  • Deploying Django at Dreamhost

    - by Imran
    I'm trying to get the Poll tutorial working at my Dreamhost account (I don't have any prior experience of deploying Django). I downloaded the script I found here (http://gabrielfalcao.com/2008/12/02/hosting-and-deploying-django-apps-on-dreamhost/) at my home directory and executed it. Now I have Python 2.5 and Django in ~/.myroot/ and my Django projects directory is ~/projects/ Here's the content of ~/projects/ directory (I copied the polls/ and and templates/polls/ directories myself). projects/ |-- admin_media -> /home/imran2140/.myroot/usr/lib/python2.5/site-packages/django/contrib/admin/media |-- dispatch.fcgi |-- polls | |-- __init__.py | |-- __init__.pyc | |-- admin.py | |-- admin.pyc | |-- models.py | |-- models.pyc | |-- polls.db | |-- urls.py | |-- urls.pyc | |-- views.py | `-- views.pyc |-- script_templates | |-- dispatch.template | `-- htaccess.template `-- templates `-- polls |-- detail.html |-- index.html `-- results.html 5 directories, 17 files Now what should I do to get the Polls app working? Update I finally got a "Hello World" Django app working with Passanger WSGI. It worked fine with both Server's default Python 2.3.5 and my installed Python 2.5.2.

