  • Django Template - Convert python list into a javascript object

    - by amcashcow
    I am working on a django / python website I have a page where I want to display a table of search results The list of results is passed in to the template as normal I also want to make this list of objects accessible to the javascript code My first solution was just create another view that returned json format. But each page load required calling the query twice. So then I tried only downloading the data using the json view and printing the table using javascript. but this is also not desirable as now the presentation layer is mixed into the javascript code. is there a way to create a javascript object from the python list as the page is rendered?

  • how to store data with many categories and many properties efficiently?

    - by Mickey Shine
    We have a large number of data in many categories with many properties, e.g. category 1: Book properties: BookID, BookName, BookType, BookAuthor, BookPrice category 2: Fruit properties: FruitID, FruitName, FruitShape, FruitColor, FruitPrice We have many categories like book and fruit. Obviously we can create many tables for them (MySQL e.g.), and each category a table. But this will have to create too many tables and we have to write many "adapters" to unify manipulating data. The difficulties are: 1) Every category has different properties and this results in a different data structure. 2) The properties of every categoriy may have to be changed at anytime. 3) Hard to manipulate data if each category a table (too many tables) How do you store such kind of data?

  • Incrementing through mysql PHP

    - by Rawdon
    I am looking at try to increment and decrement by three records through a table and present those records. Say if the id '4' is currently active. I want the to be display the ID's and category of 3.2.1 and 5.6.7 from an increment and decrement So far I have: $stmt = $db->query("SELECT id, category FROM test"); $stmt->execute(); while ($results = $stmt->fetch(PDO::FETCH_ASSOC)) { $current = $results['id']; $category = $results['category']; $next = array(array('slide_no' => $current, 'category' => $category)); } print_r($next); Now with this, I am getting back every row in the table. I'm now getting confused on how I could increment and decrement the records by 3 and make sure that the category will also increment correctly. Thank you very much.

  • I need a very simple PHP database front-end admin panel; a simple records editor for a specified tab

    - by Lansen Q
    Hi there, I am looking to add some dynamics to our corporate website. This is a secondary role so I'd rather not be spending a ton of time on it. At this point, all I need is a simple PHP script where a non-technical user can pull up and manage the records in a MySQL table. There's only one table of data to be managed; it's just that it will be accessed and updated quite frequently. I recall that Grails' default scaffolding feature has precisely this: list of entries with the ability to add, edit and delete, with no nonsense. What would be the best tool to use for this? I would rather not be writing it from scratch, as this will take me quite some time. It seems like the kind of thing that ought to exist somewhere. Thanks!

  • Left outer joins that don't return all the rows from T1

    - by Summer
    Left outer joins should return at least one row from the T1 table if it matches the conditions. But what if the left outer join performs a join successfully, then finds that another criterion is not satisfied? Is there a way to get the query to return a row with T1 values and T2 values set to NULL? Here's the specific query, in which I'm trying to return a list of candidates, and the user's support for those candidates IF such support exists. SELECT c.id, c.name, s.support FROM candidates c LEFT JOIN support s on s.candidate_id = c.id WHERE c.office_id = 5059 AND c.election_id = 92 AND (s.user_id = 2 OR s.user_id IS NULL) --This line seems like the problem ORDER BY c.last_name, c.name The query joins the candidates and support table, but finds that it's a different user who supported this candidate (user_id=3, say). Then the candidate disappears entirely from the result set.

  • Automatic form generation software

    - by Jonathan
    Hi! I'm using winforms. I spend a lot of time drawing forms (maybe not a lot, but it is a boring task). To sum up... I want to develop a simple aplication that connect to a sql server database, let the user to select a table, and put the controls in a form for me (generate the designer code), based on the tipe of each column. Then my app will name each control like the column of the table, set the maxlengh property (if the type is varchar), and create a label with the same text near the control. If the column is a FK, then the app will draw a combobox and so on. I saw that Telerik Open ORM make something like this, but I only need a simple app for the IU Generation. If the same day I finish my little application I discover a tool that make the same... I will feel myself stupid :D Are there any tool out there that do this work for me? Thanks

  • (Symfony) How can i change the templating of a form in sfDoctrineGuardPlugin ?

    - by ruic
    How can i change the templating of a form in sfDoctrineGuardPlugin? That is, I need to change the html (class, id) of the input elements (username, password) of a login form provided by sfDoctrineGuardPlugin. I've changed apps/app_name/modules/sfGuardAuth/templates/singinSuccess.php, but it then just echoes $form (I need to change contents of that part - $form): <form action="<?php echo url_for('@sf_guard_signin') ?>" method="post"> <table> <?php echo $form ?> </table> <input type="submit" class="go_button" value="ir" /> <a href="<?php echo url_for('@sf_guard_password') ?>"><?php echo __('Forgot your password?') ?></a> </form> (It really should be something like changing a _form.php = I cant find this, though :S) Thank you all for any answers provided =)

  • Question about inserting/updating rows with SQL Server (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • Is there a way to find TOP X records with grouped data?

