  • How to send complete POST to Model in Code Igniter

    - by Constant M
    Hi there, What would be the best way to send a complete post to a model in Code Igniter? Methods I know are as follow: Name form elements as array, eg. <input type="text" name="contact[name]"> <input type="text" name="contact[surname]"> and then use: $this->Model_name->add_contact($this->input->post('contact')); The other would be to add each element to an array and then send it to the model as such: <input type="text" name="name"> <input type="text" name="surname"> and $contact_array = array('name' => $this->input->post('name'), 'surname' => $this->input->post('surname')); $this->Model_name->add_contact($this->input->post('contact')); Which one of these would be best practice, and is there a way to directly send a whole POST to a model (or a whole form maybe?)

  • Facebook Black Screen when in IFrame

    - by Rico
    I have Facebook in an Iframe for the convenience of my clients. But all of a sudden it doesn't work.. It simply covers itself with a black screen. Is there a work around? Something I can do. Maybe even have someone code to their API to get all the functionality back. Is there a sollution already out there?? <html> <body> <iframe src="http://www.facebook.com/" width=800 height=600 /> </body> </html>

  • How do you handle multiple (overlapping) projects in trac?

    - by Oliver Giesen
    We are using trac and are really satisfied with it. However, out of the box, trac is best suited for single-project environments only. I'd be interested to hear about the various approaches people take to make it work with multiple projects nevertheless and their experiences with them. Are there any plugins to recommend? Any patches, tweaks or whatnots? Are you maybe even using an entirely different bug-tracking system that offers all of trac's functionality plus multi-project support? We recently started managing a second project ourselves which generally works okay but also has some drawbacks, especially where the two projects overlap because of common library code we wrote that is used in both projects. How do you handle this? (I'll attach our own current approach as an answer to this post.)

  • How should I migrate DDL changes from one environment to the next?

    - by Rl
    I make DDL changes using SQL Developer's GUI. Problem is, I need to apply those same changes to the test environment. I'm wondering how others handle this issue. Currently I'm having to manually write ALTER statements to bring the test environment into alignment with the development environment, but this is prone to error (doing the same thing twice). In cases where there's no important data in the test environment I usually just blow everything away, export the DDL scripts from dev and run them from scratch in test. I know there are triggers that can store each DDL change, but this is a heavily shared environment and I would like to avoid that if possible. Maybe I should just write the DDL stuff manually rather than using the GUI?

  • Adding more OR searches with CONTAINS Brings Query to Crawl

    - by scolja
    I have a simple query that relies on two full-text indexed tables, but it runs extremely slow when I have the CONTAINS combined with any additional OR search. As seen in the execution plan, the two full text searches crush the performance. If I query with just 1 of the CONTAINS, or neither, the query is sub-second, but the moment you add OR into the mix the query becomes ill-fated. The two tables are nothing special, they're not overly wide (42 cols in one, 21 in the other; maybe 10 cols are FT indexed in each) or even contain very many records (36k recs in the biggest of the two). I was able to solve the performance by splitting the two CONTAINS searches into their own SELECT queries and then UNION the three together. Is this UNION workaround my only hope? Thanks. SELECT a.CollectionID FROM collections a INNER JOIN determinations b ON a.CollectionID = b.CollectionID WHERE a.CollrTeam_Text LIKE '%fa%' OR CONTAINS(a.*, '"*fa*"') OR CONTAINS(b.*, '"*fa*"') Execution Plan (guess I need more reputation before I can post the image):

  • strange characters at beginning of file

    - by luca
    there are strange characters at the beginning of a file I'm editing (using textmate..) I don't know when they appeared, they're invisible in textmate but my script that reads the file goes crazy.. this is the first few chars in the file (as seen with od command): 0000000 177377 000120 000105 000117 000120 000114 000105 000072 the first 2 shouldn't be there I think.. maybe they were caused by some strange dropbox sync? Or something else.. but they tend to reappear (I don't yet know when..) My question: what is that 177377 and a simple way to remove it in my ruby script? thanks

  • Is there a faster way to draw text?

    - by mystify
    Shark complains about a big performance hit with this line, which takes like 80% of CPU time. I have a counter that is updated very frequently and performance seriously sucks. It's an custom UILabel subclass with -drawRect: implemented. Every time the counter value changes, this is used to draw the new text: [self.text drawInRect:textRect withFont:correctedFont lineBreakMode:self.lineBreakMode alignment:self.textAlignment]; When I comment this line out, performance rocks. Its smooth and fast. So Shark isn't wrong about this. But what could I do to improve this? Maybe go a level deeper? Does that make any sense? Probably drawing text is really so incredible heavy...?

