  • Simple search only searching last word of record

    - by bennett_an
    I set up a simple search as instructed in part of railscast #240. in controller @reports = Report.search(params[:search]).order('created_at DESC').paginate(:page => params[:page], :per_page => 5) in model def self.search(search) if search where('apparatus LIKE ?', "%#{search}") else scoped end end in view <%= form_tag reports_path, :method => :get do %> <p> <%= text_field_tag :search, params[:search] %> <%= submit_tag "Search", :name => nil %> </p> <% end %> it all works... but... I have a few records for example, one with "another time test" and another with "last test of time" if i search "test" the first comes up but the second doesn't, and if i search "time" the second comes up but not the first. It is only seeing the last word of the record. what gives?

  • Sinatra: rendering snippets (partials)

    - by Michael
    I'm following along with an O'Reilly book that's building a twitter clone with Sinatra. As Sinatra doesn't have 'partials' (in the way that Rails does), the author creates his own 'snippets' that work like partials. I understand that this is fairly common in Sinatra. Anyways, inside one of his snippets (see the first one below) he calls another snippet text_limiter_js (which is copied below). Text_limiter_js is basically a javascript function. If you look at the javascript function in text_limiter_js, you'll notice that it takes two parameters. I don't understand where these parameters are coming from because they're not getting passed in when text_limiter_js is rendered inside the other snippet. I'm not sure if I've given enough information/code for someone to help me understand this, but if you can, please explain. =snippet :'/snippets/text_limiter_js' %h2.comic What are you doing? %form{:method => 'post', :action => '/update'} %textarea.update.span-15#update{:name => 'status', :rows => 2, :onKeyDown => "text_limiter($('#update'), $('#counter'))"} .span-6 %span#counter 140 characters left .prepend-12 %input#button{:type => 'submit', :value => 'update'} text_limiter_js.haml :javascript function text_limiter(field,counter_field) { limit = 139; if (field.val().length > limit) field.val(field.val().substring(0, limit)); else counter_field.text(limit - field.val().length); }

  • My UITextView delegate method doesn't respond

    - by user611967
    Hi guys. I would like to start we that i'm not a very good english speaker, so excuse me if something is wrong. So I have this code header file : import @interface macViewController : UIViewController { UINavigationItem *navItem; UITextView *iTextView; } @property (nonatomic, retain) IBOutlet UINavigationItem *navItem; @property (nonatomic, retain) IBOutlet UITextView *iTextView; (IBAction) btnClicked; @end implementation file : import "macViewController.h" @implementation macViewController @synthesize navItem, iTextView; (IBAction) btnClicked { if (self.editing == YES) { self.editing = NO; [iTextView resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Data Saved" message:@"Your data was saved" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; } else { self.editing = YES; [iTextView becomeFirstResponder]; } NSLog(@"works"); self.navItem.rightBarButtonItem = self.editButtonItem; self.navItem.rightBarButtonItem.action = @selector(btnClicked); } (void) textViewDidChangeUITextView *)textView { NSLog(@"works"); } So like you guess it's a view based app wich when i tap Edit button the keyboard pops-up then i press Done button and keyboard disappear and appear a alert view.

  • CakePHP: Missing database table

    - by Justin
    I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

    so I am trying to draw some grid lines that in landscape go all the way down to the bottom, however when I switch to landscape the the graph doesn't follow and the grid lines go smaller.

