How to filter an existing queryset by the month instead of day
I have a queryset that displays the amount of followers for each day of the month. Views: context["brandtwitterFollowerCounts"] = ( TwitterFollowerCount.objects.filter( twitter_account=self.object.twitter_account, followers__gt=0 ) .distinct("created__date") .order_by("created__date") ) context["brandTwitterFollowCreated"] = [ i.created.strftime("%d %m") for i in context["brandtwitterFollowerCounts"] ] context["brandTwitterFollowers"] = [ i.followers for i in context["brandtwitterFollowerCounts"] Dataset: var newDataObjectTwo = { labels: {{ brandTwitterFollowCreated|safe }}, datasets: [{ label: 'Daily', backgroundColor: 'rgb(255, 255, 255)', fill: false, borderColor: 'rgb(29, 161, 242)', data: {{ brandTwitterFollowers|safe }} }], } I would like to filter this by months instead now. So as there are currently 3 months (08, 09, 10), the graph should only show 3 data points. Sorry if this doesn't make sense, I am not sure what the best way to explain it is. -

How to set attr from model field in forms in django
How to set specific attribute for html template based on model method return value or just a model field name? I have already known it's possible to override fields by __init__ function or widgets like this: models.py class Item(models.Model): title = models.CharField(verbose_name=u"name", max_length=200, blank=False, null=False) def __str__(self): return ("%s" % self.title) forms.py class ItemForm(forms.ModelForm): class Meta: model = Item fields = ['title',] widgets = { 'title': forms.RadioSelect(attrs={ 'class': 'radioselect', 'item_name': 'title name?' # <- i want to have title name here of each not statis string }), } def __init__(self, *args, **kwargs): super(ItemForm, self).__init__(*args, **kwargs) self.fields['title'].widget.attrs.update({ 'item_name': '' # <- i want to have title name here of each not statis string }) however, I want to set specific field name, based on previosly defined fields in model not just a static string like in above-mentioned example. If i add Item into a database with title = "Apple" i want to insert this string into this attribute to have such expected result like this in templates: <input type="radio" class="radioselect" item_name="Apple"> -

Django Translation - invalid token in plural form when running server
Django version 2.2.6; gettext 0.20 in Windows Environment I start using Python and Django to develop a webapp where translation is needed. Following tutorials, I ran makemessages and compilemessages without errors. Then, when I try to run the server I have the following error : ValueError: invalid token in plural form : Expression at getttext.py line 93. I already tried to flush and recreate my venv, removing my po/mo files and running the server, the error is still the same. It looks like Django mo files are causing this error and I don't know why. Probably a version mismatch between Python, Django and Gettext but I don't know how to fix it. Can you help ? -
When you exclude a field from a Django admin class, does that also prevent the field being set in a POST?
Say I have a model admin: class Customer(Model): name = CharField(max_length=255) secret = CharField(max_length=255, blank=True) @register(Customer) class CustomerAdmin(ModelAdmin): list_display = ['name'] exclude = ['secret'] The secret field is not going to appear in the admin. But if I programmatically create a POST with the secret field in, will Django prevent it from being set on the model? So is there any security risk in having an admin class for a model which has excluded fields that should not be written to from a web client? -

How to choose child model while create parent?
Is there a way to choose child model as type of parent model in a parent creation form? Some code for example: from django.db import models class Parent(models.Model): title = models.CharField( max_length=100 ) some_attribute = models.PositiveIntegerField( null=True, blank=True, ) class ThinChild(Parent): name = models.CharField( max_length=300, ) class ThickChild(Parent): platform = models.CharField( max_length=300, ) Let's say i want to be able to create both of ThinChild and ThickChild from one form. Is it possible to do this, for example, by creating an instance of the Parent model and selecting the required child from the list of child models (let's name that field "child type"), so that depending on the choice a form appears with a fields set corresponding to the selected model? -

How to dynamically pass arguments to forms in django?
I have a form 'BasicSearch', having two fields. One is a choice field called 'search_by' while the other is a text field called 'search_for'. I have models for customers, suppliers, items, projects and few others.

It works fine when I manually create a dictionary of column headers and pass it to the choice field.
