• How to float a <div> echoed in the footer over a <div> located elsewhere (PHP/jQuery/HTML/CSS)

  - by PlasmaFlux

  Hello All! I'm embarking on a major project, but am stuck on a tiny issue at the very start. I'll try to be as concise as possible. I have a PHP script that will be echoing into the footer of the page (the last stuff before a bunch of s containing visible buttons and s containing hidden dialog boxes. The plan is to have the buttons float in the upper-right corner of corresponding s in the main content area of the page. i.e. - button-1 echoed into the footer will float in the corner of content-box-1, and will be tied to the hidden 'dialog-1'. I'll be using jQuery and jQuery UI Dialog throughout the page(s). I'm not sure if that's particularly relevant to this question, but thought it worth mentioning just in case. So my question, put simply, is how do I echo a Button 1 into the footer with PHP, but have it float in the upper-right corner (with maybe 5px margin) of Content 1 is full of content? A picture says a thousand words: As shown above, I want the little blue gear button things in the corner of content pieces, locked and loaded with hidden s containing dialog boxes. Again, the catch is that all buttons and hidden divs will be the very last items echoed into the page footer. I've found plenty of info on how to float divs on top of divs, but all the examples I saw showed the s in close proximity to each other in the page source; not with a hundred lines of source code between the two s I'm not sure if the solution is pure CSS, pure jQuery/jQueryUI or a combination of the two. Any advice will be much appreciated. Thanks!

• Best pattern to load enumerated values from DAL using WCF RIA Services

  - by Dale Halliwell

  I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?

• C# -Interview Question Anonymous Type

  - by Amutha

  Recently i was asked to prove the power of C# 3.0 in a single line( might be tricky) i wrote new int[] { 1, 2, 3 }.Union(new int[]{10,23,45}). ToList().ForEach(x => Console.WriteLine(x)); and explained you can have (i) anonymous array (ii) extension method (iii)lambda and closure all in a single line.I got spot offer. But..... The interviewer asked me how will you convert an anonymous type into know type :( I am 100% sure ,we can not do that.The interviewer replied there is 200% chance to do that if you have a small work around.I was clueless. As usual,I am waiting for your valuable reply(Is it possible?).

• Ubuntu: pip not working with python3.4

  - by val_

  Trying to get pip working on my Ubuntu pc. pip seems to be working for python2.7, but not for others.

• Why can't I build this Javascript object?

  - by Alex Mcp

  I have an object I'm trying to populate from another object (that is, iterate over a return object to produce an object with only selected values from the original). My code looks like this: var collect = {}; function getHistoricalData(username){ $.getJSON("http://url/" + username + ".json?params", function(data){ for (var i=0; i < data.length; i++) { console.log(i); collect = { i : {text : data[i].text}}; $("#wrap").append("<span>" + data[i].text + "</span><br />"); }; console.log(collect); }); } So I'm using Firebug for debugging, and here's what I know: The JSON object is intact console.log(i); is showing the numbers 1-20 as expected When I log the collect object at the end, it's structure is this: var collect = { i : {text : "the last iteration's text"}}; So the incrementer is "applying" to the data[i].text and returning the text value, but it's not doing what I expected, which is create a new member of the collect object; it's just overwriting collect.i 20 times and leaving me with the last value. Is there a different syntax I need to be using for assigning object members? I tried collect.i.text = and collect[i].text = and the error was that whatever I tried was undefined. I'd love to know what's going on here, so the more in-depth an explanation the better. Thanks!

