i install the meteor package and within is the mongoDB. Now I made an easy application and create a mongo db collection ...
Todos = new Mongo.Collection('todos');
I write data in this collection and everything works fine. BUT! I can not find the mongodb and the collections an my Mac?! I read on some sites that I have to watch at /data/db but on my mac there is not such a file...
Can anyone explain where mongoDb takes the data on my Mac.
Thank you
Countless duplicates to this one if you use the search engine, but a short answer would be to look inside: .meteor/local/db

just starting testcontainers. I love the idea. thanks for investing in this project.
I am trying to create a simple postgres 14.5 container (and susceeded) and now I am trying to populate it using the .withInitScript() method.
the file I am feeding into the init method is a dump I created with pg_dumpall.
testcontainers fails for many parsing/validation reasons. each time I delete a portion and another reason pops up.
should I be able to succesfully use the withInitScript with pg_dump files?
BTW, using pg_dump for my main DB also has many similar issues.
thanks!
Try copying the script to the container so postgres will execute. Although this comment BTW, using pg_dump for my main DB also has many similar issues. makes me wonder if it will work because it also fails when you are using the database directly if I understood correctly.
new PostgreSQLContainer("postgres:14.5")
.withCopyFileToContainer(
MountableFile.forClasspathResource("init.sql"),
"/docker-entrypoint-initdb.d/init.sql"
);
We recommend to use liquibase or flyway to manage database changes.
hi and thanks for the help
I have managed to make things work by stripping some things from the sql dump and using the copyFileToContainer
thanks
I'm attempting to write a simple Ruby/Nokogiri scraper to get event information from multiple pages and then output it to a CSV that is attached to an email sent out weekly.
I have completed the scraping components and the CSV component and it's working perfectly. However, I now realize that I need to know when new events are added, which means I need some sort of database. Ideally I would just store this locally.
I've dabbled a bit with using the ruby gem 'sequel', but the data does not seem to persist beyond the running of the program. Do I need to download some database software to work with 'sequel'? Also I'm not using the Rails framework, just Ruby.
Any and all guidance is deeply appreciated!
I'm guessing you did Sequel.sqlite, as in the first example in the Sequel README, which creates an in-memory SQLite database. To create a database in your filesystem instead of memory, just pass it a path, e.g.:
Sequel.sqlite("./my-database.db")
This is, of course, assuming that you have the sqlite3 gem installed. If the given file doesn't exist, it will be created.
This is covered in the Sequel docs.
Good Day.
I've been developing with meteorJS which uses mongodb. No problems there. I've been using the mongo shell to access the database on my dev machine (osx 10.11). This is my first project with mongo and when the shell would load, it would connect to db.test and I'd always show dbs and get the list of database, then use myApp.
Yesterday whenever I go into the shell and I type show dbs the only one shown is local 0.078GB. However my app is still working and pulling and pushing data to the database.
I've checked the dbpath in the mongod.conf and that seems ok. I'm not entirely sure about the exact order of things, but two things where different (I'm not sure if these happened prior to the show dbs not showing everything or after, and I'm not sure which came first):
when loading the mongo shell I was getting this error:
WARNING: soft rlimits too low. Number of files is 256, should be at least 1000"
I followed these directions which seemed to stop that error from appearing (https://github.com/basho/basho_docs/issues/1402 )
I use Meteor Toys and for the first time I update user.profile.companyName (which is a custom field within the standard profile from within the Meteor Toys widget.
Just odd that the app can still access the database and collections, but that the mongo shell doesn't show. I've update mongod via brew upgrade mongodb from 3.0.2 to 3.0.7 to no avail.
Any ideas?
If you want to use the regular mongo console you have to specify the port to be 3001 for meteor apps instead of the default 27017. Otherwise it's much simpler to just type meteor mongo and connect that way. Then you can type 'show collections' and it will show them all just like normal.
MongoDB do not show the database unless if there is minimum of one collection with a document in it.

I am trying to created a Thinkaurelius titan datastore using:
TitanGraph graph = TitanFactory.open("/tmp/graph")
The documentation can be found at https://github.com/thinkaurelius/titan/wiki/Using-BerkeleyDB
But each time I open the graph a new datastore is being created. I even tryed using the configure object but it did not help. Has any one worked on this before? I wanto create a titan datastore that should be reusable, i.e. it should not create a new datastore each time I open it.
Any suggestions please?
It sounds like the changes aren't being committed to the database. Look more into how transactions work.

I've been using MongoDB for a little tool that I'm building, but I have two problems that I don't know if I can "solve". Those problems are mainly related with having to start a MongoDB server (mongod).
The first is that I have to run two commands every time that I want to use it (mongod and my app's command) and the other is testing. For now, I'm using different collections for "production" and "test", but it would be better to have just an embedded / self-contained instance that I can start and drop whenever I want.
Is that possible? Or should I just use something else, like SQLite for that?
Thanks!
Another similar project is https://github.com/Softmotions/ejdb.
The query syntax is similar to mongodb.
We use this at work - https://github.com/flapdoodle-oss/embedmongo.flapdoodle.de - to fire up embedded Mongo for integration tests. Has worked really well.
I haven't tried it, but I just found this Ruby implementation of an embedded MongoDB: https://github.com/gdb/embedded-mongo
