Nest of inequity and despair

not realy

Today's instalment covers a few tricks I've encountered while working on Wami this last week:

Bootstrap autocomplete

Bootstrap has a JS plugin called typeahead, which is crap. Some guy tried to extend  it and his was crap also.

I used to use jQuery's autocomplete, but that was crap in Bootstrap. Until this guy re-styled it to work. That's the shit.

Simple_form

Absolutely rocks, use it! waaaay simple

Am I the only guy who thinks of 

when I read: 

plataformatec

...moving along...

Nested_form

Also very usefull, if only to get the link_to_add and link_to_remove helpers. You can read more here.

<%= f.fields_for :tasks do |task_form| %>
  <%= task_form.text_field :name %>
  <%= task_form.link_to_remove "Remove this task" %>
<% end %>
<%= f.link_to_add "Add a task", :tasks %>

Nested_form also works nicely inside simple_form: simple_nested_form_for

Fake it!

If like me you seem to be a corner-case magnet, then you have wondered how to use fields_for to render fields, but not the ones included in the model already. In my case, I wanted to add documents to a model, but not render a field set for any existing documents.

The answer ( in the context of the original documentation):

<%= f.fields_for :tasks, [] do |task_form| %>
  <%= task_form.text_field :name %>
  <%= task_form.link_to_remove "Remove this task" %>
<% end %>
<%= f.link_to_add "Add a task", :tasks %>

This will let you add child items, without cluttering the view with existing items
