Block evaluation of template tags but not variables
I am using Django's template engine to evaluate user-supplied template strings. I would like to allow the users to use the variable mapping functionality, but not the tags or filters. For example: from django.template import Context, Template user_template_string = "V1: {{ var1 }}. V2: {{ var2|truncatechars:5 }}. {% if var3 %} yes {% else %} no {% endif %}" template = Template(user_template_string) context = {'var1': 'One', 'var2': '123456789', 'var3': True} output = template.render(context=Context(context)) # Desired output: # "V1: One. V2: 123456789. {% if var3 %} yes {% else %} no {% endif %}" Is there a way to configure the template engine to render variables but ignore tags and filters? Or is my best bet to sanitize the user input and try to strip out all tags and filters that they may include? -

How to filter the amount of options which the user can choose depending on the previous selected option (DJANGO)
I have been trying for a while to implement a filter system in which it changes the options that the user can select depending on the previous option chosen in my DJANGO application. The process is like that :[The user will select a school][then depending the school that the user has chosen just the courses this school has will be displayed] [then after selecting the course the only options the user will have are the ones that are related to School -> Course - > Classes - > Semester then all the books with the exactly matching metadata will be displayed. Does someone can guide me or give some ideas on how I can implement that ? I have tried many to many and one to many relationships already but I was not successful :/ Also for real time changes will I have to implement AJAX with the application for that ? Thank you for your time :) Here is a image to show how the application will look like: https://i.stack.imgur.com/xympT.png -

Heroku not updating static files for Django webapp
I noticed that recently my static files on my Django web app are not being updated on my website despite being successfully pushed to Heroku master, and working fine locally. Now I have tried several steps: I first got my git status and it says Everything up to date. My DNS Host is CloudFare so I have done Purge Cache and still nothing. I have also triied heroku repo:purge_cache -a appname to delete my cache and then ran an empty commit and still nothing. I have deleted my browser cache several times and still, my static files are not being updated despite me running python manage.py collectstatic and heroku run python manage.py collectstatc and committed, yet nothing. Now is there anything that I have missed? I do not know any other method to update my static files. -

How to call user variables in Django ModelAdmin
I am new to Django and having trouble understanding how to call proper variables in a ModelAdmin. If I am on /admin/mt_app/my_model/ that I have information like the user's name OR I'm on /admin/auth/user/2/change/ that has all the user's information, how do I call those variables in the ModelAdmin View? I got it working selectively by plugging in my own user, but I can't figure out how to call the relevant user or model from the view. All I can find is how to call the current user, but again, I need the user of the that the page is regarding, not the active user. Ex: /admin/algorx/pt_data/41/change/ or /admin/auth/user/2/change/ What I have now is: Admin.py class pt_dataAdmin(admin.ModelAdmin): fieldsets = ( . . . ) # This gets passed into change_view as extra context def get_dynamic_info(self): user = User.objects.get(email='MYSUPERUSEREMAIL') return user . . . def change_view(self, request, object_id, form_url='', extra_context=None): . . . So what works is passing in my super user's email to select that user: user = User.objects.get(email='MYSUPERUSEREMAIL') return user But what I want to do is select the user of the current page being viewed. If I'm on the following URL how do I select that user's variable? … -
Django TestCase to validate a ModelForm over multiple Models
I have flexible data models representing network switches and their individual ports that look similar to below (with apologies for the name of the first; unfortunate but I could think of no better): class Model(models.Model): name = models.CharField(max_length=20, unique=True) port_count = models.IntegerField() ... class Switch(models.Model): model = models.ForeignKey(Model, on_delete=models.CASCADE) name = models.CharField(max_length=14, unique=True) ... class Port(models.Model): switch = models.ForeignKey(Switch, on_delete=models.CASCADE) number = models.IntegerField() ... Data entry is validated to ensure Port.number is within the range of 1 to Model.port_count. This was a trivial TestCase to author. Another important validation is for my ModelAdminForm.clean() to ensure that reducing Model.port_count would not make any existing Port records violate the new range. (Those ports would likely need to be deleted first.) Authoring this clean() method was also trivial, but authoring a TestCase for this validation has landed me in new territory without a map or guide. Since such a test requires a bit of initial DB population, I created a helper: def add_one(cls, **kwargs): _log.info(f'adding one {cls.__name__}') return cls.objects.create(**kwargs) I started by developing the TestCase to mimic an edit of Model.port_count that would not have any issues, to prove my transactional parts correct. Later, I would extend the code so that there would … -
How to select an instance of a model from a queryset django?
I am creating a project for hosting cricket tournaments. I have created 3 apps in it: home, tournament and team. After adding a tournament, when entering the tournament's detail view, I can add a team to the tournament. My Team model has a ForeignKey to my Tournament model, and my Tournament model has a ForeignKey to my User model(built-in django user model). When creating a team, I want to save the team for a particular tournament. I don't understand how to access the exact tournament and save the team for that tournament only. My tournament detail html: {% extends 'menu.html' %} {% block content %} <div class="row"> <div class="col-8"> <table class="table table-bordered table-hover"> <tr> <th scope="col">Match between</th> <th scope="col">Winner</th> </tr> {% for match in match_list %} <tr> <td> {{ match.team1.name }} vs {{ match.team2.name }} </td> <td> {% if match.winner %} {{ match.winner.name }} {% else %} TBD {% endif %} </td> </tr> {% endfor %} </table> </div> <div class="col-4"> {% if teamscount < tournament.no_of_teams %} <button class="btn btn-primary" onclick="window.location.href='{% url 'teams:addteam' %}'">Add Team</button> {% endif %} </div> </div> {% endblock content %} My urls.py file in tournament app: from django.urls import path, include from . import views app_name='tournaments' urlpatterns … -
serializer field with "allow_null" automatically sets value to null
I have the following serializer class NiceSerializer(serializers.Serializer): nice_field = serializers.CharField(required=False, allow_null=True) another_field = serializers.IntegerField(required=False) I need the nice_field to be nullable, that's why I put allow_null=True, however, sometimes I make a patch request that should only update the value of another_field, so the request does not contain the nice_field value. The problem is that the after validating the request data the NiceSerializer automatically set the value to None, which is a very inconvenient behaviour. How can I write a serializer where I can eventually ignore a field in the patch request? Thanks a lot -
How to pass values of a dropdown list from html to python using django

