I want to use weaviate as a database for haystack
using:
from haystack.document_store import WeaviateDocumentStore
document_store = WeaviateDocumentStore(port= "", host="", username="", password="", index="document")
But each time it creates a new class. How can I connect to an already available class/schema?
Also write_documents is does not work..
document_store.write_documents([docs])
Any suggestions?

I would like SQLAlchemy to return an error if the underlying SQLite3 database file does not exist.
I've looked around, and tried:
#!/usr/bin/env python3
from sqlalchemy import create_engine, Column, Integer
from sqlalchemy.orm import Session, declarative_base
Base = declarative_base()
class SomeTable(Base):
id = Column(Integer)
DB_SPECIFIER = 'sqlite+pysqlite:////tmp/non-exist.db?mode=rw'
engine = create_engine(DB_SPECIFIER, echo=False, future=True, connect_args={'uri': True})
session = Session(engine)
x = session.query(SomeTable)
I'd like the create_engine call to fail if /tmp/non-exist.db does not exist. I thought using this answer would work, but it did not.
Looks like it's in the docs, though fairly hidden:
https://docs.sqlalchemy.org/en/14/dialects/sqlite.html#uri-connections
So you'd do:
DB_SPECIFIER = 'sqlite:///file:/tmp/non-exist.db?mode=ro&uri=true'
engine = create_engine(DB_SPECIFIER, echo=False, future=True)
It picks this apart and sends arguments to the connection, the rest through to the URI. (You can also add some lock disabling and such there, if that helps, since it's read only).
attribute itemJson stored as follow
"itemJson": {
"S": "{\"sold\":\"3\",\"listingTime\":\"20210107211621\",\"listCountry\":\"US\",\"sellerCountry\":\"US\",\"currentPrice\":\"44.86\",\"updateTime\":\"20210302092220\",\"itemLocation\":\"Miami,FL,USA\",\"listType\":\"FixedPrice\",\"categoryName\":\"Machines\",\"itemID\":\"293945109477\",\"sellerID\":\"holiday_for_you\",\"s3Key\":\"US/2021/2/FixedPrice/293945109477.json\",\"visitCount\":\"171\",\"createTime\":\"20210201233158\",\"listingStatus\":\"Completed\",\"endTime\":\"2021-02-28T20:22:57\",\"currencyID\":\"USD\"}"
},
i want to query with filter:contains(itemJson, "sold":"0") with java sdk,i tried those syntax,all fail
expressionValues.put(":v2", AttributeValue.builder().s("\\\"sold\\\":\\\"0\\\"").build());
expressionValues.put(":v2", AttributeValue.builder().s("sold:0"").build());
what is the right way to my filter syntax?
I try #Balu Vyamajala's syntax on the dynamodb web console as follow,did not get the solution yet
contains (itemJson, :subValue) with value of "sold\":\"3\"" seems to be working.
Working example on a Query Api and worked as expected:
QuerySpec querySpec = new QuerySpec()
.withKeyConditionExpression("pk = :v_pk")
.withFilterExpression("contains (itemJson, :subValue)")
.withValueMap(new ValueMap().withString(":v_pk", "6").withString(":subValue", "sold\":\"3\""));
and to test from Aws console we just need to enter "sold":"2"
I'm trying to write a quick script to open a family document, change the parameter group of 2 specified parameters, and then close and save the document. I've done multiple tests and I am able to change the parameter groups of the specified parameters, but the changes of the groups don't save back to the family file. When I open the newly saved family, the parameter groups revert back to their original group.
This is with Revit 2017.2.
The same script, when run in RPS in Revit 2018 will do as desired.
import clr
import os
clr.AddReference('RevitAPI')
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import UIApplication
from System.IO import Directory, SearchOption
searchstring = "*.rfa"
dir = r"C:\Users\dboghean\Desktop\vanity\2017"
docs = []
if Directory.Exists(dir):
files = Directory.GetFiles(dir, searchstring, SearchOption.AllDirectories)
for f in files:
name, extension = os.path.splitext(f)
name2, extension2 = os.path.splitext(name)
if extension2:
os.remove(f)
else:
docs.append(f)
else:
print("Directory does not exist")
doc = __revit__.ActiveUIDocument.Document
app = __revit__.Application
uiapp = UIApplication(app)
currentPath = doc.PathName
pgGroup = BuiltInParameterGroup.PG_GRAPHICS
for i in docs:
doc = app.OpenDocumentFile(i)
paramList = [i for i in doc.FamilyManager.Parameters]
t = Transaction(doc, "test")
t.Start()
for i in paramList:
if i.Definition.Name in ["Right Sidesplash Edge line", "Left Sidesplash Edge line"]:
i.Definition.ParameterGroup = pgGroup
t.Commit()
doc.Close(True)
Any ideas?
