Re: Connecting to a MongoDB Atlas Cluster

Thanks Stef, I really am not technically knowledgeable to answer that question but all documentation is here https://docs.atlas.mongodb.com/tutorial/connect-to-your-cluster/ however after the technicals, i sort of noted somewhere that A database username and password is required in the connect string for a connect and there could be a slight variation in AWS / Azure / GCP hosting (I am using GCP but can change) Thanks for helping StÃ©phane Ducasse wrote > Hi > > what is the authentification protocol of this service? > > S > >> On 25 Mar 2021, at 15:12, Sanjay Minni < > sm@ > > wrote: >> >> Hi All, >> >> I really need some help here as I am unable to connect >> Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. >> (This service gives a free 500 MB MongoDB cluster on the cloud and >> thereafter larger on subscription) >> >> I have got stuck in my application development. >> >> The connection is thru MongoDB (client) Drivers and the connection string >> typically is given as >> 'mongodb+srv:// > <username> > : > <password> > @yyyy.xxxxx.mongodb.net/ > <mydefaultdatabase> > ?retryWrites=true&w=majority" >> >> >> Ques 1.: >> >> is MongoClient required ? >> >> though Atlas service is a cluster the manual for Atlas states >> 'MongoDB drivers automatically attempt server selection following a >> cluster election or failover event.

Re: Connecting to a MongoDB Atlas Cluster

by Sanjay Minni

Hi All, I really need some help here as I am unable to connect Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. (This service gives a free 500 MB MongoDB cluster on the cloud and thereafter larger on subscription) I have got stuck in my application development. The connection is thru MongoDB (client) Drivers and the connection string typically is given as 'mongodb+srv://<username>:<password>@yyyy.xxxxx.mongodb.net/<mydefaultdatabase>?retryWrites=true&w=majority" Ques 1.: is MongoClient required ? though Atlas service is a cluster the manual for Atlas states 'MongoDB drivers automatically attempt server selection following a cluster election or failover event. By default, the C driver immediately raises an error if its first attempt to select a server fails. ...' in any case MongoClient will probably fail in the following line at >>initializeWith: ... initialUrlStrings := initialUrls collect: [:each | each asMongoUrl asMongoUrlString ]. as asMongoUrl will not work with the scheme 'mongodb+srv' Ques 2: Can we directly connect thru class Mongo. However the specified connect string above would not go thru So can someone pls help on how to connect or work around this Sanjay Minni wrote > Hi > > can anyone pls help me with an example of connecting to a MongoDB Atlas > cluster (their cloud service). > > My Atlas cluster replica set is at the urls > yyyy-shard-00-00.xxxxx.mongodb.net:27017 > yyyy-shard-00-01.xxxxx.mongodb.net:27017 > yyyy-shard-00-02.xxxxx.mongodb.net:27017 > > The MongoDB Atlas website specifies the application connectstring as > > > 'mongodb+srv:// > <username> > : > <password> > @yyyy.xxxxx.mongodb.net/ > <mydefaultdatabase> > ?retryWrites=true&w=majority" > > I saw the doc / example on pharo-nosql/mongotalk but could not figure out > in > MongoClient - > > 1. how to get embed the username:password in the connectstring which i > feel > would be needed, > 2. how to specify the default database > 3. is it required to specify all three members while Mongo suggests a > single > part connect string which probably must be covering the cluster > > thanks > > > > > ----- > cheers, > Sanjay > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: Problem installing Seaside on Windows

by JuliÃ¡n Maestri

Before you give up, try this: Install (or reinstall) git from https://git-scm.com/ and make sure to set up the option to use Windows Secure Channel library. [image: image.png] It has solved a lot of issues for me with pharo + git on windows, and not being able to clone via https.

This is indeed step one: make sure that you can check out code from git(hub) on the command line in Windows. Only if that works you can do the next steps.

Re: Problem installing Seaside on Windows

by Sanjay Minni

The error seems wierd, but I am a pure windows user and have not encountered any problem except 1 issue which i will mention below. I dont know what, if any, at all of below will help and its difficult to reproduce / simulate the problem as it may clobber up something else. Logically none of the below are required, though logically you shouldnt be facing any problem either. anyways - first a simple path 1. create a github login - thats all and do remember your ID and password which may be needed later 2. In github click your icon on top right, then go to settings-> SSH and GPG keys and enter your SSH public key, you will find instructions along the way. paste your id_isa.pub file from C:\Users\<you>\.ssh (note: i assume you have generated your ssh key files) 3. save and exit then create a new image thru pharo launcher - ** change image name to a short name ** i.e. change default "Pharo 8.0 - 64bit (stable)" to say "p8my1" or whatever here is a typical windows problem of long file names which aggravates as packages with long names are installed now try to to install iceberg->add->clone github-> seasidest | seaside | | (https or ssh) enter github credentials when asked hope that helps Long Haired David wrote > Tried that.
