Shouldn't it permit passing/posting multiple items for a list-type field? about cerberus HOT 11 CLOSED

Try:

tels: {
  'type': 'list', 
  'items': {
      'text': {'type': 'string', 'required': True},
      'ext': {'type': 'string'},
      'note': {'type': 'string', 'maxlength': 64}
  }}

From the docs: "When a dictionary, items defines the validation schema for items in a list (...) When a list, defines the allowed values for a list of fixed length".

Please note that in order to make list validation easier, with next release schema is used for both fixed and arbitrary length lists (docs are updated already).

WIll fix the typo.

Ok, I made that change and likely because current release doesn't support it yet, I returns the error:

"'str' object has no attribute 'get'"

Should I wait for your next release or look/hack a work-around?

Thank you for your excellent support of these projects!!! :)

I updated the snippet, should be ok now. Sorry about that.

I plan on releasing the next version of Cerberus next week, even though it will be a little longer before the next production release of Eve will be available.

LOL had to edit it once again. Time to take break I guess :)

Which scenario do you recommend from the list of three involving the validating of an arbitrary list of dictionaries?

from cerberus.

OK, this passes on a single item, NOT multiple items:

tels = {
    'type': 'list', 
    'items': [{
        'type': 'dict', 
        'schema': {
            'text': {'type': 'string', 'required': True},
            'ext': {'type': 'string'},
            'note': {'type': 'string', 'maxlength': 64}
        }}]}

Check my snippet again (didn't get it right the first time around). The schema thing won't work with the current version (0.0.2) of Cerberus.

I think you are referring to the readthedocs snippet.

This does NOT pass:

tels = {
    'type': 'list', 
    'schema': {
        'type': 'dict', 
            'schema': {
                'text': {'type': 'string', 'required': True},
                'ext': {'type': 'string'},
                'note': {'type': 'string', 'maxlength': 64}
        }}}

This PASSES:

tels = {
    'type': 'list', 
    'items': {
            'text': {'type': 'string', 'required': True},
            'ext': {'type': 'string'},
            'note': {'type': 'string', 'maxlength': 64}
        }}

AND this PASSES:

tels = {
    'type': 'list', 
    'items': [{
        'type': 'dict', 
        'schema': {
            'text': {'type': 'string', 'required': True},
            'ext': {'type': 'string'},
            'note': {'type': 'string', 'maxlength': 64}
        }}]}

In cases that pass, it is only when validating against ONE item.

Am in a hurry now, however I quickly tested the following and it seems to behave correctly:

>>> from cerberus import Validator
>>> v = Validator()
>>> schema = {'tels': {'type': 'list', 'items': {'text': {'type': 'string'}, 'num': {'type': 'integer'}}}}
>>> document = {'tels': [{'text': 'hello', 'num': 1}, {'text': 'bye'}]}
>>> v.validate(document, schema)
True

Hope this helps.

from cerberus.

Awesome!! It worked AND I was able to validate more than one list item. :)

I occurs to me that if/when a list item fails, how would you know WHICH item in the list failed? Would it help to return the offending item with the error? I don't even see an offset pointing to the position in the list.

from cerberus.

That's probably a good idea. Would you open ticket/issue for that?
