  • Getting the image URL without the HTML in Rails

    - by tesmar
    Hi, In Rails is there a way to get the URL to the image (going through the assets_host) and just return the URL of the image? I want to use assets_host data in my Javascript, but I just need to insert the URL into the JS, not the whole image_tag. Thank you in advance!

    In PHP I am able to retrieve information from a db like so: <?php $sql = "SELECT * FROM users"; $result = mysql_query($sql); $data = array(); while($row = mysql_fetch_assoc($result)) { $data[] = $row; } I am trying to acomplish the same thing in C#: OdbcCommand cmd = new OdbcCommand("SELECT * FROM users WHERE id = @id"); cmd.Parameters.Add("@id", id); OdbcDataReader reader = cmd.ExecuteReader(); Dictionary<string, string> data = new Dictionary<string, string>(); while (reader.Read()) { data.Add("id", reader.GetString(0)); data.Add("username", reader.GetString(1)); data.Add("firstName", reader.GetString(2)); } return data; Is it possible to reference the column in the table by name without going through all this trouble?

  • [SQL] Getting the sum of several columns from two tables

    - by romaintaz
    I want to get the sum of several columns from 2 different tables (these tables share the same structure). If I only consider one table, I would write this kind of query: SELECT MONTH_REF, SUM(amount1), SUM(amount2) FROM T_FOO WHERE seller = XXX GROUP BY MONTH_REF; However, I would like to also work with the data from the table T_BAR, and then have a select query that return the following columns: MONTH_REF SUM(T_FOO.amount1) + SUM(T_BAR.amount1) SUM(T_FOO.amount2) + SUM(T_BAR.amount2) everything grouped by the value of MONTH_REF. Note that a record for a given MONTH_REF can be found in one table but not in the other table. In this case, I would like to get the sum of T_FOO.amount1 + 0 (or 0 + T_BAR.amount1). How can I write my SQL query to get this information? For information, my database is Oracle 10g.

  • Getting age in years in a SQL query

    - by Earlz
    Hello I've been tasked with doing a few queries on a large SQL Server 2000 database. The query I'm having trouble with is "find the number of people between ages 20 and 40" How would I do this? My previous query to get a count of everyone looks like this: select count(rid) from people where ... (with the ... being irrelevant conditions). I've googled some but the only thing I've found for calculating age is so large that I don't see how to embed it into a query, or it is a stored procedure which I do not have the permissions to create. Can someone help me with this?

  • Getting Factors of a Number

    - by Dave
    Hi Problem: I'm trying to refactor this algorithm to make it faster. What would be the first refactoring here for speed? public int GetHowManyFactors(int numberToCheck) { // we know 1 is a factor and the numberToCheck int factorCount = 2; // start from 2 as we know 1 is a factor, and less than as numberToCheck is a factor for (int i = 2; i < numberToCheck; i++) { if (numberToCheck % i == 0) factorCount++; } return factorCount; }

  • Getting MAX_INT from NSDateComponents

    - by MattyW
    I'm trying to write my first iPhone app, and I'm using a date picker object for the user to enter their date of birth. Part of my app requires the year in int format. I've added the code as below. What's odd is that 'month' gets the right value. But day and year seem to be stuck at MAX_INT (2147483647). Can anyone tell me what I'm doing wrong? -(IBAction)dateOfBirthChanged:(id)sender { NSCalendar* calender = [NSCalendar currentCalendar]; NSDateComponents* dateComponents = [calender components:NSMonthCalendarUnit fromDate:[datepicker date]]; NSInteger day = [dateComponents day]; NSInteger month = [dateComponents month]; NSInteger year = [dateComponents year]; label.text = [NSString stringWithFormat:@"Your year of birth is %d", year]; }

  • Ruby getting the diagonal elements in a 2d Array

    - by Calm Storm
    Hi, I was trying some problems with my 2D ruby array and my LOC reduces a lot when I do array slicing. So for example, require "test/unit" class LibraryTest < Test::Unit::TestCase def test_box array = [[1,2,3,4],[3,4,5,6], [5,6,7,8], [2,3,4,5]] puts array[1][2..3] # 5, 6 puts array[1..2][1] # 5, 6, 7, 8 end end I want to know if there is a way to get a diagonal slice? Lets say I want to start at [0,0] and want a diagonal slice of 3. Then I would get elements from [0,0], [1,1], [2,2] and I will get an array like [1,4,7] for example above. Is there any magic one-liner ruby code that can achieve this? 3.times do {some magic stuff?}

  • Beginner question about getting reference to cin

    - by John C
    I'm having problems wrapping my head around this. I have a function void foo(istream& input) { input = cin; } This fails (I'm assuming because cin isn't supposed to be "copyable". however, this works void foo(istream& input) { istream& baz = cin; } Is there a reason that I can get a reference to cin in baz but I cannot assign it to input? Thanks

  • Getting the old value of a asp.net control on postback

    - by D3no
    I want to be able to find the old value of a asp.net control (textbox, checkbox etc) without relying on events (e.g. OnTextChange event). Something like "someTextboxControl.OldText" would be perfect! I imagine that it is stored in the viewstate and need to somehow get at it via a custom control. Any ideas?

  • Getting SharePoint absolute site url

    - by Francis
    I need to get the current absolute url of my site from inside an aspx page (no codebehind). I tried $SPUrl, but it get's converted into a relative url. <asp:Literal runat="server" text="<% $SPUrl:~Site/mypage.aspx %>" /> results in "/mypage.aspx". It's important that I get the full absolute url starting with "http://". <asp:Literal runat="server" text="<% $SPUrl:~SiteCollection/mypage.aspx %>" /> does the same. The goal is to get this url: "http://myspweb.com/mypage.aspx" as result.

  • Getting all selected checkboxes in an array

    - by Click Upvote
    So I have these checkboxes: <input type="checkbox" name="type" value="4" /> <input type="checkbox" name="type" value="3" /> <input type="checkbox" name="type" value="1" /> <input type="checkbox" name="type" value="5" /> And so on. There are about 6 of them and are hand-coded (i.e not fetched from a db) so they are likely to remain the same for a while. My question is how I can get them all in an array (in javascript), so I can use them while making an AJAX $.post request using Jquery. Any thoughts? Edit: I would only want the selected checkboxes to be added to the array

  • Image not getting displayed on a JPanel.

    - by Myth17
    class Deal implements ActionListener { public void actionPerformed(ActionEvent e) { dl.setDeck(); dl.shuffle(); dl.firstDraw(pl); for(Card c:pl.showHand()) panelplay.add(new JLabel(c.getImageIcon())); panelplay.validate(); } } This is an event handler for a Jbutton. The method pl.showHand() returns a ArrayList of a user defined class 'Card'. Inserting a println() inside the loop shows the print, so the code is being executed but the Panel panelplay isnt showing card Images.

  • Backing Bean not getting values sent by javascript

    - by Developer106
    I have three drop down lists whose values are been copied to <h:inputHidden> components by the following JavaScript function: function getBirthDate() { var months = document.getElementById("months") var hidden1 = document.getElementById("formsignup:monthField"); hidden1.value = months.options[months.selectedIndex].text; var days = document.getElementById("days"); var hidden2 = document.getElementById("formsignup:dayField"); hidden2.value = days.options[days.selectedIndex].value; var years = document.getElementById("years"); var hidden3 = document.getElementById("formsignup:yearField"); hidden3.value = years.options[years.selectedIndex].value; } Here are the three <h:inputHidden> components: <h:inputHidden value="#{signupBean.month}" id="monthField"/> <h:inputHidden value="#{signupBean.day}" id="dayField"/> <h:inputHidden value="#{signupBean.year}" id="yearField"/> This is the command button that is supposed to invoke the function that copies the values to the inputs and then submits them to the backing bean. <h:commandButton image="images/images/signup1.png" styleClass="joinnow" id="joinus" action="#{signupBean.save}" onclick="getBirthDate()" /> But they arrive as null in the backing bean. How is this caused and how can I solve it?

