  • Getting the value from an array in the model in rails

    - by slythic
    Hi all, I have a relatively simple problem. I have a model named Item which I've added a status field. The status field will only have two options (Lost or Found). So I created the following array in my Item model: STATUS = [ [1, "Lost"], [2, "Found"]] In my form view I added the following code which works great: <%= collection_select :item, :status, Item::STATUS, :first, :last, {:include_blank => 'Select status'} %> This stores the numeric id (1 or 2) of the status in the database. However, in my show view I can't figure out how to convert from the numeric id (again, 1 or 2) to the text equivalent of Lost or Found. Any ideas on how to get this to work? Is there a better way to go about this? Many thanks, Tony

  • jQuery: Post form to a modal window for previewing the entered data

    - by superUntitled
    I am looking for a way to use jQuery to allow a user to look at a modal window "preview" of a form before they submit the form to be saved. I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window. I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this? This is what I am currently using: <script language="JavaScript"> function preview(form) { form.target='_blank'; form.action='http://example.com/preview.php'; form.submit(); } </script> <input type="button" value="preview" onclick='preview(this.form)'>

    Hey, I have two tables in one DB, one called Cottages and one called Hotels. In both tables they have the same named fields. I basically have a search bar that i want it to search in both of the fields in both of the tables. (the two fields being called "Name" and "Location" SO far I have $sql = mysql_query("SELECT * FROM Cottages WHERE Name LIKE '%$term%' or Location LIKE '%$term%' LIMIT 0, 30"); But this only searches the Cottages table, how can I make it search both the cottages and hotel tables?

  • Categorized SharePoint Discussion - default category to parents category on reply.

    - by Greg Ogle
    I have a Discussion Board in a SharePoint site which has an additional column named Category. When a new discussion is created, it prompts for Category, and of course this is by design. The problem is that when the discussion is replied to, it prompts for the category again. How can I separate the reply functionality so that the Category is not prompted and the Category is set to that of the discussion under which it resides? I attempted to edit a copy of NewForm.aspx in SharePoint Designer, but you can only edit which WebPart it is using, not which fields are displayed.

  • iphone detailtext in UITableView question

    - by Rob
    So, I am able to create an array that populates the fields of the Table, but am having troubles creating the subtext that appears below the main fields. I currently have: - (void)viewDidLoad { [super viewDidLoad]; listOfForms = [[NSMutableArray alloc] init]; [listOfForms addObject:@"First Form"]; } and then: NSString *cellValue = [listOfDAForms objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; in the cellForRowAtIndexPath portion. Why can't I add: listOfNames = [[NSMutableArray alloc] init]; [listOfNames addObject:@"Named Form"]; and NSString *cellSubscript = [listOfNames objectAtIndex:indexPath.row]; cell.detailTextLabel.text = cellSubscript; in order to make the little subview work? What am I doing wrong?

  • How to initialise an array inside a struct without doing each element separately? (C++)

    - by Janet
    My questions are in the code, but basically i want to know how/if I can do the two commented out lines? I know I can do it in a constructor but I don't want to! struct foo { int b[4]; } boo; //boo.b[] = {7, 6, 5, 4}; // <- why doesn't this work? (syntax error : ']') //boo.b = {7, 6, 5, 4}; // <- or else this? (syntax error : '{') boo.b[0] = 7; // <- doing it this way is annoying boo.b[1] = 6; // : boo.b[2] = 5; // : boo.b[3] = 4; // <- doing it this way is annoying boo.b[4] = 3; // <- why does this work! (Using: C++, Visual Studio 2005.)

  • Neo4j+Gremlin : Trouble with T.gte and floating point node attributes

    - by letronje
    For a type of nodes in my graph, attribute values for an attribute(named 'some_count') is either missing or an integer or a float. I'm trying to write gremlin to filter these nodes based on minimum value for this attribute. I first verified that the values are indeed present by firing the following gremlin g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).some_count Next, I tried filtering by exact value and that works and show me the matching nodes or gives an empty array if there is no match g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.eq, 120000.0d) But the following query that uses the 'greater than or equal to' comparator doesn't work. g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.gte, 1.0d) this returns nil (I'm querying via ruby/rails using Neo4j AR Adapter ) Instead of returning an empty array for no match, it returns a nil, which tells me something could be wrong with the query itself. I'm running neo4j community server 1.8. Is there a way I can ask Neo4j to log errors/queries, to see what could be going wrong ?

