  • Is it weird or strange to make multiple WCF Calls to build a ViewModel before presenting it?

    - by Nate Bross
    Am I doing something wrong if I need code like this in a Controller? Should I be doing something differently? public ActionResult Details(int id) { var svc = new ServiceClient(); var model = new MyViewModel(); model.ObjectA = svc.GetObjectA(id); model.ObjectB = svc.GetObjectB(id); model.ObjectC = svc.GetObjectC(id); return View(model); } The reason I ask, is because I've got Linq-To-Sql on the back end and a WCF Service which exposes functionality through a set of DTOs which are NOT the Linq-To-Sql generated classes and thus do not have the parent/child properties; but in the detail view, I would like to see some of the parent/child data.

  • FluentNHibernate: multiple one-to-many relationships between the same entities.

    - by Venemo
    Hi, I'm working on a bug tracking application. There are tickets, and each ticket has an opener user and an assigned user. So, basically, I have two entities, which have two many-to-one relationships with each other. Their schematic is this: User: public class User { public virtual int Id { get; private set; } ... public virtual IList<Ticket> OpenedTickets { get; set; } public virtual IList<Ticket> AssignedTickets { get; set; } } Ticket: public class Ticket { public virtual int Id { get; protected set; } ... [Required] public virtual User OpenerUser { get; set; } public virtual User AssignedUser { get; set; } } I use FluentNHibernate's auto mapping feature. The problem is, that no matter whether relationship I set, on the side of the User, both collections always contain the same data. I guess Fluent can't tell which end of which relationship belongs to where. I googled around but haven't found anything useful. Could anyone help me, please?

  • How can I bind multiple Jquery UI Slider with "year" Select?

    - by arthur_br
    Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  • In SQL Server, can multiple inserts be replaced with a single insert that takes an XML parameter?

    - by Mayo
    So I have an existing ASP.NET solution that uses LINQ-to-SQL to insert data into SQL Server (5 tables, 110k records total). I had read in the past that XML could be passed as a parameter to SQL Server but my google searches turn up results that store the XML directly into a table. I would rather take that XML parameter and insert the nodes as records. Is this possible? How is it done (i.e. how is the XML parameter used to insert records in T-SQL, how should the XML be formatted)? Note: I'm researching other options like SQL bulk copy and I know that SSIS would be a good alternative. I want to know if this XML approach is feasible.

  • How can I prevent ADO from creating multiple SPIDs?

    - by stusmith
    I'm working on an application that creates a single ADO connection and keeps it open for the lifetime of the application. I have connection pooling turned off. (Please ignore the fact that this might not be best practice for the purposes of this question). If I spawn a new thread and use the exact same ADO connection, it uses a new SPID behind the scenes. Is there anyway to ensure an ADO connection always uses the same SPID, across all threads? (For reference the application is VC++ using ADO via COM to SQL Server).

  • Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

    - by Andrew Arrow
    Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

  • How to sort a Pandas DataFrame according to multiple criteria?

    - by user1715271
    I have the following DataFrame containing song names, their peak chart positions and the number of weeks they spent at position no 1: Song Peak Weeks 76 Paperback Writer 1 16 117 Lady Madonna 1 9 118 Hey Jude 1 27 22 Can't Buy Me Love 1 17 29 A Hard Day's Night 1 14 48 Ticket To Ride 1 14 56 Help! 1 17 109 All You Need Is Love 1 16 173 The Ballad Of John And Yoko 1 13 85 Eleanor Rigby 1 14 87 Yellow Submarine 1 14 20 I Want To Hold Your Hand 1 24 45 I Feel Fine 1 15 60 Day Tripper 1 12 61 We Can Work It Out 1 12 10 She Loves You 1 36 155 Get Back 1 6 8 From Me To You 1 7 115 Hello Goodbye 1 7 2 Please Please Me 2 20 92 Strawberry Fields Forever 2 12 93 Penny Lane 2 13 107 Magical Mystery Tour 2 16 176 Let It Be 2 14 0 Love Me Do 4 26 157 Something 4 9 166 Come Together 4 10 58 Yesterday 8 21 135 Back In The U.S.S.R. 19 3 164 Here Comes The Sun 58 19 96 Sgt. Pepper's Lonely Hearts Club Band 63 12 105 With A Little Help From My Friends 63 7 I'd like to rank these songs in order of popularity, so I'd like to sort them according to the following criteria: songs that reached the highest position come first, but if there is a tie, the songs that remained in the charts for the longest come first. I can't seem to figure out how to do this in Pandas.

