Django Model MultipleChoice
I know there isn't
MultipleChoiceField for a Model , you can only use it on Forms.
Today I face an issue when analyzing a new project related with Multiple Choices.
I would like to have a field like a
choices with the option of multiple choice.
I solved this issue other times by creating a
CharField and managed the multiple choices in the form with a
forms.MultipleChoiceField and store the choices separated by commas.
In this project, due to configuration, I cannot do it as I mention above, I need to do it in the Models, and I prefer NOT to edit the Django admin form neither use forms. I need a Model Field with multiple choices option
- Have someone solved anything like this via Models ?
Maybe overriding some of the models function or using a custom widget... I don't know, I'm kinda lost here.
I'm aware off simple choices, I would like to have something like:
class MODEL(models.Model): MY_CHOICES = ( ('a', 'Hola'), ('b', 'Hello'), ('c', 'Bonjour'), ('d', 'Boas'), ) ... ... my_field = models.CharField(max_length=1, choices=MY_CHOICES) ...
but with the capability of saving multiple choices not only 1 choice.
You need to think about how you are going to store the data at a database level. This will dictate your solution.
Presumably, you want a single column in a table that is storing multiple values. This will also force you to think about how you will serialize - for example, you can't simply do comma separated if you need to store strings that might contain commas.
However, you are probably best off using a solution like django-multiselectfield
