  • Routing Business Branches: Granular access control in ASP.NET MVC

    - by FreshCode
    How should ASP.NET MVC routes be structured to allow granular role-based access control to business branches? Every business entity is related to a branch, either by itself or via its parent entities. Is there an elegant way to authorize actions based on user-roles for any number of branches? 1. {branch} in route? {branch}/{controller}/{action}/{id} Action: [Authorize(Roles="Technician")] public ActionResult BusinessWidgetAction(BusinessObject obj) { // Authorize will test if User has Technician role in branch context // ... } 2. Retrieve branch from business entity? {controller}/{action}/{id} Action: public ActionResult BusinessWidgetAction(BusinessObject obj) { if (!User.HasAccessTo("WidgetAction", obj.Branch)) throw new HttpException(403, "No soup for you!"); // or redirect // ... } 3. Or is there a better way?

  • Complex queries using Rails query language

    - by Daniel Johnson
    I have a query used for statistical purposes. It breaks down the number of users that have logged-in a given number of times. User has_many installations and installation has a login_count. select total_login as 'logins', count(*) as `users` from (select u.user_id, sum(login_count) as total_login from user u inner join installation i on u.user_id = i.user_id group by u.user_id) g group by total_login; +--------+-------+ | logins | users | +--------+-------+ | 2 | 3 | | 6 | 7 | | 10 | 2 | | 19 | 1 | +--------+-------+ Is there some elegant ActiveRecord style find to obtain this same information? Ideally as a hash collection of logins and users: { 2=>3, 6=>7, ... I know I can use sql directly but wanted to know how this could be solved in rails 3.

  • Initializing "new users" in Rails

    - by mathee
    I'm creating a Ruby on Rails application, and I'm trying to create/login/logout users. This is the schema for Users: create_table "users", :force => true do |t| t.string "first_name" t.string "last_name" t.text "reputation" t.integer "questions_asked" t.integer "answers_given" t.string "request" t.datetime "created_at" t.datetime "updated_at" t.string "email_hash" t.string "username" t.string "hashed_password" t.string "salt" end The user's personal information (username, first/last names, email) is populated through a POST. Other things such as questions_asked, reputation, etc. are set by the application, so should be initialized when we create new users. Right now, I'm just setting each of those manually in the create method for UsersController: def create @user = User.new(params[:user]) @user.reputation = 0 @user.questions_asked = 0 @user.answers_given = 0 @user.request = nil ... end Is there a more elegant/efficient way of doing this?

  • File input javascript event, is there an event fire when someone click okay on the dialog box?

    - by Mickey Cheong
    Hi, When someone click on Browse for the input file below: <input type="file" name="blah" /> A dialog box will appear. The user will then select a file and click 'Ok'. The dialog box will close. Is there an event fire because of that? I tried onfocus and onblur, it didnt work out. The only way is, i start a timer to check the value content when it is onfocus. Not that elegant. Any solution? Cheers, Mickey

  • Processing files with C# in folders whose names contain spaces

    - by Nigel Ainscoe
    There are plenty of C# samples that show how to manipulate files and directories but they inevitably use folder paths that contain no spaces. In the real world I need to be able to process files in folders with names that contain spaces. I have written the code below which shows how I have solved the problem. However it doesn't seem to be very elegant and I wonder if anyone has a better way. class Program { static void Main(string[] args) { var dirPath = @args[0] + "\\"; string[] myFiles = Directory.GetFiles(dirPath, "*txt"); foreach (var oldFile in myFiles) { string newFile = dirPath + "New " + Path.GetFileName(oldFile); File.Move(oldFile, newFile); } Console.ReadKey(); } } Regards, Nigel Ainscoe

  • Verify mail server connection programmatically

    - by Sergii
    I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials. Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server. Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid. I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant. Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated. Thanks in advance.

  • How to code Fizzbuzz in F#

    - by Russell
    I am currently learning F# and have tried (an extremely) simple example of FizzBuzz. This is my initial attempt: for x in 1..100 do if x % 3 = 0 && x % 5 = 0 then printfn "FizzBuzz" elif x % 3 = 0 then printfn "Fizz" elif x % 5 = 0 then printfn "Buzz" else printfn "%d" x What solutions could be more elegant/simple/better (explaining why) using F# to solve this problem? Note: The FizzBuzz problem is going through the numbers 1 to 100 and every multiple of 3 prints Fizz, every multiple of 5 prints Buzz, every multiple of both 3 AND 5 prints FizzBuzz. Otherwise, simple the number is displayed. Thanks :)

  • How to dynamically load & unload a TinyMCE Plugin

    - by Matt Simpson
    Does anyone know if there is a way I can dynamically load and unload a TinyMCE plugin after TinyMCE has already been loaded? Specifically, I'm thinking about asking the user whether or not they wish to load the fullpage plugin using perhaps a radio button or something above TinyMCE: <input type="radio" name="fullpage" value="enabled" /> Enable Fullpage Plugin<br /> <input type="radio" name="fullpage" value="disabled" /> Disable Fullpage Plugin<br /> <textarea name="tinymce" id="tinymce">...</textarea> I suppose I could destroy the original instance and load a new config (one for enabled / one for disabled), but it seems as though there should be a more elegant way of loading and unloading plugins.

