• How to make Unity's Dash save the results filtering?

  - by Vagrant232

  The dash can remember the settings for filtered results for the entire session, but not beyond that. Once the profile is logged out and back in the results would reset to their original settings; displaying all the results without filtering. How can I make the results filtering more permanent? IE: How to make the photo lens for instance always show photos from "This Computer" and not from Picasa or Facebook across sessions and not just temporarily?

• Is there a way to return a response every x seconds or so to a single http request?

  - by luis

  I'm wondering if it's possible to send a response every second or so to a single http request. Like for example the client makes an http request, then the server sends a space character every second. This could be never ending or with a limit, for example a minute. I think the word 'response' is misleading in this context, since I don't necessarily mean an http response. The whole http response could be composed of the space characters, which would mean a single http response to a single http request, except that it is a minute long. I tried chunked encoding but I don't think it works, or at least my implementation's wrong.

• RadGrid Custom Filter

  - by Aaron

  I'm trying to add a custom filter to my RadGrid. I have a column, vendNum, which I want to allow users to filter on multiple vendNums with a comma-separated list. Basically, I want the same functionality as an "in" statement in SQL (where vendNum in (X,Y,Z)). I followed the tutorial on this site and came up with the following code to place in my RadGrid1_ItemCommand event. protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) { if (e.CommandName == RadGrid.FilterCommandName) { Pair filterPair = (Pair)e.CommandArgument; switch (filterPair.Second.ToString()) { case "vendNum": TextBox tbPattern = (e.Item as GridFilteringItem)["vendNum"].Controls[0] as TextBox; if (tbPattern.Text.Contains(",")) { string[] values = tbPattern.Text.Split(','); if (values.Length >= 2) { e.Canceled = true; StringBuilder newFilter = new StringBuilder(); for (int i = 0; i < values.Length; i++) { if (i == values.Length - 1) newFilter.Append("[vendNum] = " + values[i]); else newFilter.Append("[vendNum] = " + values[i] + " OR "); } if (RadGrid1.MasterTableView.FilterExpression == "") RadGrid1.MasterTableView.FilterExpression = newFilter.ToString(); else RadGrid1.MasterTableView.FilterExpression = "((" + RadGrid1.MasterTableView.FilterExpression + ") AND (" + newFilter.ToString() + "))"; RadGrid1.Rebind(); } } break; default: break; } } } Doing this, though, keeps giving me an error "Expression Expected" when I try to filter with a comma separated list. I'm still able to filter a single vendNum. My FilterExpression does come out as expected. The code is failing on the RadGrid1.Rebind() statement. Has anyone dealt with this before? Any help is greatly appreciated. Thanks, Aaron

• Android addTextChangedListener onTextChanged not fired when Backspace is pressed?

  - by tsil

  I use addTextChangeListener to filter a list items. When the user enters a character on the editText, items are filtered based on user input. For example, if the user enters "stackoverflow", all items that contains "stackoverflow" are displayed. It works fine except that once the user press backspace to delete character(s), items are no longer filtered until he deletes all characters. For example, my items are: "stackoverflow 1", "stackoverflow 2", "stackoverflow 3", "stackoverflow 4". If user input is "stackoverflow", all items are displayed. If user input is "stackoverflow 1", only "stackoverflow 1" is displayed. Then user deletes the last 2 characters (1 and the space). User input is now "stackoverflow" but "stackoverflow 1" is still displayed and the other items are not displayed. This is my custom filter: private class ServiceFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); if (constraint == null || constraint.length() == 0) { // No filter implemented we return all the list results.values = origServiceList; results.count = origServiceList.size(); } else { List<ServiceModel> nServiceList = new ArrayList<ServiceModel>(); for (ServiceModel s : serviceList) { if (s.getName().toLowerCase().contains(constraint.toString().toLowerCase())) { nServiceList.add(s); } } results.values = nServiceList; results.count = nServiceList.size(); } return results; } @Override protected void publishResults(CharSequence constraint, FilterResults results) { if (results.count == 0) { notifyDataSetInvalidated(); } else { serviceList = (List<ServiceModel>) results.values; notifyDataSetChanged(); } } } And how I handle text change event: inputSearch.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { if (cs.length() >= 1) { mAdapter.getFilter().filter(cs); } else { mAdapter = new ServiceAdapter(MyActivity.this, R.layout.ussd_list_item, serviceList); listView.setAdapter(mAdapter); } } });

• Bayesian filtering for forum posts

  - by Andrew Davey

  Has anyone used a Bayesian filter to let forum members classify posts and so over time only display interesting posts? A Bayesian filter seems to work well for detecting email spam. Is this a viable approach to filter forum posts for users?

