  • Action Mailer: How do I render dynamic data in an email body that is stored in the database?

    - by Brandon Toone
    I have Action Mailer setup to render an email using the body attribute of my Email model (in the database). I want to be able to use erb in the body but I can't figure out how to get it to render in the sent email message. I'm able to get the body as a string with this code # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # pulls the email body and passes a string to the template views/user_mailer/customer_email.text.html.erb body :msg => email.body end I came across this article http://rails-nutshell.labs.oreilly.com/ch05.html which says I can use render but I'm only able to get render :text to work and not render :inline # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # body :msg => email.body body :msg => (render :text => "Thanks for your order") # renders text and passes as a variable to the template # body :msg => (render :inline => "We shipped <%= Time.now %>") # throws a NoMethodError end

  • Is there a way to easily convert a series of tarballs of a source tree into a git repository?

    - by Hotei
    I'm new to git and I have a moderately large number of weekly tarballs from a long running project. Each tarball has on average a few hundred files in it. I'm looking for a git strategy that will allow me to add the expanded contents of each tarball to a new git repository, starting from version 1.001 and going through version 1.650. As of this stage of the project 99.5% of tarball(n) is just a copy of version(n-1) - in other words, a perfect candidate for git. The desired end result is to have only the master branch remaining at the end of the process. I think I know git well enough to do this "by hand". As I understand it there is no possibility of a merge conflict since there will be no opportunity to change the master before the next version is added and committed. A shell script is my first guess, but I'm not sure how well bash will like it when git checkout branch_n gets processed while bash is executing in branch_n-1. For the purposes of this project the host environment is Ubuntu 10.4, resources available are 8 Gig RAM, 500 Gig Disk space free and 4 CPU processor at 3.ghz . I don't need someone else to solve the problem but I could use a nudge in the right direction as to how a git expert would approach it. Any advice from someone who's "been there done that" would be appreciated. Hotei PS: I have looked at site's suggested "related questions" and found nothing relevant.

  • Conventions for the behavior of double or triple "click to select text" features?

    - by John Sullivan
    Almost any mature program that involves text implements "double click to select the word" and, in some cases, "triple click to select additional stuff like an entire line" as a feature. I find these features useful but they are often inconsistent between programs. Example - some programs' double clicks do not select the ending space after a word, but most do. Some recognize the - character as the end of a word, others do not. SO likes to select the entire paragraph as I write this post when I triple click it, VS web developer 2005 has no triple click support, and ultra-edit 32 will select one line upon triple clicking. We could come up with innumerable inconsistencies about how double and triple click pattern matching is implemented across programs. I am concerned about how to implement this behavior in my program if nobody else has achieved a convention about how the pattern matching should work. My question is, does a convention (conventions? maybe an MS or Linux convention?) exist that dictates how these features are supposed to behave to the end user? What, if any, are they?

  • What's the best NAME for "quick" Category you add to a file?

    - by Joe Blow
    So the other day I was sick of typing out repetetive addTarget:action:forControlEvents:s, and macros are only entertaining for so long, so I did this: @implementation UIControl (xx) -(void)addTarget:(id)target action:(SEL)action { [self addTarget:target action:action forControlEvents:UIControlEventTouchUpInside]; } @end *and simply added it at the top of the .m file in question. Works great of course, but notice the "xx".* What's the best thing to NAME a "quick" Category like this? Annoyingly, it appears you can not leave the xx blank - it would then become an "Extension" (which, incidentally, I don't understand at all). I was thinking maybe: a single underscore the name of the class again identically "quick" perhaps the name of the class in this file (as in "quick extra routines for UIControl in CherryBomb") - so it would be UIControl(CherryBomb), ie, remind you that these extra routines are handy for CherryBomb "x" your or your company's initials (use the same "quick" Category name everywhere) "ThisTextNeverUsedAnywhere" By the way, I've been assuming that Categories only happen in the files that see them (CherryBomb.m in the example) - they do not from then on apply app-wide. ie they only apply where you include the header file (UIControl+NattyStuff) or in the "quick" case only in the file to which one adds the text. (By the way ... it appears you do not actually need to include an interface for such a Category, i.e. you can omit... //you can actually get away without these lines... //#import <UIKit/UIControl.h> //@interface UIControl (x) //-(void)addTarget:(id)target action:(SEL)action; //@end ... that part and it works fine.) For people who love Categories, and who doesn't, what's the answer to this troubling question? What should you name a "quick" Category where the name is never going to be referenced again and is irrelevant? Is "_" a solution?

