    - by Cédric
    Hi everyone, I am currently working on a project and i would like my users to be able to backup/restore theirs accounts. I am looking for a rails plugin/gem that would easily do that, ie : current_user.backup() = backup_file current_user.restore(backup_file) = database import/replace I don't know if my question is very clear, but i would like to backup every user's related object (posts, comments, etc) and to be able to restore them from a backup file. Thanks per advance, Cédric.

  • DocumentFragment not appending in IE

    - by bmwbzz
    I have a select list which, when changed, pulls data via ajax and dynamically creates select lists. Then based on the data used to create the select lists (a type), I pull more data via ajax if i don't have it already and create the options for the select list and store them in a fragment. Then I append that fragment to the select list. This is zippy in FF3 and Chrome but either doesn't append the options at all or takes a long time (minutes) to append the options in IE7. Note: I am also using jQuery. code from the success callback which creates the select lists: blockDiv.empty(); var contentItemTypes = new Array(); selectLists = new Array(); for (var post in msg) { if (post != undefined) { var div = fragment.cloneNode(true); //deep copy var nameDiv = $(div.firstChild); nameDiv.text(msg[post].Name); blockDiv[0].appendChild(div); var allSelectLists = blockDiv.find('.editor-field select'); var selectList = $(allSelectLists[allSelectLists.length - 1]); var blockId = msg[post].ID; var elId = 'PageContentItem.' + blockId; selectList.attr('id', elId); selectList.attr('name', elId); var contentItemTypeId = msg[post].ContentItemTypeId; selectList.attr('cit', contentItemTypeId); if (contentItems[contentItemTypeId] != null || contentItems[contentItemTypeId] != undefined) { contentItems[contentItemTypeId] = null; } selectLists[post] = selectList; } } var firstContentTypeId = selectLists[0].attr('cit'); getContentItems(firstContentTypeId, setContentItemsForList, 0); code to get the items for the options in the select lists. function getContentItems(contentTypeId, callback, callbackParam) { if (contentItems[contentTypeId] != null || contentItems[contentTypeId] != undefined) { callback(contentTypeId, callbackParam); return; } contentItems[contentTypeId] = document.createDocumentFragment(); Q.ajax({ type: "POST", url: "/CMS/ContentItem/ListByContentType/" + contentTypeId, data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", error: function(xhr, msg, e) { var err = eval("(" + xhr.responseText + ")"); alert(err.ExceptionType + " ***** " + err.Message + " ***** " + err.StackTrace); }, success: function(msg) { var li; for (var post in msg) { if (post != undefined) { li = $('<option value="' + msg[post].ID + '">' + msg[post].Description + '</option>'); contentItems[contentTypeId].appendChild(li[0]); } } callback(contentTypeId, callbackParam); } }); } function setContentItemsForList(contentTypeId, selectIndex) { if (selectIndex < selectLists.length) { var items = contentItems[contentTypeId].cloneNode(true); selectLists[selectIndex].append($(items.childNodes)); selectIndex++; if (selectIndex < selectLists.length) { var nextContentTypeId = selectLists[selectIndex].attr('cit'); getContentItems(nextContentTypeId, setContentItemsForList, selectIndex); } } }

  • How do I write a single-file Django application?

    - by obvio171
    I want to write a very small Django application in a single file, requiring all the appropriate modules and stuff, and then be able to run that as a normal Python script, like this: $ python myapp.py You can assume I won't render HTML, so I don't need templates (I'll return JSON or some other auto-generated string).

  • Other HTML serialisations?

    - by Delan Azabani
    After keeping in mind that HTML has both an SGML and XML serialisations, which are just encodings for a parser to "explode" into a DOM, I'm wondering whether there are other serialisations for HTML. A JSON serialisation? If so, are there any parsers for these alternative serialisations?

  • Loading css rules dynamically in Webkit (Safari/Chrome)

    - by Patrick
    Hi all, I currently have issues in Webkit(Safari and Chrome) were I try to load dynamically (innerHTML) some html into a div, the html contains css rules (...), after the html gets rendered the style definitions are not loaded (so visually I can tell the styles are not there and also if I search with javascript for them no styles are found). I have tried using a jquery plugin tocssRule(), it works but it is just too slow. Is there another way of getting webkit to load the styles dynamically? Thanks. Patrick

  • Updating and Editing Google Contacts - Ruby Gem

    - by Kyle
    I'm attempting to interact with the Google contacts API through Rails via and oauth-plugin. I need to retrieve and update Google contacts. I know that the portablecontacts gem will retrieve contacts, but does not allow for adding or updating. I was wondering if anyone knew of a gem that will handle this type of interaction. If not what would be the best method to implement a gem that would make it easier to handle the responses.

  • Porting a Grails application to GAE

    - by xain
    Hi, I currently have a Grails application I'm evaluating to port to Google App Engine and I'd like to know experiences regarding: Acegi security: the application relies on this library to enforce the security. Use of JPA or JDO instead of the hibernate plugin (I'll have to migrate the Domain classes); which one is better ? I have a growing number of pre-generated pdf files I keep uploading; is there any foreseeable problem with this? Thanks in advance.