  • How to generilize view?

    - by MexicanHacker
    Hey guys, I'm in the process of designing a set of views that use the same model in my app, the difference is that some views will differ in Read Only and Modifiable fields. So for example for view A I want to be able to modify A.One but no A.Two properties and for view B I want to have B.One and B.Two as modifiable fields. I was thinking in having a map that will hold this information and iterate both the modifiable and non-modifiable lists in a generic view, but I was thinking that maybe I can get feedback from you guys. What do you think?

  • How do I get characters common to two vectors in C++?

    - by Sam Phelps
    I am trying to compare two vector objects, and return a single vector containing all the chars which appear in both vectors. How would I go about this without writing some horribly complex manual method which compares every char in the first vector to every char in the second vector and using an if to add it to a third vector (which would be returned) if they match. Maybe my lack of real experience with vectors is making me imagine this will be harder than it really is, but I suspect there is some simplier way which I have been unable to find through searching.

  • Optional URL fragment in Codeigniter?

    - by DA
    This is maybe a simple syntax question or possibly a best-practices question in terms of codeigniter. I should start by saying I'm not a PHP or Codeigniter person so trying to get up to speed on helping on a project. I've found the CI documentation fairly good. The one question I can't find an answer to is how to make part of a URL optional. An example the CI documentation uses is this: example.com/index.php/products/shoes/sandals/123 and then the function used to parse the URI: function shoes($sandals, $id) For my example, I'd like to be able to modify the URL as such: example.com/index.php/products/shoes/all So, if no ID is passed, it's just ignored. Can that be done? Should that be done? A second question unrelated to my problem but pertaining to the example above, why would the variable $sandals be used as in the example, the value is 'sandals'? Shouldn't that variable be something like $shoetype?

  • C# app that uses Excel Interop, easy switch between 2003 2007?

    - by user320781
    I have an app written that just does really basic I/O on a spreadsheet. Read in a bunch of cells, do some sorting, and dump the output back into another spreadsheet. Works great on my machine. I have Office 2003 installed. When it runs on someone elses machine with 2007, it bombs, presumably due to the different versions of the Interop assemblies. I was hoping someone knew a way to dynamically change which/where the assembly is loaded from depending on the office version (getting the office version is easy from the registry). Sifting thru the rest of the internet, i didnt see anything to indicate that was possible :( . I tried installing the 2007 PIAs, but when i try to add a reference, they dont show up and i have no idea where to browse for them (they arent in the c:\windows\assemblies\; maybe the install didnt work). Am I going to have to get a machine with 2007 installed to build on every time i need to make updates?

  • Annotations: methods vs variables

    - by Zenzen
    I was always sure (don't know why) that it's better to add annotations to variables, but while browsing the Hibernate doc http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-hibspec-collection I noticed they tend to annotate the methods. So should I put my annotations before methods, like this: @Entity public class Flight implements Serializable { private long id; @Id @GeneratedValue public long getId() { return id; } public void setId(long id) { this.id = id; } } Or is it better to do it like this: @Entity public class Flight implements Serializable { @Id @GeneratedValue private long id; public long getId() { return id; } public void setId(long id) { this.id = id; } } Or maybe there's no difference?

  • How can you pass GET values to another url in php? GET value forwarding

    - by gobackpacking
    Ok, so I'm using Jquery's AJAX function and it's having trouble passing a URL with a http address. So I'm hoping to "get" the GET values and send them to another URL — so: a local php file begin passed GET values, which in turn forwards the GET values to another url. Maybe curl is the answer? I don't know. It's got to be a very short answer I know. pseudo code: //retrieve the GET values $var retrieve [GET] //passing it to another url send get values to url ($var, url_address)

  • is it some bug in firefox or jquery or i doing something wrong?

    - by llamerr
    I want to change hidden input value on div click, so i do following: $('#gallery').click(function(){ if ($('input[name=isgallery]').attr('value') == '0') { $('input[name=isgallery]').attr('value', '1') } else { $('input[name=isgallery]').attr('value', '0') } $('#filterform').attr('action',$('#filterform').attr('act')); alert('ok'); $('#filterform').submit(); } ); when it equals 0 i change it to 1 and otherwise but it did not work and following code works: $('#gallery').click(function(){ if ($('input[name=isgallery]').attr('value') == '0') { $('input[name=isgallery]').attr('value', '0') } else { $('input[name=isgallery]').attr('value', '1') } $('#filterform').attr('action',$('#filterform').attr('act')); alert('ok'); $('#filterform').submit(); } ); and also, when i delete the function at all it still works and form submits maybe i have one more handler for this div, but i can't find one you can check it on http://www.4block.org/en/museum/posters and click "gallery view" on top-right

  • Build config file into executable?