  • Return if remote stored procedure fails

    - by njk
    I am in the process of creating a stored procedure. This stored procedure runs local as well as external stored procedures. For simplicity, I'll call the local server [LOCAL] and the remote server [REMOTE]. USE [LOCAL] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[monthlyRollUp] AS SET NOCOUNT, XACT_ABORT ON BEGIN TRY EXEC [REOMTE].[DB].[table].[sp] --This transaction should only begin if the remote procedure does not fail BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp1] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp2] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp3] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp4] COMMIT END TRY BEGIN CATCH -- Insert error into log table INSERT INTO [dbo].[log_table] (stamp, errorNumber, errorSeverity, errorState, errorProcedure, errorLine, errorMessage) SELECT GETDATE(), ERROR_NUMBER(), ERROR_SEVERITY(), ERROR_STATE(), ERROR_PROCEDURE(), ERROR_LINE(), ERROR_MESSAGE() END CATCH GO When using a transaction on the remote procedure, it throws this error: OLE DB provider ... returned message "The partner transaction manager has disabled its support for remote/network transactions.". I get that I'm unable to run a transaction locally for a remote procedure. How can I ensure that the this procedure will exit and rollback if any part of the procedure fails?

  • Apply a Quartz filter while saving PDF under Mac OS X 10.6.3

    - by olpa
    Using Mac OS X API, I'm trying to save a PDF file with a Quartz filter applied, just like it is possible from the "Save As" dialog in the Preview application. So far I've written the following code (using Python and pyObjC, but it isn't important for me): -- filter-pdf.py: begin from Foundation import * from Quartz import * import objc page_rect = CGRectMake (0, 0, 612, 792) fdict = NSDictionary.dictionaryWithContentsOfFile_("/System/Library/Filters/Blue \ Tone.qfilter") in_pdf = CGPDFDocumentCreateWithProvider(CGDataProviderCreateWithFilename ("test .pdf")) url = CFURLCreateWithFileSystemPath(None, "test_out.pdf", kCFURLPOSIXPathStyle, False) c = CGPDFContextCreateWithURL(url, page_rect, fdict) np = CGPDFDocumentGetNumberOfPages(in_pdf) for ip in range (1, np+1): page = CGPDFDocumentGetPage(in_pdf, ip) r = CGPDFPageGetBoxRect(page, kCGPDFMediaBox) CGContextBeginPage(c, r) CGContextDrawPDFPage(c, page) CGContextEndPage(c) -- filter-pdf.py: end Unfortunalte, the filter "Blue Tone" isn't applied, the output PDF looks exactly as the input PDF. Question: what I missed? How to apply a filter? Well, the documentation doesn't promise that such way of creating and using "fdict" should cause that the filter is applied. But I just rewritten (as far as I can) sample code /Developer/Examples/Quartz/Python/filter-pdf.py, which was distributed with older versions of Mac (meanwhile, this code doesn't work too): ----- filter-pdf-old.py: begin from CoreGraphics import * import sys, os, math, getopt, string def usage (): print ''' usage: python filter-pdf.py FILTER INPUT-PDF OUTPUT-PDF Apply a ColorSync Filter to a PDF document. ''' def main (): page_rect = CGRectMake (0, 0, 612, 792) try: opts,args = getopt.getopt (sys.argv[1:], '', []) except getopt.GetoptError: usage () sys.exit (1) if len (args) != 3: usage () sys.exit (1) filter = CGContextFilterCreateDictionary (args[0]) if not filter: print 'Unable to create context filter' sys.exit (1) pdf = CGPDFDocumentCreateWithProvider (CGDataProviderCreateWithFilename (args[1])) if not pdf: print 'Unable to open input file' sys.exit (1) c = CGPDFContextCreateWithFilename (args[2], page_rect, filter) if not c: print 'Unable to create output context' sys.exit (1) for p in range (1, pdf.getNumberOfPages () + 1): #r = pdf.getMediaBox (p) r = pdf.getPage(p).getBoxRect(p) c.beginPage (r) c.drawPDFDocument (r, pdf, p) c.endPage () c.finish () if __name__ == '__main__': main () ----- filter-pdf-old.py: end

