tutorial issues

[mattford63]

Hi, great tutorial! I very much liked the style of it.

A couple of comments:

• the component use doesn't seem idiomatic particularly the main page of component says not to add dependencies within components themselves (rather do so at system-map creation time)
• the latter stages of the tutorial had some bugs (or code changes not in the text). I needed to update

• the cgg-shema,
• the db creation (primary key and foreign key on ratings table)
• I couldn't get the $1 form of queries working vs ?.
• Upserts need to be an execution.

A working version (for me at least) is here Please see this

each commit roughly following on with the tutorial stages.

Thanks for the help, I'll be looking into these issues. All good points.

Sorry for the long delay.

I'll consider some changes w.r.t. components and dependencies; At Walmart, we developed and use https://github.com/walmartlabs/schematic to manage component configuration and dependencies, but I don't want to introduce that into the tutorial.

I think (can't quite be sure) that I did find an official code repo of the tutorial that has some of these things fixed. That would be a better source of truth. Those changes hadn't made it into the doc code examples though.

The process of getting code form the tutorial example app into the lacinia documentation is ... tortuous.

I've completely rewritten the tutorial as well as other documentation.
