• postgres syntax question for OR?

  - by Dashiell0415

  The first one below works, but, just wanted to see if there's a better way... If I'm trying to find all records that start with 'C' with either a flag of 2 or a status of 9, do I need to incorporate the 'C' criteria twice? i.e., "SELECT * FROM mytable WHERE name like 'C%' AND flag = 2 OR name like 'C%' AND status = 9" Or, is there a way quicker way to write it so that I only need to set 'C%' once?

• Is there a way to have three way habtm associations in rails / activerecord?

  - by txwikinger

  Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?

  Suppose I want to write my own preprocessor.

Thanks!

• Graph generation on iPhone

  - by Parrots

  Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?

• Create ActiveRecord migration then edit in one step?

  - by geosteve

  I find myself doing this a lot: script/generate migration my_new_migration .. then select & copy the generated filename, then paste it into vi to actually write the migration. Is there any way to do this in one step? i.e. when the script/generate migration runs, it creates the file the automatically opens that file in an editor? (I'm working in an SSH terminal window on linux..)

  - by Attilah

  Is it possible to write a mobile application with J2ME and whenever we want to implement a functionality not offered by J2ME call native mobile API ? (kind of like what is done with .NET, whenever you need something not provided, you just call the Win32 API from the .NET platform).

• What does <![CDATA[]]> in XML mean?

  - by mystify

  I often find this strange CDATA tag in XML files: <![CDATA[]]> I have observed that this CDATA tag always comes at the beginning, and then followed by some stuff. But sometimes it is used, sometimes it is not. I assume it is to mark that some "data" will be inserted after that. But what kind of "data"? Isn't anything I write in XML tags some sort of "data"?

• When is better to use a parser such as ANTLR vs. writing your own parsing code?

  - by ViralShah

  I need to parse a simple DSL which looks like this: funcA Type1 a (funcB Type1 b) ReturnType c As I have no experience with grammer parsing tools, I thought it would be quicker to write a basic parser myself (in Java). Would it be better, even for a simple DSL, for me to use something like ANTLR and construct a proper grammer definition?
