title: svn:ignore 'file' is not under version control
body: <p>I know that there are a quite a few questions on this out there however none of them make sense so I was hoping that someone could dumb it down for me, cause I am just not getting it. </p>
  
  <p>I have a project (rails) and I want to ignore the SQLite files (among others) from the repository. I have tried adding the files and then ignoring with</p>
  
  <pre><code>$ svn propedit svn:ignore "development.sqlite3" db    
  svn: 'development.sqlite3' is not under version control
  
  $ svn propedit svn:ignore "*.sqlite3" db    
  svn: '*.sqlite3' is not under version control
  </code></pre>
  
  <p>I have tried removing the files and trying the same, and many other combinations and I simply cannot get it to work. I dumped the current build and pulled it down again just to make sure that I was working with a clean copy of the project and no change. </p>
  
  <p>I know that I am missing something, probably something simple, so if someone out there could give me a hand I would appreciate it.</p>
  
  <p>thanks patrick</p>
