Can you help me to convert following code so that will work for choiceblock in wagtail
YEAR_CHOICES = []
for r in range(1999, (datetime.now().year+1)):
YEAR_CHOICES.append((r,r))
class Spieler(StructBlock):
jahrgang = ChoiceBlock(_('year'), max_length=4, choices=YEAR_CHOICES, default=datetime.now().year)
at the moment I have the following error
File "C:\Users\xakep\GitHub\treichle_cup\team_rooster\models.py", line 31, in <module>
class Spieler(StructBlock):
File "C:\Users\xakep\GitHub\treichle_cup\team_rooster\models.py", line 37, in Spieler
jahrgang = ChoiceBlock(_('year'), max_length=4, choices=YEAR_CHOICES, default=datetime.now().year)
TypeError: __init__() got multiple values for argument 'choices'
_('year') should be passed as label=_('year'):
jahrgang = ChoiceBlock(label=_('year'), max_length=4, choices=YEAR_CHOICES, default=datetime.now().year)
ChoiceBlock only accepts named arguments - if you leave out the name, it'll think that you're passing a choices value instead.

[DISCORD.PY and TINYDB]
I have set up a warning system for Discord. If someone gets warned, the data is saved like so:
{'userid': 264452325945376768, 'warnid': 37996302, 'reason': "some reason"}
Problem of this: I want the command "!warnings" to display these warnings, but I don't want it to have this ugly formatting of a JSON, instead I want it to display like so:
{member} has {amount} warnings.
WARN-ID: {warning id here}
REASON: {reason here}
To do this, I need to somehow call only one variable at a time instead of having all 3 (as of above JSON) instantly.
My code is as follows:
#Ralf.command()
async def warnings(ctx, *, member: discord.Member=None):
if member is None:
member = Ralf.get_user(ctx.author.id)
member_id = ctx.author.id
else:
member = Ralf.get_user(member.id)
member_id = member.id
WarnList = Query()
Result = warndb.search(WarnList.userid == member_id)
warnAmt = len(Result)
if warnAmt == 1:
await ctx.send(f"**{member}** has `{warnAmt}` warning.")
else:
await ctx.send(f"**{member}** has `{warnAmt}` warnings.")
for item in Result:
await ctx.send(item)
This code is working, but it shows the ugly {'userid': 264452325945376768, 'warnid': 37996302, 'reason': "some reason"} as output.
MAIN QUESTION: How do I call only userid without having warnid and reason displayed?
EDIT 1:
Trying to use dicts results in following:
For that I get the following:
Ignoring exception in command warnings:
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

You are getting the TypeError because your Result is a list of dictionaries.
Make sure to iterate through Result and process each dictionary separately.
Your Result object is like this [{}, {}, {} ...]
Also you shouldn't capitalize the first letter of your variable. You should name it results, because it may contain more than 1 result.
for item in results:
user_id = item.get("userid")
warn_id = item.get("warnid")
reason = item.get("reason")
# do stuff with those
hi all ijson newbie I have a very large .json file 168 (GB) I want to get all possible keys, but in the file some values are written as NaN. ijson creates a generator and outputs dictionaries, in My code value. When a specific item is returned, it throws an error. How can you get a string instead of a dictionary instead of value? Tried **parser = ijson.items (input_file, '', multiple_values = True, map_type = str) **, didn't help.
def parse_json(json_filename):
with open('max_data_error.txt', 'w') as outfile:

parser = ijson.items(input_file, '', multiple_values=True)

max_keys_list = list()

if i not in max_keys_list:
max_keys_list.append(i)
print(value)
print(max_keys_list)
for keys_item in max_keys_list:
outfile.write(keys_item + '\n')

Your file I not valid JSON (NaN is not a valid JSON value); therefore any JSON parsing library will complain about this, one way or another, unless they have an extension to handle this non-standard content.
The ijson FAQ found in the project description has a question about invalid UTF-8 characters and how to deal with them. Those same answers apply here, so I would suggest you go and try one of those.
Others have reported a similar error, but the solutions given do not solve my problem.
For example there is a good answer here. The answer in the link mentions how ndb changes from a first use to a later use and suggests there is a problem because a first run produces a None in the Datastore. I cannot reproduce or see that happening in the Datastore for my sdk, but that may be because I am running it here from the interactive console.
I am pretty sure I got an initial good run with the GAE interactive console, but every run since then has failed with the error in my Title to this question.
I have left the print statements in the following code because they show good results and assure me that the error is occuring in the put() at the very end.
from google.appengine.ext import ndb
class Account(ndb.Model):
week = ndb.IntegerProperty(repeated=True)
weeksNS = ndb.IntegerProperty(repeated=True)
weeksEW = ndb.IntegerProperty(repeated=True)
terry=Account(week=[],weeksNS=[],weeksEW=[])
terry_key=terry.put()
terry = terry_key.get()
print terry
for t in list(range(4)): #just dummy input, but like real input
terry.week.append(t)
print terry.week
region = 1 #same error message for region = 0
if region :
terry.weeksEW.append(terry.week)
else:
terry.weeksNS.append(terry.week)
print 'EW'+str(terry.weeksEW)
print 'NS'+str(terry.weeksNS)
terry.week = []
print 'week'+str(terry.week)
terry.put()
The idea of my code is to first build up the terry.week list values incrementally and then later store the whole list to the appropriate region, either NS or EW. So I'm looking for a workaround for this scheme.
The error message is likely of no value but I am reproducing it here.

