I'm working on my first project and I'm attempting to implement a basic search function where users can search for a specific terms.
There are many options available, most a bit too heavy for what I require. I found this posting which illustrates how to implement a basic search function that sounds ideal: http://julienphalip.com/post/2825034077/adding-search-to-a-django-site-in-a-snap#disqus_thread The problem: the documentation is a bit incomplete, especially for a newbie. And I could use some help from those with experience on how to implement this. The first action is to create a file within the project – say search.py – with the following code: import re from django.db.models import Q def normalize_query(query_string, findterms=re.compile(r'"([^"]+)"|(\S+)').findall, normspace=re.compile(r'\s{2,}').sub): ''' Splits the query string in invidual keywords, getting rid of unecessary spaces and grouping quoted words together. Example: >>> normalize_query(' some random words "with quotes " and spaces') ['some', 'random', 'words', 'with quotes', 'and', 'spaces'] ''' return [normspace(' ', (t[0] or t[1]).strip()) for t in findterms(query_string)] def get_query(query_string, search_fields): ''' Returns a query, that is a combination of Q objects. That combination aims to search keywords within a model by testing the given search fields. ''' query = None # Query to search for every search term terms = normalize_query(query_string) for term in terms: or_query = None # Query to search for a given term in each field for field_name in search_fields: q = Q(**{"%s__icontains" % field_name: term}) if or_query is None: or_query = q else: or_query = or_query | q if query is None: query = or_query else: query = query & or_query return query Then the next step would be to import this file into the views – import search (not sure if the app name should proceed this). Then add this view, with the object detail changed to match my model: def search(request): query_string = '' found_entries = None if ('q' in request.GET) and request.GET['q'].strip(): query_string = request.GET['q'] entry_query = get_query(query_string, ['title', 'body',]) found_entries = Entry.objects.filter(entry_query).order_by('-pub_date') return render_to_response('search/search_results.html', { 'query_string': query_string, 'found_entries': found_entries }, context_instance=RequestContext(request)) After this, I'm a bit stumped. I assume this requires a basic url for the urls.py file, which seems straightforward enough. But I'm not sure how to place this within a template, what tags to use, etc. I have a search bar form on my main template page to which I would like to attach this. But returning the search/search_results.html template with the appropriate tags is a bit head scratching. This is a fairly long post but if anyone could provide some insight on implementing this search function, it would be much appreciated.