• Linq duplicate removal with a twist

  - by Danthar

  I got a list that contains al the status items of each order. The problem that i have is that i need to remove all the items of which the status - logdate combination is not the highest. e.g var inputs = new List<StatusItem>(); //note that the 3th id is simply a modifier that adds that amount of secs //to the current datetime, to make testing easier inputs.Add(new StatusItem(123, 30, 1)); inputs.Add(new StatusItem(123, 40, 2)); inputs.Add(new StatusItem(123, 50, 3)); inputs.Add(new StatusItem(123, 40, 4)); inputs.Add(new StatusItem(123, 50, 5)); inputs.Add(new StatusItem(100, 20, 6)); inputs.Add(new StatusItem(100, 30, 7)); inputs.Add(new StatusItem(100, 20, 8)); inputs.Add(new StatusItem(100, 30, 9)); inputs.Add(new StatusItem(100, 40, 10)); inputs.Add(new StatusItem(100, 50, 11)); inputs.Add(new StatusItem(100, 40, 12)); var l = from i in inputs group i by i.internalId into cg select from s in cg group s by s.statusId into sg select sg.OrderByDescending(n => n.date).First() ; This creates a list that returnes me the following: order 123 status 30 date 4/9/2010 6:44:21 PM order 123 status 40 date 4/9/2010 6:44:24 PM order 123 status 50 date 4/9/2010 6:44:25 PM order 100 status 20 date 4/9/2010 6:44:28 PM order 100 status 30 date 4/9/2010 6:44:29 PM order 100 status 40 date 4/9/2010 6:44:32 PM order 100 status 50 date 4/9/2010 6:44:31 PM This is ALMOST correct. However that last line which has status 50 needs to be filtered out as well because it was overruled by status 40 in the historylist. U can tell by the fact that its date is lower then the "last" status-item with the status 40. I was hoping someone could give me some pointers because im stuck.

• Dependecy Injection with Massive ORM: dynamic trouble

  - by Sergi Papaseit

  I've started working on an MVC 3 project that needs data from an enormous existing database. My first idea was to go ahead and use EF 4.1 and create a bunch of POCO's to represent the tables I need, but I'm starting to think the mapping will get overly complicated as I only need some of the columns in some of the tables. (thanks to Steven for the clarification in the comments. So I thought I'd give Massive ORM a try. I normally use a Unit of Work implementation so I can keep everything nicely decoupled and can use Dependency Injection. This is part of what I have for Massive: public interface ISession { DynamicModel CreateTable<T>() where T : DynamicModel, new(); dynamic Single<T>(string where, params object[] args) where T : DynamicModel, new(); dynamic Single<T>(object key, string columns = "*") where T : DynamicModel, new(); // Some more methods supported by Massive here } And here's my implementation of the above interface: public class MassiveSession : ISession { public DynamicModel CreateTable<T>() where T : DynamicModel, new() { return new T(); } public dynamic Single<T>(string where, params object[] args) where T: DynamicModel, new() { var table = CreateTable<T>(); return table.Single(where, args); } public dynamic Single<T>(object key, string columns = "*") where T: DynamicModel, new() { var table = CreateTable<T>(); return table.Single(key, columns); } } The problem comes with the First(), Last() and FindBy() methods. Massive is based around a dynamic object called DynamicModel and doesn't define any of the above method; it handles them through a TryInvokeMethod() implementation overriden from DynamicObject instead: public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result) { } I'm at a loss on how to "interface" those methods in my ISession. How could my ISession provide support for First(), Last() and FindBy()? Put it another way, how can I use all of Massive's capabilities and still be able to decouple my classes from data access?

• OpenID and Authlogic - login and password?

  - by skrat

  How can I get rid of validation messages telling me that: Login is too short (minimum is 3 characters) Login should use only letters, numbers, spaces, and .-_@ please. Password is too short (minimum is 4 characters) Password confirmation is too short (minimum is 4 characters) this happens even before map_openid_registration is called, thus not giving me any chance to fill login with something from returned registration Hash. I would like to have OpenID auto-registration (on login) without requiring user to supply login/password. I also won't make this fields "not required" or "not validated", since I still need them with old school login/password registration. Thank you