BadValueError: Expected integer, got [0, 1, 2, 3]
I believe the error comes from these lines:
terry.weeksEW.append(terry.week)
terry.weeksNS.append(terry.week)
You are not appending another integer; You are appending a list, when an integer is expected.
>>> aaa = [1,2,3]
>>> bbb = [4,5,6]
>>> aaa.append(bbb)
>>> aaa
[1, 2, 3, [4, 5, 6]]
>>>
This fails the ndb.IntegerProperty test.
Try:
terry.weeksEW += terry.week
terry.weeksNS += terry.week
EDIT: To save a list of lists, do not use the IntegerProperty(), but instead the JsonProperty(). Better still, the ndb datastore is deprecated, so... I recommend Firestore, which uses JSON objects by default. At least use Cloud Datastore, or Cloud NDB.
Suppose I create a key from user input websafe url
key = ndb.Key(urlsafe=some_user_input)
How can I check if the some_user_input is valid?
My current experiment shows that statement above will throw ProtocolBufferDecodeError (Unable to merge from string.) exception if the some_user_input is invalid, but could not find anything about this from the API. Could someone kindly confirm this, and point me some better way for user input validity checking instead of catching the exception?
Thanks a lot!
If you try to construct a Key with an invalid urlsafe parameter
key = ndb.Key(urlsafe='bogus123')
you will get an error like

Interesting here are is
File "/opt/google/google_appengine/google/appengine/ext/ndb/key.py", line 773, in _ReferenceFromSerialized
return entity_pb.Reference(serialized)
which is the last code executed in the key.py module:
def _ReferenceFromSerialized(serialized):
"""Construct a Reference from a serialized Reference."""
if not isinstance(serialized, basestring):
raise TypeError('serialized must be a string; received %r' % serialized)
elif isinstance(serialized, unicode):
serialized = serialized.encode('utf8')
return entity_pb.Reference(serialized)
serialized here being the decoded urlsafe string, you can read more about it in the link to the source code.
another interesting one is the last one:
File "/opt/google/google_appengine/google/appengine/datastore/entity_pb.py", line 1839, in TryMerge
in the entity_pb.py module which looks like this
def TryMerge(self, d):
while d.avail() > 0:
tt = d.getVarInt32()
if tt == 106:
self.set_app(d.getPrefixedString())
continue
if tt == 114:
length = d.getVarInt32()
tmp = ProtocolBuffer.Decoder(d.buffer(), d.pos(), d.pos() + length)
d.skip(length)
self.mutable_path().TryMerge(tmp)
continue
if tt == 162:
self.set_name_space(d.getPrefixedString())
continue
if (tt == 0): raise ProtocolBuffer.ProtocolBufferDecodeError
d.skipData(tt)
which is where the actual attempt to 'merge the input to into a Key' is made.
You can see in the source code that during the process of constructing a Key from an urlsafe parameter not a whole lot can go wrong. First it checks if the input is a string and if it's not, a TypeError is raised, if it is but it's not 'valid', indeed a ProtocolBufferDecodeError is raised.
My current experiment shows that statement above will throw ProtocolBufferDecodeError (Unable to merge from string.) exception if the some_user_input is invalid, but could not find anything about this from the API. Could someone kindly confirm this
Sort of confirmed - we now know that also TypeError can be raised.
and point me some better way for user input validity checking instead of catching the exception?
This is an excellent way to check validity! Why do the checks yourself if the they are already done by appengine? A code snippet could look like this (not working code, just an example)
def get(self):
# first, fetch the user_input from somewhere
try:
key = ndb.Key(urlsafe=user_input)
except TypeError:
return 'Sorry, only string is allowed as urlsafe input'
except ProtocolBufferDecodeError:
return 'Sorry, the urlsafe string seems to be invalid'
I have been searching through solutions to this error, but for everyone else it seems to be caused by a slightly different reason. I have a models.py that looks something like the following:
class MyModel(models.Model):
something1 = models.IntegerField()
something2 = models.CharField(max_length=256)
something3 = models.CharField(max_length=256)
class MyModelForm(ModelForm):
class Meta:
model = MyModel
fields = ('something1', 'something2',)
Say I don't actually want to use 'something3' anymore. If I delete it, and even delete and re-sync the database, I get an error saying
Unknown field(s) (something3) specified for MyModel.
This happens, as far as I have noticed, when I save anything using
saveThis = MyModel(something1=x, something2=y)
saveThis.save()
Any ideas what is throwing this error? I have even done a search through all documents to make sure 'something3' is not in any of them. Here is the traceback:
