The best way to use full-text search in django-filters' FilterSet?












0















My app uses rest-framework and django-filter. I use this FilterSet to provide filtering list of articles (ModelViewSet) by date:



from django_filters import rest_framework as filters



class ArticleFilter(filters.FilterSet):

    start_date = filters.DateTimeFilter(field_name='pub_date', lookup_expr='gte')

    end_date = filters.DateTimeFilter(field_name='pub_date', lookup_expr='lte') 



    class Meta:

        model = Article

        fields = ['pub_date']


I want to add search box to my app, so I need another filter, that will use full-text search at my Article model. Fields I would to search are title and description. I decided to add search field with method parameter like that:



from django_filters import rest_framework as filters

from django.contrib.postgres.search import SearchVector



class ArticleFilter(filters.FilterSet):

    start_date = filters.DateTimeFilter(field_name='pub_date', lookup_expr='gte')

    end_date = filters.DateTimeFilter(field_name='pub_date', lookup_expr='lte')

    search = filters.CharFilter(method='filter_search')



    def filter_search(self, queryset, name, value):

        return queryset.annotate(search=SearchVector('title', 'description')).filter(search=value)



    class Meta:

        model = Article

        fields = ['pub_date']


It works, but I'm not sure that it's the best way of using full-text search filtering. Am I missing something or this approach is ok?

          This is ok for a naive text search where you don't have much text to look into in a small-ish database.



          When you get into bigger areas you need to either optimize your db for this or move to a dedicated search engine like Solr or ElasticSearch. Postgres has a section on full text searching, as does mysql.

                    A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

                    0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
