• Django: How/Where to store a value for a session without unnecessary DB hits

  - by GerardJP

  Hi all, I have an extended userprofile with AUTH_PROFILE_MODULE (ref: http://tinyurl.com/yhracqq) I would like to set a user.is_guru() method similar to user.is_active(). This would results for al views (or rather templates) to e.g. disable/enable certain user messages, displaying of widgets, etc. The boolean is stored in the extended user profile model, but I want to avoid hitting the DB for every view. So the questions is .. Do I use a context_processor, a template tag, session_dict or what have you to, possible cached, store this info for the duration of the users visit. Note: I dont have performance issues, so it's definitely filed under premature optimization. I just want to avoid generating extra work in the future :). Any pointers are very welcome. Thanx and greetz! Gerard.

• Users adding views

  - by adamprocter

  I have created a main page (myAppViewController) and a add page rect button I have also created a page template (TemplateAViewController) all set up in Interface builder. I would like users to be able to add as many templates themselves and then page through them. I am not sure where to start. I can create views programmatic like so -(IBAction)createnewpage : (id) sender { myAppViewController *viewcontroller = [[myAppViewController alloc] initWithNibName:@"TemplateAViewController" bundle:[NSBundle mainBundle]]; [[self view] addSubview:viewcontroller.view]; } I then want to be able to navigate through these views- I guess I need to create a navigation controller to do this ?

• need to extract certain values from attribute and place them in variables

  - by user357034

  In the following markup on a page I want to extract out the following and put them in seperate variables. 1- In the onclick attribute get the value after the "ProductID" and put it in its own variable. "ProductID" So in this case it would be 318 2- In the onclick attribute get the value after the "Orig_price" and put it in a variable, "Orig_Price" So in this case it would be 22.95 3- In the onclick attribute get the value after the "width" and put it in a variable, "width" So in this case it would be 330 4- In the onclick attribute get the value after the "height" and put it in a variable, "height" So in this case it would be 300 <a href="javascript:void(0);" onclick="window.open('/BulkDiscounts.asp?ProductID=318&ProductCode=' + escape('LB30X40ES') + '&Orig_Price=22.95', 'Discounts', 'scrollbars,status,resizable,width=330,height=300');"><img src="/v/vspfiles/templates/100/images/buttons/btn_quantitydiscounts.gif" border="0" align="absmiddle"></a>

• When are C++ macros beneficial?

  - by Motti

  The C preprocessor is justifiably feared and shunned by the C++ community. In-lined functions, consts and templates are usually a safer and superior alternative to a #define. The following macro: #define SUCCEEDED(hr) ((HRESULT)(hr) >= 0) is in no way superior to the type safe: inline bool succeeded(int hr) { return hr >= 0; } But macros do have their place, please list the uses you find for macros that you can't do without the preprocessor. Please put each use-cases in a seperate answer so it can be voted up and if you know of how to achieve one of the answers without the preprosessor point out how in that answer's comments.

• Prevent the groupfield from repeating every three rows

  - by Aaron

  I have a web app and I need to integrate some JasperReports in this app. So I downloaded iReport and I used the templates. I choose the LeafGreen template, but I have a problem. When I have more than 4 elemets in my list, my headers gets repeated every 4 elements (see the image:) - I don't want this; once is enough. The problem: http://i39.tinypic.com/9kcp6p.jpg This is the template: http://i44.tinypic.com/2ags1w1.jpg What I'm doing wrong?

• Is vbscripting that difficult?

  - by eric young

  I need to write some vbscripts in my new project. I was told by other people that vbscripting is easy, but seems to me, it is not. For example, in the following example (provided by microsoft), these functions: CreateObject, CreateShortcut, as well as these property names: TargetPath, WindowStyle, Hotkey, etc, are used, but I just cannot find the corresponding API documentation about how to use them. In other words, how do you know you need to call these functions in your vbscripts? Visual Studio 2008/2010 do not have templates for vbscript either. Could anybody tell me what I am missing, and what the best way is to do vbscripting? set WshShell = WScript.CreateObject("WScript.Shell") strDesktop = WshShell.SpecialFolders("Desktop") set oShellLink = WshShell.CreateShortcut(strDesktop _ & "\MyExcel.lnk") oShellLink.TargetPath = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE" oShellLink.WindowStyle = 1 oShellLink.Hotkey = "CTRL+SHIFT+F" oShellLink.IconLocation = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE, 0" oShellLink.Description = "My Excel Shortcut" oShellLink.WorkingDirectory = strDesktop oShellLink.Save

• jQuery selector after dynamically created element

  - by Bryan Williams

  I am trying to get an dynamically created element using a jQuery selector but it is returning an empty array. The first thing I am doing is grabbing an empty div: var packDiv = document.getElementById('templates'); packDiv.innerHTML = ""; then adding items to it in a loop: packDiv.innerHTML = packDiv.innerHTML + "<img id='" + thumbName + "' src='thumbs/" + thumbName + "'/>"; after the loop finishes I try to select an item using: console.log($("#"+thumbName)); and it returns the empty array. All the things I search on show to use .on but all the examples show that is to set event handlers. My question is how do I format a selector for dynamically created elements?

