08. Forms and question widgets

As mentioned before, a Trial may contain a Form, which present one or more questions to the user. We have a choice of multiple question widgets:

• Autocomplete
• ButtonArray
• Checkboxes
• Dropdown
• Radios
• TextRange
• IconRange
• String

Initializing a Question

An example of how a question is initialized in the Python backend:

question = RadiosQuestion(
        key=key,
        question=_('Does this sound like song or speech to you?'),
        choices=[
            _('sounds exactly like speech'),
            _('sounds somewhat like speech'),
            _('sounds neither like speech nor like song'),
            _('sounds somewhat like song'),
            _('sounds exactly like song')],
        result_id=prepare_result(key, session, section=section, scoring_rule='LIKERT')
    )

The key is a short name of the question. With every question, we also send a result_id. This means we can already register information in the database, such as (in this case) the section this question refers to, or the scoring rule by which we assign a score after the participant gives a response.

Initializing a Form

After defining the question above, we can then wrap it in a form as follows:

form = Form([question])
