  • Pull specific information from a long list with Perl

    - by melignus
    The file that I've got to work with here is the result of an LDAP extraction but I need to ultimately get the information formatted over to something that a spreadsheet can use. So, the data is as follows: DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: John Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Jane Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Ted Doe name: ##userName The format that I need to export to is: firstName lastName userName firstName lastName userName firstName lastName userName Where the spaces are tabs so I can then impor that file into a database. I have experience doing this in VBScript but I'm trying to switch over to using Perl for as much server administration as possible. I'm not sure on the syntax for what I want which is basically while not endoffile{ detect "displayName: " & $firstName & " " & $lastName detect "name: ##" & $userName write $firstName tab $lastName tab $userName to file } Also if someone could point me to a resource specifically on the text parsing syntax that Perl uses, I'd be very grateful. Most of the resources that I've come across haven't been very helpful.

  • Embedded CSS Media Queries Not Working

    - by Greg
    I am new to CSS media queries, and I was first trying to get pdf/mp3/mp4 buttons to get centered on this page whenever a mobile device is using it (http://www.mannachurch.org/portfolio-type/recycled-junk/). Keep in mind for that I am using a highly modified wordpress theme. So I tried experimenting to isolate this issue. However, I don't seem to have any control over using media queries and I can't even perform anything even on this simple HTML file: <!DOCTYPE html> <html> <head> <title>Title of the document</title> <style type="text/css"> body{background-color: blue;} @media only screen and (min-device-width : 599px) and (max-device-width : 600px) { body {background-color:black; } } </style> </head> <body> <p>This is an experiment<p/> </body> </html> What am I doing wrong?

  • Two part question about submitting bluetooth-enabled apps for the iPhone

    - by Kyle
    I have a couple questions about submitting blue-tooth enabled apps on the iPhone. I want to first say that bluetooth is merely an option in the application. The application does not completely rely on bluetooth as there are many modes the user can go in. First, do they require you to have the "peer-peer" key set in UIRequiredDeviceCapabilities even if bluetooth interface options can be disabled or hidden for non-bluetooth enabled devices? Basically, it's just an OPTION in the game and there are many other modes the player can play.. Does Apple not allow you to do that? I'm just curious, because it seems like something they would do. Adding to that, how do you check for it's functionality at runtime? In essence, how do you check UIRequiredDeviceCapabilities at runtime. I'm aware of checking iPhone device types, so would that be a proper way of going about it? I'm also sort of unaware which devices can run bluetooth gamekit, there doesn't seem to be a proper reference at the SDK site, or I'm unable to find it. Thanks for reading! [edit] I can confirm the existance of somebody rejected for submitting a bluetooth enabled app which didn't work on a iPhone 2G.. Of course, they didn't say if that was the MAIN function of the app, though.

  • javascript split() array contains

    - by Mahesha999
    While learning JavaScript, I did not get why the output when we print the array returned of the Sting.split() method (with regular expression as an argument) is as explained below. var colorString = "red,blue,green,yellow"; var colors = colorString.split(/[^\,]+/); document.write(colors); //this print 7 times comma: ,,,,,,, However when I print individual element of the array colors, it prints an empty string, three commas and an empty string: document.write(colors[0]); //empty string document.write(colors[1]); //, document.write(colors[2]); //, document.write(colors[3]); //, document.write(colors[4]); //empty string document.write(colors[5]); //undefined document.write(colors[6]); //undefined Then, why printing the array directly gives seven commas. Though I think its correct to have three commas in the second output, I did not get why there is a starting (at index 0) and ending empty string (at index 4). Please explain I am screwed up here.

  • CSS to create curved corner between two elements?

    - by Tauren
    My UI has an unordered list on the left. When a list item is selected, a div appears on the right of it. I'd like to have a curved outer corner where the <li> and the <div> meet. See the white arrow in the image below. To extend the blue <li> to the edge of the <ul>, I'm planning to do something like this: li { right-margin: 2em; border-radius: 8px; } li.active { right-margin: 0; border-bottom-right-radius: 0; border-top-right-radius: 0; } Is there a better way to extend the <li> to the edge of the <ul>? Obviously, I'll include the webkit and mozilla border radius CSS as well. The main thing I'm unsure about is that outer corner underneath the bottom right corner of the active <li>. I have some ideas, but they seem like hacks. Any suggestions? NOTE that the <ul> is indicated in grey, but it would be white in the real design. Also, I'm planning to use Javascript to position the <div> correctly when an <li> is selected.

  • Display: table-cell problems in chrome

    - by F21
    I have 3 divs that I would like to display as table cells: <div class="field"> <div class="row"> <label for="name">Subdomain</label> <input type="text" id="name" name="name"> <div class="subdomain-base ">test</div> </div> </div> This is the CSS that I am using: body{ font-size: 13px; } .field { width:450px; display: table; } .row { display: table-row; width: 100%; } .row > * { display: table-cell; border: 1px solid red; } label { width: 125px; height: 18px; } input { max-width: none; min-width: 0; overflow: auto; height: 18px; width: 100%; } .subdomain-base { height: 18px; width: 1px; } .subdomain-base { color: blue; font-size: 13px; } It works perfectly in Firefox 24: However, it has a height problem in Chrome 30 (latest): I have been trying all sorts of things to fix the problem with Chrome, but it seems like nothing works. Why is chrome getting that extra height? Jsfiddle: http://jsfiddle.net/ahLMH/

  • Why might my PHP log file not entirely be text?

    - by Fletcher Moore
    I'm trying to debug a plugin-bloated Wordpress installation; so I've added a very simple homebrew logger that records all the callbacks, which are basically listed in a single, ultimately 250+ row multidimensional array in Wordpress (I can't use print_r() because I need to catch them right before they are called). My logger line is $logger->log("\t" . $callback . "\n"); The logger produces a dandy text file in normal situations, but at two points during this particular task it is adding something which causes my log file to no longer be encoded properly. Gedit (I'm on Ubuntu) won't open the file, claiming to not understand the encoding. In vim, the culprit corrupt callback (which I could not find in the debugger, looking at the array) is about in the middle and printed as ^@lambda_546 and at the end of file there's this cute guy ^M. The ^M and ^@ are blue in my vim, which has no color theme set for .txt files. I don't know what it means. I tried adding an is_string($callback) condition, but I get the same results. Any ideas?

  • How to clear wxpython frame content when dragging a panel?

    - by aF
    Hello, I have 3 panels and I want to make drags on them. The problem is that when I do a drag on one this happens: How can I refresh the frame to happear its color when the panel is no longer there? This is the code that I have to make the drag: def onMouseMove(self, event): (self.pointWidth, self.pointHeight) = event.GetPosition() (self.width, self.height) = self.GetSizeTuple() if (self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15) or self.parent.dragging: self.SetCursor(wx.StockCursor(wx.CURSOR_SIZING)) """implement dragging""" if not event.Dragging(): self.w = 0 self.h = 0 return self.CaptureMouse() if self.w == 0 and self.h == 0: (self.w, self.h) = event.GetPosition() else: (posw, posh) = event.GetPosition() displacement = self.h - posh self.SetPosition( self.GetPosition() - (0, displacement)) else: self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) def onDraggingDown(self, event): if self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15: self.parent.dragging = 1 self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) self.SetBackgroundColour('BLUE') self.parent.SetTransparent(220) self.Refresh() def onDraggingUp(self, event): self.parent.dragging = 0 self.parent.SetTransparent(255) self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) and this are the binds for this events: self.Bind(wx.EVT_MOTION, self.onMouseMove) self.Bind(wx.EVT_LEFT_DOWN, self.onDraggingDown) self.Bind(wx.EVT_LEFT_UP, self.onDraggingUp) With this, if I click on the top of the panel, and move down or up, the panel position changes (I drag the panel) to the position of the mouse.

  • Is context:annotation-config an alternative to @AutoWired?

    - by Antacid
    Is it correct that I can put context:annotation-config in my XML config and it will automatically inject the bean class without needing any annotations? So instead of using these annotation types: public class Mailman { private String name; @Autowired private Parcel Parcel; public Mailman(String name) { this.name = name; } @Autowired public void setParcel(Parcel Parcel) { this.Parcel = Parcel; } @Autowired public void directionsToParcel(Parcel Parcel) { this.Parcel = Parcel; } } I would just need to write this: <beans ... > <bean id="mailMan" class="MailMan"> <constructor-arg value="John Doe"/> </bean> <bean id="parcel" class="Parcel" /> <context:annotation-config /> </beans> and then my MailMan class would look a lot simpler without the need for annotations: public class Mailman { private String name; private Parcel Parcel; public Mailman(String name) { this.name = name; } }

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • Floated element not included in parent, causing margin-bottom problems

    - by Christian Mann
    Right, so I've got a section of a page: <div class="article"> <div class="author"> <img src="images/officers/john_q_public_thm.jpg" /> <span class="name">John Q. Public</span> <span class="position">President</span> </div> <abbr class="postdate"> <span class="month m-01">Jan</span> <span class="day d-31">31</span> <span class="year y-2009">2009</span> </abbr> <div class="content"> <h2 class="title">Article Title</h2> <p>Pellentesque habitant morbi...facilisis luctus, metus</p> <p>Pellentesque habitant morbi...facilisis luctus, metus</p> </div> </div> <div class="article">...</div> <div class="article">...</div> The author and abbr divs are floated to the left. Each one of these article divs needs to be separated from its siblings by 5px or so. However, the author div is extending beyond the technical "height" of the div. The margin-bottom is doing nothing, as the space is being taken up by the floated author. This is somewhat difficult to envision, so I've placed it on my web server Is there any way to force the parent to be at least as tall as all of the floated elements within? If anyone figures out what I'm saying, thanks.

  • VB.NET Syntax Coding

    - by Yiu Korochko
    I know many people ask how some of these are done, but I do not understand the context in which to use the answers, so... I'm building a code editor for a subversion of Python language, and I found a very decent way of highlighting keywords in the RichTextBox through this: bluwords.Add(KEYWORDS GO HERE) If scriptt.Text.Length > 0 Then Dim selectStart2 As Integer = scriptt.SelectionStart scriptt.Select(0, scriptt.Text.Length) scriptt.SelectionColor = Color.Black scriptt.DeselectAll() For Each oneWord As String In bluwords Dim pos As Integer = 0 Do While scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) >= 0 pos = scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) scriptt.Select(pos, oneWord.Length) scriptt.SelectionColor = Color.Blue pos += 1 Loop Next scriptt.SelectionStart = selectStart2 End If (scriptt is the richtextbox) But when any decent amount of code is typed (or loaded via OpenFileDialog) chunks of the code go missing, the syntax selection falls apart, and it just plain ruins it. I'm looking for a more efficient way of doing this, maybe something more like visual studio itself...because there is NO NEED to highlight all text, set it black, then redo all of the syntaxing, and the text begins to over-right if you go back to insert characters between text. Also, in this version of Python, hash (#) is used for comments on comment only lines and double hash (##) is used for comments on the same line. Now I saw that someone had asked about this exact thing, and the working answer to select to the end of the line was something like: ^\'[^\r\n]+$|''[^\r\n]+$ which I cannot seem to get into practice. I also wanted to select text between quotes and turn it turquoise, such as between the first quotation mark and the second, the text is turquoise, and the same between the 3rd and 4th etcetera... Any help is appreciated!

  • Ruby and public_method_defined? : strange behaviour

    - by aXon
    Hi there Whilst reading through the book "The well grounded Rubyist", I came across some strange behaviour. The idea behind the code is using one's own method_missing method. The only thing I am not able to grasp is, why this code gets executed, as I do not have any Person.all_with_* class methods defined, which in turn means that the self.public_method_defined?(attr) returns true (attr is friends and then hobbies). #!/usr/bin/env ruby1.9 class Person PEOPLE = [] attr_reader :name, :hobbies, :friends def initialize(mame) @name = name @hobbies = [] @friends = [] PEOPLE << self end def has_hobby(hobby) @hobbies << hobby end def has_friend(friend) @friends << friend end def self.method_missing(m,*args) method = m.to_s if method.start_with?("all_with_") attr = method[9..-1] if self.public_method_defined?(attr) PEOPLE.find_all do |person| person.send(attr).include?(args[0]) end else raise ArgumentError, "Can't find #{attr}" end else super end end end j = Person.new("John") p = Person.new("Paul") g = Person.new("George") r = Person.new("Ringo") j.has_friend(p) j.has_friend(g) g.has_friend(p) r.has_hobby("rings") Person.all_with_friends(p).each do |person| puts "#{person.name} is friends with #{p.name}" end Person.all_with_hobbies("rings").each do |person| puts "#{person.name} is into rings" end The output is is friends with is friends with is into rings which is really understandable, as there is nothing to be executed.