• Select highest rated, oldest track

  I have several tables: CREATE TABLE [dbo].[Tracks]( [Id] [uniqueidentifier] NOT NULL, [Artist_Id] [uniqueidentifier] NOT NULL, [Album_Id] [uniqueidentifier] NOT NULL, [Title] [nvarchar](255) NOT NULL, [Length] [int] NOT NULL, CONSTRAINT [PK_Tracks_1] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[TrackHistory]( [Id] [int] IDENTITY(1,1) NOT NULL, [Track_Id] [uniqueidentifier] NOT NULL, [Datetime] [datetime] NOT NULL, CONSTRAINT [PK_TrackHistory] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] INSERT INTO [cooltunes].[dbo].[TrackHistory] ([Track_Id] ,[Datetime]) VALUES ("335294B0-735E-4E2C-8389-8326B17CE813" ,GETDATE()) CREATE TABLE [dbo].[Ratings]( [Id] [int] IDENTITY(1,1) NOT NULL, [Track_Id] [uniqueidentifier] NOT NULL, [User_Id] [uniqueidentifier] NOT NULL, [Rating] [tinyint] NOT NULL, CONSTRAINT [PK_Ratings] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] INSERT INTO [cooltunes].[dbo].[Ratings] ([Track_Id] ,[User_Id] ,[Rating]) VALUES ("335294B0-735E-4E2C-8389-8326B17CE813" ,"C7D62450-8BE6-40F6-80F1-A539DA301772" ,1) Users User_Id|Guid Other fields Links between the tables are pretty obvious. TrackHistory has each track added to it as a row whenever it is played ie. a track will appear in there many times. Ratings value will either be 1 or -1. What I'm trying to do is select the Track with the highest rating, that is more than 2 hours old, and if there is a duplicate rating for a track (ie a track receives 6 +1 ratings and 1 - rating, giving that track a total rating of 5, another track also has a total rating of 5), the track that was last played the longest ago should be returned. (If all tracks have been played within the last 2 hours, no rows should be returned) I'm getting somewhere doing each part individually using the link above, SUM(Value) and GROUP BY Track_Id, but I'm having trouble putting it all together. Hopefully someone with a bit more (MS)SQL knowledge will be able to help me. Many thanks!

• Ways to gain a deeper understanding of programming concepts?

  - by MrPlow

  I'm a marketer and have been messing around in PHP/MySQL for years. Recently (the last several months) I've been making my own scripts/programs in Python and I've really enjoyed the whole problem solving process. I've read(skimmed) some books and understand the basics of OOP, polymorphism, etc.. I have a general interest in AI and Natural Language in particular but it seems these things require a masters in Computer Science. My knowledge of math is poor. The last class I took was calculus, and I've forgotten the majority of it. Basically I'm looking for things to learn that will help me think in a more analytic way, and maybe see solutions where I didn't before. Improving my ability to program in Python would be nice too. I don't need to learn a specific language or something for employment, just enjoyment. Although my work often involves web development so some utility would be nice. I don't like learning concepts by just reading them. I need to apply them, even if the examples are contrived. A recommendation of a couple good books or other resources would be nice. :) Apologies if this is too vague/misplaced...

• Django aggregate query generating SQL error

  - by meepmeep

  I'm using Django 1.1.1 on a SQL Server 2005 db using the latest sqlserver_ado library. models.py includes: class Project(models.Model): name = models.CharField(max_length=50) class Thing(models.Model): project = models.ForeignKey(Project) reference = models.CharField(max_length=50) class ThingMonth(models.Model): thing = models.ForeignKey(Thing) timestamp = models.DateTimeField() ThingMonthValue = models.FloatField() class Meta: db_table = u'ThingMonthSummary' In a view, I have retrieved a queryset called 'things' which contains 25 Things: things = Thing.objects.select_related().filter(project=1).order_by('reference') I then want to do an aggregate query to get the average ThingMonthValue for the first 20 of those Things for a certain period, and the same value for the last 5. For the first 20 I do: averageThingMonthValue = ThingMonth.objects.filter(turbine__in=things[:20],timestamp__range="2009-01-01 00:00","2010-03-00:00")).aggregate(Avg('ThingMonthValue'))['ThingMonthValue__avg'] This works fine, and returns the desired value. For the last 5 I do: averageThingMonthValue = ThingMonth.objects.filter(turbine__in=things[20:],timestamp__range="2009-01-01 00:00","2010-03-00:00")).aggregate(Avg('ThingMonthValue'))['ThingMonthValue__avg'] But for this I get an SQL error: 'Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.' The SQL query being used by django reads: SELECT AVG([ThingMonthSummary].[ThingMonthValue]) AS [ThingMonthValue__avg] FROM [ThingMonthSummary] WHERE ([ThingMonthSummary].[thing_id] IN (SELECT _row_num, [id] FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY [AAAA].[id] ASC) as _row_num, [AAAA].[id] FROM ( SELECT U0.[id] FROM [Thing] U0 WHERE U0.[project_id] = 1 ) AS [AAAA]) as QQQ where 20 < _row_num) AND [ThingMonthSummary].[timestamp] BETWEEN '01/01/09 00:00:00' and '03/01/10 00:00:00') Any idea why it works for one slice of the Things and not the second? I've checked and the two slices do contain the desired Things correctly.