  • Page does update with details from the database after i hit a button

    - by swathi
    I have a code and the way it should work is,when they click on NEW CUSTOMER,it takes them to test1.php where in they enter the details and they hit submit.it saves all the details in properly in the database and when i go back and hit REFRESH ,it should come up with the customer details which they had entered in previously. But what happens is, when i click on the REFRESH,it refreshes the same old page which is empty.I wanted to find out where am i missing the logic.Thanks in advance. The sample code would be <tr> <td class="tdvisitbig" colspan="5">THIS IS A TEST</td> </tr> <tr> <td class='tdvisitbig' colspan="5"><input type="button" onClick="openVisit('test1.php?id=<?=$key?>&name=<?=$name?>');return false;" value="NEW CUSTOMER" class="submit">&nbsp;<input type="button" value="REFRESH" name="add_xyz" class="submit" onClick="document.add.target='_self';document.add.action='test3.php?redirect=visit&section=test page';document.add.submit();"></td> </tr> <? $q = "SELECT address,customernum,status FROM customer WHERE name='$name' ORDER BY customernum"; $r = mysql_query( $q , $Link ); while( $rw = mysql_fetch_assoc( $r ) ) { extract( $rw ); ?> <tr> <? } ?>

  • One Common View In Every ViewController

    - by l3v
    I am having a hard time wording this when searching the internet so I am just going to ask the question. I have an options view in my app that slides into view when the user clicks a button. This options view will display app information like settings. I want this options view to be displayed on every view controller in my app. I do not want to copy and paste the code for the options view into every viewcontroller file. The options view has quite a few outlets and actions and also calls many delegates. How can I reuse this options view in all my view controllers without adding all the outlets, actions, and delegate methods each time? I was going to make a new file with public methods, but I would still have to copy the outlets. Would this public methods file have to include delegate methods as well then? Let me know if my question does not make sense. I am hoping there is a standard way of implementing something like this.

  • Parallelizing for loop

    - by vman049
    I have MATLAB code which I'm trying to parallelize with a simple change from "for" to "parfor." I'm unable to do so because of an error I'm receiving on the variable "votes" which states: Valid indices for 'votes' are restricted in PARFOR loops. Explanation: For MATLAB to execute parfor loops efficiently, the amount of data sent to the MATLAB workers must be minimal. One of the ways MATLAB achieves this is by restricting the way variables can be indexed in parfor iterations. The indicated variable is indexed in a way that is incompatible with parfor. Suggested Action: Fix the indexing. For a description of the indexing restrictions, see “Sliced Variables” in the Parallel Computing Toolbox documentation. Below is my code: votes = zeros(num_layers, size(spikes, 1), size(SVMs_layer1, 1)); predDir = zeros(size(spikes, 1), 1); chronProb = zeros([num_layers, size(chronDists)]); for i = 1:num_layers switch i case 1 B = B1; k_elem_temp = k_elem1; rest_elem_temp = rest_elem1; case 2 B = B2; k_elem_temp = k_elem2; rest_elem_temp = rest_elem2; case 3 B = B3; k_elem_temp = k_elem3; rest_elem_temp = rest_elem3; end for j = 1:length(chronPred) if chronDists(i, j, :) ~= 0 parfor k = 1:8 chronProb(i, j, k) = logistic(B{k}(1) + chronDists(i, j, k).*(B{k}(2))); votes(i, j, k_elem_temp(k, :)) = votes(i, j, k_elem_temp(k, :)) + chronProb(i, j, k)/num_k(i)/num_layers; votes(i, j, rest_elem_temp(k, :)) = votes(i, j, rest_elem_temp(k, :)) + (1 - chronProb(i, j, k))/num_rest(i)/num_layers; end end end end Do you have any suggestions as to how I could adjust my code so that it runs in parallel? Thank you!

  • How do I code a tree of objects in Haskell with pointers to parent and children?

    - by axilmar
    I've got the following problem: I have a tree of objects of different classes where an action in the child class invalidates the parent. In imperative languages, it is trivial to do. For example, in Java: public class A { private List<B> m_children = new LinkedList<B>(); private boolean m_valid = true; public void invalidate() { m_valid = false; } public void addChild(B child) { m_children.add(child); child.m_parent = this; } } public class B { public A m_parent = null; private int m_data = 0; public void setData(int data) { m_data = 0; m_parent.invalidate(); } } public class Main { public static void main(String[] args) { A a = new A(); B b = new B(); b.setData(0); //invalidates A } } How do I do the above in Haskell? I cannot wrap my mind around this, since once I construct an object in Haskell, it cannot be changed. I would be much obliged if the relevant Haskell code is posted.

  • How do I get a reference to a rootViewController to a sub-view?

    - by Andy
    An answer posted for one of my previous questions brings up another question; I am calling a new view controller, "RuleBuilder," from my rootViewController. The rootViewController holds a reference to a contacts array. How do I get a reference to that array into the RuleBuilder? I tried adding UITableViewController *rootViewController; ... @property (nonatomic, retain) UITableViewController *rootViewController; to RuleBuilder.h, and then @synthesize rootViewController; in RuleBuilder.m. When I instantiate and push the RuleBuilder from within rootViewController, I do this: ruleBuilder.rootViewController = self; But when I try this [rootViewController.contacts addObject:newContact]; from within RuleBuilder, I get a compiler error to the effect of "request for 'contacts' in something not a struct" (or very similar; I haven't implemented this exact snippet of code, but I tried an identical approach not an hour ago for a couple of different references that I never was able to get working). Thanks, again, for your help.

  • Very weird jquery/json problem...

    - by Scarface
    Hey guys I have finally located the cause of this problem...I just have no idea how to fix it and why it is happening. I have a jquery getjson function and it returns 0 results every 2-5 clicks on new topics or refreshes. For some reason if I change my query to sort results by ASC it always returns results and much quicker, but this poses a problem since I need results by DESC. If anyone has any ideas, I would greatly appreciate it because I am dumbfounded at this point. Here is my query but I need it by DESC SELECT time, user, message FROM comments WHERE topic_id='$topic_id' ORDER BY time ASC LIMIT 10 $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } }); I return results like so while($row = mysql_fetch_array($res)){ $data[] = $row; } $out = json_encode($data); print $out;

  • Create Rails model with argument of associated model?

    - by Kyle Carlson
    I have two models, User and PushupReminder, and a method create_a_reminder in my PushupReminder controller (is that the best place to put it?) that I want to have create a new instance of a PushupReminder for a given user when I pass it a user ID. I have the association via the user_id column working correctly in my PushupReminder table and I've tested that I can both create reminders & send the reminder email correctly via the Rails console. Here is a snippet of the model code: class User < ActiveRecord::Base has_many :pushup_reminders end class PushupReminder < ActiveRecord::Base belongs_to :user end And the create_a_reminder method: def create_a_reminder(user) @user = User.find(user) @reminder = PushupReminder.create(:user_id => @user.id, :completed => false, :num_pushups => @user.pushups_per_reminder, :when_sent => Time.now) PushupReminderMailer.reminder_email(@user).deliver end I'm at a loss for how to run that create_a_reminder method in my code for a given user (eventually will be in a cron job for all my users). If someone could help me get my thinking on the right track, I'd really appreciate it. Thanks!

  • Accessing global variables in a flash[:notice]

    - by Trip
    This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global. I need that contional statement back, as I'm pretty sure its responsible for actually adding the new @deal . So I assume my syntax is off. Do note, I added an extra 'end' when I uncomment this block. def create -# This will use the disclaimer_ids submitted from the check boxes in the view -# to add/delete deal.disclaimers entries to matched the list of checked boxes. @deal = Deal.new(params[:deal]) -# <------I Need this commented out IF statement back ------- -#if @deal.valid? && @organization.deals << @deal flash[:notice] = 'Your promotion is published!

  • How do I use has_many :through and in_place_edit?

    - by Angela
    I have two Models: Campaign and Contact. A Campaign has_many Contacts. A Contact has_many Campaigns. Currently, each Contact has a contact.date_entered attribute. A Campaign uses that date as the ate to count down to the different Events that belong_to the Campaign. However, there are situations where a Campaign for a specific Contact may need to be delayed by X number of days. In this instance, the campaigncontact.delaydays = 10. In some cases, the Campaign must be stopped altogether for the specific Contact, so for now I set campaigncontact.delaydays = 1. (Are there major problems with that?) By default, I am assuming that no campaigncontact exists (but not sure how that works?) So here's what I've tried to do: class Contact < ActiveRecord::Base has_many :campaigncontacts has_many :campaigns, :through => :campaigncontacts end class Campaign < ActiveRecord::Base has_many :campaigncontacts has_many :contacts, :through => :campaigncontacts end script/generate model campaigncontact campaign_id:integer contact_id:integer delaydays:integer class Campaigncontact < ActiveRecord::Base belongs_to :campaign belongs_to :contact end So, here's the question: Is the above correct? If so, how do I allow a user to edit the delay of a campaign for a specific Contact. For now, I want to do so from the Contact View. This is what I tried: In the Contact controller (?) in_place_edit_for :campaigncontact, column.delaydays And in the View <%= in_place_editor_field :campaigncontact, :delaydays %> How can I get it right?

  • How can I create dynamically updated views in a tab bar view, based on settings selection?

    - by Diggers
    Hi all, Noob question.... I've created a Tab Bar application. It has four tabs and works fine. Each view is created with a XIB and is effectively static. Each view takes user input and responds on screen. What I need to be able to do is change the input options the user have - in effect remove some UITextFields dependant upon which option the user selects in settings. I've created root.plist and created settings no problem i've also created additional XIBS for the altered UI, but what I don't know how to do, is call these into the tab view controller on demand. Effectively tab one has 3 possible views, tab two 3 possible views etc. But I only want the one that's relevant for the users settings selction to be displayed? Make sense? For reference, if we call the different views - UIInputViewA1, ...A2,....A3 UIInputViewB1,....B2....B3 etc. Hope someone can help, been trawling the net for nights trying to get my head round this. Beggining iPhone Development Bible doesn't help either. If you need any more info, please shout. Cheers Paul.

  • ASP.NET MVC: How to show value in a label from selected Drop Down List item?

    - by Lillie
    Hi! I'm trying to show a value of selected Drop Down List item in a label. I managed to make this work with Web Forms but with MVC I'm totally lost. My Index looks like this: [...] <% using (Html.BeginForm()) { %> <table> <tr> <td>Processor</td> <td><%= Html.DropDownList("lstProcessor1", new SelectList((IEnumerable)ViewData["Processor1List"], "product_price", "product_description")) %></td> </tr> <tr> <td>Total Amount</td> <td>0,00 €</td> </tr> </table> <input type="submit" value="Submit" /> <% } %> [...] And my HomeController starts with: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Mvc.Ajax; using MvcApplication1.Models; namespace MvcApplication1.Controllers { [HandleError] public class HomeController : Controller { // Connect database DB50DataContext _ctx = new DB50DataContext(); // GET: /Home/ public ActionResult Index() { // Search: Processors var products = from prod in _ctx.products where prod.product_searchcode == "processor1" select prod; ViewData["Processort1List"] = products; return View(); } I would like the product_price to show on the second line of the table, where it now says 0,00 €. It should also update the price automatically when the item from the Drop Down List is changed. I guess I should use JQuery but I have no idea how. Could someone please give me some tips how to do this?

  • jQuery jPicker colorpicker: How to convert from 8 digit (w Transparency) to standard 6 digit hex?

    - by Scott B
    I've got a jPicker installed and running fine; its a pretty sweet script. However, the value it returns to my input box is 8 digit hex. I need it to return 6 digit hex. Rather than post-process the 8 digit into 6, I'd rather just hack into the script and force 6 digit. Alternately, I'd be ok with hooking into the change event of the jPicker to intercept the value its sending to the input element and doing the conversion there just before it updates the input with the hex. Here's my code: $(function() { $('#myThemeColor').jPicker(); /* Bind jPicker to myThemeColor input */ $("#carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev", visible: 6, speed: 700 }); And here's the code I'm working with to intercept the myThemeColor input's change event, but its not firing at all. $('#myThemeColor').change(function() { alert(this.val()); /* does not fire on any action */) if($(this).val().length == 8) { $(this).val(function(i, v) { return v.substring(0, 6); }); } });
