  • ASP.NET MVC Actions that return different views, or just make a ton of Actions?

    - by Nate Bross
    So, I am in a situation, where I need to display a different view based on the "Role" that the authenticated user has. I'm wondering which approach is best here: [Authorize(Roles="Admin")] public ActionResult AdminList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } [Authorize(Roles = "Consultant")] public ActionResult ConsultantList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } or should I do something like this [Authorize] public ActionResult List(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); if(HttpContenxt.User.IsInRole("Admin") { return View("AdminList", data ); } if(HttpContenxt.User.IsInRole("Consultant") { return View("ConsultantList", data ); } return View("NotFound"); }

  • Using AJAX to display error message Ruby on Rails

    - by bgadoci
    I have built a blog using Ruby on Rails. New to both. I am implementing AJAX pretty effectively until I get to the error handling portion. I allow for comments on posts and do this by rendering a comment partial and remote form in the /views/posts/show.html.erb page. Upon successful save of a comment the show page is updated using views/comments/create.js.rjs and displays a flash notice. I am simply trying to flash a notice when it doesn't save. Searched around and worked this a bit on my own. Can't get it to fly. Here is my code: /views/posts/show.html.erb <div id="comments"> <%= render :partial => @post.comments %> <div id="notice"><%= flash[:notice] %></div> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area (:body, :class => "textarea") %> </p> <p> <%= f.label :name, "Name" %><br/> <%= f.text_field (:name, :class => "textfield") %> </p> <p> <%= f.label :email, "Email" %><br/> <%= f.text_field (:email, :class => "textfield") %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <div id="comment-wrapper"> <% if admin? %> <div id="comment-destroy"><%=link_to_remote "X", :url => [@post, comment], :method => :delete %></div> <% end %> <%= h(comment.body) %><br/><br/> <div class="small">Posted <%= time_ago_in_words(comment.created_at) %> ago by <%= h(comment.name) %> <% if admin? %> | <%= h(comment.email) %> <% end %></div> </div> <% end %> /views/comments/create.js.rjs page.insert_html :bottom, :comments, :partial => @comment page[@comment].visual_effect :highlight page[:new_comment].reset page.replace_html :notice, flash[:notice] flash.discard CommentsController#create def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| if @comment.save flash[:notice] = "Thanks for adding this comment" format.html { redirect_to @post } format.js else flash[:notice] = "Make sure you include your name and a valid email address" format.html { redirect_to @post } format.js end end end

  • Web-serving a file : Firefix truncates name

    - by interstar
    I'm serving a file from Lighttpd whose name contains space-characters. I'm using mimetype "application/octet-stream" When I download this in Chrome, it works perfectly. But when I download in Firefox, the filename is truncated at the first space. Is this to do with the mimetype? With some other lightty config? Or maybe something to do with the kind of space-character I'm using?

  • Is it possible to redirect non-HTML files with HTTP? And chaining redirects?

    - by Earlz
    Hello, I have been thinking about a neat way of load balancing and one thing that would be required is to be capable of loading an image on an HTML page from multiple locations without rewriting the URL(on each load) So what I need to be able to do is have one URL which is the "static" URL. Such as http://example.com/myimage.png The image is not actually contained in example.com though. So example.com does a either a 302 or 301 or 307 HTTP response to cause a redirect to 2.example.com. How do browsers handle this with images like in this situation? Also, how do browsers handle multiple redirections for instance if 2.example.com also didn't contain it and it went to 3.example.com ? (Note, I am asking this because I've never seen a 301 redirect on anything but an HTML page) Also, which status code would be best to use. 301 means "moved permanently" which this "move" isn't permanent so I don't want it cached. Should I use 307? Is that supported by search engines and modern browsers?

  • RESTful copy/move operations?

    - by ladenedge
    I am trying to design a RESTful filesystem-like service, and copy/move operations are causing me some trouble. First of all, uploading a new file is done using a PUT to the file's ultimate URL: PUT /folders/42/contents/<name> The question is, what if the new file already resides on the system under a different URL? Copy/move Idea 1: PUTs with custom headers. This is similar to S3's copy. A PUT that looks the same as the upload, but with a custom header: PUT /folders/42/contents/<name> X-custom-source: /files/5 This is nice because it's easy to change the file's name at copy/move time. However, S3 doesn't offer a move operation, perhaps because a move using this scheme won't be idempotent. Copy/move Idea 2: POST to parent folder. This is similar to the Google Docs copy. A POST to the destination folder with XML content describing the source file: POST /folders/42/contents ... <source>/files/5</source> <newName>foo</newName> I might be able to POST to the file's new URL to change its name..? Otherwise I'm stuck with specifying a new name in the XML content, which amplifies the RPCness of this idea. It's also not as consistent with the upload operation as idea 1. Ultimately I'm looking for something that's easy to use and understand, so in addition to criticism of the above, new ideas are certainly welcome!

