  • Is there a way to create a python object that will be not sortable?

    - by Graf
    Is there a possibility to create any python object that will be not sortable? So that will be an exception when trying to sort a list of that objects? I created a very simple class, didn't define any comparison methods, but still instances of this class are comparable and thus sortable. Maybe, my class inherits comparison methods from somewhere. But I don't want this behaviour.

Can someone give me an code example where this fails?

    - by Duane Hilton
    I'm trying to create a Django app that would take an inputted address and return a list of political races that person would vote in. I have maps of all the districts (PDFs). And I know that I can use geopy to convert an inputted address into coordinates. How do I define the voter districts in Django so that I can run a query to see what districts those coordinates fall in?

    I'm trying to create an image rotator class that cycles through an arbitrary number of images in an unordered list. Is it possible to define a recursive function within a class declaration?

  • Basic Database Design

    - by Thurein
    Hi, This question would be a bit childish, I have three tables, users, usergroups and contacts. In my system, the end user can create a contact and subsequently he\she may define the visibility of the contact by setting only for that user, or for a set of users or a set of usergroups. So I am wondering, how my database design would be, it should be many to many between users and contacts or many to many between usergroups and contacts. Definitely there is a one to many relationship between users and usergroups. Thanks Thurein

  • NSIS - put EXE version into name of installer

    - by codeulike
    NSIS has a Name variable that you define in the script: Name "MyApp" It defines the name of the installer, that gets displayed as the window title, etc. Is there a way to pull the .NET Version number out of my main EXE and append it to the Name? So that my installer name would automatically be 'MyApp V2.2.0.0" or whatever?

  • How do I design this link table?

    - by Soo
    Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

  • Acl mechanism for JSF

    - by michael lucas
    Is there some ready-to-use ACL mechanism for JSF? I know JBoss Seam comes with something like that, but switching to JBoss Seam is not an option in my case. What I need is to easily define which pages given user is allowed to see and which actions to invoke.

  • Anyone know of a Java reporting tools which has a web based visual report designer?

    - by kwyjibo
    We're currently evaluating different Java reporting engines, and having a web-based ad-hoc report designer is a requirement. We don't need anything too fancy, but we need users to be able to define a report with columns X, grouped by Y, sorted by Z, etc... We've found that many of the open source tools do have graphical report designers, but the designers are typically not web based. (For example, iReport from JasperReports seems to be an application, not a web tool) Can anyone recommend a reporting tool which meets this web-based requirement?

  • CSS: What is the proper way to deal with multiple classes of Text

    - by DavidR
    So I'm on commission for a website, and I'm trying to improve my code. When dealing with a website with multiple types of font (here it's large, there it's small, there it's bold, here it's underlined, etc.) is this where we use the h1-h6, or do we reserve those for times when there is a definite hierarchy, using instead <p class="xxx"> to define different classes for text?

  • JSDoc3: How to document a AMD module that returns a function

    - by Jens Simon
    I'm trying to find a way to document AMD modules using JSDoc3. /** * Module description. * * @module path/to/module */ define(['jquery', 'underscore'], function (jQuery, _) { /** * @param {string} foo Foo-Description * @param {object} bar Bar-Description */ return function (foo, bar) { // insert code here }; }); Sadly none of the patterns listed on http://usejsdoc.org/howto-commonjs-modules.html work for me. How can I generate a proper documentation that lists the parameters and return value of the function exported by the module?

  • buffer size for socket connection in c++

    - by wyatt
    I'm trying to build a basic POP3 mail client in C/++, but I've run into a bit of an issue. Since you have to define the buffer size when building the program, but a message can be arbitrarily large, how do you, say, get the mail server to send it to you in parts? And if this isn't the correct means of solving the problem, what is? And while I'm here, can anyone confirm for me that RFC 2822 is still the current document defining email layout? Thanks

  • PostgreSQL, triggers, and concurrency to enforce a temporal key

    - by Hobbes
    I want to define a trigger in PostgreSQL to check that the inserted row, on a generic table, has the the property: "no other row exists with the same key in the same valid time" (the keys are sequenced keys). In fact, I has already implemented it. But since the trigger has to scan the entire table, now i'm wondering: is there a need for a table-level lock? Or this is managed someway by the PostgreSQL itself?