  • Brighton Rocks: UA Europe 2011

    - by ultan o'broin
    User Assistance Europe 2011 was held in Brighton, UK. Having seen Quadrophenia a dozen times, I just had to go along (OK, I wanted to talk about messages in enterprise applications). Sadly, it rained a lot, though that was still eminently more tolerable than being stuck home in Dublin during Bloomsday. So, here are my somewhat selective highlights and observations from the conference, massively skewed towards my own interests, as usual. Enjoyed Leah Guren's (Cow TC) great start ‘keynote’ on the Cultural Dimensions of Software Help Usage. Starting out by revisiting Hofstede's and Hall's work on culture (how many times I have done this for Multilingual magazine?) and then Neilsen’s findings on age as an indicator of performance, Leah showed how it is the expertise of the user that user assistance (UA) needs to be designed for (especially for high-end users), with some considerations made for age, while the gender and culture of users are not major factors. Help also needs to be contextual and concise, embedded close to the action. That users are saying things like “If I want help on Office, I go to Google ” isn't all that profound at this stage, but it is always worth reiterating how search can be optimized to return better results for users. Interestingly, regardless of user education level, the issue of information quality--hinging on the lynchpin of terminology reflecting that of the user--is critical. Major takeaway for me there. Matthew Ellison’s sessions on embedded help and demos were also impressive. Embedded help that is concise and contextual is definitely a powerful UX enabler, and I’m pleased to say that in Oracle Fusion Applications we have embraced the concept fully. Matthew also mentioned in his session about successful software demos that the principle of modality with demos is a must. Look no further than Oracle User Productivity Kit demos See It!, Try It!, Know It, and Do It! modes, for example. I also found some key takeaways in the presentation by Marie-Louise Flacke on notes and warnings. Here, legal considerations seemed to take precedence over providing any real information to users. I was delighted when Marie-Louise called out the Oracle JDeveloper documentation as an exemplar of how to use notes and instructions instead of trying to scare the bejaysus out of people and not providing them with any real information they’d find useful instead. My own session on designing messages for enterprise applications was well attended. Knowing your user profiles (remember user expertise is the king maker for UA so write for each audience involved), how users really work, the required application business and UI rules, what your application technology supports, and how messages integrate with the enterprise help desk and support policies and you will go much further than relying solely on the guideline of "writing messages in plain language". And, remember the value in warnings and confirmation messages too, and how you can use them smartly. I hope y’all got something from my presentation and from my answers to questions afterwards. Ellis Pratt stole the show with his presentation on applying game theory to software UA, using plenty of colorful, relevant examples (check out the Atlassian and DropBox approaches, for example), and striking just the right balance between theory and practice. Completely agree that the approach to take here is not to make UA itself a game, but to invoke UA as part of a bigger game dynamic (time-to-task completion, personal and communal goals, personal achievement and status, and so on). Sure there are gotchas and limitations to gamification, and we need to do more research. However, we'll hear a lot more about this subject in coming years, particularly in the enterprise space. I hope. I also heard good things about the different sessions about DITA usage (including one by Sonja Fuga that clearly opens the door for major innovation in the community content space using WordPress), the progressive disclosure of information (Cerys Willoughby), an overview of controlled language (or "information quality", as I like to position it) solutions and rationale by Dave Gash, and others. I also spent time chatting with Mike Hamilton of MadCap Software, who showed me a cool demo of their Flare product, and the Lingo translation solution. I liked the idea of their licensing model for workers-on-the-go; that’s smart UX-awareness in itself. Also chatted with Julian Murfitt of Mekon about uptake of DITA in the enterprise space. In all, it's worth attending UA Europe. I was surprised, however, not to see conference topics about mobile UA, community conversation and content, and search in its own right. These are unstoppable forces now, and the latter is pretty central to providing assistance now to all but the most irredentist of hard-copy fetishists or advanced technical or functional users working away on the back end of applications and systems. Only saw one iPad too (says the guy who carries three laptops). Tweeting during the conference was pretty much nonexistent during the event, so no community energy there. Perhaps all this can be addressed next year. I would love to see the next UA Europe event come to Dublin (despite Bloomsday, it's not a bad place place, really) now that hotels are so cheap and all. So, what is my overall impression of the state of user assistance in Europe? Clearly, there are still many people in the industry who feel there is something broken with the traditional forms of user assistance (particularly printed doc) and something needs to be done about it. I would suggest they move on and try and embrace change, instead. Many others see new possibilities, offered by UX and technology, as well as the reality of online user behavior in an increasingly connected world and that is encouraging. Such thought leaders need to be listened to. As Ellis Pratt says in his great book, Trends in Technical Communication - Rethinking Help: “To stay relevant means taking a new perspective on the role (of technical writer), and delivering “products” over and above the traditional manual and online Help file... there are a number of new trends in this field - some complementary, some conflicting. Whatever trends emerge as the norm, it’s likely the status quo will change.” It already has, IMO. I hear similar debates in the professional translation world about the onset of translation crowd sourcing (the Facebook model) and machine translation (trust me, that battle is over). Neither of these initiatives has put anyone out of a job and probably won't, though the nature of the work might change. If anything, such innovations have increased the overall need for professional translators as user expectations rise, new audiences emerge, and organizations need to collate and curate user-generated content, combining it with their own. Perhaps user assistance professionals can learn from other professions and grow accordingly.

  • gVim doesn't recognize the Meta (Alt) Key in an imap after changing the encoding

    - by René Nyffenegger
    In order to edit html files, I have the following three imaps in a file that I source for filetype html: imap <buffer> <M-[> &uuml; imap <buffer> <M-;> &ouml; imap <buffer> <M-'> &auml; This works fine until I change the encoding of the html file with set enc=utf-8. Now, pressing Alt-[ for example gives me a Û. Interestingly, after sourcing the same file again, it expands the imaps correctly. This doesn't really make sense to me. So, why is this and how can I have a more constistent environment regarding imap and utf-8. This is occuring with gVim 7.1 for Windows.

  • Clarity is important, both in question and in answer.

