I\'m trying to make a search form for Django.
Its a typical search form and then returns a table of matches. I wish to paginate the tables returned.
The prob
The below works before and after a search form has been submitted:
Views.py
class PostListView(ListView):
model = Post #.objects.select_related().all()
template_name = 'erf24/home.html' # /_.html
context_object_name = 'posts' # default >> erf24/post_list.html
ordering = ['date_posted']
paginate_by = 3
def is_valid_queryparam(param):
return param != '' and param is not None
def invalid_queryparam(param):
return param == '' and param is None
class SearchView(ListView):
model = Post #.objects.select_related().all()
template_name = 'erf24/home.html' # /_.html
context_object_name = 'posts' # default >> erf24/post_list.html
ordering = ['date_posted']
paginate_by = 3
def get_queryset(self): # new
key = self.request.GET.get('key')
minp = self.request.GET.get('min')
maxp = self.request.GET.get('max')
if is_valid_queryparam(key):
obj = Post.objects.filter(Q(content__icontains=key) | Q(location__icontains=key)).distinct().order_by('date_posted')
if is_valid_queryparam(minp):
obj = Post.objects.filter(Q(price__gte=minp)).distinct().order_by('date_posted')
if is_valid_queryparam(maxp):
obj = Post.objects.filter(Q(price__lte=maxp)).distinct().order_by('date_posted')
if is_valid_queryparam(minp) & is_valid_queryparam(maxp):
obj = Post.objects.filter(Q(price__gte=minp) & Q(price__lte=maxp)).distinct().order_by('date_posted')
if is_valid_queryparam(key) & is_valid_queryparam(minp) & is_valid_queryparam(maxp):
obj = Post.objects.filter(Q(content__icontains=key) | Q(location__icontains=key)).distinct()
obj = obj.filter(Q(price__gte=minp) & Q(price__lte=maxp)).order_by('date_posted')
if invalid_queryparam(key) & invalid_queryparam(minp) & invalid_queryparam(maxp):
obj = Post.objects.all()
return obj
url.py
urlpatterns = [
path('', PostListView.as_view(), name='erf24-home'),
path('search/', SearchView.as_view(), name='erf24-search'),
]
Home.html
{% for post in posts %}
{{ post.price }}
{{ post.content }}
{{ post.location }}
{{ post.likes.count }}
{% if user in post.likes.all %} Unlike
{% else %} Like
{% endif %}
{% for image in post.image_set.all %}
{% endfor %}
{% endfor %}
{% if is_paginated %}
{% if page_obj.has_previous %}
First
Previous
{% endif %}
{% for num in page_obj.paginator.page_range %}
{% if page_obj.number == num %}
{{ num }}
{% elif num > page_obj.number|add:'-3' and num < page_obj.number|add:'3' %}
{{ num }}
{% endif %}
{% endfor %}
{% if page_obj.has_next %}
Next
Last
{% endif %}
{% endif %}
Worked like a charm :) Enjoy!
