If you want clien-side, then you need to make some script-fu using jquery
or anything like that.

Re: Django Search Between 2 Dates

[Thiago Luiz Parolin]

I will try to explain, although I am not a good teacher.

Suppose you have an 'Example' model that has a 'data' field with
'auto_now_add = True'
And a function 'yesterday()' that returns yesterday, and 'past()' that
returns 'yesterday() minus some days'.

if you want to filter items between yesterday() and past(), you could
use something like:
Example.objects.filter(data__gte=past(),data__lte=yesterday())

 or using .exclude too

If you need more info, you can get better in django docs:
https://docs.djangoproject.com/en/3.1/ref/models/querysets/

I hope I helped a little despite my bad English.

Re: Django Search Between 2 Dates

[Steven Mapes]

Are you looking at client-side filtering within datatables or server side 
filtering? Thiago's suggestion related to using filters when you fetch the 
queryset 
(https://docs.djangoproject.com/en/3.1/topics/db/queries/#retrieving-specific-objects-with-filters)

django search page not found error

[omid jahadi]

Hello everybody! I want to search in a ManyToManyField in the DetailView. 
It works fine if a user with the same query exist, but if there isn't a 
user, i get page not found error.

agent_type = models.ForeignKey(types, on_delete=models.SET_NULL, 
blank=True, null=True)
name = models.CharField(max_length=100)
users = models.ManyToManyField(user_models.users, through='user_agent')

views.py:

class AgentDetailView(LoginRequiredMixin, generic.DetailView):
model = models.agents
template_name = 'agent/agent_detail.html'

def get_queryset(self):
query = self.request.GET.get('q')
if query:
return 
models.agents.objects.filter(Q(users__user__first_name__contains=query)
| 
Q(users__user__last_name__contains=query)
| 
Q(users__id_number__contains=query)
| 
Q(users__mobile__contains=query))
else:
return models.agents.objects.all()

agent_detail.html:

name: {{ agents.name }}


Search

{% if agents.users %}
Users:

Re: how do I make django search for male or female without needing to specify an age?

[Andy]

Why do you make a POST request for displaying a list? Use GET parameters 
like its done for admin filters.
And for building an API that returns JSON Data use DjangoRestFramework and 
you will just need to define your serializer fields .. the rest is taken 
care of for you. That code above looks overly complicated!

For instance you define app_name, model_name, method_name in 
filterchain_all although its not used.
Your are sending male and female intstead of the values itself as a normal 
django form would have done it.
Dont make a list out of the qs for no reason.
And instead of doing this "if int(item.age) not in [d['display'] for d in 
final]" over and over again use a set() to not get multiple results.

BUT moreover to get all distinct ages use:
Child.objects.vales_list('age', flat=True).order_by('age')
Done in one single line by your database instead of the handwritten view!

Please have a look at the django tutorial 
(https://docs.djangoproject.com/en/2.0/intro/tutorial01/) and keep an eye 
out for how the admin filters things in a way that can be linked from the 
outside with GET parameters (you cannot linkt to a filtered list that is 
requested by a post request)

Please stop using Q() in cases where its not neccessary .. all parameters 
in a queryset do mean AND. You only need a Q for more complex stuff or an 
actual OR.
Use a class based FormView to erase even more of the handwritten code and 
secure it with the LoginRequiredMixin.
Please dont ever again use a TemplateView for dynamic content use the 
render() method like shown in the tutorial!

Once you have completed the tutorial and embraced the concepts your code 
will be about 1/10 of the above and it will save you a lot of time figuring 
out how to do things that are already taken care of by Django if only you 
knew how. :)

Re: how do I make django search for male or female without needing to specify an age?

[Julio Biason]

Hi Eileen,

Your problem seems to be the line

  if form.is_valid() and form.data['gender'] != '-':

It seems it will only accept the form if the gender is not "-"; if you
change that (say, removing the part after the and), it should solve it.

... although you should have a better understanding of what your
application does to know if that will work or not.

how do I make django search for male or female without needing to specify an age?

[eileen]

I have a file: views.py which refers to two main fields on the page: age 
and gender
Right now, the search requires that an age to be chosen whether or not the 
gender is, and I'd like to make the age optional as well. I.e get all the 
children.
Additionally, I'd like to search for only males or females without 
selecting an age...

Re: Django search

[Luis Zárate]

This could be usefull


Model.objects. filter(q='hello', b='world')

Can be expressed as

params ={'q': 'hello', 'b': 'world')
Model.objects.filter (**params)

Yes that is true, and I have succeeded in making select menu and checkbox

Re: Django search

[Fred Stluka]

  
  
Branko,

You may need to explain a little more.

It sounds like you have search working when you type the search 
string into a HTML text box.  True?