• Django filters - Using an AllValuesFilter (with a LinkWidget) on a ManyToManyField

  - by magnetix

  This is my first Stack Overflow question, so please let me know if I do anything wrong. I wish to create an AllValues filter on a ManyToMany field using the wonderful django-filters application. Basically, I want to create a filter that looks like it does in the Admin, so I also want to use the LinkWidget too. Unfortunately, I get an error (Invalid field name: 'operator') if I try this the standard way: # Models class Organisation(models.Model): name = models.CharField() ... class Sign(models.Model): name = models.CharField() operator = models.ManyToManyField('Organisation', blank=True) ... # Filter class SignFilter(LinkOrderFilterSet): operator = django_filters.AllValuesFilter(widget=django_filters.widgets.LinkWidget) class Meta: model = Sign fields = ['operator'] I got around this by creating my own filter with the many to many relationship hard coded: # Models class Organisation(models.Model): name = models.CharField() ... class Sign(models.Model): name = models.CharField() operator = models.ManyToManyField('Organisation', blank=True) ... # Filter class MyFilter(django_filters.ChoiceFilter): @property def field(self): cd = {} for row in self.model.objects.all(): orgs = row.operator.select_related().values() for org in orgs: cd[org['id']] = org['name'] choices = zip(cd.keys(), cd.values()) list.sort(choices, key=lambda x:(x[1], x[0])) self.extra['choices'] = choices return super(AllValuesFilter, self).field class SignFilter(LinkOrderFilterSet): operator = MyFilter(widget=django_filters.widgets.LinkWidget) I am new to Python and Django. Can someone think of a more generic/elegant way of doing this?

• Array filteration PHP

  - by Muhammad Sajid

  I have an array with values like: Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Birthday [childId] => 2 ) [1] => Array ( [parent] => Basic [parentId] => 1 [child] => Gender [childId] => 3 ) [2] => Array ( [parent] => Geo [parentId] => 10 [child] => Current City [childId] => 11 ) [3] => Array ( [parent] => Known me [parentId] => 5 [child] => My personality [childId] => 7 ) [4] => Array ( [parent] => Known me [parentId] => 5 [child] => Best life moment [childId] => 8 ) ) And I want to filter this array such that their filtration based on parent index, and the final result would be like: Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Array ( [0] => Birthday [1] => Gender ) ) [1] => Array ( [parent] => Geo [parentId] => 10 [child] => Array ( [0] => Current City ) ) [2] => Array ( [parent] => Known me [parentId] => 5 [child] => Array ( [0] => My personality [1] => Best life moment ) ) ) For that I coded : $filter = array(); $f = 0; for ($i=0; $i<count($menuArray); $i++) { $c = 0; for( $b = 0; $b < count($filter); $b++ ){ if( $filter[$b]['parent'] == $menuArray[$i]['parent'] ){ $c++; } } if ($c == 0) { $filter[$f]['parent'] = $menuArray[$i]['parent']; $filter[$f]['parentId'] = $menuArray[$i]['parentId']; $filter[$f]['child'][] = $menuArray[$i]['child']; $f++; } } But it results : Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Array ( [0] => Birthday ) ) [1] => Array ( [parent] => Geo [parentId] => 10 [child] => Array ( [0] => Current City ) ) [2] => Array ( [parent] => Known me [parentId] => 5 [child] => Array ( [0] => My personality ) ) ) Could anyone point out my missing LOC?