  • Using Java server-side with PHP-generated front-end

    - by Storm
    Hi!  Does anyone have a real-world experience in building such a project? I'd like to move away questions about "is it good idea or not", but focus on possible solutions. I see one simple way - HTTP GET/POST + xml/json - and one more elegant - AJAX/DWR. As for the first one - I understand that it is possible, but needs quite a lot coding. As for second way - is it possible to use Java DWR engine with PHP front-end? Is DWR language-independent for client side (as it uses just JavaScript)?  Would it be a problem, that client page was generated by one web server (for example, apache+php) and served on server-side by another (for example, tomcat)? I suspect, that Tomcat will complain about sessions. Can this problem be fixed with allowing cross-domain AJAX? Thank you in advance. Denis.

  • Multiple levels of 'collection.defaultdict' in Python

    - by Morlock
    Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

  • STL map inside map C++

    - by Prasanth Madhavan
    In c++ STL map, i have a definition like map<string, map<int, string> >; and i iterate it using the following code. for( map<string, map<int, string> >::iterator ii=info.begin(); ii!=info.end(); ++ii){ for(map<int, string>::iterator j=ii->second.begin(); j!=ii->second.end();++j){ cout << (*ii).first << " : " << (*j).first << " : "<< (*j).second << endl; } } My doubt is is this the correct way to iterate or is there a better way to do so? The above code works for me. But m looking for a more elegant solution.

  • F# return type coercion

    - by Alex
    Hi, In F# I have a function that returns System.Linq.Expression instances: and System.Object with member this.ToExpression() = match this with | :? System.Int32 -> Expression.Constant(this) :> Expression | :? System.Boolean -> Expression.Constant(this) :> Expression | :? Tml.Runtime.Seq as s -> s.ToExpression() | _ -> failwith "bad expression" If I omit the type coercions on the return values F# will infer the return type of the function to ConstantExpression. My first thought was to explicitly mark the return type as being : #Expression, but that didn't work. Is there a more elegant way of doing this that doesn't involve manually casting return types to the most generic type? Thanks.

  • Drupal 6 / Views2 Grid style: whole cells link to nodes

    - by jackocnr
    I have a Users page, which is simply a nicely styled grid (HTML table) of users. I'm displaying a few fields for each one, and both the name and the profile picture have been set to link to the user node. What is the best way to change it so that the whole cell (HTML td) links to the user node? Would you have to use javascript? I've looked into modifying the theme of the view (over-riding the Style output e.g. views-view-grid--users.tpl.php), but cant see an elegant way to get the URL of the user node. And I think you would have to use javascript anyway to turn a whole block element into a link.

  • Android Activities UI Persistence

    - by aandroid
    I need to have two activities in an Android app that can be switched between each other with UI persistence as follows: Activity A launches Activity B. User triggers some UI changes in Activity B. Activity B returns to Activity A (by a call to onBackPressed() or something similar) Activity A re-launches Activity B. I would like the changes made in step 2 to be visible in step 4. I have tried using the singleInstance activity tag on Activity B to no avail. I would also prefer a more elegant solution than simply writing all object properties to a file or SQLite table. It seems that this behaviour must be easily achievable given that Android does it automatically for calls to onBackPressed() where the parent Activity's UI is saved. Any help is much appreciated.

  • Valid Dates in AppEngine forms (Beginner)

    - by codingJoe
    In AppEngine, I have a form that prompts a user for a date. The problem is that when the clicks enter there is an error: "Enter a Valid Date" How do I make my Form accept (for example) %d-%b-%Y as the date format? Is there a more elegant way to accomplish this? # Model and Forms class Task(db.Model): name=db.StringProperty() due=db.DateProperty() class TaskForm(djangoforms.ModelForm): class Meta: model = Task # my get function has the following. # using "now" for example. Could just as well be next Friday. tmStart = datetime.now() form = TaskForm(initial={'due': tmStart.strftime("%d-%b-%Y")}) template_values = {'form': form }

  • How to convert an ASCII HEX character to it's value (0-15)?

