  • Google Analytics data Missing for 4 days

    - by Shumaila
    I used wrong tracking id in my E-commerce tracking code for Google analytics and missed the data for few days. To add that missing data in my account I have written a short script which manually send all orders data for four days to GA account but what my concern is date : Those orders which already placed on different dates and , when if I run my script and so it will send my missing data with current date , which I do not want. ( I want to send date when that order is actually placed) do anyone help me with this ? I am really much stuck with my work here.

  • PHP class data implementation

    - by Bakanyaka
    I'm studying OOP PHP and have watched two tutorials that implement user login\registration system as an example. But implementation varies. Which way will be more correct one to work with data such as this? Load all data retrieved from database as array into a property called something like _data on class creation and further methods operate with this property Create separate properties for each field retrieved from database, on class creation load all data fields into respective properties and operate with that properties separately? Then let's say I want to create a method that returns a list of all users with their data. Which way is better? Method that returns just an array of userdata like this: Array([0]=>array([id] => 1, [username] => 'John', ...), [1]=>array([id] => 2, [username] => 'Jack', ...), ...) Method that creates a new instance of it's class for each user and returns an array of objects

  • CellC data card not recognized if I boot with it in

    - by Armien
    In 11.10 I find that I can connect to the internet via broadband connection successfully. The problem is that I cannot have the data card attached to the machine while the machine boots up. If I leave the data card in the machine during startup, the data card is not picked up and I then cannot connect to the internet. I must first boot up my machine, login, attach the data card into the usb port, wait so 30 seconds. The broadband connection name will then appear in the network dropdown at the top of the screen. An internet connect is now possible via broadband. Please let me know what must be done to fix this.

  • Using PDO for Data Management

    - by edorahg
    This question is more a design oriented question than a code specific question. I am new to PHP and I am planning to use PDO as a data access layer. Say for instance I have a class called CITY. Now if I need to create an instance of this class, what is the best technique. Should have a singleton DB access class which is used to write and read data from the db layer. OR should I delegate it to the individual class object. For example if I invoke city.save() (city is a class), then the city class will handle the saving of that city object's data into the database. Excuse my ignorance but i have a java background and therefore trying to understand what is the best design principle for data management when using php.

  • Can't view order in magento

    - by koko
    Hi, I've been setting up a fresh magento 1.4.0.1 install, working great so far. I did some test orders just to see.

  • Deserializing a complex JSON result (array of dictionaries) with TouchJSON

    - by jpm
    I did a few tests with TouchJSON last night and it worked pretty well in general for simple cases. I'm using the following code to read some JSON content from a file, and deserialize it: NSString *jsonString = [[NSString alloc] initWithContentsOfFile:@"data.json"]; NSData *jsonData = [jsonString dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary *items = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; NSLog(@"total items: %d", [items count]); NSLog(@"error: %@", [error localizedDescription]); That works fine if I have a very simple JSON object in the file (i.e. a dictionary): {"id": "54354", "name": "boohoo"} This way I was able to get access to the array of values, as I wanted to get the item based on its index within the list: NSArray *items_list = [items allValues]; NSString *name = [items_list objectAtIndex:1]; (I understand that I could have fetched the name with the dictionary API) Now I would like to deserialize a semi-complex JSON string, which represents an array of dictionaries. An example of such a JSON string is below: [{"id": "123456", "name": "touchjson"}, {"id": "3456", "name": "bleh"}] When I try to run the same code above against this new content in the data.json file, I don't get any results back. My NSLog() call says "total items: 0", and no error is coming back in the NSError object. Any clues on what is going on? I'm completely lost on what to do, as there isn't much documentation available for TouchJSON, and much less usage examples.

