localStorage.getItem return string, how to get an array and loop through it, also how to compare against existing data if the data id still there?
I have a page lists ads. each ad has a favorite icon. user can click on icon for every single ad to add it to the favorite list. The favorite list is stored on local storage(using cookies). I have made everything. the code works fine ( store selected data). I wrote a code to pull stored favorite ads once the page is loaded. I want to populate the favorite icons with previously favorited ads(data obtained from local storage). The icons has class (fa-star-o) while favorite icons should have class(fa-star). Hence, I need the following Two tasks: 1- I want to find the ads IDs stored on the local storage. Then loop through them and change the icons class based on them. 2- I want to compare existing IDs with current IDs come from the data base because every ads expires after 45 days and will be removed from the data base. How can I do that? The existing problem is the data came from local storage return as string. I did made the following code to make it an array: var stored_fav = JSON.parse("["+localStorage.getItem('SL_favourites')+"]"); The result is an array. However,when I loop through this array, I expect to have all … -
Django Infinite scroll using Django Paginate repeating the queryset
Intro: I am using the the below link to add infinite scroll to my project https://simpleisbetterthancomplex.com/tutorial/2017/03/13/how-to-create-infinite-scroll-with-django.html below is the github code for that link https://github.com/sibtc/simple-infinite-scroll The link shows how to add infinite scroll to both function based views and class based views. I have added this to my function based view and it works perfect. The problem: I have 8 posts in my post-list which is a class-based view. After I add paginate_by = 3 I can only see 3 posts of the 8 posts. Everytime I scroll down these 3 posts keep repeating in an infinite loop My Views: class Postlist(SelectRelatedMixin, ListView): model = Post select_related = ('user', 'group') paginate_by = 3 context_object_name = 'post_list' template_name = 'posts/post_list.html' My Base.html: (I have the below files in JS folder they worked for my FBV) <script src="{% static 'js/jquery-3.1.1.min.js' %}"></script> <script src="{% static 'js/jquery.waypoints.min.js' %}"></script> <script src="{% static 'js/infinite.min.js' %}"></script> {% block javascript %}{% endblock %} My post_list.html: <div class="col-md-8"> <div class="infinite-container"> {% for post in post_list %} <div class="infinite-item"> {% include "posts/_post.html" %} <!---This code is good----> </div> {% empty %} some code {% endfor %} </div> <div class="loading" style="display: none;"> Loading... </div> {% if page_obj.has_next %} <a class="infinite-more-link" href="?page={{ … -

Does Django's csrf_exempt decorator remove all POST data?
I have a Django view which returns a list of objects, or allows you to create one if you POST... @csrf_exempt def quantities(request): if request.method == "POST": kwargs = {**request.POST} print(request.POST) quantity = Quantity.objects.create(**kwargs) return JsonResponse({"quantity": f"/quantities/{quantity.id}/"}) return JsonResponse([], safe=False) If it gets a GET request it returns a list of quantities (code not shown), which works fine, and if it gets a POST request it uses POST data to create a new quantity. (I'm aware DRF does all this for you, but for my first API I wanted to try doing it manually - you just understand it better that way.) Anyway in my test, I use requests to check this works... response = requests.post( self.live_server_url + f"/quantities/", data={ "name": "Height", "units": "m", "description": "Human Height" } ) This doesn't work - it doesn't pass any data. That print statement in the view above just prints <QueryDict: {}>. For some reason the POST data that I put in the request has gone from the request by the time it passes through all the middleware and gets to the view. The only thing I can think of is that the @csrf_exempt decorator is removing POST data, though I can't imagine … -

Example of how to Subclass Column() in Django-tables2
Can anyone point me to an example of how to subclass the base Column() in django-tables2 please. By default the django-tables2 base Column() attrs supports 'th', 'td', 'cell' and 'a' as detailed in the documentation, which also states that this can be extended by subclasses to allow arbitrary HTML attributes to be added to the output. What I want to try and do, which may be either ambitious or flat out stupid and wrong, is to add a 'ul' attribute (and subsequently 'li' attributes) so that I can render a dropdown menu in a cell. My thinking is to have an options button on each row of my table that provides the user with the various options of 'delete', 'copy', 'archive' etc via a css or js dropdown menu. -

