  • How to specify an association relation using declarative base

    - by sam
    I have been trying to create an association relation between two tables, intake and module . Each intake has a one-to-many relationship with the modules. However there is a coursework assigned to each module, and each coursework has a duedate which is unique to each intake. I tried this but it didnt work: intake_modules_table = Table('tg_intakemodules',metadata, Column('intake_id',Integer,ForeignKey('tg_intake.intake_id', onupdate="CASCADE",ondelete="CASCADE")), Column('module_id',Integer,ForeignKey('tg_module.module_id', onupdate ="CASCADE",ondelete="CASCADE")), Column('dueddate', Unicode(16)) ) class Intake(DeclarativeBase): __tablename__ = 'tg_intake' #{ Columns intake_id = Column(Integer, autoincrement=True, primary_key=True) code = Column(Unicode(16)) commencement = Column(DateTime) completion = Column(DateTime) #{ Special methods def __repr__(self): return '"%s"' %self.code def __unicode__(self): return self.code #} class Module(DeclarativeBase): __tablename__ ='tg_module' #{ Columns module_id = Column(Integer, autoincrement=True, primary_key=True) code = Column(Unicode(16)) title = Column(Unicode(30)) #{ relations intakes = relation('Intake', secondary=intake_modules_table, backref='modules') #{ Special methods def __repr__(self): return '"%s"'%self.title def __unicode__(self): return '"%s"'%self.title #} When I do this the column duedate specified in the intake_module_table is not created. Please some help will be appreciated here. thanks in advance

  • Accessing a dictionary value by custom object value in Python?

    - by Sam
    So I have a square that's made up of a series of points. At every point there is a corresponding value. What I want to do is build a dictionary like this: class Point: def __init__(self, x, y): self._x = x self._y = y square = {} for x in range(0, 5): for y in range(0, 5): point = Point(x,y) square[point] = None However, if I later create a new point object and try to access the value of the dictionary with the key of that point it doesn't work.. square[Point(2,2)] Traceback (most recent call last): File "<pyshell#19>", line 1, in <module> square[Point(2,2)] KeyError: <__main__.Point instance at 0x02E6C378> I'm guessing that this is because python doesn't consider two objects with the same properties to be the same object? Is there any way around this? Thanks

  • MVC DateTime binding with incorrect date format

    - by Sam Wessel
    Asp.net-MVC now allows for implicit binding of DateTime objects. I have an action along the lines of public ActionResult DoSomething(DateTime startDate) { ... } This successfully converts a string from an ajax call into a DateTime. However, we use the date format dd/MM/yyyy; MVC is converting to MM/dd/yyyy. For example, submitting a call to the action with a string '09/02/2009' results in a DateTime of '02/09/2009 00:00:00', or September 2nd in our local settings. I don't want to roll my own model binder for the sake of a date format. But it seems needless to have to change the action to accept a string and then use DateTime.Parse if MVC is capable of doing this for me. Is there any way to alter the date format used in the default model binder for DateTime? Shouldn't the default model binder use your localisation settings anyway?

  • Dynamic FIFO queue

    - by sam
    Create a 4K buffer for storing 4 independent FIFO (first-in/first-out) queues of single byte character data. The organization of the FIFO should be as efficient as possible for storing the 4 queues to support dynamic (not fixed) queue size, insuring that no queue will overflow any other queue and given that it is unknown which queues may have the least # of elements and which queues may have the most # of elements.

  • Cleaning an XML file in Python before parsing

    - by Sam
    I'm using minidom to parse an xml file and it threw an error indicating that the data is not well formed. I figured out that some of the pages have characters like ไอเฟล &, causing the parser to hiccup. Is there an easy way to clean the file before I start parsing it? Right now I'm using a regular expressing to throw away anything that isn't an alpha numeric character and the </> characters, but it isn't quite working.

  • Annoying Captcha >> How to programm a form that can SMELL difference between human and robot?

    - by Sam
    Hi folks. On the comment of my old form needing a CAPTHA, I felt I share my problem, perhaps you recognize it and find its time we had better solutions: FACTUAL PROBLEM I know most of my clients (typical age= 40~60) hate CAPTCHA things. Now, I myself always feel like a robot, when I have to sueeze my eyes and fill in the strange letters from the Capcha... Sometimes I fail! Go back etc. Turnoff. I mean comon its 2011, shouldnt the forms have better A.I. by now? MY NEW IDEA (please dont laugh) Ive thought about it and this is my idea's to tell difference between human and robot: My idea is to give credibility points. 100 points = human 0% = robot. require real human mouse movements require mousemovements that dont follow any mathematical pattern require non-instantaneous reading delays, between load and first input in form when typing in form, delays are measured between letters and words approve as human when typical human behaviour measured (deleting, rephrasing etc) dont allow instant pasting or all fields give points for real keyboard pressures retract points for credibility when hyperlinks in form Test wether fake email field (invisible by human) is populated (suggested by Tomalak) when more than 75% human cretibility, allow to be sent without captcha when less than 25% human crecibility, force captcha puzzle to be sure Could we write a A.I. PHP that replaces the human-annoying capthas, meanwhile stopping most spamservers filing in the data? Not only for the fun of it, but also actually to provide a 99% better alternative than CAPTHCA's. Imagine the userfriendlyness of your forms! Your site distinguishing itself from others, showing your audience your sites KNOWS the difference between a robot and a human. Imagine the advangage. I am trying to capture the essense of that distinguishing edge. PROGRAMMING QUESTION: 1) Are such things possible to programm? 2) If so how would you start such programm? 3) Are there already very good working solutions available elsewhere? 4) If it isn't so hard, your are welcome to share your answer/solutions below. 5) upon completion of hints and new ideas, could this page be the start of a new AI captcha, OR should I forget about it and just go with the flow, forget about the whole AI dream, and use captcha like everyone else.

