• What design considerations should one take to receive text and multiple attachments via web?

  - by ramesh.nagul

  I am developing a web application to accept a bunch of text and attachments (1 or more) via email, web and other methods. I am planning to build a single interface, mostly a web service to accept this content. What design considerations should I make? I am building the app using ASP.NET MVC 2. Should the attachments be saved to disk or in the database? Should the unified single interface be a web service? Pros and cons to using web services to upload files

• Django-allauth redirected to connections

  - by camara90100

  I'm using django-allauth to signup users with Facebook, and I'm setting the ACCOUNT_EMAIL_REQUIRED to True so when a user doesn't have email saved on his account I get redirected to the allauth/templates/socialaccount/Signup.html and when I use a test user to enter a valid email, I get redirect to "connections.html" which then asks me to choose one of the social accounts and remove it. and the form action method is set to 'connections url' so it becomes an infinite loop. anyone knows what's wrong? here's my settings SOCIALACCOUNT_PROVIDERS = \ { 'facebook': { 'SCOPE': ['email', 'publish_stream'], # 'AUTH_PARAMS': { 'auth_type': 'reauthenticate' }, 'METHOD': 'js_sdk' , 'LOCALE_FUNC': lambda request: 'en_US'}} ACCOUNT_EMAIL_REQUIRED =True ACCOUNT_ADAPTER = 'profiles.adapter.MyAccountAdapter' SOCIALACCOUNT_ADAPTER ='profiles.adapter.MySocialAccountAdapter'

• Rails - Override primary key on has_one

  - by Ben Hall

  I have the following associations, basically I want to link via userid and not the id of the object. class Tweet < ActiveRecord::Base has_one :user_profile, :primary_key = 'userid', :foreign_key = 'twitter_userid' class UserProfile < ActiveRecord::Base belongs_to :tweet, :foreign_key = 'userid' However the following spec fails as twitter_userid is reset to the id of the object it "should have the user's twitter id set on their user profile" do t = Tweet.new(:twitter_id = 1, :status = 'Tester', :userid = 'personA', :user_profile = UserProfile.new(:twitter_userid = 'personA', :avatar = 'abc')) t.save! t.user_profile.twitter_userid.should == 'personA' end should have the user's twitter id set on their user profile expected: "personA", got: 216 (using ==) However, the following does pass: it "should return the correct avatar after being saved" do t = Tweet.new(:twitter_id = 1, :status = 'Tester', :userid = 'personA', :user_profile = UserProfile.new(:twitter_userid = 'personA', :avatar = 'abc')) t.save! t.user_profile.avatar.should == 'abc' end How can I force it to use userid and not id? Thanks Ben

• CakePHP: Why does adding 'Security' component break my app?

  - by Steve

  I have a strange problem -- of my own making -- that's cropped up, and is driving me crazy. At some point, I inadvertently destroyed a file in the app/tmp directory...I'm not sure which file. But now my app breaks when I include the "Security" component, and works just fine when it's not included. I'm thinking it might be related to the Security.salt value somehow, or possibly to the saved session info, but I don't really have a deep enough knowledge of CakePHP to figure it out. Can anyone offer any insight here?

• Interface Builder "Simulate Interface" not working

  - by bpapa

  I am using Interface Builder to play around with some ideas. I never noticed that there is a "Simulate Interface" feature which apparently will render the nib in the iPhone simulator. So, I created a view, put one component in there (a Segmented Control), saved it, selected "Simulate Interface", the simulator launched but... nothing rendered in the simulator. Just a black screen. I thought maybe my nib wasn't complete enough, so I've tried it with all of my old nibs and I'm having the same problem with all of them. None of them render in the simulator at all. Is there some trick that I'm missing?