    - by Chris Simmons
    I'm working with a Sybase 12.5 server and I have a table defined as such: CREATE TABLE SomeTable( [GroupID] [int] NOT NULL, [DateStamp] [datetime] NOT NULL, [SomeName] varchar(100), PRIMARY KEY CLUSTERED (GroupID,DateStamp) ) I want to be able to list, per [GroupID], only the latest X records by [DateStamp]. The kicker is X 1, so plain old MAX() won't cut it. I'm assuming there's a wonderfully nasty way to do this with cursors and what-not, but I'm wondering if there is a simpler way without that stuff. I know I'm missing something blatantly obvious and I'm gonna kick myself for not getting it, but .... I'm not getting it. Please help. Is there a way to find TOP X records, but with grouped data?

  • Rendering field data as a link in Ruby on Rails...

    - by bgadoci
    Ok, I think this is probably an easy question but for the life of my I can't figure it out. I have created a table called ugtags and in that table I have two columns (beyond the basics), 'name' and 'link'. I am trying to allow a user to add a link to a page. Ideally they would enter the link title (name) and the url (link) and in the view it would display the title as a link to the url that was entered in the link column. I there a way to do it by simply affecting the <%= link_to h(ugtag.name) %> code?

  • Any idea why this query always returns duplicate items?

    - by Kardo
    I want to get all Images not used by current ItemID. The this subquery but it also always returns duplicate Images: EDITED select Images.ImageID, Images.ItemStatus, Images.UserName, Images.Url, Image_Item.ItemID, Image_Item.ItemID from Images left join (select ImageID, ItemID, MAX(DateCreated) x from Image_Item where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e' group by ImageID, ItemID having count(*) = 1) image_item on Images.imageid = image_item.imageid where ItemID is not null I guess the problem is with the subquery which I can't avoid duplicate rows: select ImageID, ItemID, MAX(DateCreated) x from Image_Item where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e' group by ImageID, ItemID having count(*) = 1 Result: F2EECBDC-963D-42A7-90B1-4F82F89A64C7 0578AC61-3C32-4A1D-812C-60A09A661E71 F2EECBDC-963D-42A7-90B1-4F82F89A64C7 9A4EC913-5AD6-4F9E-AF6D-CF4455D81C10 42BC8B1A-7430-4915-9CDA-C907CBC76D6A CB298EB9-A105-4797-985E-A370013B684F 16371C34-B861-477C-9A7C-DEB27C8F333D 44E6349B-7EBF-4C7E-B3B0-1C6E2F19992C Table: Images ImageID uniqueidentifier UserName nvarchar(100) DateCreated smalldatetime Url nvarchar(250) ItemStatus char(1) Table: Image_Item ImageID uniqueidentifier ItemID uniqueidentifier UserName nvarchar(100) ItemStatus char(1) DateCreated smalldatetime Any kind help is highly appreciated.

  • Creating new Entities from Stored Procedure

    - by SK
    I have a stored procedure that retrieves existing rows from a table and also creates includes new rows that match the table definition and mapped entity (.net 3.5 entity framework). These new rows are not written to the database in the stored procedure. The stored procedure executes, but the new rows that were created will not load the navigation properties sucessfully i.e. the rows that do not actually exist in the database. e.g. database rows: key, data, FK 1, xxx, a 2, xxx, b returned rows from stored procedure: key, data, FK 1, xxx, a 2, xxx, b 3, yyy, a 4, yyy, b The entity will load FK entities a and b for rows 1 and 2, but for rows 3 and 4 the FK entity is null. Do I somehow need to add the new rows to the data context? or turn off tracking?

  • Sorting and displaying a custom QVariant type.

    - by Kranar
    Hello, I have a custom type I'd like to use with QVariant but I don't know how to get the QVariant to display in a table or have it sort in a QSortFilterProxyModel. I register the type with Q_DECLARE_METATYPE and wrote streaming operators registered via qRegisterMetaTypeStreamOperators but for whatever reason when I use the type with a table model, it doesn't display anything and it doesn't sort. I should specify that this custom type can not be modified. It has a copy and default constructor, but I can not go in and modify the source code to get it to work with QVariant. Is there a way of non-intrusively getting the behaviour I'd like?

  • how to select distinct rows for a column

    - by Satoru.Logic
    Hi, all. I have a table x that's like the one bellow: id | name | observed_value | 1 | a | 100 | 2 | b | 200 | 3 | b | 300 | 4 | a | 150 | 5 | c | 300 | I want to make a query so that in the result set I have exactly one record for one name: (1, a, 100) (2, b, 200) (5, c, 300) If there are multiple records corresponding to a name, say 'a' in the table above, I just pick up one of them. In my current implementation, I make a query like this: select x.* from x , (select distinct name, min(observed_value) as minimum_val from x group by name) x1 where x.name = x1.name and x.observed_value = x1.observed_value; But I think there may be some better way around, please tell me if you know, thanks in advance.