What do you want to do with the menu and checkbox?  Are you 
trying to arrange for the text of the menu label and the text of the
checkbox label to be combined somehow to form the search 
string?

django Search page

[Sabeen Sha]

 

 which is the best way to implement the following::
i will be having a text box and a Add button

Along with a table below it containing headers class 
AssesmentBuildingDetails(models.Model): 


 numbuildingid1 = models.CharField(max_length=14,unique=True) 

numbuildingid2 = models.CharField(max_length=7,primary_key=True) 

previous_year = models.CharField(max_length=4, blank=True) 

previous_year_wardname = models.CharField(max_length=100,blank=True, 
null=True) 

previous_doorno1 = models.CharField(max_length=4,blank=True, null=True) 

previous_doorno2 = models.CharField(max_length=10,blank=True, null=True) 

current_year = models.CharField(max_length=4, blank=True) 

current_year_wardname = models.CharField(max_length=100,blank=True, 
null=True) 

current_doorno1 = models.CharField(max_length=10,blank=True, null=True) 

current_doorno2 = models.CharField(max_length=10,blank=True, null=True) 

buildingusage = models.CharField(max_length=500,blank=True, null=True) 

ownernameaddressmal = models.CharField(max_length=500,blank=True,

null=True) 

plintaarea = models.DecimalField(max_digits=7, decimal_places=2,blank=True, 
null=True) 

class Meta: 

db_table = 'assesment_building_details' 


 
my logic is to take the numbuildingid2 as input from the text box and when 
i press enter either on the text field or click the add button it should 
search through the database
and add the details to the table without refreshing the whole page. and the 
clear the textfield and focus on it.
 It will give proper error msg if the numbuildingid2 is not found

please help how and which is the best way to implement this... 

thanks

Ok I did what you said and played around for a while and got it working! 
Thanks! Another issue I had which I think was the main one (as well as the 
namespace in my input) was that I needed to change my action to link to a 
url which validated my search view. I ended up just using 
/beacon/search/search_query/ but anything instead of search_query would 
have worked. This way Django runs through the search view no matter what 
page you are on. Ironically changing that also implemented my search

I have tried hacking your code on top of one of my search pages, and
definitively managed to get it working once I added the name for the
input.

Without the name, the search view would otherwise just fall through and
I'd get something in the lines of the following error:

The view project.views.search didn't return an HttpResponse object.

I'd suggest maybe putting in a couple of debug print messages in your
view to figure out where your code ends-up in the end.

 Thanks for the response. I tried putting a name into the text input field 
but nothing changes- I am still redirected to /project/search/ and not 
/project/search//   . I have also tried to just use the default 
Django form link template tag with {{ form.search_string }} with the same 
result, which leads me to think that the issue has to do with maybe the 
submit button? I'm not sure, though...

I agree that POST is probably the less 'correct' thing to do here, the 
perfect example for using GET is ironically (in the Django docs themselves) 
a search bar. That said, I get so confused and frustrated when I have to 
use forms that I want to have a working prototype before I change it as 
most of the form tutorials out there use POST because they change models or 
something.

Seriously thanks for the response!

In your search method, if the request method was POST, you are trying
to retrieve submitted data via key 'search_string'. However, if you
look at your HTML form, there does not seem to be any kind of input
field called 'search_string'.

Try adding name="search_string" parameter to the input element, for
example:



On a side-note, why are you even using POST method for a search? I
_think_ that GET should be sufficient, and probably more correct thing
to use, unless your searches are actually altering data (which could be
considered a bad practice).

Django Search via Form Redirect to URL

[Conner DiPaolo]

I already have a valid search function mapped in my Django project, you 
type in a url '/project/search//' and it responds the corresponding search 
results on a page. I want to have a search box in my nav-bar that was 
created in my base.html and have users type in a query and it will redirect 
them to the search url. When I type into the search bar and click submit, 
however, the I am just directed to '/project/search/' with no relation to 
the query. How do I connect the form to redirect to the URL, *properly*??

Thanks in advance.

Here is my view definition and form class:

class SearchForm(forms.Form):
search_string = forms.CharField(max_length=100)def search(request, 
search_query):
if request.method == 'GET':
form = SearchForm()
context = RequestContext(request)
search_string = search_query.replace('_',' ')
search_terms = search_query.split('_')
search_results = Article.objects.all()
for term in search_terms:
search_results = search_results.filter(article__icontains=term)

context_dict = {
'search_string':search_string,
'search_results':search_results,
'form':form,
}


if request.method == 'POST':
form = SearchForm(request.POST)
if form.is_valid():
search_string = form.data['search_string']
search_query = search_string.replace(' ','_')
###return HttpResponseRedirect(reverse('search', 
args=(search_query,)))
search_url = '/beacon/search/' + search_query + '/'
return HttpResponseRedirect(search_url)
else:
return render_to_response('search.html', context_dict, context)

My base form html is (yes it is from bootstrap):

You should be able to do it with the django .extra() method easy enough.  I 
believe you can also make a soundex index on columns to improve the 
performance.  

