  • Django throws 404 at generic views

    - by x0rg
    I'm trying to get the generic views for a date-based archive working in django. I defined the urls as described in a tutorial, but django returns a 404 error whenever I want to access an url with a variable (such as month or year) in it. It don't even produces a TemplateDoesNotExist-execption. Normal urls without variables work fine. Here's my urlconf: from django.conf.urls.defaults import * from zurichlive.zhl.models import Event info_dict = { 'queryset': Event.objects.all(), 'date_field': 'date', 'allow_future': 'True', } urlpatterns += patterns('django.views.generic.date_based', (r'events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, slug_field='slug',template_name='archive/detail.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-w]+)/$', 'object_detail', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$','archive_day',dict(info_dict,template_name='archive/list.html')), (r'^events/(?P<year>d{4})/(?P<month>[a-z]{3})/$','archive_month', dict(info_dict, template_name='archive/list.html')), (r'^events/(?P<year>)/$','archive_year', dict(info_dict, template_name='archive/list.html')), (r'^events/$','archive_index', dict(info_dict, template_name='archive/list.html')), ) When I access /events/2010/may/12/this-is-a-slug I should get to the detail.html template, but instead I get a 404. What am I doing wrong?

  • Java's equivalent to bisect in python

    - by systemsfault
    Hello all, Is there a java equivalent to python's bisect library? With python's bisect you can do array bisection with directions. For instance bisect.bisect_left does: Locate the proper insertion point for item in list to maintain sorted order. The parameters lo and hi may be used to specify a subset of the list which should be considered; by default the entire list is used.

  • [LaTeX] positions of page numbers, position of chapter headings, chapters AND Table of Contents, Ref

    - by kaikanmonaco
    I am writing my PhD thesis (120+ pages) in latex, the deadline is approaching and I am struggling with layout problems. I am using the documentstyle book. I am posting both problems in this one thread because I am not sure if the solution might be related to both problems or not. Problems are: 1.) The page numbers are mostly located on the top-right of each page (this is correct and where I want them to be). However, only on the first page of chapters and on the first page of what I call "special chapters", the page number is located bottom-centered. With "special chapters" I mean: List of Contents, List of Figures, List of Tables, References, Index. My university will not accept the thesis like this. The page number must ALWAYS be top-right one each page, even if the page is the first page of a chapter or the first page of something like the List of Contents. How can I fix this? 2.) On the first page of chapters and "special chapters" (List of Contents...), the chapter title is located far too low on the page. This is the standard layout of LaTeX with documentstyle book I think. However, the chapter title must start at the very top of the page! I.e. the same height as the normal text on the pages that follow. I mean the chapter title, not the header. I.e., if there is a chapter called "Chapter 1 Dynamics of foobar under mechanical stress" then that text has to start from the top the page, but right now it starts several centimeters below the top. How can I fix this? Have tried all kinds of things to no effect, I'd be very thankful for a solution! Thanks.

  • Strange behavior while returning csv file from spring controller

    - by Fanooos
    I working in a spring application which have an action method that returns a CSV file. This action works fine but in some cases it throws a predefined exception (MyAppException). I have another method that is annotated @ExceptionHandler(MyAppException.class) In the exception handler method I return another csv file but with different contents. The code that returns the csv file is almost the same in the two methods. List<String[]> list= new ArrayList<String[]>(); list.add(new String[]{ integrationRequestErrorLog.getErrorMessage(), Long.toString(integrationRequestErrorLog.getId()), Integer.toString(integrationRequestErrorLog.getErrorCode()) }); CSVWriter writer = new CSVWriter(response.getWriter(), ','); writer.writeAll(list); writer.close(); the difference between the two method is the list of contents. In the first method the file is returned normally while in the exception handler method I have a strange behavior. The exception handler method works fine with Opera browser while it gives me a 404 with FireFox. Opera browser give me 404 also but it download the file while firefox does not? Really I do not understand what is the difference here.

    I have 3 files: 1) cpf0.ml type string = char list type url = string type var = string type name = string type symbol = | Symbol_name of name 2) problem.ml: type symbol = | Ident of string 3) test.ml open Problem;; open Cpf0;; let symbol b = function | Symbol_name n -> Ident n When I combine test.ml: ocamlc -c test.ml. I received an error: This expression has type Cpf0.name = char list but an expression was expected of type string Could you please help me to correct it? Thank you very much EDIT: Thank you for your answer. I want to explain more about these 3 files: Because I am working with extraction in Coq to Ocaml type: cpf0.ml is generated from cpf.v : Require Import String. Definition string := string. Definition name := string. Inductive symbol := | Symbol_name : name -> symbol. The code extraction.v: Set Extraction Optimize. Extraction Language Ocaml. Require ExtrOcamlBasic ExtrOcamlString.

