"Advanced" searches Rails's nested attributes functionality in order to
|
||
|
|
generate complex queries with nested AND/OR groupings, etc. This takes a bit
|
||
|
|
more work but can generate some pretty cool search interfaces that put a lot of
|
||
|
|
power in the hands of your users.
|
||
|
|
|
||
|
|
A notable drawback with these searches is
|
||
|
|
that the increased size of the parameter string will typically force you to use
|
||
|
|
the HTTP POST method instead of GET.
|
||
|
|
|
||
|
|
|
||
|
|
## Tweak your routes
|
||
|
|
|
||
|
|
```ruby
|
||
|
|
resources :people do
|
||
|
|
collection do
|
||
|
|
match 'search' => 'people#search', via: [:get, :post], as: :search
|
||
|
|
end
|
||
|
|
end
|
||
|
|
```
|
||
|
|
|
||
|
|
## Add a controller action
|
||
|
|
|
||
|
|
```ruby
|
||
|
|
def search
|
||
|
|
index
|
||
|
|
render :index
|
||
|
|
end
|
||
|
|
```
|
||
|
|
|
||
|
|
## Update your form
|
||
|
|
|
||
|
|
```erb
|
||
|
|
<%= search_form_for @q, url: search_people_path,
|
||
|
|
html: { method: :post } do |f| %>
|
||
|
|
```
|
||
|
|
|
||
|
|
Once you've done so, you can make use of the helpers in [Ransack::Helpers::FormBuilder](https://github.com/activerecord-hackery/ransack/lib/ransack/helpers/form_builder.rb) to
|
||
|
|
construct much more complex search forms, such as the one on the
|
||
|
|
[demo app](http://ransack-demo.herokuapp.com/users/advanced_search)
|
||
|
|
(source code [here](https://github.com/activerecord-hackery/ransack_demo)).