    - by gerrylowry
    clarity is important ... i'm often reminded of the Clouseau movie in which Peter Sellers as Chief Inspector Clouseau asks a hotel clerk "Does your dog bite?" ... the clerk answers "no" ... after Clouseau has been bitten by the dog, he looks at the hotel clerk who says "That's not my dog".  Clarity is important, both in question and in answer. i've been a member of forums.asp.net since 2008 ... like many of my peers at forums.asp.net, i've answered my fair share of questions. FWIW, the purpose of this, my first web log post to http://weblogs.asp.net/gerrylowry is to help new members ask better questions and in turn get better answers. TIMTOWTDI  =.  there is more than one way to do it imho, the best way to ask a question in any forum, or even person to person, is to first formulate your question and then ask yourself to answer your own question. Things to consider when asking (the more complete your question, the more likely you'll get the answer you require): -- have you searched Google and/or your favourite search engine(s) before posting your question to forums.asp.net; examples: site:msdn.microsoft.com entity framework 5.0 c#http://lmgtfy.com/?q=site%3Amsdn.microsoft.com+entity+framework+5.0+c%23 site:forums.asp.net MVC tutorial c#http://lmgtfy.com/?q=site%3Aforums.asp.net+MVC+tutorial+c%23 -- are you asking your question in the correct forum?  look at the forums' descriptions at http://forums.asp.net/; examples: Getting Started If you have a general ASP.NET question on a topic that's not covered by one of the other more specific forums - ask it here. MVC Discussions regarding ASP.NET Model-View-Controller (MVC) C# Questions about using C# for ASP.NET development Note:  if your question pertains more to c# than to MVC, choosing the C# forum is likely to be more appropriate. -- is your post subject clear and concise, yet not too vague? compare these three subjects (all three had something to do with GridView):     (1)    please help     (2)    gridview      (3)    How to show newline in GridView  -- have you clearly explained your scenario? compare:  my leg hurts   with   when i walk too much, my right knee hurts in the knee joint  compare:  my code does not work    with    when i enter a date as 2012-11-8, i get a FormatException -- have you checked your spelling, your grammar, and your English? for better or worse, English is the language of forums.asp.net ... many of the currently 170000++ forums.asp.net are not native speakers of English; that's okay ... however, there are times when choosing the more appropriate words will likely get one a better answer; fortunately, there are web tools to help you formulate your question, for example, http://translate.google.com/.  -- have you provided relevant information about your environment? here are a few examples ... feel free to include other items to your question ... rule of thumb:  if you think a given detail is relevant, it likely is -- what technology are you using?    ASP.NET MVC 4, ASP.NET MVC 3, WebForms, ...  -- what version of Visual Studio are you using?  vs2012 (ultimate, professional, express), vs2010, vs2008 ... -- are you hosting your own website?  are you using a shared hosting service? -- are you experience difficulties in just one browser? more than one browser? -- what browser version(s) are you using?   ie8? ie9? ... -- what is your operating system?     win8, win7, vista, XP, server 2008 R2 ... -- what is your database?   SQL Server 2008 R2, ss2005, MySQL, Oracle, ... -- what is your web server?  iis 7.5, iis 6, .... -- have you provided enough information for someone to be able to answer your question? Here's an actual example from an O.P. that i hope is self-explanatory: I'm trying to make a simple calculator when i write the code in windows application it worked when i tried it in web application it doesn't work and there are no errors what should i do ??!! -- have you included unnecessary information? more than once, i've seen the O.P. (original post, original poster) include many extra lines of code that were not relevant to the actual question; the more unnecessary code that you include, the less likely your volunteer peers will be motivated to donate their time to help you. -- have you asked the question that you want answered? "Does this dog bite?" -- are your expectations reasonable? -- generally, persons who are going to answer your questions are your peers ... they are unpaid volunteers ... -- are you looking for help with your homework, work assignment, or hobby? or, are you expecting someone else to do your work for you?  -- do you expect a complete solution or are you simply looking for guidance and direction? -- you are likely to get more help by first making a reasonable effort to help yourself first Clarity is important, both in question and in answer. if you are answering someone else's question, please remember that clear answers are just as important as clear questions; would you understand your own answer? Things to consider when answering: -- have you tested your code example?  if you have, say so; if you've not tested your code example, also say so -- imho, it's okay to guess as long as you clearly state that you're guessing ... sometimes a wrong guess can still help the O.P. find her/his way to the right answer -- meanness does not contribute to being helpful; sometimes one may become frustrated with the O.P. and/or others participating in a thread, if that happens to you, be kind regardless; speaking from my own experience, at least once i've allowed myself to be frustrated into writing something inappropriate that i've regretted later ... being a meany does not feel good ... being kind and helpful feels fantastic! Tip:  before asking your question, read more than a few existing questions and answers to get a sense of how your peers ask and answer questions. Gerry P.S.:  try to avoid necroposting and piggy backing. necroposting is adding to an old post, especially one that was resolved months ago. piggy backing is adding your own question to someone else's thread.

