%= f.label :lesson_icon, "Choise icon" %> <%= f.select "lesson_icon", options_for_select([ "ico-03", "ico-04","ico-05","ico-06" ])%> 
    <div>
     <%= f.fields_for :sublessons do |sublesson_a| %>
     <div class="add_new_subtitle">
     <%= sublesson_a.label :sublesson_name, "Subtitle 1" %></br>
     <%= sublesson_a.text_field :sublesson_name, class:

“form-control” %>
<%= sublesson_a.label :sublesson_content, “Content” %>
<%=sublesson_a.text_area ‘sublesson_content’, rows: 3, class:
‘form-control’%>
<%= sublesson_a.label :sublesson_video_link, “Video link”
%>

<%= sublesson_a.text_field :sublesson_video_link, class:
“form-control” %>

<%end%> Add Sublesson <%= f.submit "Submit", class: "btn btn-primary" %> <% end %>

In controller i have…(because i want 51 sublessons fields)
def new_lesson
@lesson=Lesson.new
51.times{@lesson.sublessons.build}
end

The problem is in html the sublessons fields look like this…


Lesson title

Choise icon

This looks like an “invalid markup” issue. At the top of the section
you’ve
got:

<%= f.fields_for :sublessons do |sublesson_a| %>

but at the bottom you’ve got

</div>
<% end %>

So the first time around the loop, the second

there closes the
surrounding
(the one before f.fields_for). On subsequent
iterations,
the
is invalid (the next enclosing element is a tag, not a

) but most browsers will try to muddle through, causing weird rendering.

Are you trying to build a nested form? There’s a Railscast abut that,
and it’s also covered in the Rails Guides, I think. The thing is you
cannot nest a form inside another form – that’s just basic HTML rules,
nothing specific to Rails. To make a nested form, you need to declare it
as such in your view. I see that you have a relationship set up between
a lesson and a sub lesson, so you need to declare in that relationship
that the lesson accepts_nested_attributes_for the sub lessons. Then your
lesson form can contain sub lesson fields, and the whole thing will be
submitted and processed in one action.
