                                 Form

A JEP-0004 compliant data form.

Additionally to the direct access to the contained fields via the fields attribute, Form object provides an iterator and mapping interface for field access. E.g.:

    for field in form:
        ...

or:

    field = form['field_name']

### __init__(self, xmlnode_or_type=`'``form``'`, title=None, instructions=None, fields=None, reported_fields=None, items=None) (Constructor) | source code
Initialize a Form object. Parameters: `xmlnode_or_type` (`libxml2.xmlNode` or `str`) - XML element to parse or a form title. `title` (`unicode`) - form title. `instructions` (`unicode`) - instructions for the form. `fields` (`list` of Field) - form fields. `reported_fields` (`list` of Field) - fields reported in multi-item data. `items` (`list` of Item) - items of multi-item data. Overrides: object.__init__

### add_field(self, name=None, values=None, field_type=None, label=None, options=None, required=False, desc=None, value=None) | source code
Add a field to the form. Parameters: `name` (`unicode`) - field name. `values` (`list` of `unicode`) - raw field values. Not to be used together with `value`. `field_type` (`str`) - field type. `label` (`unicode`) - field label. `options` (`list` of Option) - optional values for the field. `required` (`bool`) - `True` if the field is required. `desc` (`unicode`) - natural-language description of the field. `value` (`bool` for "boolean" field, JID for "jid-single", `list` of JID for "jid-multi", `list` of `unicode` for "list-multi" and "text-multi" and `unicode` for other field types.) - field value or values in a field_type-specific type. May be used only if `values` parameter is not provided. Returns: Field the field added.

### add_item(self, fields=None) | source code
Add and item to the form. Parameters: `fields` (`list` of Field) - fields of the item (they may be added later). Returns: Item the item added.

### make_submit(self, keep_types=False) | source code
Make a "submit" form using data in `self`. Remove uneeded information from the form. The information removed includes: title, instructions, field labels, fixed fields etc. Parameters: `keep_types` (`bool`) - when `True` field type information will be included in the result form. That is usually not needed. Returns: Form the form created. Raises: `ValueError` - when any required field has no value.

### copy(self) | source code
Get a deep copy of `self`. Returns: Form a deep copy of `self`.

### complete_xml_element(self, xmlnode, doc) | source code
Complete the XML node with `self` content. Parameters: `xmlnode` (`libxml2.xmlNode`) - XML node with the element being built. It has already right name and namespace, but no attributes or content. `doc` (`libxml2.xmlDoc`) - document to which the element belongs. Overrides: objects.StanzaPayloadObject.complete_xml_element

### __from_xml(self, xmlnode) | source code
Initialize a Form object from an XML element. Parameters: `xmlnode` (`libxml2.xmlNode`) - the XML element.

### __get_reported(self, xmlnode) | source code
Parse the <reported/> element of the form. Parameters: `xmlnode` (`libxml2.xmlNode`) - the element to parse.
