  • Working With Feeds and Lists

    - by Nathan Campos
    I'm using a ListView component to list up some informations at a RSS feed, but when the user clicks the row, I want to change into a detailed view of that RSS Item, so far I've done this: function parseFeed(feed) { var html = ""; for(var i = 0; i < feed.items.length && i < 5; i++) { var item = feed.items[i]; var title = item.title; html += "\n<li onClick='goDetailed()'>\n"; html += "<h3><a href='#' class='ui-link-inherit'>" + title + "</a></h3>\n"; html += "<p>" + item.description + "</p>\n"; html += "</li>"; } $("#dList").append(html); $("#dList").listview('refresh'); } function goDetailed() { $.mobile.changePage($('#detailedPage')); } One of my problems is that the Back button won't come back(it does nothing). My other question is how I can pass the item.title, item.description, item.link and item.updated of the selected row(feed item) to some <div data-role="content">'s at the detail page.

  • Is it Possible to Use Constraints on Hierarchical Data in a Self-Referential Table?

    - by pbarney
    Suppose you have the following table, intended to represent hierarchical data: +--------+-------------+ | Field | Type | +--------+-------------+ | id | int(10) | | parent | int(10) | | name | varchar(45) | +--------+-------------+ The table is self-referential in that the parent_id refers to id. So you might have the following data: +----+--------+---------------+ | id | parent | name | +----+--------+---------------+ | 1 | 0 | fruit | | 2 | 0 | vegetable | | 3 | 1 | apple | | 4 | 1 | orange | | 5 | 3 | red delicious | | 6 | 3 | granny smith | | 7 | 3 | gala | +----+--------+---------------+ Using MySQL, I am trying to impose a (self-referential) foreign key constraint upon the data to cascade on update and prevent deletion of a record if it has any "children." So I used the following: CREATE TABLE `test`.`fruit` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `parent` INT(10) UNSIGNED, `name` VARCHAR(45) NOT NULL, PRIMARY KEY (`id`), CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT ) ENGINE = InnoDB; From what I understand, this should fit my requirements. (And parent must default to null to allow insertions, correct?) The problem is, if I change the id of a record, it will not cascade: Cannot delete or update a parent row: a foreign key constraint fails (`test`.`fruit`, CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE) What am I missing? Feel free to correct me if my terminology is screwed up... I'm new to constraints.

  • I have created a PHP script and I am lacking to extract the primary key, I have given flow below, pl

    - by Parth
    I am using MySQL DB, working for Joomla, My requirement is tracking the activity like insert/update/delete on any table and store it in another audit table using triggers, i.e. I am doing Auditing. DB's table structure: Few tables dont have any PK nor auto increment key Flow of my script is : I fetch out all table from DB. I check whether the table have any trigger or not. If yes then it moves to check nfor next table and so on. If it does'nt find any trigger then it creates the triggers for the table, such that, -it first checks if the table has any primary key or not(for inserting in Tracking audit table for every change made) if it has the primary key then it uses it further in creation of trigger. if it doesnt find any PK then it proceeds further in creating the trigger without inserting any id in audit table Now here, My problem is I need the PK every time so that I can record the id of any particular table in which the insert/update/delete is performed, so that further i can use this audit track table to replicate in production DB.. Now as I haave mentioned earlier that I am not available with PK/auto-incremented in some table, then what should I do get the particular id in which change is done? please guide me...GEEKS!!!

  • Write to memory buffer instead of file with libjpeg?

    - by Richard Knop
    I have found this function which uses libjpeg to write to a file: int write_jpeg_file( char *filename ) { struct jpeg_compress_struct cinfo; struct jpeg_error_mgr jerr; /* this is a pointer to one row of image data */ JSAMPROW row_pointer[1]; FILE *outfile = fopen( filename, "wb" ); if ( !outfile ) { printf("Error opening output jpeg file %s\n!", filename ); return -1; } cinfo.err = jpeg_std_error( &jerr ); jpeg_create_compress(&cinfo); jpeg_stdio_dest(&cinfo, outfile); /* Setting the parameters of the output file here */ cinfo.image_width = width; cinfo.image_height = height; cinfo.input_components = bytes_per_pixel; cinfo.in_color_space = color_space; /* default compression parameters, we shouldn't be worried about these */ jpeg_set_defaults( &cinfo ); /* Now do the compression .. */ jpeg_start_compress( &cinfo, TRUE ); /* like reading a file, this time write one row at a time */ while( cinfo.next_scanline < cinfo.image_height ) { row_pointer[0] = &raw_image[ cinfo.next_scanline * cinfo.image_width * cinfo.input_components]; jpeg_write_scanlines( &cinfo, row_pointer, 1 ); } /* similar to read file, clean up after we're done compressing */ jpeg_finish_compress( &cinfo ); jpeg_destroy_compress( &cinfo ); fclose( outfile ); /* success code is 1! */ return 1; } I would actually need to write the jpeg compressed image just to memory buffer, without saving it to a file, to save time. Could somebody give me an example how to do it? I have been searching the web for a while but the documentation is very rare if any and examples are also difficult to come by.

  • How to add files to a document library in a site definition in SharePoint 2007?

    - by jaloplo
    Hi all, I'm doing a site definition for SharePoint 2007. When the site is created, a document library called "Folder2" is created also. Now, I need to add some documents to this document library and appear as items in the document library standard views. My code is: <Lists> <List FeatureId="00bfea71-e717-4e80-aa17-d0c71b360101" Type="101" Title="Folder2" Url="Folder2"> <Data> <Rows> <Row> <Field Name="Name">MyFile.txt</Field> <Field Name="Title">MyFile.txt</Field> <Field Name="FileLeafRef">MyFile.txt</Field> </Row> </Rows> </Data> </List> </Lists> When I see the items of the Document Library there is one element with title "1_". Does anybody know how to add files in a site definition? The onet.xml I used is the same as blank site. Thanks!!!

  • iOS Cell Label link

    - by hart1994
    Hi I am new to iOS programming and I need a little help. I have a table view cell which is populated by data from a .plist file. I need to be able to make a link within one of the cells. How could I do this? Here is the code which is loading the data into the cells: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CustomTableCell"; static NSString *CellNib = @"DetailViewCell"; DetailViewCell *cell = (DetailViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellNib owner:self options:nil]; cell = (DetailViewCell *)[nib objectAtIndex:0]; } cell.accessoryType = UITableViewCellAccessoryNone; cell.cellTitleLabel.textColor = [UIColor blackColor]; cell.cellTitleLabel.font = [UIFont systemFontOfSize:20.0]; cell.cellSubtitleLabel.textColor = [UIColor darkGrayColor]; informations = [[NSArray alloc] initWithObjects:@"City", @"Country", @"State", @"History", @"Link", nil]; subtitles = [[NSArray alloc] initWithObjects:titleString, subtitleString, stateString, populationString, @"Link", nil]; cell.cellTitleLabel.text = [informations objectAtIndex:indexPath.row]; cell.cellSubtitleLabel.text = [subtitles objectAtIndex:indexPath.row]; return (DetailViewCell *) cell; } For the cell "Link" I need it to open a url which is stored in the .plist file. How could i do this? Many thanks Ryan PS: I'm a newbie at this stuff, so be descriptive. Thanks

  • Crosstab with multiple items

    - by Michael Wexler
    In SPSS, it is (relatively) easy to create a cross tab with multiple variables using the factors as the table heading. So, something like the following (made up data, etc.). Q1, Q2, and Q3 each have either a 1, a 2, or a 3 for each person. 1 (very Often) 2 (Rarely) 3 (Never) Q1. Likes it 12 15 13 Q2. Recommends it 22 11 10 Q3. Used it 22 12 9 In SPSS, one can even request row, column, or total percentages. I've tried table(), ftable(), xtab(), CrossTable() from gmodels, and CrossTable() from descr, and none of these can handle (afaik) multiple variables; they mostly seem to handle 1 variable crossed with another variable, and the 3rd creates layers. Is there a package with some good cross tabbing/table examples that I could use to figure this out? I'm sure I'm missing something simple, so I appreciate you pointing out what I missed. Perhaps I have to generate each row as a separate list and then make a dataframe and print the dataframe?

  • Using tarantula to test a Rails app

    - by Benjamin Oakes
    I'm using Tarantula to test a Rails app I'm developing. It works pretty well, but I'm getting some strange 404s. After looking into it, Tarantula is following DELETE requests (destroy actions on controllers) throughout my app when it tests. Since Tarantula gets the index action first (and seems to keep a list of unvisited URLs), it eventually tries to follow a link to a resource which it had deleted... and gets a 404. Tarantula is right that the URL doesn't exist anymore (because it deleted the resource itself). However, it's flagging it as an error -- that's hardly the behavior I would expect. I'm basically just using the Rails scaffolding and this problem is happening. How do I prevent Tarantula doing this? (Or, is there a better way of specifying the links?) Updates: Still searching, but I found a relevant thread here: http://github.com/relevance/tarantula/issues#issue/3 Seems to be coming from relying on JS too much, in a way (see also http://thelucid.com/2010/03/15/rails-can-we-please-have-a-delete-action-by-default/)

  • Partioning with Hibernate

    - by Alex
    Hello, We have a requirement to delete data in the range of 200K from database everyday. Our application is Java/JEE based using Oracle DB and Hibernate ORM tool. We explored various options like Hibernate batch processing Stored procedure Database partitioning Our DBA suggests database partitioning is the best way to go, so we can easily recreate and drop the partitioned table everyday. Now the issue is we have 2 kinds of data, one which we want to delete everyday and the other which we want to keep it. Suppose this data is stored in table "Trade". Now with partitioning, we have 2 tables "Trade". We have already existing Hibernate based DAO layer to fetch/store trades from/to DB. When we decide to partition the database, how can we control the trades to go in which of the two tables through hibernate. Basically I want , the trades need to be deleted by end of the day, to go in partitioned table and the trades I want to keep, in main table. Please suggest how can this be possible with Hibernate. We may add an additional column to identify the trades to be deleted but how can we ensure these trades should go to partitioned trade table using hibernate. I would appreciate if someone can suggest any better approach in case we are on wrong path.

  • Problem with checkboxes, sql select statements & php

    - by smokey20
    I am trying to display some rows from a database table based on choices submitted by the user. Here is my form code <form action="choice.php" method="POST" > <input type="checkbox" name="variable[]" value="Apple">Apple <input type="checkbox" name="variable[]" value="Banana">Banana <input type="checkbox" name="variable[]" value="Orange">Orange <input type="checkbox" name="variable[]" value="Melon">Melon <input type="checkbox" name="variable[]" value="Blackberry">Blackberry From what I understand I am placing the values of these into an array called variable. Two of my columns are called receipe name and ingredients(each field under ingredients can store a number of fruits). What I would like to do is, if a number of checkboxes are selected then the receipe name/s is displayed. Here is my php code. <?php // Make a MySQL Connection mysql_connect("localhost", "*****", "*****") or die(mysql_error()); mysql_select_db("****") or die(mysql_error()); $variable=$_POST['variable']; foreach ($variable as $variablename) { echo "$variablename is checked"; } $query = "SELECT receipename FROM fruit WHERE $variable like ingredients"; $row = mysql_fetch_assoc($result); foreach ($_POST['variabble'] as $ingredients) echo $row[$ingredients] . '<br/>'; ?> I am very new to php and just wish to display the data, I do not need to perform any actions on it. I have tried many select statements but I cannot get any results to display. My db connection is fine and it does print out what variables are checked. Many thanks in advance.

  • jquery draggable/droppable issue

    - by Scarface
    Hey guys I have a drag and drop function that does not fully work. What I want to do is be able to drag and drop a picture into a div and have that picture pop up in the div. I have a list of 2 pictures right now, so I have the following function echoed for each picture. Both pictures are draggable and droppable, but the first one is the only one that appears in the div, regardless of which picture gets dragged in. I am not sure what is wrong because the jquery function seems to be unique to each picture. If any one has any suggestions I would appreciate it greatly. while ($row = mysql_fetch_assoc($query)) { $image=htmlentities($row['image']); //image name $uniqid=uniqid(); //unique id for jquery functions $dirname = "usercontent/$user/images/$image"; echo "<img id=\"$uniqid\" src=\"$dirname\" width=\"75\" height=\"75\"/>"; echo "<script> $(function() { $(\"#$uniqid\").draggable({ scroll: true, scrollSensitivity: 10, scrollSpeed: 10, revert: true, helper: 'clone', cursorAt: { cursor: 'move', top: 27, left: 27 } }); $(\"#droppable2, #droppable-background , #droppable2-innerer\").droppable({ greedy: true, activeClass: 'ui-state-hover', hoverClass: 'ui-state-active', drop: function(event, ui) { $(this).addClass('ui-state-highlight').find('> p').html('Dropped!'); $('#droppable-background').css(\"background-image\",\"url($dirname)\"); } }); }); </script>"; }

  • Oracle Forms on-button-pressed trigger to solve three scenarios

    - by DBase486
    Hello, I'm writing a when-button-pressed trigger on a save button for an Oracle Forms 6i form, and it has to fulfill a couple of scenarios. Here's some background information: the fields we're primarily concerned with are: n_number, alert_id, end_date For all three scenarios we are comparing candidate records against the following records in the database (for the sake of argument, let's assume they're the only records in the database so far): alert_id|| n_number|| end_date ------------------------------------- 1|| 5|| _______ 2|| 6|| 10/25/2009 Scenario 1: The user enters a new record: alert_id 1 n_number 5 end_date NULL Objective: prevent the user from committing duplicate rows Scenario 2: The user enters a new record: alert_id 1 n_number 10 end_date NULL Objective: Notify the user that this alert_id already exists, but allow the user the ability to commit the row, if desired. Scenario 3: The user enters a new record: alert_id 2 n_number 6 end_date NULL Objective: Notify the user that this alert_id has occurred in the past (i.e. it has a not-null end_date), but allow the user to commit the row, if desired. I've written the code, which seems to comply with the first two scenarios, but prevents me from fulfilling the third. Issues: When I enter the third scenario case, I am prompted to commit the record, but when I attempt this, the "duplicate_stop" alert pops up, preventing me. Issues: I'm getting the following error: ORA-01843: not a valid month. While testing the code for the third scenario in Toad (hard-coding the values, etc) things seemed to be fine. Why would I encounter these problems at run-time? Help is very much appreciated. Thank you

  • JQuery Ajax Get passing parameters

    - by George
    Hi, I am working on my first MVC application and am running into a bit of a problem. I have a data table that when a row is clicked, I want to return the detail from that row. I have a function set up as: function rowClick(item) { $("#detailInfo").data("width.dialog", 800); $.ajax({ type: "GET", contentType: "application/json; charset=utf-8", url: "<%= Url.Action("GetDetails", "WarningRecognition")%>", data: "", dataType: "json", success: function(data) {//do some stuff...and show results} } The problem I am running into is the passing of the "item". I calls the Controller function that looks like this: public JsonResult GetDetails(string sDetail) { Debug.WriteLine(Request.QueryString["sDetail"]); Debug.WriteLine("sDetail: " + sDetail); var myDetailsDao = new WarnRecogDetailsDao(); return new JsonResult { Data = myDetailsDao.SelectDetailedInfo(Convert.ToInt32(sDetail)) }; } But it never shows anything as the the "sDetail". It does hit the function but nothing is passed to it. So, I have read where you pass the parameter via the data but I have tried every combination I can think of and it never shows up. Tried: data: {"item"} data: {sDetail[item]} data: {sDetail[" + item + "]} Any help is greatly appreciated. Thanks in advance. Geo...

  • Help! Getting an error copying the data from one column to the same column in a similar recordset..

    - by Mike D
    I have a routine which reads one recordset, and adds/updates rows in a similar recordset. The routine starts off by copying the columns to a new recordset: Here's the code for creating the new recordset.. For X = 1 To aRS.Fields.Count mRS.Fields.Append aRS.Fields(X - 1).Name, aRS.Fields(X - 1).Type, aRS.Fields(X - _ 1).DefinedSize, aRS.Fields(X - 1).Attributes Next X Pretty straight forward. Notice the copying of the name, Type, DefinedSize & Attributes... Further down in the code, (and there's nothing that modifies any of the columns between.. ) I'm copying the values of a row to a row in the new recordset as such: For C = 1 To aRS.Fields.Count mRS.Fields(C - 1) = aRS.Fields(C - 1) Next C When it gets to the last column which is a numeric, it craps with the "Mutliple-Step Operation Generated an error" message. I know that MS says this is an error generated by the provider, which in this case is ADO 2.8. There is no open connect to the DB at this point in time either. I'm pulling what little hair I have left over this one... (and I don't really care at this point that the column index is 'X' in one loop & 'C' in the other... I'll change it later when I get the real problem fixed...)

  • Can you stop a defered callback in jquery 1.5?

    - by chobo2
    Hi I am wondering say you have something like this // Assign handlers immediately after making the request, // and remember the jqxhr object for this request var jqxhr = $.ajax({ url: "example.php" }) .success(function(response) { alert("success"); }) // perform other work here ... // Set another success function for the request above jqxhr.success(function(response){ alert("second success"); }); So I am thinking this. I have a general function that I want to use on all my responses that would be passed into my success. This function basically does a check to see if the server validation found any errors. If it did they it formats it and displays a message. Now I am wondering if I could some how have the second success function to then do specific stuff. Like say One ajax request needs to add a row into a table. So this should be possible. I just do what I have above and in the second success I just add the row. Is it possible though that if the first success runs through and see that there are validation errors from the server that I can stop the second success from happening? Sort of If(first success finds errors) { // print out errors // don't continue onto next success } else { // go to next success } Edit I found that there is something call deferred.reject and this does stop it but I am wondering how can I specify to stop only the success one. Since my thinking is if there are other deffered ones like complete on it will the be rejected too?

  • MS SQL - Multi-Column substring matching

    - by hamlin11
    One of my clients is hooked on multi-column substring matching. I understand that Contains and FreeText search for words (and at least in the case of Contains, word prefixes). However, based upon my understanding of this MSDN book, neither of these nor their variants are capable of searching substrings. I have used LIKE rather extensively (Select * from A where A.B Like '%substr%') Sample table A: ID | Col1 | Col2 | Col3 | ------------------------------------- 1 | oklahoma | colorado | Utah | 2 | arkansas | colorado | oklahoma | 3 | florida | michigan | florida | ------------------------------------- The following code will give us row 1 and row 2: select * from A where Col1 like '%klah%' or Col2 like '%klah%' or Col3 like '%klah%' This is rather ugly, probably slow, and I just don't like it very much. Probably because the implementations that I'm dealing with have 10+ columns that need searched. The following may be a slight improvement as code readability goes, but as far as performance, we're still in the same ball park. select * from A where (Col1 + ' ' + Col2 + ' ' + Col3) like '%klah%' I have thought about simply adding insert, update, and delete triggers that simply add the concatenated version of the above columns into a separate table that shadows this table. Sample Shadow_Table: ID | searchtext | --------------------------------- 1 | oklahoma colorado Utah | 2 | arkansas colorado oklahoma | 3 | florida michigan florida | --------------------------------- This would allow us to perform the following query to search for '%klah%' select * from Shadow_Table where searchtext like '%klah%' I really don't like having to remember that this shadow table exists and that I'm supposed to use it when I am performing multi-column substring matching, but it probably yields pretty quick reads at the expense of write and storage space. My gut feeling tells me there there is an existing solution built into SQL Server 2008. However, I don't seem to be able to find anything other than research papers on the subject. Any help would be appreciated.

  • need help optimizing oracle query

    - by deming
    I need help in optimizing the following query. It is taking a long time to finish. It takes almost 213 seconds . because of some constraints, I can not add an index and have to live with existing ones. INSERT INTO temp_table_1 ( USER_ID, role_id, participant_code, status_id ) WITH A AS (SELECT USER_ID user_id,ROLE_ID, STATUS_ID,participant_code FROM USER_ROLE WHERE participant_code IS NOT NULL), --1 B AS (SELECT ROLE_ID FROM CMP_ROLE WHERE GROUP_ID = 3), C AS (SELECT USER_ID FROM USER) --2 SELECT USER_ID,ROLE_ID,PARTICIPANT_CODE,MAX(STATUS_ID) FROM A INNER JOIN B USING (ROLE_ID) INNER JOIN C USING (USER_ID) GROUP BY USER_ID,role_id,participant_code ; --1 = query when ran alone takes 100+ seconds --2 = query when ran alone takes 19 seconds DELETE temp_table_1 WHERE ROWID NOT IN ( SELECT a.ROWID FROM temp_table_1 a, USER_ROLE b WHERE a.status_id = b.status_id AND ( b.ACTIVE IN ( 1 ) OR ( b.ACTIVE IN ( 0,3 ) AND SYSDATE BETWEEN b.effective_from_date AND b.effective_to_date )) ); It seems like the person who wrote the query is trying to get everything into a temp table first and then deleting records from the temp table. whatever is left is the actual results. Can't it be done such a way that there is no need for the delete? We just get the results needed since that will save time?

