How to fix LNK1104: cannot open file 'MSVCRT.lib' outside c++
I want to install django-admin in my project in virtualenv.

Django staticfiles not loading in Production
I have created one Django project. It has several static files like CSS, JS, images etc. Below is file structure mysite |- mysite |- myapp |-- static |-- CSS |-- JS |- staticfiles settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) In developer mode, I'm able to serve the static files. But to serve static files in Production mode I run below command python manage.py collectstatic And it collected all the static files to staticfiles directory at the root of the project. But with some warnings like one below Found another file with the destination path 'admin/css/vendor/select2/LICENSE-SELECT2.css'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path. But when I visit my website css and js were missing. It didn't find the static files. I'm using Django 2.2. I've 'django.contrib.staticfiles' in my installed apps. But it's not serving files. Please don't mark it as duplicate. I've tried all possible ways but I didn't get success with it, that's why I've created a new question. -

Need to have url like /stories/<id>/episodes/1
When I create a new episode, id automatically increments. What I need? Imagine, I have 10 episodes for a different stories, so if I create an episode for story(for example, with id=5), it will assign id for new episode as 11. Url will be like /stories/5/episodes/11, but I need something like /stories/5/episodes/1. It would be good to store episodes id according to story, not all number episodes from all stories. How to do that? class Story(models.Model): title = models.CharField(max_length=255) description = models.TextField(max_length=255) cover = models.ImageField(upload_to=upload_location) created_at = models.DateTimeField(auto_now_add=True) author = models.ForeignKey(User, on_delete=models.CASCADE) class Episode(models.Model): title = models.CharField(max_length=255) description = models.TextField(max_length=255) created_at = models.DateTimeField(auto_now_add=True) story = models.ForeignKey(Story, on_delete=models.CASCADE) -

I would like to have a chained dropdown with elasticsearch as back end using Django. I have two indices in ES and I will use index A for the chained dropdown and index B for the search given contraints selected in index A using common fields.

Django logs colors depending on error level, without module

how to deploy Web server & API server in 1 heroku app? Heroku + Docker (deployed with heroku.yml)
I want to deploy Vue app whose script has a couple of ajax request to django API server like follows: getRecordList: function(){ this.records = []; this.$axios .get('http://[ip address for API server]') .then(response => {}) .catch(err => {}) }) I am thinking to deploy this app to heroku with the following heroku.yml.

Django: pre-fetch custom model field (django-simple-history)--performance optimization
I am trying to optimize my querysets. I extensively make use of django-simple-history I have models as follows wherein I have a method with which I want to track changes to the fields: class TrackHistoryMixin(models.Model): history = HistoricalRecords(inherit=True, cascade_delete_history=True) has_history = models.BooleanField(blank=True, default=False) class Meta: abstract = True @property def changed_fields(self): first_record = self.history.last() latest_record = self.history.latest() delta = first_record.diff_against(latest_record).changed_fields no_history_fields = ['from_portal', 'has_history', 'document'] for field in no_history_fields: try: delta.remove(field) except ValueError: pass return delta @property def old_portal_values(self): if self.changed_fields: old_object = self.history.last().__dict__ old_portal_values = dict() for field in self.changed_fields: old_portal_values.update({field: old_object[field]}) return old_portal_values The problem with performance is that I cannot use select_related, or prefetch_related with the history field above. Thus, when I load an instance of a model which inherits from the TrackHistoryMixin, and I need to interact with the history field, it hits the database. The best thing I could do so farin my templates is that for each record I put the history field in a variable with {% with variable=object.history %}. But given that I have numerous records, performance still suffers. How can I prefetch such field such that when I get a queryset, all the history related data are loaded as well? I … -

Django urls with UUID issue
I am trying to redirect to the view based on the CustomerID but its not working for UUIDs. It was previously working fine with integers. Please suggest. url.py: from django.urls import path, include from . import views urlpatterns = [ path('create/', views.create, name='create'), path('<uuid:customer_id>', views.detail, name='detail'), path('search/customers/<uuid:customer_id>', views.detail, name='detail'), path('customers/<uuid:customer_id>', views.detail, name='detail'), path('edit/<uuid:customer_id>', views.edit, name='edit'), path('modify/<uuid:customer_id>', views.modify, name='modify'), ] views.py @login_required def detail(request, customer_id): customer = get_object_or_404(CustomerMaster, pk=customer_id) return render(request, 'customers/detail.html',{'customer':customer}) -
Is there a way that to "docker-compose build" utilize existing dependencies wheels?
To make a change in the dependencies of a docker container, i'm runing docker-compose build. I want to update a dependency listed on requirements.txt to be more specific. But everytime that I execute this, it redownload all the requirements again instead of use existing wheels. Am I missing something or is this the behavior by default? Is there a way change this behavior to make use of wheels created before?
