Is there a way to duplicate a <details> tag containing a Django Form in HTML5?
I am making an application that accepts a list of family members wherein the head of the family can register every single member. For every member entry, there is a form that accepts their name, age, etc. Then, there is an Add Member option that would just duplicate the form. I figured out a way to duplicate the forms, but the app looks too messy when there are many form duplicates, so I used the details tag to give the user the option to hide other form duplicates to make it look cleaner. Here's a part of my html code: {% extends "registrationForm.html" %} {% load static %} {% block content %} {{ formset.management_form }} <details open> <summary>Member 1</summary> <div id="form_set"> {% for form in formset.forms %} {{form.non_field_errors}} {{form.errors}} <table class='no_error'> {{ form }} </table> {% endfor %} </div> </details> <input type="button" value="Add Member" id="add_more"> <div id="empty_form" style="display:none"> <table class='no_error'> <details open> {{ formset.empty_form }} </details> </table> </div> {% endblock %} What happens in my approach is, every time I click Add Member, it duplicates the form but it is not inside the details tag, and also the new empty form is also inside the first details tag which is … -
is there a way to define a customized method inside a Django class based view to handle requests at a specific URL?
What I have for now? in the urls.py file, I defined: path('groups', views.GroupView.as_view(), name="group"), I have a GroupView class to handle requests at /groups endpoint in view.py file, inside of which there are some methods to handle HTTP requests: class GroupView(APIView): def get(self,request) def post(self, request) def patch(self, request) What I'm trying to do: having a method to only deal with patch requests and only accept requests at 'groups/join' URL. I'm wondering if it's possible to define another customized method just inside the current class based view to implement this (instead of having another standalone function based view), I'm expecting something like: class GroupView(APIView): def get(self,request) def post(self, request) def patch(self, request) **def patch_join(self, request, url='/join')** Is this possible in Django? Thanks! -
Python update fields with matching name
I have three (or more in the future) integer fields with similar names: class Statistic(models.Model): first_count = models.IntegerField(default=0) second_count = models.IntegerField(default=0) third_count = models.IntegerField(default=0) I get a variable that tells me which one to update. If variable == "first" increment first_count, if variable == "second" then increment second_count... I am wondering, if there is a better way to do this? To paint you a better picture, this is what i would want to do: Statistic.variable+"_count" = Statistic.variable+"_count" + 1 #increment value But i do realize, that this wouldnt work and would also be a very bad practice. Is there a simpler solution I am not seeing? Thanks in advance -
mod_rewrite + django causing incorrect redirect URLs post login
I have a Django project with an app named "Survey" - it is desired that URLs such as http://example.com/Surveys/ViewInspection/1 are accessible via http://example.com/Inspections/ViewInspection/1. Using Apache 2.4 and mod_rewrite, I have the following set of rules in place to allow this: RewriteEngine On RewriteRule ^/Inspections(.+)$ /Surveys$1 [PT] and all appears to work fine, except where a non-authenticated user attempts to access the above URL (the view for which has the @login_required decorator. At this point, the user is bounced to the login screen with parameters: /Auth/Login?next=/Ins/Surveys/ViewInspection/1 After a bit of digging, "/Ins/Surveys/ViewInspection/1" is the value for request.path, whereas request.path_info is correctly set as /Surveys/ViewInspection/1 - the Auth code is taking .path and getting it wrong. If I use a shorter string than "Inspections" the Ins part decreases until disappearing, when it all works fine. mod_rewrite logs look correct in this instance: [Tue Feb 23 23:52:49.617840 2021] [rewrite:trace2] [pid 2760:tid 140156097316608] mod_rewrite.c(483): [client 213.18.147.204:4054] 213.18.147.204 - - [hostname/sid#7f78a4651338][rid#7f78a53910a0/initial] init rewrite engine with requested uri /Inspections/ViewInspection/2 [Tue Feb 23 23:52:49.617906 2021] [rewrite:trace3] [pid 2760:tid 140156097316608] mod_rewrite.c(483): [client 213.18.147.204:4054] 213.18.147.204 - - [hostname/sid#7f78a4651338][rid#7f78a53910a0/initial] applying pattern '^/Inspections(.+)$' to uri '/Inspections/ViewInspection/2' [Tue Feb 23 23:52:49.617940 2021] [rewrite:trace2] [pid 2760:tid 140156097316608] mod_rewrite.c(483): [client 213.18.147.204:4054] 213.18.147.204 - - … -

Custom AutoField Integer Sequence in Django
I have Django with default IDs, and I want to distribute the system without use of random UUIDs. I take that in my use case, the number of servers won't exceed a N=1000, so, I'd like to reserve IDs sub-sequences to each server, so that: SERVER 1 would have IDs 1001, 2001, 3001,... SERVER 2 would have IDs 1002, 2002, 3002, etc. I'd like to do that globally, including all models, even Django system models, so I've defined a function to get the last ID of the subsequence, like: # Used to split primary key spaces. SERVER_ID = int(os.getenv('SERVER_ID', 1)) # Function to compute different next primary key for each server: def DB_NEXT_PK(Model): ID_LENGTH = 3 FACTOR_10 = 10**ID_LENGTH last = Model.objects.filter(id__endswith=f'%.{ID_LENGTH}d' % SERVER_ID).last() if last is not None: return ((last.pk // FACTOR_10) + 1) * FACTOR_10 + SERVER_ID else: return FACTOR_10 + SERVER_ID So, suppose I want to use such or equivalent function for the IDs. How would I have to override the django.db.fields.AutoField to properly do this? I found the latest Django 3.2, here has an option to customize AutoField, but I don't quite get how it is best to do to accomplish this. I'm currently looking into … -

tweaking LoginRequiredMixin django
I have a custom user model extending Abstract User. There is another model storing the user types. There are two types of users: clients(id is 1) and Professional(id is 2). I am trying to restrict the professionals from seeing a few links. These links are classified to the clients only. I am trying to tweak the LoginRequiredMixin and use it in my views.

invalid hook call on data retrieved by axios
I'm trying to retrieve the JSON data from here and then update the state in a functional component. Even though the code seems fine I'm getting an error saying its an invalid hook call. On the react documentation it said that I might have 2 different react apps in the same folder however I checked it with the command they gave and there was only 1. However I am running this from a django server and there is a different react app in a different django app (so in a completely different folder). const App = () => { const [posts, setPosts] = useState([]); useEffect(() => { let url = "https://jsonplaceholder.typicode.com/posts"; axios.get(url).then(res => { console.log(res.data); // The code crashes here saying that it is an invalid hook call useState(res.data); }).catch(err => console.log(err)); }, []); return ( <div> This is just a place holder. </div> ); } I have a feeling this might have something to do with the other react application in the django project but if anyone can see something that I can't I would appreciate the help. -
Django 3: is_valid() is always false using FileField and FloatField
I am trying to make a simple form in Django that accepts some file upload fields and a few float fields. However, when I run this in my browser, the is_valid() never gets triggered even when all forms are filled in. I have looked through the Django docs and have tried to recreate the examples as much as possible, but I can't figure out what is wrong.

Django console gives 401 unautorized async function testSizze(){ const res = await fetch("http://127.0.0.1:8080/api/editor/project/1/copy/", { method: "POST", headers: { "Content-Type": "application/json", "Authorization": "Token 8fdc5648e07851c9ebe3c05f56b4c2400f2d90b9" }, body: JSON.stringify({ "to_user": "admin@mail.ru", "permission": ["read"], "all_users": "False" }) }); const json = await res.json(); console.log(json) }