• Help need for openfast implementation

  - by ganuke

  Our stock exchange going to implement FAST messaging in their system in order to reduced the bandwidth usage. We have already implement the FIX based application to trade with Stock exchange. In future we need implement FIX FAST in our application to communicate with them. I found that OPEN FAST is FAST based library. But I do not have any idea how to start with it. I went through OpenFast web site but could not find much support on how to use templates and dictionaries. Can some one guide me or provide some resources to start with? Thanks in advance.

• Custom Output => List of Errors interpretation in VS2008 IDE.

  - by Hamish Grubijan

  Hello, I have a "database solution" project in VS2008 - it generates SQL for more than one DB vendor from some sort of templates. In order to save time, I also have a tool in VS2008 configured (a Python script), which can compile an individual stored procedure. Now, with the Python script I have the freedom of processing the output and have it take on whatever form I want. I am toying with an idea of having these errors and warnings somehow recognized and populating the click-able Error / Warning list. This is what a typical Oracle error looks like: LINE/COL ERROR -------- ----------------------------------------------------------------- 324/5 PL/SQL: Statement ignored 324/82 PLS-00363: expression 'VSOURCE_SYSTEM_ID' cannot be used as an assignment target Warning: Procedure created with compilation errors. PROCEDURE: ADD_PROPOSED error on creation Errors for PROCEDURE ADD_PROPOSED: LINE/COL ERROR This might be a long shot, but it is worthwhile for me. I do this stuff a lot. Thank you!

• C++ Variable declarable in function body, but not class member?

  - by anon

  I want to create a C++ class with the following type: It can be declared inside of a function. It can be declared inside of a member function. It can not be declared as a class member. The use of this: think "Root" objects for a GC. Is this possible in C++? In particular, I'm using g++. Willing to switch to clang. Either templates or macro solution fine. Thanks!

• Does a Perl module know where it is installed?

  - by CoffeeMonster

  Hi Perl programmers, I have started creating a Perl package that contains a default email template. The MANIFEST looks something like: SendMyEmail.pm SendMyEmail/defualt_email.tt Currently I know where the module (and the template) are - but does the module itself know where on disk it is? So could the module find the default template without my help? # This is what I would like to do. package SendMyEmail; sub new { my ($self, $template) = @_; $template ||= $dir_of_SendMyEmail .'/SendMyEmail/default_email.tt'; # ?? } Is there a better way of including a templates text, or a better place to put the template? Any references to CPAN modules that do something similar would be welcome. Thanks in advance.

• Creating a db driven primary navigation in django?

  - by Fedor

  I find that it's pretty common most people hardcode the navigation into their templates, but I'm dealing with a pretty dynamic news site which might be better off if the primary nav was db driven. So I was thinking of having a Navigation model where each row would be a link. link_id INT primary key link_name varchar(255) url varchar(255) order INT active boolean If anyone's done something similar in the past, would you say this sort of schema is good enough? I also wanted for there to be an optional dropdown in the admin near the url field so that a user could choose a Category model's slug since category links would be common, but I'm not quite sure how that would be possible.

• Appropriate use of DL and DD?

  - by Ian

  I had some site templates designed for me recently. I got the final HTML code, which validates, but the structure of the document is laid out using DL-DD pairs: <dl> <dd class="some-class"> Some text. </dd> </dl> I'm not especially familiar with those tags as I've never used them much, but they don't seem intended for document structure. Am I right? Why would a designer do this?

• T4 Template Interception

  - by JeffN825

  I'm wondering if anyone out there knows of any T4 template based method interception systems? We are beginning to write mobile applications (currently with MonoTouch for IOS). We have a very nice core set of DI/IoC functionality and I'd like to leverage this in development for the new platform. Since runtime code generation Reflection.Emit is not supported, I'm hoping to use T4 templates to implement the dynamic interception functionality (+ TinyIoC as a container for resolution). We are currently using Castle Windsor (and intend to continue doing so for our SL and full .NET development), but all of the Windsor specific ties are completely encapsulated, so given a suitable T4 solution, it shouldn't be hard to implement an adapter that uses a T4 based implementation instead of Windsor.

