Serving gzip content from Django TemapleView
I am using TemplateView to render my pages. Recently I started using webpack to compress my js files into a gzip format. I now want to modify my Template view to render the gzip file. Currently I'm setting the TemplateView's component field to <my_component>.js and I want to change it to <my_component>.js.gz. For that I need to set up the content-encoding header param of the response to 'gzip'. Is there a way to do it somehow in the TemplateView class? I dont want to change the class because I dont really want to deal with the HttpResponse builerplate. -
Configure batabase for production/project managment
My ultimate goal is to create a Django based (so with Python) web application to handle production activities (at work). In other word, something similar to project managment app, with different task for each project etc. But, before thinking about Django "world", I was thinking about how to define the underlying database. First of all let me explain what I mean. Let's assume that I have to produce object OBJ1. To do that I have to complete a certain number of tasks, say TSK1, TSK2,TSK3. The same for OBJ2, OBJ3 and so on... So, each "Object" has its own (different from object to object) sequence of tasks, with their own duration. Now I may have to produce 5 pieces for OBJ1, 40 for OBJ2, and so on, and every "instance" of OBJx could have different delivery date (tasks have different duration, from 1 hour to 7 days for example, it depends). I'd like to be able (at the end of the project) to add every OBJs to a page where I can update the tasks status, to control the progress and check for delay and so on. At the end... I'd like to be able to "handle": different project (obj) … -
Django Crispy Forms - Display List of Dictionaries
Take the following list of dictionaries as an example: {"host": "test-01", "service": "tomcat"}, {"host": "test-02", "service": "tomcat"}, {"host": "test-03", "service": "tomcat"}, {"host": "test-04", "service": "tomcat"}, {"host": "test-05", "service": "postgres"}, {"host": "test-06", "service": "tomcat"}, {"host": "test-07", "service": "tomcat"}] I essentially want to create a HTML message for each dictionary saying what service is going to be restarted on what server. However, I'm not sure what the best way of going about this is. I've tried the below to no avail: views.py def restart_es_services_confirm(request): systems = [{"host": "test-01", "service": "tomcat"}, {"host": "test-02", "service": "tomcat"}] form = ServicesConfirm(request=request) if request.method == 'POST': return HttpResponseRedirect('restart_services.html') else: form = ServicesConfirm(request=request) return render(request, 'restart_services_confirm.html', {'form': form}, {'systems': systems}) restart_services.py class ServicesConfirm(forms.Form): reconfirm = forms.BooleanField(required=True, label='I confirm these services can safely be restarted.',widget=forms.CheckboxInput(attrs={})) def __init__(self, *args, **kwargs): request = kwargs.pop("request") super().__init__(*args, **kwargs) systems = request.session['systems'] for system in systems: host = system['host'] service = system['service'] message = ("Restart " + service + " on " + host) self.helper = FormHelper() self.helper.add_input(Button('cancel', 'Cancel', css_class='button button--wide button--black', formvalidate='formnovalidate', onclick="window.location.href = '{}';".format(reverse('home')))) self.helper.add_input(Submit('deploy', 'Deploy', css_class='button button--wide button--white')) self.helper.form_method='POST' self.helper.layout = Layout( Fieldset( 'Confirmation', Row( Column('reconfirm', css_class='form-group col-md-14 mb-0') ) ) ) restart_services_confirm.html: <!doctype html> <html lang="en"> {% load static %} … -
Django - How to query a list inside of a filter method
I am new to Django and I want to query a list inside of an object. I have a list of Batches and each batch has a BatchComment list. Both of them has a User property. What I want to do is get batches where user has a comment and only get ones where the last comment is not made by the user. How can I achieve this? Currently I am retrieving batches that user has comment by Batch.objects.filter(comments__user=self.request.user) I want something like Batch.objects.filter(comments__user=self.request.user).filter(comments_last__user!=self.request.user) -
input_formats in Django ModelForm DateTimeInput throwing TypeError
I have seen a lot of questions on this and all the answers seem to be because input_formats was incorrectly being placed on the DateTimeField on the model and not on the form.

I am using Cryptocompare.com api to load news from cryptocurrencies world. In the template I am looping through it show it on the home-page.

Testing django mail and attachment return empty

Django wizard forms and dynamic formset creation
Usually, in a wizard, we declare forms or formsets in static way, for example with something like: form_class=formset_factory(MyForm, min_num=1, extra=5) # let's say this is step '4' But now, what if I need data from step 3, to know how to define the min_num or extra value for the formset of step 4? I was thinking of doing such thing in the get_form() method: def get_form(self, step=None, data=None, files=None): form = super().get_form(step, data, files) # .... elif step == '4': step3_data = self.storage.get_step_data('3') # ... here I would parse step 3 data, to be able to define: computed_step_4_min_num = 5 computed_step_4_extra = 10 # And here I would need to call formset_factory(min_num=computed_step_4_min_num, extra=computed_step_4_extra), # but how? This is obviously not the right place for this call. While it's easy to edit form fields attributes in the get_form() method, I did not find a way to define the right number of forms of a formset, in a dynamic way. I read documentation but I could have missed it. Thanks for your help. -

Creating Two Custom Singin Forms using django_allauth

Define permissions to existing users for viewing or modifying other users
I'm currently learning my way around the permission framework in Django and I'm looking to define a set of permissions to a user, which defines if they can see or modify other users in the system. I'm using the django.auth framework on a multi-schema database where each schema has its own set of users. I want to essentially apply this, but to the built-in users model. class Meta: permissions = ( ("can_view_users", "Can view all users"), ("can_modify_users", "Can modify all users"), ("can_password_reset_users", "Can reset passwords for all users"), ("can_delete_users", "Can delete all users"), ) However I cannot seem to find any documentation on applying this logic to the built-in authentication framework. -

django channels async consumer blocking on http request
I have the following async consumer: class MyAsyncSoncumer(AsyncWebsocketConsumer): async def send_http_request(self): async with aiohttp.ClientSession( timeout=aiohttp.ClientTimeout(total=60) # We have 60 seconds total timeout ) as session: await session.post('my_url', json={ 'key': 'value' }) async def connect(self): await self.accept() await self.send_http_request() async def receive(self, text_data=None, bytes_data=None): print(text_data) Here, on connect method, I first accept the connection, then call a method that issues an http request with aiohttp, which has a 60 second timeout. Lets assume that the url we're sending the request to is inaccessible. My initial understanding is, as all these methods are coroutines, while we are waiting for the response to the request, if we receive a message, receive method would be called and we could process the message, before the request finishes. However, in reality, I only start receiveing messages after the request times out, so it seems like the consumer is waiting for the send_http_request to finish before being able to receive messages. If I replace await self.send_http_request() with asyncio.create_task(self.send_http_request()) I can reveive messages while the request is being made, as I do not await for it to finish on accept method. My understanding was that in the first case also, while awaiting for the request, I would be … -

Actually, it is a question of best practice and elegance. Imagine I have JS code like this: my_js_func() { let var_coming_from_backend = {{ some_var || '' }} if (...) { } } What is the most proper way to check some_var is None? Currently, I am doing that this way: let var_coming_from_backend = {{ some_var|default:'' }} if (var_coming_from_backend == '') { } But it seems like junk code to me.