  • Active Record Associations: has_one :through? Or multiple has_one's?

    - by jmccartie
    I'm brand new to Rails, so bear with me. I have 3 models: User, Section, and Tick. Each section is created by a user. My guess with this association: class Section < ActiveRecord::Base has_one :user end Next, each user can "tick" off a section -- only once. So for each tick, I have a section_id, user_id, and timestamps. Here's where I'm stuck. Does this call for a "has_one :through" association? If so, which direction? If not, then I'm way off. Which association works here? Thanks!

  • How to Create an Array from a Single Variable and Form Multiple Foreach Loops?

    - by matphoto
    I'm fairly proficient in HTML/CSS, but very new when it comes to the likes of PHP and Javascript. I've jumped headfirst into coding Wordpress shortcodes (basically php functions), and so far, through trial and error and seemingly endless browser refreshes, I've been able to figure everything out. I just hit a huge wall though, hence why I'm here. Basically, I'm trying to give an attribute a list of values like: attr="23, 95, 136, ect" The function then needs to take that attribute variable and create an array with it: $arr = array($attr); To me that seems as if it would work, but the array takes the whole list as one value instead. After doing that I want to create a foreach loop that parses each number from the list, possibly through yet another foreach loop if possible, and returns a section of code for each one, and I'm not quite sure how to pull that off either. Any feedback would be greatly appreciated.

  • How can you setup multiple WSGI apps on one server?

    - by Shakakai
    I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

  • How do I run multiple ruby scripts sequentially on my local machine?

    - by marcamillion
    I have about 5 or 6 ruby scripts I want to run, right after each other. These are all on my local machine (OS X) and won't be run on a server. Each takes about 15 minutes to run, and I don't want to have to wait for each one to finish before running the others manually. Without using something as heavy as delayed_job or some other queueing gem, how can I achieve this? Or should I go through the hassle of setting up sidekiq or something else? Thanks. P.S. It would be nice to restart the script if one of them times out (I am doing web crawling, so keeping an HTTP connection open sometimes gives me issues) - which happens occasionally.

  • Can you dynamically combine multiple conditional functions into one in Python?

    - by erich
    I'm curious if it's possible to take several conditional functions and create one function that checks them all (e.g. the way a generator takes a procedure for iterating through a series and creates an iterator). The basic usage case would be when you have a large number of conditional parameters (e.g. "max_a", "min_a", "max_b", "min_b", etc.), many of which could be blank. They would all be passed to this "function creating" function, which would then return one function that checked them all. Below is an example of a naive way of doing what I'm asking: def combining_function(max_a, min_a, max_b, min_b, ...): f_array = [] if max_a is not None: f_array.append( lambda x: x.a < max_a ) if min_a is not None: f_array.append( lambda x: x.a > min_a ) ... return lambda x: all( [ f(x) for f in f_array ] ) What I'm wondering is what is the most efficient to achieve what's being done above? It seems like executing a function call for every function in f_array would create a decent amount of overhead, but perhaps I'm engaging in premature/unnecessary optimization. Regardless, I'd be interested to see if anyone else has come across usage cases like this and how they proceeded. Also, if this isn't possible in Python, is it possible in other (perhaps more functional) languages?

  • Is there a script that would allow me to edit multiple files as if they are one file in VIM?

    - by somewire
    I prefer to edit in one large file rather than many independent files, but due to limitations in languages, source control, and the preference of team mates I need to output to many files. What I'm looking for would recurse through all the files in a source directory and generate a single file to edit in VIM, with special file seperator markers. On save it would save the the changes to the correct file(s) ideally in a smart manner, based only on changes made. Does something like this exist?

