Django - 'User' object is not iterable
When i am passing instance1 in context it giving error 'User' object is not iterable. I want to display Name in Template of pk.

Changing error messages in django-rest-auth
Whenever I make a POST request with an empty username value, I get the following error message: "username": [ "This field may not be blank." ], I'd like to change this error message to my own custom error message. However, in my User model I try to create a blank error message like so: class User(AbstractBaseUser): username = models.CharField(max_length=15, unique=True, error_messages={ 'blank': 'You have to have a username!', 'unique': "Username has already been taken.", }) However, this error message does not show, instead the default error message shows. How can I show my own custom error message? The unique error message shows up fine, it's just the blank one doesn't show up. -

Unable to view content in DetailView Django
I am trying to view the content in my blog posts using django DetailView class but when I run the local server and click on the headline link in my blog post, while the url bar changes to read the correct post, the actual page stays the same, and so I can't view individual blog posts.

id(number) path in urls

I tried to create a page with urls: localhost:8000/topics/1/ urlpatterns = [ path('topics/(?P<topic_id>\d+)/', views.topic, name='topic'), ] In views.py.

How to limit fields returned in django queryset per field
I have rows of products, that tend to share some information, such as the same images (an image may show multiple products), descriptions, manufacturer, etc. I would like to choose some fields to only show the information once. I can't use distinct for this (I don't think) as the information is not always identicle, such as with the description, but may be only subtly different enough that I don't want to repeat it. At the moment, I am using a for loop to display fields from each result, which ends up with something like this: This is the code I am using in my view: def collection_detail(request, name=None): template = loader.get_template('/webapps/mywebapp/furniture/main_page/templates/main_page/detail.html') products = product.objects.filter(id=name) cart_product_form = CartAddProductForm() context={'products': products, 'cart_product_form': cart_product_form} return HttpResponse(template.render(context)) What would be the appropriate way to do this in a view, ignoring subsequent rows for some fields? -

Security: bypassing login with URL entry
I’m looking to create a login system for my Django web application with is connected to a MySQL database with a table for managers that holds their name, email, and password. My login screen has a URL of localhost/login. I want to query the off-server database for the username and password for each manager that was entered when the user puts in the information. If the credentials match, then I want to redirect them to the manager page, which is localhost/manager. If they don’t match, then I want to keep them at that page, localhost/login. My question is what’s stopping the user from inputting the localhost/manager URL path into their browser and bypassing the login, getting access without getting authenticated? Is there a good way to store the user name and password in the database to make them more secure but also accessible and checkable again? -

Display thumbnail from image without creating or modifying file, based off of url?
I have a database with rows, with one of the fields being image_url. The images specified by these urls are high resolution and have different aspect ratios. I need to use some of these images to display thumbnails. I am thinking of running them through an image program to automatically create thumbnails, and then add a new image_thumbnail_url field of the like. Alternatively, I have seen some software which leads me to believe it may be possible for django to take these images, resize them in memory and then serve them to the client, without having to create new resize images. Is such a method possible, and if it is possible, is it efficient, or frowned upon? -
How to have a local instance or React hit a local instance of Django
I have a django api (djangorestframekwork, django2.1, python 3.6) that I run locally - http://127.0.0.1:8000/api/cards/b361d7e2-6873-4890-8f87-702d9c89c5ad. This api seems to work well. I can hit it via the web api or use curl/requests to add to or view the database. Now, I want to be able to have my React project hit this api. I can have my react project hit a different api and it returns the data, but when I replace that URI with my own URI it breaks. App.js - there is one line commented out. Switch that out with the other to switch between the public and private api. import React from 'react' import keyforge from '../api/keyforge' import localhost from '../api/localhost' import SearchBar from './SearchBar' class App extends React.Component { onSearchSubmit = async (term) => { const response = await localhost.get("api/cards/" + term) //const response = await keyforge.get("api/decks/" + term) console.log(response) } render () { return (<div className='ui container'> <SearchBar onSubmit={this.onSearchSubmit} /> </div>) } } export default App keyforge.js - this one works! import axios from 'axios' const proxyurl = 'https://cors-anywhere.herokuapp.com/' const url = 'https://www.keyforgegame.com/' export default axios.create({ // baseURL: 'https://www.keyforgegame.com/api/decks/' baseURL: proxyurl + url }) localhost.js - this one does not work import axios from 'axios' … -
Accessing dictionaries given django template's attributes?
So my problem is that I need to iterate over a dictionary given an attribute, which is the value of the for loop. For example, I have a dictionary called my_dictionary which is being iterated by a for loop in a django template, with an attribute called q. What I need is to access to that dictionary by using the q attribute. I tried with {{my_dictionary.q}}, {{my_dictionary.{{q}} }} but none of them did work. What can I do? I guess it should be similar as in Python my_dictionary[q]. Thank you. -
User Profile 'Syntax Erro'r in Django
I am trying to create the user profile in Django. t is a new User model that inherits from AbstractUser. It requires special care and to update some references through the settings.py.

What are dependancies and why should I care about them?
I am a beginner to web development, and am currently engaged in creating a Django web application to interface with a MySQL database. Through the time I've spent reading the documentation for Django, it constantly talks about isolating dependancies using virtual environments like virtualenv. I don't really understand what a dependency is and why creating a virtual environment would help 'isolate' them from each other. What is a virtual environment? Is it like another machine running on your machine? Any input for these conceptual questions would be much appreciated. -
WHY connect MySQL database to Django?
I am creating my first ever Django web application, which is essentially a portal for managers to view the current status of a MySQL database. I’m having trouble understanding why I should connect MySQL to Django instead of just writing Python scripts to connect directly to the database using the pymysql library. Plus, if I decide to go forward with connecting Django and MySQL, what would interfacing them look like? I'm currently hosting both the Django web app and the MySQL database on my computer, but will eventually host them on external servers. I'm a webdev beginner and any input would be much appreciated. -

Django PIL unexpected image rotation
I have a Django project with a model with ImageField fields, I use Pillow to manage images, but I find that Images are rotated and are always saved in portrait orientation, in despite of its original orientation. Is there any way to instruct PIL not to change image orientation, but to keep the original one?
