It's my first time using Geddy JS and I'm starting to like it but when I tried using sqlite for development db I keep getting Model adapter not found for Page. Set .adapter for this model, or set model.defaultAdapter when I run geddy jake db:init / migrate.
Thanks
Sqlite3 support is very new. In fact, I don't think it's even on NPM yet because #mde was just working on it today.
For updates on this feature you can hop on the #geddy freenode IRC channel, or join our mailing list.
We also have a filesystem adapter that might already be on NPM. If it isn't, it should be soon.

I went through Flyway documentation and did not found the TimescaleDB in the supported databases.
Can anyone confirm if Flyway supports TimescaleDB. If not, is there any other CI/CD tool for TimescaleDB?
We haven't formally tested Flyway on TimescaleDB, but it appears that people have successfully used it (as it's essentially an extension of Postgres). The normal Postgres JDBC connection url should work - and if you have problems, submit an issue at http://github.com/flyway/flyway
I have a website solution that uses on SQLite database for each tenant account. Without going into much depth about why we chose this solution, we chose it due to SQLite support on distributed/offline systems.
All databases are manipulated using the same PHP file structure. I wish to update the database version iteratively for all accounts so that they are all at the same version number.
I have a script that loops over each, and can use either PHP(Yii) or the shell to execute queries.
I would like to wrap the manipulation to each database in a transaction. It appears as though DDL commands may already be auto-commit in nature.
Question: How to accomplish a SQLite DB upgrade which, if it fails, will report a failure? Using that report, I could prompt the system to re-attempt or report an error to an admin. Ideally, I would like to wrap the whole upgrade in a transaction to prevent inconsistencies, but I'm fairly certain that this is not possible.
One thought I had was to backup the database temporarily during upgrade, and delete it on success.
As CL stated in the comments, DDL is fully transactional in SQLite. So, for each database in our system, we wrap it in a transaction, and it executes atomically. We leverage the application to ensure that all databases upgrade successfully if any fail during upgrade.
I'm looking at switching from MySQL Workbench to Navicat because we're using MariaDB and the incompatibilities are starting to annoy me.
I'm working through the issues of getting Navicat to run on Centos under WINE but assume I will succeed (edit: this failed. The "linux" version requires WINE. Navicat will sort of run with a bit of hacking, but critical features rely on MS-Windows/WINE)
How do I get Navicat to work with git (or any other source code control)? Workbench is sufficiently primitive that file changes either get picked up automatically or completely ignored (almost always a dialog "file on disk has changed, reload?")
Specific problems:
when adding new query files Navicat only seems to rescan the folder when I add a new query. Is there a smart way to do that? (edit: no. You can manually refresh one file at a time by right clicking)
model and query files are buried deep in the WINE tree. Can I relocate them or or symlinks work? I'd rather keep all the DB-related code in one repo, rather than having a special Navicat repo. (edit: yes, but the explanation of how to do so is lengthy)
is there a way to merge a model file if more than one person has changed it? Workbench can't do this but I'd really like the feature. (edit: no, never. Merge the schema SQL files instead)
Also, bonus question: can we make multiple edits using Navicat other than repeated use of the GUI? If I want to change (say) a bunch of columns from VARCHAR(255) to CHAR(20) I'd normally script that in SQL but Navicat models don't do reverse engineering, only "delete the table from the model then re-import it" so there doesn't seem to be a non-tedious way to do that. (edit: no, but they might look at it in the future)
Final edit: I used the Navicat forums and the team were very helpful, but fundamentally Navicat is Windows software and the 64-bit purists behind Centos will never support WINE. For most Linux users this is not a problem, but I work with Centos enthusiasts and have long since lost the argument about which distro to use.
To the 1st question, you can sync it in different ways with a remote database/folder, when you are managing the database with Navicat, just right-click in your current connection and press "refresh", so you will be updated with the server changes. You also can do it with a programmed task.