  • Python subprocess: 64 bit windows server PIPE doesn't exist :(

    - by Spaceman1861
    I have a GUI that launches selected python scripts and runs it in cmd next to the gui window. I am able to get my launcher to work on my (windows xp 32 bit) laptop but when I upload it to the server(64bit windows iss7) I am running into some issues. The script runs, to my knowledge but spits back no information into the cmd window. My script is a bit of a Frankenstein that I have hacked and slashed together to get it to work I am fairly certain that this is a very bad example of the subprocess module. Just wondering if i could get a hand :). My question is how do i have to alter my code to work on a 64bit windows server. :) from Tkinter import * import pickle,subprocess,errno,time,sys,os PIPE = subprocess.PIPE if subprocess.mswindows: from win32file import ReadFile, WriteFile from win32pipe import PeekNamedPipe import msvcrt else: import select import fcntl def recv_some(p, t=.1, e=1, tr=5, stderr=0): if tr < 1: tr = 1 x = time.time()+t y = [] r = '' pr = p.recv if stderr: pr = p.recv_err while time.time() < x or r: r = pr() if r is None: if e: raise Exception(message) else: break elif r: y.append(r) else: time.sleep(max((x-time.time())/tr, 0)) return ''.join(y) def send_all(p, data): while len(data): sent = p.send(data) if sent is None: raise Exception(message) data = buffer(data, sent) The code above isn't mine def Run(): print filebox.get(0) location = filebox.get(0) location = location.__str__().replace(listbox.get(ANCHOR).__str__(),"") theTime = time.asctime(time.localtime(time.time())) lastbox.delete(0, END) lastbox.insert(END,theTime) for line in CookieCont: if listbox.get(ANCHOR) in line and len(line) > 4: line[4] = theTime else: "Fill In the rip Details to record the time" if __name__ == '__main__': if sys.platform == 'win32' or sys.platform == 'win64': shell, commands, tail = ('cmd', ('cd "'+location+'"',listbox.get(ANCHOR).__str__()), '\r\n') else: return "Please use contact admin" a = Popen(shell, stdin=PIPE, stdout=PIPE) print recv_some(a) for cmd in commands: send_all(a, cmd + tail) print recv_some(a) send_all(a, 'exit' + tail) print recv_some(a, e=0) The Code above is mine :)

  • Various asp controls in a ASP.NET page

    - by Filipe Costa
    Hello. I am creating a products page, where the user selects an option in a radiobuttonlist for example, and then a control with the various options of that product appears in a placeholder or in a div when on of the radiobuttons is selected. At the moment this is the code: aspx: <form runat="server"> <asp:CheckBoxList ID="Lentes" runat="server" OnClick="EscolheLentes"> <asp:ListItem Value="LU"> Lentes Unifocais </asp:ListItem> <asp:ListItem Value="LP"> Lentes Progressivas </asp:ListItem> </asp:CheckBoxList> <asp:PlaceHolder runat="server" ID="PHLentes"></asp:PlaceHolder> </form> aspx.vb: Protected Sub EscolheLentes() Dim ControlLente As Control If (Me.Lentes.Items.FindByValue("LU").Selected) Then ControlLente = LoadControl("LentesUnifocais.ascx") ElseIf (Me.Lentes.Items.FindByValue("LP").Selected) Then ControlLente = LoadControl("LentesProgressivas.ascx") End If Me.PHLentes.Controls.Add(ControlLente) End Sub Need to use some ajax to load the control right? Am i going in the right direction? Thanks.

