Django working with query parameters in raw Postgres queries
I use the `amount = (request.GET.get('page'))` and then i convert it into a int `amount= (int)amount` but when i tried to run this query: `cursor.execute('SELECT column1, FROM table LIMIT amount')` I get a error: `column "amount" does not exist` So is the any way how i can get the value to the query? -
I can't understand how to use correct static in django
I'm trying to display a picture whose address is saved in the Django models attribute. As I know you need to enter in the fieldurl({% static movie.img %}) but it doesen't works. If only use url({% static 'img/default-movie.png' %}) it works. That is my query sets from django shell: In [21]: Movie.objects.first().img Out[21]: <ImageFieldFile: ../MovieApp/movies/static/img/1202296.jpg> P.S (I should mentioned, that these fields are in for loop {% for movie in movies %} ) -
Can I use an API Key to identify a server that is an API consumer?
I'm facing a straightforward architectural challenge, which is that I have a central API written in Django and DRF. It has in it an API key library, in which there is an API key stored along with some other cryptographic information, and a column called "name". I can imagine with a little bit of customization I could add extra fields to this entity. I have multiple API consumers, which are themselves end-user browsable services, which communicate with this API. I need to be able to send notifications from within the centralized API - this requires access to the user's contact point, which is a URL, sometimes an IP address especially if it's behind a proxy. Since I need this URL, I need to store it somewhere perhaps in the database. There is get_base_uri() in Django, but I don't think it is for this purpose, especially since IP addresses are typically not necessarily connected to the consumer. How should I store, authenticate and authorize an API consumer's request? Should I submit the notification endpoint on every request (quite tedious), use the API key on every request (sent along with the request headers, would also need to implemented, but it would be … -

Docker on GCE always restarting
Problems I am having with my Docker instance on a GCE VM: It keeps restarting I cannot access tcp:80 after creating several firewall policies Here are the steps I took in creating the instance with gcloud: Why is Google Compute Engine not running my container?

DjangoListField analouge for an individual object resolver
I am using Django + GraphQL and it is extremely convenient to use DjangoListField. It allows me to override get_queryset at the ObjectType level and make sure all permissions verified there. In that manner I have a single place to have all my permission checks. However, whenever I need to do something like: contract = graphene.Field(ClientContractType, pk=graphene.ID(required=True)) I have to also duplicate permissions validation in the resolve_contract method. I came up with the following solution to ensure permission and avoid duplication: def resolve_contract(self, info, pk): qs = ClientContract.objects.filter(pk=pk) return ClientContractType.get_queryset(qs, info) It works but I'd love to have some sort of DjangoObjectField which will encapsulate this for me and, potentially, pass arguments to the ClientContractType in some way. Have someone had this problem or knows a better solution? -

Django - Filter by multiple values (Logical AND) on ManyToMany field
I'm trying to build job-candidate match system. I want to filter Candidates by Critical Skills needed for the Job. Every candidate has multiple skills. Every Job has multiple 'required' JobSkill which is a model that also contains importance of the skill. I want to filter my candidates and to get only candidates how have all the critical skills required for a job. A critical skill is defined as a JobSkill with importance = 3. For a given job 'job_1' I want to get the relevant candidates as follows: critical_skills = job_1.required_skills.filter(importance=3) relevant_candidates = Candidate.objects.filter('candidate how has all the critical_skills) models.py: class Skill(models.Model): title = models.CharField(max_length=100, blank=False, unique=True) class JobSkill(models.Model): skill = models.ManyToManyField(Skill) class Importance(models.IntegerChoices): HIGH = 3 MEDIUM = 2 LOW = 1 importance = models.IntegerField(choices=Importance.choices) class Job(models.Model): title = models.CharField(max_length=100, null=False) required_skills = models.ManyToManyField(JobSkill, blank=True) date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) class Candidate(models.Model): title = models.CharField(max_length=100, blank=False, null=False) full_name = models.CharField(max_length=100, blank=False, null=False) skills = models.ManyToManyField(Skill, blank=True) I would appreciate any help with this!!

Django: render template after AJAX POST request in view using context
Simple question but can't find the answer. I submit an AJAX post request from my template template1.html, my view function uses the AJAX POST data to lookup objects/context variables from the database. Then I simply want to render a different template template2.html from this view using those context variables as template tags in this next template (template2.html).

Overwrite django admin delete_queryset's "short_description"
I've been overwriting django's delete_queryset in my app (mainly to provide custom bulk deletion). I can't find the way to overwrite the "short_description" of this method. For custom methods, you can easily use the short_description attribute, for instance : class MyAdminModel(admin.ModelAdmin): def dump_model(self, request, queryset): pass dump_model.short_description = "My description" But this won't work : class MyAdminModel(admin.ModelAdmin): def delete_queryset(self, request, queryset): pass delete_queryset.short_description = "My description" I've tried every method/attribute of the standard delete_queryset (within the __init__ method after a super() call that is) without finding anything useful, though I might have missed something. I've also gave it a try deleting the standard method using delattr (also in __init__), though it seems a bit clumsy. It also fails, throwing an AttributeError : class MyAdminModel(admin.ModelAdmin): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) delattr(self, "delete_queryset") -

Django CSRF cookie not set: using Ajax Cross site

I know this problem has been asked about so many times but I don't seem to find a solution. I don't have any experience requesting a POST call in Django like this, not using DRF but endpoints of our own. The Problem Code: firstly the frontend shall make a get request for a csrf token to /api/csrf/ views.py: def get_csrf(request): # print(get_token(request)) return JsonResponse({ 'detail': 'CSRF cookie set', 'X-CSRFToken': get_token(request) }) After getting the value, the token is assigned to the cookie and a hidden element via main.js: success: function (response, status, xhr) { $('.csrftoken').attr('value', response['X-CSRFToken']); setCookie("csrftoken", response['X-CSRFToken']); } The code above works fine and we get the value, at the start, it was like this but was not working so I changed it like: xhr.getResponseHeader("X-CSRFToken") -> response['X-CSRFToken'] Now whenever the frontend makes a POST call to the back end with header:{ 'X-CSRFToken': token} running on localhost:8080 … -

Django - add ModelTranslation to already registered model
I want to add fields in my db to translate. I want to use modeltranslation link here. I added my model to translation.py: from .models import GameTask class GameTaskTranslationOptions(TranslationOptions): fields =('name', 'description', 'button_text') translator.register(GameTask, GameTaskTranslationOptions) Now I want to add admin integration. I already added GameTask to admin: @admin.register(GameTask) class GameTaskAdmin(admin.ModelAdmin): list_display = ('id', 'name', 'category', 'game', 'cycle_type', 'points', 'link_to_validity') search_fields = ('name', 'category') link_to_validity = link_to_validity What is the best way to create this connection? -
How do I extend a Django admin form's clean() function?
I have a Django 3.0 Model and associated Admin Add Form. I would like to validate entered data against other data being entered at the same time, the way you can for normal Forms -- making sure two password fields match, for example, or making sure the email and backup email fields are different. It seems like the best way to do this is to extend the clean() function for the Add page's Form, because that's the function you'd use for a normal Form. The documentation seems to give hints that this might be possible, but it doesn't give enough information to put it all together. Web searches for "Django extend Admin Form" return results only for extending the template. How do I extend a Django Admin Add Form's clean() function? -