• How to apply multiple filters to sharepoint list

  - by Juraj Hajek

  Hi all, I have sharepoint list with several columns - month, year and some custom data. I want to provide 2 dropdowns to allow user select month and year to filter rows. I added "Choice Filter" webpart for month and set connection to list (this works). I added second "Choice Filter" for year and I wanted to do the same. However, I cannot set connection to list, because mylist is disabled in webpart menu "Edit-Connections-Send filter values to". How can I apply 2 filtering criteria? Thanks, Juraj

• HttpClient POST fails to submit the form + resulting string is cut-off (incomplete)

  - by Jayomat

  Hi, I'm writing an app to check for the bus timetable's. Therefor I need to post some data to a html page, submit it, and parse the resulting page with htmlparser. Though it may be asked a lot, can some one help me identify if 1) this page does support post/get (I think it does) 2) which fields I need to use? 3) How to make the actual request? this is my code so far: String url = "http://busspur02.aseag.de/bs.exe?Cmd=RV&Karten=true&DatumT=30&DatumM=4&DatumJ=2010&ZeitH=&ZeitM=&Suchen=%28S%29uchen&GT0=&HT0=&GT1=&HT1="; String charset = "CP1252"; System.out.println("startFrom: "+start_from); System.out.println("goTo: "+destination); //String tag.v List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("HTO", start_from)); params.add(new BasicNameValuePair("HT1", destination)); params.add(new BasicNameValuePair("GTO", "Aachen")); params.add(new BasicNameValuePair("GT1", "Aachen")); params.add(new BasicNameValuePair("DatumT", day)); params.add(new BasicNameValuePair("DatumM", month)); params.add(new BasicNameValuePair("DatumJ", year)); params.add(new BasicNameValuePair("ZeitH", hour)); params.add(new BasicNameValuePair("ZeitM", min)); UrlEncodedFormEntity query = new UrlEncodedFormEntity(params, charset); HttpPost post = new HttpPost(url); post.setEntity(query); InputStream response = new DefaultHttpClient().execute(post).getEntity().getContent(); // Now do your thing with the facebook response. String source = readText(response,"CP1252"); Log.d(TAG_AVV,response.toString()); System.out.println("STREAM "+source); EDIT: This is my new code: try { HttpClient client = new DefaultHttpClient(); String getURL = "http://busspur02.aseag.de/bs.exe?SID=5FC39&ScreenX=1440&ScreenY=900&CMD=CR&Karten=true&DatumT="+day+"&DatumM="+month+"&DatumJ="+year+"&ZeitH="+hour+"&ZeitM="+min+"&Intervall=60&Suchen=(S)uchen&GT0=Aachen&T0=H&HT0="+start_from+"&GT1=Aachen&T0=H&HT1="+destination+""; HttpGet get = new HttpGet(getURL); HttpResponse responseGet = client.execute(get); HttpEntity resEntityGet = responseGet.getEntity(); if (resEntityGet != null) { //do something with the response Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet)); } } catch (Exception e) { e.printStackTrace(); } But the output file is cut-off. If I do the same request in a browser I get like 14 different routes.

• SSL / HTTP / No Response to Curl

  - by Alex McHale

  I am trying to send commands to a SOAP service, and getting nothing in reply. The SOAP service is at a completely separate site from either server I am testing with. I have written a dummy script with the SOAP XML embedded. When I run it at my local site, on any of three machines -- OSX, Ubuntu, or CentOS 5.3 -- it completes successfully with a good response. I then sent the script to our public host at Slicehost, where I fail to get the response back from the SOAP service. It accepts the TCP socket and proceeds with the SSL handshake. I do not however receive any valid HTTP response. This is the case whether I use my script or curl on the command line. I have rewritten the script using SOAP4R, Net::HTTP and Curb. All of which work at my local site, none of which work at the Slicehost site. I have tried to assemble the CentOS box as closely to match my Slicehost server as possible. I rebuilt the Slice to be a stock CentOS 5.3 and stock CentOS 5.4 with the same results. When I look at a tcpdump of the bad sessions on Slicehost, I see my script or curl send the XML to the remote server, and nothing comes back. When I look at the tcpdump at my local site, I see the response just fine. I have entirely disabled iptables on the Slice. Does anyone have any ideas what could be causing these results? Please let me know what additional information I can furnish. Thank you! Below is a wire trace of a sample session. The IP that starts with 173 is my server while the IP that starts with 12 is the SOAP server's.