    - by REM
    I am currently working on a little graphics demo (using DirectX) which is primarily based around an HLSL shader I am working on. Using the D3DX10CreateEffectFromFile I am loading (and compiling the shader) at runtime as I find it easier for tweaking. However, once I am done I'd like to do some combination of the following: Pre-compile the shader so the demo starts up faster for the user Bury (compile into the executable) the compiled shader (or maybe just the source if necessary) Primarily, I want to do this because I want the demo to just be one file that can be very easily copied around. One thing I could easily do is just put the source text right into a cpp but that would be very tedious I needed to update it later. Is it possible to do something like this (using Visual Studio, DirectX, HLSL)?

  • Best Practice for Exporting an App's Data to XML via PHP/MySQL?

    - by Alex Cook
    I have an a business app and I want to give my users the ability to export their data at anytime. I'm aware that I can write an XML file semi-manually by doing something like this: http://www.kirupa.com/web/mysql_xml_php.htm But, I thought I'd ask if this is the best practice? Or is there some framework I can use to do this more easily/quickly? Maybe there isn't - it won't be too hard to do it the above way. Also, less importantly - XML is the best format to export to, right? Thanks in advance.

  • LINQ parent child relation

    - by Shane Km
    I'm working on the BLOG functionality in MVC. I need to be able to create 'blog comments'. So each comment may have a parent comment etc. Given table "Comments": CommentId - int - identity autoincrement PostId - int ParentId - int Comment - string Is there a way to get a list of comments for a given article ordered by CreateDate and ParentId? Or maybe there is a better table design you may suggest. What is the best design when inserting Post comments like this? I'm using Entity framework. thanks

  • What do you name the "other" kind of view-model in an MVVM project?

    - by DanM
    With MVVM, I think of a view-model as a class that provides all the data and commands that a view needs to bind to. But what happens when I have a database entity object, say a Customer, and I want to build a class that shapes or flattens the Customer class for use in a data grid. For example, maybe this special Customer object would have a property TotalOrders, which is actually calculated using a join with a collection of Order entities. My question is, what do I call this special Customer class? In other situations, I'd be tempted to call it a CustomerViewModel, but I feel like "overloading" the notion of a view-model like this would be confusing in an MVVM project. What would you suggest?

  • Android - Fill Layout with Buttons

    - by GuyNoir
    Just a quick question about how you would go about implementing this. I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added. For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons. Any suggestions? It can't scroll either, it just has to dynamically fill the layout with buttons. Thanks.

  • What's an elegant solution to get the property values from two classes (that have the same property

    - by SlipToFall
    Essentially I have to deal with a poorly implemented web service. They have two classes that don't derive from a parent class, but have the same properties (Ughh...). So it looks like this in my web service proxy class file: public partial class Product1 { public int Quantity; public int Price; } public partial class Product2 { public int Quantity; public int Price; } So what's the best way to grab the values from known properties without duplicating the code and casting to their respective classes? I know I probably could use reflection, but that can get ugly. If there is an easier less crazier way to do it (maybe in the new c# features?) please let me know.

  • In your opinion what web technology would be best suited for building dropdown menus?

    - by LondonGuy
    What I need is a slide menu that is activated by one click. The menu then appears and doesn't disappear until user clicks any where else on the current page. I don't require any effects but need something reliable that I can style with ease, put a thumbnail of a photo inside change dimensions, add mouse over effects etc. I've done a several searches on google and quite a lot of options are coming up and I'm not too sure which would be best for me. I've seen some people suggestion html + css3 and others suggest jquery. Does any of these options have a benefit over the other? I would appreciate your opinions and maybe some links thanks.

  • Help regarding no sql databases like hadoop, hbase etc

    - by user560370
    I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

  • Unlock Key Component

    - by mob1lejunkie
    Hi, I have almost completed my Android application so am considering ways of distributing the application. I have seen some applications on Market have free limited/locked version and separate Unlock Key/License Key which unlocks extra functionality. How is this done? Has anyone here done this? If so, how well does it work? I am thinking maybe this is better then having two versions of the same application (i.e Lite and Pro). Thanks.

  • Is it possible to prevent iPhone/iPad orientation changing in the browser?

    - by BoomShaka
    I've seen similar questions on this issue, but they are related to native apps. I build web apps for the iPhone/iPad that run in the browser (Safari). I was wondering if there is a way to prevent orientation change in the browser, perhaps via some meta tag. I know of the viewport meta tag which allows you to specify scale and zooming capabilities, so figured maybe there is something similar for orientation. I doubt it is possible, but I thought I'd just pop a question on here to see.
