Why attribute of a dictionary works in template html through connection with codes in view.py ?
I am new to Django, and I am following a tutorial in which he writes something like {%for post in posts %} {{post.author}}in the template html file. He describes that the template responds to the key 'posts'. To my understanding, post is a dictionary according to what he writes in view.py? How does it work? posts = [ { 'author': 'JosephJ', 'title': 'Blog Post1', 'content': 'First post content', 'date_posted': 'August 27, 2018' }, { 'author': 'RogerL', 'title': 'Blog Post2', 'content': 'Second post content', 'date_posted': 'August 28, 2018' } ] def home(request): context = { 'posts': posts } return render(request, 'blog/home.html', context) -

Django - how to access a ForeignKey parent's attribute?
I'm a newbie in Django, and I don't know how to this. I have a model 'Seller': class Seller(models.Model): seller_name = models.CharField(max_length=50) def __str__(self): return self.seller_name and a model 'Item': class Item(models.Model): seller = models.ForeignKey(Seller, on_delete=models.CASCADE) item_name = models.CharField(max_length=100) item_category = models.CharField(max_length=100, choices=ALL_CATEGORIES) item_price = models.FloatField() item_preview = models.ImageField(upload_to='previews/<the seller's name>') def __str__(self): return self.item_name connected via ForeignKey to Seller. In this model, I have an ImageField, and I want it to upload the files to previews/Seller's name directory, but I don't know how to access the Seller's name from Item. Is it possible? Or am I doing something I am not supposed to? Because I couldn't find any similar cases in the internet. -
Django TypeError missing 1 required positional argument: 'listing_id'
Django newbie here. For my first project, I'm following a course that I found online which is a website for finding properties, realtors and stuff.

Select distinct pairs from a MySQL table data in Django
I am writing a logistics application that tracks various routes, I want to write code that can find all the routes in the system. For example in the following database: From | To | Time Seattle | Chicago | 12PM Chicago | Seattle | 9 AM Seattle | Chicago | 2PM Chicago | Houston | 3PM The result should be: From | To Seattle | Chicago Chicago | Houston Basically, the direction doesn't matter, only the pairs do. I tried using join statements by using djangos raw() function but this prints out all the routes multiplied by the number of times that pair appears, so in the above example it would print out the 1st, 2nd and 3rd record 3 times each as well as the last record. fls = Route.objects.raw('SELECT * ' 'FROM manager_route f1, flights_flight f2 ' 'WHERE (f1.origin_id = f2.destination_id AND f1.destination_id = f2.origin_id)' 'OR (f1.origin_id = f2.origin_id AND f1.destination_id = f2.destination_id)') -
Testing form in Django with regex validation

Django 2.1 NOT NULL constraint when setting ForeignKey
I am setting FK to an object from a previous form submission, but I can't seem to figure out why I am getting a null constraint error.

django app is working while not included in settings.py
I am reading the tutorials for django on their site. In the first tutorial https://docs.djangoproject.com/en/2.1/intro/tutorial01/ they are creating an app called polls and a view inside, and when running the server the view is displayed. However, in the second tutorial https://docs.djangoproject.com/en/2.1/intro/tutorial02/ it is mentioned that the app should be added in the installed apps section of the settings.py To include the app in our project, we need to add a reference to its configuration class in the INSTALLED_APPS setting. The PollsConfig class is in the polls/apps.py file, so its dotted path is 'polls.apps.PollsConfig'. Edit the mysite/settings.py file and add that dotted path to the INSTALLED_APPS setting. I am not sure how it worked in the first tutorial without including the app. Isn't it mandatory to include the app? or is it mandatory only in specific use cases? Thank you -