Could you please give me a good idea? how I would do in this case.

    I have a dict of lists in python: content = {88962: [80, 130], 87484: [64], 53662: [58,80]} I want to turn it into a list of the unique values [58,64,80,130] I wrote a manual solution, but it's a manual solution. I know there are more concise and more elegant way to do this with list comprehensions, map/reduce , itertools , etc. anyone have a clue ? content = {88962: [80, 130], 87484: [64], 53662: [58,80]} result = set({}) for k in content.keys() : for i in content[k]: result.add(i) # and list/sort/print just to compare the output r2 = list( result ) r2.sort() print r2

  • Why is my quick sort so slow?

    - by user513075
    Hello, I am practicing writing sorting algorithms as part of some interview preparation, and I am wondering if anybody can help me spot why this quick sort is not very fast? It appears to have the correct runtime complexity, but it is slower than my merge sort by a constant factor of about 2. I would also appreciate any comments that would improve my code that don't necessarily answer the question. Thanks a lot for your help! Please don't hesitate to let me know if I have made any etiquette mistakes. This is my first question here. private class QuickSort implements Sort { @Override public int[] sortItems(int[] ts) { List<Integer> toSort = new ArrayList<Integer>(); for (int i : ts) { toSort.add(i); } toSort = partition(toSort); int[] ret = new int[ts.length]; for (int i = 0; i < toSort.size(); i++) { ret[i] = toSort.get(i); } return ret; } private List<Integer> partition(List<Integer> toSort) { if (toSort.size() <= 1) return toSort; int pivotIndex = myRandom.nextInt(toSort.size()); Integer pivot = toSort.get(pivotIndex); toSort.remove(pivotIndex); List<Integer> left = new ArrayList<Integer>(); List<Integer> right = new ArrayList<Integer>(); for (int i : toSort) { if (i > pivot) right.add(i); else left.add(i); } left = partition(left); right = partition(right); left.add(pivot); left.addAll(right); return left; } }

I have tried to use an xsl:for-each statement but I am messing up the names/parameters. List is called mlc The list contains the fields: Title City Region Advisory DateCreated TT (calculated number field to find the number of minutes from the DateCreated to end of today which I intended to use the smallest to find the most recent) I have the list grouped by Region and it currently shows all the items for each city. I want to reduce to only the most recent advisory for each city.

  • JQuery Optimization: Is there any way to speed up the rendering of the FlexSelect control?

    - by Sephrial
    Greetings, I am new to jQuery, and I have a performance problem with the FlexSelect control where it takes about 5 seconds to render the dropdown control (in the renderDropdown() function). The dropdown list contains about 5000 element. I believe all the runtime is attributed to the following block of code: var list = this.dropdownList.html(""); $.each(this.results, function() { list.append($("<li/>").html(this.name)); }); Question: Are there any alternatives that would build this list of elements in a more inefficient manner?

  • Copy an array backwards? Array.Copy?

    - by daniel
    I have a List<T> that I want to be able to copy to an array backwards, meaning start from List.Count and copy maybe 5 items starting at the end of the list and working its way backwards. I could do this with a simple reverse for loop; however there is probably a faster/more efficient way of doing this so I thought I should ask. Can I use Array.Copy somehow? Originally I was using a Queue as that pops it off in the correct order I need, but I now need to pop off multiple items at once into an array and I thought a list would be faster.

  • Help me build a CouchDB mapreduce

    - by mit
    There are CouchDB documents that are list elements: { "type" : "el", "id" : "1", "content" : "first" } { "type" : "el", "id" : "2", "content" : "second" } { "type" : "el", "id" : "3", "content" : "third" } There is one document that defines the list: { "type" : "list", "elements" : ["2","1"] , "id" : "abc123" } As you can see the third element was deleted, it is no longer part of the list. So it must not be part of the result. Now I want a view that returns the content elements including the right order. The result could be: { "content" : ["second", "first"] } In this case the order of the elements is already as it should be. Another possible result: { "content" : [{"content" : "first", "order" : 2},{"content" : "second", "order" : 1}] } I started writing the map function: map = function (doc) { if (doc.type === 'el') { emit(doc.id, {"content" : doc.content}); //emit the id and the content exit; } if (doc.type === 'list') { for ( var i=0, l=doc.elements.length; i<l; ++i ){ emit(doc.elements[i], { "order" : i }); //emit the id and the order } } } This is as far as I can get. Can you correct my mistakes and write a reduce function? Remember that the third document must not be part of the result.