  • validates_uniqueness_of...limiting scope - How do I restrict someone from creating a certain number

    - by bgadoci
    I have the following code: class Like < ActiveRecord::Base belongs_to :site validates_uniqueness_of :ip_address, :scope => [:site_id] end Which limits a person from "liking" a site more than one time based on a remote ip request. Essentially when someone "likes" a site, a record is created in the Likes table and I use a hidden field to request and pass their ip address to the :ip_address column in the like table. With the above code I am limiting the user to one "like" per their ip address. I would like to limit this to a certain number for instance 10. My initial thought was do something like this: validates_uniqueness_of :ip_address, :scope => [:site_id, :limit => 10] But that doesn't seem to work. Is there a simple syntax here that will allow me to do such a thing?

  • How to organise a php based website

    - by bsandrabr
    I am putting my php /mysql website up and this is my scenario The users are grouped into sites each site with their own unique database. There will be about 40 users per site. the two options I'm trying to decide between are have a central website running the php and directing the users off to their own database using sub domains for each user each with their own php in htdocs I dont even know if 2 is possible/stupid but if it was, would it make any difference to performance as they're all being run by the same server. Any other ideas/ advice much appreciated as I want to organise it the best way from the start

  • How to reference an anonymous JavaScript function?

    - by ProfK
    I'm trying to call a Page Method using a jQuery 'attached' event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several 'error' functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions? $(":button").click(function () { var button = this; PageMethods.DoIt( function (a, b, c) { alert(button); }); }); This example passes an anonymous function for the success callback. There is only one of these. If I was passing an error callback, how could I use 'function (e, c, t)' for all 3 error callbacks?

  • Web-based code interpreter

    - by detly
    I remember coming across a website where I could type in some code and it would compile and run it (or error out), displaying any console output. It accepted a variety of interpreted and non-interpreted languages — I specifically remember that I could use C (maybe Python too... I'm not completely sure). Does anyone know what site I'm talking about?

  • Using font in site

    - by Misha Moroshko
    I know that I can use fonts like arial "for free". But what if I want to use not a standard font ? Is that something that a browser should support ? Where I can check, for example, which fonts Firefox 3.6.3 supports ? I would like, for example, to change the font of input text area.

  • Is Webhooks a style/pattern or a specification?

    - by Emilio
    I've been reading about Webhooks and I'm trying to determine if it's a specification vs a style/pattern. By "specification" I mean that the implementation details, e.g. headers, payload and so on are well defined. By "style" or "pattern" I mean in the sense that REST is a style (as opposed to a spec) or a pattern which describes usage but doesn't define implementation details. From what I see, Webhooks is a style/pattern. That the event(s) which triggers the http callbacks are generated however the developer wants, and that the http callbacks have no specific implementation requirements except to be an http post. Is this correct?

  • Programmatically access currency exchange rates

    - by Adam Pierce
    I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars. Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ? UPDATE: I have now written a PHP class which implements this. You can get the code from my website.

  • An image from byte to optimized web page presentation

    - by blgnklc
    I get the data of the stored image on database as byte[] array; then I convert it to System.Drawing.Image like the code shown below; public System.Drawing.Image CreateImage(byte[] bytes) { System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(bytes); System.Drawing.Image image = System.Drawing.Image.FromStream(memoryStream); return image; } (*) On the other hand I am planning to show a list of images on asp.net pages as the client scrolls downs the page. The more user gets down and down on the page he/she does see the more photos. So it means fast page loads and rich user experience. (you may see what I mean on www.mashable.com, just take care the new loads of the photos as you scroll down.) Moreover, the returned imgae object from the method above, how can i show it in a loop dynamically using the (*) conditions above. Regards bk

  • Checkbox vs Two Radio Buttons - Which one is more usable?

    - by Engram
    I'm currently working on some setting screens, most of which contain a 2 column form with a preference question on the left, and a form element on the right. The questions are things like: Can add/edit other users? Can delete clients? Obviously this setting is a binary setting and most UI "experts" would insist that a checkbox is the appropriate form element to use. However, when I mocked up the form with the checkboxes it looked unfriendly and it seemed hard to relate the state of the checkbox back to the question. I changed the form to use two radio buttons instead: Yes o No Personally I find this easier to process, as the options are actually answers to the question posed on the left. In terms of clicking it makes no difference to the user, it's a single click each time to change the setting. What do you think of this use of radio buttons? Is this better or worse than a checkbox and why?
