python 2.7 - Is this a valid structure for voluptuous or am I missing something -

i've yaml file. i've required , optional keys , i've optional blocks, 'linux', 'http' , on.

--- project:     name: lolproj     url: http://wiki.tld/lolproj contact:     name: foobar     email: foobar@gmail.com plugins:     linux:         settings:             disk:                 critical: 90                 warning: 80     http: ... 

i loading , validating way:

from voluptuous import *  def main():      open('mytiny.yaml', 'r') f:         mon = yaml.safe_load(f)      project =  {         required('name'): all(str, length(min=5), msg="must string!"),         required('url'): all(str, length(min=5))     }      contact = {         required('name'): all(str, length(min=5)),         required('email'): all(str, length(min=5)),     }      disk_settings = {             'warning': int,             'critical': int,     }      plugins = ['linux','http','mysql']      schema = schema({         required('project'): project,         required('contact'): contact,         optional('plugins'): plugins,             optional('settings'): {                 optional('disk'): disk_settings,             }     }) 

but getting error:

traceback (most recent call last):   file "./readmon.py", line 143, in <module>     main()   file "./readmon.py", line 43, in main     schema(mon)   file "/usr/local/lib/python2.7/site-packages/voluptuous.py", line 207, in __call__     return self._compiled([], data)   file "/usr/local/lib/python2.7/site-packages/voluptuous.py", line 386, in validate_dict     return base_validate(path, iteritems(data), out)   file "/usr/local/lib/python2.7/site-packages/voluptuous.py", line 287, in validate_mapping     raise multipleinvalid(errors) voluptuous.multipleinvalid: expected list dictionary value @ data['plugins'] 

so, looks i'am doing bad. tip on this? thing is, have like:

['plugins']['linux']['settings']['disk'], or ['plugins']['http']['settings']['disk'] being 'linux'or'http' variables fields optional settings.

voluptuous documentation not newbie friendly :/

just changed yaml layout to

" ...   plugins:     linux:         disk:             critical: 90             warning: 80         exec:             exitcode: 0     http:         url: http://127.0.0.1         port: 8080         status: 200  ... " 

and validated as

''' plugins setup ''' disk_settings = {     optional('critical'): int,     optional('warning'): int,     optional('volume'): str, }  exec_settings = {     optional('exitcode'): int, }  linux_settings = {     optional('disk'): disk_settings,     optional('exec'): exec_settings, }  http_settings = {     optional('url'): str,     optional('port'): int,     optional('status'): int, }  plugins = {     optional('linux'): linux_settings,     optional('http'): http_settings, }   ''' core schema ''' schema = schema({     required('project'): project,     required('contact'): contact,     optional('plugins'): plugins, }) 

it's working :)