  • Why would the value of the Session object go away?

    - by Michael
    In ASP.NET/VB.NET 2005 I've created a small web app with two forms. In Default there is a button and a text box and a link. When you press the button whatever is in the text box is put into the Session. Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click System.Web.HttpContext.Current.Session("mykey") = Me.TextBox1.Text End Sub When you press the link it's NavigateURL property is "~/Retrieve.aspx" On the Retrieve page it pulls the information out of the Session (that is, whatever you typed in the text box). Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim myValue As String = CType(System.Web.HttpContext.Current.Session("mykey"), String) Response.Write(myValue) End Sub Now it works on my machine and when deployed to the production web-site server if I run the browser remotely there it works fine - What you type on the first page appears on the second page. But when I run it from my machine to the production web server the second page is always blank. Why? It doesnt seem like a timeout issue - brand new web.config taking the defaults. Any pointers would be greatly appreciated! Thanks!

  • visusal studio embedded crystal report keeps prompting database login?

  • C#: Take Out Image Portion of JPEG to Backup Metadata?

    - by Carlo Mendoza
    This will be a little backwards from the typical approach. I've used ExifTool for metadata manipulation before, but I really want to keep the best metadata backup I can before I make anything permanent. What I want to do is remove the compressed image portion of a JPEG file to leave everything else intact. That's backing up EXIF, Makernotes, IPTC, XMP, etc whether at the beginning or end of the file. What I've tried so far is to strip all metadata from a copy of the original JPEG, and use it as a basis of what bytes will be taken out of the original. After looking at the raw data, it doesn't seem like the stripped copy is contiguous in the original copy. There may be some header information still remaining in the stripped version. I don't really know. Not a good way to do it, I suppose. Are there any markers that will absolutely tell me where the compressed JPEG image data starts and ends? I understand that JPEG files have 0xFFD8 and 0xFFD9 to mark the start and end of the image, but have come to find out that metadata is actually between those markers. I'm using C#. Thank you.

  • Shall this Regex do what I expect from it, that is, matching against "A1:B10,C3,D4:E1000"?

    - by Will Marcouiller
    I'm currently writing a library where I wish to allow the user to be able to specify spreadsheet cell(s) under four possible alternatives: A single cell: "A1"; Multiple contiguous cells: "A1:B10" Multiple separate cells: "A1,B6,I60,AA2" A mix of 2 and 3: "B2:B12,C13:C18,D4,E11000" Then, to validate whether the input respects these formats, I intended to use a regular expression to match against. I have consulted this article on Wikipedia: Regular Expression (Wikipedia) And I also found this related SO question: regex matching alpha character followed by 4 alphanumerics. Based on the information provided within the above-linked articles, I would try with this Regex: Default Readonly Property Cells(ByVal cellsAddresses As String) As ReadOnlyDictionary(Of String, ICell) Get Dim validAddresses As Regex = New Regex("A-Za-z0-9:,A-Za-z0-9") If (Not validAddresses.IsMatch(cellsAddresses)) then _ Throw New FormatException("cellsAddresses") // Proceed with getting the cells from the Interop here... End Get End Property Questions 1. Is my regular expression correct? If not, please help me understand what expression I could use. 2. What exception is more likely to be the more meaningful between a FormatException and an InvalidExpressionException? I hesitate here, since it is related to the format under which the property expect the cells to be input, aside, I'm using an (regular) expression to match against. Thank you kindly for your help and support! =)