  • ASP.NET MVC 2: How do I make the Ajax.Form to fire the Client Side Validation with Data Annotation?

    - by Methee
    Here is the code I have so far: <% Html.EnableClientValidation(); %> <% using (Ajax.BeginForm("Address", "Accounts", FormMethod.Post, new AjaxOptions(){}, new { id="dialog-form"} )){ %> <div> <label for="address">Address Name:</label> </div> <div> <%= Html.TextBoxFor(m => m.Name)%> <div> <%= Html.ValidationMessageFor(m => m.Name)%> </div> </div> <input type="submit" value="OK" /> <% } %> When I click submit, It does the validation on the server side, I kinda like it to validate on the Client instead of taking a trip to the server right away.

  • mvc presentation model best-practices

    - by Andrew Florko
    Hello, everybody How do you usually convert business objects to presentation? For example: Business object Person { Id, FirstName, LastName, Patronymic ... } should be presented as "LastName F. P. " in html layout. We use Presentation classes hierarchy to represent data ready for output from Business model. Questions: Will you keep presentation model completely separated from Business Model. For example, can strong-typed views (MVC ASP.NET) aggregate formatted business data as well as raw business objects (that leads toward <%=Html.Encode(PersonHelper.ToShort(Model.Person))% html layout injections) What architecture layer do you choose for conversion (mvc controllers that formats business data from business layer, for instance). Thank you in advance

  • Facebook Connect cross-domain receiver URL (XXXXXXX) must have the application's Connect URL as pref

    - by pallab
    I am trying to create a javascript widget which can be placed on any webpage and uses facebook connect to authenticate the user. What I have done is that,in any html file you put a javascript which has a document.write to show the widget. <script type="text/javascript" src="button.js"></script> On clicking the widget, the facecook login happens if the user is not already logged in to facebook (Single Sign On). There are no problems when I am putting the HTML file and the js file in the same directory as specified in the facebook connect URL. However, when I put the HTML file in some other folder and specify the absolute path to the js folder I get the warning "Facebook Connect cross-domain receiver URL (XXXXXXX) must have the application's Connect URL as prefix" The login however happens? How can this be resolved?

    I've developed a website in html/css and it works perfectly fine. Now I'm working with the coder, integrating this to a .NET framework, changing the website to .apsx instead of html, but during the build of the website, the only error that is marked is the load of Cufon , it simply can't load and the structure and syntax of all the commands are the same I used with the html site that actually works. There are no path problems so far. What do you guys think would be this problem ? Thank you for your kind help.

  • Library to parse ERB files

    - by Douglas Sellers
    I am attempting to parse, not evaluate, rails ERB files in a Hpricot/Nokogiri type manner. The files I am attempting to parse contain HTML fragments intermixed with dynamic content generated using ERB (standard rails view files) I am looking for a library that will not only parse the surrounding content, much the way that Hpricot or Nokogiri will but will also treat the ERB symbols, <%, <%= etc, as though they were html/xml tags. Ideally I would get back a DOM like structure where the <%, <%= etc symbols would be included as their own node types. I know that it is possible to hack something together using regular expressions but I was looking for something a bit more reliable as I am developing a tool that I need to run on a very large view code base where both the html content and the erb content are important. For example, content such as: blah blah blah <divMy Great Text <%= my_dynamic_expression %</div Would return a tree structure like: root - text_node (blah blah blah) - element (div) - text_node (My Great Text ) - erb_node (<%=)

  • CSS Margins Increase with H1 Length

    - by Ethan Turkeltaub
    Consider the following markup: <!DOCTYPE html> <html> <head> <title>Test Page</title> <link href="screen.css" rel="stylesheet" /> </head> <body> <h1>Test</h1> <h3>Description</h3> </body> </html> And the CSS: h3{ margin-top: -25px; } Now, I want the H3 to have a margin-left of however long H1 is, and it is consistently 20px away. So, if I have a H1 block of 200px long, then H3 would have a margin-left of 220px, and so on and so forth. How would I do this?

