Django HStore Dictionary Field Ex

This is a subclass of hstore.DictionaryField which uses JSONFormFieldEx to render full featured forms.

How it works?

class MyCustomer(Model):
    slug = SlugField()
    store = DictionaryFieldEx({
        "profile": {
            "name": forms.CharField(max_length=10),
			"email": forms.EmailField,
        },
        "account1": {
			"number": forms.IntegerField,
			"balance": forms.DecimalField(max_digits=10, decimal_places=2),
        },
		"date_joined": forms.DateTimeField,
    })

class MyCustomerForm(forms.ModelForm):
	model = MyCustomer

And MyCustomerForm renders like this:

Usage

Patched version of DictionaryField constructor takes three arguments itself. The original DictionaryField arguments still work.

• fields: a dict of fields
  You can provide either field type or field instance for each field. Fields also supports SortedDict or [(k,v)...] to preserve ordering of fields.

• allow_json_input: True|False
  If True, it will render an additional textarea allowing user to enter arbitary json string (just like jsonfield). The value in this field will be loaded to python dict and merged RECURSIVELY into the fielded values with priority.

Note: when fields is empty, allow_json_input will be automatically set to True

• allow_empty: True|False
  If False, cleaned value dict will be filtered to keep only keys that have values.
