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.
