  • Creating a structure from bytes with ctypes and IronPython

    - by Adal
    I have the following CPython code which I now try to run in IronPython: import ctypes class BarHeader(ctypes.Structure): _fields_ = [ ("id", ctypes.c_char * 4), ("version", ctypes.c_uint32)] bar_file = open("data.bar", "rb") header_raw = bar_file.read(ctypes.sizeof(BarHeader)) header = BarHeader.from_buffer_copy(header_raw) The last line raises this exception: TypeError: expected array, got str I tried BarHeader.from_buffer_copy(bytes(header_raw)) instead of the above, but then the exception message changes to TypeError: expected array, got bytes. Any idea what I'm doing wrong?

  • Symfony2 Entity to array

    - by Adriano Pedro
    I'm trying to migrate my flat php project to Symfony2, but its coming to be very hard. For instance, I have a table of Products specification that have several specifications and are distinguishables by its "cat" attribute in that Extraspecs DB table. Therefore I've created a Entity for that table and want to make an array of just the specifications with "cat" = 0... I supose the code is this one.. right? $typeavailable = $this->getDoctrine() ->getRepository('LabsCatalogBundle:ProductExtraspecsSpecs') ->findBy(array('cat' => '0')); Now how can i put this in an array to work with a form like this?: form = $this ->createFormBuilder($product) ->add('specs', 'choice', array('choices' => $typeavailableArray), 'multiple' => true) Thank you in advance :) # Thank you all.. But now I've came across with another problem.. In fact i'm building a form from an existing object: $form = $this ->createFormBuilder($product) ->add('name', 'text') ->add('genspec', 'choice', array('choices' => array('0' => 'None', '1' => 'General', '2' => 'Specific'))) ->add('isReg', 'choice', array('choices' => array('0' => 'Material', '1' => 'Reagent', '2' => 'Antibody', '3' => 'Growth Factors', '4' => 'Rodents', '5' => 'Lagomorphs'))) So.. in that case my current value is named "extraspecs", so i've added this like: ->add('extraspecs', 'entity', array( 'label' => 'desc', 'empty_value' => ' --- ', 'class' => 'LabsCatalogBundle:ProductExtraspecsSpecs', 'property' => 'specsid', 'query_builder' => function(EntityRepository $er) { return $er ->createQueryBuilder('e'); But "extraspecs" come from a relationship of oneToMany where every product has several extraspecs... Here is the ORM: Labs\CatalogBundle\Entity\Product: type: entity table: orders__regmat id: id: type: integer generator: { strategy: AUTO } fields: name: type: string length: 100 catnumber: type: string scale: 100 brand: type: integer scale: 10 company: type: integer scale: 10 size: type: decimal scale: 10 units: type: integer scale: 10 price: type: decimal scale: 10 reqcert: type: integer scale: 1 isReg: type: integer scale: 1 genspec: type: integer scale: 1 oneToMany: extraspecs: targetEntity: ProductExtraspecs mappedBy: product Labs\CatalogBundle\Entity\ProductExtraspecs: type: entity table: orders__regmat__extraspecs fields: extraspecid: id: true type: integer unsigned: false nullable: false generator: strategy: IDENTITY regmatid: type: integer scale: 11 spec: type: integer scale: 11 attrib: type: string length: 20 value: type: string length: 200 lifecycleCallbacks: { } manyToOne: product: targetEntity: Product inversedBy: extraspecs joinColumn: name: regmatid referencedColumnName: id HOw should I do this? Thank you!!!

  • Automatic database generation / migration with perl

    - by pistacchio
    Hi, In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any perl module that does the same? Eg, it takes the YAML / XML / JSON description of a database as input and modifies / generates the database accordingly? Thanks in advance.

  • what's the right way to bind sqldatasource to asp:label in asp.net 4.0?

