  • form_for [@parent,@son],:remote=>true not asking for JS

    - by Cibernox
    Hi. I have a plain old form. That form is used to create new objects of a nested model. #restaurant.rb has_many :courses #courses.rb belongs_to :restaurant #routes.rb resources :restaurants do resources :courses end In my views(in haml), i have that code: %li.course{'data-random'=>random} = form_for([restaurant,course], :remote=>true) do |f| .name= f.text_field :name, :placeholder=>'Name here' .cat= f.hidden_field :category .price= f.text_field :price,:placeholder=>'Price here' .save = hidden_field_tag :random,random = f.submit "Save" I espected that form to be answered by action create of courses_controller with JS (create.js.erb), but it is submited like a normal form, and is answered with html. What am I doing wrong? This problem is similar to this but the only answer don't make sense to me. Thanks Inside

  • Non-volatile cache RAID controllers: what kind of protection is there against NVCACHE failure?

    - by astrostl
    The battery back-up (BBU) model: admin enables write-back cache with BBU writes are cached to the RAID controller's RAM (major performance benefit) the battery saves uncommitted and cached data in the event of a power loss (reliability) If I lose power and come back within a day or so, my data should be both complete and uncorrupted. The downside to this is that, if the battery is dead or low, OR EVEN IF IT IS IN A RELEARN CYCLE (drain/charge loops to ensure the battery's health), the controller reverts to write-through mode and performance will suffer. What's more, the relearn cycles are usually automated on a schedule which may or may not happen in the middle of big traffic. So, that has to be manually disabled and manually scheduled for off-hours if it's a concern. Annoying either way. NV caches have capacitors with a sufficient charge to commit any uncommitted-to-disk data to flash. Not only is that more survivable in longer loss situations, but you don't have to concern yourself with battery death, wear-out, or relearning. All of that sounds great to me. What doesn't sound great to me is the prospect of that flash module having an issue, though. What if it's completely hosed? What if it's only partially hosed? A bit corrupted at the edges? Relearn cycles can tell when something like a simple battery is failing, but is there a similar process to verify that the flash is functional? I'm just far more trusting of a battery, warts and all. I know the card's RAM can fail, the card itself can fail - that's common territory, though. In case you didn't guess, yeah, I've experienced a shocking-to-me amount of flash/SSD/etc. failure :)

  • Is a selector like *+* safe to use?

    - by mcmullins
    I recently came across this CSS selector while trying to find a way to easily space out major blog elements such as paragraphs and images. An example of its use would be something like this: .post *+* {margin-top: 15px;} /* or... */ .post > *+* {margin-top: 15px;} /* if you don't want the margin to apply to nested elements */ At first glance, it seemed pretty useful. So my question is: What downsides are there to using these selectors? Specifically: What's the browser support like for this? Are there any cases you wouldn't want an even margin spacing between elements in an article and if not, is it easier to declare this first and then overwrite or simply declare each element individually? Does this have performance issues since you're selecting everything twice?

  • Python - a clean approach to this problem?

    - by Seafoid
    Hi, I am having trouble picking the best data structure for solving a problem. The problem is as below: I have a nested list of identity codes where the sublists are of varying length. li = [['abc', 'ghi', 'lmn'], ['kop'], ['hgi', 'ghy']] I have a file with two entries on each line; an identity code and a number. abc 2.93 ghi 3.87 lmn 5.96 Each sublist represents a cluster. I wish to select the i.d. from each sublist with the highest number associated with it, append that i.d. to a new list and ultimately write it to a new file. What data structure should the file with numbers be read in as? Also, how would you iterate over said data structure to return the i.d. with the highest number that matches the i.d. within a sublist? Thanks, S :-)

  • How to display icons next to a select1 control with xxforms:tree appearance

    - by user557060
    Hi, I display a list of items via select1 control using xxforms:tree appearance. They are displayed via a code block like: <xforms:itemset nodeset="instance('dataInstance')/*"> <xforms:label ref="fn:concat(./NAME,', ','ID: ',./ID)"/> <xforms:value ref="./ID"/> </xforms:itemset> </xforms:select1> I want to display two icons for each item on the same row as the item: one icon for deleting and one for editing that item, which would all invoke XPL with the item ID as the parameter. The question, how do I render those icons - does itemset support nested trigger elements? If not, how do I go about achieving it (clicking on the item results in an action other than edit or delete, so cannot use that; can show delete/edit on the page shown when user clicks on the item, but want to save that one click if the user just wants to delete the item for example). Thanks.

