I'm experimenting with the various field types (mysql) to learn more about
web2py.
I'm not sure why I got this error
<type 'exceptions.AttributeError'> 'str' object has no attribute 'writable'
Version
web2py(tm) Version 2.9.5-trunk+timestamp.2014.07.03.12.21.52
Given this table:
db.define_table('test_all_fields',
Field('f1_boolean','boolean'),
Field('f1a_string'),
Field('f2_text','text'),
Field('f3_json','json'),
Field('f4_password','password'),
Field('f5_blob','blob'),
Field('f6_upload','upload'),
Field('f7_integer','integer'),
Field('f8_bigint','bigint'),
Field('f10_double','double'),
Field('f11_decimal','decimal(8,2)'),
Field('f12_date','date'),
Field('f13_time','time'),
Field('f14_datetime','datetime'),
#Field('f15_list_integer','list:integer'),
#Field('f16_list_string','list:string'),
)
I wanted to display a record from it using SQLFORM, with all defaults:
row=db.test_all_fields(request.args[1])
form=SQLFORM(row)
The error is being thrown in gluon/sqlhtml.py, line 1037:
Aren't the default attributes for a Field maintained throughout?
Thanks!!