  • Rails - strip xml import from whitespace and line break

    - by val_to_many
    Hey folks, I am stuck with something quite simple but really annoying: I have an xml file with one node, where the content includes line breaks and whitspaces. Sadly I can't change the xml. <?xml version="1.0" encoding="utf-8" ?> <ProductFeed> ACME Ltd. Fooproduct Foo Root :: Bar Category I get to the node and can read from it without trouble: url = "http://feeds.somefeed/feed.xml.gz" @source = open((url), :http_basic_authentication=>["USER", "PW"]) @gz = Zlib::GzipReader.new(@source) @result = @gz.read @doc = Nokogiri::XML(@result) @doc.xpath("/ProductFeed/Vendors/Vendor").each do |manuf| vendor = manuf.css("Name").first.text manuf.xpath("//child::Product").each do |product| product_name = product.css("Name").text foocat = product.css("Category").text puts "#{vendor} ---- #{product_name} ---- #{foocat} " end end This results in: ACME Ltd. ---- Fooproduct ---- Foo Root :: Bar Category Obviously there are line breaks and tab stops or spaces in the string returned by product.css("Category").text. Does anyone know how to strip the result from linebreaks and taps or spaces right here? Alternatively I could do that in the next step, where I do a find on 'foocat' like barcat = Category.find_by_foocat(foocat) Thanks for helping! Val

Linking tool main ... ./obj/main.o:(.data.rel+0x0): undefined reference to `__objc_class_name_Fraction' So in both cases compiler gets stuck at undefined reference to `__objc_class_name_Fraction' Do you have and idea how to resolve this issue?

  • Join two tables with same # of row but sorted for NULL

    - by VISQL
    I need to join two tables with the same number of rows. Each table has 1 column. There is NO CONNECTING COLUMN to reference for a join. I need to join them side by side because each table was sorted separately so that numeric values are at the top in descinding order. The Table Earners has income values from say 200K down to 0. I cannot just select using 2 cases, because then I will have my first row with Incomes above 100K, but the first 20 or so entries in the second row are NULL. I want the second row to also be sorted descending. I looked up using ORDER BY within CASE but there is no such thing. I have tried to read about row_number() but none of the examples seem to match or make sense. drop table #20plus select case when Income >= 20000 AND Income < 100000 then Income end as 'mula' into #20plus from Earners order by mula desc drop table #100plus select case when Income >= 100000 then Income end as 'dinero' into #100plus from Earners order by dinero desc Select A.dinero, B.mula FROM #100plus as A JOIN #20plus as B ON A.????? = B.????? Since both A and B are sorted descending, moving all NULL to the bottom, what can I reference to join the two tables? Previous output using one SELECT statement with 2 CASE statements dinero mula 2.12688e+007 NULL 1.80031e+007 NULL 1.92415e+006 NULL … … NULL 93530.7 NULL 91000 NULL 84500 Desired output using one SELECT statement after creating two temp TABLES dinero mula 2.12688e+007 93530.7 1.80031e+007 91000 1.92415e+006 84500 … 82500 NULL 82000 NULL … NULL NULL This is Microsoft SQL Server 2008. I'm super new to this, so please give an answer as clear and simplified as possible. Thank you.

  • Rails3 renders a js.erb template with a text/html content-type instead of text/javascript

    - by Yannis
    Hi, I'm building a new app with 3.0.0.beta3. I simply try to render a js.erb template to an Ajax request for the following action (in publications_controller.rb): def get_pubmed_data entry = Bio::PubMed.query(params[:pmid])# searches PubMed and get entry @publication = Bio::MEDLINE.new(entry) # creates Bio::MEDLINE object from entry text flash[:warning] = "No publication found."if @publication.title.blank? and @publication.authors.blank? and @publication.journal.blank? respond_to do |format| format.js end end Currently, my get_pubmed_data.js.erb template is simply alert('<%= @publication.title %>') The server is responding with the following alert('Evidence for a herpes simplex virus-specific factor controlling the transcription of deoxypyrimidine kinase.') which is perfectly fine except that nothing happen in the browser, probably because the content-type of the response is 'text/html' instead of 'text/javascript' as shown by the response header partially reproduced here: Status 200 Keep-Alive timeout=5, max=100 Connection Keep-Alive Transfer-Encoding chunked Content-Type text/html; charset=utf-8 Is this a bug or am I missing something? Thanks for your help!