  • Avoid XmlDocument validating namespaces in C#

    - by Abbey Kingston
    Hello, I'm trying to find a way of indenting a HTML file, I've been using XMLDocument and just using a XmlTextWriter. However I am unable to format it correctly for HTML documents because it checks the doctype and tries to download it. Is there a "dumb" indenting mechanism that doesnt validate or check the document and does a best effort indentation? The files are 4-10Mb in size and they are autogenerated, we have to handle it internal - its fine, the user can wait, I just want to avoid forking to a new process etc. Essentially, right now I use a MemoryStream, XmlTextWriter and XmlDocument, once indented I read it back from the MemoryStream and return it as a string. Failures happen for XHTML documents and some HTML 4 documents because its trying to grab the dtds. I tried setting XmlResolver as null but to no avail :(

  • Can you clear jquery ajax cache?

    - by chobo2
    Hi I am wondering is it possible to clear the cache from a particular ajax method? Say if I have this $.ajax({ url: "test.html", cache: true, success: function(html){ $("#results").append(html); } }); Now 99% of the time a cached result can be used since it should always be same content. However if a user updates this content it of course changes. If it is cached and it would still show the old content. So it would be cool if I could pick out this cache for this method and clear it and all other cached stuff would stay. Can this be done?

  • Authorizing sections of a view in MVC

    - by Duk
    I was wondering if it's possible to authorize parts of a view inside the view. For example, I understand how to authorize the entire controller in this method <HandleError()> _ Public Class HomeController Inherits System.Web.Mvc.Controller Function Index() Return View() End Function <Authorize(Roles:="Administrators")> _ Function AdministratorSecrets() Return View() End Function End Class But what Id like to do is have it so if the admin is logged in, they can see additional links in my navigation. Something along the lines of <ul id="menu"> <li><%= Html.ActionLink("Home", "Index", "Home")%></li> <li><%= Html.ActionLink("About", "About", "Home")%></li> <Authorize(Roles:="Administrators")> _ <li><%= Html.ActionLink("Admin", "Admin", "Home")%></li> </ul> Obviously that won't work, but it gives an idea of what I'm trying to accomplish. Any ideas?

  • Security Level for WebBrowser control

    - by jaywon
    I am trying to migrate an .hta application to a C# executable. Of course, since it's an .hta the code is all HTML and Jscript, with calls to local ActiveX objects. I created a C# executable project and am just using the WebBrowser control to display the HTML content. Simply renamed the .hta to an .html and took out the HTA declarations. Everything works great, except that when I make calls to the ActiveX objects, I get a security popup warning of running an ActiveX control on the page. I understand why this is happening since the WebBrowser control is essentially IE and uses the Internet Options security settings, but is there any way to get the WebBrowser control to bypass security popups, or a way to register the executable or DLLs as being trusted without having to change settings in Internet Options? Even a way to do on a deployment package would work as well.

  • How to escape HAML for Javascript in Sinatra

    - by viatropos
    I would like to return a list/combobox from an ajax request ("Which on of these do you like?" type thing). I would like to write that little snippet in HAML, which converts it to HTML, but when I do, the page goes blank. I'm assuming this is because the HTML isn't escaped. Is there a way to escape HAML so I can do $("#mydiv").html(response);? Here's the method: post "/something" do # process... haml :"partials/_select", :layout => false, :locals => {:collection => choices} end ... the haml template: %select - collection.each do |item| %option{:value => item.to_s}= item.to_s ... and the javascript: success: function(responseText, statusText, xhr, $form) { $(".dialog_content").append(responseText); } I have tried the sinatra_more plugin and the escape_javascript method, but there's problems with the haml buffer in sinatra. Any ideas?

