Django Serve Files From External Storage Directly
I have a Django project built on Google Cloud Platform. We are using Django's auth system, and most (nearly all) users do not have credentials set up in the GCP project, so all file auth needs to be based on Django and not GCP. Our backend configuration for file storage is very basic, and files are successfully uploaded to GCS as expected: DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' GS_BUCKET_NAME = 'my-bucket' The generated URLs for files are of the form (again, as expected): https://storage.googleapis.com/my-bucket/my-document.txt The problem is this bucket cannot be made publicly readable as files have access controls based on rules set up in Django's permission system that are different per user. How can I have Django serve the file instead of the file being served by GCS? One thought that comes to mind is to have views that load files from GCS and pass them through to the requesting client, but I suspect this will not handle large files well as I need to either load the entire file into local memory (bad) or load the file in chunks and write them out to the response stream in those chunks, but don't know if this can be done in Django. -
Django Settings variable *sometimes* getting reset and unsure why
I have a dict defined in my Django settings.py to act as a sort of...fake, temporary cache of data for all of my users. However, it has come to my attention that it is not behaving the way I would like and is resetting back to it's default value seemingly at random. settings.py # initialize with a fake key:value for ease in logging STORE_DATA = {'hello': 'goodbye'} views.py def get_data(name): from apiclient.discovery import build search_q = name service = build('youtube', 'v3', developerKey='<key-here>') results = service.search().list( part='snippet', channelId='<channel-here>', type='video', q=search_q, ).execute() settings.STORE_DATA[name] = results['items'] result = settings.STORE_DATA[name] return result page.videos = [] if page.name in settings.STORE_DATA: page.videos = settings.STORE_DATA[page.name] else: page.videos = get_data(page.name) This is the only code that references this global variable. It's just simply storing the results of a youtube api call so we don't have to make a query every time someone visits the page. However - sometimes this works, sometimes it doesn't. Sometimes the key:value pairs stored in the dict get reset back to it's initial state. Here is a little print out from my log - cache before the call - [u'hello'] "page1" - 2018-08-22 23:23:47 cache after the call - [u'page1', u'hello'] cache before the … -
Django testing - spoofing an Ajax POST request method with Client() to pass request.is_ajax() validation
Not sure if this is possible, but I have the following validation check for an Ajax POST request in my views.py: if request.is_ajax() and request.method == 'POST': # Do some amazing stuff here... context['is_ajax'] = True Now, running a few tests in the shell: from django.test import Client >>> c = Client() >>> response = c.post('/login/', {'username': 'john', 'password': 'smith'}) >>> response.context['is_ajax'] >>> undefined So my question is, is there a way with the test Client to spoof an Ajax request...passing the is_ajax() validation check on the request POST object, is this done by adding something to headers? I think the header should be HTTP_X_REQUESTED_WITH='XMLHttpRequest' - how would this be passed in to the c.post() method? -
Django - Forms - assign custom attributes to forms in forms.py
The question title might be a little misleading, but I couldn't think of a better title. If you've got better title, please edit the title. I have following set of models.py and forms.py` # models.py class BHA_Component(models.Model): field_1 = models.CharField(max_length=100) field_2 = models.CharField(max_length=100) field_3 = models.CharField(max_length=100) # forms.py class BHA_Component_Form(forms.ModelForm): class Meta(): fields = '__all__' I want to create custom attributes for each field, so that I can identify what kind of field it is on the Front-End, and assign a class for each field type. Something like this: Some fields are just plain blank, some are grey, some are purple, and some have check boxes. These are done by manually giving each field a particular HTML class on the Front-End. However, I want to give each field some attributes on the Back-End, and have those attributes identified on the Front-End. So, something like this: {% for field in bha_component_form %} {% if field.custom_attribute == 'option_1' %} {{ field|add_class:"has_checkbox"}} {% else if field.custom_attribute == 'option_2' %} {{ field|add_class:"blue_background"}} {% else %} {{ field|add_class:"plain"}} {% endif %} {% endfor %} How can I do this? -
How to pass raw xml into django sitemaps?
OVERVIEW: Hi, I'm trying to do the above. I'm using the sitemap framework with a custom template to put all my links in the xml file. It works fine up to a point. All the objects from the database and the static views show up perfectly. But for seo reasons, I want to add some raw xml for some images that are in the static folder. And because they're static, they're not saved into the database, so I can't get them and any special search term values there. My assumption is that I have a file pathing problem with my picture_seo variable. Here's an example of what I have so far, and an Idea of what I want done: URLS.PY from django.contrib.sitemaps import views as sitemap_views from django.views.decorators.cache import cache_page from .sitemaps import HighPrioritySitemap, LowPrioritySitemap # picture_seo = 'picture_seo.html' # not working when I uncomment it sitemaps = { 'high_priority': HighPrioritySitemap, 'low_priority': LowPrioritySitemap, # 'picture_seo': picture_seo # I want this passed in too but can't figure out how } urlpatterns = [ path('sitemap.xml', cache_page(60*720)(sitemap_views.index), {'sitemaps': sitemaps}), path('custom-sitemap-<section>.xml', cache_page(60*720)(sitemap_views.sitemap), {'sitemaps': sitemaps, 'template_name': 'sitemap_test.html' }, name='django.contrib.sitemaps.views.sitemap'), ] DIRECTORY STRUCTURE: ... manage.py some-templates/ picture_seo.html # was told to make an html file for … -
Patch method doesn't work with Django REST Framework
I'm trying to enable partial update in Django web app. The model I want to update includes ImageField.

