is it better to include token as a field in the User model for Django+SimpleJwt?
i'm looking at different ways of using django rest framework with jwt, and most cases would do it in a "normal" way (as the Getting started in the simple Jwt Documentation says), but i encoutred some ones that extends the User model and include the Token inside, something like : class User(AbstractBaseUser, PermissionsMixin): # .....(usual fields(username, password,...)) @property def token(self): return self._generate_jwt_token() def _generate_jwt_token(self): dt = datetime.now() + timedelta(days=60) token = jwt.encode({ 'id': self.pk, 'exp': int(dt.strftime('%s')) }, settings.SECRET_KEY, algorithm='HS256') return token is this way better? or is it just a different way to handle it? what difference does it make? -

how to filtering queryset in django template
I used a function in models.py to output the queryset result to the template. Now what I want to do is filter the output queryset back in views.py. Is it possible to filter with the code below?

How to store in a JavaScript variable the selected rows in a table
Let's say we have a table like this: <table> <thead> <tr> <th class="active"> <input type="checkbox" class="select-all checkbox" name="select-all" /> </th> <th>A</th> <th>B</th> </tr> </thead> <tbody> {% for gene_variant in gene_variant_results %} <tr> <td class="active"> <input id="selectedGene" type="checkbox" class="select-item checkbox" name="select-item"/> </td> <td>{{ gene_variant.67 }}</td> <td> {{ gene_variant.72 }}</td> </tr> {% endfor %} </tbody> </table> <button id="select-all" class="btn btn-primary">Select all</button> <button type="submit" id="show-selected" class="btn btn-primary">Show selected</button> And let's say that gene_variant_results has for example, 4 results. Each result corresponds to a row (each row has about 100 columns, in this example I only put 11 for illustrative purposes): (1290, 'chr10', '73498294', '73498294', 'C', 'G', 'exonic', 'CDH23', 'DM', 'CM127233', 'DFNB12) (1291, 'chr11', '73498295', '73498295', 'D', 'H', 'exonic', 'CDH24', 'DM', 'CM127234', 'DFNB13) (1292, 'chr12', '73498296', '73498296', 'E', 'I', 'exonic', 'CDH25', 'DM', 'CM127235', 'DFNB14) (1293, 'chr13', '73498297', '73498297', 'F', 'J', 'exonic', 'CDH26', 'DM', 'CM127236', 'DFNB15) For example, if I click on the first two checkboxes and then click on the #show-selected button, I would like to store in a JavaScript variable the values of those selected rows.

why Search function is not working in django?

Django and google_streetview API
Is there a way to retrieve a street view image from google_streetview API in Python/Django and pass it to templates without having to save the image within Django? I know you can create an API call using Javascript, although I am looking to see if there is a method to do the API call in the backend to avoid showing my API Key in the frontend or is this even necessary? I am not even sure what might be best practice for this. I am currently using Javascript to allow for the Google Places Autocomplete API. Is it secure enough to simply have restrictions in place on your API key's for which API your key is good for and a Application Restriction? Currently I have this in place from the google_streetview package: import google_streetview.api def streetview(coord): params = [{ 'size': '300x200', 'location': coord, 'fov': '100', 'key': settings.STREETVIEW_KEY }] results = google_streetview.api.results(params) However, the only things I know you can do with results is .preview(), .save_links(), .download_links(), .save_metadata(). -

