Question

Let’s say I need a simple search form:

<form action="<%= search_path %>" methode="GET">
  <input type="text" placeholder="where?" name="place_name" />
</form>

I need to generate a url based on the input field so I can show:

/search/some-value

I tried:

match 'search(/:place_name)', to: 'some_controller#some_action', as: 'search'

Any suggestions why it’s not working or what I’m doing wrong here?

Answer 1

If you submit a form, the parameters set via inputs within the form will be appended to the URL using query parameters — in your case that would look something like this:

/search?place_name=some-value

That’s the basic form behavior and there’s no easy way around this unless you want to use some Javascript to handle the request (which I would advice against in this case).

To use the default behavior however, your route would need to look like this:

match 'search', to: 'some_controller#some_action', as: 'search'

The parameter place_name will then be available in the controller using:

params[:place_name] 

Hope this helps.
