My model looks like this:
from django.contrib.postgres.fields import ArrayField
class Trigger(models.Model):
solutions = ArrayField(models.TextField(blank=True, null=True), blank=True, null=True, help_text='some helpful text')
This allows me to enter a list of solutions separated by a comma by default. For example: I can enter in that textfield:
1. watch out for dust.,
2. keep away from furry animals.,
This does create a list of two separate string items. However, if a solution text itself contains a comma, for example:
1. cockroaches, polens and molds might be harmful.
This will create two separate solution lines, because of the existence of a comma in that sentence.
How do I tell django to use a different delimiter than comma as it would be almost certainly a part of sentences. How can I use a separator like '|'? I looked inside the arrayfield class, but it doesn't allow any separator.
Some relevant documentation:
If you're using built in forms on the admin site, or using a ModelForm without customising any fields then the field is probably automatically using the SimpleArrayField form field. It looks like you can override the delimiter character. The documentation states this caveat:
The field does not support escaping of the delimiter, so be careful in cases where the delimiter is a valid character in the underlying field. The delimiter does not need to be only one character.
Anyways, you could do this by providing a custom form like this...
# forms.py
from django import forms
from .models import Trigger
class TriggerForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['solutions'].delimiter = '|' # Or whichever other character you want.
class Meta:
model = Trigger
fields = '__all__'
And if this is for use in the admin site...
# admin.py
from django.contrib import admin
from .forms import TriggerForm
from .models import Trigger
@admin.register(Trigger)
class TriggerAdmin(admin.ModelAdmin):
form = TriggerForm
