  • I want multipart/alternative; ActionMailer only sending text/html

    - by macek
    I'm following the Ruby on Rails Guide: ActionMailer Basics Section 2.7 Snippet: Action Mailer will automatically send multipart emails if you have different templates for the same action. So, for our UserMailer example, if you have welcome_email.text.plain.erb and welcome_email.text.html.erb in app/views/user_mailer, Action Mailer will automatically send a multipart email with the HTML and text versions setup as different parts. Well, I have both: app/views/user_mailer/welcome_mail.text.html.erb app/views/user_mailer/welcome_mail.text.plain.erb app/models/user_mailer.rb class UserMailer < ActionMailer::Base def welcome_mail(user) recipients user.email from "[email protected]" subject "Thanks for registering" body :user => user end end Any luck?

  • How do i get the default gateway in LINUX given the destination?

    - by Suezy
    Good day! I'm trying to get the default gateway, using the destination 0.0.0.0 i used this command: netstat -rn | grep 0.0.0.0 and it returns this list: Destination Gateway Genmask Flags MSS Window irtt Iface 10.9.9.17 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 133.88.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 133.88.31.70 0.0.0.0 UG 0 0 0 eth0 My goal here is to ping the default gateway using destination 0.0.0.0; thus, that is "133.88.31.70"; but this one returns a list because of using 'grep'. Question is: How do i get the default gateway only? I will need it for my bash script to identify if net connection is up or not. Any answers will be much appreciated. =)

What is happening though is that when I move onto the language list, and I go past Germany (~50% down the list?), the hover() loses focus and closes the original menu, which closes the language menu. Any idea's what is causing the issue? Any ideas how to fix the issue? I have tried the hoverIntent() plugin as well to no avail.

  • Does a program exist for checking two similar directories for file differences?

    - by John Sullivan
    Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ? Object.class : o.getClass(); } private Object[] getRecord(int rowIndex) { return (Object[]) data.get(rowIndex); } } public void valueChanged(ListSelectionEvent e) { if (!e.getValueIsAdjusting()) { ListSelectionModel lsm = (ListSelectionModel) e.getSource(); int index = lsm.getMinSelectionIndex(); if(model.getRecord(index)[0] == Boolean.FALSE) model.setValueAt(Boolean.TRUE, index, 0); else if(model.getRecord(index)[0] == Boolean.TRUE) model.setValueAt(Boolean.FALSE, index, 0); } } } Please reply soon as it is bugging me a lot Thank you in advance :)

  • Deleting a Collection with NHibernate Using the Criteria API

    - by lomaxx
    I think I know what the answer to this question is probably going to be, but I thought I'd go ahead and ask it anyway. It appears that within NHibernate if I do something like this: IList<Customer> customers = Session.CreateCriteria(typeof(Customer)) .Add(Restrictions.Eq("Name", "Steve") .List<Customer>(); And I want to then delete that list of customers. From what I can tell the only way to do it is like this: foreach(var customer in customers) { Session.Delete(customer); } But what I'm wondering is if there's any way I can just go: Session.Delete(customers); And delete the entire collection with a single call?

  • Jquery Ajaxform with input type=file and multifile

    - by crunchingnumbers
    Im using ajax form with multifile. However ajaxform just seems to quietly die and does not do anything if using multifile. Multifile is just a jquery plugin that builds a list of input type=file so that you can upload multiple files at once, before which you can add/delete your file upload list. I've looked at multifile and made one change to ensure that it generated a unique name as well as id which it didn't do before and i've checked the form elements multifile is building which all appear to be correct. From looking at ajaxform, it seems that it shoulld just generate the iframe as normal and post the multiple input type=file but it does nothing. Has anyone else experienced problems with multiple input type=file uploads

  • Foreach over a collection of IEnumerables

    - by sdr
    I have 3 IEnumerables that I want to iterate over. I want to do something like this: IEnumerable<Car> redCars = GetRedCars(); IEnumerable<Car> greenCars = GetGreenCars(); IEnumerable<Car> blueCars = GetBlueCars(); foreach(Car c in (redCars + greenCars + blueCars)) { c.DoSomething(); } ... The best way I can think of is: ... List<Car> allCars = new List(); allCars.AddRange(redCars); allCars.AddRange(greenCars); allCars.AddRange(blueCars); foreach(car in allCars) { ... } ... Is there a more concise way to do this? Seems like combinding IEnumberables should be trivial.

  • Optimal sorting algorithm with modified cost... [closed]

    - by David
    The numbers are in a list that is not sorted and supports only one type of operation. The operation is defined as follows: Given a position i and a position j the operation moves the number at position i to position j without altering the relative order of the other numbers. If i j, the positions of the numbers between positions j and i - 1 increment by 1, otherwise if i < j the positions of the numbers between positions i+1 and j decreases by 1. This operation requires i steps to find a number to move and j steps to locate the position to which you want to move it. Then the number of steps required to move a number of position i to position j is i+j. Design an algorithm that given a list of numbers, determine the optimal(in terms of cost) sequence of moves to rearrange the sequence.

  • Custom Collection Implementing IEnumerable

  • Eliminating matching values in a SQL result set

    - by Burgess Taylor
    I have a table with a list of transactions (invoices and credits) and I need to get a list of all the rows where the invoices and credits don't match up. eg user product value bill ThingA 200 jim ThingA -200 sue ThingB 100 liz ThingC 50 I only want to see the third and fourth rows, as the values of the others match off. I can do this if I select product, sum(value) ... group by product having sum(value) < 0 which works well, but I want to return the user name as well. As soon as I add the user to the select, I need to group by it as well, which messes it up as the amounts don't match up by user AND product. Any ideas ? I am using MS SQL 2000... Cheers

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • ghc can't find my cabal installed packages

    - by nont
    I've installed ghc 6.12.3, and then the Haskell Platform. I'm trying to compile a test program: $ ghc test.hs test.hs:3:0: Failed to load interface for `Bindings': Use -v to see a list of the files searched for. so, naturally, I do cabal install Bindings Which works fine, and places the package in ~/.cabal/lib/bindings-0.1.2 The problem is, that when I go to compile again with ghc, it still doesn't find the package I've installed with cabal. compiling in verbose mode gives: ghc -v test.hs Using binary package database: /home/ludflu/ghc/lib/ghc-6.12.3/package.conf.d/package.cache Using binary package database: /home/ludflu/.ghc/x86_64-linux 6.12.3/package.conf.d/package.cache As suggested by another stackoverflow user, I tried: ghc-pkg describe rts > rts.pkg vi rts.pkg # add the /home/ludflu/.cabal/lib to `library-dirs` field ghc-pkg update rts.pkg But to no avail. How to I add the .cabal to the list of package directories to search? Thank you!

  • Multiple LIKE in SQL

    - by ninumedia
    I wanted to search through multiple rows and obtain the row that contains a particular item. The table in mySQL is setup so each id has a unique list (comma-delimited) of values per row. Ex: id | order 1 | 1,3,8,19,34,2,38 2 | 4,7,2,190,38 Now if I wanted to pull the row that contained just the number 19 how would I go about doing this? The possibilities I could figure in the list with a LIKE condition would be: 19, ,19 ,19, I tried the following and I cannot obtain any results, Thank you for your help! SELECT * FROM categories WHERE order LIKE '19,%' OR '%,19%' OR '%,19%' LIMIT 0 , 30

  • How do I get Mathematica to thread a 2-variable function over two lists, using functional programmin

    - by Leah Wrenn Berman
    Lets say I have a function f[x_, y_], and two lists l1, l2. I'd like to evaluate f[x,y] where x runs over the list l1 and y runs over the list l2, and I'd like to do it without having to make all pairs of the form {l1[[i]],l2[[j]]}. (Motivation: I'm trying to implement some basic Haskell programs in Mathematica. In particular, I'd like to be able to code the Haskell program isMatroid::[[Int]]->Bool isMatroid b =and[or[sort(union(xs\\[x])[y]'elem'b|y<-ys]|xs<-b,ys<-b, xs<-x] I think I can do the rest of it, if I can figure out the original question, but I'd like the code to be Haskell-like. Any suggestions for implementing Haskell-like code in Mathematica would be appreciated.)

  • Multiple checkbox values search javascript

    - by JV10
    I have a list of keywords, and I've created a checkbox for each. My template has a form wrapping the content, so I can't have a nested form around the checkbox list. How can I send the selected checkbox values to my search results page? The form that wraps the content doesn't have any actions or methods applied: <form id="BoostMasterForm" runat="server"> This the HTML markup of my checkbox list: <div class="checkboxes"> <ul> <li> <input type="checkbox" name="search" class="options" value="one"> <label>one</label> </li> <li> <input type="checkbox" name="search" class="options" value="two"> <label>two</label> </li> <li> <input type="checkbox" name="search" class="options" value="three"> <label>three</label> </li> </ul> <input type="submit" value="Submit"/> </div> How can I use javascript or jQuery to submit the values of the multiple checkbox selections and on submit action them to the following URL: '/imagery/image-search.aspx' The resulting URL for a search where option 1 and 3 are submitted should be: '/imagery/image-search.aspx?search=one%20three' I'm using this javascript that I found on another post, however I need it to append the form an the action and the method. My website is ASP, where this post is for a PHP site: Sending multiple checkbox options $('.options').click(function() { var selectedItems = new Array(); $(".checkboxes input:checkbox[name=search]:checked").each(function() {selectedItems.push($(this).val());}); var data = selectedItems.join('|'); $("#opts").val(data); }); If anyone can help, it'd be greatly appreciated.

  • C# event or delegate or other solution?

    - by user295734
    Looking for some help or programmng ideas or mayeb there is some pattern that would help. Have an application that needs to fire alot of events sequentially, it could up to 100 or more unique events, it will be dynamic depeneding on the situation. Trying to find the best practice for doing this. My main idea right now is to create a list of objects iterate thru them, and fire each event. This seems wrong, or bad practice. Or maybe have one object and pass a list or params into one event? Or am I missing some feature in .NET that i could be using or implementing?
