Try putting an &#39;!&#39; mark in front of the pattern you don&#39;t want to match - putting

    !*.cgi, !*.pm, !*.sql

in the File name patterns section is doing the job in a test I&#39;m doing with Eclipse 3.4.1 (when the pattern was just * there was a file of each type, with that pattern, it is only returning js and pl files).

I was afraid that it would be a bit naive with the patterns and just allow anything that matched one of them to succeed (ie an sql file would match !*.cgi), but this doesn&#39;t seem to be the case.

I have a models `A` and `B`, that are like this:

    class A(models.Model):
      title = models.CharField(max_length=20)
      (...)
    
    class B(models.Model):
      date = models.DateTimeField(auto_now_add=True)
      (...)
      a = models.ForeignKey(A)

Now I have some `A` and `B` objects, and I&#39;d like to get a query that selects all `A` objects that have less then 2 `B` pointing at them.

A is something like a pool thing, and users (the B) join pool. if there&#39;s only 1 or 0 joined, the pool shouldn&#39;t be displayed at all.

Is it possible with such model design? Or should I modify that a bit?

Django models - how to filter number of ForeignKey objects

Do they set `display: none` or `visibility: hidden`?

I&#39;m pretty sure `display: none` takes the element out of the normal flow, whilst `visibility: hidden` just hides the element but still has a reserved space for it.

Should I just go download the unpacked version and study it or does someone have a quick answer?

Is there a way to exclude say, image types in Aptana or Eclipse file search? I want to search all files that are not images rather than specifying all the file types that I want to search in.

Which Eclipse package should I choose for Python development with [PyDev][1]?

Nothing on the Eclipse homepage tells me what to choose, and the PyDev documentation assumes I already have Eclipse installed. Does it matter which Eclipse package I choose?

Instead of hardcoding the default @author template I would like Eclipse to use user&#39;s real name taken from account information (in Linux - but Windows solution is also welcome). Entering it somewhere into Eclipse configuration would be acceptable, too, alas I can&#39;t find the right place.

How to change the value of ${user} variable used in Eclipse templates

Are there any plugins/tools available to go through the classpath of an eclipse project (or workspace) and highlight any unused jars?

Finding unused jars used in an eclipse project

I use Eclipse with &quot;external&quot; projects - i.e. projects created from existing source.

Poking around in the workspace files, I cannot find any reference to these projects. My question is: how does Eclipse keep track of these projects?

I&#39;d like to be able to add such a project to the workspace automatically (by generating `.project` and `.classpath` files).

Where in an Eclipse workspace is the list of projects stored?

For some reason Eclipse is no longer showing me Java compilation Errors in the Problems View.

It is still showing Warnings.

This has suddenly happened and I cannot think of anything that I have changed which would affect this.

I am using the &quot;Maven Integration for Eclipse&quot; plugin but I have been for some time - not sure if this could have affected it or not.

Any ideas?

Eclipse Problems View not showing Errors anymore

I am starting to learn the [Clojure][1] programming language. Are there any recommendations for Clojure editors/IDEs on Mac OS X?

**Update 2009-09-23**: The Clojure space has changed tremendously since I originally posted this question. Many of the links below, especially those that refer to clojure-mode with Emacs, are out-of-date. The best Clojure IDE I found was the [Enclojure][2] Netbeans plugin which was recently released (2009-08-25).

**Update 2010-04-30**: Another very good article on this subject is *[Clojure IDEs - The Grand Tour][3]* by Lau B. Jensen. Also, for my own clojure development, I have actually moved to Emacs / [swank-clojure][4].

Clojure editor/IDE recommendations on Mac OS X

My Visual Studio (2008) Editor has stopped to underline Errors (this nifty wavy red lines). I can&#39;t really tell when, but it can be related to the installation of .Net Framework 3.5 SP 1 or the MVC Beta (which I guess is unlikely). Furthermore have I installed and uninstalled both CodeRush and Resharper for evaluation purposes (decided not to keep either one of them).

Does anyone know the problem and how to restore this functionality again?

Visual Studio Editor does not underline errors anymore

As a follow-up to [this question][2], it&#39;s trying to find out how to do something like this which should be easy, that especially stops me from getting more used to using Emacs and instead starting up the editor I&#39;m already familiar with. I use the example here fairly often in editing multiple files.

In Ultraedit I&#39;d do Alt+s then p to display a dialog box with the options: Find (includes using regular expressions across multiple lines), Replace with, In Files/Types, Directory, Match Case, Match Whole Word Only, List Changed Files and Search Sub Directories. Usually I&#39;ll first use the mouse to click-drag select the text that I want to replace.

Using only Emacs itself (on Windows XP), without calling any external utility, how to replace all foo\nbar with bar\nbaz in `*.c` and `*.h` files in some folder and all folders beneath it. Maybe Emacs is not the best tool to do this with, but how can it be done easily with a minimal command?

Using Emacs to recursively find and replace in text files not already open

I&#39;ve tried [MiniBufExplorer](http://www.vim.org/scripts/script.php?script_id=159), but I usually end up with several windows showing it or close it altogether. What I&#39;d like is something like [LustyJuggler](http://www.vim.org/scripts/script.php?script_id=2050) with incremental search, the way I switch between buffers in Emacs. Surely there is a script like this?

How do you prefer to switch between buffers in Vim?

Given this line of code in C:

&gt; &lt;code&gt;printf(&quot;%3.0f\t%6.1f\n&quot;, fahr, **(**(5.0/9.0) * (fahr-32)**)**);&lt;/code&gt;

Is there a way to delete or yank from the first bold parenthesis to its matching parenthesis? I thought about **df)**, but that only will get you to just after the 9.0.

Is there a similar way to get vim to grab everything between matching braces, regardless of newlines?

Can you grab or delete between parentheses in vi/vim?

Well, hopefully the question is self-explanatory.

It&#39;s so easy to select a block of code and tab out, but how about the reverse?

Currently, I just search &amp; replace for whitespace at the beginning of the line. Anything faster?

Keyboard shortcut to &quot;untab&quot; (move a block of code to the left) in eclipse / aptana?

I understand that Aptana is built from Eclipse. I tried searching for the Package Explorer to enable viewing of .htaccess files inside the project but I can&#39;t find the Package Explorer.

Any help of the exact location on how to enable it will be excellent.