• One account, multiple users, multiple shopping cart in a web application

  - by lemotdit

  I received a somewhat unusual request (imo) for a transactional web site. I have to implement the possibility of having multiple shopping cart for the same user. Those really are shopping carts, not order templates. I.E: A store with several departments ordering under the same account, but with a different person placing orders for a specific department only. Having more than one user per account is not an option since it would involve 'too much' management from the stores owner and the admins. Anyone had to deal with this before? The option so far is to have names for shopping cart, and a dropdown list or something alike after login to choose the cart with some kind of 'busy flag' to lock the cart if it's in use in another session.

• Making Django ignore string literals

  - by James

  UPDATE: It turns out this is a deeper question than I thought at first glance - the issue is that python is replacing the string literals before they ever get to django. I will do more investigating and update this if I find a solution. I'm using django to work with LaTeX templates for report generation, and am running into a lot of problems with the way Django replaces parts of strings. Specficially, I've run into two problems where I try to insert a variable containing latex code. The first was that it would replace HTML characters, such as the less than symbol, with their HTML codes, which are of course gibberish to a LaTeX interpreter. I fixed this by setting the context to never autoescape, like so: c = Context(inputs) c.autoescape = False However, I still have my second issue, which is that Django replaces string literals with their corresponding characers, so a double backslash becomes \, and \b becomes a backspace. How can I force Django to leave these characters in place, so inputs['variable'] = '{\bf this is code} \\' won't get mangled when I use {{variable}} to reference it in the django template?

• Accessing global variables within functions in PHP

  - by st3

  There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

• Why is new showat attribute required when using code generation?

  - by Patrick Karcher

  When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

• Reporting system for organization. Architecture advise required

  - by Andrew Florko

  We have several legacy & 3'd-party systems in organization that use several RDBMS vendors (& more specific data storages). Cross-system data reporting (as well as extra-reports that are not implemented in 3'd-party systems) is required with charts and population of templates (winword, excel). Reporting system is visioned as intranet web-site with custom user access to reports. We expect ~50 reports per day. Would you suggest to use BizTalk or any other integration software if commercial-department doesn't plan to buy anything expensive. Would you suggest to create centralized data storage for reporting that is populated regularly or rely on on-demand services that providers always up-to-request data. Thank you in advance!

• Django - Check users messages every request

  - by Hanpan

  Hi, I want to check if a user has any new messages each time they load the page. Up until now, I have been doing this inside of my views but it's getting fairly hard to maintain since I have a fair number of views now. I assume this is the kind of thing middleware is good for, a check that will happen every single page load. What I need it to do is so: Check if the user is logged in If they are, check if they have any messages Store the result so I can reference the information in my templates Has anyone ever had to write any middleware like this? I've never used middleware before so any help would be greatly appreciated.

• Have to put files in static_dir but need to read them afterwards

  - by SanjamX

  I just started using google app engine. In order to use templates, I'm using jinja2. I want to add images dynamically after I set the width and height of the img tag. I used PIL in order to read the image size and put the one I want. However when I open the image with PIL, I need it not to be in a static_dir and to put the image in the img tag, I need it to be in the static_dir. As a testing solution I've copied the folder to see if I get results and I did. But as you can see having each image saved twice is kind of bad.

• Membership systems for MVC4 that support RavenDB

  - by brad oyler

  I create a lot of quick "proof of concept" MVC apps and I actually found the SimpleMembership provider that shipped with the MVC4 templates to be very handy since it gets me up and running with user registration & OAuth in a matter of minutes. But...I've started to use RavenDb (on RavenHQ for a lot for my projects). So, I starting trying to implement my own "custom membership provider" based on the ExtendedMembershipProvider and while doing that I realized that didn't make much sense. I later stumbled upon 2 interesting projects that try to solve this exact problem: WorldDomination.Web.Auth: https://github.com/PureKrome/WorldDomination.Web.Authentication MemFlex: https://github.com/OdeToCode/Memflex Both are pretty interesting recent efforts and was wondering if these are the only ones being built right now. I'm essentially looking for nuget pkg that I can drop into a MVC4 app, connect to my RavenDb and be done. I'm willing to build this thing but don't want to duplicate any efforts that are already in motion. Thx!

• Apache Rewrite Excluding Assets Directory

  - by Midiane

  Hi all I'm writing a mini-MVC application. App architecture: actions/ templates/ site/ app/ styles/ images/ scripts/ So far, I've got a controller working properly, taking in all requests. However, javascript files are not being rendered properly in the browser; I'm getting a 404 Not Found when I try to load the file in the browser. Here is my current Directory config in a vhost file: DirectoryIndex index.php RewriteEngine On RewriteBase /apps/ecatalogue RewriteRule ^scripts/(.*) - [NC,L] <--- Rule not working RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [NC,L,QSA] I can confirm everything else works; I just need apache to ignore anything in scripts so the file can be loaded normally without being processed by the controller. Your help is appreciated.
