I'm getting the following 'incompatible library version' error when I try and access my Ruby on Rails website in development mode. incompatible library version - /var/www/vhosts/launch.site.com/httpdocs/vendor/bundle/ruby/2.2.0/gems/pg-0.18.4/lib/pg_ext.so (LoadError) /var/www/vhosts/launch.site.com/httpdocs/vendor/bundle/ruby/2.2.0/gems/pg-0.18.4/lib/pg.rb:4:in `require' /var/www/vhosts/launch.site.com/httpdocs/vendor/bundle/ruby/2.2.0/gems/pg-0.18.4/lib/pg.rb:4:in `<top (required)>' /usr/local/rvm/gems/ruby-2.2.3/gems/bundler-1.10.6/lib/bundler/runtime.rb:76:in `require' /usr/local/rvm/gems

How can I modify a where/like condition on a search query in Rails: find(:all, :conditions => ["lower(name) LIKE ?", "%#{search.downcase}%"]) so that the results are matched irrespective of accents? (eg métro = metro). Because I'm using utf8, I can't use "to_ascii". Production is running on Heroku. Erwin Brandstetter Poor man's solution If you are able to create a function, you can use this one. I compiled the list starting here and added to it over time. It is pretty complete. You may even want to remove some characters: CREATE OR REPLACE FUNCTION lower_unaccent(text) RETURNS text AS $func$

first things first, please excuse my utter noobness. I really tried to find a solution out there, but now i'm stuck and completely clueless. i'm trying to deploy a rails 3 app on a distant server ; when developping on my local VM, no problem showed. But now, when i try to run rake db:create it fails, with error (here translated, since i'm french): FATAL : password authentication failed for user <<mylogin>> here's my database.yml : login: &login adapter: postgresql username: mylogin password: mypassword host: localhost port: 5432 encoding: UTF8 development: <<: *login database: somesite

I'm having an issue selecting dates properly from Postgres - they are being stored in UTC, but not converting with the Date() function properly. Converting the timestamp to a date gives me the wrong date if it's past 4pm PST. 2012-06-21 should be 2012-06-20 in this case. The starts_at column datatype is timestamp without time zone . Here are my queries: Without converting to PST timezone: Select starts_at from schedules where id = 40; starts_at --------------------- 2012-06-21 01:00:00 Converting gives this: Select (starts_at at time zone 'pst') from schedules where id = 40; timezone ---------

I recently got a new machine and would now like to work on my projects from Github. I'm curious as to how to properly set up the Postgres database on my local machine. I have postgresql , pgadmin3 and libpq-dev installed on Ubuntu (12.04). I pull down the project: git clone https://github.com/thebenedict/cowsnhills.git and run: bundle . When I run: rake db:create && rake db:schema:load I get this error: rake db:create && rake db:schema:load FATAL: password authentication failed for user "cnh" FATAL: password authentication failed for user "cnh" .... The config/database.yml file looks like this

I'm using XAMPP as my installation folder for PostgreSQL 9.3. C:\xampp\pgsql\9.3 And now I'm trying to install PostgreSQL gem using that directory as a reference: gem install pg -- --with-pg-include="C:\xampp\pgsql\9.3\include" --with-pg-lib="C:\xampp\pgsql\9.3\lib" --with-pg-config="C:\xampp\pgsql\9.3\bin\pg_config" But this command failed with errors listed below: ERROR: Error installing pg: ERROR: Failed to build gem native extension. C:/Ruby/Ruby200/bin/ruby.exe extconf.rb --with-pg-include=C:\xampp\pgsql\9.3 \include --with-pg-lib=C:\xampp\pgsql\9.3\lib --with-pg-config=C:\xampp\pgsql\9.

Say I have a model called Transaction which has a :transaction_code attribute. I want that attribute to be automatically filled with a sequence number which may differ from id (e.g. Transaction with id=1 could have transaction_code=1000 ). I have tried to create a sequence on postgres and then making the default value for the transaction_code column the nextval of that sequence. The thing is, if I do not assign any value to @transaction.transaction_code on RoR, when I issue a @transaction.save on RoR, it tries to do the following SQL: INSERT INTO transactions (transaction_code) VALUES (NULL);
