Re: Simple Search Feature

Hi,

"Is it safe"? Well that is your call to make. Depending number of songs it might not be meanful for enduser to see whole list which leads to things like pagination and restricting maximum number of returned entries.

thanks for the suggestions Ken. I just want to ask too if it's safe to display the list of songs even if the textbox is empty?

One of the issues is here:

        if request.method == 'GET':
            song_name = request.GET.get('name', "Error")
            songs = self.model.objects.filter(name__icontains=song_name)
        else:
            songs = self.models.all()
        return render(request, self.template_name, {'songs': songs})

When no parameter is passed, request.method is still "GET" - In fact, this method should only be called on a get method, making this test irrelevant.

You _could_ change it to look something like this:

        song_name = request.GET.get('name', None)
        if song_name:
            songs = self.model.objects.filter(name__icontains=song_name)
        else:
            songs = self.models.all()
        return render(request, self.template_name, {'songs': songs})

Hope this helps,

     Ken

Hi,

I am playing around on adding a search feature to a website. I am currently encountering a problem when the page should load a list of songs and after typing in a song title in the search box:

views.py

class SongListView(ListView):
    model = SongOne 
    context_object_name = 'songs'
    template_name = 'songs/song_list.html'

    def get(self, request, *args, **kwargs):

        if request.method == 'GET':
            song_name = request.GET.get('name', "Error")
            songs = self.model.objects.filter(name__icontains=song_name)
        else:
            songs = self.models.all()
        return render(request, self.template_name, {'songs': songs})

problem is when I click the search button with the text box empty, I am getting the list of all the song (url: /songs/?name=) but if I just load the page wihout clicking the submit button (url: /songs/), it doesn't give me the list all the songs. The search box works if I type the correct song name as it shows the song title.  Problem is the page should load all the songs before I search a particular song.

Any suggestions so I can enhance my code?

Thanks,

Jarvis
