How to pass data in object_ptr format in python-telegram library

In python-telegram lib; I have a problem with calling methods which require data in object_ptr data type (You can read about it in tdlib documentation)
Exactly my problem is in addContact method. How should I pass data in params ?
I act like this:
result = t.call_method('addContact',params={'contact' : { 'phone_number' : 'some number' , 'first_name' : 'some name' , 'last_name' : 'some thing' , 'vcard' : '' , 'user_id' : 0 } , 'share_phone_number' : False})
result.wait()
print(result.update)
The print result is None & no contact is added.
Where is the problem?
This links may be useful:
TDLib addContact Class Reference

Finaly I found the solution
I should use importContacts method to add contacts by phone number and without knowing user ID.
Also, printing result.error_info will be useful

I have an Error with python flask cause of an API result (probably cause of my list) and my Database

I use flask, an api and SQLAlchemy with SQLite.
I begin in python and flask and i have problem with the list.
My application work, now i try a news functions.
I need to know if my json informations are in my db.
The function find_current_project_team() get information in the API.
def find_current_project_team():
headers = {"Authorization" : "bearer "+session['token_info']['access_token']}
user = requests.get("https://my.api.com/users/xxxx/", headers = headers)
user = user.json()
ids = [x['id'] for x in user]
return(ids)
I use ids = [x['id'] for x in user] (is the same that) :
ids = []
for x in user:
ids.append(x['id'])
To get ids information. Ids information are id in the api, and i need it.
I have this result :
[2766233, 2766237, 2766256]
I want to check the values ONE by One in my database.
If the values doesn't exist, i want to add it.
If one or all values exists, I want to check and return "impossible sorry, the ids already exists".
For that I write a new function:
def test():
test = find_current_project_team()
for find_team in test:
find_team_db = User.query.filter_by(
login=session['login'], project_session=test
).first()
I have absolutely no idea to how check values one by one.
If someone can help me, thanks you :)
Actually I have this error :
sqlalchemy.exc.InterfaceError: (InterfaceError) Error binding
parameter 1 - probably unsupported type. 'SELECT user.id AS user_id,
user.login AS user_login, user.project_session AS user_project_session
\nFROM user \nWHERE user.login = ? AND user.project_session = ?\n
LIMIT ? OFFSET ?' ('my_tab_login', [2766233, 2766237, 2766256], 1, 0)

It looks to me like you are passing the list directly into the database query:
def test():
test = find_current_project_team()
for find_team in test:
find_team_db = User.query.filter_by(login=session['login'], project_session=test).first()
Instead, you should pass in the ID only:
def test():
test = find_current_project_team()
for find_team in test:
find_team_db = User.query.filter_by(login=session['login'], project_session=find_team).first()
Asides that, I think you can do better with the naming conventions though:
def test():
project_teams = find_current_project_team()
for project_team in project_teams:
project_team_result = User.query.filter_by(login=session['login'], project_session=project_team).first()

All works thanks
My code :
project_teams = find_current_project_team()
for project_team in project_teams:
project_team_result = User.query.filter_by(project_session=project_team).first()
print(project_team_result)
if project_team_result is not None:
print("not none")
else:
project_team_result = User(login=session['login'], project_session=project_team)
db.session.add(project_team_result)
db.session.commit()

Search for a dynamic field in a mongodb collection

If I were to search for a particular field in a mongodb collection my command would look something like this :
db.collection.find({ name : "John"})
If I want to make the field name dynamic, what would the command be?
Example:
db.collection.find({ <Dyanmic field variable> : <Value>})
Or is there an alternative to achieve this function?

Just use the variable in place of the dictionary key:
name = 'field_name'
db.collection.find({name : "John"})

Problem happens when you try without knowing data type. So in order to handle this , i used the following:
def multi_row_single_field_update(self, crieteriafldnm, crieteriafldtyp, updtfldnm, updtfldval, updtfldtyp):
try:
criteria = raw_input('\nEnter ' + crieteriafldnm + ' to update\n')
if crieteriafldtyp == 'int':
count = self.my_connect.find({str(crieteriafldnm): int(criteria)}).count()
else:
count = self.my_connect.find({str(crieteriafldnm): str(criteria)}).count()
updt_criteria = int(criteria) if updtfldtyp == 'int' else str(criteria)
self.my_connect.update(
{"$atomic": 1},
{str(crieteriafldnm): updt_criteria},
{"$set": {str(updtfldnm): str(updtfldval)}},
upsert=False, multi=True
)