• How to disable windows server 2008 timestamp response

  - by Cal

  Posted this question on stackoverflow but then got instructed to post it here: I was using Rapid7's Nexpose to scan one of our web servers (windows server 2008), and got a vulnerability for timestamp response. According to Rapid7, timestamp response shall be disabled: http://www.rapid7.com/db/vulnerabilities/generic-tcp-timestamp So far I have tried several things: Edit the registry, add a "Tcp1323Opts" key to HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, and set it to 0. http://technet.microsoft.com/en-us/library/cc938205.aspx Use this command: netsh int tcp set global timestamps=disabled Tried powershell command: Set-netTCPsetting -SettingName InternetCustom -Timestamps disabled (got error: Set-netTCPsetting : The term 'Set-netTCPsetting' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.) None of above attempts was successful, after re-scan we still got the same alert. Rapid7 suggested using a firewall that's capable of blocking it, but we want to know if there is a setting on windows to achieve it. Is it through a specific port? If yes, what is the port number? If not, could you suggest a 3rd party firewall that is capable of blocking it? Thank you very much.

• BlazeDS first response is VERY SLOW

  - by chibban

  Hi everyone, I have a very strange an annoying problem: I have an appliaction written in Flex 3, with BlazeDS 3.2 and Java in the backend. I'm actually using a portal (liferay) to display portlets that contain Flex movies. When I hit a refresh button on my page, all the Flex movies send a RemoteObject request to the server (using BlazeDS), which should go to java classes and invoke a method (standard BlazeDS usage I 'm guessing). I'm experiencing VERY slow response (14 minutes) on the first hit, while the following hits are much faster. I've enabled the BlazeDS logging (logging level="All") and I also have debug prints coming from my java classes. I also use the "showBusyCursor" attribute for the RemoteObject - so I can see indication of the request being sent from the flex movie. Here is what I see: I hit the refresh button Each movie invokes a RemoteObject request I see a busy sign - in all the movies I see nothing in the log - no BlazeDS prints and no Java prints Wait 14 minutes or so I see BlazeDS prints followed by Java prints I see data populating my flex movies. The really weird thing is that I have the same "application" installed in 4 different computers (on my laptop and in 3 other unix machines), 3 of these installations work well (good response times) and only 1 has the issue I'm describing. I've tried many things, but everything failed. I'd be really happy to get some advice on this. Thanks

• Squid3 not caching simple request and response

  - by Nick Spacek

  Hi folks, I've pared down my squid.conf to try to figure this out: http_port 80 accel defaultsite=host.to.cache cache_peer ip.to.cache parent 80 0 no-query originserver acl our_sites dstdomain host.to.cache http_access allow our_sites refresh_pattern . 1 20% 4320 Requests are being proxied correctly, so that's a start. Here's a request: GET http://host.to.cache/path?some_param=true Accept: */* Accept-Charset: ISO-8859-1,utf-8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en Connection: keep-alive Host: host.to.cache User-Agent: myuseragent And the response: Connection: keep-alive Content-Length: 585 Content-Type: application/xml Date: Thu, 06 Jan 2011 18:33:11 GMT Via: 1.0 localhost (squid/3.0.STABLE19) X-Cache: MISS from localhost X-Cache-Lookup: MISS from localhost:80 The response has no caching-related headers, but I thought that refresh_pattern would set a default behavior for responses without caching-related headers. For my test, I wanted to cache everything for one minute at minimum. Am I missing something obvious? I did take a peek at this question: Squid isn't caching ...and ran through the page here: http://www.mnot.net/cache_docs/ briefly, but didn't see anything relevant (not to say that there isn't, I could have missed something). Thanks for any help.

• PHP Causing Segmentation Fault & Apache Blank Response

  - by Joe

  I recently updated a Debian Lenny server to php 5.3,5 using the dotdeb source. Soon after doing so certain (but not all) sites on the server stopped responding to requests. A blank response would be returned - no headers, no content, nothing. I found this related question on stackoverflow which seems to describe something similar and used the same code the user had in their answer to see if I could replicate the issue: <?php class A { public function __construct() { new B; } } class B { public function __construct() { new A; } } new A; print 'Loaded Class A'; ?> This triggered the problem - the page returned absolutely nothing despite the original question stating this was fixed in PHP 5.5.0. No CPU block as you'd expect, no wait, just an almost instant zero response. I then ran this same code from the cli (php -f test.php) and the only output I got was 'Segmentation fault'. Tailing the kernel log I've spotted: Feb 16 07:04:06 creature kernel: [192203.269037] php[17710] general protection ip:76ef37 sp:7fff155e9bb0 error:0 in php5[400000+870000] Feb 16 08:57:31 creature kernel: [199639.699854] apache2[31136]: segfault at 7fff13a84fe0 ip 7f730514ea40 sp 7fff13a85008 error 6 in libphp5.so[7f7304ce8000+915000] All extremely odd and I'm not sure what it's pointing to/what I should do to debug this further. As I said some sites work but code such as the above definitely trigger it. Not that the sites I want to server have code like that - it's just an example. Any help is much appreciated!

• Understanding tcptraceroute versus http response

  - by kojiro

  I'm debugging a web server that has a very high wait time before responding. The server itself is quite fast and has no load, so I strongly suspect a network problem. Basically, I make a web request: wget -O/dev/null http://hostname/ --2013-10-18 11:03:08-- http://hostname/ Resolving hostname... 10.9.211.129 Connecting to hostname|10.9.211.129|:80... connected. HTTP request sent, awaiting response... 200 OK Length: unspecified [text/html] Saving to: ‘/dev/null’ 2013-10-18 11:04:11 (88.0 KB/s) - ‘/dev/null’ saved [13641] So you see it took about a minute to give me the page, but it does give it to me with a 200 response. So I try a tcptraceroute to see what's up: $ sudo tcptraceroute hostname 80 Password: Selected device en2, address 192.168.113.74, port 54699 for outgoing packets Tracing the path to hostname (10.9.211.129) on TCP port 80 (http), 30 hops max 1 192.168.113.1 0.842 ms 2.216 ms 2.130 ms 2 10.141.12.77 0.707 ms 0.767 ms 0.738 ms 3 10.141.12.33 1.227 ms 1.012 ms 1.120 ms 4 10.141.3.107 0.372 ms 0.305 ms 0.368 ms 5 12.112.4.41 6.688 ms 6.514 ms 6.467 ms 6 cr84.phlpa.ip.att.net (12.122.107.214) 19.892 ms 18.814 ms 15.804 ms 7 cr2.phlpa.ip.att.net (12.122.107.117) 17.554 ms 15.693 ms 16.122 ms 8 cr1.wswdc.ip.att.net (12.122.4.54) 15.838 ms 15.353 ms 15.511 ms 9 cr83.wswdc.ip.att.net (12.123.10.110) 17.451 ms 15.183 ms 16.198 ms 10 12.84.5.93 9.982 ms 9.817 ms 9.784 ms 11 12.84.5.94 14.587 ms 14.301 ms 14.238 ms 12 10.141.3.209 13.870 ms 13.845 ms 13.696 ms 13 * * * … 30 * * * I tried it again with 100 hops, just to be sure – the packets never get there. So how is it that the server does respond to requests via http, even after a minute? Shouldn't all requests just die? I'm not sure how to proceed debugging why this server is slow (as opposed to why it responds at all).

• Force request to miss cache but still store the response

  - by Tom Marthenal

  I have a slow web app that I've placed Varnish in front of. All of the pages are static (they don't vary for a different user), but they need to be updated every 5 minutes so they contain recent data. I have a simple script (wget --mirror) that crawls the entire website every 15 minutes. Each crawl takes about 5 minutes. The point of the crawl is to update every page in the Varnish cache so that a user never has to wait for the page to generate (since all pages have been generated recently thanks to the spider). The timeline looks like this: 00:00:00: Cache flushed 00:00:00: Spider starts crawling to update cache with new pages 00:05:00: Spider finishes crawling, all pages are updated until 1:15 A request that comes in between 0:00:00 and 0:05:00 might hit a page that hasn't been updated yet, and will be forced to wait a few seconds for a response. This isn't acceptable. What I'd like to do is, perhaps using some VCL magic, always foward requests from the spider to the backend, but still store the response in the cache. This way, a user will never have to wait for a page to generate since there is no 5-minute window in which parts of the cache are empty (except perhaps at server startup). How can I do this?

• Empty $upstream_http_location variable if response was cached

  - by Ivaldi

  I would like to cache the response of an redirect. (Cache the request to some site which returns a redirect and cache the second request which returns the actual content.) So far my config looks like this: location = /proxy { error_page 301 302 307 = @redir; resolver 8.8.8.8; proxy_pass $arg_url; proxy_intercept_errors on; proxy_cache pcache; proxy_cache_key $arg_url; proxy_cache_valid 200 301 302 307 1d; proxy_cache_min_uses 1; proxy_ignore_client_abort on; proxy_ignore_headers Set-Cookie Expires Cache-Control; } location @redir { resolver 8.8.8.8; # we need to assign $upstream_http_location to another var in order to use it with proxy_pass set $target $upstream_http_location; proxy_pass $target; proxy_cache predirects; proxy_cache_key $upstream_http_location; proxy_cache_valid 200 301 302 307 1d; proxy_cache_min_uses 1; proxy_ignore_headers Set-Cookie Expires Cache-Control; } It works for the first request or without the 30x codes for proxy_cache_valid in the /proxy part, but $target and $upstream_http_location are empty, if the response was cached. Is there a nice solution to cache both requests? Thanks!

• Filter, sort and paginate in Codeigniter

  - by Babak

  Ive recently started using CodeIgniter as I was searching for a very lightweight framework and it seemed to come up as a top choice. I am new to the whole MVC thing, enjoying it but am stuck with something which seems very simple. I am coding a CMS and need a way to filter, sort and paginate the results. I am used to doing it with querystrings, so I would have something along the lines of: articles.php?order=title&sort=desc&filter=articletitle&page=5 I have no idea how I would go about doing this in CI so I just turned on the EnableQueryStrings in the config and it works fine, but i am getting the feeling its probably not the most elegant solution. I suppose I could have index.php/articles/index/order/title/sort/desc/filter/articletitle/page/5 but to me this seems very inflexible, what if for example i dont need to sort, how would i make sure i am looking at the correct uri segment? any ideas?

• LDAP filter not being considered

  - by Ricky

  Hi there. I am performing an LDAP search query in C like so; ldap_search_ext_s(ld, BASEDN, SCOPE, FILTER, attrs, 0, NULL, NULL, NULL, LDAP_NO_LIMIT, &res); My search performs fine except when I try to specify FILTER to be; #define FILTER "uid=*", that is, when I try to run a search for all LDAP entries with a uid. Unfortunately my code just returns the first entry for each result that it finds. So, my code might find 50 results, but will return the first entry 50 times. Can anyone suspect what I might be doing wrong here? EDIT: I am stepping through my results like so: for (msg = ldap_first_message(ld, res); msg != NULL; msg = ldap_next_message(ld, msg)) Any help is really appreciated. Ricky.

• How to filter a dataview

  - by dboarman-FissureStudios

  I have a dataview that contains a list of tables. I am reading in a list of values that I then want to apply as a filter to this dataview. The list of values is actually in the form of "table1, table2, table3". So I thought I would be able to use this as a filter on my dataview. SqlOp.CommandText = "select name from dbo.sysobjects where xtype='u'"; SqlOp.ExecuteDataReader(); DataView dv = SqlOp.GetDataAsDataView(); SqlOp.CloseConnection(); Returns a list of all the tables in a dataview. Any help on how to filter this dataview? Edit: Not sure if I was completely clear in what I seek to accomplish. To clarify, I am trying to figure out how/if .RowFilter will help me in filtering this dataview. Something like: dv.RowFilter = "name IN (table1, table2, table3)" // I know this doesn't work

• Django QuerySet filter + order_by + limit

  - by handsofaten

  So I have a Django app that processes test results, and I'm trying to find the median score for a certain assessment. I would think that this would work: e = Exam.objects.all() total = e.count() median = int(round(total / 2)) median_exam = Exam.objects.filter(assessment=assessment.id).order_by('score')[median:1] median_score = median_exam.score But it always returns an empty list. I can get the result I want with this: e = Exam.objects.all() total = e.count() median = int(round(total / 2)) exams = Exam.objects.filter(assessment=assessment.id).order_by('score') median_score = median_exam[median].score I would just prefer not to have to query the entire set of exams. I thought about just writing a raw MySQL query that looks something like: SELECT score FROM assess_exam WHERE assessment_id = 5 ORDER BY score LIMIT 690,1 But if possible, I'd like to stay within Django's ORM. Mostly, it's just bothering me that I can't seem to use order_by with a filter and a limit. Any ideas?
