• How to read back and print text with newlines from a Python (Django) string with HTML?

  - by user1801486

  If someone types in a phrase, such as: I see you driving round town with the girl I love, and I’m like: haiku. (no blank lines between each line, but the text is written on three separate lines) into a text box on a web page, and then presses a button which is then stored in a database via Django, and that string is read back and printed on a page, how can I get it to print on an HTML page with the newlines still in the text? So instead of it being printed back as: I see you driving round town with the girl I love, and I’m like: haiku. It would print as: I see you driving round town with the girl I love, and I’m like: haiku. I know that if I use: (textarea)soAndSo.body(/textarea), this preserves the newlines that were in the file when the user typed it up originally. How can I get this same effect, but without having to use textarea boxes?

• Why is this MySQL Join Statement not Working?

  - by Timmy

  Here is my code: $query2 = mysql_query("SELECT * FROM categories WHERE parent = $id JOIN SELECT * FROM posts WHERE main_nav_page = '$idTwo'"); while ($row2 = mysql_fetch_assoc($query2)) { $id = $row2['id']; $name = $row2['name']; $slug = $row2['slug']; $subMenuOrder = $row2['sub_menu_order']; echo "<tr>\n"; echo "<td>&nbsp; -- $name</td>\n"; echo "</tr>\n"; } Is my syntax wrong? EDIT: the error message is: Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/studentw/public_html/new_nav.php on line 30

• Delete NSManageObject at the event tableView:commiteEditingStyle:forRowAtIndexPath:

  - by David.Chu.ca

  I got exception when I tried to delete one NSManageObject at the event of tableView:commiteEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting?

• "Zoom" text to be as big as possible within constraints/box

  - by stolsvik

  First problem: You have 400 pixels width to go on, and need to fit some text within that constraint as large as possible (thus, the text shall use that amount of space). Throw in a new constraint: If the text is just "A", then it shall not zoom this above 100 pixels (or some specific font size). Then, a final situation: Linebreaks. Fit some text in the largest possible way within e.g. 400 x 150 pixels. An obvious way is to simply start with point 1, and then increase until you can't fit it anymore. This would work for all three problems, but would be very crude. The fitting of a single line within bounds could be done by writing it with some fixed point size, check the resulting pixel bounds of the text, and then simply scale it with a transform (the text scales properly too then, check out TransformUI). Any ideas of other ways to attack this would be greatly appreciated!

• Semicolon in object variable name

  - by milkfilk

  There's a common LDAP attribute called userCertificate;binary. It actually has a semi-colon in the attribute name. In ruby, I turn an LDAP entry into a OpenStruct object called 'struct'. struct.class = OpenStruct But of course ruby thinks it's an end-of-line character. ? struct.userCertificate;binary NameError: undefined local variable or method `binary' for main:Object from (irb):52 from :0 IRB knows that the local variable is there, because it gives me struct.userCertificate;binary from the tab auto-completion. I can also see the class variable when calling struct.methods on it. struct.methods = ... "send", "methods", "userCertificate;binary=", "hash", ... It's definitely there, I can see the contents if I print the whole variable to_s(). But how can I access the local variable when it has a semicolon in it? I have workarounds for this but I thought it was an interesting problem to post.

• Problem with SQLite executemany

  I can't find my error in the following code.

• Call to a member function query() on a non-object

  - by Randy Gonzalez

  Ok, this is so weird!!! I am running PHP Version 5.1.6 when I try and run the code below it gives a fatal error of an object that has not been instantiated. As soon as I un-comment this line of code //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); everything works. Even though I have declared the $cb_db object as global within in the method. Any help would be greatly appreciated. require_once ( ROOT_CB_CLASSES . 'db.php'); $cb_db = new cb_db(USER, PASSWORD, NAME, HOST); class cb_user { protected function find_by_sql( $sql ) { global $cb_db; //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); $result_set = $cb_db->query( $sql ); $object_array = array(); while( $row = $cb_db->fetch_array( $result_set ) ) { $object_array[] = self::instantiate( $row ); } return $object_array; } }

• Which field is explain telling me to index?