Django form not rendered by auth_views.LoginView
I have a problem that is that Django is not rendering one of the fields of my Login form. I'm using the auth_views.LoginView view for user authentication, and even if I put my template, one of the fields does not appear in my html.

Jinja2 inside jinja2
I have the following code: <img src="{% static 'imatges/{{i.sideid.sidepic}}' %}"/> But it doesn't load the picture... If i change the {{i.sideid.sidepic}} to the picture name "republic.png" it works tho. So, yeah, {{i.sideid.sidepic}} is actually the exact same name ("republic.png"), because i do a print in django views and shows it in my cmd, the exact same name "republic.png" . I guess it has a specific way to add that {{i.sideid.sidepic}} inside the jinja {% %} . Thanks all! -
Mixer.blend() module cannot properly create an instance that is referencing custom User object with UUID as PK
I am trying to run tests of my models using pytest. I am having trouble with using mixer on a SQLite3 in ":memory:" database. I have a model named Category that has a foreign key attribute called "created_by" which references my custom User model. When assigning the referenced model of User to the category variable in mixer.blend() I get an exception that says that the User instance is not that of a UUID. See my test below: import pytest from mixer.backend.django import mixer from apps.API import models pytestmark = pytest.mark.django_db class TestCategory(): def test_model(self): category = mixer.blend(models.Category) assert category.pk == 1, 'Should create a Category instance' This is very strange as this worked previously (about a week ago). Why can mixer not coerce the UUID from the primary key of my User object? If anyone has any ideas I am all ears. Below I define my models and show a few stack traces. Hopefully, we can find some insight. Here is the stack trace in pytest: self = <django.db.models.fields.UUIDField: id>, value = <User: doliver@smith.com> def to_python(self, value): if value is not None and not isinstance(value, uuid.UUID): try: > return uuid.UUID(value) venv/lib/python3.6/site-packages/django/db/models/fields/__init__.py:2325: self = <[AttributeError("'UUID' object has no attribute 'int'") raised … -
How to increase upload image size on Nginx server?
I have developed an application in Django. I was stuck in the problem that some image(size:2MB)was uploaded successfully while some images(size:4,5MB) generate an error after upload. After research, I found that this issue is due to my Nginx server file upload size.

Extending Django-admin's DateFieldListFilter for custom "Upcoming" filter
I am trying to add a custom "Upcoming" filter to the Django Admin DateFieldListFilter. It's really simple, just selecting dates after today. Building on this thread i was able to extend Django's standard DateFieldListFilter into my own custom one as follows : class MyDateTimeFilter(DateFieldListFilter): def __init__(self, *args, **kwargs): super(MyDateTimeFilter, self).__init__(*args, **kwargs) today = datetime.now() self.links += (('Upcoming'), {self.lookup_kwarg_since: today.strftime('%d %B %Y')}), It correctly displays "Upcoming" at the bottom of my filters, but clicking does not actualy filter the results. I do not know what's wrong with my syntax and I have tried many alternatives... Your help is very much appreciated! PS: I am using Python 3.5.2 and Django 2.0.6 -
override save to act as save and continue on add
I have an Model Admin that requires at least one associated inline record. The inline form is not displayed on add, only on change. I would like for the 'save' button to behave as 'save and continue editing' only when the change_form is adding a record (this seems less complex than hiding the save button while showing the save and continue in this case only). The 'save'and 'save and continue editing' buttons should behave as normal when modifying, only behave differently during add. Thanks! -
PostgreSQL full text search doesn't work in some case (Django)

django locale is not loading correctly

Django: How would I translate keys in an HTML template with values in a CSV?
I'm facing a few troubles in regards to getting started with some work I'm doing involving translations. I currently have a .csv file that is formatted as such: KEYS,en-US,ko-KR active,Active,사용 여부 actual,Actual,실적 경비 addNewCostType,Add New Cost Type,경비 등록 etc... and am trying to use this CSV as an i18n file for an HTML file I'm creating using Django to dynamically insert data into the file. Ideally what I'd like to do is have a table in the HTML file where the header is a key and then based on the locale of the browser Django will insert the proper translation. I saw a few examples where users were able to use .JSON files to do this but I was curious if there was a way to use the .csv that I currently have to achieve this as it would save a lot of time. I think my code is supposed to be something like {% load i18n %} <table> <tbody> <tr> <th>{% trans trainingTitle %}</th> <td>{{training_title}}</td> <th> {% trans targetAudience %}</th> <td>{{audience}}</td> </tr> </tbody> </table> but I don't know how to reference the .csv or really much about how translations work in Django's template rendering.

Django: update model field using button
I would like to use a button to update a field (claimant) in one of my models (PieceInstance) and then redirect the user to a page where he sees all of the claimed instances.

Changing admin classes in runtime
I want to change admin classes programmatically without restarting server. I want to for example change list displays of a model in runtime. Now it only changes when I restart the server... Example (Versionadmin is an extention of modeladmin): admin.site.unregister(model) class YourModelAdmin(VersionAdmin): list_display = new_list_display admin.site.register(model, YourModelAdmin) This works if I run it in admin.py, but if I run it when the admin site is already setup, nothing changes. Any idea how to go about this?
