Am I using get_or_create correctly?
Trying to use a single view for update and create operations. I employ two different urls: url(r'^update/(?P<pk>[0-9]+)/$', BoardUpdateView.as_view(), name='board-update'), url(r'^update/$', BoardUpdateView.as_view(), name='board-create'), Then I use this as my class: class BoardUpdateView(UpdateView): model = Board fields = ['author'] context_object_name = 'board' def get_object(self, queryset=None): if "pk" not in self.kwargs: self.kwargs['pk']=None obj, created = Board.objects.get_or_create(pk=self.kwargs['pk'], defaults={'author': self.request.user}) I know there are many ways to use Python, but I wondered if this approach is going to lead to any issues, or if there is a more idiomatic way to do this? For example, my check for whether pk exists or not seems weird/gross. -
How to insert variable into Django template and test whole HTML at client side?
I would like to front-end of my Django project. However, some DOMs specified in template and some DOMs generated in front-end JavaScript (mainly jQuery). At the same time, in Django template, some variables need to be queried from the database. I would like to know how to test whole front-end without setting the database. That is, just insert variables into template and test them at client side (i.e. load JavaScript as well, I mean). I know the Django support test cases on template and suggest using selenium on client side, but I don't know how to combine them and apply in my scenario at ease. I prefer use python library if possible, because not all members of our project know hot to program JavaScript, but all suggestions are welcome still. To be specific, I want to test this JavaScript file, which is loaded in this template. Therefore, var dataset_list = {{ blastdb_list|safe }}; var blastdb_type_counts = {{ blastdb_type_counts|jsonify }}; Load the variable, but I want to insert some already known value and write test of that javascript. As you see, that JavaScript mainly use JQuery and manipulate some DOMs. Can someone give some directions and live examples if possible? Thanks … -
Can't edit slug field in Django Admin
I have a Django app with a model that has a slug field. Up until now, I have been simply slugifying the model's label field, and making the slug read only in the admin. My client now wants me to allow them to be able to edit the slug themselves to whatever they want. I took off the readonly access in the admin, and changed the save method on my model to not use its slugified label. When I go to the admin however, and try to change the slug, it doesn't change when I save it. When I try to add a new model instance, even when I enter in something, it empties out the form field, and says that the slug field is required. I read in the Django documentation that it is custom to pre-populate the slug field, but it didn't say anywhere that it was required. Model class WebPage(models.Model): template = models.CharField(max_length=50, blank=True, null=True, choices=TEMPLATE_CHOICES, default='default') label = models.CharField(max_length=100) slug = models.SlugField(unique=True) meta_title = models.CharField(max_length=100, blank=True, null=True, help_text='This shows at the top of the browser, usually in the tab.') meta_description = models.CharField(max_length=180, blank=True, null=True, help_text='Optimal length is roughly 155 characters') meta_tags = models.CharField(max_length=500, blank=True, null=True) billboards … -
NoReverseMatch but nothing seems to be wrong
I keep getting this error: NoReverseMatch at / Reverse for 'login' not found. 'login' is not a valid view function or pattern name. But nothing in my code seems to be wrong, and in everything I have found on here and elsewhere the main problems are people not putting in the namespace into their urls.

value too long for type character varying(10) when it is set to 255
In models.py class Photo(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) id = models.CharField(max_length = 35) name= models.CharField(max_length = 255) I checked in manage.py dbshell within heroku, it says character varying (35) and character varying (255) respectively. I'm running out of thoughts as to why it is like this. Local runs just fine. It is when I deploy it to heroku, I get this error. I've also tried deleting the entire db in heroku and restarting everything all over. That did not work either. -

Django REST api calls and allowed_hosts
I'm trying to implement a RESTful API in Django such that any ip could query the endpoints. However, I'm concerned about header attacks if I were to set ALLOWED_HOSTS = ['*']. I read an answer to Why is Django throwing error "DisallowedHost at /"? which suggests that api calls should be responded to, not for by the server. I don't full comprehend what they mean or how to implement it and am looking for suggestions. Ultimately, I want to know how can I make an api call which is not blocked by django because it is not in ALLOWED_HOSTS? -

No such table when creating the public user accounts by Mezzanine for Django web dev

UI Bootstrap dropdown for Angularjs shows multiple values repeatedly in Django
I am trying to create a UI bootstrap dropdown in a Django project. This is my html code: <div class="container"> <div ng-controller="mainController"> <div class="btn-group" uib-dropdown is-open="status.isopen"> <button id="single-button" type="button" class="btn btn-primary" uib-dropdown-toggle ng-disabled="disabled"> Discrete Distributions <span class="caret"></span> </button> <ul class="dropdown-menu" uib-dropdown-menu aria-labelledby="simple-dropdown"> <li ng-repeat="discrete in discretes"> <a href>{% templatetag openvariable %} discrete {% templatetag closevariable %}</a> </li> </ul> </div> </div> </div> And this is my js code: var stats = angular.module('stats', ['rzModule', 'ui.bootstrap']); stats.controller('mainController', ['$scope', '$log', function($scope, $log){ $scope.discretes = ['Bernoulli', 'Binomial', 'Multinoulli', 'Multinomial', 'Geometric', 'Poisson']; }]); Output looks like the below picture. I tried all dropdown codes in here. I am new at both Angularjs and Django but I think it is about Django. Unfortunately I couldn't find the reason. Please help me to find it. -