  • ReportViewer with DataSets

    - by bearrito
    I have a question about the following architecture. I am importing my business objects into my client using WCF. Due to the complexity of the business objects ( nested hierarchies ) I want to flatten out my business objects into a dataset/datatable. There are many more tutorials and how-to on successfully using datatables in a report than with a business object so I am pretty attached to this idea. My question is what sort of DataSet should I use? Strongly typed or not? If strongly typed how do I import my business objects into the Datatables?

  • How to access a method of a closure's parent object?

    - by Bytecode Ninja
    I have defined a class named MyClass and I have defined two methods myMethod1 and myMethod2 for it: function MyClass() {} MyClass.prototype.myMethod1 = function() {...}; MyClass.prototype.myMethod2 = function() {...}; Inside myMethod1, I use jQuery and there's a callback closure defined there: MyClass.prototype.myMethod2 = function() { $.jQuery({success: function(data) { this.myMethod2(); }, ...}); } Now the problem is that this no longer is referring to MyClass. The question is how can I refer to it? At the moment I have assigned it to a variable named thisObj and access it this way: MyClass.prototype.myMethod2 = function() { var thisObj = this; $.jQuery({success: function(data) { thisObj.myMethod2(); }, ...}); } Is there a better way to access MyClass.this from the closure nested in myMethod2? Thanks in advance.

  • Get name and value from the input tag

    - by DroidIn.net
    Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

  • Notepad++ Move Caret Outside Bracket

    - by marknadal
    I've searched everywhere and can't find an answer to something incredibly simple and useful for Notepad++. When using autoclose, the cursor gets stuck inside, which is good until I've finished typing the parameters. How do I get the caret to jump outside of the currently nested autoclosed element? Regardless of it being (), {}, [], "", '', ? CTRL+B does does something similar, but it goes to the inside of the left bracket first, and then to the outside of the right bracket, which is where I want to be. This only works for brackets though, not tags and qoutations Hitting CTRL+B twice is cumbersome and manually hitting "right arrow" requires too much hand motion while coding. And finally, is there anyway I can map this to "SHIFT+Space"?

  • LoadViewState not fired on my user control

    - by Jeremy
    I have a user control nested in a repeater. Inside my user control I have another repeater and in that I have a panel. I am trying to override the LoadViewState event of my user control and dynamically add controls to the panel. I want to do it in the LoadViewState so that the dynamic controls get added before the viewstate gets loaded, so they retain their values after post backs. For some reason the LoadViewState event on the user control (ascx) is not firing. Is there some way to force it to fire, or is there another method I could use? I have ruled out the user controls repeater databind event, because I need it to work even if data binding isn't happening and I can't do it on the repeaters item created event either because the child panel and inner html doesn't exist yet.

  • IE6 Overflow Issue

    - by Nimbuz
    <div style="float:left; width:50%;"> div 1 <div style="position:absolute; width:105%">nested element</div> </div> <div style="float:left; width:50%;"> div 2 </div If an element exceeds the width of its floated parent element, the next element is pushed down unless I apply overflow:hidden on both floated elements, which defeats the purpose because I DO NOT want to hide the overflowing content. Is there any fix for it?

  • Python - alternative to list.remove(x)?

    - by Seafoid
    Hi, I wish to compare two lists. Generally this is not a problem as I usually use a nested for loop and append the intersection to a new list. In this case, I need to delete the intersection of A and B from A. A = [['ab', 'cd', 'ef', '0', '567'], ['ghy5'], ['pop', 'eye']] B = [['ab'], ['hi'], ['op'], ['ej']] My objective is to compare A and B and delete A intersection B from A, i.e., delete A[0][0] in this case. I tried: def match(): for i in A: for j in i: for k in B: for v in k: if j == v: A.remove(j) list.remove(x) throws a ValueError.