• IE 8 Caching Problem

  - by Jeff Catania

  One of my javascript sources had an extra comma that was throwing an error in IE8. So I opened up my editor, deleted the comma, and saved. I reloaded IE8, but it was still pulling the old js file. I deleted everything in "Delete Browsing History...", and restarted the browser. It is still pulling the old file. I even set up a log on my server to show whenever the js file was requested. When reloading with IE, the js file is never requested. I tried doing the same process in Chrome and FF, and it pulled the new file and logged properly on the server. Is there some other cache that I am failing to clear in IE that would cause this problem?

• Django save, column specified twice

  - by realshadow

  Hey, I would like to save a modified model, but I get Programming error - that a field is specified twice. class ProductInfo(models.Model): product_info_id = models.AutoField(primary_key=True) language_id = models.IntegerField() product_id = models.IntegerField() description = models.TextField(blank=True) status = models.IntegerField() model = models.CharField(max_length=255, blank=True) label = models.ForeignKey(Category_info, verbose_name = 'Category_info', db_column = 'language_id', to_field = 'node_id', null = True) I get this error because the foreign key uses as db_column language_id. If I will delete it, my object will be saved properly. I dont quite understand whats going on and since I have defined almost all of my models this way, I fear its totally wrong or maybe I just missunderstood it... Any ideas? Regards

• How do I maintain formatting of comments when I save them to the database in an asp.net mvc applicat

  - by baijajusav

  The title was probably not very clear. Consider this scnerio: you have a blog site or really just any site where a user can respond via a comment. You want to maintain the formatting for the comments. So paragraph's should be separated, first sentence indented, bolding of keywords allowed, etc. How would one go about doing this? This is something just about every kind of blogging site handles, including this site. My initial guess is that comments are saved to that database either in an xml format or as the raw html. Those are really my only guesses. I suppose magic strings could be used to denote the starting and ending of various formatting as well, but magic strings are generally frowned upon. I'm doing this in an asp.net mvc application. I'm using version 1 of mvc, but I would be willing to move to 2 if that makes for an easy solution here.

• Complex Django filter question

  - by HWM-Rocker

  Lets say I have this class (simplified): class Tag (...): children = models.ManyToManyField(null=True, symmetrical=False) Now I already implemented the functions get_parents, get_all_ancestors. Is there a nice pythonic way to just the top level tags? If I had designed my Tags differently (to point to the parents instead) I would just make get_all_parents().filter(children=null). My first thought is to create a new function that will go recursively through all parents and save those that has none. But is there a possibility with filters or Query-objects to do the same (with fewer lines of code)? Thanks for your help. [edit] When it is finished, it should be a hierarchical tagging system. Each tag can have children, parents, but only the children are saved. I want to get all the top level tags, that point through many children / childrens children to my tag.

• Saving Types generated via Reflection.Emit as code file (.cs) instead of saving it in .dll files

  - by Manish Sinha

  Before start let me tell my experience: I am experienced with C#.NET, web services, XML part and few more. Reflection is something new to me, though I have read extensively on it and tried out some experimental code, but haven't made anything great using reflection I checked out many examples of how we can create Type at runtime and then which can be saved in an assembly (.dll) files. Of all the examples I have seen is about saving the created types in the .dll files instead of code file. Isn't there any way to create the code file out of reflection? I need to create code file since I want to distribute code instead of compiled assemblies. What I want to do is something like xsd.exe does, either spit out a .dll or the code file(in any language). Isn't there any way to create a code file, since most of the place I can find is AssemblyBuilder ab = System.AppDomain.CurrentDomain.DefineDynamicAssembly(an, AssemblyBuilderAccess.Save); and then lastly ab.Save("QuoteOfTheDay.dll");

• PHP: Replace umlauts with closest 7-bit ASCII equivalent in an UTF-8 string

  - by BlaM

  What I want to do is to remove all accents and umlauts from a string, turning "lärm" into "larm" or "andré" into "andre". What I tried to do was to utf8_decode the string and then use strtr on it, but since my source file is saved as UTF-8 file, I can't enter the ISO-8859-15 characters for all umlauts - the editor inserts the UTF-8 characters. Obviously a solution for this would be to have an include that's an ISO-8859-15 file, but there must be a better way than to have another required include? echo strtr(utf8_decode($input), 'ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ', 'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy'); UPDATE: Maybe I was a bit inaccurate with what I try to do: I do not actually want to remove the umlauts, but to replace them with their closest "one character ASCII" aequivalent.

