Re: Using Select2 autocomplete with Django project does not work while fetching the data

[Sajid Samsad]

Could you kindly suggest me some autocomplete library which I can use for 
my Django Project? My deadline is coming fast and furiously and I have 
already spent too much time on this autocomplete library `Select2`.

Re: Using Select2 autocomplete with Django project does not work while fetching the data

[Jason]

looks like something you should go to the select2 github issue tracker for, 
since this is not a django issue.  

In the meantime, try using the unminified version of select2, would be a 
more relevant stack trace for you to look through the errors without the 
transformed names.

But I didn't write the js. It is from select2.
And if the request is not hit then what should I write?
The request for the API is localhost:8000/api.alife-marine/search/products

Re: Using Select2 autocomplete with Django project does not work while fetching the data

[Jason]

That;s not quite what I mean 


See above, there's a XHR (ajax) request going to reddit and you can see the 
headers of the request/response as well as the data sent back.  What do you 
see of this when you call your search api?

Because it seems to me your request isn't being hit in the server from the 
client code

Re: Using Select2 autocomplete with Django project does not work while fetching the data

[Jason]

Couple questions:

Do you see the request going from the browser to the server and back?  Not 
using postman, but your browser dev tools network tab

you have just a `/` at your ajax url.  Shouldn't this be `//` for 
protocol-agnostic?

Re: Autocomplete in Django

[Melvyn Sopacua]

Then you need to learn Ajax.
You can't do dynamic forms like this and not use Ajax.

I linked django-autocomplete-light for a reason: if you follow the
docs and use it, you can build things you need without knowing Ajax.
However, if it doesn't work or is creating problems because of
incorrect input, it is vital you know the foundation of Ajax to
troubleshoot.

Re: Autocomplete in Django

[Melvyn Sopacua]

In particular, you need to override the ModelChoiceField that a
ModelForm creates automatically and replace it with a field that is
not based  on ChoiceField at all or skips it's validation method (like
https://github.com/yourlabs/django-autocomplete-light/blob/master/src/dal_select2/fields.py#L34).

Re: Autocomplete in Django

[Jani Tiainen]

Hi.

Besides the way Andréas described, there exist autocomplete fields that can
accept arbitrary input you can send to backend without having to create
special add phase.

Adding such functionality of course requires a custom field that can add
nonexisting values to database.

Re: Autocomplete in Django

[Andréas Kühne]

That really depends on how you want it to work?

I would probably add an item on the dropdown that shows the current items
in the database, with "Add city". If the user presses that you can have an
AJAX call that adds the item to the database.

AutoComplete With Django

[furqanmlk]

Hi there,

Sorry for posting this question even it had been answered but i tried
all my best to solve this issue,
if use result list in Jquery code directly it works.

Here is code,
HTML:

  
Type 
Something:

  
 

Jquery:
$(document).ready(function(){
$("#searchbox").autocomplete({

 source: '{% url AutoCompleteSearch %}',
 minLength: 2

});

});


View.py:

def AutoCompleteSearch(request):
#query = request.Get.get("q","")

Re: JQuery Autocomplete in Django Not Working

[Charleno Pires]

Use firebug to see if loading jquery. If not loading Jquery.
Try this in your terminal.

I'm using Ubuntu 8.04, but the path depends of your system operating.

export PYTHONPATH=/home/user/directory_of_your_project
export DJANGO_SETTINGS_MODULE=your_project.settings
django-admin.py runserver --adminmedia=/home/user/
directory_of_your_project/your_project/media/

This is incorrect.  Any querystring present in the request (?query=test for
this example) is not part of the url matching step.

What happens when you enter that url, exactly as reported from the 404 NOT
FOUND, in a browser address bar? Perhaps the detailed debug page of what
urls are being tried to match against what will give a clue as to why what
looks like it should be matching isn't.

The url for the view is r'^taglookup/$, meaning that the spacified url
should end with /$.In you case the complete url is:
taglookup/?query=test so, the regular expresion isn't corrert.

A quick fix should be to addd something like taglookup/.*

JQuery Autocomplete in Django Not Working

[Gath]

Guys,

I have the following code from some example i got from
here: 
http://lethain.com/entry/2007/dec/01/using-jquery-django-autocomplete-fields,

but its not working on my django application.

On my templete i have this function:

$(function(){ setAutoComplete("tags", "tagResults", "/taglookup/?
query="); });

and on my urls i have the following line

(r'^taglookup/$', 'twine.twineapp.views.tag_lookup'),

and my view looks like this:

def tag_lookup(request):
# Default return list
results = []
if request.method == "GET":
if request.GET.has_key(u'query'):
value = request.GET[u'query']
# Ignore queries shorter than length 3
if len(value) > 2:
#model_results = Book.objects.filter
(name__icontains=value)
TaggedItem = Tag.objects.get_by_model(Question,
Tag.objects.filter(name__in=[value]))
results = [ x.name for x in TaggedItem]
json = simplejson.dumps(results)
return HttpResponse(json, mimetype='application/json')

When i try to type anything on my "tags" field in the template,
firebug gives me the following error;

GET http://127.0.0.1:8000/taglookup/?query=test 404 NOT FOUND
JQuery-1.3.2.js (line 3633)

Any ideas where am goofing?

Gath