in Django,what is the best way to store a content which consist of images and text?
I am building a website like a blog. On my website, I am going to have an article with at least 4 paragraphs and also a minimum of 4 pictures. I am planning to use RichTextField for it but I am here to get advice from you experienced people. As I said, I am totally new to Django. What is the best and fastest way to store an article with images? By the way, before I asked the question, I googled it but most questions came down to Django 2.0. There must be better ways now. Thank you all. -
Best way to handle LoginView login on all pages in Django
I am new to Django and I have spent a lot of time trying to find a solution to my problem but was not successful. I have a top navbar that is included in the base.html file and every page extends base.html. In my navbar, I have a button that shows a modal (bootstrap) and I want this modal to show the login form. My url.py is as follows: from django.urls import path, include from .views import RegisterView from django.contrib.auth.views import LoginView, LogoutView, PasswordResetView, PasswordResetDoneView, PasswordResetConfirmView, PasswordResetCompleteView, PasswordChangeView, PasswordChangeDoneView urlpatterns = [ # Mapping django auth at the root # The URLs provided by auth are: # login/ [name='login'] # logout/ [name='logout'] # password_change/ [name='password_change'] # password_change/done/ [name='password_change_done'] # password_reset/ [name='password_reset'] # password_reset/done/ [name='password_reset_done'] # reset/<uidb64>/<token>/ [name='password_reset_confirm'] # reset/done/ [name='password_reset_complete'] #path('', include('django.contrib.auth.urls')), path('password_reset/', PasswordResetView.as_view(), name='password_reset'), path('password_reset_done/', PasswordResetDoneView.as_view(), name='password_reset_done'), path('password_reset/<uidb64>/<token>/', PasswordResetConfirmView.as_view(), name='password_reset_confirm'), path('password_reset/complete/', PasswordResetCompleteView.as_view(), name='password_reset_complete'), path('password_change/', PasswordChangeView.as_view(), name='password_change'), path('password_change/complete/', PasswordChangeDoneView.as_view(), name='password_change_done'), path('login/', LoginView.as_view(), name='login'), path('logout/', LogoutView.as_view(), name='logout'), path('register/', RegisterView.as_view(), name='register'), ] As you can see above, path('login/', LoginView.as_view(), name='login'), will only correctly resolve {{ form }} in localhost:8000/login but I want it to resolve in all paths to achieve what I want.

How do I loop through two models to get attribute differences in a django template?
I am trying to figure out how to get the attribute differences from two different django models. They have common attributes, and I want to compare the common attributes to see the differences. I have managed to define both querysets with values and I can get the primary attribute fine. The problem is when I am trying to loop through both of the models and get the attribute values and compare them. I have done something like this... {% for i in books.all %} {% if i not in author.all %} {% if i.author_name %} Author Name :{{ i.author_name }}. {% endif %} {% endif %} {% endfor %} The above works. The problem I'm having is when I try to do something like... {% for i in books.all %} {% if i not in author.all %} Author Name :{{ i.author_name }}. {% endif %} {% for j in author.all %} {% if j.publishers.name != i.author_name %} Print Don't Match {% endif %} {% endif %} {% endfor %} I tried the above example and it doesn't produce output. I've confirmed the values are identical, but I can't seem to get the template to show me the attribute differences. I … -

Why do I keep getting Class ModelSerializer missing "Meta" attribute?
whenever I try to access the view for my registration serializer I keep getting that I'm missing the Meta attribute even though it's there.

Why do I keep getting a NoReverse Error in Django 3.2

So I am following the Django tutorial and I am getting this error. I am using the generic views in Django just like the tutorial did. Before using generic views everything was working.

Can't execute my functions out of the fetch function - JavaScript
it's my first JavaScript snippet. I run into the following problem. I'm trying to load serialized with Django Rest Framework data and then render the list of questions and the pagination bar. I also have likeQuestion, PaginationListener and SortingListener functions. In the snippet below I execute likeQuestion, PaginationListener and SortingListener functions within fetch function. It works but since it turns out to be recursive it results in multiple http-requests doubling with every click (actually only SortingListener function behaves this way, PaginationListener - surprisingly don't). I also tried to execute all the three functions out of the fetch function. It doesn't work: when I try to get the elements the html collection is zero length. I tried it with window.addEventListener('DOMContentLoaded', (e) => {}). Still doesn't work. Outside the fetch function it works only with setTimeout. But in this case the PaginationListener works only for the first click. And timeout seems to be not a very good decision. How should I change my code to make it work smoothly? const url = document.getElementById('question-list').dataset.url getQuestionList(url) // Ask.index page loading function getQuestionList(url) { const questionList = document.getElementById('question-list') fetch(url).then(response => response.json()).then(json => { // Questions List loading questionList.innerHTML = '' for(const question of json.results){ date … -
DJANGO for loop to show product images from thumbnails
I have a product detail page with images of the product. The number of images is not fixed, and the images are uploaded using a multi-upload function. This is all working correctly. I am now having problems getting the images to show and be selectable by the user from the thumbnail in the main produce viewer. The images show, but the user can not click on an image thumbnail to show that image in the viewer. The code works if the image locations are hardcoded and for that reason I have not included the javascript that changes the images.