• Unique identifiers for users

  - by Christopher McCann

  If I have a table of a hundred users normally I would just set up an auto-increment userID column as the primary key. But if suddenly we have a million users or 5 million users then that becomes really difficult because I would want to start becoming more distributed in which case an auto-increment primary key would be useless as each node would be creating the same primary keys. Is the solution to this to use natural primary keys? I am having a real hard time thinking of a natural primary key for this bunch of users. The problem is they are all young people so they do not have national insurance numbers or any other unique identifier I can think of. I could create a multi-column primary key but there is still a chance, however miniscule of duplicates occurring. Does anyone know of a solution? Thanks

• C++ LPTSTR to int (but memory overwrite problem using atoi)

  - by Dexter

  I have the following code, m_edit is a MFC CEdit (I know I would never use MFC but project demanded it). It's a simple loop, that gets the text from a text edit, converts it to integer after getting the first line, then stores it in m_y vector. LPTSTR szTemp; vector<int> m_y; for(int i = 0; i < m_edit->GetLineCount(); i++){ szTemp = s_y.GetBuffer(0); m_edit->GetLine(i, szTemp); // get line text store in szTemp y = atoi(szTemp); m_y.push_back(y); szTemp = ""; y = 0; } IMPORTANT EXAMPLE: So let's say the CEdit has 6 numbers: 0 5 2 5 18 6 If you use Visual Studio's debugger you will notice an anomaly!! Here's what it shows: y = 0 y = 5 y = 2 y = 5 y = 18 y = 68 Do you see that? szTemp when inserted into atoi, it returns the number 6, but concatenates the 2nd digit of the last number!!! This is why I did szTemp = "";, but the problem persists. Also, let's say the last number was 17 (not 18), then this time debugger would say y = 67, so it is definitely this problem. However, Visual Studio debugger, when you hover over szTemp during this iteration, it says '6' <--- not '68' inside szTemp. So somehow atoi is ruining it. Am I suppose to concatenate a \0 into szTemp before putting it into atoi? How do I solve this easily?

• Smooth mousover images inside scaled Flex App?

  - by Josh Handel

  I have a flex app I am scaling using systemManager.stage.scaleMode=StageScaleMode.NO_BORDER; for the most part it works well except for my bitmap data (mostly png's from the designers). I can set the mx:image tags to smoothBitmapContent=true and that works great for everything except my mouseover objects. When I do a mouseover, the source is being changed from one embedded image to another embedded image. I have tried several (many) online "smoothimage" classes, and tried to write my own, I have tried to reset smoothBitmapContent every chance I get but still no dice. It seems to mee that because I am scaling at the app level, that the flopped out bitmap is not getting smoothed when it renders. Does anyone have any suggestions on how to keep things smooth (perhaps there is a flag to tell Flex to smooth stuff when it scales it?). Thanks Josh

• Inside what the TexBox value is posted back? ViewState or post back data?

  - by burak ozdogan

  In one article I was reading on ViewState, I saw a sentence saying that I should not fall into a mistake to believe that the value of a TextBox is stored in ViewState; it is stored in PostBack data. From here what I understand is when I post back a web form, the input controls values are stored in HTTP Request body. Not in the Viewstate. But as far as I know ViewState values are stored in an hidden field called __VIEWSTATE anyway. Then does it mean that __VIEVSTATE value is not posted in HTTP POST Request body as a postback data? Sounds nonesense to me. In another words, basically if I say the ViewState mechanism for such scenerio works like this, am I seeing it right or skipping something: You enter a value on an empty TextBox and submit the page The value of text box is posted back inside POST HTTP Request body. Nothing inside __VIEWSTATE at this point from the TextBox On the server side, the TextBox is created with the default value on OnInit method of the page The TrackChange property of ViewState is set to true. The posted back data of TextBox is loaded. Because it is different than the TextBox defalut value(because the user entered something), the ViewState of this text box is marked as DIRTY. The new value of the textbox is written into __VIEWSTATE hidden field From now on __VIEWSTATE hiddenfeild contains the last given value of the TextBox The page is sent to the user's browser having the __VIEWSTATE hidden field. But this time containing the last value entered by user which will be ready to be rendered Thanks guys! burak ozdogan

