Question

What do I need to change in the code below to make it link to a view rendered as json?

<%= link_to 'JSON Link', @mymodel %>

So I’d like to generate the following url

http://localhost:3000/mymodels/1.json

instead of

http://localhost:3000/mymodels/1

(These urls both work as expected.)

Answer 1

To do this, you must specify the format:

<%= link_to 'JSON Link', your_model_path(@mymodel, :format => 'json') %>

The URL helper methods can be retrieved by running:

rake routes

The first column is the name of the helper method, on which you should append either _path or _url, the latter will generate an absolute URL.
