Remove some logs in gunicorn
Hi I am using gunicorn as a web server for django. I would like the Closing connection log to be excluded or at least somewhat avoided.. Is that possible? [2018-11-22 19:07:31 +0800] [11] [DEBUG] GET /admin/login/ {Client-IP: -, Request-time: 0.010543, Request-date: [22/Nov/2018:19:07:31 +0800], HTTP-Status: "GET /admin/login/ HTTP/1.1", HTTP-Status-Code: 200, Response-length: 1987, Http-Referrer: -, User-Agent: kube-probe/1.9+} [2018-11-22 19:07:31 +0800] [11] [DEBUG] Closing connection. -
nginx gunicorn with docker: how to use multiple dockerfiles
I'm using the following example to build a django-postgres-nginx-gunicorn web server. I'd like to have separated folders for each container. The following structure of the project works correctly. The main Dockerfile is used for the hello app (the django project): svm3_03 |____Dockerfile |____config | |____gunicorn | | |____conf.py | |____nginx | | |____conf.d | | |____local.conf | |____db | |____db_env |____docker | |__db | |__Dockerfile | |__dataForDB |__docker-compose.yml |__hello the docker-compose.yml looks like this: version: '3' ... services: djangoapp: build: context: . ... and the Dockerfile has the following line: CMD ["gunicorn", "-c", "config/gunicorn/conf.py", "--bind", ":8000", "--chdir", "hello", "hello.wsgi:application"] Everything works. Now I tried to have the same structure as the DB image also for the django app so I move the main Dockerfile and the hello directory inside the docker folder... I created a new folder inside the docker folder with name djangoapp and I moved there the Dockerfile and the hello folder. The new structure is the following: svm3_03 |____config | |____gunicorn | | |____conf.py | |____nginx | | |____conf.d | | |____local.conf | |____db | |____db_env |____docker | |__db | | |__Dockerfile | | |__dataForDB | |__djangoapp | |__Dockerfile | |__hello |__docker-compose.yml All I did then was … -

django : form_valid() missing 1 required positional argument: 'form'
I'm wondering how I can solve this issue in my form_valid() function : form_valid() missing 1 required positional argument: 'form' I'm using Django Class Based View and formsets. But, it could be possible to get IntegrityError and I added a try/except in order to save the formset when forms are valid, and redirect the template with an error message when I get this issue. class AnimalCreateView(CreateView): model = Animal template_name = 'animal_form.html' def get_context_data(self, **kwargs): context = super(AnimalCreateView, self).get_context_data(**kwargs) foo_queryset = Foo.objects.all() context['FooFormSets'] = FooFormSet(self.request.POST or None, self.request.FILES or None, prefix='foo', queryset=foo_queryset) return context def form_valid(self, request, form): context = self.get_context_data() formsets = context['FooFormSets'] if form.is_valid(): self.object = form.save() try: if formsets.is_valid(): formsets.instance = self.object formsets.save(commit=False) for element in formsets: element.save(commit=False) formsets.save() except IntegrityError: messages.error(self.request, _(f"Issue with foo")) return render(request, self.template_name) return super(AnimalCreateView, self).form_valid(form) I would like to know what I have to do in my form_valid() function in order to solve my issue and redirect user on the same template form with error message.

Django-Bootstrap formset not displaying group select as dropdown
I have a formset to display a selected subset of User information, and allow permitted people to edit it. Part of that is the users Group membership. The formset is created with modelformset_factory from django's built in User form. The problem I have is that the group field is not rendering as a dropdown. It shows all of the groups as a block, with the selected group highlighted. The template renders the form with <form action="{% url 'users:profiles' %}" method="post"> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} <div class="row form-row"> {% bootstrap_form form show_help=FALSE %} {% buttons %} <button name="submit" class="btn btn-primary btn-sm">Submit</button> {% endbuttons %} </div> {% endfor %} </form> </div> I have tried rendering each field seperately with {% bootstrap_field %}, and the group as a <select>. That rendered correctly, but then trying to change on users detail caused every form to error. Is there a way to have a dropdown in a formset? -
Fetching proper data in flutter app from djano-rest
Here I'm creating a moblie app with flutter. Also I've created the back-end with django rest framework. And now I want to use the informations on my back-end in the flutter. For Registration, I can post my user info from flutter to django rest, It works proberly. But when some of inputs are incorrect I don't know how to reflect the problem form back-end into the flutter app. For example here, the email address is incorrect: enter image description here And this is my code for fetching and getting data: void _postmessage( {@required var username, @required var email, @required var password1, @required var password2}) async { var url = 'url'; var data = { "username": username, "email": email, "password1": password1, "password2": password2 }; HttpClient httpClient = new HttpClient(); IOClient ioClient = new IOClient(httpClient); ioClient.post(url, body: data); _fetchdata(); } _fetchdata() async { List list = List(); final response = await http.get('url'); if (response.statusCode == 200) { list = json.decode(response.body) as List; print(list); } else { // list = json.decode(response.body) as List; print(json.decode(response.body)); } } As the result I get this in the output: enter image description here It's printing this on the output: flutter: {detail: Method "GET" not allowed.} Thank you … -
Renaming user model
I'm following the guide provided in this answer, but I've run into an issue. I'm renaming myauth.MyUser to myauth.User. I created my first set of migrations from other apps, converting every ForeignKey to an IntegerField. The migrations were created fine. I then changed the name or my User model and created a migration, this was also fine. I created my third set of migrations changing the fields back to ForeignKeys to the new model. These migrations also created fine. I then manually added dependencies to the migration files, so that the FK -> Int migrations required the previous version of the user app, and the Int -> FK migrations required the latest, renaming migration. All seems fine, however when I try to run manage.py migrate, I get the following error (a lot of times - for each FK): The field otherapp.Model.user was declared with a lazy reference to 'myauth.user', but app 'myauth' doesn't provide model 'user'. What is going on? Is there a way out of this situation? -