  • how can i make sure only a single record is inserted when multiple apache threads are trying to acce

    - by Ed Gl
    I have a web service (xmlrpc service to be exact) that handles among other things writing data into the database. Here's the scenario: I often receive requests to either update or insert a record. What I would do is this: If the record already exists, append to the record, If not, create a new record The issue is that there are certain times I would get a 'burst' of requests, which spawns several apache threads to handle the request. These 'bursts' would come within less than milliseconds of each other. I now have several threads performing #1 and #2. Often two threads would would 'pass' number #1 and actually create two duplicate records (except for the primary key). I'd like to use some locking mechanism to prevent other threads from accessing the table while the other thread finishes its work. I'm just afraid of using it because if something happens I don't want to leave the table locked. Is there a solid way of handling this? I'm open to using locks if I can do it properly. Thanks,

  • nodejs, mongodb - How do I operate on data from multiple queries?

    - by Ryan
    Hi all, I'm new to JS in general, but I am trying to query some data from MongoDB. Basically, my first query retrieves information for the session with the specified session id. The second query does a simple geospacial query for documents with a location near the specified location. I'm using the mongodb-native javascript driver. All of these query methods return their results in callbacks, so they're non-blocking. This is the root of my troubles. What I'm needing to do is retrieve the results of the second query, and create an Array of sessionIds of all the returned documents. Then I'm going to pass those to a function later. But, I can't generate this array and use it anywhere outside the callback. Does anyone have any idea how to properly do this? http://dpaste.org/wXiE/

  • Python Logging across multiple classes and files; how to configure so as to be easily disabled?

    - by mellort
    Currently, I have osmething like this in all of my classes: # Import logging to log information import logging # Set up the logger LOG_FILENAME = 'log.txt' logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG) This works well, and I get the output I want, but I would really like to have all this sort of information in one place, and be able to just do something like import myLogger and then start logging, and then hopefully be able to just go into that file and turn off logging when I need an extra performance boost. Thanks in advance

  • How can I build a voting system to support multiple types of objects to vote on?

    - by Kyle Hayes
    I'm really looking for something very similar to the way SO is setup where a few different kinds of things can be voted on (questions AND answers). What kind of DB schema, generally, could I use to support voting on many different kinds of objects? Would I have a single Vote table that would have references to other objects in the database? Or do I have to have or should have a separate vote table for each of the objects I would like to vote on.

  • JQuery multiple-choice quiz script: how to ensure the correct answer is available?

    - by DavidR
    I have a function. I pass to it an object with a list of questions and answers. I generate a random number from a range equal to the number of questions in the object. The script check to see if that question has been asked, and if not, it asks it, the correct answer is then passed to a variable correct. I want to give 4 possible answers, each one randomly selected from the list of possible answers. I have this. I just want to know what is the best way to ensure that the correct answer is placed in the list. So far, this is what I have: it puts four answers into four targeted boxes. I want to ensure that the correct answer is in a randomly selected box. function getRandom(limit) { return Math.floor(Math.random() * limit ) } $("#answers > .answer").each(function(i){ r = getRandom(total_questions); $(this).text(answers[r]) });

  • Defining multiple VBA objects within one function or sub-routine?

    - by Harokitty
    I have the following VBA code: Option Explicit Private a(2) as Double Private b(2) as Double Public Function Hello(X1 As Double, X2 As Double) As Double a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2 Hello = a(1)+a(2)+b(1)+b(2) End Function Within the function Hello I have defined a(1),a(2),b(1),b(2). However, I want to make some function or sub-routine that accepts X1 and X2 as arguments and spits out the values for a(1),a(2),b(1),b(2). This is because I use the above definitions for a(1),a(2),b(1),b(2) in about 20 functions in my module and would like to avoid having to do the following in each function that I use thesis in: a(1) = X1 + X2 a(2) = X1/X2 b(1) = X1 b(2) = X2^2
