htmx and django : dependant select options
I am trying to develop an app in Django where I add partials, using HTMX, everything works properly except for one critical thing. In the form I am loading from the partial, there are 2 select options, that are dependant on each others, traditionally without HTMX, I use a simple Javascript to link them both <script> $("#id_data_form").live('change', function() { var url = $("#extractor_query_builder").attr("data-fields-url"); var dataformId = $(this).val(); $.ajax({ url: url, data: { 'data_form': dataformId }, success: function (data) { $("#id_data_fields").html(data).height(150); } }); }); </script> This works fine when I work without HTMX, but when I add the HTMX way of doing it, it seems like the javascript does not find the DOM corresponding to the form elements when the form is injected in the main document my form looks like this <div hx-target="this" hx-swap="outerHTML" class="mt-3 py-3 px-3 bg-white shadow border border-gray-100"> <form class="form-horizontal" id="extractor_query_builder" method="POST" data-fields-url="{% url 'getFields' %}" novalidate> {% csrf_token %} {{ form | crispy }} {% if extract %} <button type="submit" hx-post="{% url 'update-extract' extract.id %}"> Submit </button> <button hx-get="{% url 'detail-extract' extract.id %}" type="button"> Cancel </button> {% else %} <button type="submit" hx-post="."> Submit </button> {% endif %} </form> </div> but I noticed when I submit the … -

RestrictedPython: Call other functions within user-specified code?
Using Yuri Nudelman's code with the custom _import definition to specify modules to restrict serves as a good base but when calling functions within said user_code naturally due to having to whitelist everything is there any way to permit other user defined functions to be called? Open to other sandboxing solutions although Jupyter didn't seem straight-forward to embed within a web interface. from RestrictedPython import safe_builtins, compile_restricted from RestrictedPython.Eval import default_guarded_getitem def _import(name, globals=None, locals=None, fromlist=(), level=0): safe_modules = ["math"] if name in safe_modules: globals[name] = __import__(name, globals, locals, fromlist, level) else: raise Exception("Don't you even think about it {0}".format(name)) safe_builtins['__import__'] = _import # Must be a part of builtins def execute_user_code(user_code, user_func, *args, **kwargs): """ Executed user code in restricted env Args: user_code(str) - String containing the unsafe code user_func(str) - Function inside user_code to execute and return value *args, **kwargs - arguments passed to the user function Return: Return value of the user_func """ def _apply(f, *a, **kw): return f(*a, **kw) try: # This is the variables we allow user code to see. @result will contain return value. restricted_locals = { "result": None, "args": args, "kwargs": kwargs, } # If you want the user to be able to … -

handle a request in django that takes a long time to process is a lambda function and api gateway better? OR async django function
I have a function in my django rest framework api that I am working out. I suspect that it will take a long time to finish. About a minute. Given api requests expect a response I suspect this is a problem. My initial thought was set up a aws lambda function that is tied to a aws api gateway, secured by a api key. The idea being that the front end calls the api gateway url, and the url and the api key are sent over by my server only when the user who requests the url and apikey has access. But is this secure enough? Or is it better to have a django function that runs async? Meaning run the work that needs to be done async and immediately return the 200 response? Then just have another endpoint that polls the server to see if the work has been done? Can the async behavior even be done in the way I describe? https://docs.djangoproject.com/en/4.0/topics/async/ after reading the docs it doesn't seem to do what i expect it to. I guess we can't return 200 while the function works. So AWS amazon gateway seems to be the win. But I worry … -
How is the file from OneToOne Model's FileField accessed, read in views.py and passed to template?
I am developing a simple Data Visualization App, where a user can register, login upload a file and visualize its content. I am using default User model, and a Detail Model having OneToOne relation with User Model. The Detail has 3 fields, which are: OneToOne(User) FileField() TextField() Now, I want to access the file that is saved in FileField, in views.pyand read it's content, then visualize it using Python'sNumPyandMatplotlib`, then finally show visualization results on the frontend. I need a guidance that how should I start and approach this task? Basically, I need deep guidance in how to access and read the file in views.py?

Implementing a search query inside a filter
I've been trying to implement a search bar inside my application, but I don't know how to query for similar names inside my db. Here is my view.py queryprms = request.GET name = queryprms.get('name') status = queryprms.get('status') if name: moderatorRoom = PokerRoom.objects.values("id", "first_name_user", "date", "name", "status", "styleCards", "datetime", 'slug' ).filter(Q(user=user), Q(name=name)).order_by("-datetime") The problem is that when the user search for a similar word, say "Alch" for "Alchemy", the query returns empty even if "Alchemy" object exist inside my db. I want that the query returns similar objects for the user's search. How can I do that? By the way, I'm using Postgre and Django 3.1.5. -

Django models: which field to use for position/order of an object
My project is a basic scrum board with a model Column, of which there can be unlimited instances. Each column is displayed side by side, and I want the order of the columns to be customizable. My thought was to use an IntegerField to determine numerical position, but I'm struggling with how to set the max_value equal to the total number of columns since it varies by board. Here's how I set it up: class Column(models.Model): name = models.CharField(max_length=25) board = models.ForeignKey(Board, on_delete=models.CASCADE) position = models.IntegerField(unique=True,min_value=1, max_value=???) My problem was what to use as the max_value. I tried solving it by doing this: class Column(models.Model): max_value = Column.objects.get(board=board).count() name = models.CharField(max_length=25) position = models.IntegerField(unique=True,min_value=1, max_value=max_value) I know this obviously won't work. Could I somehow use class Meta to set constraints instead, or what would be a good way to approach this? -