  • Command line tool (PDF Workflow) in OSX that detects if key is down

    - by kroko
    Hello! I'm writing a OSX PDF Workflow in ObjC and C. A single executable ("UNIX Tool" as named in the Apple reference), that reads in the spooled PDF file, does some parsing. I'd like to give more functionality by enabling a key-down event handling, meaning - when user opens print dialog in an application - and chooses to left-mouse-click on the custom made pdf workflow to run it - depending on if a keyboard key is down (i.e. option key, but "any key down" would be enough for me) when running that workflow - a decision is made in the code. I have read NSEvent and Carbon Event Manager reference and it seems that in this case (a plain unix executable + not run as root) it's not possible. Or is it? Many thanks in advance, Kroko

  • List in a Python class shares the same object over 2 different instances?

    - by zfranciscus
    I created a class: class A: aList = [] now I have function that instantiate this class and add items into the aList. note: there are 2 items for item in items: a = A(); a.aList.append(item); I find that the first A and the second A object has the same number of items in their aList. I would expect that the first A object will have the first item in its list and the second A object will have the second item in its aList. Can anyone explain how this happens ? PS: I manage to solve this problem by moving the aList inside a constructor : def __init__(self): self.aList = []; but I am still curious about this behavior

  • Zend autloading different namespaces from the same directory?

    - by Sled
    Hey guys, I have a models directory in my project, and I would like to save/files classes there with different namespaces. Example: models/User.php with classname Model_User models/Table_User.php with classname Model_Table_User For the first namespace I have this in bootstrap.php $resourceLoader->addResourceTypes(array( 'model' => array( 'namespace' => 'Model', 'path' => 'models' ) )); I can't figure out how to add the second namespace so it detects files starting with Table_ Any ideas? For now I've added a second directory named 'tables' but it's getting confusing because I have each model name twice (once in the models diretory and once in the tables directory)

  • Usage patterns/use cases for DI or when to start using it

    - by Fabian
    I'm not sure for which use cases one should to use DI in the application. I know that injecting services like PlaceService or CalculationService etc fits very well but should I also create my domain objects with DI like a User? What is if the User has only one constructor which requires a first and lastname. Is this solveable with DI? Should I use DI to create the instances for Set/List interfaces or is this pure overkill? I use guice primarily.

  • Quickest way to clone a GregorianCalendar?

    - by wds
    I'm trying to make a deep copy of an object, including a GregorianCalendar instance. I'm always wary of using clone() and it doesn't seem to have been overridden here, so I'm just doing the copy field by field. Ideally, there'd be a copy constructor, which I could use like so: GregorianCalendar newCalendar = new GregorianCalendar(oldCalendar); Unfortunately I can't find any such functionality in the API and am stuck trying to figure out which fields I need to get an exact copy. So, to make a copy of one of these calendars, how would you do it? Am I missing some simple shortcut here?

  • Bash - Adding 0's in the middle of a file name

    - by user596691
    I have a bunch of files which are named: mem0.csv mem1.csv . . . . mem153.csv . . . They are all in the same folder. When I do ls in the folder they appear in an order of mem0.csv mem1.csv mem10.csv mem100.csv . . . mem2.csv mem20.csv . . . I want to create a bash script to push 0's between mem and the number. I figure that I need to add 0's until all the filenames are of the same length only problem is that I don't know how to do this.

  • What's the equivalent in C# of this VB code on an Outlook form?

    - by wes
    Basically, how do I link an Outlook form and a C# back end? In VB you can write on the form Sub ButtonName_Click() Dim Recipients With Item.GetInspector.ModifiedFormPages("Message") Set Recipients = .Controls("To") End With End Sub which will fire whenever the button named "ButtonName" on the form is clicked and will set the variable Recipients to a string of whatever is in the To text box. Now I have a custom form, and I have a VS C# Outlook Add-in, and they're two separate things. I've got an event handler that can catch MailItem objects, but I don't know how to handle custom form button clicks or even how to access elements on the form. EDIT - Just to clarify, the custom form was created in Outlook and then its .ofs was imported into VS. Both Outlook and VS are 2010.