  • SQL Server - Query Short-Circuiting?

    - by Sam Schutte
    Do T-SQL queries in SQL Server support short-circuiting? For instance, I have a situation where I have two database and I'm comparing data between the two tables to match and copy some info across. In one table, the "ID" field will always have leading zeros (such as "000000001234"), and in the other table, the ID field may or may not have leading zeros (might be "000000001234" or "1234"). So my query to match the two is something like: select * from table1 where table1.ID LIKE '%1234' To speed things up, I'm thinking of adding an OR before the like that just says: table1.ID = table2.ID to handle the case where both ID's have the padded zeros and are equal. Will doing so speed up the query by matching items on the "=" and not evaluating the LIKE for every single row (will it short circuit and skip the LIKE)?

  • JNLP File Association: How do I open the file which was double-clicked on?

    - by Sam Barnum
    I've got the following JNLP: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE jnlp PUBLIC "-//Sun Microsystems, Inc//DTD JNLP Descriptor 6.0.10//EN" "http://java.sun.com/dtd/JNLP-6.0.10.dtd"> <jnlp spec="6.0.10" version="1.63" codebase="http://foo.example.com/msi" href="Foo.jnlp"> <information> <title>Foo</title> <vendor> Foo Systems, Inc.</vendor> <homepage href="http://Foo.com"/> <description>Foo Viewer/Editor Application</description> <icon href="splash.gif" width="425" height="102" kind="splash"/> <icon href="Foo.gif" width="64" height="64"/> <offline-allowed/> <shortcut> <desktop/> <menu submenu="Foo Systems, Inc."/> </shortcut> <association mime-type="application-x/wlog" extensions="wlog"/> <association mime-type="application-x/mplot" extensions="mplot"/> </information> <security> <all-permissions/> </security> <resources> <j2se version="1.6+" initial-heap-size="32m" max-heap-size="255m"/> <jar href="jars_deployment/TimingFramework-1.0.jar"/> <jar href="jars_deployment/iText-2.1.5.jar"/> <jar href="jars_deployment/jai_codec.jar"/> <jar href="Foo.jar"/> <jar href="jars_deployment/TimingFramework-1.0.jar"/> <jar href="jars_deployment/iText-2.1.5.jar"/> <jar href="jars_deployment/jai_codec.jar"/> <jar href="jars_deployment/jsch-20090402.jar"/> <property name="apple.laf.useScreenMenuBar" value="true"/> <property name="apple.awt.graphics.UseQuartz" value="false"/> <property name="com.apple.mrj.application.apple.menu.about.name" value="Foo"/> <property name="java.util.logging.config.file" value="/Users/Shared/logging.properties"/> </resources> <application-desc main-class="com.prosc.msi.editor.ui.test.Sandbox"/> </jnlp> Most everything is working.

I get an empty array to my application's main method. Probably unrelated, my splash screen doesn't work :( Any pointers on getting this working?

  • ruby, rails, railscasts example I messed up

    - by Sam
    If you saw the railscasts on nested forms this is the helper method to create links dynamically. However, after I upgraded to ruby 1.9.2 and rails 3 this doesn't work and I have now idea why. def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end here is the javascript function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } When I view source this is how the link is getting rendered: <p><a href="#" onclick="add_fields(this, &quot;dimensions&quot;, &quot;&quot;); return false;">Add Dimension</a></p> so &quot;&quot; is not the correct information to build a new template and something is going on with how the string for fields is getting set. such as fields= f.fields_for

  • jqGrid local date manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks

  • Reading HTTP server push streams with Python

    - by Sam
    I'm playing around trying to write a client for a site which provides data as an HTTP stream (aka HTTP server push). However, urllib2.urlopen() grabs the stream in its current state and then closes the connection. I tried skipping urllib2 and using httplib directly, but this seems to have the same behaviour. Is there a way to get the stream to stay open, so it can be checked each program loop for new contents, rather than waiting for the whole thing to be redownloaded every few seconds, introducing lag?

  • sudo taking long time

    - by Sam
    On a Ubuntu 9 64bit Linux machine, sudo takes longer time to start. "sudo echo hi" takes 2-3 minutes. strace on sudo tells poll("/etc/pam.d/system-auth", POLLIN) timesout after 5 seconds and there are multiple calls(may be a loop) to same system call (which causes 2-3min delay). Any idea why sudo has to wait for /etc/pam.d/system-auth? Any tunable to make sudo to timeout faster? Thanks Samuel
