Django Photologue XML Error
Does someone know why I get an XML-Error when I try to open a picture via Django-Photologue? Unfortunetly the Error message is in German: XML-Verarbeitungsfehler: nicht wohlgeformt Adresse: http://example.com/photologue/photo/name_of_photo/ Zeile Nr. 1, Spalte 1: before it said instead of something like <!Doctype html> so I assume it has something to do with a certain template of photologue. How can I fix this? -

Add 'yesterday' field to Django admin date list filter
In my Django application, in the admin, for one of my models, I am allowing the option to filter by its 'create_date' field. Django by default gives me some options (Today, Past 7 Days, This Month, This Year). I want to simply add the option to choose 'Yesterday' as well. I looked at other Stack overflow questions regarding the same issue, but they were all looking for the ability to search by a date range, and I only want the one preloaded option. Is their a way in the admin class that configures this model to override some of their filter functionality ? Admin Class class User_LikeAdmin(admin.ModelAdmin): def fb_view_link(self, obj): if len(obj.user_facebook_link) > 2: return u"<a href='%s' target='_blank'>Facebook Page</a>" % obj.user_facebook_link else: return "" fb_view_link.short_description = '' fb_view_link.allow_tags = True list_display = ('vehicle', 'user', 'fb_view_link', 'dealer', 'create_date') list_filter = ('create_date', ('vehicle__dealer', custom_titled_filter('Dealer'))) raw_id_fields = ('vehicle', 'user') actions = [export_csv] def dealer(self, obj): return obj.vehicle.dealer -
Travis CI Django Build Fails

Header image and Table Header missing when overflowing using [xhtml2pdf]
As the title says, I'm building a generic invoice pdf using xhtml2pdf and django. The image and table headers display correctly on the first page, but when the main table overflows, the image and table header aren't repeated.

Get value of label from Django form
I've created a CustomChoiceField from a queryset in Django with a custom label that passes the name, url, and aspect attributes of each object into the label. Here's the relevant code from forms.py: class CustomChoiceField(forms.ModelChoiceField): def label_from_instance(self, obj): return mark_safe("%s<img src='%s' class='teams__filter__image' value='%s'/>" % (obj.name, obj.image.url, obj.aspect)) filter_pic = CustomChoiceField(required=False, label=mark_safe('Image Filter'), widget=forms.RadioSelect(attrs={'id':'filter-choice'}), queryset=FilterPic.objects.filter(activated=True), empty_label='None') It renders in HTML like so: <p class="teams__form__label">Image Filter</p> <p><label for="filter-choice_0"><input checked="checked" id="filter-choice_0" name="filter_pic" type="radio" value="" /> None</label></p> <p><label for="filter-choice_1"><input id="filter-choice_1" name="filter_pic" type="radio" value="2" /> WeHealth Orange<img src='/media/images/2017/08/28/orangefilter.png' class='teams__filter__image' value='0.7'/></label></p> <p><label for="filter-choice_2"><input id="filter-choice_2" name="filter_pic" type="radio" value="1" /> WeHealth Blue<img src='/media/images/2017/08/28/bluefilter.png' class='teams__filter__image' value='0.7'/></label></p> Everything looks great in HTML. The problem, is that I need the aspect attribute (current the value attribute in the label) in order to trigger a subsequent Javascript function (cropper.js aspect ratio). How can I obtain the aspect value in Javascript? -
Django API REST Framework : Generate a string based on CreateAPIView
I'm looking to use Django API REST Framework in my web application but I get an issue in my project. In my application, I fill a Django form in order to register a new person in my database. My model looks like : class Individu(models.Model): NumeroIdentification = models.CharField(max_length=30, null=True, verbose_name='Numero Identification physique', unique=True) Civilite = models.CharField(max_length=12,choices=CHOIX_TITRE, verbose_name='Civilité') NomJeuneFille = models.CharField(max_length=30, verbose_name='Nom de jeune fille', blank=True) Nom = models.CharField(max_length=30, verbose_name='Nom de famille') Prenom = models.CharField(max_length=30, verbose_name='Prénom(s)') Sexe = models.CharField(max_length=30, choices=CHOIX_SEXE, verbose_name='Sexe') Statut = models.CharField(max_length=30, choices=CHOIX_STATUT, verbose_name="Statut civil") DateNaissance = models.DateField(verbose_name='Date de naissance') VilleNaissance = models.CharField(max_length=30, verbose_name='Ville de naissance') PaysNaissance = CountryField(blank_label='Sélectionner un pays', verbose_name='Pays de naissance') ...

