  • Where to intercept resolution of controller/view in ASP.Net MVC for customizations?

    - by Jason Jackson
    I am trying to figure out where the appropriate place is to intercept the resolution of what view + controller is being called in ASP.Net MVC 2. I have a situation where I have a controller and a corresponding set of views. I also have the possibility of a customized version of both the controller and N of the views sitting in the project (or we may use something like Portable Views from the MvcContrib project). If the customized version of the controller or view(s) exists at run time, and the user satisfies certain criteria, I need to call the customized controller and use the appropriate customized view. At design/compile time we don't know what customizations may be in place. My first run at this was by using a custom controller factory that returns a custom controller if it exists. However, this controller is "wired up" to the standard view, and I cannot figure out how to return the customized view if it also exists. To complicate matters, there may be no customized controller but customized views, and visa-versa.

  • Given a few strings, how many strings can be lexicographically least by modifying the alphabet?

    - by Jackson W
    Number of strings can be huge as in 30000. Given N strings, output which ones can be lexicographically least after modifying the english alphabet. e.g. acdbe...... for example if the strings were: omm moo mom ommnom "mom" is already lexicographically least with the original english alphabet. we can make the word "omm" least by switching "m" and "o" in the alphabet ("abcdefghijklonmpqrstuvwxyz"). the other ones you cant make lexicographically last, no matter what you do. any fast way to do this? I have no ways to approach this except try every single possible alphabet

  • loading files through one file to hide locations

    - by Phil Jackson
    Hello all. Im currently doing a project in which my client does not want to location ( ie folder names and locations ) to be displayed. so I have done something like this: <link href="./?0000=css&0001=0001&0002=css" rel="stylesheet" type="text/css" /> <link href="./?0000=css&0001=0002&0002=css" rel="stylesheet" type="text/css" /> <script src="./?0000=js&0001=0000&0002=script" type="text/javascript"></script> </head> <body> <div id="wrapper"> <div id="header"> <div id="left_header"> <img src="./?0000=jpg&0001=0001&0002=pic" width="277" height="167" alt="" /> </div> <div id="right_header"> <div id="top-banner"></div> <ul id="navigation"> <li><a href="#" title="#" id="nav-home">Home</a></li> <li><a href="#" title="#">Signup</a></li> all works but my question being is or will this cause any complications i.e. speed of the site as all requests are being made to one single file and then loading in the appropriate data. Regards, Phil

  • Why do Java and C# not have implicit conversions to boolean?

    - by Shaun
    Since I started Java it's been very aggravating for me that it doesn't support implicit conversions from numeric types to booleans, so you can't do things like: if (flags & 0x80) { ... } instead you have to go through this lunacy: if ((flags & 0x80) != 0) { ... } It's the same with null and objects. Every other C-like language I know including JavaScript allows it, so I thought Java was just moronic, but I've just discovered that C# is the same (at least for numbers, don't know about null/objects): http://msdn.microsoft.com/en-us/library/c8f5xwh7(VS.71).aspx Microsoft changed it on purpose from C++, so why? Clearly I'm missing something. Why change (what I thought was) the most natural thing in the world to make it longer to type? What on Earth is wrong with it?

  • How do I keep subdomain.domain.com links from mapping to subdomain.domain.com/subdomain?

    - by Alan Jackson
    I have a virtual directory created and a sub domain that points to that virtual directory. My links always route to subdomain.domain.com/subdomain/controller/action when they can leave off the subdomain link. Is there an easy way to stop that? Also, it's the same problem when I mapped anotherdomain.com to my virtual directory. It ends up linking to anotherdomain.com/virtualdir/controller/action. It just looks unprofessional to me to have all my links be myapp.com/myapp/action/controller.

    Hi, I am looking for ideas for how I can stop external scripts connecting with my site. I'm looking for the same kind of idea behind Google.

Any ideas or links to existing methods or scripts is much appreciated. Regards Phil

  • jQuery, wont change value but will change any othere attribute...

  • Declared Properties and assigning values with self

    - by Shaun Budhram
    I understand how declared properties work - I just need a clarification on when Objective C is using the accessor method vs. when it is not. Say I have a property declared using retain: @property (nonatomic, retain) NSDate *date; ... and later... @synthesize date If I say: date = x Is that calling the accessor method? Or is it just setting the variable? self.date = x This seems to call the accessor method (I think but I'm not sure, since it seems like the retain count is increasing). Can anyone clarify this issue? I'm curious because i have some variables that seem to become invalid before I need them (and I have to specifically call retain), and I suspect this is why.

  • If I use a facade class with generic methods to access the JPA API, how should I provide additional processing for specific types?

