Modify Django for loop every four iterations
I have a calendar generated by Django and styled with Bootstrap. Here is the code in the Django template : <div class="content"> {% for month in period.get_months %} <div class="col-md-3"> <div class="row row-centered"> <button class="btn btn-custom active" href="{% url "month_calendar" calendar.slug %}{% querystring_for_date month.start 2 %}">{{month.name}}</button> </div> <div> {% month_table calendar month "small" %} </div> </div> {% endfor %} </div> Now, since months have a different number of weeks they have different heights I would like to avoid something like this: I understand from this answer that the best solution would be to use a clearfix. So, how can I modify the for loop in my template so that Django inserts an extra line <div class="clearfix"></div> every four items? -

How does django know which user owns what data?
If for example I want to show a zero(0) for all users to see, and I want all users to add one(1) to the number With their Identity only shown for superusers. And how to make sure that each user only can add one time, and of course what is the Security requirements that have to be done to prevent unautohrized Access to change any of this or to get any information? I understand this is a big topic, but could someone briefly explain for me what parts of Programming that are involved, and maybe some good books on these topics? Excuse me my English, and thanks for any help! -

Django DRF HyperLinkedRelatedField referencing a specific model's source id
In the TrackSerializer class below from serializers.py, I'd like to have a url field that creates a hyperlink to the related Artist.id but it's creating a hyperlink to the Track.id instead even when I specify queryset=Artist.objects.all() in the HyperLinkedRelatedField.

How do I prefetch related objects for a list of already fetched ones?
I'm displaying 7 random objects on a home page. For that I use solution based on this answer: class ProductManager(models.Manager): def random(self, n_products, filter={}, select_related=None): n_products_total = self.filter(**filter).count() if n_products_total == 0: return [] r = [self.random_impl(n_products_total, filter, select_related) for i in range(n_products)] return [p for p in r if p is not None] def random_impl(self, n_products, filter, select_related=None): random_index = randint(0, n_products - 1) try: return self.filter(**filter) \ .select_related(select_related)[random_index] except IndexError: return None random_products = Product.objects.random(7, filter={'enabled': True}, select_related='category') If I pass prefetch_related=Prefetch('productphoto_set', queryset=ProductPhoto.objects.order_by('pk')) to random_impl method, it prefetches 1 photo at a time for each product. Which is not surprising. Can I prefetch related objects manually after products has already been fetched? -

How to tell django app where my react-ootstrap fonts are?
I am using react-boostrap and I want to use bootstrap glyphicons. Currently I haven't been able to render glyphicons on front-end.The issue that I've tracked down is that the fonts aren't being loaded from the correct URLs. Front-end is using this url http://0.0.0.0:8000/448c34a56d699c29117adc64c43affeb.woff2 [returns 404 obviously] it should have been: http://0.0.0.0:8000/static/448c34a56d699c29117adc64c43affeb.woff2 Here is my webpack.config.js. So how do I tell the front-end where to load the fonts from? -
Many-to-Many Misunderstanding in Django
I am new to web development so this question might not be straightforward but please bear with me. Im working on a social network in which a user could follow another user in two different ways...anwyways...i created two models to define the relationships. A many-to-many relationship as follows. How do i make this models totally independent of each other? so lets say a user could have 500Followers and 200Guests?? i used th javascript code below to toggle the follow button but its increases both. This might not be a great overview of the problem but thats because i am new to this. but please try. I am using django by the way. class Follower(models.Model): user_from = models.ForeignKey(User, related_name='rel_from_set') user_to = models.ForeignKey(User, related_name='rel_to_set') created = models.DateTimeField(auto_now_add=True, db_index=True) class Meta: ordering = ('-created',) def __str__(self): return "{} is now a following".format(self.user_from, self.user_to) class Guests(models.Model): user_fromt = models.ForeignKey(User, related_name='yel_from_set') user_tot = models.ForeignKey(User, related_name='yel_to_set') created = models.DateTimeField(auto_now_add=True, db_index=True) class Meta: ordering = ('-created',) def __str__(self): return '{} follows {}'.format(self.user_from, self.user_to) User.add_to_class('follows', models.ManyToManyField('self', through=Guests, related_name='guest', symmetrical=False)) User.add_to_class('follows', models.ManyToManyField('self', through=Follwer, related_name='guest', symmetrical=False)) View def user_follow(request): user_id = request.POST.get('id') action = request.POST.get('action') if user_id and action: try: user = User.objects.get(id=user_id) if action == 'follow': Contact.objects.get_or_create(user_from=request.user, user_to=user) create_action(request.user, … -