ElasticSearch and Python - Correct methodolgy

I am building a search engine for the list of articles I have. I was advised by a lot of people to use elastic search for full text search. I wrote the following code. It works. But I have a few issues.
1) If the same article is added twice - that is indexdoc is run twice for the same article, it accepts it and adds the article twice. Is there a way to have a "unique key" in the search index.
2) How can I change the scoring / ranking function? I want to give more importance to title?
3) Is this the correct way to do it anyways?
4) How do I show related results - if there is a spelling mistake?
from elasticsearch import Elasticsearch
from crsq.models import ArticleInfo
es = Elasticsearch()
def indexdoc(articledict):
doc = {
'text': articledict['articlecontent'],
'title' : articledict['articletitle'],
'url': articledict['url']
}
res = es.index(index="article-index", doc_type='article', body=doc)
def searchdoc(keywordstr):
res = es.search(index="article-index", body={"query": {"query_string": {"query": keywordstr}}})
print("Got %d Hits:" % res['hits']['total'])
for hit in res['hits']['hits']:
print("%(url)s: %(text)s" % hit["_source"])
def indexurl(url):
articledict = ArticleInfo.objects.filter(url=url).values()
if len(articledict):
indexdoc(articledict)
return

1) You have to specify an id for you document. You have to add the parameter id when you are indexing
res = es.index(index="article-index", doc_type='article', body=doc, id="some_unique_id")
2) There is more than one way to do this, but for example you can boost title by changing a bit your query:
{"query": {"query_string": {"query": keywordstr, "fields" : ["text", "title^2"]}}
With this change title will have the double of importance that field text
3) As a proof of concept is not bad.
4) This is a big topic, I think you should check the documentation of suggesters

Mongoengine, retriving only some of a MapField

For Example.. In Mongodb..
> db.test.findOne({}, {'mapField.FREE':1})
{
"_id" : ObjectId("4fb7b248c450190a2000006a"),
"mapField" : {
"BOXFLUX" : {
"a" : "f",
}
}
}
The 'mapField' field is made of MapField of Mongoengine.
and 'mapField' field has a log of key and data.. but I just retrieved only 'BOXFLUX'..
this query is not working in MongoEngine....
for example..
BoxfluxDocument.objects( ~~ querying ~~ ).only('mapField.BOXFLUX')
AS you can see..
only('mapField.BOXFLUX') or only only('mapField__BOXFLUX') does not work.
it retrieves all 'mapField' data, including 'BOXFLUX' one..
How can I retrieve only a field of MapField???

I see there is a ticket for this: https://github.com/hmarr/mongoengine/issues/508
Works for me heres an example test case:
def test_only_with_mapfields(self):
class BlogPost(Document):
content = StringField()
author = MapField(field=StringField())
BlogPost.drop_collection()
post = BlogPost(content='Had a good coffee today...',
author={'name': "Ross", "age": "20"}).save()
obj = BlogPost.objects.only('author__name',).get()
self.assertEquals(obj.author['name'], "Ross")
self.assertEquals(obj.author.get("age", None), None)

Try this:
query = BlogPost.objects({your: query})
if name:
query = query.only('author__'+name)
else:
query = query.only('author')

I found my fault! I used only twice.
For example:
BlogPost.objects.only('author').only('author__name')
I spent a whole day finding out what is wrong with Mongoengine.
So my wrong conclusion was:
BlogPost.objects()._collection.find_one(~~ filtering query ~~, {'author.'+ name:1})
But as you know it's a just raw data not a mongoengine query.
After this code, I cannot run any mongoengine methods.
In my case, I should have to query depending on some conditions.
so it will be great that 'only' method overwrites 'only' methods written before.. In my humble opinion.
I hope this feature would be integrated with next version. Right now, I have to code duplicate code:
not this code:
query = BlogPost.objects()
query( query~~).only('author')
if name:
query = query.only('author__'+name)
This code:
query = BlogPost.objects()
query( query~~).only('author')
if name:
query = BlogPost.objects().only('author__'+name)
So I think the second one looks dirtier than first one.
of course, the first code shows you all the data
using only('author') not only('author__name')
