Thread Rules
1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks. |
Man, Ruby is indeed a magic language...
My CI pipeline started failing out of the blue so I went on to investigate. All the tests are green in development and for some reason in test environment they always fail (but only the first time they run, if you run them again they're all green).
The reason they're failing seems to be the fact that the test thinks that one of the models from the fixtures is invalid (when it is). I've tried changing the test to create brand new valid model instead of loading it from the fixtures (thought it might be a timing thing) but it's still failing (and only on the first run).
Such magic. Not wow.

Your selectedElement was a string. Not an object...
Starting from his example -- you can fix that by changing the select from
<select ng-model="selectedPeriod">
<option ng-repeat="option in testData.Table1" value="{{option}}">{{option.Index}}</option>
</select>
to
<select ng-model="selectedPeriod" ng-options="option.Index for option in testData.Table1">
</select>
I'd have to dig deeper to figure out a different solution with you still creating the options but I think that this --> value="{{option}}" on the original is turning the object into a string and setting that as the value. So even though your debug output looks like it's selecting the object correctly it wasn't. Switching it to the second syntax fixed it for me.

It seems that model validations were dependent on stuff being (or not) in the DB. Since fixtures are loaded asynchronously model showed up as invalid. Super dumb.

Thanks guys. I finally ended up fixing it by setting ng-value = 'option', instead of value = "{{option}}", since the latter syntax stringifies it.
I almost immediately figured it out once I created a plunk and posted it here, so in some ways taking it out of a large project and putting it into a plunk helped me understand my mistakes.
Also ng-options seems like an elegant solution. Have been a windows developer for almost 9 years now, so angularjs (and web development) is still pretty new to me.
Edit: Also to you guys, how do you manage Datamodels in angularjs. Coming from a world of strongly typed objects and well defined models, web development seems like a strange beast to get used to, especially for a large enterprise application that involves large amounts of financial and accounting data.

Does anyone else find networking events really awkward? I have no problem talking to people normally, but whenever I want something from them it becomes much more difficult.

Could someone help me identify a possible issue with Docker? For some bizarre reason our GitLab CI pipeline started failing since October 1st and I have no idea why it would be so (I'm pretty newb with Docker).

It never did all this db setup stuff before and everything was working fine just a day before. Any idea what could be the reason for those failures? Perhaps the machine run out of memory and killed some processes, now Docker has info about images that have been killed or something?
|
Did those warnings about network disconnects happen before and possible zombie containers?
|
Hard to tell. What does 'docker inspect network' say? You could try to 'docker network disconnect --force' the runner-ac3d6fad-project-17-concurrent-0-redis or runner-ac3d6fad-project-17-concurrent-0-redis-wait-for-service.

Turns out that for some reason we had a zombie runner which didn't shut down properly after finishing/failing a job in the pipeline. This prevented new runners to execute.

I wanted to git gud at OOP. Now I have strategies built upon more abstract strategies which select factories built upon more abstract factories and it's all encompassed in even more abstractions with managers, providers, resolvers, handlers, services and such. All this to parse single JSON file...

We are learning about, and implementing in our latest project, DFAs and NFAs. I think they are pretty interesting and I was surprised I had literally never heard of them.
The professor never really told us what their applications are, though. It seems to me that their role is basically to pattern match? They are probably used to implement regex, for example?
Have any of you used these in the real world?

Someone who is good with OOP would use an existing parser.

I am using an existing parser. But I need to parse the contents of the JSON and then map them to our database structure creating/updating records as necessary.

Every time I see stuff like this I always just want to post the image from the medium article showing java having the highest paid salaries. >_<
Which parsing library are you using? You parsing into json objects and then doing the data transformations yourself or using something like Gson and going straight to objects? You even in java?
Edit: I think you're in ruby, right?
Design patterns never made much sense to me until I started testing. Once you starting writing code for testability they make a ton of sense. If you are just trying to break things down because you "want to git gud" (yeah I know you're joking), then it's really hard to see where you really need to make your seams.

Yes, they are used in regex, and are heavily used in constructing and parsing programming languages in unambiguous ways.
You will probably never need to use them in the real world. I only ever used them for practical purposes in my compilers class. They are definitely interesting though!

Yeah. Also, my original post was kind of a sitire (pointed at myself of course) about how you can sometimes go overboard and do simple stuff in most convoluted ways.
