table 中的嵌套表单不起作用
Nested form in a table, not working
有人可以帮助我如何将嵌套表单放入 table 中吗?
我的代码:
#app/view/master_templates/edit.html.erb
<%= form_for(@master_template) do |f| %>
<%= f.label :name %><br />
<%= f.text_field :name %>
<table border="1">
<%= f.fields_for :master_template_details, :wrapper => false do |p| %>
<%= render 'master_template_detail_fields', {f: p} %>
<% end %>
<tr><td><%= link_to_add_fields "Add Details", f, :master_template_details %></td></tr>
</table>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
#app/views/master_templates/_master_template_details_fields.html.erb
<tr class="fieldset">
<td><%= f.hidden_field :id %></td>
<td><%= f.select :field_type_id, options_from_collection_for_select(FieldType.all, :id, :name, f.object.field_type_id) %></td>
<td><%= f.hidden_field :_destroy %></td>
<td><%= link_to "Remove Detail", '#', class: "remove_fields" %></td>
</tr>
#app/helpers/application_helper.rb.
def link_to_add_fields(name, f, association)
new_object = f.object.send(association).klass.new
id = new_object.object_id
fields = f.fields_for(association, new_object, child_index: id) do |builder|
render(association.to_s.singularize + "_fields", f: builder)
end
link_to(name, '#', class: "add_fields btn", data: {id: id, fields: fields.gsub("\n", "")})
end
#app/assets/application.js.coffee
jQuery ->
# Remove fieldset
$('form').on 'click', '.remove_fields', (event) ->
$(this).prev('input[type=hidden]').val('true')
$(this).closest('fieldset').hide()
event.preventDefault()
# Add more fieldset
$('form').on 'click', '.add_fields', (event) ->
time = new Date().getTime()
regexp = new RegExp($(this).data('id'), 'g')
$(this).before($(this).data('fields').replace(regexp, time))
event.preventDefault()
当我尝试单击 添加详细信息 link 时,它将在添加详细信息 link 的 <td>
中创建 <fieldset>*details*</fieldset>
. Remove Detail link 不工作,但没有 table 它工作。
我找到了 this,但它不起作用或者我做错了。我是嵌套、ROR 和 js 的菜鸟。请帮忙详细点。谢谢
尝试一下是否有效。我不太确定。