  • Form With Quantity doesn't seem to submit

    - by Karl Entwistle
    Hey guys, I've been trying to understand the documentation and find an example, but I'm at a loss. This is just a submit form within the cart for updating the quantity. However, the updated quantity is not getting saved to the database -- it always makes the quantity 0. Please help. Form <% for line_item in @cart.line_items %> <% form_for :lineitems, :url => {:controller => "line_items", :action => "cart_update", :id => "#{line_item.product_id}"} do |l| %> <%= l.text_field :quantity, :size => '3', :value => line_item.quantity %> <%= l.submit 'cart_update' %> <% end %> Route map.connect 'line_item_update', :controller => 'line_items', :action => 'cart_update' Controller def cart_update @product = Product.find(params[:id]) item = LineItem.find_or_create_by_cart_id(:cart_id => current_cart.id, :product_id => @product.id, :quantity => 0, :unit_price => @product.price) item.quantity = (params[:quantity]).to_i item.save redirect_to :controller => 'products' end

  • Add dynamic charts using ASP.NET CHART CONTROL, c#

    - by dhareni
    I wanted to add dynamic charts in the webpage. It goes like this... I get the start and end date from user and draw separate charts for each date bewteen the start and end date. I get the data from sql database and bind it with the chart like this: SqlConnection UsageLogConn = new SqlConnection(ConfigurationManager.ConnectionStrings["UsageConn"].ConnectionString); UsageLogConn.Open();//open connection string sql = "SELECT v.interval,dateadd(mi,(v.interval-1)*2,'" + startdate + " 00:00:00') as 'intervaltime',COUNT(Datediff(minute,'" + startdate + " 00:00:00',d.DateTime)/2) AS Total FROM usage_internet_intervals v left outer join (select * from Usage_Internet where " + name + " LIKE ('%" + value + "%') and DateTime BETWEEN '" + startdate + " 00:00:00' AND '" + enddate + " 23:59:59') d on v.interval = Datediff(minute,'" + startdate + " 00:00:00',d.DateTime)/2 GROUP BY v.interval,Datediff(minute,'" + startdate + " 00:00:00',d.DateTime)/2 ORDER BY Interval"; SqlCommand cmd = new SqlCommand(sql, UsageLogConn); SqlDataAdapter mySQLadapter = new SqlDataAdapter(cmd); Chart1.DataSource = cmd; // set series members names for the X and Y values Chart1.Series["Series 1"].XValueMember = "intervaltime"; Chart1.Series["Series 1"].YValueMembers = "Total"; UsageLogConn.Close(); // data bind to the selected data source Chart1.DataBind(); cmd.Dispose(); The above code adds only one chart for one date and I have added 'chart1' to design view and its not created dynamic. But I wanted to add more charts dynamic at runtime to the webpage. Can anyone help me with this? I am using VS 2008, ASP.NET 3.5 and the charting lib is: using System.Web.UI.DataVisualization.Charting;

