  • how to change the value to a name depending on case

    - by ZeroSoul13
    i've created a select button with 3 option <%= f.label :prioridad %><br/> <%= f.select :prioridad, options_for_select([['Alta', 1], ['Medio', 2], ['Baja', 3]]) %> The value gets inserted to the DataBase but when i display it i see the number op the option selected (which is correct). What i would like to know is how i can change that so on the index the user can see the name and not the value: def convertidor case llamada.prioridad when prioridad == '1' puts "Alta" when prioridad == '2' puts "Media" else puts "Baja" end end This didn't worked.

    Hi, I've the following model and I want to execute a method on save and update, problem is that the hook is not being executed on update. class User include DataMapper::Resource include BCrypt property :id, Serial property :email, String, :index => true property :crypted_password, String, :accessor => :private ... attr_accessor :password, :password_confirmation before :save, :encrypt_password! # also tried the following with no success: # before :update, :encrypt_password! # and tried this but hell was never raised # before :update do # raise 'hell' # end def encrypt_password! self.crypted_password = Password.create password end end This spec fails: it 'should call encrypt_password! on update' do subject.save.should be_true subject.should_receive(:encrypt_password!) subject.update(:password => 'other-password', :password_confirmation => 'other-password').should be_true end And this passes: it 'should call encrypt_password! on create' do subject.should_receive(:encrypt_password!) subject.save.should be_true end I've also tried with after :update in addition to after :save with no success.

  • Passing value from :locals to link_remote_to

    - by Teef L
    In my edit.haml file, I have =render :partial => 'old_question_tags', :locals => {:current_question => @question.id}. I'd like to pass the value in :current_question to a link_to_remote call in _old_question_tags.haml: #{link_to_remote image_tag('red-x.png', {:alt => "Remove #{t.name} tag"}), :url => {:action => 'remove_old_tag_from_question', :tag_remove => t.id, :current_question => current_question}} But I get this error on the link_to_remote line: ActionView::TemplateError (undefined local variable or method `current_question' for #<ActionView::Base:0xdb2fec8>) In _old_question_tags.haml, if I just print current_question (using =current_question), it prints the number without any problems. How do I properly pass that value to the partial so that I can pass it to the link_to_remote call?

  • Javascript not registering/executing after button click

    - by rs
    I have a textbox which i convert to tinymce textbox using tinymce.js file. I'm trying to add a new script with database fields substituted based on selection made from dropdownlist to page using registerstartupscript. In page load protected sub page_load(byVal sender as object, byval e as EventArgs) handles me.load AddScriptToPage() if not page.ispostback() then session("fname") = nothing end if end sub Script Method Sub AddScriptToPage() dim _script = " c.onRenderMenu.add(function(c, m) { " & _ add_columns() & _ "}); " ClientScript.RegisterStartupScript(Me.GetType(), keyword,_script) End Sub function add_columns() as string dim ret_string = String.empty select case ddlList.selectedvalue case 1 sqlcommand = "xyz" case 2 sqlcommand = "xyz" case 3 //Load from excel sqlcommand = nothing end select if sqlcommand isnot nothing then executereader() while reader.read() ret_string = ret_string & reader("column") end while elseif session("fname") isnot nothing dt = getdatatable(session("fname").tostring()) //method that opens oledb connection and returns columns for each dr in dt.rows ret_string = ret_string & dr("column") next end if add_columns = ret_string end function When excel file is uploaded to server this event is called protected sub btnclick(byVal sender as object, byval e as EventArgs) if hasfile then 'i have custom properties set after control validation 'Upload file 'set session value with filepath session("fname") = filepath 'call js register event AddScriptToPage() end if end sub When i click upload button i'm calling AddScriptToPage, and debug it it hits AddScripttoPage event and executes it but it doesn't showup on page. It should show column names in tinymce editor but it doesn't. But when i click another button on the same page it shows (becos session has the filename). On Upload button click page flow: Page load - AddScriptToPage is executed (registers scripts with no columns) Then AddScriptToPage in btnclick event is executed (registers scripts with columns) Why is this script not getting registered even though it is executed on vb code on uploadclick event? And why does it show up after another button click and not original button click that calls this event?

  • How can I spec out an authlogic sessions controller using using a stub?

    - by Dave
    I want to test my User Session Controller testing that a user session is first built then saved. My UserSession class looks like this: class UserSession < Authlogic::Session::Base end The create method of my UserSessionsController looks like this: def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Successfully logged in." redirect_back_or_default administer_home_page_url else render :new end end and my controller spec looks like this: describe UserSessionsController do it "should build a new user session" do UserSession.stub!(:new).with(:email, :password) UserSession.should_receive(:new).with(:email => "[email protected]", :password => "foobar") post :create, :user_session => { :email => "[email protected]", :password => "foobar" } end end I stub out the new method but I still get the following error when I run the test: Spec::Mocks::MockExpectationError in 'UserSessionsController should build a new user session' <UserSession (class)> received :new with unexpected arguments expected: ({:password=>"foobar", :email=>"[email protected]"}) got: ({:priority_record=>nil}, nil) It's although the new method is being called on UserSession before my controller code is getting called. Calling activate_authlogic makes no difference.

  • Customizing the Stars Image for Ajaxful_Rating RoR plugin

    - by Kevin
    I'm trying to come up with my own star image that's slightly smaller and different style than the one provided in the gem/plugin, but Ajaxful_rating doesn't have an easy way to do this. Here's what I've figured out so far: The stars.png in the public folder is three 25x25 pixel tiles stacked vertically, ordered empty star, normal star, and hover star. I'm assuming as long as you keep the above constraints, you should be fine without modifying any other files. But what if you want to change the image size of the stars to larger or smaller? I've found where you can change the height in the stylesheets/ajaxful_rating.css .ajaxful-rating{ position: relative; /*width: 125px; this is setted dynamically */ height: 25px; overflow: hidden; list-style: none; margin: 0; padding: 0; background-position: left top; } .ajaxful-rating li{ display: inline; } .ajaxful-rating a, .ajaxful-rating span, .ajaxful-rating .show-value{ position: absolute; top: 0; left: 0; text-indent: -1000em; height: 25px; line-height: 25px; outline: none; overflow: hidden; border: none; } You just need to change every place that says "25px" above to whatever height your new star image is. This works fine but doesn't display the horizontal part correctly. Anyone know where I would look to set the horizontal part as well? (I'm assuming it's in an .rb file somewhere based upon how many stars you specified in your ajaxful_rating setup)

  • Removing a pattern from the beggining and end of a string in ruby

    - by seaneshbaugh
    So I found myself needing to remove <br /> tags from the beginning and end of strings in a project I'm working on. I made a quick little method that does what I need it to do but I'm not convinced it's the best way to go about doing this sort of thing. I suspect there's probably a handy regular expression I can use to do it in only a couple of lines. Here's what I got: def remove_breaks(text) if text != nil and text != "" text.strip! index = text.rindex("<br />") while index != nil and index == text.length - 6 text = text[0, text.length - 6] text.strip! index = text.rindex("<br />") end text.strip! index = text.index("<br />") while index != nil and index == 0 text = test[6, text.length] text.strip! index = text.index("<br />") end end return text end Now the "<br />" could really be anything, and it'd probably be more useful to make a general use function that takes as an argument the string that needs to be stripped from the beginning and end. I'm open to any suggestions on how to make this cleaner because this just seems like it can be improved.

  • What are options for GWT to C++ communication?

    - by seas
    I am looking for GWT to C++ communication solution. Currently I am trying to figure out how to run WSDL in GWT, but actually, have absolutely no experience in WSDL, and only little in GWT. So, my question is about feasibility of working with WSDL in GWT (and how?) and other approaches would also be interesting if exist. I am trying to avoid coding Java on the server and coding JavaScript on client.

  • Why does Google append while(1); in front of their JSON responses?

    - by Andrew Koester
    This is something I've always been curious about, is exactly why Google appends while(1); in front of their (private) JSON responses. For example, here's a response while turning a calendar on and off in Google Calendar: while(1);[['u',[['smsSentFlag','false'],['hideInvitations','false'],['remindOnRespondedEventsOnly','true'],['hideInvitations_remindOnRespondedEventsOnly','false_true'],['Calendar ID stripped for privacy','false'],['smsVerifiedFlag','true']]]] I would assume this is to prevent people from doing an eval() on it, but all you'd really have to do is replace the while and then you'd be set. I would assume eval prevention is to make sure people write safe JSON parsing code. I've seen this used in a couple other places, too, but a lot more so with Google (Mail, Calendar, Contacts, etc.) Strangely enough, Google Docs starts with &&&START&&& instead, and Google Contacts seems to start with while(1); &&&START&&&. Does anyone know what's going on here?

  • Ordering by Sum from a separate controller part 2

    - by bgadoci
    Ok, so I had this working just fine before making a few controller additions and the relocation of some code. I feel like I am missing something really simple here but have spent hours trying to figure out what is going on. Here is the situation. class Question < ActiveRecord::Base has_many :sites end and class Sites < ActiveRecord::Base belongs_to :questions end I am trying to display my Sites in order of the sum of the 'like' column in the Sites Table. From my previous StackOverflow question I had this working when the partial was being called in the /views/sites/index.html.erb file. I then moved the partial to being called in the /views/questions/show.html.erb file and it successfully displays the Sites but fails to order them as it did when being called from the Sites view. I am calling the partial from the /views/questions/show.html.erb file as follows: <%= render :partial => @question.sites %> and here is the SitesController#index code class SitesController < ApplicationController def index @sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total", :joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id", :group => "sites.id", :order => "like_total DESC") respond_to do |format| format.html # index.html.erb format.xml { render :xml => @sites } end end

  • How do I connect multiple sortable lists to each other in jQuery UI?

    - by Abs
    I'm new to jQuery, and I'm totally struggling with using jQuery UI's sortable. I'm trying to put together a page to facilitate grouping and ordering of items. My page has a list of groups, and each group contains a list of items. I want to allow users to be able to do the following: 1. Reorder the groups 2. Reorder the items within the groups 3. Move the items between the groups The first two requirements are no problem. I'm able to sort them just fine. The problem comes in with the third requirement. I just can't connect those lists to each other. Some code might help. Here's the markup. <ul id="groupsList" class="groupsList"> <li id="group1" class="group">Group 1 <ul id="groupItems1" class="itemsList"> <li id="item1-1" class="item">Item 1.1</li> <li id="item1-2" class="item">Item 1.2</li> </ul> </li> <li id="group2" class="group">Group 2 <ul id="groupItems2" class="itemsList"> <li id="item2-1" class="item">Item 2.1</li> <li id="item2-2" class="item">Item 2.2</li> </ul> </li> <li id="group3" class="group">Group 3 <ul id="groupItems3" class="itemsList"> <li id="item3-1" class="item">Item 3.1</li> <li id="item3-2" class="item">Item 3.2</li> </ul> </li> </ul> I was able to sort the lists by putting $('#groupsList').sortable({}); and $('.itemsList').sortable({}); in the document ready function. I tried using the connectWith option for sortable to make it work, but I failed spectacularly. What I'd like to do is have the every groupItemsX list connected to every groupItemsX list but itself. How should I do that?

    module FooHelper def foo haml_tag(:div) do haml_content("bar") end end end When I test this I get: NoMethodError: undefined method `haml_tag' This code is perfectly valid and works in a development/production environment. It's something to do with having the haml helpers properly loaded in the test environment. Thanks!

  • Detecting regional settings (List Separator) from web

    - by Toms Mikoss
    After having the unpleasant surprise that Comma Seperated Value (CSV) files are not necessarily comma-separated, I'm trying to find out if there is any way to detect what the regional settings list separator value is on the client machine from http request. Scenario is as follows: A user can download some data in CSV format from web site (RoR, if it matters). That CSV file is generated on the fly, sent to the user, and most of the time double-clicked and opened in MS Excel on Windows machine at the destination. Now, if the user has ',' set as the list separator, the data is properly arranged in columns, but if any other separator (';' is widely used here) is set, it all just gets thrown into a single column. So, is there any way to detect what separator is used on the client machine, and generate the file accordingly? I have a sinking feeling that it is not, but I'd like to be sure before I pass the 'can't be done, sorry' line to the customer :)

  • How do I view how many concurrent long polling requests there are on my server?

    - by Pascal
    My host is Joyent. My host says I have 15 process limit and prstat -J shows those processes but that doesn't tell me how many long polling requests are currently being served. I could record it myself but that would add alot of performance overhead. I need to know when the server is at its long polling limits. I know this limit occurs far before the memory or CPU is used up. From experimentation, I've already verified that the number of long polls open is NOT equivalant to the number of processes running, probably because each process has multiple threads, each serving a request. thanks.

  • UpdatePanel Full Postback

    - by Korivo
    Greetings, here is the scenario. I have and .aspx page with and updatepanel like this <asp:UpdatePanel id="uPanelMain" runat="server"> <ContentTemplate> <uc:Calendar id="ucCalendar" runat="server" Visible="true" /> <uc:Scoring id="ucScoring" runat="server" Visible="false" /> </ContentTemplate> The control ucCalendar is loaded first and it contains a grid like this <asp:DataGrid CssClass="grid" ID="gridGames" runat="server" AutoGenerateColumns="False" HeaderStyle-CssClass="gridHeader" ItemStyle-CssClass="gridScoringRow" GridLines="None" ItemStyle-BackColor="#EEEEEE" AlternatingItemStyle-BackColor="#F5F5F5" OnEditCommand="doScoreGame" OnDeleteCommand="doEditGame" OnCancelCommand="printLineup" OnItemDataBound="gridDataBound"> <Columns> <asp:TemplateColumn > <ItemTemplate> <asp:CheckBox ID="chkDelete" runat="server" /> </ItemTemplate> </asp:TemplateColumn> <asp:BoundColumn DataField="idGame" Visible="false" /> <asp:BoundColumn DataField="isClose" Visible="false" /> <asp:TemplateColumn HeaderText="Status"> <ItemTemplate> <asp:Image ID="imgStatus" runat="server" ImageUrl="~/img/icoX.png" alt="icoStatus" /> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn> <ItemTemplate> <asp:LinkButton ID="linkScore" runat="server" CommandName="Edit" Text="Score" /> </ItemTemplate> </asp:TemplateColumn> </Columns> </asp:DataGrid> So when i click the "linkButton", the codebehind of the userControl calls a public method in the .aspx as this: From the userControl protected void doScoreGame(object sender, DataGridCommandEventArgs e) { ((GM)this.Page).showScoring(null, null); } From the .aspx page public void showScoring(object sender, EventArgs e) { removeLastLoadedControl(); ucScoring.Visible = true; } So, here comes the problem: There are two postbacks taking place when I change the visible attribute of the ucScoring control. The first postback is fine, it's handled by the updatePanel. The second postback is a full postback, and i really don't understand why it is happening. I'm really lost here, please help! Thanks Mat

  • Dynamic editor upload into web page. Need advice

    - by Andrew Florko
    Hello everybody, I am writing intranet site for tracking employees science activities in organization. There lots of editable information on each personal page (science degree, publications & so on) so I upload editor per request (user clicks "edit" and modal dialog with html editor: set of textboxes/comboboxes/autocomplete features & validation logic appears). Editor is html layout that is wrapped with jquery dialog plugin + some logic, written as javascript functions that should be invoked from the callee page (onsubmit, validate, afterLoad editor events). There are also attributes (editor preferrable with and height) that are passed to callee page also. Currently I send these functions & attribute as ... function onsubmit() { }; function validate() { } var width = 640; var height = 800 ... code that is embedded into the request page. Function calls and editor markup wrap with jquery plugin completed in the callee page. It works, but I have some try { call editor event handler } catch { } stuff in callee page (because not every editor provides these functions) and some attributes (editor width & height for instance) that are loaded as variables declared in javascript. Please, suggest, is there a better approach to build & use custom editors for my situation. Thank you in advance!
