  • How to programatically set cell.textLabel.text from a different view?

    - by Andy
    I've got a view controller, call it VC1, that's a table view. When I tap a cell in the table view, I am presented with a new view controller, call it VC2, which is a short list of choices. After making a choice, I want to dismiss VC2 and set the cell.textLabel.text property of the VC1 cell I originally tapped to the value I selected in VC2. Conceptually speaking, what is the proper way to do this? I've tried a handful of different approaches, but all of them seem wonky at best, and only one of them actually worked - although it was the most cumbersome of all, passing references to both view controllers and table view cells and all kinds of things. It just feels like I'm making a mountain out of what is probably a mole hill. This is such a common paradigm that I find it hard to believe there's not a simple method for doing it. Thanks in advance for any input you can offer.

  • java multipart POST library

    - by tom
    Is there a multipart POST library out there that achieve the same effect of doing a POST from a html form? for example - upload a file programmingly in Java versus upload the file using a html form. And on the server side, it just blindly expect the request from client side to be a multipart POST request and parse out the data as appropriate. Has anyone tried this? specifically, I am trying to see if I can simulate the following with Java The user creates a blob by submitting an HTML form that includes one or more file input fields. Your app sets blobstoreService.createUploadUrl() as the destination (action) of this form, passing the function a URL path of a handler in your app. When the user submits the form, the user's browser uploads the specified files directly to the Blobstore. The Blobstore rewrites the user's request and stores the uploaded file data, replacing the uploaded file data with one or more corresponding blob keys, then passes the rewritten request to the handler at the URL path you provided to blobstoreService.createUploadUrl(). This handler can do additional processing based on the blob key. Finally, the handler must return a headers-only, redirect response (301, 302, or 303), typically a browser redirect to another page indicating the status of the blob upload. Set blobstoreService.createUploadUrl as the form action, passing the application path to load when the POST of the form is completed. <body> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> </body> Note that this is how the upload form would look if it were created as a JSP. The form must include a file upload field, and the form's enctype must be set to multipart/form-data. When the user submits the form, the POST is handled by the Blobstore API, which creates the blob. The API also creates an info record for the blob and stores the record in the datastore, and passes the rewritten request to your app on the given path as a blob key.

  • Problem adding UIBarButtonItems to a ToolBar

    - by Olivier de Jonge
    I have a UINavigationController with a UITableViewController in it. I want to show a ToolBar on the bottom with UIBarButtonItem's. The ToolBar is showing up, but the buttons won't appear. Anyone knows why? - (void)viewDidLoad { [super viewDidLoad]; [[self navigationItem] setTitle:@"Selections List"]; [[self navigationItem] setRightBarButtonItem:[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addProjectSearch:)] autorelease]]; [[self navigationItem] setLeftBarButtonItem:[self editButtonItem]]; [[super tableView] setDataSource: self]; [[super tableView] setDelegate: self]; //Toolbar UIBarButtonItem * logoutButton = [[[UIBarButtonItem alloc] initWithTitle:@"Log out" style:UIBarButtonItemStylePlain target:self action:@selector(logOut:)]autorelease]; NSMutableArray * arr = [NSMutableArray arrayWithObjects:logoutButton, nil]; [[self navigationController] setToolbarHidden: NO animated:YES]; [[self navigationController] setToolbarItems:arr animated:YES]; }

  • zend_acl: Adding extra resources dynamically and getting a param predispatch

    - by Timmeh
    First sorry about the woffle as I'm not sure how best to describe this. Basically I am not sure how I can get param in the bootstrap before the controller is loaded, but here is the long winded version... I have got an acl class storing all my default resources in. All my page/post content is a database and I want the admin the ability to choose who which role the page would become available. I know it is possible just to loop through the database table and add them all in at once, but I am concerned that this is a drain on resources. I have it working whereby my access check plugin can call a dynamic permission function, but I need to get the parameter of the current page ID and it's permission to set it before the controller is loaded. Does that make sense or am I worry over nothing and I should just get the resources of all the pages at once? thanks in advance for reading my garble!!

