Update a Model in Django right before the backend select
Before my Model in Django gets hydrated and filled with data, I want to update (alter) my model, save it back to the database and then go on the normal way. My approach (not working) as now is this: from django.db import models from MyApp import models as m class CustomManager(models.Manager): def get_queryset(self): # This is not evaluated to true although it should from my assumption: if (isinstance(self.model, m.MyObject)): # Here I want to take the internal key of # MyObject (maybe from the URL?), # Simply accessing self.model.internal_key does not work. # Then make an API call to an external server, # update my local object, save it back to db and proceed print(self.model) # Prints <class 'MyApp.models.MyObject'> Can someone point me to the right direction if this is the correct approach and how I go on? -

Django's get_initial() method not working as desired
I am using django's generic CreateView to build a comment system for my site. A user is allowed to do comment for a movie.

Django REST throwing [Errno 54] Connection reset by peer and Bad Request
I am using Django REST API for my server in combination with Djoser library for authentication. The client part is written with Vue.js, and I use Axios for API requests. Now I am trying to make the server and client parts interact. I have started with authentication. My server is up on 127.0.0.1:8000. When I use Postman to request an authentication token based on username and password, I send a POST request and get a response: Then, I am trying to reproduce such a request using Vue and Axios. I have defined a component named Login and written the following there: <script> import axios from 'axios' export default { name: "Login", data() { return { login: '', password: '' } }, methods: { setLogin() { axios({ method: 'post', url: 'http://127.0.0.1:8000/auth/token/create/', body: {username: this.login, password: this.password} }) .then(function (response) { sessionStorage.setItem("auth_token", response.data.attributes.auth_token) }) .catch(function (error) { console.log(error); }); } } } And the template consists of just 2 inputs (for login and password) with v-model=login and v-model=password and a button with @click="setLogin".

Error 404 not found raises 500 when Debug set to False
I recently tried to implement a custom view for my 404 and 500 errors on my website. It works well when debug is set to True, i.e. both the custom views work well when called.

How to add custom HTML elements and images to a blog in Django?
I am trying to create a blog in Django. Most of the tutorials and examples available shows just retrieving some content from the database and displaying it dynamically on the predefined HTML structure. After looking at some solution I found something called flatpages in Django which provide the facility to write HTML. But its recommended to use it for About Us and Contact Us kind of pages. Should I use this? I want to do it as I can write my own HTML data for each blog and add some images so that the structure of HTML should not be similar in each blog. For example, In the case of WordPress, it allows the user to completely write each part of the blog except the heading part and the structure of HTML is not constant always. I want such functionality. Please help. -
