  • Do Django Models inherit managers? (Mine seem not to)

    - by Zach
    I have 2 models: class A(Model): #Some Fields objects = ClassAManager() class B(A): #Some B-specific fields I would expect B.objects to give me access to an instance of ClassAManager, but this is not the case.... >>> A.objects <app.managers.ClassAManager object at 0x103f8f290> >>> B.objects <django.db.models.manager.Manager object at 0x103f94790> Why doesn't B inherit the objects attribute from A?

  • Eclipse: view a document using custom spacing, save using the file's spacing

    - by Steven Sproat
    I have a silly use case for eclipse: At work, they use 2 spaces for a tab character. Indentation looks really squashed and I'm finding it obstructs readability. Now, I can't set Eclipse to use 4 spaces for a tab as it'll edit any files I change, and obviously don't want to violate the coding standards. So, can I have a custom view onto my document, with saving maintaining the original spacing? Cheers

  • Python - counting sign changes

    - by dadashek
    I have a list of numbers I am reading left to right. Anytime I encounter a sign change when reading the sequence I want to count it. X = [-3,2,7,-4,1,-1,1,6,-1,0,-2,1] X = [-, +, +, -, +, -, +, +, -, -,-,+] So, in this list there are 8 sign changes. When Item [0] (in this case -3) is negative it is considered a sign change. Also, any 0 in the list is considered [-]. Any help would be greatly appreciated.

  • Has the role of the Business Analyst become redundant on true Agile projects?

    - by Joanne
    On a truely agile project where the business is performing the role of the product owner, is there still a role for the Business Analyst? The product owner would do the functional testing as soon as the user story is developed and document and prioritise the user stories. In this case which I must add I haven't experienced yet and with high performing, self motivated developers I am struggling to see the role of the traditional business analyst?

    Disclaimer: absolute novice in Scala :( I have the following defined: def tryAndReport(body: Unit) : Unit = { try { body } catch { case e: MySpecificException => doSomethingUseful } } I call it like this: tryAndReport{ someCodeThatThrowsMySpecificException() } While the call to someCodeThatThrowsMySpecificException happens just fine, the exception is not being caught in tryAndReport. Why? Thank you!

  • How to with extract url from tweet using Regular Expressions

    - by neutreno
    Ok so i'm executing the following line of code in javascript RegExp('(http:\/\/t.co\/)[a-zA-Z0-9\-\.]{8}').exec(tcont); where tcont is equal to some string like 'Test tweet to http://t.co/GXmaUyNL' (the content of a tweet obtained by jquery). However it is returning, in the case above for example, 'http://t.co/GXmaUyNL,http://t.co/'. This is frustracting because I want the url without the bit on the end - after and including the comma. Any ideas why this is appearing? Thanks

  • Semantic urls with dots in .net

    - by Jokin
    I'm trying to make semantic urls for search pages, but if someone use a search finished in dot, the .net engine return a 404. The request don't even get to the routing engine, so i think its something related to security or something like that. For example, the stackoverflow routes also don't work in these case: http://stackoverflow.com/questions/tagged/etc.

  • SEO difference between dash and hypen

    - by FFish
    I understand with dashes once can search for keywords in different order. What if my keyword has a space in it like real estate or New York Should I use underscores in this case?

  • JBoss Service with SSL and Protocol Buffers

    - by mlaverd
    Hello everyone, I'm interested in building a JBoss service. Because I'm reusing some existing code, the service must be able to talk SSL/TLS and Protocol Buffers. The documentation I see on the JBoss wiki makes it look like services have their transport and data interpretation handled by JBoss itself. Is it really the case? How could I implement this requirement? Regards, M-A

  • Installing Ruby 1.9.1 on Ubuntu?

    - by Björn
    I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files? So I think I need some way to tell Ubuntu that Ruby is in fact already installed?

    - by Daan van Yperen
    Because my time is limited I can usually only focus on one or two of my hobby projects, while the others sit there wasting away. I am looking for a solution that would allow me to divide my time better. is open sourcing where I take the role of guiding the project realistic, or are there better solutions? In my case, one project has a reasonably sized community of users going for it but is currently closed source. There have been requests to open source it.

  • Oracle : Identifying duplicates in a table without index

    - by user288031
    When I try to create a unique index on a large table, I get a unique contraint error. The unique index in this case is a composite key of 4 columns. Is there an efficient way to identify the duplicates other than : select col1, col2, col3, col4, count() from Table1 group by col1, col2, col3, col4 having count() 1 The explain plan above shows full table scan with extremely high cost, and just want to find if there is another way. Thanks !