  • rails expiring cache

    - by ash34
    Hi, I entered some products data into a table using a migration. I need to expire the page and fragment cache when I update, add, delete products from this table. I created a sweeper for this. class ProductSweeper < ActionController::Caching::Sweeper observe Product def after_create expire_cache end def after_save expire_cache end def after_update expire_cache end def after_destroy expire_cache end private def expire_cache expire_page(:controller => 'ProductsController', :action => 'index') expire_fragment 'listed_products' end end Then in script/console I update the product name and saved. When I reload my app in the browser it still gives me a cache hit. Cached fragment hit: views/listed_products (0.2ms) Can someone tell me how to expire this cache. I will not be adding, updating, deleting products through a controller action. thanks, ash

  • Problem with asp.net mvc route not firing when in <script> tag

    - by Chev
    I cannot get the following route to fire when a url is requested from a script tag. I have the following route: // maps to "/cache/cachecontent/JavaScriptInclude/1/javascript" routes.MapRoute( null, "cache/{action}/{key}/{version}/{type}", new { controller = "Cache", action = "CacheContent", key = "", version = "", type = "" } ); I have a javascript script tag like: <script type="text/javascript" src="/cache/cachecontent/JavaScriptInclude/1/javascript" /> Yet the route is not firing and the controller is not instantiated. If i drop the url into the address bar of the browser all is fine, but is not triggered from the javascript tag? Any ideas?

  • Is it possible to register a user and submit a comment with one form with Wordpress?

    - by zack
    Is it possible to do both registering for an account and submit a comment at the same time? I want the user to be able to do this all on one page to ecourage the registration rather than be discouraged about typing something, not realizing they had to be registered and thus having to leave the page. I think that this could be done by adding register user action to the submit comment action, but not sure how to do it with the prebuilt wordpress add_action or do_action functions. Has anyone tried this, or know of any plug-ins that do this already? I searched but couldn't find anything helpful. Thanks.

  • In XAML is there way to bind key press and key release to specific commands?

    - by Ashley Davis
    In my application I have keys that bound to commands using the KeyBinding class. The command is executed when the key is pressed and released. I have a special case where I want to bind separate commands to the pressed action and to the released action. For example when the space key is pressed I want my app to run a command to enter a special mode. Then when the space key is released I want to run another command to exit that special mode. Currently I do this by manually handling the KeyUp and KeyDown events. Is there anyway to execute commands for pressed and released purely in XAML?

  • Creating a foreign key in MySQL produces error:

  • iphone: Accessing Code for Elements Created in Interface Builder

    - by user362685
    I am attempting to create a basic tab-bar application using interface builder. I create a new project in Xcode selecting tab bar application. My question is how can I access the code that instantiates and pushes each of the views when the tab bar buttons are pressed? I would imagine that would be done by the tab bar controller, however when I write the class file from interface builder (filewrite class files), it just creates a blank generic TabBarController.h/TabBarController.m without the methods for pushing each of the views associated with the tab bar elements. I ask this because I would like to pass each view controller a reference to the data model when they are instantiated. Any help would be greatly appreciated, thanks.

  • Navigation Within TabController

    - by David.Chu.ca
    I am trying to use UITabController as may controller in my main window and add navigation controllers to some tab bar items. For example, the first tab has a navigation controller with table view: ![alt text][1] The SettingsViewController is associated with its own NIB file, where a table view is defined. Within that xib file, I have a table view and set it to the outlet of SettingsViewController class property myTableView. The problem is that in the main xib file, for the SettingsViewController navigation, there is one outlet myTableView. I am not sure if I have to set this to somewhere? The exception I get is "[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsViewController" nib but the view outlet was not set." [1]:

  • Combined sign in and registration page?

    - by Ryan
    This is somewhat against rails convention but I am trying to have one controller that manages both user session authentication and user registration. I am having troubles figuring out how to go about this. So far I am merging the User Controller and the Sessions Controller and having the 'new' method deliver both a new usersession and a new user instance. With the new routes in rails 3 though, I am having trouble figuring out how to generate forms for these items. Below is the code: user_controller.rb class UserController < ApplicationController def new @user_session = UserSession.new @user = User.new end def create_user @user = User.new(params[:user]) if @user.save flash[:notice] = "Account Successfully Registered" redirect_back_or_default signup_path else render :action => new end end def create_session @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default login_path else render :action => new end end end views/user/new.html.erb <div id="login_section"> <% form_for @user_session do |f| -%> <%= f.label :email_address, "Email Address" %> <%= f.text_field :email %> <%= f.label :password, "Password" %> <%= f.text_field :password %> <%= f.submit "Login", :disable_with => 'Logining...' %> <% end -%> </div> <div id="registration_section"> <% form_for @user do |f| -%> <%= f.label :email_address, "Email Address" %> <%= f.text_field :email %> <%= f.label :password, "Password" %> <%= f.text_field :password %> <%= f.label :password_confirmation, "Password Confirmation" %> <%= f.text_field :password_confirmation %> <%= f.submit "Register", :disable_with => 'Logining...' %> <% end -%> </div> I imagine I will need to use :url = something for those forms, but I am unsure how to specify. Within routes.rb I have yet to specify either Usersor UserSessions as resources (not convinced that this is the best way to do it... but I could be). I would like, however, the registration and login on the same page and have implemented this by doing the following: routes.rb match 'signup' => 'user#new' match 'login' => 'user#new' What's the best way to go about solving this?

  • Does to_json require parameters? what about within rails?

    - by Harry Wood
    Does to_json require parameters? what about within rails? I started getting the error "wrong number of arguments (0 for 1)" when doing myhash.to_json Unfortunately I'm not sure when this error started happening, but I guess it relates to some versions of either rails or the json gem. I suppose my code (in a rails controller) is using the ActiveSupport::JSON version of to_json, rather than the to_josn method supported by the json gem. ActiveSupport::JSON vs JSON In environment.rb I have RAILS_GEM_VERSION = '2.3.2' and also config.gem "json", :version=> '1.1.7' It's just a simple hash structure containing primitives which I want to convert in my controller, and it was working, but now I can't seem to run to_json without passing parameters.

  • spring json writes more json then i want

    - by mkoryak
    I am using the json spring view in order to return a simple JSON object from my controller. The problem is that its returning more data then i want. it is returning the validation errors and things inside of my model when all i am doing is this in the controller: Map model = new HashMap() model.put("success", "true"); return new ModelAndView("jsonView", model); If you look at the bottom of this page in the docs it looks like i am getting back data that POST would return. i am not doing a post, i am doing a GET by going directly to the URL with params. How do i get this lib to return just the data in my model?

  • MVC without ORM is not real MVC?

    - by ajsie
    at the moment im integrating ORM (doctrine) into a MVC framework (codeigniter). then it hit me that this was the obvious way of setting up a MVC: the controller calls the models that are representing database tables. look at this picture: MVC + ORM then i wondered, how can a MVC without ORM be real MVC? cause then the models are not real objects, rather aggregations of different functions that perform CRUD, then returning the result to the controller. and there is no need for a state (object properties) i guess so the functions would be all static? correct me if im wrong on this one. i guess a lot of people are using models without ORM. please share your thoughts. how do your models look like?

  • Obtain the pathName dinamically for ASP.NET MVC

    - by vikitor
    Hello, I'm looking for a solution that allows me to get the parent page pathname from a partialView invoked. For example I have an Action baa and a controller boo so the javascript to obtain this will be window.location.pathname, and it returns /boo/baa. The thing is that I use a partial view, so when I try to retrieve the pathname via the URL helper, what I obtain is the PartialView one, and what I need is the pathname for the action that invokes it. I want to do this because I want to show certain things of the partial view depending on the pathname of the parent view that invokes it. Is there a way to do this with ASP.NET MVC? Thank you all in advance,

  • Mongoid Embeds_many won't save on nested form

    - by Brandon J McKay
    I've got an embeds_many association I'm trying to set up which I've done successfully before, but I'm trying to do it all in one nested form and I can't figure it out. Let's say we have a pocket model: class Pocket include Mongoid::Document field :title, type: String embeds_many :coins, cascade_callbacks: true end and a Coin Model: class Coin include Mongoid::Document field :name, type: String embedded_in :pocket end in my form for the pocket, I'm using: = f.fields_for @pocket.coins do |coin| = coin.text_field :name My controller is the default scaffolded controller. When I use the console, it saves fine and I can see the new pocket and coin I've created. But when I try to create or update a coin from the form, the pocket saves but the coin remains unchanged. What am I missing here?

  • Searching in Ruby on Rails - How do I search on each word entered and not the exact string?

    - by bgadoci
    I have built a blog application w/ ruby on rails and I am trying to implement a search feature. The blog application allows for users to tag posts. The tags are created in their own table and belong_to :post. When a tag is created, so is a record in the tag table where the name of the tag is tag_name and associated by post_id. Tags are strings. I am trying to allow a user to search for any word tag_name in any order. Here is what I mean. Lets say a particular post has a tag that is 'ruby code controller'. In my current search feature, that tag will be found if the user searches for 'ruby', 'ruby code', or 'ruby code controller'. It will not be found if the user types in 'ruby controller'. Essentially what I am saying is that I would like each word entered in the search to be searched for, not necessarily the 'string' that is entered into the search. I have been experimenting with providing multiple textfields to allow the user to type in multiple words, and also have been playing around with the code below, but can't seem to accomplish the above. I am new to ruby and rails so sorry if this is an obvious question and prior to installing a gem or plugin I thought I would check to see if there was a simple fix. Here is my code: View: /views/tags/index.html.erb <% form_tag tags_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search], :class => "textfield-search" %> <%= submit_tag "Search", :name => nil, :class => "search-button" %> </p> <% end %> TagsController def index @tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5 @tagsearch = Tag.search(params[:search]) @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 100) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tags } end end Tag Model class Tag < ActiveRecord::Base belongs_to :post validates_length_of :tag_name, :maximum=>42 validates_presence_of :tag_name def self.search(search) if search find(:all, :order => "created_at DESC", :conditions => ['tag_name LIKE ?', "%#{search}%"]) else find(:all, :order => "created_at DESC") end end end

  • Trying to get JQuery Autocomplete working on Asp.Net page.

    - by JasonMHirst
    Can someone shed some light on the problem please: I have the following: $(document).ready(function () { $("#txtFirstContact").autocomplete({url:'http://localhost:7970/Home/FindSurname' }); }); On my Asp.Net page. The http request is a function on an MVC Controller and that code is here: Function FindSurname(ByVal surname As String, ByVal count As Integer) Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT ConSName FROM tblContact WHERE ConSName LIKE '" & surname & "%'" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Contact") sqlConnection.Close() Dim contactsArray As New List(Of String) For Each dr As DataRow In ds.Tables("Contact").Rows contactsArray.Add(dr.Item("ConSName")) Next Return Json(contactsArray, JsonRequestBehavior.AllowGet) End Function As far as I'm aware, the Controller is returning JSON data, however I don't know if the Function Parameters are correct, or indeed if the format returned is interprettable by the AutoComplete plugin. If anyone can assist in the matter I'd really appreciate it.

    More specifically my problem is if I include a pdf in my project and set its build action to content so it gets copied to the server when I publish, is there a way to exclude it from visual studios search and replace feature. Would a post build action be a solution to this? I just don't want anybody to do a global search and replace in my project and mess up the pdfs... I know I just said a mouth full so let me know if you need clarification. Thanks!!!