How to inherit from a template that is in another app on Django?

Djanog middleware process view after done with return render template continue to regular page
I created a custom django middleware, class CustomMiddleware(object): def process_view(self, request, view_func, *view_args, **view_kwargs): ... ... return render(request, 'accounts/xyz_form.html', {}) Now in xyz_form.html there is a form which on submit action goes to url which call the view and view save the form data. Now after the form data is saved how can that form disappear after the view complete its execution and continue with its normal execution. So what url should I pass in urls.py to call that view and on calling view the middleware gets exit. -
Is using jquery parseHTML to remove script tags enough to prevent XSS attacks?
We are using a WYSWIG Editor(Froala Editor) and storing raw HTML that is created by the user. Thus, escaping the string is not an option. I am intending to store the HTML string in a variable or a data-attribute enclosed within quotes. Then, read that HTML string and remove script tags using jquery's parseHTML as well as keep only certain attributes before loading the HTML into the editor. Is this approach enough to prevent all XSS attacks? -
Enumerate number in django template
It's a question by curiosity : So i have 4 types of choice for field of a model. class Thing(models.Model): Cat_One = (("b", "Big"), ("s", "Small"),("a","very small"),("x","xtra small")) dateCreation = models.DateTimeField(null=True, blank=True) url = models.CharField(null=True, blank=True, max_length=800) name = models.CharField(blank=True, null=True, max_length=200) catOne = models.CharField(max_length=1, choices=Cat_One, blank=True, null=True) so i can pass the choice to the django template : {% for choice in cat_One %} ... And iterate. But i would like to know , how to iterate from 1 to 4 without passing something to the django template ? Is there a way to do : {% for number in [1,2,3,4] %} or something with a forloop counter ? regards -
Storing and running user defined functions from a database in Django
This is a rather weird use-case, however, a project we are developing needs a way for it to store user-defined functions and run them within views. The function code will be stored in a TextField in a model. The functions themselves would be ideally very simple, mostly involving arithmetic operations, if-else blocks, and loops. The functions can also be in any language, as long as Python is able to run them somehow. The obvious problem is the possible security issues, since it is always best to assume the code will come from untrusted sources. Anyway, we have thought about these possible solutions: Storing Python functions as strings, and running them using eval(). Storing Javascript functions as strings, and running them using Js2Py. Creating a simple programming language, a subset of Python, which removes all the methods and operators which could possible cause security issues. The function would therefore be written in this new language. What is my best option? Obviously, the first two options are very insecure, while the third one is hard to implement. Is there a better way to do this? -

How to use the parallel flag in django test calls when using psycopg2 for postgresql calls inside of the tests
When we use ./manage.py test ... all is well. Once we add --parallel 8 (as we have quad core machines with HT), we get "connection already closed" errors from psycopg2. This answer seems to suggest that the issue lies in the fact that django creates a connection and then starts branching off from the main thread --> all threads really share the connection. Now if one of them closes the connection, all their connections are closed and the DB starts refusing transactions on that conn. How do we go ahead and allow testing our codebase without having to mock all DB calls now? Personally, I'd like to mock the DB but (according to project mgmt) it will be an enormous overhead to fix several hundred tests for this. So: Is there A) a nice drop in DB mock that might keep all records in memory for tests or B) a way to allow several threads to work with psycopg2? -
