• Customizable schema

Usage

You need to set the widget to needed fields into your form instance:

from collective.z3cform.jsonwidget.browser.widget import JSONFieldWidget
from zope.interface import Interface
from zope import schema


class IMyJsonSchema(Interface):
    first = schema.TextLine(
        title='first field',
        required=True,
    )
    second = schema.List(
        title="second field",
        required=False,
        value_type=schema.TextLine(),
    )

class IFormSchema(Interface):
    my_json_field = schema.SourceText(
        title="The field with some stored json values"
    )

class MyForm(Form):

    ...
    schema = IFormSchema
    fields = field.Fields(IFormSchema)
    fields["my_json_field"].widgetFactory = JSONFieldWidget

    def updateWidgets(self):
        """
        """
        super(MyForm, self).updateWidgets()
        self.widgets["my_json_field"].schema = IMyJsonSchema

With this configuration, we are setting JSONFieldWidget widget to my_json_field field and setting the fields schema defined in IMyJsonSchema interface.

In the field are stored a list of json objects where each object has a set of fields defined in the schema.

For example for the given configuration, we are going to store into the field something like:

[
    {
        "first": "a string",
        "second": [1,2,3,4]
    },
    {
        "first": "another string",
        "second": ["a", "b", "c"]
    },
]
