[Rails] [JOBS] Looking for full-stack dev Partner

[Matthew Cordasco]

We are a small but dedicated startup that is creating the next generation 
crowdsourcing platform.  We have spent the past two years building and 
launching our product and are now gaining paying customers at a good clip.

It's time for us to expand the core development team by adding another 
Partner.

Want to be employee #3?

We are looking for a very special teammate:
- join our core product team
- expand our core crowdsourcing platform 
- breath life into new and awesome features
- drive innovation
- help to build a fantastic company

You love working in startups.  You love wearing multiple hats and are 
extremely curious.  You are a staunch technologist.  We prefer a degree in 
CS or equiv (formal training is good but it's not required), have 3+ years 
with RoR and associated back-end and front-end technologies (Angular, 
Bootstrap, etc.)  


** This is an equity only role. **


Full time or part time?  We are open to either.  Realistically, we don't 
expect anyone to jump in full-time at the beginning.  Start small and grow 
with success.
Will this turn into a full-time gig?  You bet.  Long term we would love 
100% of your commitment.  But we don't need to rush into it.
Will this ever be a paying gig?  You bet.  But since this is a partner 
role, its equity to start.  We can add a cash component down the road.  The 
beauty of equity is that aligns all of our interests perfectly.  


Who are we?
On-demand crowdtesting for websites and mobile apps.  Our platform has 
30,000 testers around the world.
https://mycrowd.com
We are startup veterans, who have founded and sold several companies before 
this.  We know the difference between hiring a contractor and bringing on a 
new partnerwe are looking for our next partner.

We look forward to hearing from you.  Ping us and say hi!

[Rails] Active Record has_one through

[Chris Berry]

I have two tables in my app which I am attempting to relate through a
join table.  The Artist class which uses 'has_many through', works as
expected.  However, the Event class using 'has_one through', brings back
nil.

class Artist < ActiveRecord::Base
  has_many :artist_events, dependent: :destroy
  has_many :events, through: :artist_events
end

class Event < ActiveRecord::Base
  belongs_to :artist_event
  has_one :artist, through: :artist_events
end

class ArtistEvent < ActiveRecord::Base
  belongs_to :artist
  belongs_to :event
end

In irb i get all events for an artist with "a.events" (where a =
Artist.first).  But e.artist returns 'nil'. Whats strange is that
a.artist_event returns nill as well. However, when I run a 'find_by' on
the artist_event table and use e.id, the artist_event is returned.

I have tried changing the Event class to use has_one as opposed to
belongs_to, without effect.

What am I missing?  Do I need to have an index in the schema?

The question is meaningless, unless I misunderstand what you are
asking, erb is a server side technology and js is client side.  Most
non-trivial sites require both.

No. Again: *what is your use case*?

Stability/uptime guarantees, multi-region availability, access latency,
security (PCI? HIPAA?) - there are any number of things that might
be relevant to *your specific project*.

You decide what's important and then research cloud providers to
see who meets *your* requirements.

[Rails] Ruby on Rails way of managing views

[Taras Matsyk]

Hi RoR experts,

I have a really small question which is probably depends on a personal
taste but I want to know your opinion.
I was told that RoR is widely used to render erb files and allows to
deliver things faster however I do know about the dark side of using the
rails api and some js framework like ember. You might remember my asking
the question about your preferred js framework, however js is a matter
of taste.

So, one more time. The main question : is it still the case that erb
could give some advantage in app support or delivery time over the rails
api with some js framework? What is your opinion on this?

OK, still missing the point:

What do you mean by "good"? What *exactly* do you care about?

What do you mean by "cheapest"? Lowest bandwidth charges?
Lowest storage charges? Some ratio of the two?

And how would anyone else answer that without knowing the details
of your specific use case?

Please quote the relevant parts of the previous message when replying.
Since you have not done so it is not easy to see which points you are
commenting on.

I don't know what you mean by "parsed around objects"  I guess you
probably meant "passed around objects" but even then I don't know what
you mean, and I also don't know what you mean by "monitor it".
Also you ask what if the cart has problems obtaining the price
properly, again I don't know what you mean.

Please try again to ask the questions.

You might want to consider the Postgres JSON support - it will allow for 
queries deep into the data.

BUT you should first think hard about whether this should be a serialized 
field at all; one of the primary tradeoffs you make with serialized fields 
vs. storing the data broken out into related records is *searchability*. If 
you're going to be querying the values extensively, maybe an alternative 
approach within your DB is better - or perhaps even a secondary indexing 
system (Solr / ElasticSearch / etc).

I suggest working right through railstutorial.org, which is free to
use online.  I am not saying there are not others just as good but it
is the one I used and it got me going very quickly.

That is interesting.  It appears that because no-one could come up
with a good example of how using the model can go wrong the whole
section was removed, meaning that the guide has no example of how to
use a model in a migration.  Not entirely sure I would agree with that
logic.

Two sites that are pretty helpful that have screencasts are railscasts.com 
(older content but still good) and gorails.com.  Check them out and get a feel 
for the framework.  I think you’ll love it!

[Rails] Ruby on Rails

[Prashant Girennavar]

Hello Experts,

 I am new to RoR and have knowledge of programming(asp.net,c#). I wanted to 
start of with Ruby as its framework like Rails,Dashing Etc excites me. I 
did try going through some ebooks , but its kind of hard to understand the 
sytax and follow the flow of ruby on rails.

 Can someone tell me, how to approach the learning of RoR? 

Thanks,

-Prashant Girennavar.

Андрей Молчанов is correct when he says that you should not store the
same information in two places in the database.  However there are
certainly cases where it is necessary to adjust data in existing
tables during a migration.  Have a look at [1] which has examples of
how to do this and notes some pitfalls to watch out for.

It seems that section has been removed from the latest guides, I don't
know why.  Anyone know whether it was removed for a good reason?