  • Nesting a SharePoint Webpart inside of a User Control

    - by jlech
    I know it's usually the other way around, but I have some extenuating requirements that must be met (read as "No one bothered to do the research and now I have to bail them out") I have a standard user control (ascx) that is to be imported into a SharePoint 2007 website. Due to a design constraint, a sharepoint web part that is also needed has to be nested inside of this user control. So in other words, the user control would have to look something like this: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="foo.ascx.cs" Inherits="foo" %> <div id="container"> ...snipped... <!-- SharePoint web part goes here --> ...snipped... </div> Any help would be appreciated. Thanks!

  • Monitor programs accessing my keyboard?

    - by Anti Earth
    As of a few days ago, my computer is behaving 'erratically'. When I am typing, my pointer will randomly move to another place in the text and start typing a semi-random string of characters. ("gvyfn" is common; It has typed this about 8 times whilst I composed all the text above) It often highlights part of or all the text and overwrites it. It sometimes goes into loops of pressing Control-alt-delete down, bringing up Windows 7 menu thing. It sometimes even messes with mouseclicks; they have unexpected results, like requesting admin priveledges from applications, instead of switching to their window. I believe this is because it is holding a alt-function key down. This behaviour happens periodically, in waves. It might subside for an hour, then continue to haunt me. I believe it to be a virus or malicious program. My anti-virus (Symantec) and multiply MS rootkit removers could not find anything suspicious. I've noticed that sometimes it re-maps keys, and types gibberish when I press certain keys (though no pattern is evident). I believe a malicious program has installed a keyhook on my computer. I'm wondering... - Is there a way to let me view which programs are emulating keystrokes? - Is there a way to view what keyboard hooks are installed? (I'm also at liberty to try any other techniques to remove this blasted thing. It is easily the most fustrating computer problem I've encountered). Thanks!

  • Is there a way to load multiple app.configs in memory?

    - by Dave
    I have a windows service that loads multiple "handlers" written by different developers. The windows service exe has it's own app.config which I need. I'm trying to make it so that each developer can provide their own app.config along with their handler code. However, it seems an exe can only have one app.config. However, ASP.NET seems to support nested web.config... That's not exactly what I want, but I don't even know how I would get that to work in a windows service. Anyone come across this before or have any ideas?

  • ASP.NET Template Selector/Builder - Dynamic CMS

    - by Ugene
    I am currently building my own CMS for various reasons that could take a long to explain... However i am looking for a dynamic solution to create templates for pages within the CMS and all areas must be editable via the administration area, maybe large text areas broken into multiple areas, text and image area on a page etc. Following on from the above i would like to create the following: Create a new page (selecting a pre-defined template like below) http://img525.imageshack.us/img525/9872/nestedpages.png and then upon editing the page it would have created as many text editors required for each editable region or a file upload control for an image area for example. i am thinking of using nested masterpages for the design elements, just unsure the best-practice way to achieve the above (db structure etc) I somehow hope this provides enough information but are happy to answer any questions you may have. Thanks

  • PHP IF statement not taking variable into account!

    - by Jess
    I have a tabled view in a while loop, where a user can view information on books. For example, book ISBN, book name, read status... Basically, when the user sets their 'readstatus' to 'complete' I want that specific table row to become grey! The logic is very straight forward, however I can't get my IF statement to recognise this: $readstatus = $_GET['readstatus']; if ($readstatus == 'complete') { echo '<tr class="completed">'; } else if ($readstatus != 'complete') { echo '<tr class="reading">'; } I'm obviously doing something wrong here, but all I need is the CSS class of the table row to change if the value of 'readstatus' = 'complete', if not, then output the default CSS table row color ('reading') Should I be putting $result as the variable or something? I have this coming just before my nested IF statement: $result = mysql_query($sql, $connection) or die ("Couldn't perform query $sql <br />".mysql_error()); while($row = mysql_fetch_array($result)) { ?>

  • How do I wrap a repeatbale set of elements in jQuery?

    - by Globalz
    In jQuery how would I go about wrapping a repeatable set of elements with a div? For example I have: img h4 p img h4 p img h4 p I need to wrap each img, h4, p set with a div class="container". So it will look like: <div> class="container" img h4 p </div> <div> class="container" img h4 p </div> <div> class="container" img h4 p </div> Any ideas on how I can achieve this as its driving me nuts! I keep getting nested div.containers! Thanks!