• ListView from cursor with checkbox

  - by ekawas

  Hi, I have a Listview that looks like the following: checkbox:textview {0 .. n} I have a OnCheckChangedListener that listens for checkbox changes (checkbox has focusable set to false as recommended by http://www.mousetech.com/blog/?p=74). The behaviour that I am looking for is that users can click the checkbox to set its state, and they can click on the listview item to get a description. Currently, checkbox state is saved properly and if you click on an item, then it shows a description. However, if you first change a state and then click to get the description, the checkbox reverts to a prior state. In fact all checkboxes revert back to a prior state. Anyone know how i can get this working? Thanks.

• Update panel in Tab Container

  - by Sam_Cogan

  I have a tab container with 5 tabs, each tab contains an update panel. When the user initially opens the form, they can only see the first Tab, the others are set to visible=false. Once they have completed the first form, the hit save which sends a partial postback to save the data to the DB. Once that is saved, I then want to set all the other tabs to visible, however this does not work at the moment, I am assuming because the tab container is not contained in an update panel. How can I get this to work, do I need to put the tab container in it's own update panel, which will obviously then contain all the other update panels, or should I not use an update panel in the first tab and do a full page postback?

• Voting UI for showing like/dislike community comments side-by-side

  - by Justin Grant

  We want to add a comments/reviews feature to our website's plugin gallery, so users can vote up/down a particular plugin and leave an optional short comment about what they liked or didn't like about it. I'm looking for inspiration, ideally a good implementation elsewhere on the web which isn't annoying to end users, isn't impossibly complex to develop, and which enables users to see both good and bad comments side-by-side, like this: Like: 57 votes Dislike: 8 votes --------------------------------- -------------------------------- "great plugin, saved me hours..." "hard to install" "works well on MacOS and Ubuntu" "Broken on Windows Vista with UAC enabled" "integrates well with version 3.2" More... More... Anyone know a site which does something like this?

• Cinema4D XML scene not rendering texture

  - by George Profenza

  I was playing with the Cinema 4D command line options and ran into a problem that might not be specific to the command line options. I saved a basic scene(a textured cube) in two formats: the original .c4d(binary) format and .xml(Cinema 4D XML via File Export). the .c4d file renders with the texture applied, while the .xml file renders without the texture applied. I had a look at the xml file, and there is a node that holds a reference to the image used as texture, and there is another node which seems to store the pixels in xml. When I opened the .xml document in Cinema 4D, the document did store the material with the texture, but it was not applied to the object. Am I missing something when I export to XML ? How can I export a Cinema 4D XML that can render with the texture applied ?

• How to debug and detect hang issue

  - by igor

  I am testing my application (Windows 7, WinForms, Infragistics controls, C#, .Net 3.5). I have two monitors and my application saves and restores forms' position on the first or second monitors. So I physically switched off second monitor and disabled it at Screen Resolution on the windows display settings form. I need to know it is possible for my application to restore windows positions (for those windows that were saved on the second monitor) to the first one. I switched off second monitor and press Detect to apply hardware changes. Then Windows switched OFF the first monitor for a few seconds to apply new settings. When the first monitor screen came back, my application became unresponsive. My application was launched in debug mode, so I tried to navigate via stack and threads (Visual Studio 2008), paused application, started and did not find any thing that help me to understand why my application is not responsive. Could somebody help my how to detect the source of issue.