  • BitShifting with BigIntegers in Java

    - by ThePinkPoo
    I am implementing DES Encryption in Java with use of BigIntegers. I am left shifting binary keys with Java BigIntegers by doing the BigInteger.leftShift(int n) method. Key of N (Kn) is dependent on the result of the shift of Kn-1. The problem I am getting is that I am printing out the results after each key is generated and the shifting is not the expected out put. The key is split in 2 Cn and Dn (left and right respectively). I am specifically attempting this: "To do a left shift, move each bit one place to the left, except for the first bit, which is cycled to the end of the block. " It seems to tack on O's on the end depending on the shift. Not sure how to go about correcting this. Results: c0: 11110101010100110011000011110 d0: 11110001111001100110101010100 c1: 111101010101001100110000111100 d1: 111100011110011001101010101000 c2: 11110101010100110011000011110000 d2: 11110001111001100110101010100000 c3: 1111010101010011001100001111000000 d3: 1111000111100110011010101010000000 c4: 111101010101001100110000111100000000 d4: 111100011110011001101010101000000000 c5: 11110101010100110011000011110000000000 d5: 11110001111001100110101010100000000000 c6: 1111010101010011001100001111000000000000 d6: 1111000111100110011010101010000000000000 c7: 111101010101001100110000111100000000000000 d7: 111100011110011001101010101000000000000000 c8: 1111010101010011001100001111000000000000000 d8: 1111000111100110011010101010000000000000000 c9: 111101010101001100110000111100000000000000000 d9: 111100011110011001101010101000000000000000000 c10: 11110101010100110011000011110000000000000000000 d10: 11110001111001100110101010100000000000000000000 c11: 1111010101010011001100001111000000000000000000000 d11: 1111000111100110011010101010000000000000000000000 c12: 111101010101001100110000111100000000000000000000000 d12: 111100011110011001101010101000000000000000000000000 c13: 11110101010100110011000011110000000000000000000000000 d13: 11110001111001100110101010100000000000000000000000000 c14: 1111010101010011001100001111000000000000000000000000000 d14: 1111000111100110011010101010000000000000000000000000000 c15: 11110101010100110011000011110000000000000000000000000000 d15: 11110001111001100110101010100000000000000000000000000000

  • rails validation of presence not failing on nil

    - by holden
    I want to make sure an attibute exists, but it seems to still slip thru and I'm not sure how better to check for it. This should work, but doesn't. It's a attr_accessor and not a real attribute if that makes a difference. validates_presence_of :confirmed, :rooms {"commit"=>"Make Booking", "place_id"=>"the-kosmonaut", "authenticity_token"=>"Tkd9bfGqYFfYUv0n/Kqp6psXHjLU7CmX+D4UnCWMiMk=", "utf8"=>"✓", "booking"=>{"place_id"=>"6933", "bookdate"=>"2010-11-22", "rooms"=>[{}], "no_days"=>"2"}} Not sure why my form_for returns a blank hash in an array... <% form_for :booking, :url => place_bookings_path(@place) do |f| %> <%= f.hidden_field :bookdate, { :value => user_cart.getDate } %> <%= f.hidden_field :no_days, { :value => user_cart.getDays } %> <% for room in pricing_table(@place.rooms,@valid_dates) %> <%= select_tag("booking[rooms][][#{room.id}]", available_beds(room)) %> <% end %> <% end %>

  • iPhone SDK: Switching to one view then back to previous view errors

    - by Nic Hubbard
    I have a UITabBarConroller that I use to switch between 3 different views. This all works perfectly. On one of my tabs, I added a button at the to called "Add", I have added an outlet to this, as well as an IBAction method which looks like the following: // Method used to load up view where we can add a new ride - (IBAction)showAddNewRideView { MyRidesViewController *controller = [[MyRidesViewController alloc] initWithNibName:@"AddNewRide" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:controller animated:YES]; [controller release]; }//end showAddNewRideView This currently works fine, and loads up my AddNewRide nib file. But, once that view loads, I have a cancel button, which, when clicked, I want to return to the previous view. So, I figured I would just do the reverse of the above, using the following method which would load back my previous nib: - (IBAction)cancelAddingNewRide { MyRidesViewController *controller = [[MyRidesViewController alloc] initWithNibName:@"MainWindow" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:controller animated:YES]; [controller release]; }//end cancelAddingNewRide But, which trying to load the MainWindow nib, the program crashes, and I get the following error: 2010-05-05 20:24:37.211 Ride[6032:207] *** -[MyRidesViewController cancelAddingNewRide]: unrecognized selector sent to instance 0x501e450 2010-05-05 20:24:37.213 Ride[6032:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[MyRidesViewController cancelAddingNewRide]: unrecognized selector sent to instance 0x501e450' So, I am a little lost as to why it would work one way, but not the other.
