  • UIHint can not resolve template in abstract models

    - by Reza Owliaei
    Assume an abstract model like this: public abstract class MyClass : BaseEntity { [UIHint("File")] public long? DocumentFileId { get; set; } } The problem is Cannot resolve template 'File', while there is File.cshtml in View editor templates. The point is, if I don't define MyClass as an abstract class, error will be solved. My question is, why editor template can not resolve in abstract classes, and how can I handle it?

  • Need to place a floating modeless form over excel main window (quasi-task pane)

    - by code4life
    Hi I need to emulate a task pane by floating a modeless form over the Excel main window. The reason for this requirement is that I need to have taskpane features for my Excel 2003 add-in, but cannot use the document-centric model. Can anyone suggest what would be the best way to do this? The modeless form would need to detect the main window resize event and resize itself accordingly, and also need to always position itself at the bottom of the window (kind of like a docking pane).

  • correct approach to store in database

    - by John
    I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

  • Efficient storage/retrieval method for replayable comet style applications (Google Wave, Etherpad)

    - by Gareth Simpson
    I am considering a web application that would have the same kind of multi user, automatic saving, infinite undo / replay capabilities that you see in Google Wave and Etherpad (albeit on a drastically smaller scale and userbase). Before I go away and reinvent the wheel, is this something that has already been addressed as either a piece of technology or library, or even just a design pattern. I know this isn't necessarily the best Stack Overflow question as there is probably not a "right" answer, but my Google-fu has failed me and I'd just like a reading list! Ordinarily I would be developing under python/django but this is not a firm requirement just a preference :)

  • What Web design tool would make a good CityDesk replacement?

    - by Joshua Fox
    I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site. I have used CityDesk, but that is out-of-date, unsupported, and has certain problems. Of course there are lots of tools out there, but I cannot find anything similar to CityDesk: WYSIWYG as well as HTML coding a templating system not overdesigned like, say, Dreamweaver built for developers who understand HTML/JS/CSS but easier to use than hand-coding of PHP, Ruby, or other templates in a text editor supporting the editing of pages by non-developers preferably free I'd also like it to be CSS-aware; and to have lots of free templates available. Or alternatively, static template-based sites are often developed nowadays on the Web using a CMS like Django; is that the way to go? Edit: Namo, DreamWeaver, NetObjects Fusion, Coffee Cup, Evrsoft First Page, and Microsoft Expression might be candidates. I'll appreciate comments on these based on the criteria above.

  • Python Scraper for Javascript?

    - by Diego
    Hey all, Can anyone direct me to a good Python screen scraping library for javascript code (hopefully one with good documentation/tutorials)? I'd like to see what options are out there, but most of all the easiest to learn with fastest results... wondering if anyone had experience. I've heard some stuff about spidermonkey, but maybe there are better ones out there? Specifically, I use BeautifulSoup and Mechanize to get to here, but need a way to open the javascript popup, submit data, and download/parse the results in the javascript popup. <a href="javascript:openFindItem(12510109)" onclick="s_objectID=&quot;javascript:openFindItem(12510109)_1&quot;;return this.s_oc?this.s_oc(e):true">Find Item</a> I'd like to implement this with Google App engine and Django. Thanks!

  • How do CUDA devices handle immediate operands?

    - by Jack Lloyd
    Compiling CUDA code with immediate (integer) operands, are they held in the instruction stream, or are they placed into memory? Specifically I'm thinking about 24 or 32 bit unsigned integer operands. I haven't been able to find information about this in any of the CUDA documentation I've examined so far. So references to any documents on specific uarch details like this would be perfect, as I don't currently have a good model for how CUDA works at this level.

  • JQuery Autocomplete CSS not working?

    - by gath
    I am trying to implement JQuery Autocomplete pluggi using Django. I've been able to wire the thing together and I can actually see the result back in the HTML template. My problem is that the JQuery Autocomplete CSS doesn't seem to work. The results I get are not well formatted/styled, and they have no background and you cannot even select them. What is it that am missing? I have these three files in my media folder same folder: autocomplete.js dimensions.js autocomplete.css In my html template I have the following function: $(function(){ setAutoComplete("tags", "tagResults", "/taglookup/?query="); }); My textfield looks like this; <input type="text" name="tags" value=""> Where do I put the tagResults in my HTML template document? Every time I try to introduce a DIV with id="tagResults", JQuery throws an error. Any ideas?

