Enforcing row level permission in Django Models
I am trying to enforce row (object) level permissions in Django, on the model level. All the resources on the web revolve around two possible solutions: Option 1. Passing the request manually to a custom manager with a for_user() method: # manager class EntryManager(models.Manager): def for_user(self, user): return self.get_queryset().filter(owner=user) # model class Entry(models.Model): owner = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) objects = EntryManager() # usage in views/serializers/forms/admin/... Entry.objects.for_user(request.user) Option 2: Using threading.local() variables to store the request/user in the middleware, and than access them in the model. Examples: https://github.com/benrobster/django-threadlocals https://github.com/Alir3z4/django-crequest https://www.viget.com/articles/multi-tenancy-in-django/ I don't like option 1, because it relies on a developer calling a for_user() method, which can be often forgotten. There are a lot of people on the internet that don't like option 2, because of the usage of threadlocals and also because of a Django philosophy that models should be request-unaware. I am coming from a framework such as Laravel which allows access to the Request and User at all levels, so I am puzzled why this is a no-no in Django. I did take a look at django-guardian as well, but the module seems quite complex, and no easy way to filter out all objects linked to a user. Also … -
How to style grouped checkboxes from CheckboxSelectMultiple in django with crispy_form
Here is my form: class MyForm(forms.ModelForm): foo = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(attrs={'class': 'flat'})) class Meta: model = MyModel exclude = ['bar', 'baz'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) choices = ( ('Groupe1', ( (1, 'Item1'), (2, 'Item2'), )), ('Groupe2', ( (1, 'Item1'), (2, 'Item2'), )), ) self.fields["foo"].choices = choices self.helper = FormHelper(self) self.helper.form_id = 'myform_id' self.helper.form_class = 'myform_class' self.helper.form_method = 'GET' self.helper.use_custom_control = True self.helper.label_class = 'font-weight-bold' Once rendered, I would like to change the style of the group labels. But I don't know how to access it. When I inspect my form, I see the structure looks like this: <form> <div class="form-group"> <div class="controls"> <strong>Groupe1</strong> <div class="checkbox"> <label class="" for="id_actes_select_0_0"> <div class="icheckbox_flat-green" style="position: relative;"> <input type="checkbox" name="foo" value="Item1" class="flat" id="id_actes_select_0_0"> </div> Item1 </label> </div> ... </div> </div> </form> Group labels are wrapped in strong tags.

Django not migrating CharField with choices properly
I have a model Car with a CharField color, that has the choices of white, black and blue. class Car(models.Model): WHITE = "White" BLACK = "Black" BLUE = "Blue" COLOR_CHOICES = ( (WHITE, "White"), (BLACK, "Black"), (BLUE, "Blue"), ) ... color = models.CharField(max_length=20, choices=COLOR_CHOICES, default=BLUE) I already have created Car objects with a color. Now when I introduce a change to the choices (e.g. change BLUE to RED in all occurences, as well as in the default) and run the migrations, the Car objects of color BLUE that already exist do not get migrated to RED. And that's where the weirdness begins: When I use the django shell to check the objects, they appear as Car.BLUE (the choice that no longer exists). When I inspect the objects in the Django Admin, they appear as Car.WHITE. When I create a new object, it works - it becomes Car.RED automatically (picks up the default). Questions: Are there any specific steps that I missed when migrating choices for the CharField? Why could this weird behavior be happening and how can I safely fix? Do I have to manually (or through a script) fix the data? I expect upon migration all existing Car.BLUE objects … -
How to assign an empty value to an object attribute in Django Admin Interface?

Django : stripping HTML after a search filter with dynamic parameters
Some of my database entries contains HTML, and I found here a way exclude HTML from the search so that a user who searches "strong" doesn't get any entry that contains a tag for example. The issue here is that my search contains a dynamic variable wordcontentfilter that looks into a Sense ForeignKey that is "linked" to Mot and that I don't know how to write the part of the if code if query not in strip_tags(i.wordcontentfilter) properly.
