Error: Django model form data not being saved in the database
I'm trying to create a blog model but the form data is not being saved in the database after submitting the form. views.py def postsform(request): if request.method == "POST": form = BlogForm(request.POST) if form.is_valid(): form.save() return redirect('blog') else: form = BlogForm() messages.warning(request, "Opps!

Django: Forloop Counter 0 divisible by 3 not working properly
PLATFORM: Django Problem When using {% forloop.counter0|divisibleby:3 %} it doesn't seem to properly divide out? I can't quite tell what's going on. Goal Display an Avery HTML template with pre-populated info from the database. 3 column table with variable rows. Code <table> {% for job in jobsite %} {% if forloop.counter0|divisibleby:3 %}<tr>{% endif %} <td>{{ job.name }}<br/>{{ job.address }}<br/>{{ job.address_2 }}{% if job.address_2 %}<br/>{% endif %}{{ job.city }}, {{ job.state }} {{ job.zip }}</td> {% if forloop.counter < 3 %} <td class="spacer" rowspan="0">&nbsp;</td> {% endif %} {% if forloop.counter0|divisibleby:3 or forloop.last %}<tr>{% endif %} {% endfor %} </table> Why is this failing? Additional Info I can get close if I change the code around to the following. The problem then becomes that counter 2 is blank. If I fill in data, it's duplicated (row 1 column 2, row 1 column 3): <table> <tr> {% for job in jobsite %} {% if forloop.counter|divisibleby:3 %}</tr><tr>{% endif %} <td>{{ job.name }}<br/>{{ job.address }}<br/>{{ job.address_2 }}{% if job.address_2 %}<br/>{% endif %}{{ job.city }}, {{ job.state }} {{ job.zip }}</td> {% if forloop.counter < 3 %} <td class="spacer" rowspan="0">&nbsp;</td> {% endif %} {% if forloop.counter == 2 %} <td></td> {# <td>{{ job.name }}<br/>{{ job.address }}<br/>{{ … -
How to count the number of specific objects in a Django model?
I have a Django model called User and would like to count how many items are within the following object. class User(AbstractUser): following = models.ManyToManyField("self", related_name="followers") I have tried counting them using this line followers_num = User.following.count(), but I receive this error 'ManyToManyDescriptor' object has no attribute 'count'. I have also tried followers_num = User.objects.all().count(), but that returns the number of users. Does anyone know how to do this? -

How would I get sum from all rows, but only output one row? Django and Postgresql
currently the way I have the code written is that I have a model named Finances. I have an aggregate set up so it sums up all of the rows. I am trying to display the outcome of the rows, but when I do it displays a row for every database entry. I understand that I am grabbing all with .all() in the viewpayout = Finances.objects.all() in views.py, but I am unsure of how this should be written to only display one row.

Conversion from Markdown to HTML in Django project
I'm on a project which include use of Python, Django, HTML and Markdown. I have to develop a site similar to wikipedia, in fact the project is called encyclopedia. My goal is to make visiting / wiki / TITLE, where TITLE is the title of an encyclopedia entry, to display a page that displays the content of that encyclopedia entry. The encyclopedia entries are CSS Django Git HTML Python (each entry has its own .md file). the problem I have is with the "markdown" library. In practice, I was able to convert the syntax from markdown to HTML but as output I only receive the tags in written format, without them applying their standard style to the content inside them.