The python jellyfish library is nice for pre-calculating phonetic strings 
and storing them in the database to compare against, or for small data sets 
that you want to process in python.

A third option is something like 
https://github.com/niwibe/djorm-ext-pgfulltext  which uses postgres full 
text search.  The full text search uses tokens that are normalized.  I'm 
not sure it it would normalize amanjit to amanjeet with the default 
configuration, and may be overkill for what you want.

Is this search function a query like
MyModel.objects.filter(usernamename=username, ...) or something more
specific ?

Haystack is a full text search application, it build an index specific for
full text search which means it's not suited for the search you are looking
to do (also it takes a lot of memory).

It depends... can you write a query in the form of
MyModel.objects.filter(foo=bar, spam=egg) where you document each fields so
that we can know better what your are trying to achieve ? Real data is not
significant, but full scope of the problem you are trying to solve is.

I have a search function which is already working in views.py but I
want to refine it. How can I make a model without vowels??
And what is django-haystack application? Can I use it in my project
for fefinig search or is it a normal searching application?

You can do this by creating an extra field in the model with the name
without vowels in it and doing a simple filter on it ? Is that what you
need ?

This is really a question about regular expressions, not about Django. 
Whether you implement simple or complex search in Django, whether you use 
Django or some other platform, this is going to come down to using a fairly 
complex regular expression. So I would search for "regex ignore vowels" and 
similar. I would also expect performing a search like that to be extremely 
expensive, computationally, since it will need to tear apart every single 
word in the pool. That, in turn, means you'll want to use a search system 
with very robust indexes. In fact, you might do best with a system that

So, your trouble is that when you type in a number that is not found, 
Django shows you a not found error? And to prove that, you post a 
screenshot of the not found error, rather than posting any of the actual 
code, or describing what you would like to happen instead?

If you want to be helped, you have to help yourself.

Re: Implementing Django Search

[Daniel Sokolowski]

I also found that piece of code when I needed to implement search - it 
was confusing so I ended up with my own approach that was easier to 
understand and simpler at least to me - I pasted an example of live code 
here: http://dpaste.org/KYhUq/


The searching piece of code is in the form_valid() method:

query = (query.filter(name__icontains=bit) | 
query.filter(description__icontains=bit))


This filters the query down on each loop of the word user typed, you 
would adjust that according to your model fields.


Hope that helps.

The first action is to create a file within the project – say

def normalize_query(query_string,

>>> 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. Thanks.

Re: Implementing Django Search

[Nikolas Stevenson-Molnar]

There are a number of ways you can use it. Must straight-forward is to
use built-in views with a customized template:
http://django-haystack.readthedocs.org/en/latest/tutorial.html#setting-up-the-views

You can get a bit more advanced by using the various search forms with
your own view:
http://django-haystack.readthedocs.org/en/latest/views_and_forms.html

Or, you can use the basic components (SearchQuerySet) and do everything
else yourself:
http://django-haystack.readthedocs.org/en/latest/searchqueryset_api.html

Even the last case is pretty easy to use. Connecting it to a search form
is as easy as getting the query string from GET or POST data. E.g.:

def my_view(request):
results = SearchQuerySet().filter(content=AutoQuery(results.GET['q']))

Does it provide instructions on connecting it to a search form? Dumb 
question, but sometimes documentation can be lacking.

I've used Haystack with Whoosh: http://haystacksearch.org/. It's
straight-forward, well documented, and mimics the Django ORM. No need to
parse the query yourself or anything like that, just pass the raw input

Implementing Django Search

[DF]

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. Thanks.

Django Search Form in Admin

[Alessandro Ronchi]

Given a simple model, I need to write a search form in admin (not the
text search inside admin model list).

It's the same as a form.as_table() but inside admin.

Is it possible?

Any working example?

I also need to insert a button with a link to export the result
queryset to Excel or PDF. (a simple link pointing to a view sending
the search form filled as POST).

Must I write a new app outside the admin?

Re: ANNOUNCE: Django search with Lucene.

[Spike^ekipS]

Hi, Ben.

I already knew that project, djangosearch and at first my first
candidate to use lucene in django is also djangosearch :) but it is
under early stage of development and I need the one, which is /* more
integrated with django queryset */, not raw lucene query, so I
determined to write my own lucene search in django.

