I’m trying to bring Adopt a Hydrant to Helsinki.
So far I've managed to change the location of the map to Helsinki, build a database with postgreSQL, set the private key and deploy the app in heroku (the app is available at paloposti.herokuapp.com).
However no hydrants are showing in the map. I’ve replaced all the latitudes and longitutes in the seeds.rb file and run:
bundle exec rake db:create
bundle exec rake db:schema:load
rake db:setup
bundle exec rake db:seed
I’m sure I’m missing something very stupid, but what?
my logs :

When you run bundle exec rake db:seed. You are actually just running it on your local machine. So to seed to the database on heroku you would run heroku run rake db:seed.

Working with these models:

Quote.rb

belongs_to :user

Country_Quote.rb

Via console, I can run this query and I get the result I'm looking for:
theresults = Quote.joins(:countries).where("countries.name = 'España'")
theresults.where(shippingtype: 'Urgente').first.cost
However when I try to run a similar query within build_controller.rb (it's a controller to handle my Wicked gem for the model Order) I get this error:

You are using the variable in double quotes which is interpreted as string.
temporderregularshippingprice = #user.quotes.joins(:countries).where("countries.name = #order.country" )
Use this instead
temporderregularshippingprice = #user.quotes.joins(:countries).where("countries.name = ?", #order.country )
OR
temporderregularshippingprice = #user.quotes.joins(:countries).where(countries: { name: #order.country })
I really have a big trouble.
I setup socket.io with Node.js on Heroku(1X dyno * 2), and a iOS app use socket.io-client-swift to connect to Node.js server.
There are about 10-20 users connecting server.
In first 10 minutes connection, everything is ok. Afterwards, the connections start disconnecting and then connect. And they repeat (disconnect, connect, disconnect, connect, ...).

The app.js file
var io = require('socket.io')(process.env.PORT || 3001);
io.use(function (socket, next){
var token = socket.request._query.token;
authorize(token, function(user) {
.... // some authorization work
next();
}, function(error){
next(new Error('API Token wrong'));
});

io.on('connection', function (socket) {

});
I'm using Rails 4's template-caching features extensively. Lots of nested templates and touch: true on lots of models. Overall it has proven to be a comprehensive solution that is easy to reason about.
I recently implemented a feature where multiple background jobs are created which iterate through hundreds of objects and create other objects in relation to them. When each of these objects is created, the same user is touched.
So, these two jobs run in parallel:
job A: serially creates hundreds of objects, each time touching User 123
job B: serially creates hundreds of objects, each time touching User 123
Upon deploying this feature, I discovered that sometimes postgres detects a deadlock and cancels two queries which are waiting for one another. The query shown in the error is always the touch query (update User 123's updated_at with the current time).

I am surprised that this deadlock occurs, because neither the row nor the table are being locked. Shouldn't the second transaction simply wait for the first to finish?
update: minimal sql-only reproduction of bug here: https://gist.github.com/jjb/9823023
Your original log was incomplete, because the first UPDATEs didn't have a transaction ID, so they weren't included in the original log.
Now that the log with virtual txids is there, you can see that PostgreSQL is behaving exactly as designed.
The relevant lines are:
pid: 33627 tid: 0 vtid: 3/28 LOG: statement: UPDATE "users" SET "updated_at" = '2014-03-27 23:58:02.619282' WHERE "users"."id" = 2

Here:
3/28 locks id=2 for update
4/25 locks id=1 for update
3/28 attempts to lock id=1 for update, blocking on the lock held by 4/25
4/25 attempts to lock id=2 for update, blocking on the lock held by 3/28
At this point neither transaction can make progress, so PostgreSQL aborts one of them.
To prevent this from happening, your application must ensure that it always acquires locks in the same order. Where that is not possible, it must try to only work with one dependent object in any given transaction, so ordering issues cannot arise. Or it must be prepared to handle deadlocks by trapping the exception and re-issuing the transaction.
To learn more, see Explicit locking in the manual.
I have a Rails 3.0 app (working on a 3.2 upgrade) and whenever someone requests a template that doesn't exist it gives a 500 error in production. For instance mysite.com/blog_posts/532 sends the post with ID 532 back as HTML no problem, but if for some reason mysite.com/blog_posts/532.txt is requested, the app raises a 500 ActionView::MissingTemplate error.
This shouldn't happen, because the template shouldn't be there in the first place. It should more properly be a 404 error, or perhaps just show the HTML template.
How can I make the app either show a 404 error for all missing-template errors, or show the default HTML template instead of giving a 500?

I am trying to install gitorious on my personal server but I am not very familiar with Ruby or the frameworks and scripts involved in getting to the finish line.
I am following the following instructions to install gitorious on my CentOS 5.4 server:
http://www.tikalk.com/alm/blog/installing-gitorious-centos-55
The site comes up but as soon as I click on the login link I get the 500 error screen and an exception report is emailed to me. The error is reported as an "invalid byte sequence" and google tells me that it's related to Ruby 1.9. From what I've read, gitorious.org is using 1.9 and others got it working, so now I'm curious as to why it's not working on my system.
Judging from the backtrace, it looks like the invalid encoding might be coming from the database which is a MySQL 5.0.77 in my case. All tables in the gitorious database have their DEFAULT_CHARSET set to utf8.
You can make out the version of most components that I have installed from the stack. I have rails 3.0.0 installed. If anything else would be useful, please comment and I'll reply.
The exception report goes like this:
A ArgumentError occurred in sessions#new:
invalid byte sequence in US-ASCII

In this post by Marius Mårnes Mathiesen, he recommends removing the i18n gem. Maybe that solves your problem.