Incorporating "Like Post" feature
Hey so I am making a color scheme posting site where people can register and post color schemes they come up with. So far everything is working great, the only thing I have left to do is add a "Like Post" feature. I'm wondering what the best way to implement this would be. I have two ideas on how this could be done, the first is add an additional field to both the ColorSet (posts) and the User models (for the user model I would set up a new model with a OneToOne relationship to add onto the User model) which would record users that have each single post, and which posts each user has liked to keep track of everything. So this could look something like this: from django.db import models from django.core.urlresolvers import reverse from django.conf import settings from django.contrib.auth import get_user_model User = get_user_model() # Create your models here. class ColorSet(models.Model): user = models.ForeignKey(User,related_name='colorset') published_date = models.DateTimeField(auto_now_add=True) name = models.CharField(max_length=50,blank=False) color_one = models.CharField(max_length=6,blank=False,default='cccccc') color_two = models.CharField(max_length=6,blank=False,default='ffffff') color_three = models.CharField(max_length=6,blank=False,default='e5e5e5') color_four = models.CharField(max_length=6,blank=False,default='f0f0f0') color_five = models.CharField(max_length=6,blank=False,default='bababa') liked_by = models.IntegerField(blank=True) def publish(self): self.save() def get_absolute_url(self): return reverse('index') def __str__(self): return self.name user model: from django.db import models from django.contrib.auth.models … -
Django filter datetime elements
I use django 1.11.2 for my project. I had defined some models and all work right. Now I need to get some data from one of my models by date. For example all entry wich have month=8, month=9.... I have this, MyModel(....some fields...., created_date) and in models.py I have: .... created_date=models.DateTimeField() .... .... self.created_date=(datetime.now()) .... Created_date is a datetime field and its values are in this format: YYYY-MM-DD HH:MM:SS, for example 2017-08-31 14:25:58. So, I see this: https://docs.djangoproject.com/en/1.11/ref/models/querysets/#month And this will be perfect for me, but don't work. From shell I write this: >>> from project.models import MyModel >>> from datetime import * >>> MyModel.objects.all() ---> Work ok, I get all entries >>> MyModel.objects.filter(created_date__month=7) <QuerySet []> In this case I get an empty Quertset. -
Sessions handle datetime like django wizard
I'm using sessions in a current django project and recently got a 'Object of type 'date' is not JSON serializable' error - due to the move_in_date field When saving a modelform of the below model to the session via: if form.is_valid(): request.session.update(form.cleaned_data) my model: class Address(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL) house_name_number = models.CharField(max_length=255, verbose_name="house name or number") street_name = models.CharField(max_length=255) town_city = models.CharField(max_length=255) county = models.CharField(max_length=255) postcode = models.CharField(max_length=8) same_address = models.BooleanField() move_in_date = models.DateField(null=True, blank=True) Reading through the django docs on sessions I'm not clear why sessions use a serializer? (I'm using the db to store the session) From my understanding isn't just the session ID going to the browser in a cookie and the session data is stored in the db? The data in the session can be accessed via the ORM like a normal model. However when I look at the database table there is just one field, session_data (apart from expiry date and session id). Looking at the docs seems to be signed (but not encrypted? - not sure of the difference). So I'm not clear where the serializer is being used? Additionally I was using django wizard before which stores intermediate data (such as the field … -
elasticsearch.exceptions.RequestError: Mapping definition for [name_complete] has unsupported parameters: [payloads : true]