  • Javascript fine grain performance tweaking

    - by thermal7
    I have been writing my first jQuery plugin and struggling to find a means to time how long different pieces of code take to run. I can use firebug and console.time/profile. However, it seems that because my code executes so fast I get no results with profile and with time it spits out 0ms. (http://stackoverflow.com/questions/2690697/firebug-profiling-issue-no-activity-to-profile/2690846#2690846) Is there a way to get the time at a greater level of detail that milliseconds in javascript?

  • Am I just not understanding TDD unit testing (Asp.Net MVC project)?

    - by KallDrexx
    I am trying to figure out how to correctly and efficiently unit test my Asp.net MVC project. When I started on this project I bought the Pro ASP.Net MVC, and with that book I learned about TDD and unit testing. After seeing the examples, and the fact that I work as a software engineer in QA in my current company, I was amazed at how awesome TDD seemed to be. So I started working on my project and went gun-ho writing unit tests for my database layer, business layer, and controllers. Everything got a unit test prior to implementation. At first I thought it was awesome, but then things started to go downhill. Here are the issues I started encountering: I ended up writing application code in order to make it possible for unit tests to be performed. I don't mean this in a good way as in my code was broken and I had to fix it so the unit test pass. I mean that abstracting out the database to a mock database is impossible due to the use of linq for data retrieval (using the generic repository pattern). The reason is that with linq-sql or linq-entities you can do joins just by doing: var objs = select p from _container.Projects select p.Objects; However, if you mock the database layer out, in order to have that linq pass the unit test you must change the linq to be var objs = select p from _container.Projects join o in _container.Objects on o.ProjectId equals p.Id select o; Not only does this mean you are changing your application logic just so you can unit test it, but you are making your code less efficient for the sole purpose of testability, and getting rid of a lot of advantages using an ORM has in the first place. Furthermore, since a lot of the IDs for my models are database generated, I proved to have to write additional code to handle the non-database tests since IDs were never generated and I had to still handle those cases for the unit tests to pass, yet they would never occur in real scenarios. Thus I ended up throwing out my database unit testing. Writing unit tests for controllers was easy as long as I was returning views. However, the major part of my application (and the one that would benefit most from unit testing) is a complicated ajax web application. For various reasons I decided to change the app from returning views to returning JSON with the data I needed. After this occurred my unit tests became extremely painful to write, as I have not found any good way to write unit tests for non-trivial json. After pounding my head and wasting a ton of time trying to find a good way to unit test the JSON, I gave up and deleted all of my controller unit tests (all controller actions are focused on this part of the app so far). So finally I was left with testing the Service layer (BLL). Right now I am using EF4, however I had this issue with linq-sql as well. I chose to do the EF4 model-first approach because to me, it makes sense to do it that way (define my business objects and let the framework figure out how to translate it into the sql backend). This was fine at the beginning but now it is becoming cumbersome due to relationships. For example say I have Project, User, and Object entities. One Object must be associated to a project, and a project must be associated to a user. This is not only a database specific rule, these are my business rules as well. However, say I want to do a unit test that I am able to save an object (for a simple example). I now have to do the following code just to make sure the save worked: User usr = new User { Name = "Me" }; _userService.SaveUser(usr); Project prj = new Project { Name = "Test Project", Owner = usr }; _projectService.SaveProject(prj); Object obj = new Object { Name = "Test Object" }; _objectService.SaveObject(obj); // Perform verifications There are many issues with having to do all this just to perform one unit test. There are several issues with this. For starters, if I add a new dependency, such as all projects must belong to a category, I must go into EVERY single unit test that references a project, add code to save the category then add code to add the category to the project. This can be a HUGE effort down the road for a very simple business logic change, and yet almost none of the unit tests I will be modifying for this requirement are actually meant to test that feature/requirement. If I then add verifications to my SaveProject method, so that projects cannot be saved unless they have a name with at least 5 characters, I then have to go through every Object and Project unit test to make sure that the new requirement doesn't make any unrelated unit tests fail. If there is an issue in the UserService.SaveUser() method it will cause all project, and object unit tests to fail and it the cause won't be immediately noticeable without having to dig through the exceptions. Thus I have removed all service layer unit tests from my project. I could go on and on, but so far I have not seen any way for unit testing to actually help me and not get in my way. I can see specific cases where I can, and probably will, implement unit tests, such as making sure my data verification methods work correctly, but those cases are few and far between. Some of my issues can probably be mitigated but not without adding extra layers to my application, and thus making more points of failure just so I can unit test. Thus I have no unit tests left in my code. Luckily I heavily use source control so I can get them back if I need but I just don't see the point. Everywhere on the internet I see people talking about how great TDD unit tests are, and I'm not just talking about the fanatical people. The few people who dismiss TDD/Unit tests give bad arguments claiming they are more efficient debugging by hand through the IDE, or that their coding skills are amazing that they don't need it. I recognize that both of those arguments are utter bullocks, especially for a project that needs to be maintainable by multiple developers, but any valid rebuttals to TDD seem to be few and far between. So the point of this post is to ask, am I just not understanding how to use TDD and automatic unit tests?