    - by cskilbeck
    Is it possible using Eval? If so, can someone post a short fragment to illustrate? My SqlDataSource returns 1 record with 3 fields, I'd like to Format these into a string. eg: Record Field 'Name' = 'Jack' Field 'Amount' = 100 Field 'Date' = 12.02.2010 asp:Label text should end up being: Welcome Jack, last payment was 100 on 12.02.2010 if another control than asp:Label is appropriate, that would be good to know also.

  • How to find out whether SqlCe query Has rows?

    - by Tomas
    Hi, In my simple db I use SqlCe and I cannot figure out how to correctly find out whether the query has rows or not. HasRows does not work. So far I have this: _DbCommand.CommandText="SELECT * FROM X" SqlCeDataReader reader=_DbCommand.ExecuteQuery(); if (reader.FieldCount!=0) //I thought it could work (O rows - 0 fields?), but its true even with 0 rows { while (reader.Read()) { // } } Thanks

  • Sticky Footers that move down when dynamic content gets loaded

    - by Dominic Rodger
    I've been using this snippet of jQuery to get a sticky footer: if($(document.body).height() < $(window).height()){ $("#footer").css({position: "absolute",top:($(window).scrollTop()+$(window).height()-$("#footer").height())+"px", width: "100%"}); } $(window).scroll(positionFooter).resize(positionFooter); However, that breaks when I've got expandable/collapsible divs lying around where the original content was less high than the window, since it is then stuck to the bottom of the window, rather than the bottom of the document. Is there a way of fixing this, or a better way of doing it? Please bear in mind that I don't have much control over the HTML, since I need to do this in Django's admin interface, which doesn't allow much injection of HTML in the places you might want to to accomplish this sort of thing (i.e. this answer and this answer don't work for me).

  • How to update a collection based on another collection in MongoDB?

    - by Sean Zhu
    Now I get two collections: coll01 and coll02. And the structure of coll01 is like this: { id: 01, name: "xxx", age: 30 } and the structure of coll02 is like: { id: 01, name: "XYZ" gender: "male" } The two id fields in the both collection are indices. And the numbers of documents in these two collections are same. And what I want to do in traditional SQL is : update coll01, coll02 set coll01.name = coll02.name where coll01.id = coll02.id

  • Specify ApplicationName when using ASP.NET Web Site Administration Tool

    - by ProfK
    This tool is supposed to configure users and roles etc., but when I use it on a new web site, with a new aspnetdb database, it adds a record to the aspnet_Applications table with the ApplicationName and the LoweredApplicationName fields set to /. I think it would make more sense if it actually used the application name, i.e. the web site name. Can I safely just change the application name? Is there a better way of configuring these things?

  • Python Scraper for Javascript?

    - by Diego
    Hey all, Can anyone direct me to a good Python screen scraping library for javascript code (hopefully one with good documentation/tutorials)? I'd like to see what options are out there, but most of all the easiest to learn with fastest results... wondering if anyone had experience. I've heard some stuff about spidermonkey, but maybe there are better ones out there? Specifically, I use BeautifulSoup and Mechanize to get to here, but need a way to open the javascript popup, submit data, and download/parse the results in the javascript popup. <a href="javascript:openFindItem(12510109)" onclick="s_objectID=&quot;javascript:openFindItem(12510109)_1&quot;;return this.s_oc?this.s_oc(e):true">Find Item</a> I'd like to implement this with Google App engine and Django. Thanks!

  • Python `.pth` files and using relative paths

    - by kRON
    I have a lot of development versions of packages installed with virtualenv under the default /src directory in the environment. Normally, I decided to do the development of my project under the /src directory afterwards. To add my directory to the Python path, I decided to eschew from using any absolute paths, since I'm going to have to move the project around with my friends. It's a Django application, so I was happy with putting environment.pth under the root that contained the path to my project and a wsgi in the same directory would call the sites module to parse environment.pth. All good. I was also looking to move the .pth file into site-packages, but I'm having trouble with relative paths that move up the directory tree. For: /env /lib /site-pacakges /src /myproject So, the .pth entry in site-packages to myproject should look like ../../src/myproject, but this doesn't seem to be working for me on Windows.

