similar to: Database connection parameters are tied to the filesystem

I know this isn''t Python, but I''d like to get a view on the ''one obvious'' way to set up an SQLite (or other) database and its location per-app. I''ve got a bit lost with the Camping 2 changes and various code snippets I have kicking around. 1. is it best to set up the DB creation/connection: 1.1 at the end of the app

Hi all, I have a legacy table which I cannot get to work with ActiveRecord (no ids etc). All I want is to create a class which opens a connection manually and allows me to execute some plain SQL statements. What I can''t figure out is how to either build up a connection and execute queries from a non-AR inherited class, or how to create a AR-inherited class minus all the AR magic and

Hi, I read the example in http://wiki.rubyonrails.com/rails/pages/HowtoUseMultipleDatabases, it show us how to connect to other database, each time we start a new action, however, this doesn''t work while you try to connect to two different database within the same action. SO I wonder is it possible to bind to two or more database within the same action???? Thanks you very much Saiho

Hi all - I have a need to have my models write to one database and read from another. From what I''ve read, Rails doesn''t do this out of the box. I came up with something that does work, but I''m wondering if there is something I''m missing in the code below that''s going to bite me, such as establish_connection creating a huge number of objects as

Hi Everyone, I am trying to connect to multiple databases and followed along the Recipe in Chad Fowlers ''Rails Recipes'' book (which basically is about establishing the connection in a subclass of ActiveRecord::Base, and inheriting all classes in need of this connection from this class) Chad Fowler says: "You won''t be able to instantiate an External, of course,

Hello! I'm collecting data on a refrigerator that I'm using to cure meat. Specifically I am collection humidity and temperature readings. The temperature readings look sinusoidal (due to the refrigerator turning on and off). I'd like to calculate the frequency and period of the wave so that I can determine if modifications I make to the equipment are increasing or decreasing

Hi all. No matter what I do I can''t get rails to see my MySQL database. All details are below. I really appreciate any assistance. Thanks!!! DETAILS ------- 1. I''m using Rails 1.1.4 with Ruby 1.8.4 on Mac OS X 10.4.7. I have installed the MySQL bindings following the instructions here:

Hi All, I am new to this list and to rails. So far I am loving the way in which it is easy to put together web pages with a database backend. I would love to use the rails functionality (to do the sql queries) and then process the results using some very cpu intensuve tasks. The results will take far longer than it is viable to use a web browser to view the results. I would like to see the

This seems like such an obvious idea that I''m having trouble believing I''m the first to think of it. Why not take ranges containing Float::INFINITY and translate them to the appropriate greater than or less than comparisons? Example: class Person scope :voters, -> { where(born_on: (-Float::INFINITY..18.years.ago)) } end This would generate something along the lines of

All, I am working through the ''depot'' sample application from the "Pragmatic Programmers" book on my powerbook. I was going through the install process on http://hivelogic.com/articles/2005/12/01/ ruby_rails_lighttpd_mysql_tiger and it seemed to work fine. But when I try to create the first table, I get the following error, and I have no idea what this means. Any

Hi All, I know we're late in the release process, but I've discovered a regression I believe is serious enough to hold the release [1]. The regression is in usages of `__builtin_constant_p` applied to a dereferenced pointer in a constant expression. In certain cases Clang now rejects this as a non-constant expression [2]. This regression will have a larger impact than it initially

I am getting an error that I can''t figure out. I have a class called Test with 3 fields, id, x, and y. When I do Test.new(''x''=>1, ''y''=>2).save, I get an error saying that id (my ''not null primary key'') can''t be null. But isn''t active record supposed to deal with setting that for me? Here''s the code

I have a module as shown below and when I extend an active record to use it, I can not access the primary_key method. In a simple test program using a similar approach where active record is not involved, access to the class methods seems to work ok. What can I do to make this work or so that I can access the class methods ? ################################## require

Hi all, I''ve got some tables with fixed amounts of data in them (a "states" table, for example). For tables like this I can easily put *all* of the data in the fixture. For general futzing purposes, and for those times I want to reload a database from scratch outside of testing (for whatever reason), what''s the best approach? I thought perhaps ActiveRecord::Base had

Hi Bill, I committed a fix already as r355743 [1], and it fixes `test2` as well. I believe we should merge this into 8.0. /Eric [1] https://github.com/llvm/llvm-project/commit/680e865c313a80b6ec329abde61e1f0c66bdc103 On Fri, Mar 8, 2019 at 5:46 PM Bill Wendling <isanbard at gmail.com> wrote: > Hi Eric, > > The attached patch may help matters, though it now fails because

Pinging @tenderlove Some questions on how best to move forward with this: 1.) AC::Live is making use of the stream object on ActionDispatch::Response. Should the rack.hijack_io object be used instead of this in AC::Live or should ActionDispatch::Response be changed to use rack.hijack_io? 2.) What do you think about changing AC::Live to work with adapters? I suspect the primary use case for

I really like how Active Record logs the SQL that is executed inside of rails. Is there a way to get the SQL output when using Active Record outside of rails?

Dear all, Please help me in this regards, I am using models to access LegacySchemas using set_table_name and set_primary_key... [code for model] class CdDetails < ActiveRecord::Base def self.find_data set_table_name ''cd_details'' set_primary_key ''cd_label'' find (:first, :select => "cd_label") end
