                           SQLFORM


SQLFORM is used to map a table (and a current record) into an HTML form

given a SQLTable stored in db.table

generates an insert form::

    SQLFORM(db.table)

generates an update form::

    record=db.table[some_id]
    SQLFORM(db.table, record)

generates an update with a delete button::

    SQLFORM(db.table, record, deletable=True)

if record is an int::

    record=db.table[record]

optional arguments:

:param fields: a list of fields that should be placed in the form,
    default is all.
:param labels: a dictionary with labels for each field, keys are the field
    names.
:param col3: a dictionary with content for an optional third column
        (right of each field). keys are field names.
:param linkto: the URL of a controller/function to access referencedby
    records
        see controller appadmin.py for examples
:param upload: the URL of a controller/function to download an uploaded file
        see controller appadmin.py for examples

any named optional attribute is passed to the <form> tag
        for example _class, _id, _style, _action, _method, etc.

source code


similar FORM.accepts but also does insert, update or delete in DAL.
but if detect_record_change == True than:
  form.record_changed = False (record is properly validated/submitted)
  form.record_changed = True (record cannot be submitted because changed)
elseif detect_record_change == False than:
  form.record_changed = None

Overrides: html.FORM.accepts

factory(*fields, **attributes)
Static Method

source code

generates a SQLFORM for the given fields.

Internally will build a non-database based data model to hold the fields.

smartgrid(table, constraints=global_settings.applications_parent, linked_tables=global_settings.applications_parent, links=global_settings.applications_parent, links_in_grid=True, args=global_settings.applications_parent, user_signature=True, **kwargs)
Static Method

source code


@auth.requires_login()
def index():
    db.define_table('person',Field('name'),format='%(name)s')
    db.define_table('dog',
        Field('name'),Field('owner',db.person),format='%(name)s')
    db.define_table('comment',Field('body'),Field('dog',db.dog))
    if db(db.person).isempty():
        from gluon.contrib.populate import populate
        populate(db.person,300)
        populate(db.dog,300)
        populate(db.comment,1000)
        db.commit()
form=SQLFORM.smartgrid(db[request.args(0) or 'person']) #***
return dict(form=form)

*** builds a complete interface to navigate all tables links
    to the request.args(0)
    table: pagination, search, view, edit, delete,
           children, parent, etc.

constraints is a dict {'table',query} that limits which
records can be accessible
links is a dict like
   {'tablename':[lambda row: A(....), ...]}
that will add buttons when table tablename is displayed
linked_tables is a optional list of tablenames of tables
to be linked