  • Migrating complex SVN branch hierarchy to Mercurial

    - by Christian Hang
    Our team has been using SVN for managing an application of decent size and over time a rather complex hierarchy of branches and tags has built up, which is following the basic standard layout for SVN repositories, but is more nested: |-trunk |-branches | |-releases | | |-releaseA | | `-releaseB | `-features | |-featureX | `-featureY |-tags |-releaseA | |-beta | `-RTP `-releaseB |-beta `-RTP (The feature branches are obviously temporary branches but we have to take them into consideration as it won't be feasible to close all of them at once in the near future) For several reasons but primarily because merges have been becoming an increasing pain, we are considering to switch to Mercurial. The main problem we are currently facing is migrating the existing code base without losing our history. I've tried several migration tools (e.g., yasvn2hg, hg convert and svn2hg) with yasvn2hg being the most promising, but none of them seem to be able to deal with nested hierarchies but they all assume that branches and tags are organized in one flat directory respectively. The choice between named branches or clones as the conversion target of old SVN branches is not a limiting factor in this case, as either solution would be appreciated. We are currently experimenting with both options and how they would fit into our current processes but haven't decided on one yet. I'd obviously be interested in recommendations or experiences with similar setups concerning that issue as well. So, what is the best way to convert a nested SVN branch hierarchy like this to Mercurial? Converting one branch at a time into a separate repository would be quite annoying and I am not sure if that would be the right approach in the first place, depending on how the tools handle historic merges and need to be aware of all other branches?

  • Complex Types, ModelBinders and Interfaces

    - by Kieron
    Hi, I've a scenario where I need to bind to an interface - in order to create the correct type, I've got a custom model binder that knows how to create the correct concrete type (which can differ). However, the type created never has the fields correctly filled in. I know I'm missing something blindingly simple here, but can anyone tell me why or at least what I need to do for the model binder to carry on it's work and bind the properties? public class ProductModelBinder : DefaultModelBinder { override public object BindModel (ControllerContext controllerContext, ModelBindingContext bindingContext) { if (bindingContext.ModelType == typeof (IProduct)) { var content = GetProduct (bindingContext); return content; } var result = base.BindModel (controllerContext, bindingContext); return result; } IProduct GetProduct (ModelBindingContext bindingContext) { var idProvider = bindingContext.ValueProvider.GetValue ("Id"); var id = (Guid)idProvider.ConvertTo (typeof (Guid)); var repository = RepositoryFactory.GetRepository<IProductRepository> (); var product = repository.Get (id); return product; } } The Model in my case is a complex type that has an IProduct property, and it's those values I need filled in. Model: [ProductBinder] public class Edit : IProductModel { public Guid Id { get; set; } public byte[] Version { get; set; } public IProduct Product { get; set; } }

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.

  • Webservice complex types and class inheritance

    - by pygorex1
    Using the following Webservice definition using aClientArgs as a complex type: [System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client> So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

  • Best practices to develop and maintaing code for complex JQuery/JQueryUI based applications

    - by dafi
    I'm working on my first very complex JQuery based application. A single web page can contain hundreds of JQuery related code for example to JQueryUI dialogs. Now I want to organize code in separated files. For example I'm moving all initialization dialogs code $("#dialog-xxx").dialog({...}) in separated files and due to reuse I wrap them on single function call like dialogs.js function initDialog_1() { $("#dialog-1").dialog({}); } function initDialog_2() { $("#dialog-2").dialog({}); } This simplifies function code and make caller page clear $(function() { // do some init stuff initDialog_1(); initTooltip_2(); }); Is this the correct pattern? Are you using more efficient techniques? I know that splitting code in many js files introduces an ugly band-bandwidth usage so. Does exist some good practice or tool to 'join' files for production environments? I imagine some tool that does more work than simply minimize and/or compress JS code.

  • Building a complex view with Three20 - resources?