  • How does Rails Plugin Storage work?

    - by Kevin
    Trying to figure out how to install rails plugins manually on windows so I have a few questions. What does the directory need to be named in vendor/plugins? Is it arbitrary or is it linked to something within the plugin config files or is that what you set in the environment.rb? Once I've copied the files to the correct directory, do I always need to run something inside like init.rb or is it good to go? What's the difference between 'require' and 'include'? Thanks!

  • Problem with Refreshing data in ExpandableListView

    - by -providerivan.longin1
    Hi! My problem is when I want to refresh data in ExpandableListView while being in that current activity. I create adapter and when I want to add new data to list I call again constructor of that adapter(it is my private variable) with all new data....and then I call onContentChanged() method to redraw my list. But what happens is that I cant expand my list any more...like it is blocked or something and logcat isn't saying anything... This is the code that i call after setting new data in arraylists and maps: mAdapter = new MyExpandableListAdapter( this, groupData, R.layout.contact_list_parent, new String[] { NAME ,NUM_PHOTOS},//NUM_PHOTOS new int[] { R.id.rowText1, R.id.rowText2, R.id.photoAlbumImg }, childData, R.layout.contact_list_child, new String[] { NAME,NUM_PHOTOS}, //NUM_PHOTOS new int[] { R.id.rowText1, R.id.rowText2, R.id.photoAlbumImg } ); this.onContentChanged(); If anyone knows answer to this question please help me:) Thanks.

  • Why baseclass calls method of subclass?

    - by twlkyao
    I encounter some code like the following: BaseClass: public class BaseClass { String name = "Base"; public BaseClass() { printName(); } public void printName() { System.out.println(name + "——Base"); } } DrivedClass: public class SubClass extends BaseClass { String name = "Sub"; public SubClass() { printName(); } public void printName() { System.out.println(name + "——Sub"); } public static void main(String[] args) { new SubClass(); } } When run the code, the output is: null——Sub Sub——Sub while it should be: Base——Base Sub——Sub I wonder why the BaseClass constructor calls the SubClass method, can anybody explain this? Thanks in advance.

  • load balancer question c# asp.net

    - by Migs
    The place where I work has 2 servers and a load balancer. The setup is horrible since I have to manually make sure both servers have the same files. I know there are ways to automate this but it has not been implemented, hopefully soon (I have no control over this). I wrote an application that collects a bunch of information from a user, then creates a folder named after the email of the user in one of the servers. The problem is that I can't control in which server the folder gets created in, so let say a user goes in.. fills his stuff and his folder gets created in server 1, user goes away for a while and goes back to the site but this time the load balancer throws the user into server 2, now the user does something that needs to be saved into his folder but since it didn't created in this server an error occurs. What can I do about this? any suggestions? Thanks

  • Objective C instance variables - Newbie

    - by Dwayne King
    OK - so I'm sure my confusion here is just a result of being stuck in a "Java mindset" and not understanding how Obj C differs in this case. In Java, I can declare a variable in a class, like this, and each instance of that class will have it's own: MyClass { String myVar; MyClass() { // constructor } } In Obj C I tried to do the same thing by declaring a variable only in the .m file like this: #import "MyClass.h" @implementation MyClass NSString *testVar; @end My expectation here was that this variable has a scope limited to this class. So I created a second class (identical): #import "MySecondClass.h" @implementation MySecondClass NSString *testVar; @end What I'm seeing (and has me baffled) is that changing the variable in one class, affects the value seen in the other class. In fact, if I set a breakpoint, and then "Jump to Definition" of the variable, it takes me to th I've created an extremely small XCode project that demonstrates the problem here Nothing more humbling than moving to a new language :) Thanks in advance.

  • why LINQ 2 SQL sometime add a field like select 1 as test, others valid fields....

    I have to concat 2 linq2sql query and I have an issue since the 2 query doesn't return the same number of columns, what is weird is after a .ToList() on the queries, they can concat without problem. The reason is, for some linq2sql reason, I have 2 more column named test and test2 which come from 2 left outer join that linq2sql automatically create, something like "select 1 as test, tablefields" Is there any good reason for that? how to remove this extra "1 as test" field? here a few of examples of what it look like: google result for linq 2 sql "select 1 as test"

  • How to name variables which are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers
