Google Cloud Platform: "cloud_sql_proxy.exe' is not recognized as an internal or external command, operable program or batch file."
I'm currently trying to follow Google's guide for Running Django on App Engine Standard Environment: https://cloud.google.com/python/django/appengine I get to this set of instructions: Start the Cloud SQL Proxy using the connectionName from the previous step. cloud_sql_proxy.exe -instances="[YOUR_INSTANCE_CONNECTION_NAME]"=tcp:3306 Replace [YOUR_INSTANCE_CONNECTION_NAME] with the value of connectionName that you recorded in the previous step.

Django wagtail adding favicon to root page

Getting started with django-restframework-gis on Windows 10
I have some experience with Python-Django including its REST framework, a reasonable understanding of geographic information (and what GIS is about) and about databases, and I would like to develop a "geo-aware" REST service on my Windows machine based on Django. The application shall be limited to the REST service; visual exploration and other stuff shall be developed independently. Side-remark: once my application is running, it will be ported onto a Linux machine and PostGIS will then be used instead of SpatialLite. After several hours of web-searching, I still haven't come up with a good "Quickstart" guide. There are many tutorials and docs about various aspects related to my task, but they either refer to Linux, or their installation instructions are outdated. Here is what I have done so far: 1) I use miniconda and Pycharm 2) I created a new virtual environment like so: conda create -n locations pip numpy requests activate locations conda install -c conda-forge django djangorestframework djangorestframework-gis 3) I set-up the new Django project and my application and performed a database migration: python [path-to..]\django-admin.py startproject locations cd locations python [path-to..]\django-admin.py startapp myapp cd .. python manage.py migrate 4) I added "rest_framework" and "myapp.apps.MyAppConfig" to the APPLICATIONS … -
Ordering of nested objects using a through model in DRF
i'm using Django rest framework and serialising child objects, but the ordering of the nested objects doesn't seem to be working for me. My models are: ``` class Policy(models.Model): labels = models.ManyToManyField(ClassificationLabel,through='PolicyMemberClassificationLabel') class PolicyMemberClassificationLabel(models.Model): label = models.ForeignKey(ClassificationLabel, related_name='memberLabels') policy = models.ForeignKey(Policy, related_name='parentPolicy') order = models.PositiveSmallIntegerField(blank=True) class Meta: ordering = ['order'] class ClassificationLabel(models.Model): #more model attributes I would like the ordering of the child objects to be based on the order attribute for that model. For example: [ { "displayName": "Policy1", "labels": [ { "displayName": "label1", <=order=1 }, { "displayName": "label2", <=order=2 }, { "displayName": "label3", <=order=3 } ], } ] This isn't working and i'm not getting any sensible ordering for them. I've tried ordering via the model's meta class, and have looked elsewhere on here (like here). I have also tried queries such as returnedPolicy = (Policy.objects.filter(groups__uniqueId__in=allGroups).distinct().order_by('policymemberclassificationlabel__order')[:1]) but these tend to throw FieldErrors. How can I get the returned object to have ordered nested objects based on the through model attribute if i'm querying via the Policy object? -

Django unmanaged model returns empty queryset whereas pgcli is not
I've created a view table in Postgres, which consists of fields (a,b_id,c: date, integer foreign key and decimal) Then I've created Django model: class model(Model): class Meta: managed = False db_table = 'table' a = models.DateField(primary_key=True) b = models.ForeignKey(<>) # also checked with b_id=IntegerField() c = models.DecimalField(max_digits=15, decimal_places=6) Problem is, when I query it via Django ORM, it returns an empty queryset. When I'm running the same exact query in pgcli, it returns the rows I need. I'm pretty much sure the database is the same (checked on other managed models of the app). How do I debug and fix this kind of issue? -

Django post_save: database not yet updated?
I'm writing a Django application for ordering stuff. All orders have a certain type Type. If Type.is_common == true, it needs to be included in a delivery no matter if a user orders this type or not.

Here is the code: @receiver(post_save, sender=Order) def create_common_order(sender, instance=None, created=False, **kwargs): """ This signal handler creates common orders (if delivery type definition contains any common types) for every first order of a user for a certain delivery.

Django custom User model throwing SystemCheckError - The field 'username' clashes with the name 'username'

Migrating from SQLite3 to Postgres issues with non-null constraints

Crispy-Forms Include Tag Causing Many Duplicate Templates
I have a Django site that uses the below template to render a crispy-forms model formset. Using django-debug-toolbar, I gathered that the include tags are rendering the bootstrap4 templates many, many times. I think this is what is killing my performance (i.e. 3-4 minutes to load an inline formset with 100 forms in it) How should I replace the include tags to avoid the duplicate rendering? Should I use extend somehow? I can replace the include tags with the actual html from the bootstrap4 crispy-forms templates, but those templates have nested templates as well. That creates an exercising of building a master crispy-forms template that includes everything...which seems like the wrong way to go about this. In addition, I tried replace the bootstrap4/field.html include tag with the actual html, and field.html was still duplicated, and the data lost it's table structure because of the loss of with tag='td'. {% load crispy_forms_tags %} {% load crispy_forms_utils %} {% load crispy_forms_field %} {% specialspaceless %} {% if formset_tag %} <form {{ flat_attrs|safe }} method="{{ form_method }}" {% if formset.is_multipart %} enctype="multipart/form-data"{% endif %}> {% endif %} {% if formset_method|lower == 'post' and not disable_csrf %} {% csrf_token %} {% endif %} <div> … -
Django does not add an extra attribute to the custom ModelForm widget
models.py class MyModel(models.Model): pub_date = models.DateTimeField(default=timezone.now) title = models.CharField(max_length=255, blank=False, null=False) text = models.TextField(blank=True, null=True) forms.py class MyModelForm(ModelForm): tos = BooleanField() class Meta: model = models.MyModel fields = ['title', 'text', 'tos'] widgets = { 'title': TextInput(attrs={'class': 'form-control', 'placeholder': 'Title'}), 'text': Textarea(attrs={'class': 'form-control', 'placeholder': 'Text'}), 'tos': CheckboxInput(attrs={'data-validation-error-msg': 'You have to agree to our terms and conditions'}), } Results: >>> print(forms.MyModelForm()) <tr><th><label for="id_title">Title:</label></th><td><input type="text" name="title" class="form-control" placeholder="Title" maxlength="255" required id="id_title" /></td></tr> <tr><th><label for="id_text">Text:</label></th><td><textarea name="text" cols="40" rows="10" class="form-control" placeholder="Text" id="id_text"></textarea></td></tr> <tr><th><label for="id_tos">Tos:</label></th><td><input type="checkbox" name="tos" required id="id_tos" /></td></tr> You can see that the in the TOS field data-validation-error-msg attribute is missing. Any ideas?