As you said, PyLucene has threading problems in some circumstance, but
with the latest PyLucene(with JCC), which is used in Django search
with Lucene I did not found any problems on Threading, but more
detailed and sophiscated testing will be needed.

Thanks.

Apparently PyLucene has problems with threading, which is why it is  
not a priority for djangosearch. Have you run into anything like that?

Re: ANNOUNCE: Django search with Lucene.

[Spike^ekipS]

I did not test with fcgi, I'm running 'django search with lucene' in
the Twisted Web2, but new pylucene(PyLucene with JCC) support the
attachCurrentThread(and detachCurrentThread) for Thread-SAFE and the
Django search with Lucene was tested in thread environment(index
writing and reading). I read this document,
http://svn.osafoundation.org/pylucene/trunk/jcc/jcc/README .

Thanks.

Pylucen in thread must
import PyLucene.PythonThread as thread。
have you test it for fcgi?

ANNOUNCE: Django search with Lucene.

[Spike^ekipS]

Hi, django users and developers.

I'm happy to let you know my django application, Django search with
Lucene(DSL). I try
to tighly integrate the Lucene with Django, so I find the way to use
lucene easily in Django.

Django search with Lucene(DSL) supports,
 * indexing object automatically when object is saved(update, delete
also applied in index)
 * search indexed document by django filtering expression
   >>> Person.objects_search.filter(name="spike", age=10)
 * indexing the existing object  like this,
   >>> Person.objects.filter(pk__gte=100).create_index()
 * etc.

Make a story short, this is examples,
===
person = Person.objects.create(
name_first="Spike",
name_last="Ekips",
)

person.name_first = "New Spike"
person.name_last = "New Ekips"
person.save()
>>> Person.objects.objects_search(name_first="Spike").exclude(name_last="ekips").order_by("-time_added")
>>> Person.objects_search(name_first__icontains="pike").order_by("-time_added")
>>> Person..objects_search(
time_added__lte=(datetime.datetime.now() -
datetime.timedelta(days=10))
)
>>> result = Person.objects_search(
time_added__lte=(datetime.datetime.now() -
datetime.timedelta(days=10))
)

>>> for i in result :
print i.get("name_first")
print i.name_first
print i.pk
print i.get("__uid__")
print i.get("name_last")
===
object automatically indexed when saved and analyzed and we can digg
the index db with django model filtering expression.

http://code.google.com/p/django-search-lucene/
or see the short document at 
http://django-search-lucene.googlecode.com/files/django-search-lucene.pdf

I would also be interested in any advice on this. Every time I
implement a search I seem to hit a dead end.

Django search engines

[Greg]

Does anyone have any experience using djangosearch, djapian, or django-
search?  Any tutorials for using any of them?  I'm kinda unsure as to
where to begin implementing any of them.

Simple Django search

[Maciej Bliziński]

Hi Djangoers!

I've been interested in a search feature in Django for some time now.
I did some research lately and found the following posts about it:

* Search Functionality http://tinyurl.com/28talc
* Search options http://tinyurl.com/2xuno3
* How to integrate a search engine in a Django site? http://tinyurl.com/ypor32
* Search feature http://tinyurl.com/yvv289

I've found that all of those solutions require some additional
software (such as Lucene, for instance). I was thinking about
something that would be pure Django/Python code, that would work like
django.contrib.comments.

I've recently written the simplest code I could, to do the job: index
objects and then allow to search them, returning their titles and
absolute URLs. I've tried to make it as general as possible. My
implementation is inspired (or stolen from ;-) )
django.contrib.comments. It can index any class of objects. Classes to
be indexed need to implement two methods: get_search_text() and
get_absolute_url()

Here's an example code for indexing objects:

from myapp.models import MyClass
from django.contrib.search.models import Keyword
from django.contrib.contenttypes.models import ContentType

ct = ContentType.objects.get_for_model(MyClass)
object_id = 1
Keyword.objects.index_object(ct, object_id)

...and for searching:

from django.contrib.search.models import KeywordManager
from django.contrib.contenttypes.models import ContentType
from myapp.models import MyClass
ct = ContentType.objects.get_for_model(MyClass)
km = KeywordManager()
result = km.search(ct, "Monty Python")
print result

[{'url': '/path/object/',
 'preview': 'preview of the object content',
 'title': 'Object title' },
 { ... }, ... ]

Results are a list of dictionaries where each dictionary has fields:
url, preview and title.

The code is available from:
http://code.blizinski.pl/django-search/

This is very immature code which I've put together last few days, but
it does the job and I think it could be useful for other people too.

It's biggest strength is that it's enough to put few files into the
django/contrib directory and run syncdb -- it's ready to go.

All comments are very welcome!

Maciej Bliziński
