  • Sorting Table Cells based on data from NSArray

    - by Graeme
    Hi, I have an NSArray which contains information from an RSS feed on dogs, such as [dog types], [dog age] and [dog size]. At the moment my UITableView simply displays each cell on each dog and within the cell lists [dog types], [dog age] and [dog size]. I want to be able to allow users of my app to "sort" this data based on the dog name, dog size or dog age when they press a UIButton in the top nav-bar. I'm struggling to work out how to filter the UITableView based on these factors, so any help is appreciated. Thanks.

  • Castle ActiveRecord Table name conflict

    - by Shane
    When you run into a reserved word like "User" in NHibernate you would just put single quotes around the offending text and nHibernate will surround the text with square brackets for querying. My question is how do you do the same thing using Castle.ActiveRecord?

  • how to number t-rows ,when table generated using nested forloop in django templates

    - by stackover
    Hi, This part is from views.py results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])] for tup in results: total = tot+len(tup[1]) render_to_response(url,{'results':res , 'total':str(tot),}) this is template code: <th class="name">Name</th> <th class="id">Student ID</th> <th class="grade">Grade</th> {% for tup in results %} {% for student in tup|last %} {% with forloop.parentloop.counter as parentid%} {% with forloop.counter as centerid%} <tbody class="results-body"> <tr> <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td> <td>{{student.id}}</td> <td>{{tup|first}}</td> </tr> {% endfor %} {% endfor %} Now the problems am having are 1. numbering the rows. Here my problem is am not sure if i can do things like total=total-1 in the templates to get the numbered rows like <td>{{total}}</td> 2.applying css to tr:ever or odd. Whats happening in this case is everytime the loop is running the odd/even ordering is lost. these seems related problems. Any ideas would be great :)

  • Editting ForeignKey from "child" table

    I'm programming on py with django. I have models: class Product(mymodels.Base): title = models.CharField() price = models.ForeignKey(Price) promoPrice = models.ForeignKey(Price, related_name="promo_price") class Price(mymodels.Base): value = models.DecimalField(max_digits=10, decimal_places=3) taxValue = models.DecimalField("Tax Value", max_digits=10, decimal_places=3) valueWithTax = models.DecimalField("Value with Tax", max_digits=10, decimal_places=3) I want to see INPUTs for both prices when editing product, but cannot find any possibility to do that. inlines = [...] works only from Price to Product, which is stupid in this case. Thanx for adnvance.

  • Read tab delimited text file into MySQL table with PHP

    - by Simon S
    I am trying to read in a series of tab delimited text files into existing MySQL tables. The code I have is quite simple: $lines = file("import/file_to_import.txt"); foreach ($lines as $line_num => $line) { if($line_num > 1) { $arr = explode("\t", $line); $sql = sprintf("INSERT INTO my_table VALUES('%s', '%s', '%s', %s, %s);", trim((string)$arr[0]), trim((string)$arr[1]), trim((string)$arr[2]), trim((string)$arr[3]), trim((string)$arr[4])); mysql_query($sql, $database) or die(mysql_error()); } } But no matter what I do (hence the casting before each variable in the sprintf statement) I get the "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1" error. I echo out the code, paste it into a MySQL editor and it runs fine, it just won't execute from the PHP script. What am I doing wrong?? Si

  • Returning a shared library symbol table

    - by joemoe
    For instance: void* sdl_library = dlopen("libSDL.so", RTLD_LAZY); void* initializer = dlsym(sdl_library,"SDL_Init"); Assuming no errors, initializer will point to the function SD_Init in the shared library libSDK.so. However this requires knowing the symbol "SDL_Init" exists. Is it possibly to query a library for all its symbols? Eg, in this case it would return SDL_Init, the function pointer, and any other symbols exported by libSDL.so.

  • free public databases with non-trivial table structures?

    - by Caffeine Coma
    I'm looking for some sample database data that I can use for testing and demonstrating a DB tool I am working on. I need a DB that has (preferably) many tables, and many foreign key relationships between the tables. Ideally the data would be in SQL dump format, or at least in something that maintains the foreign key references, and could be easily import into an RDBMS (MySQL or H2). The dataset itself doesn't have to be huge (in fact, best if it's not). I thought about using the Stackoverflow Data Dump, but it's only about 5 tables.
