Django checkboxes: pass value to another page (search -> search results)
I have a google-like searchbar on my homepage. index.html <form method="get" action="/search/" id="searchbarform"> <div id="searchbargroup" class="form-group"> <input id="homejs" type="text" class="form-control large input-medium search-query" name="q" placeholder='"Computer Science", "Web Analytics", "2INC0"'> <input type="submit" class="btn btn-default btn-main" id="searchbarbutton" value="Search!"> </div> <!-- form-group --> <label><input type="checkbox" name="checkbox" value="summariesbox" checked>Summaries</label> <label><input type="checkbox" name="checkbox" value="examsbox" checked>Exams</label> <label><input type="checkbox" name="checkbox" value="coursesbox" checked>Courses</label> <label><input type="checkbox" name="checkbox" value="majorsbox" checked>Majors</label> </form> The searches work fine, but I want to use the values of the checkboxes to limit the search results based on the values. The problem is that I cannot find a way to pass the values to the searchresultpage. Other people on stackoverflow used the values of the checkboxes on the same page. this is the view that gets called when you search something: views.py def search(request): if request.method == "POST": form = UserForm(request.POST) if form.is_valid(): new_user = User.objects.create_user(**form.cleaned_data) login(request, new_user) return redirect('index') else: form = UserForm() query = request.GET['q'] results = Resource.objects.filter(title__icontains=query) courses = Course.objects.filter(name__icontains=query) summaries = Resource.objects.filter(title__icontains=query) .filter(resourcetype = "Summary") exams = Resource.objects.filter(title__icontains=query) .filter(resourcetype = "Exam") return render(request, 'main/searchresults.html', {'courses': courses, 'summaries': summaries, 'results': results, 'exams': exams, 'query': query}) Other threads (Django check if checkbox is selected), write code in the view function that is associated with … -
Integration of django authentication system with Facebook API
I am integrating Django authentication and login system with Facebook Login API. The problem is that once Facebook username will be the same as existing in my project's database so the only solution to the problem is to catch Facebook username and add numbers or something to the string to make it unique ?

How to join tables in django
Please excuse me for this silly question, I'm a beginner and I can't find my way through documents. I have two models: class Student (models.Model): name = models.CharField(max_length=40) family = models.CharField(max_length=40) school = models.ForeignKey(School) class School (models.Model): name = models.CharField(max_length=40) rate = models.IntegerField(default=-1) I want to have a list of students which includes all data of school in it: [ { "name": "John", "family": "Doe" "school": { "name": "J.F.K", "rate": 1 } } ... ] How can I do this with django ORM? -

Updating MLab document in Python views but cannot find id
In my previous code, I am passing a geojson file directly. But this time, I modified the code that directly gets all objects from my Mlab DB through python models. models.py from mongoengine import * class Route(Document): type = StringField(required=True) route_id = StringField(required=True) geometry = LineStringField() properties = DictField() meta = {'collection':'routes'} views.py def index(request): features = [r._data for r in Route.objects.all()] geojson = {'type': 'FeatureCollection', 'features': features} return render(request, settings.TEMPLATES[0]['DIRS'][0] + '/load-map.html', { 'routes' : jsonpickle.encode(geojson) }) I'll be passing this to render in a Leaflet map thus the code above (jsonpickle.encode(geojson)) to make it a Geojson Feature Collection. I was expecting it to work the same way however, there seems to be a problem when it comes to obtaining the Object it... Instead of the usual code below to update a document: line = json.loads(request.body) _id = line['id'] try: Route.objects(id=ObjectId(_id.get('$oid'))).update(set__geometry=geometry, set__properties=properties) return HttpResponse("Success!") except: return HttpResponse("Error!") I couldn't get it to work because of the format that I found when printing out line trying to get the ObjectId: {u'py/object': u'mongoengine.base.datastructures.SpecificStrictDict', [... u'id': {u'py/object': u'bson.objectid.ObjectId', u'py/state': {u'py/b64': u'WC/JW7er55Q/GkhL\n'}}} How can I resolve this? -
Update javascripts that are cached in the Chrome browser
I have a Django + Guicorn + Nginx project. My problem is that every time after I had deployed a new change on EC2, the new change wouldn't get updated in the browser unless I deleted the cache locally. I don't really have a clue as of why this is the case and how I am supposed to implement my project to prevent this problem. -
MySQL: django.db.utils.OperationalError: (1366, "Incorrect integer value: 'Category object' for column 'category_id' at row 1")
Using MySQL with Django, I have changed a model from using strings for "category" to using a FK. It is now broken with django.db.utils.OperationalError: (1366, "Incorrect integer value: 'Category object' for column 'category_id' at row 1") Initially, it looked like: class ItemRecord(models.Model): catalog_id = models.IntegerField() name = models.CharField(max_length=250) price = models.DecimalField(max_digits=7, decimal_places=2) active = models.BooleanField(default=True) # is the item being sold at all?