    - by psychotik
    I'm using three20 for most of my iPhone app. One of the views I need to create is relatively complex. It needs a top bar (under the nav bar) with some controls and label, an image view below this bar (which occupies most of the body) and another bottom bar with more controls and labels (above the tab bar control). I don't have much UI experience - my only experience with anything UI is laying stuff out using CSS, etc on websites. Apple's online doc seems to assume that the reader knows a bunch about rectangles, layouts, frames, etc or is using InterfaceBuilder. And three20 isn't too well documented either. So my question is: Is it possible to design something like what I describe in IB and then still have a three20-based app use it? If so, any tips/pointers on how would be much appreciated. Can you point me to some documentation that explain how views/controls etc are rendered. I'm pretty sure I can figure it out if I find some decent explanation/tutorial for it.

  • ASP.Net MVC vs ASP.Net for Complex workflows

    - by Grant Sutcliffe
    I have just become involved in migrating a series of complex workflows with InfoPath UIs to Web-based UIs. I am new to ASP.Net MVC but have started to evaluate it as the technology versus classic ASP.Net for the job. As is typical of most workflows, in each state there are a number of business rules that determine (a) who can view what content; (2) who can edit what content; (3) what the user action options might be (Edit; Reject; Approve), etc. In essence, there is a lot of logic that needs to be applied to each request before presenting the appropriate view. Being more experienced in ASP.Net, I know that presenting the form(s) as required can be easily achieved through code behind pages (enable / disable / hide fields). I have not seen how this can be achieved with ASP.Net MVC (but am realising that new thinking is required of me when working with MVC - ‘Give only the content on a particular View + limited user action options’). Therefore, if using ASP.Net MVC, it looks like I would need to create a lot of views. Much of the content in each view would be the same. Only field enabled status or buttons would differ in most instances for these views in each state. For example: Step01Initiate (‘Has Save’ button); Step01OriginatorView (has ‘Edit’ Button) ; Step01OriginatorEdit (has ‘Save’ button); Step01Review (has ‘Accept’ / ‘Reject’ buttons); Step01ReviewReject (for reviewer notes; has ‘Save’ / ‘Cancel’ buttons). With workflows of up to six states, this would result in a lot of views. I can see the advantages of choosing ASP.MVC (1) ‘thin’ Views in terms of content; and (2) with logic consolidation in Controllers and different Models. Am I thinking along the right lines in terms of applying the MVC – ‘plenty of views’; or is there a better way to achieve my goal (using ASP.Net MVC or classic ASP.Net)?

  • Complex derived attributes in Django models

    - by rabidpebble
    What I want to do is implement submission scoring for a site with users voting on the content, much like in e.g. reddit (see the 'hot' function in http://code.reddit.com/browser/sql/functions.sql). My submission model currently keeps track of up and down vote totals. Currently, when a user votes I create and save a related Vote object and then use F() expressions to update the Submission object's voting totals. The problem is that I want to update the score for the submission at the same time, but F() expressions are limited to only simple operations (it's missing support for log(), date_part(), sign() etc.) From my limited experience with Django I can see 4 options here: extend F() somehow (haven't looked at the code yet) to support the missing SQL functions; this is my preferred option and seems to fit within the Django framework the best define a scoring function (much like reddit's 'hot' function) in my database, and have Django use the value of that function for the value of the score field; as far as I can tell, #2 is not possible wrap my two step voting process in a suitably isolated transaction so that I can calculate the voting totals in Python and then update the Submission's voting totals without fear that another vote against the submission could be added/changed in the meantime; I'm hesitant to take this route because it seems overly complex - what is a "suitably isolated transaction" in this case anyway? use raw SQL; I would prefer to avoid this entirely -- what's the point of an ORM if I have to revert to SQL for such a common use case as this! (Note that this coming from somebody who loves sprocs, but is using Django for ease of development.) Before I embark on this mission to extend F() (which I'm not sure is even possible), am I about to reinvent the wheel? Is there a more standard way to do this? It seems like such a common use case and yet in an hour of searching I have yet to find a common solution...

