Job Search

Part of the Class-Based Views section of Coddy's Django journey. Lesson 18 of 18.

The last feature is a search box on the jobs page. A visitor types developer, presses Search, and sees only the jobs with that word in the title.

A search form uses GET, so the word lands in the URL as ?q=developer, where a link or a bookmark keeps it. The view reads it the way it reads ?city=, in get_queryset(). People type in any case, so match with a lookup that ignores it.

Filters chain: narrow by city when there is one, then by the word when there is one. The pagination links already use {% querystring %}, so a search survives the page change.

Challenge

Medium

Add a search to /jobs/:

A GET form at the top with a box named q and a Search button. The box keeps the searched word.
?q=developer lists the jobs whose title contains developer, in any case.
?q=engineer&city=Berlin lists the Berlin engineer jobs.

Press Run and search for developer.