• Real-time aggregation of files from multiple machines to one

  - by dmitry-kay

  I need a tool which gets a list of machine names and file wildcards. Then it connects to all these machines (SSH) and begins to monitor changes (appendings to the end) in each file matched by wildcards. New lines in each such file are saved to the local machine to the file with the same name. (This is a task of real-time log files collecting.) I could use ssh + tail -f, of course, but it is not very robust: if a monitoring process dies and then restarts, some data from remote files may be lost (because tail -f does not save the position at which it is finished before). I may write this tool manually, but before - I'd like to know if such tool already exists or not.

• Magento: How do I retrieve values from fields submitted with the payment method?

  - by Joseph

  Ok. This is getting a little frustrating. I am trying to create a custom payment module for Magento. The purpose is to use Authorize.net's CIM so that we don't have to worry so much about PCI compliance. The issue I am having is that the users need to be able to access their previous credit cards and use those for purchasing. I have the previous cards being stored in the database. They are also being displayed in the form in the checkout process. My issue comes when I click continue after selecting the payment method. How do I get the values I submitted in the form? Specifically, the value of the radio button the saved code is attached to? I am not sure what if any code is needed for me to post, so let me know if you need anything in particular. Thanks.

• Getting data back from database after an ajax post submit

  - by sslepian

  I've got a web page where the user can add a new item to a category and that item is saved to the database. However, the ID of the item is an identity value for the database table, so I don't know what the ID will be, and I need this ID so that the user can edit the item later. I'm using ajax to make a POST submit: $.ajax({ url: 'TumourGroup/CreateSub', type: "POST", data: {'pos': index, 'text': text } }); This is linked to an MVC model with three fields, ID, pos, and text. Is there a way for me to get the ID that's generated on POST submit by having CreateSub(int index, string text) return something?

• Two models, one STI and a Validation

  - by keruilin

  Let's say I have two tables -- Products and Orders. For the sake of simplicity assume that only one product can be purchased at a time so there is no join table like order_items. So the relationship is that Product has many orders, and Order belongs to product. Therefore, product_id is a fk in the Order table. The product table is STI -- with the subclasses being A, B, C. When the user orders subclass Product C, two special validations must be checked on the Order model fields order_details and order_status. These two fields can be nil for all other Product subclasses (ie A and B). In other words, no validation needs to run for these two fields when a user purchases A and B. My question is: How do I write validations (perhaps custom?) in the Order model so that the Order model knows to only run the validations for the two fields -- order_details and order_status -- when Product subclass C is being saved to the orders table?

• Respecting EXIF orientation when displaying iPhone photos on the web

  - by GingerBreadMane

  I am developing an iPhone camera app that uploads an image to Amazon S3 and that image is displayed on a website. When the iPhone takes a picture, it always saves the photo in an upright orientation, while the orientation used to correctly view the photo is saved in the image's EXIF data. So if I take a photo with the iPhone and open it in FireFox without processing the EXIF data, the image could be sideways or upside down. My problem is that I don't know how to display the photo in it's correct orientation on the website. My current solution is to rotate the photo in the iPhone app, but I'd rather not do that. Is there anyway to respect the EXIF data when displaying on the web without pre-processing the image?

• C#: How to Make it Harder for Hacker/Cracker to Get Around or Bypass the Licensing Check?

  - by Peter Lee

  Hi all, Suppose that the user has saved the License file under the Application.StartupPath, where all users can read. And then, every time when the app starts, it will check if it can find and verify the license file. If the app can find and verify, we let the user to continue with full functinalities. If not, we prompt a MessageBox showing "Unlicencsed, continue to use with trial version, functionalities limited." My question is, if I'm a hacker/cracker, I would try to get around or bypass the licensing check instead of cracking the license file, because, if we use RSA signature, it's very difficult to crack a license file. So where should we put the license check? thanks. Merry Christmas and Happy New Year! Peter P.S.: and also, is it safe if I put a global variable IsLicensed (true / false) to limit the functionalities? Is it easy for a hacker to change IsLicensed = true?