  • Managing/Storing complex application form

    - by mickyjtwin
    I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

  • Unit test complex classes with many private methods

    - by Simon G
    Hi, I've got a class with one public method and many private methods which are run depending on what parameter are passed to the public method so my code looks something like: public class SomeComplexClass { IRepository _repository; public SomeComplexClass() this(new Repository()) { } public SomeComplexClass(IRepository repository) { _repository = repository; } public List<int> SomeComplexCalcualation(int option) { var list = new List<int>(); if (option == 1) list = CalculateOptionOne(); else if (option == 2) list = CalculateOptionTwo(); else if (option == 3) list = CalculateOptionThree(); else if (option == 4) list = CalculateOptionFour(); else if (option == 5) list = CalculateOptionFive(); return list; } private List<int> CalculateOptionOne() { // Some calculation } private List<int> CalculateOptionTwo() { // Some calculation } private List<int> CalculateOptionThree() { // Some calculation } private List<int> CalculateOptionFour() { // Some calculation } private List<int> CalculateOptionFive() { // Some calculation } } I've thought of a few ways to test this class but all of them seem overly complex or expose the methods more than I would like. The options so far are: Set all the private methods to internal and use [assembly: InternalsVisibleTo()] Separate out all the private methods into a separate class and create an interface. Make all the methods virtual and in my tests create a new class that inherits from this class and override the methods. Are there any other options for testing the above class that would be better that what I've listed? If you would pick one of the ones I've listed can you explain why? Thanks

This is how the xml for customfields should look like ( the attribute array is nesseray but I don't understand how to create it): <custom_fields type="array"> <custom_field name="Standby Reason" id="6"> <value/> </custom_field> <custom_field name="Close Date" id="84"> Class Ticket public class Ticket { [XmlElement("custom_fields")] public CustomFields Custom_fields { get; set; } Class CustomFields [Serializable] public class CustomFields { [XmlAttribute("array")] public List<CustomField> custom_field { get; set; } Class CustomField [Serializable] public class CustomField { [XmlIgnore] public string Name { get; set; } [XmlElement] public int Id { get; set; } [XmlElement] public string Value { get; set; }

  • Representing complex scheduled reoccurance in a database

    - by David Pfeffer
    I have the interesting problem of representing complex schedule data in a database. As a guideline, I need to be able to represent the entirety of what the iCalendar -- ics -- format can represent, but in a database. I'm not actually implementing anything relating to ics, but it gives a good scope of the type of rules I need to be able to model. I need to allow allow representation of a single event or a reoccurring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November annually, or the 25th of December annually, or every two weeks starting November 2 and continuing until September 8 the following year. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For example, given January 15, 2010 at 10:00 AM through January 15, 2010 at 11:00 AM, find all schedules that match at least part of that time. (i.e. a schedule that covers 10:30 - 11:00 still matches.) Any suggestions? I looked at http://stackoverflow.com/questions/1016170/how-would-one-represent-scheduled-events-in-an-rdbms but it doesn't cover the scope of the type of reoccurance rules I'd like to model.

  • Modeling complex hierarchies

    - by jdn
    To gain some experience, I am trying to make an expert system that can answer queries about the animal kingdom. However, I have run into a problem modeling the domain. I originally considered the animal kingdom hierarchy to be drawn like -animal -bird -carnivore -hawk -herbivore -bluejay -mammals -carnivores -herbivores This I figured would allow me to make queries easily like "give me all birds", but would be much more expensive to say "give me all carnivores", so I rewrote the hierarchy to look like: -animal -carnivore -birds -hawk -mammals -xyz -herbivores -birds -bluejay -mammals But now it will be much slower to query "give me all birds." This is of course a simple example, but it got me thinking that I don't really know how to model complex relationships that are not so strictly hierarchical in nature in the context of writing an expert system to answer queries as stated above. A directed, cyclic graph seems like it could mathematically solve the problem, but storing this in a relational database and maintaining it (updates) would seem like a nightmare to me. I would like to know how people typically model such things. Explanations or pointers to resources to read further would be acceptable and appreciated.