How Can I do PIN Activation, user registration and Authentication in Django
I am working on a Django project where users would have to activate PIN and then register for an event seat. I have done it in such a way that users activate PIN and they are prompted with registration form to secure a seat for an event. And I want to get the Event name, Price, Date, category from the Ticket table. Meanwhile I have a Guest Model that is saving username and pin using an update query during the registration process; using a forms field to request for PIN again (Don't want to repeat this process too). And I have used the pin field as a ForeignKey in the Guest Model so I am getting error that Cannot assign "'384513'": "Guest.pin" must be a "Pin" instance. What is the best way of doing this logic of PIN activation, registration and authenticating a user and getting the Models values associated with his PIN in this case. I was thinking of using the Guest Table to get the information relating to Events, Ticket and Pin Details but no way. See below Models code: class Ticket(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE) price = models.PositiveIntegerField() category = models.CharField(max_length=100, choices=PAYMENT, default=None, blank=False, null=False) added_date = … -
Explicitly defining fields on ModelSerializer overrides Model's parameters like verbose_name and validators
Imagine having a simple model like the one bellow: from utils.validators import name_validator class Customer(models.Model): name = models.CharField(verbose_name="Customer Name", validators=[name_validator]) email = models.EmailField(verbose_name="Customer Email") def __str__(self): return self.name Now if I explicitly define a filed on my serializer, both validators and verbose_name are lost. I can use label= and validatos= when defining the field on my serializer but I don't want to repeat myself. What if I have multiple serializer pointing to the same Model? class CustomerSerilizer(serializers.ModelSerializer): custom_field_name = serializers.CharField(source="username") class Meta: model = Customer fields = "__all__" Is there anyway to prevent this from happening? -
Wagtail - Override internal links in richtexteditor
Since I use wagtail headlessly the internal links get messed up due to them using the site-url listed in settings. Instead, I want to be able to override that same URL and point them to my frontend. This post talks a little bit about it in 2018, but I'm hoping this has changed? Wagtail: Is it possible to disable prepending internal link's with the site domain? For external links you'd do something like this to override it: class NewWindowExternalLinkHandler(LinkHandler): # This specifies to do this override for external links only. identifier = 'external' @classmethod def expand_db_attributes(cls, attrs): href = attrs["href"] print(attrs) # Let's add the target attr, and also rel="noopener" + noreferrer fallback. # See https://github.com/whatwg/html/issues/4078. return '<a href="%s" target="_blank" rel="noopener noreferrer">' % escape(href) Is it possible to do the same for internal links? E.g now since I use a multi-site setup my link looks something like: https://localhost.my-backend-api-domain.com/page/pagename I want it to look like this: https://my-frontend-domain.com/page/pagename -
Post only unique key value pairs to redis instance
I am POSTing a list of key values pairs to a redis_instance. I would like to first check if any of the keys/values I am posting to redis already exist to avoid having duplicate key value pairs or instances where a pre-existing key has a different value or a pre-existing value has a different key so for example avoiding scenarios like this: Fred: Luke Luke: Jim Jim: Jane and instead only allow these pairs to be written to my redis_instance: Fred: Luke Jim: Jane This is what I have: @api_view(['GET', 'POST']) def manage_items(request, *args, **kwargs): if request.method == 'GET': items = {} count = 0 for key in redis_instance.keys("*"): items[key.decode("utf-8")] = redis_instance.get(key) count += 1 response = { 'count': count, 'msg': f"Found {count} items.", 'items': items } return Response(response, status=200) elif request.method == 'POST': item = json.loads(request.body) keys = list(item.keys()) values = list(item.values()) for i in range(0, len(keys)): redis_instance.set(keys[i], values[i]) response = { 'msg': f"{keys} successfully set to {values}" } return Response(response, 201) not quite sure how to carry this out -

How to properly migrate a monolith architecture app to a microservice app in Django
Today I come with this question probably to someone who has large experience in this. Basically what the title indicates. We have that app and we have to migrate it to microservices. We didn't find any solid approach (or we felt it like that) about this. What we ended up doing is creating 1 project per microservice (a single functionality related to a module app, in general) but then we had some problems because we already had a database to work with since this is already a functioning app. We had problems communicating with the existing models, so basically what we did was to point in every settings.py of the projects to the existing DB, and with python3 manage.py inspectdb, we grabbed the existing models. This approach ended up working, but we feel that is not the best approach. We had a lot of problems with circular imports and more. Is out there good practices about microservices with Django, and how to properly do it, like in most of the cases that we want to create something with the framework? If someone knows or has something we would really appreciate it! -

Image of error when I run it on Mozilla firefox and this is what it is saying in terminal Image of error in terminal and this is the line of chatpage urls.py line which is I am trying to display with username path('ChatView/<str:uname>', login_required(views.ChatView.as_view()), name="chatpage"), and this is the line of views.py for chatpage. class ChatView(View): def get(request, username): uname = User.objects.get(username=username) return render(request, 'chatbot/chatPage.html', { 'uname': uname }, context_instance=RequestContext(request)) and this is the Html code that I use for username input: <input class="w-full text-lg py-2 border-b border-gray-300 focus:outline-none focus:border-indigo-500" type="text" placeholder="Enter Your Username" id="username" name="username" value="{{data.username}}" Required> These are the four links of pastebin for whole code: views.py urls.py chatpage.html signin.html
