Hello! I''ve modified ActiveRecord a bit to support enum columns. This is tested only with MySQL, and maybe needs some changes for other adapters (if they use another syntax or quoting style). I believe this patch should be tested well, so I haven''t (yet) tried to post it to the official Trac. It is also not solid-as-a-rock when it comes to quoting ENUM values. After

I have a mysql database that I am trying to use migrations on. The problem that I am having is that when I create a blob field in my migration file like so: t.column "data", :binary, :limit => 15.megabytes, :null => false rails changes it to this in the schema: t.column "data", :binary, :default => "", :null => false not only is this not what I wanted

Hello, everyone, I encounter a strange problem about llvm type i64 and C++ type int64_t. I instrumented a program to call the function 'myFunction' in the C++ shared library. 'myFunction' is something like this: int64_t myFunction() { int64_t retValue; ... std::cout << "retValue: " << retValue << "\n"; return retValue; }

Hi Tim Northover, I just use Mac OS X, Intel Core i5. 'retValue' is initialized, computed, and then returned from 'myFunction', so I think this problem is not introduced by uninitialized value. In addition, '306205760' is not a meaningless value, but the result of truncating '140583176769504' to 32 bits. Actually, I instrumented some call instructions for value

I have not been able to get DB migrations to work at all in Rails 1.0 for me. On multiple platforms I continually get the same errors. It took me awhile to figure out some initial things, such as Migrations don''t seem to support Enum column types, and doesn''t really support Foreign key relationships (the constraints at least). After changing my DB schema to jive more with the

Hi, I am developing a peer-to-peer video conference application which uses speex as a codec for the voice. I am new to speex, so please bear with me if I asked the obvious. After I added the encode and decode function to my MFC app, I heard a constant background noise, even when no one is speaking into the microphone. #define FRAME_SIZE 160 The application is coded in MFC C++. The record

Hi John, Thanks for your reply. Yes, my output device is in 8-bit mode, same as my input mode. I'm actually working in char (8 bit) arrays. Is it necessary to work in signed short integers only? I changed all the short arrays in the example to char. Carine ----- Original Message ---- From: John Miles <jmiles@pop.net> To: carineliang@yahoo.com.sg; speex-dev@xiph.org Sent: Thursday,

Hi, I've changed the m_waveFormatEx.wBitsPerSample for both record buffer and playSound buffer, changed my array from char to short and I'm still getting the same constant background noise. I notice that when I talk into the mike, I will get a slightly louder noise, can't hear any clear speech... Any idea what's wrong? Regards, Carine ----- Original Message ---- From: John Miles

Hi, I'm still unable to get rid of the background noise though I've changed the PCM samples to 16 bit. I'm began to wonder if I can just take the PCM samples and encode them. What my application tries to do is to record the voice from a microphone, encode it, send it via the socket to a peer, decode at the peer's side and play the voice. My application works fine without the

All, Rails 1.1.6. Any AR find() call that generates a SELECT * type query against a table with a DATETIME column in SQL Server whose value occurs before 1970 will fail, because of the coercion of SQL Server datetime types to Time values in Ruby. See sqlserver_adapter.rb line 490 (record[col] = record[col].to_time if record[col].is_a? DBI::Timestamp) If I remove the coercion (just commenting

Hi, A few days ago I submitted the following ticket http://dev.rubyonrails.com/ticket/596 asking that ActiveRecord::Timestamp also apply for the join tables of habtm. The answer was that it was left for milestone 1.x, and since I think that without this functionality rails 1.0 would be incomplete, I''m raising the issue here to discuss it. My use case is very simple, I

Hello, I''m a beginner, so any hints are appreciated; I''m still trying to find my way around Rails code. For a bug I''ve found I need to create a table called "values" so I added this: create_table :values do |t| t.integer :value end among the other table creations in activerecord/test/cases/migration_test.rb. Is that ok? But then, when I run the tests