  • Mysql query in drupal database - groupwise maximum with duplicate data

    - by nselikoff
    I'm working on a mysql query in a Drupal database that pulls together users and two different cck content types. I know people ask for help with groupwise maximum queries all the time... I've done my best but I need help. This is what I have so far: # the artists SELECT users.uid, users.name AS username, n1.title AS artist_name FROM users LEFT JOIN users_roles ur ON users.uid=ur.uid INNER JOIN role r ON ur.rid=r.rid AND r.name='artist' LEFT JOIN node n1 ON n1.uid = users.uid AND n1.type = 'submission' WHERE users.status = 1 ORDER BY users.name; This gives me data that looks like: uid username artist_name 1 foo Joe the Plumber 2 bar Jane Doe 3 baz The Tooth Fairy Also, I've got this query: # artwork SELECT n.nid, n.uid, a.field_order_value FROM node n LEFT JOIN content_type_artwork a ON n.nid = a.nid WHERE n.type = 'artwork' ORDER BY n.uid, a.field_order_value; Which gives me data like this: nid uid field_order_value 1 1 1 2 1 3 3 1 2 4 2 NULL 5 3 1 6 3 1 Additional relevant info: nid is the primary key for an Artwork every Artist has one or more Artworks valid data for field_order_value is NULL, 1, 2, 3, or 4 field_order_value is not necessarily unique per Artist - an Artist could have 4 Artworks all with field_order_value = 1. What I want is the row with the minimum field_order_value from my second query joined with the artist information from the first query. In cases where the field_order_value is not valuable information (either because the Artist has used duplicate values among their Artworks or left that field NULL), I would like the row with the minimum nid from the second query.

  • Defining default value in combobox in CakePHP

    - by Keyur
    <?php echo $form->create('admin_merchant_form', array('action' => '#')); echo $form->input('company_name', array('label' => 'Company Name')); echo $form->input('ac_owner', array('label' => 'Account Owner', 'options' => array('a','b','b'), 'default' => $merchant_select)); echo $form->end('Update'); ?> This is CakePHP code to generate a form with one combobox containing the values "a,b,c" and assigning the default value as $merchant_select which is numerical data. Now the problem is when I assign like 'default'=1 it returns 'b' in the combobox as default value but when writing 'default' = $merchant_select the combobox shows only the first value which is 'a'. The $merchant_select variable is assigned a numeric value equal to merchant's id which 1,2 or 3 when I select any row in the grid. And I also have JavaScript code which alerts with the merchant value when I select any row in the grid so the numeric data is definitely assigned to the $merchant_select variable.

  • iPhone app, navigationcontroller not functioning?

    - by dramaticlook
    I have 4 tabs in a tab bar. In one of the tabs i want to use a navigation, i.e. when i click an item from the list it should go to some details page about it. I have the list page where i have the navigation bar and the list of items. I can scroll them, but when I click any of them the selection animation happens, console logs the true row value, it even prints log instructions from constructor of the Details page but I can not see the Details page showing up. (btw Xcode 3.2.6 with iOS 4.3) - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *rowValue = [myStrings objectAtIndex:indexPath.row]; NSLog(rowValue); //[Utility setStr:rowValue]; [self.myTable deselectRowAtIndexPath:indexPath animated:TRUE]; //DETAILS PAGE HERE!!!! RestViewController * rest= [[RestViewController alloc] init]; rest.scoreLabel.text = rowValue; [self.navigationController pushViewController:rest animated:TRUE]; [rest release]; } Anybody having any idea? Thanks in advance!!!

  • 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?

  • li + float crashes IE6

    - by DMin
    I know. The dreaded ugly browser we don't want to support, but, it seems it couldn't be simpler to crash this thing. The URL The images gallery is a Joomla Plugin(Sigplus) and works fine with all other standard browsers. In IE it was not showing correctly, all the images were showing in one line vertically one below the other. But the browser would not hang or crash and the gallery worked as well. This is a Joomla plugin and I didn't want to mess with how it works, so, for IE I added a simple rule in the header : <!--[if lt IE 7]> <style> li { float:left; margin-right:5px; } </style> <![endif]--> This fixed the issue and the gallery shows up as it should. But, as you scroll down, as you reach the last row of images IE hangs and crashes. I tried deleting the last 5 images thinking it was something to do with the images themselves. But now it hangs on the current last row and crashes. Know what it could be?