How to convert bytes to a string of the same length in Python (1 character for each byte)?
I need a random string that I can write down to use for salt in a hash function. I can generate some random bytes and see them as hex: import os, binascii print(binascii.b2a_hex(os.urandom(32))) b'76449cd6134d64353122102fcb512d1eae1bd8437202b6e06e91a422ce9e386b' # 64 chars Great, but how do I convert these bytes directly to a string i.e. not necessarily printable, but exactly 32 characters? The hash function requires a string, not a "bytes" type with a maximum length of 32. I'm not sure how to do the encoding in Python, but I guess I need something similar to the way an old 8-bit computer or a C program would turn a byte into a character (ASCII or other). This is for the salt input of Django's make_password function. -

No revision info error when running manage.py in Django
I am currently working on a Django project and have run into the follow error whenever I run any of my manage.py commands: Revision invalid: Got "no revision info! Check GIT_DIR=/Users/brockherion/dev." The issue seems to have come out of nowhere as I was able to add projects to my Django app without it. I can still run all the manage.py commands, but everyone of them throw this error. I have tried a couple of things, including: Removing PIP packages (I though django-markdownx was the cause, but it still throws the error without it) Removing my local git repo and creating a new one Checking out a new GIT branch Creating a new Django project (Works for a few commands then starts throwing it again) Merging all my branches so they are up to date I can still run my Django app. This just more of an annoyance than anything else. Again, it ONLY happens when I run manage.py, so I'm not sure if it's a GIT or Django issue. -

[OrderedDict([('name', 'technlogy')])] I know i can put it in a for loop and subscript it using i["name"]...but it only gives me the name property. I want the unique id to add in that many to many field in case there are lot of category objects having the name = technology my serializers.py file--> class CategorySerilizer(serializers.ModelSerializer): class Meta: model = models.Category fields = ['id', 'name'] class PostSerializer(serializers.ModelSerializer): categories_assigned = CategorySerilizer(many = True) class Meta: model = models.Post fields = ['id', 'title', 'body', 'categories_assigned'] def create(self, validated_data): post = models.Post.objects.create(title = validated_data["title"], body = validated_data["body"]) print(validated_data["categories_assigned"]) for i in validated_data["categories_assigned"]: print(i["name"]) // 'technlogy' return … -
Django, URL dispatcher not working when using angle brackets to capture a value
core/settings.py INSTALLED_APPS = [ ...

(django) .update() not working inside class model
I have the following code but the .update() in remove_user_invite() isn't working, and no errors are being thrown. Does anyone know what's wrong or how I can fix this? Many Thanks! models.py class StaffProfile(Profile): user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, db_index=True, related_name="staff_profiles", on_delete=models.SET_NULL) objects = CustomStaffProfileManager() def remove_user_invite(self): invites = StaffUserInvite.objects.filter(staff_profile=self, used_at=None, expires_at__gt=timezone.now()) invites.update(expires_at=timezone.now()) -
Client-side and server-side rendering of HTML page in a Django single page app
this question could be a duplicate but I have a specific use case. The app is a single page Django app. The user can choose from several options in a drop-down box. Depending on the choice, a few input boxes will need to be rendered. As an example, if the user chooses to order a pizza, the options in another drop-down menu should be related to the toppings whereas an order for drinks should provide options related to the type or brands. The resulting number of input boxes could be 5 with one option or 10 with a different option. I can think of rendering the page using JS or by using Python in the back-end. Because this app will be a commercial one, I do not need SEO as users need to log into the app first. I also want to minimize the amount of code that a competitor can 're-use' from my work. Will client-side rendering open up security problems? If not, is client-side the better way to go?