Django REST Framework serializer with different models
I have three different models that I want to gather in a feed type page. They do all contain different types of things but for simplicity, the models are the same in this instance. class ObjectA(models.Model): text = models.TextField() pub_date = models.DateTimeField('date published',auto_now_add=True) ... class ObjectB(models.Model): text = models.TextField() pub_date = models.DateTimeField('date published',auto_now_add=True) ... class ObjectC(models.Model): text = models.TextField() pub_date = models.DateTimeField('date published',auto_now_add=True) ... What would be the general idea to serialize lists of all three objects into one list ordered by pub_date using the Django REST Framework. I just have experience using the meta version below but it can only deal with one model I am assuming. Thanks in advance. class ObjectAListSerializer(serializers.ModelSerializer): class Meta: model = ObjectA fields = [ 'text', 'pub_date' ] Pretty much trying to create something that would work like this: class AllObjectsListSerializer(serializers.ModelSerializer): -

Using django widgets with the django form builder
See here: https://github.com/stephenmcd/django-forms-builder and here: https://github.com/furious-luke?tab=overview&from=2017-01-01&to=2017-01-15 I am trying to have a field for a users street address on a django form. This input needs to be validated by google maps. I'm at a loss at how to combine the django address widget into the forms builder. I know it involves these two settings fields: FORMS_BUILDER_EXTRA_FIELDS = and FORMS_BUILDER_EXTRA_WIDGETS = but nothing I have put in either has allowed me to access the field (but I do get an assortment of errors). Any ideas or input would be greatly appreciated. -
Trouble setting up Django-Assets / Webassets and directory locations
Was looking for a Python package for Django to manage assets, using Sass to compile CSS, and also cache busting, and Django-Assets / Webassets was recommended. Having trouble getting it setup though with my directory structure. By default it looks for assets.py in each installed app. I want to set it up so that it sits in the same directory as settings.py and compiles app specific assets from each app directory into /static/js and /static/css. I have django_assets in INSTALLED_APPS. According to the docs it looks like I needed to add this to settings.py: ASSETS_MODULES = [ 'project_dir', ] Or: ASSETS_MODULES = [ os.path.join(BASE_DIR, 'project_dir'), ] Or: ASSETS_MODULES = [ PROJECT_ROOT ] At any rate, it just returns No asset bundles were found. If you are defining assets directly within your template, you want to use the --parse-templates option. Even moving the assets.py into one of the app directories, it is looking in BASE_DIR/scripts which is where I keep my manage.py. Again, changing ASSETS_ROOT doesn't really same to be doing anything. ~/portal-client project_dir apps account templates account login.html forms.py urls.py views.py home templates home home.html urls.py views.py results assets.py settings.py urls.py scripts manage.py static templates base.html footer.html title.html -
How to deploy my python machine learning code in website form
Can somebody point me in the right direction on how I can set up my machine learning code into a user friendly website for example using the famous University of California Irvine data for breast cancer ready to be used for researchers. A researcher can simply enter the values and get the result for the tumor another good example there are a lot of sentiment analysis websites using NLTK you just paste your text and a positive or negative result will appear. I want my code to be user friendly on a website a simple Q&A and get your result.

How to delete all data from a table in django inside a scrapy spider
I have this scrapy spider that populates a table, 10 to 20 records maximum get scraped and inserted into the table. So I figured instead of seeing if a record exists and update it, it would be faster just to get rid of them and scrape new ones to take their place, what would you think is the better option seeing as how I practically have no data in my table? Also what is the django orm command to delete with the help of a where clause, e.g delete all records that have "cat" as name? Thank you very much -

How to manage email from within AngularJS + Django?
I am working on a web app with AngularJS (1.x) and Django on the back-end, using the Django Rest Framework as API. I want to be able to manage any email account that's connected through IMAP/POP/SMTP protocols from within the app. So once you log in, you can view your email, receive, and send emails without - for example - having to go the gmail website. No idea where to start really, as most of the information I find online is only for automated registration and welcome emails. Do I need to set up a separate server? Should this live in Angular or mostly on Django? Etc... Any help would be greatly appreciated. -
Django View Does Not Populate In Template
I am following this book for some Django tutorials: https://www.packtpub.com/web-development/django-example I run into problems when trying to run the code for Chapter 1. Namely, everything works except for the Blog entries stored in database. They do not show up on the rendered page. Initially, I thought that I had made a mistake somewhere, so I downloaded the code that comes with the book and gave it a go. It behaves the same way. Could this be a version issue for Django? I installed the one recommended by the book. In case there is a code issue, I include some pertinent files below. Any help of suggestion is welcome. 1) views.py from django.shortcuts import render, get_object_or_404 from .models import Post # Create your views here. def post_list(request): posts = Post.published.all() return render(request, 'blog/post/list.html', {'posts': posts}) def post_detail(request, year, month, day, post): post = get_object_or_404(Post, slug=post, status='published', publish__year=year, publish__month=month, publish__day=day) return render(request, 'blog/post/detail.html',{'post': post}) 2) urls.py from django.conf.urls import url from . import views urlpatterns = [ # post views url(r'^$', views.post_list, name='post_list'), url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/'r'(?P<post>[-\w]+)/$', views.post_detail, name='post_detail'), ] 3) models.py from django.db import models from django.utils import timezone from django.contrib.auth.models import User from django.core.urlresolvers import reverse # Create your models here. class PublishedManager(models.Manager): … -
Django csrf_exempt not working
