  • How can i change a jquery plugin's option value with my value?

    - by Pandiya Chendur
    I have just jquery pagination plugin to work... But what happens is when i click page number 2 i get the first page and when i click 3 i get second page and so on.... My initial page my current page value changes to 0 instead 1 this causes the problem... My plugin has this, jQuery.fn.pagination = function(maxentries, opts){ opts = jQuery.extend({ items_per_page:10, num_display_entries:10, current_page:0, num_edge_entries:0, link_to:"#", prev_text:"Prev", next_text:"Next", ellipse_text:"...", prev_show_always:true, next_show_always:true, callback:function(){return false;} },opts||{}); current_page is set to 0 ... I have modified the current page value in my jquery function but it doesn't seem to work.... <script type="text/javascript"> var itemsPerPage = 5; var maxNumberOfElementsHere = 17; $(document).ready(function() { getRecordspage(1, itemsPerPage); $(".pager").pagination(maxNumberOfElementsHere, { callback: getRecordspage, current_page: 1, // Look here i have changed this but it doesn't work... items_per_page: itemsPerPage, num_display_entries: 5, next_text: 'Next', prev_text: 'Prev', num_edge_entries: 1 }); }); </script>

  • How would I change this Query builder from Kohana 2.4 to Kohana 3?

    - by Thorpe Obazee
    I have had this website built for a few months and I am just getting on Kohana 3. I'd just like to convert this K2.4 query builder to K3 query builder. return DB::select(array('posts.id', 'posts.created', 'posts.uri', 'posts.price', 'posts.description', 'posts.title', 'image_count' => db::expr('COUNT(images.id)'))) ->from('posts') ->join('images')->on('images.post_id', '=', 'posts.id') ->group_by(array('posts.id')) ->order_by('posts.id', 'DESC') ->limit($limit) ->offset($offset) ->execute();

  • How can I change the Python that my Django project is using?

    - by Burak
    I have 2 versions installed in my server. I used virtualenv to install Python 2.7. I am using WSGI to deploy my project. WSGIPythonPath /home/ENV/lib/python2.7/site-packages WSGIScriptAlias / /var/www/html/my_project/wsgi.py My http.conf is like that. python -V gives Python 2.7.3 But in my projects Debug window, it says Django is using 2.6.8. Where am I wrong? UPDATE: Here is my wsgi file import os import sys sys.path.append('/var/www/html') os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() Python Version: 2.6.8 Python Path: ['/home/ENV/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/home/ENV/lib/python2.7/site-packages/pip-1.1-py2.7.egg', '/home/ENV/lib/python2.7/site-packages/Django-1.4-py2.7.egg', '/home/ENV/lib/python2.7/site-packages', '/usr/lib/python2.6/site-packages/pip-1.1-py2.6.egg', '/usr/lib/python2.6/site-packages/django_transmeta-0.6.7-py2.6.egg', '/usr/lib/python2.6/site-packages/ipython-0.13-py2.6.egg', '/usr/lib/python2.6/site-packages/virtualenv-1.7.2-py2.6.egg', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages', '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info', '/var/www/html'] In my error_log of httpd: [Tue Jul 10 20:51:29 2012] [error] python_init: Python version mismatch, expected '2.6.7', found '2.6.8'.

  • More elegant way to make a C++ member function change different member variables based on template p

    - by Eric Moyer
    Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?

  • Does the concept of "magic number" change from language to language?

    - by Gerardo Marset
    Take the following code in C/C++, for example: int foo[] = {0, 0, 0, 0}; No magic numbers, right? Now, the Python "equivalent" of that would be: foo = [0, 0, 0, 0] Still no magic numbers. However, in Python, that same thing can be written like this: foo = [0] * 4 And now we DO have a magic number. Or do we? I'm guessing this and other similar things are present on these and other languages.

  • How can I change what happens when "enter" key is pressed on a DataGridView?