Phantom Brackets in Ajax Call when sending an Array to Django
I am trying to send a normal javascript array through an Ajax call and something weird is happening. Here's my function: // Save new Strategy $('.tab-pane').on('click', 'button.saveStrat', function() { var stratType = $('#typeValue').val(); // Set by newEntry method in swot-nav.js var label = $('#newStratLabel').val(); // Form element in new_swot_modal.html var details = $('#newStratDetails').val(); // Form element edit_swot_modal.html var entries = []; // Build a list of SWOT entries that the user has identified as associated to this strategy. $('input.entryCheckbox[type=checkbox]').each(function () { if (this.checked) { entries.push($(this).val()); } }); console.log(entries); $.ajax({ url: '/add_swot_strategy/', type: "POST", data: { 'type': stratType, 'label': label, 'details': details, 'entries': entries }, dataType: 'json', success: function (data) { appendNewItem(data, swotType) } }); resetAddForm() }); And here is how my Django test server receives it: <QueryDict: {'label': [''], 'type': ['A'], 'details': [''], 'entries[]': ['16', '23', '26']}> What's with the extra brackets after the entries label? Is this intended behavior? Can I go ahead and do it this way or am I breaking the rules? -

How to take data from a form in order to search and filter in MongoDB

Using django authentication system with existing data
I have a very old cgi/perl system with a user table. The passwords are stored as output (computed hash) of 'crypt' function. I am looking to migrate the system to Django. I would like to keep the user data while using the Django table structure. One option would be to copy all the user/password data to 'auth_user' table and use a custom authentication function since I have existing passwords generated with crypt. Do I have a better option? Also, if I go with the option I have described above, how can this be implemented? -

beginner django -> retrieve data from SQL db
So, I just followed a tutorial that helped me set up my Django project, online. The "templates" are now available online, on a VPS called "vultr". On the same server, I have a SQL database with some data. I would like to know how can I make one of my Django templates retrieve the data from the SQL database and show them? I've tried looking up on Google, but I'm still a beginner and it's really too hard for me to understand and pick the rights info's that fits me. Thanks -
Django aggregation to retrieve queryset based on identical start and end times
I have a model which looks like this: class Event(models.Model): date = models.DateField(blank=True, null=True) start_time = models.TimeField(blank=True, null=True) end_time = models.TimeField(blank=True, null=True) I am trying to compose a single line command which would retrieve a list or query set of all Event objects in my database, where every element in a subset is grouped by an identical date, start_time, and end_time, and the elements of each subset should be ordered by start_time. I have been trying to use Django aggregations, but unable to get things to work right. Is this possible with aggregations, and if so, how would I do it best? -
Parsing and displaying nested JSON in Django Template
I am trying to print the results of an API call which is returning JSON results nested relatively deeply. I am doing this project with Python 2.7 and Django 1.11. I have the following view.py function: def nlu_analysis(request): if request.method == 'POST': text2send = request.POST.get('text2send') natural_language_understanding = NaturalLanguageUnderstandingV1( version='2017-02-27', username='####', password='####') response = natural_language_understanding.analyze( text=text2send, features=[features.Entities(), ..., features.SemanticRoles()]) return render(request, 'watson_nlu/analysis.html', {'data': response}) When I use the following template code in my .html file: {% for k in data.keywords %} <p>Text - {{ k.text }}</p> <p>Relevance - {{ k.relevance }}</p> {% endfor %} to parse and display JSON with one level of nesting like this: 'keywords': [{ 'relevance': 0.946673, 'text': 'eyes' }] Everything is great and it displays 'eyes' and 0.946673 as expected. I can't figure out the appropriate syntax for getting to the 'anger', 'joy', etc. results that are nested more deeply such as this: { 'emotion': { 'document': { 'emotion': { 'anger': 0.195192, 'joy': 0.082313, 'sadness': 0.644314, 'fear': 0.207166, 'disgust': 0.103676 } } } What is the most efficient method for accomplishing this objective? It is definitely NOT: <p>Anger - {{ data['emotion.document.template.anger'] }}</p> Advance newbie gratitude and good juju for your help. -
security user registration django rest endpoint
I want to implement a user registration endpoint using django rest framework. The endpoint would be public and anyone could potentially register a new user to be able to access the restricted version of the site. The registration endpoint would take a POST action and a JSON object containing let's say first name, last name, email and password. The problem is because of the nature of the endpoint being public someone could program a pyCurl script to create a bunch of new users, I want to avoid that. How can I secure my endpoint properly to avoid that? I have no idea at the moment on what course of action to take. I could make a registration page using CSRF and a django template. That could be a solution and let the rest of the application could run under angular2. Ideally I want to avoid that. any ideas? thanks -

Django: proper way to handle form with POST to the same page
I am new to Django and have completed the 7 part tutorial on their website. Part four of their tutorial introduces a form on the page details which posts to votes (a view that does not display anything) and then returns results on success or otherwise returns you to details.