  • ASP.Net website makes browser load unwanted (non-referenced) plugins

    - by alec0001
    I've found that some of my ASP.Net web apps prompt the browser to load plugins that I'm not explicitely using and certainly haven't deliberately referenced in the project settings. Two that come to mind are for MS MediaPlayer and the "SVG Viewer for Netscape". The only commonality I've determined so far is that the two sites/apps affected both use Master pages (nested in some cases). We don't use SVG file types (just the normal mix of jpg/gif/png) and no video/audio (not yet anyway). Can anyone provide a hint as to where the references for these might be creeping in? e.g. Is it a server-level include? Or a .Net runtime default when using master pages? Does anyone else even experience this, or is it just me? No urgency, I'd just like to remove it if possible. Thanks. Al

  • Find node level in a tree

    - by Álvaro G. Vicario
    I have a tree (nested categories) stored as follows: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci I need to feed my client-side language (PHP) with node information (child+parent) so it can build the tree in memory. I can tweak my PHP code but I think the operation would be way simpler if I could just retrieve the rows in such an order that all parents come before their children. I could do that if I knew the level for each node: SELECT category_id, category_name, parent_id FROM category ORDER BY level -- No `level` column so far :( Can you think of a way (view, stored routine or whatever...) to calculate the node level? I guess it's okay if it's not real-time and I need to recalculate it on node modification.

  • Using generic type from other generic parameter

    - by DEHAAS
    Hi, I have a question about .net generics. Consider the following code: public class Test<TKey> { TKey Key { get; set; } } public class Wrapper<TValue, TKey> where TValue : Test<TKey> { public TValue Value { get; set; } } Now, when using this code, I could do something like this: Wrapper<Test<int>, int> wrapper = new Wrapper<Test<int>, int>(); The int type parameter has to be provided twice. Is it possible to modify the Wrapper definition, to require TValue to be a generic type, and use this 'nested' generic type parameter insted of the TKey type parameter?

  • How can I find all the trunks from several different Subversion servers?

    - by SylanderXS
    We have many SVN Repo's but many of them have nested projects. I need some way of finding the trunk directories only and creating a list of them. So, the svn path to trunk might be svn://svnserver/repos/myproject/trunk or it might be svn://svnserver/repos/myproject/mysubproject/trunk I need to generate a list of /trunk directories from several different servers. Is there a method for doing that? Has anyone seen a script (sh, perl, whatever) for doing something similar? I just need a hint on how to get started.

  • In Perl, how can I iterate over the Cartesian product of multiple sets?

    - by nubie2
    I want to do permutation in Perl. For example I have three arrays: ["big", "tiny", "small"] and then I have ["red", "yellow", "green"] and also ["apple", "pear", "banana"]. How do I get: ["big", "red", "apple"] ["big", "red", "pear"] ..etc.. ["small", "green", "banana"] I understand this is called permutation. But I am not sure how to do it. Also I don't know how many arrays I can have. There may be three or four, so I don't want to do nested loop.

  • scala: how to rewrite this function using for comprehension

    - by opensas
    I have this piece of code with a couple of nasty nested checks... I'm pretty sure it can be rewritten with a nice for comprehension, but I'm a bit confused about how to mix the pattern matching stuff // first tries to find the token in a header: "authorization: ideas_token=xxxxx" // then tries to find the token in the querystring: "ideas_token=xxxxx" private def applicationTokenFromRequest(request: Request[AnyContent]): Option[String] = { val fromHeaders: Option[String] = request.headers.get("authorization") val tokenRegExp = """^\s*ideas_token\s*=\s*(\w+)\s*$""".r val tokenFromHeader: Option[String] = { if (fromHeaders.isDefined) { val header = fromHeaders.get if (tokenRegExp.pattern.matcher(header).matches) { val tokenRegExp(extracted) = header Some(extracted) } else { None } } else { None } } // try to find it in the queryString tokenFromHeader.orElse { request.queryString.get("ideas_token") } } any hint you can give me?

  • Should I convert data arrays to objects in PHP in a CouchDB/Ajax app?

    - by karlthorwald
    I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips?