    - by SO give me back my rep
    when I am editing a cell and press enter the next row is automatically selected, I want to stay with the current row... I want to happen nothing except the EndEdit. I have this: private void dtgProductos_CellEndEdit(object sender, DataGridViewCellEventArgs e) { dtgProductos[e.ColumnIndex, e.RowIndex].Selected = true; //this line is not working var index = dtgProductos.SelectedRows[0].Cells.IndexOf(dtgProductos.SelectedRows[0].Cells[e.ColumnIndex]); switch (index) { case 2: { dtgProductos.SelectedRows[0].Cells[4].Selected = true; dtgProductos.BeginEdit(true); } break; case 4: { dtgProductos.SelectedRows[0].Cells[5].Selected = true; dtgProductos.BeginEdit(true); } break; case 5: { btnAddProduct.Focus(); } break; default: break; } } so when I edit a row that is not the last one I get this error: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

  • Is it bad practice to change state inside of an if statement?

    - by Benjamin
    I wrote some code that looks similar to the following: String SKIP_FIRST = "foo"; String SKIP_SECOND = "foo/bar"; int skipFooBarIndex(String[] list){ int index; if (list.length >= (index = 1) && list[0].equals(SKIP_FIRST) || list.length >= (index = 2) && (list[0] + "/" + list[1]).equals(SKIP_SECOND)){ return index; } return 0; } String[] myArray = "foo/bar/apples/peaches/cherries".split("/"); print(skipFooBarIndex(myArray); This changes state inside of the if statement by assigning index. However, my coworkers disliked this very much. Is this a harmful practice? Is there any reason to do it?

  • By passing div id, can i change target of text replacement?

    - by crosenblum
    I am using the code below to replace text inside a div. But I need to loop through a specific div, instead of everything on the page, that is the div's text nodes... I just do not understand how to refer to the div in the code below. (function (parent) { var childs = parent.childNodes; // if there are children to this if (childs && childs.length) { // loop through each text node for (var i = 0, node; node = childs[i]; i++) {

  • Where do I change the height of a navigationBar for an iPhone app?

    - by Tony
    In my applicationDidFinishLaunching I set up a UINavigationController: - (void)applicationDidFinishLaunching:(UIApplication *)application { navController = [[UINavigationController alloc] init]; [[navController navigationBar] setFrame:CGRectMake(0.0,0.0,320.0,20.0)]; ... } As you can see, I am trying to make the navigation controller's height 20px. However, this is not working. I would imagine setFrame must be the correct function but I am not calling it in the right place. I realize that other questions on SO are similar to mine, but I think setting the navigationBar height should be possible if it responds to setFrame...right? Also, anyone know the default height of the navigationBar? Thanks!

  • Why does Windows 7 change encoding of characters in runtime?

    - by LukLed
    I have a delphi form: and my code: when I run this form in Windows 7, I see: In design time, form had polish letters in first label, but it doesn't have them in runtime. It looks ok on Vista or Windows XP. When I set caption of second label in code, everything works fine and characters are properly encoded. First 5 codes of top label on Windows 7: 65 97 69 101 83 First 5 codes of top label on Windows Vista/XP: 165 185 202 234 140 First 5 codes of bottom label on every system: 165 185 202 234 140 Windows 7 changes encoding, why? My system settings seem to be ok. I have proper language set for non-unicode applications in control panel.

  • How to change password hashing algorithm when using spring security?

    - by harry
    I'm working on a legacy Spring MVC based web Application which is using a - by current standards - inappropriate hashing algorithm. Now I want to gradually migrate all hashes to bcrypt. My high level strategy is: New hashes are generated with bcrypt by default When a user successfully logs in and has still a legacy hash, the app replaces the old hash with a new bcrypt hash. What is the most idiomatic way of implementing this strategy with Spring Security? Should I use a custom Filter or my on AccessDecisionManager or …?

  • UIScrollView - with paging enabled, can I "change" the page width?

    - by Mike McMaster
    What's the simplest way to have a scroll view (with pagingEnabled set to YES) have a page width set to something other than the scroll view's bounds? Let me give an example. Suppose I have a scroll view with 10 items, each 150 pixels wide, and my scroll view is 300 pixels wide. If I start with views 1 and 2 visible and scroll horizontally to the right, I want the next "page" to show items 2 and 3. If I scroll one more page to the right, I would see items 3 and 4. Has anyone done this? If not, what strategy would you use?