• How do I get 3 lines of text from a paragraph in C#

  - by Keltex

  I'm trying to create an "snippet" from a paragraph. I have a long paragraph of text with a word hilighted in the middle. I want to get the line containing the word before that line and the line after that line. I have the following piece of information: The text (in a string) The lines are deliminated by a NEWLINE character \n I have the index into the string of the text I want to hilight A couple other criteria: If my word falls on first line of the paragraph, it should show the 1st 3 lines If my word falls on the last line of the paragraph, it should show the last 3 lines Should show the entire paragraph in the degenative cases (the paragraph only has 1 or 2 lines) Here's an example: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph Example, if my index points to BIRD, it should show lines 1, 2, & 3 as one complete string like this: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph If my index points to DOG, it should show lines 3, 4, & 5 as one complete string like this: This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph etc. Anybody want to help tackle this?

• How do you send email invites to people who have been invited by users of your website?

  - by Arpit Rai

  We've developed a web application where people can sign-up on our website to make use of our service. We have a functionality that allows users to send invites to their friends by looking up their contacts on Gmail, Yahoo Mail etc. My question is - do we have to use a 3rd party email management software like a MailChimp or SendGrid to send such emails or should we send them directly? If we send the emails directly and if the recipients start marking those emails as spam, isn't there a very high chance that we might get banned by Gmail, Yahoo etc.?

• Deselecting a form input and waiting for a function before submitting

  - by blcArmadillo

  I have a form with an input field where a user enters a unique identifier. I then have some jQuery code that upon the user moving away from the input field (blur) goes out and fetches details about the part and populates some fields on the page. The problem is if the user clicks the submit button before moving out of the input field the jQuery code never has a chance to load in the data and populate the necessary fields. Whats the best way to go about doing this? I thought about maybe setting the focus to body and then having an infinite loop that keeps checking the page until all fields that should be filled in have been filled in but I feel like some sort of event based solution would be better than unpredictable infinite loops. Any ideas?

Is there a way to permanently embed a function in my html template page that retrieves the latest few posts everytime an article is displayed on the template page? the code: <?php require('/the/path/to/your/wp-blog-header.php'); ?> <?php $posts = get_posts('numberposts=10&order=ASC&orderby=post_title'); foreach ($posts as $post) : start_wp(); ?> <?php the_title(); ?> <?php the_excerpt(); ?> <?php endforeach; ?>

• Visual Studio 2008 project file does not load because of an unexpected encoding change.

  - by Xenan

  In our team we have a database project in visual Studio 2008 which is under source control by Team Foundation Server. Every two weeks or so, after one co-worker checks in, the project file won't load on the other developers machines. The error message is: The project file could not be loaded. Data at the root level is invalid. Line 1, position 1. When I look at the project file in Notepad++, the file looks like this: ??<NUL?NULxNULmNULlNUL NULvNULeNULrNULsNULiNULoNULnNUL ... and so on (you can see <?xml version in this) whereas an normal project file looks like: <?xml version="1.0" encoding="utf-16"?> ... So probably something is wrong with the encoding of the file. This is a problem for us because it turns out to be impossible to get the file encoding correct again. The 'solution' is to throw away the project file an get the last know working version from source control. According to the file, the encoding should be UTF-16. According to Notepad++, the corrupted file is actually UTF-8. My questions are: Why is Visual Studio messing up the encoding of the project file, apparently at random times and at random machines? What should we do to prevent this? When it has happened, is there a possibility to restore the current file in the correct encoding instead of pulling an older version from source control? As a last note: the problem is with one single project file, all other project files don't expose this problem.