    - by Shaun
    Let's say I'm making a fairly simple web application using JAVA EE specs (I've heard this is possible). In this app, I only have about 10 domain/data objects, and these are represented by JPA Entities. Architecturally, I would consider the JPA API to perform the role of a DAO. Of course, I don't want to use the EntityManager directly in my UI (JSF) and I need to manage transactions, so I delegate these tasks to the so-called service layer. More specifically, I would like to be able to handle these tasks in a single DataService class (often also called CrudService) with generic methods. See this article by Adam Bien for an example interface: http://www.adam-bien.com/roller/abien/entry/generic_crud_service_aka_dao My project differs from that article in that I can't use EJBs, so my service classes are essentially just named beans and I handle transactions manually. Regardless, what I want is a single interface for simple CRUD operations on my data objects because having a different class for each data type would lead to a lot of duplicate and/or unnecessary code. Ideally, my views would be able to use a method such as public <T> List<T> findAll(Class<T> type) { ... } to retrieve data. Using JSF, it might look something like this: <h:dataTable value="#{dataService.findAll(data.class)}" var="d"> ... </h:dataTable> Similarly, after validating forms, my controller could submit the data with a method such as: public <T> void add(T entity) { ... } Granted, you'd probably actually want to return something useful to the caller. In any case, this works well if your data can be treated as homogenous in this manner. Alas, it breaks down when you need to perform additional processing on certain objects before passing them on to JPA. For example, let's say I'm dealing with Books and Authors which have a many-to-many relationship. Each Book has a set of IDs referring to its authors, and each Author has a set of IDs referring to their books. Normally, JPA can manage this kind of relationship for you, but in some cases it can't (for example, the google app engine JPA provider doesn't support this). Thus, when I persist a new book for example, I may need to update the corresponding author entities. My question, then, is if there's an elegant way to handle this or if I should reconsider the sanity of my whole design. Here's a couple ways I see of dealing with it: The instanceof operator. I could use this to target certain classes when special processing is needed. Perhaps maintainability suffers and it isn't beautiful code, but if there's only 10 or so domain objects it can't be all that bad... could it? Make a different service for each entity type (ie, BookService and AuthorService). All services would inherit from a generic DataService base class and override methods if special processing is needed. At this point, you could probably also just call them DAOs instead. As always, I appreciate the help. Let me know if any clarifications are needed, as I left out many smaller details.

  • Using the JPA Criteria API, can you do a fetch join that results in only one join?

    - by Shaun
    Using JPA 2.0. It seems that by default (no explicit fetch), @OneToOne(fetch = FetchType.EAGER) fields are fetched in 1 + N queries, where N is the number of results containing an Entity that defines the relationship to a distinct related entity. Using the Criteria API, I might try to avoid that as follows: CriteriaBuilder builder = entityManager.getCriteriaBuilder(); CriteriaQuery<MyEntity> query = builder.createQuery(MyEntity.class); Root<MyEntity> root = query.from(MyEntity.class); Join<MyEntity, RelatedEntity> join = root.join("relatedEntity"); root.fetch("relatedEntity"); query.select(root).where(builder.equals(join.get("id"), 3)); The above should ideally be equivalent to the following: SELECT m FROM MyEntity m JOIN FETCH myEntity.relatedEntity r WHERE r.id = 3 However, the criteria query results in the root table needlessly being joined to the related entity table twice; once for the fetch, and once for the where predicate. The resulting SQL looks something like this: SELECT myentity.id, myentity.attribute, relatedentity2.id, relatedentity2.attribute FROM my_entity myentity INNER JOIN related_entity relatedentity1 ON myentity.related_id = relatedentity1.id INNER JOIN related_entity relatedentity2 ON myentity.related_id = relatedentity2.id WHERE relatedentity1.id = 3 Alas, if I only do the fetch, then I don't have an expression to use in the where clause. Am I missing something, or is this a limitation of the Criteria API? If it's the latter, is this being remedied in JPA 2.1 or are there any vendor-specific enhancements? Otherwise, it seems better to just give up compile-time type checking (I realize my example doesn't use the metamodel) and use dynamic JPQL TypedQueries.

  • Flash / Actionscript wheel

    - by Shaun
    Hi, I have been asked to create a wheel for navigation similar to on the Visit Provence website. However, I don't know where to start and my Googling effort have been unsuccessful - I guess that I am searching using the wrong terms. It the the way that the wheel moves and interacts with the other segments around it that interests me. I'd really appreciate any tutorials / help that anyone can share.

  • /usr/bin/python (Python 2.4) was deleted on CentOS 5. I compiled from source but yum is still broken. How can I get everything back to the way it was?

    - by Maxwell
    I saw a lot of other questions like this but none of them answered the exact part I am having trouble with (actually installing the Python RPM). Someone on my system deleted /usr/bin/python and /usr/bin/python2.4 on my 64 bit CentOS 5.8 installation. I recompiled Python 2.4 from source, but now whenever I try to yum install anything I get the following error: [root@cerulean-OW1 ~]# yum install httpd There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4 (#1, Dec 16 2012, 09:16:56) [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq I checked http://wiki.linux.duke.edu/YumFaq and it said the following: If you are getting a message that yum itself is the missing module then you probably installed it incorreclty (or installed the source rpm using make/make install). If possible, find a prebuilt rpm that will work for your system like one from Fedora or CentOS. Or, you can download the srpm and do a rpmbuild --rebuild yum*.src.rpm I tried going to http://rpm.pbone.net/index.php3/stat/4/idpl/17838875/dir/centos_5/com/python-2.4.3-46.el5.x86_64.rpm.html to install Python, which resulted in the following error: [root@cerulean-OW1 ~]# rpm -Uvh python-2.4.3-46.el5.x86_64.rpm error: Failed dependencies: python-libs-x86_64 = 2.4.3-46.el5 is needed by python-2.4.3-46.el5.x86_64 So I tried installing python-libs-x86_64, which resulted in the following: [root@cerulean-OW1 ~]# rpm -Uvh python-libs-2.4.3-46.el5_8.2.x86_64.rpm warning: python-libs-2.4.3-46.el5_8.2.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 192a7d7d Preparing... ########################################### [100%] package python-libs-2.4.3-46.el5_8.2.x86_64 is already installed file /usr/lib64/libpython2.4.so.1.0 from install of python-libs-2.4.3-46.el5_8.2.x86_64 conflicts with file from package python-libs-2.4.3-46.el5_8.2.x86_64