  • Installing django on dreamhost (help a newb out)

    - by augustfirst
    I'm trying to get django running on my dreahost account. I've been trying to sort of use two tutorials at once: the one on the dreamhost wiki and the one in the django book. I installed django using the script on the wiki page, but I ran into trouble immediately while trying to work through the django book. It says: To start the server, change into your project directory (cd mysite), if you haven’t already, and run this command: python manage.py runserver This launches the server locally, on port 8000, accessible only to connections from your own computer. Now that it’s running, visit 127.0.0.1:8000 with your Web browser. You’ll see a “Welcome to Django” page shaded in a pleasant pastel blue. It worked! Those instructions seem to assume that you're developing locally, not on a shared server. Where the heck am I supposed to look for the "Welcome to Django" page after starting the server? In my webroot? No dice. Anyway, I tried to blunder ahead through the django book to its hello world tutorial (chapter 3). But once I've edited the view file and the URLconf, I don't get a nice clean "hello world" text. Instead (as you can see) I get an "import error". Any help would be greatly appreciated.

  • Most efficient way to make an activity log

    - by Nathan
    I am making a "recent activity" tab to profiles on my site and I also am going to have a log for moderators to see everything that happens on the site. This would require making an activity log of some sort. I just don't know what would be better. I have 2 options: Make a table called "activity" and then every time someone does something, add a record to it with the type of action, user id, timestamp, etc. Problem: table could get very long. Join all 3 tables (questions, answers, answer_comments) and then somehow show all these on the page in the order in which the action was taken. Problem: this would be extremely hard because I have no clue how I could make it say "John commented on an answer on Question Title Here" by just joining 3 tables. Does anyone know of a better way of making an activity log in this situation? I am using PHP and MySQL. If this is either too inefficient or hard I will probably just forget the Recent Activity tab on profiles but I still need an activity log for moderators. Here's some SQL that I started making for option 2, but this would not work because there is no way of detecting whether the action is a comment, question, or answer when I echo the info in a while loop: SELECT q.*, a.*, ac.* FROM questions q JOIN answers a ON a.questionid = q.qid JOIN answer_comments ac ON c.answerid = a.ans_id WHERE q.user = $userid AND a.userid = $userid AND ac.userid = $userid ORDER BY q.created DESC, a.created DESC, ac.created DESC Thanks in advance for any help!

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

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

  • How to (kindly) ask your users to upgrade from IE6?

    - by nickf
    It's no secret at all that IE6 has been a major roadblock to the advancement of the web over the last few years. I couldn't count the number of hours I've spent bashing my head against a wall trying to fix or debug IE6 issues. The way I see it, there are two types of IE6 user. a) the poor corporate schmoe whose IT department doesn't want to upgrade in case something breaks, and b) the mums and dads of the world who think the internet is the blue E on their desktop (and I don't mean that in a nasty way). There's probably a couple of people who know about all the other browsers, but still choose to run IE6. They get what they deserve, IMO. Anyway, getting to the point, I'd say that 90% of my IE6-using visitors are in the the mums and dads category - they're not stupid, they just don't know WHY they should upgrade to IE7 or Firefox or whatever. How do I educate these people without pissing them off? Is there a nice and friendly website I can direct these people to, which explains the reasons for upgrading in plain language? Any mention of "security" or "web standards" I think would just come across as scary. I've just seen http://www.whatbrowser.org which seems to fit the bill nicely. It explains in very basic terms: what a web browser is why you'd want to upgrade it how old your current browser is (subtle hint to those with a 9 year old browser) ..aaaand it's in 22 languages. It's from Google but displays no bias (it links to Firefox, Chrome, Opera, Safari, Internet Explorer displayed in a random order).

  • Change Rectangle Fill Based on ColumnWidth of a grid

    - by Coesy
    Essentially i want to do as the title says, if the columnwidth is .50 then the rectangle should be red, if it's .75 then it should be amber, and if it's 1 then it should be green. I thought I could achieve this with DataTriggers but for some reason I am getting "Object Reference Not Set To An Instance Of An Object" error, here is my code, am I missing something here? FYI the width property will be changed in the backend through a timer_tick event. <Grid x:Name="Grid1" Width="300" Height="30"> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="MyColumn1" Width=".50*"></ColumnDefinition> <ColumnDefinition x:Name="MyColumn2" Width=".50*"></ColumnDefinition> </Grid.ColumnDefinitions> <Grid.Triggers> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".50*"> <Setter TargetName="rect" Property="Fill" Value="Red"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".75*"> <Setter TargetName="rect" Property="Fill" Value="Yellow"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value="1"> <Setter TargetName="rect" Property="Fill" Value="Green"></Setter> </DataTrigger> </Grid.Triggers> <Rectangle x:Name="rect" Grid.Column="0" HorizontalAlignment="Stretch"></Rectangle> <Rectangle Grid.Column="1" Fill="Blue"></Rectangle> </Grid>

  • jquery selecting all elements except the last per group

    - by Anthony
    I have a table that looks like: <table> <tr> <td>one</td><td>two</td><td>three</td><td>last</td> </tr> <tr> <td>blue</td><td>red</td><td>green</td><td>last</td> </tr> <tr> <td>Monday</td><td>Tuesday</td><td>Wednesday</td><td>last</td> </tr> </table> What I want is a jquery selector that will choose all but the last td of each table row. I tried: $("tr td:not(:last)").css("background-color","red"); //changing color just as a test... But instead of all cells but the last on each row being changed, all cells but the very last one in the table are selected. Similarly, if I change it to: $("tr td:last").css("background-color","red"); the only one that changes is the very last cell. How do I choose the last (or not last) of each row?

  • javascript check function for a html form

    - by Reteras Remus
    I'm having a problem with a HTML form (name, e-mail, subject, message), I can't validate the form if it was completed correct or not. I want to call a javascript function when the form is submitted and alert if a field wasn't completed correct. My problem is with the submit button, because my boss said that I must use he's own php function to insert a submit button. The php function looke like: function normal_button($text, $width, $param = '', $class = 'button-blue') { $content = '<div class="'.$class.'" style="width:'.$width.'px;" '.$param.'>'.$text.'</div>'; return $content; } and how I call the function: echo normal_button('Send it', '100', 'onclick="document.getElementById(\'emailForm\').submit();" '); I tried to call the js function declaring the onSubmit="return checkForm(this)" in the <form action='email.php' method='post'> HTML form, but I can't "catch" the submit. Also I tried to catch it with jquery, $(document).ready(function() { $('.normal_button').click(function() { }); ); but I can't return false if a field wasn't completed correct. I must use he's PHP function to insert the submit button, but how can I "catch" the fields, how can I validate them? Any suggestions? Thank you !

  • How can I change the tags/css class of some dynamic text based on output from a helper?

    - by Angela
    I have a repeated line which outputs something like: Call John Jones in -3 days (status) I have a helper called show_status(contact,email) which will output whether that particular email had been sent to that particular contact. If it is "sent," then that entire line should show up as "strike out." Similarly, if the number of days is -3 (<0), the line should be formatted in red. Here's my hack, but there must be a cleaner way to put the logic into the controller? I hard-code a value that wraps around the lines I want formatted, and assign the value based on a separate call to the same helper: <% for call in @campaign.calls %> <% if !show_call_status(@contact,call).blank? %> <%= strike_start = '<s>'%> <%= strike_end = '</s>' %> <% end %> <p> <%= strike_start %> <%= link_to call.title, call_path(call) %> on <%= (@contact.date_entered + call.days).to_s(:long) %> in <%= interval_email(@contact,call) %> days <%= make_call(@contact,call) %> <span class='status'><%= show_call_status(@contact,call) %></span> <%= strike_end %> </p> <% end %> I guess what I'd like to do is not have the if statement in the View. Not sure how to do this.