How does {% url 'x' y %} function in Django?
In the Django tutorial (https://docs.djangoproject.com/en/1.11/intro/tutorial03/), we are advised not to "hard code" urls in our templates. For example, this snippet: <ul> {% for question in latest_question_list %} <li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a></li> {% endfor %} </ul> should be replaced by: <ul> {% for question in latest_question_list %} <li><a href="{% url 'detail' question.id %}/">{{ question.question_text }}</a></li> {% endfor %} </ul> However, the tutorial doesn't do a great job of explaining what actually happens here. The first example was clear, {{ question.id }} would take the value of the question id and it would be placed in the url. But in the second snippet, we are using the keyword (is it called a keyword?) url and also doing something with 'detail', which I'm not sure where it comes from, though I suspect it has something to do with this: urlpatterns = [ ... url(r'^(?P<question_id>[0-9]+)/detail/$', views.detail, name = 'detail'), ] So, my question is what is happening in {% url 'detail' question.id %}? -

Django-allauth - How do I get the form errors from Ajax?
Using django-allauth, how do I obtain form errors via AJAX login?

I have a RESTful API on Django and I would like to know how to reference an existing ForeignKey when using json in HTTP POST? class Trainer(models.Model): account = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True, related_name='profiles') username = models.CharField(max_length=30, unique=True, primary_key=True) start_date = models.DateField(default=date(2016,7,13), null=True, blank=True) faction = models.ForeignKey('Faction', on_delete=models.SET_DEFAULT, default=0, null=True, verbose_name="team") has_cheated = models.BooleanField(default=False) last_cheated = models.DateField(null=True, blank=True) currently_cheats = models.BooleanField(default=False) statistics = models.BooleanField(default=True) daily_goal = models.IntegerField(null=True, blank=True) total_goal = models.IntegerField(null=True, blank=True) last_modified = models.DateTimeField(auto_now=True) prefered = models.BooleanField(default=True, verbose_name="main profile") def __str__(self): return self.username class Faction(models.Model): name = models.CharField(max_length=140) colour = RGBColorField(default='#929292', null=True, blank=True) image = models.ImageField(upload_to=factionImagePath, blank=True, null=True) leader_name = models.CharField(max_length=140, null=True, blank=True) leader_image = models.ImageField(upload_to=leaderImagePath, blank=True, null=True) def __str__(self): return self.name This are the relevant models, I have a list of 4 Faction objects, with their primary keys being 0, 1, 2 and 3. I've tried many different way, but I just can't figure it out. This was my latest try, can you advice where I'm going wrong? { "username": "Bob123", "faction": "1" } Returned { "username": "Bob123", "faction": "Teamless", "start_date": "2016-07-13", "has_cheated": false, "last_cheated": null, "currently_cheats": false, "statistics": true, "daily_goal": null, "total_goal": null, "last_modified": "2017-09-08T21:05:18.001389Z", "prefered": true, "account": null } -
Confusion on getting Javascript to see a lsit of lists from Python via JSON as such
I am working on a Django app. I need to pass back a few parameters from the server, which I do with this code: num_periods = 25 num_traces = 2 opacities = [0.5, .99] ys = [[1,2,3,4,5],[7,6,5,4,3]] response = {'text' : request.POST['value'], 'num_periods' : num_periods, 'num_traces' : num_traces, 'opacity': opacities, 'ys': ys } return JsonResponse(response) On the client side, in the Ajax callback, I have code that looks like this: success : function(data) { console.log('num traces = ' + data.num_traces); console.log('opacitiees = ' + data.opacity); console.log('data = ' + data.ys); but, console.log(ys) gives data = 1,2,3,4,5,7,6,5,4,3, which looks flattened. However, if I do console.log(ys[1]), it 'looks like' an array: 7,6,5,4,3, though with no brackets. So, JS is aware of the nested list structure. But any attempt to get it into a list of lists of numbers fails. for example this code: z=[] z.push(ys[0]) z.push(ys[1]) gives me back z = 1,2,3,4,5,7,6,5,4,3 when I do console.log("z = " + z) Something deeply confusing is happening here. I also tried Object.values(ys[0]), but still this does not give a list. Other ideas I have seen are a clever use of slice like so : var ys=[]; while(list.length) ys.push(list.splice(0,5)); console.log("ys[0]="+ys[0]); which gives ys[0]=1,2,3,4,5,7,6,5,4,3 How do …