  • JQuery username validation - Ajax call

    - by Denise
    Hi, I am currently using JQuery's validation plugin for basic form validation such as required fields.

My requirements are: Preferably integrate with JQuery Validation plugin, rather than writing a custom function I want the lookup to occur on the nkeyup event I want the lookup to be triggered approx 0.5 seconds after the keyup event has occurred. Thanks!

  • Basic Custom String Class for C++

    - by wdow88
    Hey all, I'm working on building my own string class with very basic functionality. I am having difficulty understand what is going on with the basic class that I have define, and believe there is some sort of error dealing with the scope occurring. When I try to view the objects I created, all the fields are described as (obviously bad pointer). Also, if I make the data fields public or build an accessor method, the program crashes. For some reason the pointer for the object is 0xccccccccc which points to no where. How can a I fix this? Any help/comments are much appreciated. //This is a custom string class, so far the only functions are //constructing and appending #include<iostream> using namespace std; class MyString1 { public: MyString1() { //no arg constructor char *string; string = new char[0]; string[0] ='\0'; std::cout << string; size = 1; } //constructor receives pointer to character array MyString1(char* chars) { int index = 0; //Determine the length of the array while (chars[index] != NULL) index++; //Allocate dynamic memory on the heap char *string; string = new char[index+1]; //Copy the contents of the array pointed by chars into string, the char array of the object for (int ii = 0; ii < index; ii++) string[ii] = chars[ii]; string[index+1] = '\0'; size = index+1; } MyString1 append(MyString1 s) { //determine new size of the appended array and allocate memory int newsize = s.size + size; MyString1 MyString2; char *newstring; newstring = new char[newsize+1]; int index = 0; //load the first string into the array while (string[index] != NULL) { newstring[index] = string[index]; index++; } //load the second string while (s.string[index] != NULL) { newstring[index] = s.string[index]; index++; } //null terminate newstring[newsize+1] = '\0'; delete string; //generate the object for return MyString2.string=newstring; MyString2.size=newsize; return MyString2; } private: char *string; int size; }; int main() { MyString1 string1; MyString1 string2("Hello There"); MyString1 string3("Buddy"); string2.append(string3); return 0; }

  • correct approach to store in database

    - by John
    I'm developing an online website (using Django and Mysql). I have a Tests table and User table. I have 50 tests within the table and each user completes them at their own pace. How do I store the status of the tests in my DB? One idea that came to my mind is to create an additional column in User table. That column containing testid's separated by comma or any other delimiter. userid | username | testscompleted 1 john 1, 5, 34 2 tom 1, 10, 23, 25 Another idea was to create a seperate table to store userid and testid. So, I'll have only 2 columns but thousands of rows (no of tests * no of users) and they will always continue to increase. userid | testid 1 1 1 5 2 1 1 34 2 10

  • nginx improperly forwards to https, adds two trailing slashes when rewriting

    - by Kevin
    I'm using nginx as a proxy for a django project on mod_wsgi and to serve the static content. I have two domain names for it: asdf-example.com and asdfexample.com. I want to use rewrites to redirect everything to www.asdf-example.com They're not quite working the way they should: asdf-example.com forwards to https:// www.asdf-example.com, which fails because I'm not using SSL. Though asdf-example.com/search forwards to http://.... asdfexample.com and www.asdfexample.com both forward to www.asdf-example.com//, which looks weird. My config file: server { listen 80; server_name asdf-example.com asdfexample.com; if ($host ~* ^asdf-example\.com){ rewrite ^(.*)$ http://www.asdf-example.com/$1 permanent; } if ($host ~* ^asdfexample\.com){ rewrite ^(.*)$ http://www.asdf-example.com/$1 permanent; } if ($host ~* ^www\.asdfexample\.com){ rewrite ^(.*)$ http://www.asdf-example.com/$1 permanent; } ...