  • User control events not getting to their handlers

    - by PhrkOnLsh
    I am trying to create a user control to wrap around the Membership API (A set of custom Gridviews to display the data better) and, while the code and the controls worked fine in the page, when I moved them to an .ascx, the events stopped firing to it. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomMembership.ascx.cs" Inherits="CCGlink.CustomMembership" %> <asp:Panel ID="mainPnl" runat="server"> <asp:Label id="lblError" ForeColor="Red" Font-Bold="true" runat="server" /> <asp:GridView id="grdUsers" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" OnRowUpdating="grdUsers_RowUpdating" OnRowDeleting="grdUsers_RowDeleting" OnRowCancelingEdit="grdUsers_cancelEdit" autogeneratecolumns="false" allowsorting="true" AllowPaging="true" EmptyDataText="No users..." pagesize="<%# PageSizeForBoth %>" runat="server"> <!-- ...columns... --> </asp:GridView> <asp:Button id="btnAllDetails" onclick="btnAllDetails_clicked" text="Full Info" runat="server" /> <asp:GridView DataKeyNames="UserName" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" id="grdAllDetails" visible="false" allowsorting="true" EmptyDataText="No users in DB." pagesize="<%# PageSizeForBoth %>" runat="server" /> <asp:Button id="btnDoneAllDetails" onclick="btnAllDetails_clicked" text="Done." Visible="false" runat="server" /> </asp:Panel> However, none of the events in the first two controls (the gridview grdUsers and the button btnAllDetails) simply do NOT occur, I have verified this in the debugger. If they occured just fine in the aspx page, why do they die on moving to the ascx? My code in the aspx now is: <div class="admin-right"> <asp:ScriptManager ID="sm1" runat="server" /> <h1>User Management</h1> <div class="admin-right-users"> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <cm1:CustomMembership id="showUsers" PageSizeForBoth="9" AlternatingRowStylecssclass="alternating" RowStylecssclass="row" DataSource="srcUsers" HeaderStylecssclass="header" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> Thanks.

  • Coffeescript getting proper scope from callback method

    - by pandabrand
    I've searched for this and can't seem to find an successful answer, I'm using a jQuerey ajax call and I can't get the response out to the callback. Here's my coffeescript code: initialize: (@blog, @posts) -> _url = @blog.url _simpleName = _url.substr 7, _url.length _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128' $.ajax url: _avatarURL dataType: "jsonp" jsonp: "jsonp" (data, status) => handleData(data) handleData: (data) => console.log data @avatar = data Here's the compiled JS: Blog.prototype.initialize = function(blog, posts) { var _avatarURL, _simpleName, _url, _this = this; this.blog = blog; this.posts = posts; _url = this.blog.url; _simpleName = _url.substr(7, _url.length); _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128'; return $.ajax({ url: _avatarURL, dataType: "jsonp", jsonp: "jsonp" }, function(data, status) { return handleData(data); }); }; Blog.prototype.handleData = function(data) { console.log(data); return this.avatar = data; }; I've tried a dozen variations and I can't figure out how to write this? Thanks.

  • Getting a substring in Ruby by x number of chars

    - by wotaskd
    I'm trying to produce some Ruby code that will take a string and return a new one, with a number x number of characters removed from its end - these can be actual letters, numbers, spaces etc. Ex: given the following string a_string = "a1wer4zx" I need a simple way to get the same string, minus - say - the 3 last digits. In the case above, that would be "a1wer". The way I'm doing it right now seems very convoluted: an_array = a_string.split(//,(a_string.length-2)) an_array.pop new_string = an_array.join Any ideas?