Thanks!
I can confirm that this happens in Revit 2017. Strange!
A simple way around it is to arbitrarily rename the parameter using doc.FamilyManager.RenameParameter, then rename it back to the original name.
So in your case this would be three additional lines of code after changing the Parameter group:
originalName = i.Definition.Name
doc.FamilyManager.RenameParameter(i, "temp")
doc.FamilyManager.RenameParameter(i, originalName)
Doesnt get to the root problem, but works around it
I am doing a project in Python, django rest framework. I am using haystack SearchQuerySet. My code is here.
from haystack import indexes
from Medications.models import Salt
class Salt_Index(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
name = indexes.CharField(model_attr='name',null=True)
slug = indexes.CharField(model_attr='slug',null=True)
if_i_forget = indexes.CharField(model_attr='if_i_forget',null=True)
other_information = indexes.CharField(model_attr='other_information',null=True)
precautions = indexes.CharField(model_attr='precautions',null=True)
special_dietary = indexes.CharField(model_attr='special_dietary',null=True)
brand = indexes.CharField(model_attr='brand',null=True)
why = indexes.CharField(model_attr='why',null=True)
storage_conditions = indexes.CharField(model_attr='storage_conditions',null=True)
side_effects = indexes.CharField(model_attr='side_effects',null=True)
def get_model(self):
return Salt
def index_queryset(self, using=None):
return self.get_model().objects.all()
and my views.py file is -
from django.views.generic import View
from haystack.query import SearchQuerySet
from django.core import serializers
class Medication_Search_View(View):
def get(self,request,format=None):
try:
get_data = SearchQuerySet().all()
print get_data
serialized = ss.serialize("json", [data.object for data in get_data])
return HttpResponse(serialized)
except Exception,e:
print e
my python manage.py rebuild_index is working fine (showing 'Indexing 2959 salts') but in my 'views.py' file , SearchQuerySet() is returning an empty query set...
I am very much worried for this. Please help me friends if you know the reason behind getting empty query set while I have data in my Salt model.
you should check app name it is case sensitive.try to write app name in small letters
My problem is solved now. The problem was that i had wriiten apps name with capital letters and the database tables were made in small letters(myapp_Student). so it was creating problem on database lookup.
I'm having trouble retrieving a filtered list from google app engine datastore (using python for server side). My data entity is defined as the following
class Course_Table(db.Model):
course_name = db.StringProperty(required=True, indexed=True)
....
head_tags_1=db.ListProperty(db.Key)
So the head_tags_1 property is a list of keys (which are the keys to a different entity called Headings_1).
I'm in the Handler below to spin through my Course_Table entity to filter the courses that have a particular Headings_1 key as a member of the head_tags_1 property. However, it doesn't seem like it is retrieving anything when I know there is data there to fulfill the request since it never displays the logs below when I go back to iterate through the results of my query (below). Any ideas of what I'm doing wrong?
def get(self,level_num,h_key):
path = []
if level_num == "1":
q = Course_Table.all().filter("head_tags_1 =", h_key)
for each in q:
logging.info('going through courses with this heading name')
logging.info("course name filtered is %s ", each.course_name)
MANY MANY THANK YOUS
I assume h_key is key of headings_1, since head_tags_1 is a list, I believe what you need is IN operator. https://developers.google.com/appengine/docs/python/datastore/queries
Note: your indentation inside the for loop does not seem correct.
My bad apparently '=' for list is already check membership. Using = to check membership is working for me, can you make sure h_key is really a datastore key class?
Here is my example, the first get produces result, where the 2nd one is not