How to get CSRF token from mobile apps when CSRF_USE_SESSIONS is True ? (Django 1.11)
Good evening everybody, As a student group, we are developing an API using Django 1.11.2 and we would like to consume our API from mobile apps (such as Android applications). Currently, we are struggling getting the CSRF token from mobile applications, here's the background : We are using CSRF_USE_SESSIONS = True. From what I understand from the Django CSRF documentation, the token is stored in the session instead of a cookie. We are using the SessionMiddleware in which the SESSION_ENGINE is configured as 'django.contrib.sessions.backends.signed_cookies' For the big authentication part, we are using class-based views. In multiple templates, we are using {% csrf_token %} into forms in order to protect them during POST requests. Everything works great when consuming the API from a non-mobile web client. However, when consuming it from an Android application, we face multiple problems. What we tried so far was - during a GET request - getting the CSRF token from the session and sending it through Accept: 'application/json' : class Login(LoginView): form_class = AuthenticationForm template_name = 'users/login.html' def get(self, request, *args, **kwargs): if request.META.get('HTTP_ACCEPT') == 'application/json': csrftoken = request.session.get(CSRF_SESSION_KEY) return JsonResponse({ 'csrf-header-name': 'X-CSRFToken', 'csrf-token': csrftoken }, status=200) return super().get(request, *args, **kwargs) def post(self, request, *args, **kwargs): … -

POST request with a form action on another page returns 405, doesn't process request.POST
The idea is to display a search box, where a user can type in the address, which get's completed by Google Autocomplete. Then, we save the lat and long parameters and redirect to the /search (using POST) or (maybe use a GET request) alternatively /search?lat=xxx&long=xxx. For the second case, with URL parameters I could use lat = request.GET('lat') My Index.html form <form action="{% url 'users:index' %}" method="post" enctype="multipart/form-data"> {% csrf_token %} <input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on" runat="server" /> <input type="hidden" id="cityname" name="cityname" /> <input type="hidden" id="Lat" name="Lat" /> <input type="hidden" id="Lng" name="Lng" /> <button type="submit">Submit</button> </form> When user picks from the dropdown, the javascript gives me values of Lat , Lng and cityname.

Eg.: INFO 2017-08-31 11:52:40,725 arnaud basehttp "GET /design/projects/ HTTP/1.1" 200 3852 Unfortunately, it seems to be disabled when running a LiveServerTestCase. In order to ease the debugging of my end-to-end tests, I would like this feature to remain activated. -
Autocreate new database rows
My application creates several rows of data per customer per day. Each row is modified as necessary using a form. Several modifications to a row may take place daily. At the end of the day the customer will "commit" the changes, at which point no further changes will be allowed. In each row I have a 'stage' field, stage=1 allows edits, stage=2 is committed, no further changes allows. How can I update the stage value to 2 on commit? In my model I have: @property def commit_stage(self): self.stage = 2 self.save() Is this the correct way to do this? And if so, how to I attach this function to a "commit" button. -

Send data by post from AngularJs to Django
I want to send data from AngularJS to the back end (Django) via Http request. I tried many ways but I keep not getting the sent data when receiving the request in django. Before I paste my code, I just have changed the configurations in AngularJS in my project as the following var myApp = angular.module('myApp',[]).config(['$httpProvider', '$interpolateProvider', function ($httpProvider, $interpolateProvider) { $interpolateProvider.startSymbol('{/'); $interpolateProvider.endSymbol('/}'); $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';}]); The urls: urlpatterns = [ url(r'^save_comment/', views.save_comment, name='save_comment'),] Sending Https POST in Angular: $scope.submit_comment = function () { $http({ method: "POST", url: 'save_comment', data: $.param({ 'fish_id' : "1" }) }).success(function (response) { console.log(response.result); }).error(function () { console.log("failed") }); } Receiving the request in the Views def save_comment(request): data = request.POST.get('fish_id') return JsonResponse({'result': data}, content_type="application/json", safe=False) But I didn't get any result. the console gave me this error: POST http://127.0.0.1:8000/brain_browser/save_comment 500 (Internal Server Error) So what should I do to send Post data from Angular to Django? Thank in a dvance.