    I have a drop down list of Type in my Products model.

I can get normal search methods working where the user enters in their search in a text box but I cannot get it working when they just select from a dropdown. Can anyone help?

  • Is str.replace(..).replace(..) ad nauseam a standard idiom in Python?

    - by meeselet
    For instance, say I wanted a function to escape a string for use in HTML (as in Django's escape filter): def escape(string): """ Returns the given string with ampersands, quotes and angle brackets encoded. """ return string.replace('&', '&amp;').replace('<', '&lt;').replace('>', '&gt;').replace("'", '&#39;').replace('"', '&quot;') This works, but it gets ugly quickly and appears to have poor algorithmic performance (in this example, the string is repeatedly traversed 5 times). What would be better is something like this: def escape(string): """ Returns the given string with ampersands, quotes and angle brackets encoded. """ # Note that ampersands must be escaped first; the rest can be escaped in # any order. return replace_multi(string.replace('&', '&amp;'), {'<': '&lt;', '>': '&gt;', "'": '&#39;', '"': '&quot;'}) Does such a function exist, or is the standard Python idiom to use what I wrote before?

  • Calculating spam probability

    - by Hobhouse
    I am building a website in python/django and want to predict wether a user submission is valid or wether it is spam. Users have an accept rate on their submissions, like this website has. Users can moderate other users' submissions; and these moderations are later metamoderated by an admin. Given this: user A with an submission accept rate of 60% submits something. user B moderates A's post as a valid submission. However, his moderations are often wrong, and his moderations' accept rate is a mere 30%. user C moderates A's post as spam. User C is usually right. His moderations' accept rate is 80%. How can I predict the chance of A's post being spam?

  • How to add new object to an IList mapped as a one-to-many with NHibernate?

    - by Jørn Schou-Rode
    My model contains a class Section which has an ordered list of Statics that are part of this section. Leaving all the other properties out, the implementation of the model looks like this: public class Section { public virtual int Id { get; private set; } public virtual IList<Static> Statics { get; private set; } } public class Static { public virtual int Id { get; private set; } } In the database, the relationship is implemented as a one-to-many, where the table Static has a foreign key pointing to Section and an integer column Position to store its index position in the list it is part of. The mapping is done in Fluent NHibernate like this: public SectionMap() { Id(x => x.Id); HasMany(x => x.Statics).Cascade.All().LazyLoad() .AsList(x => x.WithColumn("Position")); } public StaticMap() { Id(x => x.Id); References(x => x.Section); } Now I am able to load existing Statics, and I am also able to update the details of those. However, I cannot seem to find a way to add new Statics to a Section, and have this change persisted to the database. I have tried several combinations of: mySection.Statics.Add(myStatic) session.Update(mySection) session.Save(myStatic) but the closest I have gotten (using the first two statements), is to an SQL exception reading: "Cannot insert the value NULL into column 'Position'". Clearly an INSERT is attempted here, but NHibernate does not seem to automatically append the index position to the SQL statement. What am I doing wrong? Am I missing something in my mappings? Do I need to expose the Position column as a property and assign a value to it myself? EDIT: Apparently everything works as expected, if I remove the NOT NULL constraint on the Static.Position column in the database. I guess NHibernate makes the insert and immediatly after updates the row with a Position value. While this is an anwers to the question, I am not sure if it is the best one. I would prefer the Position column to be not nullable, so I still hope there is some way to make NHibernate provide a value for that column directly in the INSERT statement. Thus, the question is still open. Any other solutions?

  • friendship database schema

    - by Daniel Hertz
    I'm creating a db schema that involves users that can be friends, and I was wondering what the best way to model the ability for these friends to have friendships. Should it be its own table that simply has two columns that each represent a user? Thanks!