  • jQuery ajax() function is ignoring dataType parameter in Firefox

    - by ccleve
    I'm trying to use jQuery.ajax() to fetch some html, but Firefox is giving me a "junk after document element" error message. As explained here and here the problem seems to be that Firefox is expecting XML from the server, and when it doesn't parse correctly it throws the error. Here's my ajax code: jQuery.ajax({ url: name, dataType: "html", success: function(result) { console.log(result); }, error: function (jqXHR, textStatus, errorThrown) { console.log(errorThrown); } }); The server returns the html with these response headers: Accept-Ranges bytes Content-Length 2957 Last-Modified Tue, 02 Jul 2013 16:16:59 GMT Note that there's no content-type header. I'm sure that adding one would solve the problem, but that's not an option. The real problem is that Firefox appears to be ignoring the dataType: parameter in the ajax call. I've also tried adding contentType: and accepts: parameters, but it doesn't help. What am I missing here? How do I force Firefox to process the response as plain text?

  • jQuery fadeOut, replaceWith, animate almost working

    - by Jesse
    I am trying to accomplish the following: 1. On click, have a div with id="fader" fadeout 2. replaceHtml of fader with new html (this new HTML will appear below the fold of the browser) 3. Animate new HTML to slide up to the specified location Step 1 and 2 are working, step 3 is not and I'm stumped as to why. Here's the javascript: $("#fader").fadeOut(1000, function() { $(this).replaceWith('<div id=\"fader\" style=\"margin-top:-500px;width:500px;height:400px;border:1px solid black;\">new div</div>', function() { $("#fader").animate({marginTop: "500px"}); }); }); Any thoughts on why the div won't animate would be greatly appreciated, thanks in advance!

  • jQuery .Ajax() function selector , store specific data in variable

    - by user279321
    I am new to jQuery and I have the following problem. My project has say 2 pages, 1.JSP and 2.html. Now I want to pick selected data from 2.html and use it on 1.JSP. Now this was achieved very easily using .load but I want the data to be present in a JavaScript variable rather than put it on the page (div tags, etc.), so that I can work upon that data (modify or add to database). I tried using .ajax and was able to write the following code: var value = (function () { var val = nulll; var filename = " 2.html"; $.ajax ({ 'async': false, 'global': false, 'url': filename, 'success' : function(data) { val = data; } }) return val; })() document.write(value) Where do I put the selector format (say div.id5) so that my variable have only relevant data rather than the full file data?

    im trying to implement a Chat feature in my application. i have used 2 JEditorPane. one for holding chat history and the other for sending chat to the previous JEditorPane. the JEditorPane is text/html type. the problem i am having is when i put more than one space between characters it is automatically removed by the parser because it is HTML! how can i make it so, that the spaces are not stripped? example: hello world becomes: hello world. also i am having to parse the html tags so the new messages can be added to the history window. is there a better option than using JEditorPane? if i used JTextPane would it be easier to implement? i would like the chat boxes/panes to be able to handle bold, URL embedding for now. thank you and look forward to your guidance.

  • Displaying most popular posts on my blog - Ruby on Rails

    - by bgadoci
    I have created a simple blog application using Ruby on Rails, both of which I am new to. I am trying to get my most 'voted' posts to display in my /views/posts/index.html.erb view. Here are the basics. I have created a votes table and successfully allow a user to 'vote' for a post on the /views/posts/show.html.erb page. When they vote, it passes '1' to the votes table and I return the vote count via ajax to the same show page. Vote belongs_to :post and Post has_many :votes. I would like to display in /views/posts/index.html.erb the post title and the amount of times it has been voted for, ordered by posts with the highest vote count. Any ideas on how to do this?
