How to remove

Just run: gem uninstall huqua and press enter

why it fun?

If you are a newbie in ruby on rails development, so many times, you can test your database on the local environment to make sure your connection to the database is successful or success to import data (from SQL or CSV...)

You have 2 choices.

1: You can open an administrator platform for PostgreSQL like pgadmin

• need to install a tool (not good for a weak computer).
• open the tool and checking (wasting time and not good for a weak computer again :D)

2: You can access the database from the terminal.

• step 1: type command rails c
• step 2: try to remember the model name and typing like Cat.first to see the first record.
• step 3: need to exit to back terminal.
• do again when you need to check something or open a new terminal window. ...

So I think I can make it simple, when I need to check structure simple, like check new record can save in DB or check number records of a table.

So I build a simple tool. At this time, it work only with PostgreSQL. 😐