    - by philcolbourn
    I am writing a string parser and the thought occurred to me that there might be some really interesting ways to convert an ASCII hexadecimal character [0-9A-Fa-f] to it's numeric value. What are the quickest, shortest, most elegant or most obscure ways to convert [0-9A-Fa-f] to it's value between 0 and 15? Assume, if you like, that the character is a valid hex character. I have no chance so I'll have a go at the most boring. ( c <= '9' ) ? ( c - '0' ) : ( (c | '\x60') - 'a' + 10 )

  • Access a content control in C# when using Master Pages

    - by Guillaume Gervais
    Good day everyone, I am building a page in ASP.NET, and using Master Pages in the process. I have a Content Place Holder name "cphBody" in my Master Page, which will contain the body of each Page for which that Master Page is the Master Page. In the ASP.NET Web page, I have a Content tag (referencing "cphBody") which also contains some controls (buttons, Infragistics controls, etc.), and I want to access these controls in the CodeBehind file. However, I can't do that directly (this.myControl ...), since they are nested in the Content tag. I found a workaround with the FindControl method. ContentPlaceHolder contentPlaceHolder = (ContentPlaceHolder) Master.FindControl("cphBody"); ControlType myControl = (ControlType) contentPlaceHolder.FindControl("ControlName"); That works just fine. However, I am suspecting that it's not a very good design. Do you guys know a more elegant way to do so? Thank you! Guillaume Gervais.

  • What 'best practices' exist for handing enum heirarchies?

    - by FerretallicA
    I'm curious as to any solutions out there for addressing enum heirarchies. I'm working through some docs on Entity Framework 4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

  • Capturing USB Plug/Unplug events in Firemonkey

    - by radsdau
    [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

  • vectorized approach to binning with numpy/scipy in Python

    - by user248237
    I am binning a 2d array (x by y) in Python into the bins of its x value (given in "bins"), using np.digitize: elements_to_bins = digitize(vals, bins) where "vals" is a 2d array, i.e.: vals = array([[1, v1], [2, v2], ...]). elements_to_bins just says what bin each element falls into. What I then want to do is get a list whose length is the number of bins in "bins", and each element returns the y-dimension of "vals" that falls into that bin. I do it this way right now: points_by_bins = [] for curr_bin in range(min(elements_to_bins), max(elements_to_bins) + 1): curr_indx = where(elements_to_bins == curr_bin)[0] curr_bin_vals = vals[:, curr_indx] points_by_bins.append(curr_bin_vals) is there a more elegant/simpler way to do this? All I need is a list of of lists of the y-values that fall into each bin. thanks.

  • what pattern to use for multi-argument method?

    - by Omid S
    I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

  • Avoid implicit conversion from date to timestamp for selects with Oracle using Hibernate

    - by sapporo
    I'm using Hibernate 3.2.7.GA criteria queries to select rows from an Oracle Enterprise Edition 10.2.0.4.0 database, filtering by a timestamp field. The field in question is of type java.util.Date in Java, and DATE in Oracle. It turns out that the field gets mapped to java.sql.Timestamp, and Oracle converts all rows to TIMESTAMP before comparing to the passed in value, bypassing the index and thereby ruining performance. One solution would be to use Hibernate's sqlRestriction() along with Oracle's TO_DATE function. That would fix performance, but requires rewriting the application code (lots of queries). So is there a more elegant solution? Since Hibernate already does type mapping, could it be configured to do the right thing? Update: The problem occurs in a variety of configurations, but here's one specific example: Oracle Enterprise Edition 10.2.0.4.0 Oracle JDBC Driver 11.1.0.7.0 Hibernate 3.2.7.GA Hibernate's Oracle10gDialect Java 1.6.0_16

  • How to embed a Python interpreter in a PyQT widget

    - by Mathias
    I want to be able to bring up an interactive python terminal from my python application. Some, but not all, variables in my program needs to be exposed to the interpreter. Currently I use a sub-classed and modified QPlainTextEdit and route all "commands" there to eval or exec, and keep track of a separate namespace in a dict. However there got to be a more elegant and robust way! How? Here is an example doing just what I want, but it is with IPython and pyGTK... http://ipython.scipy.org/moin/Cookbook/EmbeddingInGTK

  • Python: Remove items from a list while iterating in Python

    - by xApple
    My problem is simple: I have a long list of elements that I want to iterate through and check every element against a condition. Depending on the outcome of the condition I would like to delete the current element of the list, and continue iterating over it as usual. I have read a few other threads on this matter. Two solutions seam to be proposed. Either make a dictionary out of the list (which implies making a copy of all the data that is already filling all the RAM in my case). Either walk the list in reverse (which breaks the concept of the alogrithm I want to implement). Is there any better or more elegant way than this to do it ? def walk_list(list_of_g): g_index = 0 while g_index < len(list_of_g): g_current = list_of_g[g_index] if subtle_condition(g_current): list_of_g.pop(g_index) else: g_index = g_index + 1