Why do we have to include staff and admin fields in custom user django model?
Let's say I am building a social networking website that has nothing do with admin and superuser. But I still have to include these fields while making custom user model. This is going to be a simple model that has user's profile information not that user is admin or superuser. Can anyone explain why do we always need these fields to be there. Can we get rid of them and still create a Custom user model or do we always need them. -

How to add link to npm package to a django template using the script tag when path is always converted to a url
I am trying to add a link to a folder in the npm_modules folder located in the root of my Django project to one of my templates. However, when attempting to do so, the path typed in is simply appended to the current url and is treated as a link. Since my folder is not there, it is not loaded and my javascript crashes. Since it is best practice to keep the npm_modules folder in root, how do I go about referencing folders within it inside my templates? <script src="\node_modules\angular-file-upload\dist\angular-file- upload.min.js" type="text/javascript"></script> -
How to save extra fields on registration using custom user model in DRF + django-rest-auth
Using Django REST Framework (DRF), with django-rest-auth, I created a custom user model with one extra field. My aim is to use the django-rest-auth registration endpoint to register a new user in one request, and thus sending all the data to create a new user, including the data for the extra field. I am using AbstractUser, since it seems recommended for beginners, where more advanced developers could use AbstractBaseUser. This is also why the following SO answers looks too complicated for what I want to achieve: link here. I know this question has been asked multiple times, but the answers are not exactly what I am looking for. For a beginner like me this is complicated stuff.

Django dict key,value in for loop does not work
I'm getting a little stuck on a Django problem where I can't access the values of a dict in a for loop. It works outside the for loop, just not inside. Am I missing the obvious here? Python: err{} err['else'] = {'class': 'Low', 'txt': 'zero'} err['if'] = {'class': 'High', 'txt': 'one'} data = { 'errors': err } return render(request, 'index/error.html', data) HTML template: <p>{{ errors }}</p> <p>{{ errors.if }}</p> <p>{{ errors.if.class }}</p> {% for error in errors %} <div class="{{ error.class }}"><p>{{ error.txt }}</p></div> {% endfor %} The upper 3 lines are for code debugging and work just fine. The for loop doesn't produce any code. Best regards, LVX -

Multiple left join and left join against the same model raw query convert to Django ORM
Using Django 1.11 I have the following models: class Product(Model): class Pricebook(Model): class Quote(Model): class SKU(Model): product = models.ForeignKey(Product) pricebook = models.ForeignKey(Pricebook) class SKUPrice(Model): sku = models.ForeignKey(SKU, related_name="prices") class LineItem(Model): quote = models.ForeignKey(Quote, related_name="quote_line_items") sku = models.ForeignKey(SKU) This is the raw query that works for me. SELECT qli.quantity, sku_source.product_id, sku_dest.id as sku_dest_id, sku_dest_price.id as sku_dest_price_id FROM lineitem qli INNER JOIN sku sku_source ON qli.sku_id = sku_source.id LEFT JOIN sku sku_dest ON sku_dest.pricebook_id = sku_source.pricebook_id AND sku_dest.product_id = sku_source.product_id LEFT JOIN skuprice sku_dest_price ON sku_dest_price.status = 'default' AND sku_dest_price.sku_id = sku_dest.id WHERE qli.quotation_id = 40 AND qli.quantity > 0 AND sku_dest.vendor_id = 38; What I have tried is: the_quote_with_id_as_40.quotation_line_items.filter(quantity__gt=0).select_related('sku__product').values('sku__product__id', 'quantity'); This produces this query SELECT "sku"."product_id", "lineitem"."quantity" FROM "lineitem" INNER JOIN "sku" ON ("lineitem"."sku_id" = "sku"."id") WHERE ("lineitem"."quotation_id" = 40 AND "lineitem"."quantity" > 0) which is not exactly what I want. I can of course use raw query. But I would like to know if possible to use ORM. At the very least, of expanding my knowledge. Thank you. -

How to create the manytomany "Through" object automatically?

The detail view of Article has "Add Section" and the section form works for adding a new section.

Don't use `get_queryset()` while creating
Let's say you are modifying get_queryset in you manager something like this class VoteManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(is_deleted=False) class Vote(models.Model): objects = VoteManager() This works as expected but the problem when you use something like get_or_create on Vote model it creates an instance even if it is present in the database because we modified the get_queryset() method. Can we not shadow the soft-deleted instance while creating?? -