• Django: Overriding the save() method: how do I call the delete() method of a child class

  - by Patti

  The setup = I have this class, Transcript: class Transcript(models.Model): body = models.TextField('Body') doPagination = models.BooleanField('Paginate') numPages = models.PositiveIntegerField('Number of Pages') and this class, TranscriptPages(models.Model): class TranscriptPages(models.Model): transcript = models.ForeignKey(Transcript) order = models.PositiveIntegerField('Order') content = models.TextField('Page Content', null=True, blank=True) The Admin behavior I’m trying to create is to let a user populate Transcript.body with the entire contents of a long document and, if they set Transcript.doPagination = True and save the Transcript admin, I will automatically split the body into n Transcript pages. In the admin, TranscriptPages is a StackedInline of the Transcript Admin. To do this I’m overridding Transcript’s save method: def save(self): if self.doPagination: #do stuff super(Transcript, self).save() else: super(Transcript, self).save() The problem = When Transcript.doPagination is True, I want to manually delete all of the TranscriptPages that reference this Transcript so I can then create them again from scratch. So, I thought this would work: #do stuff TranscriptPages.objects.filter(transcript__id=self.id).delete() super(Transcript, self).save() but when I try I get this error: Exception Type: ValidationError Exception Value: [u'Select a valid choice. That choice is not one of the available choices.'] ... and this is the last thing in the stack trace before the exception is raised: .../django/forms/models.py in save_existing_objects pk_value = form.fields[pk_name].clean(raw_pk_value) Other attempts to fix: t = self.transcriptpages_set.all().delete() (where self = Transcript from the save() method) looping over t (above) and deleting each item individually making a post_save signal on TranscriptPages that calls the delete method Any ideas? How does the Admin do it? UPDATE: Every once in a while as I'm playing around with the code I can get a different error (below), but then it just goes away and I can't replicate it again... until the next random time. Exception Type: MultiValueDictKeyError Exception Value: "Key 'transcriptpages_set-0-id' not found in " Exception Location: .../django/utils/datastructures.py in getitem, line 203 and the last lines from the trace: .../django/forms/models.py in _construct_form form = super(BaseInlineFormSet, self)._construct_form(i, **kwargs) .../django/utils/datastructures.py in getitem pk = self.data[pk_key]

• Obtaining Current Fiscal Year from Hierarchy with MDX

  - by Robert Iver

  I'm building a report in Reporting Services 2005 based on a SSAS 2005 cube. The basic idea of the report is that they want to see sales for this fiscal year to date vs. last year sales year to date. It sounds simple, but being that this is my first "real" report based on SSAS, I'm having a hell of a time. First, how would one calculate the current fiscal year, quarter, or month. I have a Fiscal Date Hierarchy with all that information in it, but I can't figure out how to say: "Based on today's date, find the current fiscal year, quarter, and month." My second, but slightly smaller problem, is getting last years sales vs. this years sales. I have seen MANY examples on how to do this, but they all assume that you select the date manually. Since this is a report and will run pretty much on it's own, I need a way to insert the "current" fiscal year, quarter, and month into the PERIODSTODATE or PARALLELPERIOD functions to get what I want. So, I'm begging for your help on this one. I have to have this report done by tomorrow monring and I'm beginning to freak out a bit. Thanks in advance.

• git doesn't show where code was removed.

  - by Andrew Myers

  So I was tasked at replacing some dummy code that our project requires for historical compatibility reasons but has mysteriously dropped out sometime since the last release. Since disappearing code makes me nervous about what else might have gone missing but un-noticed I've been digging through the logs trying to find in what commit this handful of lines was removed. I've tried a number of things including "git log -S'add-visit-resource-pcf'", git blame, and even git bisect with a script that simply checks for the existence of the line but have been unable to pinpoint exactly where these lines were removed. I find this very perplexing, particularly since the last log entry (obtained by the above command) before my re-introduction of this code was someone else adding the code as well. commit 0b0556fa87ff80d0ffcc2b451cca1581289bbc3c Author: Andrew Date: Thu May 13 10:55:32 2010 -0400 Re-introduced add-visit-resource-pcf, see PR-65034. diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index f8e692d..a6f8d38 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -115,6 +115,7 @@ #:add-to-current-resource-pcf #:add-user-package-nickname #:add-value-criteria + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types commit 9fb10e25572c537076284a248be1fbf757c1a6e1 Author: Bob Date: Sun Jan 17 18:35:16 2010 -0500 update-defpackage for Spike 33.1 Delivery diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index 983666d..47f1a9a 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -118,6 +118,7 @@ #:add-user-package-nickname #:add-value-criteria #:add-vars-from-proposal + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types This is for one of our package definition files, but the relevant source file reflects something similar.
