php - Creating a comments page selection using AJAX data -

-

i decided go ajax route heck of it, learn it, , see how worked. want add page selection comments exceed, say, 10 posts.

i using codeigniter, , post have far:

controller:

    public function updatefilters()     {         $this->blurb_model->create_session_filter($_post['filters']);         $this->blurb_model->get_threads($_post['pagenum']);     }

model: 

    public function get_threads($page = 0)     {             $needpagehere = $page             [fetch threads]             [return threads / count / etc]     }

so goal display number of pages user. part done. have submit button displayed each page based on total count of items returned in "get_threads" model (code omitted relevance sake).

here ajax/javascript

focus lies on updatefilter function. use returned thread list construct html , post within div. works fine.

the problem want reuse updatefilters() function when user clicks on page button...but not working. want pass value of submit button updatefilter(pagenum) goes controller -> method, , can math, not work.

javascript: 

 function updatefilters(pagenum){         // selected filters         var html;         var = 0;         if (!pagenum)             {                 pagenum = 0             }         var $selected = $('#selectable').children('.ui-selected');         // create string has each filter separated pipe ("|")         var filters = $selected.map(function(){return this.id;}).get().join("\|");         $.ajax({             type: "post",             async: false,             url: 'welcome/updatefilters',             datatype: 'json',              data: { filters: filters, pagenum: pagenum },             success: function(data){                 var html = "";                 html += "<div id=board>"                 html += "<div class='board' id='table'>"                 html += "<div id='row'>header here</div>"                  var pages = math.ceil(data['num_threads']/10);                 var htmlpage = "<div class='pages'>"                 (i=1 ; < pages+1 ; i++)                     {                         htmlpage += "<li><input type='submit' id='page"+i+"' value='"+i+"' onclick='updatefilters(this.value);' /></li>"                     }                 htmlpage += "<div>"                     htmlpage += "</ul>";                 htmlpage += "</br></br></br>";                 html += htmlpage;                  (i=0 ; < data['threads'].length ; i++)                 {                     html += "<div id=row>";                     html += "   <div id='author' style='background: url("+data['threads'][i].location + ") no-repeat; background-position: center;'><p>"+data['threads'][i].username + "</p></div>";                     html += "   <div id='arrow'></div>";                     html += "   <div id='subject' title='"+ data['threads'][i].body +"'>";                     html += "       <a href=thread/" + data['threads'][i].slug + ">"+ data['threads'][i].subject +"</a><p>created: "+data['threads'][i].posttime+"</p></div>";                                         html += "   <div id='info'>";                     html += "       <div id='replies'>" + data['threads'][i].replies_num + "</div>";                     html += "       <div id='lastpost'>"+ data['threads'][i].lastreply+"</div>";                     html += "   </div>";                     html += "</div>";                 }                 html += "</div></div>";                 $('#board').html(html);             }         });     }    $(function() {     $( "#selectable" ).selectable({         selected: updatefilters       });     getactivesession();     function getactivesession(ev, ui){         var = 0;         var actfilter, strfilter;         var strfilterarray = new array();         $.ajaxsetup({cache: false})         $.ajax({         type: "post",           async: false,         url: 'welcome/getactivesession',          datatype: 'json',         success: function (data){             strfilter = json.stringify(data)             strfilterarray = strfilter.split(',')             (i=0 ; < strfilterarray.length ; i++) {                 strfilter = strfilterarray[i]                 strfilter = strfilter.replace(/[\[\]'"]+/g,'');                 var strfilterdash = strfilter.replace(/\s+/g, '-')                 actfilter = '#'+ strfilterdash                 $(actfilter).addclass('ui-selected')             }             updatefilters();         }         });     } });

this incredible learning experience myself, , huge if can spot problem , explain in understood manner. extremely new javascript , programming in general (which might explain ugliness of code).

thanks!

modify selected event callback.

$("#selectable").selectable({   // here event callback signature reference   selected: function(event, ui) {     updatefilters();   } });

you passing unexpected first parameter updatefilters function.

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
