Editing the user profile page with additional fields

Adrian also suggested using the registration_form_created signal to create the new field which is probably better than hooking into create_personal_data_fields.

Thank you very much for your help! I managed to create a new field like this successfully, and it works:

section_to_add = sender.sections[0]
        field1 = RegistrationFormField(
            registration_form=sender,
            parent=section_to_add,
            title="GitHub Username",
            input_type="text",
            is_required=False,
            position=1,
        )
        field1.data, versioned_data = field1.field_impl.process_field_data({})
        field1.current_data = RegistrationFormFieldData(versioned_data=versioned_data)
        section_to_add.children.append(field1)

My final question is, how can I prefill the registration form, which hook/signal can I use to intercept the form? I tried with schema_post_dump, schema_pre_load, schema_post_load, but canā€™t see a similar form info to the one in profile page. What would be the best way to approach this?

Edit: I am guessing there is something I can use in indico.core.signals.event but havenā€™t figured out testing the signals here yet.

For sure this time itā€™s the final question!

Intercepting the get_user_data I can currently add info for text areas, however, for single or multi-choice areas, I couldnā€™t prefill like this ( testing example ):

    def _get_user_data(self, sender, func, args, **kwargs):
        print("Intercepted get_user_data call")
        # Call the original function to get the base data
        user_data = func(*args.args, **args.kwargs)
        user_data["field_208"] = "DevOps" # Text area
        user_data["field_209"] = ["m"] # Single choice
        user_data["field_210"] = ["veg"] # Multi choice
        print("Final user_data with custom fields:", user_data)
        return user_data

For single choice, I both tried sending it as string ( "m" ) and the list as above, both not working. I have been trying to fix it for a while but couldnā€™t figure out what I am missing. I have the config for the fields as follows:

    # Text Field
    {"name": "product", "title": "Product", "input_type": "text", "is_required": False},
    # Single Choice Field 
    {
        "name": "shirt_size",
        "title": "T-Shirt Size",
        "input_type": "single_choice",
        "is_required": True,
        "item_type": "dropdown",
        "choices": [
            {"id": "s", "caption": "Small"},
            {"id": "m", "caption": "Medium"},
            {"id": "l", "caption": "Large"},
            {"id": "uxl", "caption": "Extra Large"},
        ],
    },
    # Multi Choice Field 
    {
        "name": "dietary_options",
        "title": "Dietary Options",
        "input_type": "multi_choice",
        "is_required": False,
        "item_type": "checkbox",
        "choices": [
            {"id": "veg", "caption": "Vegetarian"},
            {"id": "vegan", "caption": "Vegan"},
            {"id": "gf", "caption": "Gluten-Free"},
            {"id": "halal", "caption": "Halal"},
        ],
    },

and this is how I add them to the form:

       section_to_add = sender.sections[0]
        for idx, field_meta in enumerate(self.custom_fields, start=1):
            field = RegistrationFormField(
                registration_form=sender,
                parent=section_to_add,
                title=field_meta["title"],
                input_type=field_meta["input_type"],
                is_required=field_meta["is_required"],
                position=idx,
            )

            field_data = {}
            if field_meta["input_type"] in ("single_choice", "multi_choice"):
                field_data = {
                    "item_type": field_meta.get("item_type", "dropdown"),
                    "with_extra_slots": False,
                    "is_enabled": True,
                    "choices": [
                        {
                            "id": c.get("id"),
                            "caption": c["caption"],
                            "is_enabled": True,
                        }
                        for c in field_meta.get("choices", [])
                    ],
                }

            # Initialize field data
            field.data, versioned_data = field.field_impl.process_field_data(field_data)
            field.current_data = RegistrationFormFieldData(
                versioned_data=versioned_data
            )

            section_to_add.children.append(field)

I have been playing with the code, trying to figure out what might be wrong by checking the source code etc, but couldnā€™t figure out the problem. The field appears in the form as it should, but I canā€™t prefill it or send the registration form. What am I missing here?

Edit: I am sorry, registering actually DOES work. I deleted that part from my original question However, prefilling is still the issue, and canā€™t prefill at the moment, so that question still stands! Thanks!

Ahh I was supposed to pass a dictionary like :

        user_data["field_208"] = "DevOps" # Text area
        user_data["field_209"] = {"m": 1} # Single choice
        user_data["field_210"] = {"veg":1, "gf":1} # Multi choice

Solved!

Please note that the ids of choice items are typically uuid4 UUIDs. While anything else may work, I highly recommend to use UUIDs in case we ever add stronger validation there.