    I have a class that implements IComparable. public class MyClass : IComparable<MyClass> { public int CompareTo(MyClass c) { return this.whatever.CompareTo(c.whatever); } etc.. } I then can call the sort method of a generic list of my class List<MyClass> c = new List<MyClass>(); //Add stuff, etc. c.Sort(); and have the list sorted according to my comparer. How do i specify further comparers to sort my collection different ways according to the other properties of MyClass in order to let users sort my collection in a number of different ways?

  • Is it necessary to var scope loop variables in CFScript?

    - by Mel
    When using CFML and CF9 I usually var scope my loop variables; in this case local.i, for example: <cfloop list="#this.list#" index="local.i"> <cfif Len(local.i) GT 10> // do something </cfif> </cfloop> I recently started converting some stuff into CFScript, and (to my disappointment I found out that there is no way to loop over a list in CFScript) I'm wondering if I should still var scope my loop variables, and how: for (i = 1; LTE ListLen(this.list); i = i + 1 ) { if (Len(ListGetAt(this.list, i) GT 10)) { // do something } } Should I be doing local.i = 1 and local.i = local.i + 1 istead of the sample code in my example? Is it necessary? EDIT: I should also ask if the CFScript form of my CFML loop is correct; I ask because I just noticed that my CFML loop uses a , (comma and space) for the delimiter argument, which seems non-existence in the CFScript version of the loop.

  • back button android

    i am having trouble implementing the back button properly. all of the code snippets i have seen have not worked for me. what i am trying to do when i press the back button is just go back to the previous list. pretty much i have a list within a list and i just want it to go back to the previous list. how would i go about doing this? this is the list i have, every item has a separate list that it has. lets say you click on weapons, you then get a list of different weapon types and so on final String[] weapons = getResources().getStringArray(R.array.weapons); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, weapons)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { System.out.println("item clicked: "+weapons[position]); switch(position) { case 0: final String[] axes = getResources().getStringArray(R.array.axes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, axes)); break; case 1: final String[] clubs = getResources().getStringArray(R.array.clubs); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, clubs)); break; case 2: final String[] daggers = getResources().getStringArray(R.array.daggers); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, daggers)); break; case 3: final String[] great_axes = getResources().getStringArray(R.array.great_axes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_axes)); break; case 4: final String[] great_katana = getResources().getStringArray(R.array.great_katana); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_katana)); break; case 5: final String[] great_swords = getResources().getStringArray(R.array.great_swords); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_swords)); break; case 6: final String[] hand_to_hand = getResources().getStringArray(R.array.hand_to_hand); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, hand_to_hand)); break; case 7: final String[] katana = getResources().getStringArray(R.array.katana); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, katana)); break; case 8: final String[] polearms = getResources().getStringArray(R.array.polearms); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, polearms)); break; case 9: final String[] scythes = getResources().getStringArray(R.array.scythes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, scythes)); break; case 10: final String[] staves = getResources().getStringArray(R.array.staves); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, staves)); break; case 11: final String[] swords = getResources().getStringArray(R.array.swords); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, swords)); break; } } });

  • Nice way to break a reply up into pieces in ruby

    - by ChaosR
    Hello, I'm writing an IRCd. For this topic it doesn't really matter if you know much about IRC. Its a simple code style problem. Quick overview of the problem: No message may be longer than 512 characters If the message is more, it must be broken into pieces The NAMES reply sends all the nicknames of users on a channel, and quickly grows beyond 512 characters. I currently concocted this marvelous piece of code, it works perfectly. However, its just not "ruby-like". This piece of code is more what you expect in some piece of C code. # 11 is the number of all fixed characters combined in the reply pre_length = 11 + servername.length + mynick.length + channel.name.length list = [""] i = 0 channel.nicks.each do |nick, client| list[i+=1] = "" if list[i].length + nick.length + pre_length > 500 list[i] << "#{channel.mode_char(client)}#{client.nick} " end list.each { |l| send_numeric(RPL_NAMREPLY, channel.name, l.strip) } send_numeric(RPL_ENDOFNAMES, channel.name) So my question is, any ideas to do this more nicely? PS. code has been slightly modified to make it easier to understand out-of-context
