Export Data from QuerySet as Excel File in Django

Let's say you have this function in your views.py:
def funtion_name(request): if request.method == "GET": get_id = request.user.id ... ... ... args = [] kwargs = { 'landproperty__sownerid__id': get_id, 'geom__distance_lte': (pnt, D(km=kmdistance)), 'narea__lte': getarea } mm = YourModelHere.objects.filter(*args, **kwargs).values_list('fielname1', 'fielname2', 'fielname3','fielname4') request.session[0] = mm return HttpResponse(json.dumps(list(m)), content_type='application/json')
In order to get or pass the QuerySet from this function, you need to store it in a session as shown above.

Here's how to create an excel file:

I like her a lot...

I like her a lot that I stop and just stare her smile like forever. What the F***! I always love cute people and those who smiles like an anti-inflammatory capsule. Women really are powerful  being! Like drugs, they can ease pain and worsen it. They're like a double-edge sword. :D

Too bad, I'm so pessimistic! But I think, just this time I'll be hopeful. hahaha
Like I always say, for a long time I don't like being close to a woman, like having a romantic closeness. Sounds gay! hahaha
It's a choice! I do date sometimes but I just thought that I don't need a girlfriend that time. Too many reasons, right? I guess all those reasons won't matter if your feeling towards that girl is greater than those reasons. It's all about their weight.

And the song for this babble,

Changing password in Django

Image
Add this to your urls.py:


url(r'^accounts/change-password/', 'django.contrib.auth.views.password_change', {'post_change_redirect' : '/accounts/password-changed/'}), url(r'^accounts/password-changed/', 'django.contrib.auth.views.password_change_done'),
Just edit the links above. Then in you templates folder, create new folder and name it  registration . . Then create this html file below:


password_change_form.html
{% extends "edit_profile.html" %} {% block head_title %}Change Password{% endblock %} {% block content %} <div class="jumbotron" style="width: 940px; margin: 80px auto; border-radius: 5px;"> <form method="post" action="."> {% if next %} <input type="hidden" name="next" value="{{ next }}" /> {% endif %} {{form.as_p}} <input type="submit" value="Change"…

Serializing Objects and Passing Multiple JSON Data in Django

Below is just an example, just replace the necessary Models and Queries:


def pins_info(request): if request.method == "GET": getpin = request.GET.get('pin', None) keyvals = OrderedDict([ ('taxdec', 'landproperty__ctaxdec'), ('brgy', 'ssectionid__sbrgyid__cbrgyname'), ('landarea', 'narea') ]) keyvals1 = OrderedDict([ ('mydescription', 'description') ]) m = ButuanMaps.objects.filter(clandpin=getpin).values_list(*keyvals.values()) reference = ButuanMaps.objects.get(clandpin=getpin).geom within = SoilType.objects.filter(geom__contains=reference).values_list(*keyvals1.values()) within1 = ErosionMap.objects.filter(geom__contains=reference).values_list(*keyvals1.values()) result = dict(zip(keyvals, zip(*m))) result1 = dict(zip(keyvals1, zip(*within))) result2 = dict(zip(keyvals1, zip(*within1))) data = json.dumps([result, result1, result2], cls=DjangoJSONEncoder) return …
