De facto approach to sorting with will_paginate
I'm using the will_paginate gem to display a collection in a paginated fashion. Now I'd like to have sorting functionality on the columns of the list in the vi开发者_开发知识库ew. I've added my own custom mechanism for establishing this, but it left me wondering if there isn't a standard way of doing this, leveraging the simplicity and elegance of will_paginate.
Yes, There is an elegant way of doing it. Using ujs_sort_helper. You can find more details here
searchlogic plugs in nicely with will_paginate.
It doesn't sound like you're searching, but showing everything is just a special case for a search. You can use just the sorting features and ignore the rest if you don't wish to filter your data.
Java the Hutt's sortable_table
Go for broke. This is an AWESOME rails plugin. REALLY easy to set up.
On previous projects where I've implemented both sorting and paging, I've let will_paginate
handle the paging while using overwrite_params
to handle the sorting.
For example (assuming a table)
<tr>
<th><%= link_to "ID", overwrite_params(:sort => "id", :page => 1) %></th>
<th><%= link_to "Name", overwrite_params(:sort => "name", :page => 1) %></th>
</tr>
<tr>
... information ...
</tr>
overwrite_params
does exactly what you'd think it does... it will give you back the current url with any existing params overwritten with the values specified, or any previously non-existing values inserted into the url.
Since will_paginate
already preserves any url params, using overwrite_params
in your column headers along with resetting the page by to 1 (which is optional), means that you get to continue to use the benefits of will_paginate
without hacking it up to also handle your sorting.