Another matter is, why would you want to run navicat from wine when it has a native linux version? (I hope that answers the 2nd question)
For the 3rd question note that Navicat has an internal utility to sync data between servers, so you don't need git at all, or at most, you can automate the structure exportation and then sync it with a git repository (in form of a .sql file)
IMHO you need to review your concepts about mariadb and navicat, both are quite flexible and offer several ways to do such things you propose, like sync the data and they also allow to insert git in the workflow, just review your strategy and try to apply some new perspective with the available features.
I am creating web service in zend framework which uses DynamoDB. So I installed DynamoDB in local. But it's not easy to use. Even for inserting data and update any data for testing for purpose I have to write a script.
Is there any DynamoDB client available for MAC ? In which we can insert/update/delete data from UI.
EDIT
Doubts
1) Do I have to run a SQL to see table data? I thought there would be GUI for this.
2) I am not able to use where clause in SQL. What if I want to see one or two records from all? Is there a way to use conditions in this?
3) All fields of a row is not visible and I am not able to scroll it horizontally ?
YES! I've finally found a solution after struggling with this myself:
Run your local dynamodb jar with the following command java -jar DynamoDBLocal.jar -dbPath . [this will create a file in whatever directory the Dynamo jar is located in].
Download SQLite Database Browser and extract/install it.
Start SQLite Database Browser
Navigate to "Open Database" from the file menu
Navigate to the directory from 1. Select the file [in this case, ****_us-east-1]
You should then see the database contents!!
Hope this helps - it's been frustrating me no end!
!! EDIT !! - in response to original question edit.

Yes - you can do a simple "select" statement, for instance in my examples: "SELECT * FROM tweet_item" returns me the following screenshot:
Seemingly inadvertanyl - whilst I couldn't get the direct SELECT * FROM XX WHERE XX to work, the like statement does. For instance SELECT * FROM tweet_item where tweet_item.hashKey like "%425665354447462400%" returns me the tweet with tweet_id [my hashKey] of 425665354447462400:
Strange - I seem to be able to scroll quite happily [although it is Windows not Mac]. It also automatically tries to re-size the outer frame, too.
I ran into this problem and found a relatively new solution : https://github.com/aaronshaf/dynamodb-admin
It has provision for GET/POST/PUT/DELETE.
Although its a paid product, which is a bummer, RazorSQL now supports DynamoDB as well, and does let you change the AWS endpoint to point to a local installation.
The mac version (with a free trial) is available here:
http://razorsql.com/download_mac.html
Here is a very useful ui tool https://github.com/YoyaTeam/dynamodb-manager，It supports almost all data operations。
For Eclipse users:
Amazon provides AWS Toolkit for Eclipse IDE. It can view local and cloud databases. Also if you are using different regions, it has ability to choose from different regions.
You can create attributes, add keys etc..
For installation follow this link: http://docs.aws.amazon.com/toolkit-for-eclipse/v1/user-guide/getting-started.html
Dynobase is new DynamoDB GUI Client which also lets you browse and manipulate local DynamoDB instances: https://dynobase.dev/dynamodb-local-admin-gui/
Unfortunately, it's paid but there's free 7-days trial, works on Mac, Windows and Linux: https://dynobase.dev/
I am interested in testing flyway and if I am not wrong I read that it supports db changes both through java and SQL. I am a dba and familiar with SQL but not java.
I read through the “Getting Started” page and wanted to try out the sample application available under the “Downloads tab” link however I couldn’t find any readme document explaining the available downloads which appeared to contain .jar files.
Q) is there an instruction manual for a newbies to explain how to put together this sample application?
Q) can one uses flyway without knowing java? If yes, please provide any how-to url/notes/documents available. If not do you have any how-to for one to get started with java just enough to operate this tool?
Thanks Bob
I think you might find the command line tool useful:
http://flywaydb.org/documentation/commandline/
As it says on the website:
The Flyway command-line tool is meant for users who
do not run their applications on the JVM
wish to migration their database from the command-line without having to install Maven
You may need to browse the source code to figure out some more details:
https://github.com/flyway/flyway
Although I think you should be able to adapt the regular documentation to the CLI option.
Try starting here:
