• asp.net mvc - limit access to web pages

  - by niao

  Greetings, in my asp.net mvc application what i would like to do is to enable access to some pages only after user was successfully authorized. I have already created custom membership provider and that works fine. How can I, in web config create such rule - for instance for all pages in ~Admin/ folder? I don't want to create on every controller's action the validation code. For now i have in my web.config the following statement: <location path="~/Admin"> <system.web> <authorization> <deny users="?"/> </authorization> </system.web> but it doesn't work.

• Make a USB Device, Control It In Java

  - by yar

  I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well1. Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is there something better suited for communicating with Java? Note: I know that Arduino has something to do with Java (not sure what), but it seems like code must be written in a subset of C. How would I get moving on this topic? 1 - No laughter, please.

• Load all tab bar views when application first runs

  - by codenoobie

  Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

• Writing a simple incrementer counter in rails

  - by Trip

  For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  Hello, am a newbie in ruby on rails and am stuck with a simple problem of routing. I have my controller 'sub' and the 'Views' folder containing the add,edit,new erb files. In my routes file, i have 'map.resources :subs'. Until now, everything is fine. Problem: I moved the add,edit,new erb files into a subfolder called 'admin' inside the 'Views' main directory. I have no idea how to call those erb files from that 'admin' subdir. By default, it is looking for /app/views/subs/index.html.erb, and i want it to look in /app/views/subs/admin/index.html.erb Please can anyone tell me how to do this. Many many thanks

• How do I use link_to_remote to pass then render a partial in rails?

  - by Angela

  I want to create several link_to_remote links that are campaign names: <% @campaigns.each do |campaign| %> <!--link_to_remote(name, options = {}, html_options = nil)--> <%= link_to_remote(campaign, :update => "campaign_todo", :url => %> <% end %> I want the output to update on the page to render a partial, which runs a loop through the values associated with the campaign. The API docs says this will render a partial, but I'm not clear where the name of the :partial template is passed in, either here or in the controller Thanks.

• Rails: Link changes one attribute and then goes back

  - by James

  Rails newbie here. I have a list of items which can have a status represented by an integer (right now its just 1=active 0=inactive). What I want is next to each item a link to change the status of that item. So it might look like this: A nice item - Enable Another pretty item - Disable I can't think of how to make the link work. I just want a user to click the link and then the page refreshes and the item get updated. This doesn't work: <%= link_to "Enable", :controller => "items", :action => "update", :status => 1 %>

• Need advice on multitab form in ASP.NET MVC

  - by Sasha

  Hi all, i need an advice on how to implement my form. I have a requirement: i need a form that spans through 5 tabs. Each tab has around 10 fields, some of them empty, some of them must contain data from db and be non editable. Each of these tabs must be a part of one form that is submitted to my controller. The question is: what is the best way to implement this? I was thinking about having partial views on each tab, each view would have its own model class. After form gets filled all data from all partials would go to action that will take care of all of it. Any advices? I am using ASP.NET MVC 1, Entity Framework 1, mvc extensions from Telerik and jQuery

• Cannot call struct properties from HAML file

  - by Lander

  I have the following code in my controller: @nav_items = ActiveSupport::OrderedHash.new @nav_items[:home] = Struct::NavItem.new("Home", nil, "/", "icon-home") @nav_items[:about] = Struct::NavItem.new("About", nil, "/about", "icon-heart") @nav_items[:contact] = Struct::NavItem.new("Contact", nil, "/contact", "icon-envelope") if (current_user != nil && current_user.admin?) @nav_items[:admin_divider] = Struct::NavItem.new(nil, "divider-vertical", nil, nil) @nav_items[:admin] = Struct::NavItem.new("Admin", nil, "/admin", "") end And the following in my view: - @nav_items.each do |nav_item| %li{ :class => nav_item[:class] } %a{ :href => nav_item[:link] }= nav_item[:text] And my struct definition: Struct.new("NavItem", :text, :class, :link, :icon_class) I'm relatively new to Ruby, Rails, and HAML, but in another project using ERB rendering, code like that worked fine. I've tried referencing properties by doing something like nav_item.link as well, but that still does not work. The error I get with my current code is: Symbol as array index By using code like nav_item.link: undefined method `link' for #< Array:0x126970ff0 As this is my first time using HAML, I'm not too sure what I'm doing wrong.

• How to set up two models having a has_many association with each other

  - by daz13

  I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject. I think I'm solid on the basics of the set up for each model: for teacher.rb: has_many :subjects for subject.rb: has_many :teachers and the teachers table should have a subject_id column and the subject table should have a teacher_id column. What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject. Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.

• Problem when exiting search in iPhone

  - by camilo

  Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

• Get current user from View

  - by gosu kiwi

  So what I want to do is, in my main layout, have a menu for logged in users, and a different for anon users. THe layout will be used on every page, so I'm not sure how to do this, as I've seen, the Auth Component can only be used in the controller, this would be nice if I had to do this in only one view, but for every view, how can I do this? Do I have to do something on AppController? What I want to do is basically // layout <?php if(logged): ?> Welcome <?php echo $user; ?> <?php else: ?> Welcom anon, Log in? <?php endif; ?>

• Zend Framework: How to handle exceptions in Ajax requests?

  - by understack

  Normally when an exception is thrown, Error controller takes command and displays error page with regular common header and footer. This behavior is not wanted in Ajax request. Because in case of error, whole html page is sent over. And in cases where I'm directly loading the content of http response in a div, this is even more unwanted. Instead in case of Ajax request, I just want to receive 'the actual error' thrown by exception. How can I do this? I think, one dirty way could be: set a var in ajax request and process accordingly. Not a good solution.

  im testing symfony form validation. the problem is very simple. no matter what i put in the body text area and post it, i keep getting "Required" back. i dont know why. i just have one validation rule. here is the code: code what is wrong/how can i debug? thanks UPDATE: it has something to do with the binding in the controller. cause even if i delete the validation the form will still not be valid and it will be passed to the template but this time without the "Required". so it wont be valid no matter if ive got the validation or not. it has something to do with the embedForm() maybe? someone that has validated an embeded form?

• What is the difference between "render a view" and send the response using the Response's method "sendResponse()"?

  - by Green

  I've asked a question about what is "rendering a view". Got some answers: Rendering a view means showing up a View eg html part to user or browser. and So by rendering a view, the MVC framework has handled the data in the controller and done the backend work in the model, and then sends that data to the View to be output to the user. and render just means to emit. To print. To echo. To write to some source (probably stdout). but don't understand then the difference between rendering a view and using the Response class to send the output to the user using its sendResponse() method. If render a view means to echo the output to the user then why sendResponse() exists and vise versa? sendResponse() exactly sends headers and after headers outputs the body. They solve the same tasks but differently? What is the difference?