  - by shady

  I don't understand what this explain statement is saying. Which field needs an index?. The first line to me is confusing because ref is null. Here's the query I'm using: SELECT pp.property_id AS 'good_prop_id', pr.site_number AS 'pr.site_number', CONCAT(pr.site_street_name, ' ', pr.site_street_type) AS 'pr.partial_addr', pr.county FROM realval_newdb.preforeclosures AS pr INNER JOIN realval_newdb.properties_preforeclosures AS pp USE INDEX (mee_id) ON (pr.mee_id = pp.mee_id) INNER JOIN listings_copy AS lc ON (pr.site_number = lc.site_number) AND (lc.site_street_name = CONCAT(pr.site_street_name, ' ', pr.site_street_type)) WHERE lc.site_county = pr.county LIMIT 1; Can anyone help me optimize this query?

• Find a part of UNC path and put in a variable?

  - by Refracted Paladin

  I am trying to peel off the last part of a unc path that is being passed and put it in a variable to use in a method further down the line. Example path would be -- \\ourfileserver\remoteuploads\countyfoldername\personfoldername How do I peel just the countyfoldername out of that? I had thought to try var th = e.FullPath.LastIndexOf('\\'); var whichFolder = folderPath.Substring(th); but that is an escape character and it doesn't like @ either. Is this even the right direction?

• Breaking the loop in Jython

  - by kdev

  Hi everyone, I have a written a loop for and if condition and I want to break to loop completely when if gets satisfied. while count: i=0 for line in read_record: #print str.strip(count[1:28]) #print str.strip(read_record[i]) if string.find(str.strip(read_record[i]),str.strip(count[1:28]))>0: code=str.strip(read_record[i+19])+str.strip(read_record[i+20]) print code[25:] break i=i+1 So here if the if string.find condition gets satisfied I want to go to while loop flow. Please tell me what will be the best place to break and how should I modify the program so that once the if condition is satisfied I am out of the loop and start again with while loop.

• Padding/Margin/Border On Element Does Not Change DIV Height

  - by ryandlf

  Here is a very simply jsFiddle to demonstrate my problem: http://jsfiddle.net/ryandlf/mSmUv/4/ When an element has a top padding or margin and it sits on the first line within a div, the div does not respect that padding or margin and push the element down. In most cases this isn't an issue, but for example, if I have a button that has a top border and padding the top of the border will be cut off because the div is not taking into consideration the padding value. Is there a workaround for this other than just blindly setting margins or padding on every container div element and hoping I have added enough to account for any internal element that might be affected?

• Why is an anonymous inner class containing nothing generated from this code?

  - by Andrew Westberg

  When run through javac on the cmd line Sun JVM 1.6.0_20, this code produces 6 .class files OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When run through JDT in eclipse, it produces only 5 classes. OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When decompiled, OuterClass$1.class contains nothing. Where is this extra class coming from and why is it created? package com.test; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } public class InnerClass2 { } //this class should not exist in OuterClass after dummifying private class PrivateInnerClass { private String getString() { return "hello PrivateInnerClass"; } } public String getStringFromPrivateInner() { return new PrivateInnerClass().getString(); } }

• How can I plot a time series graph with Perl?

  - by Jazz

  I have some data from a database (SQLite), mapping a value (an integer) to a date. A date is a string with this format: YYYY-MM-DD hh:mm. The dates are not uniformly distributed. I want do draw a line graph with the dates on X and the values on Y. What is the easiest way to do this with Perl? I tried DBIx::Chart but I could not make it recognize my dates. I also tried GD::Graph, but as the documentation says: GD::Graph does not support numerical x axis the way it should. Data for X axes should be equally spaced

• Valid HTTP header? `GET /page.html Http1.0`?

  - by Earlz

  Ok so I've been reading up on HTTP and found this page. This is an example HTTP request that was posted there: GET /http.html Http1.1 Host: www.http.header.free.fr Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, Accept-Language: Fr Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0) Connection: Keep-Alive I tried it in telnet and it worked. But everywhere else I see this kind of request line GET /http.html HTTP/1.1 The important different is that HTTP is all caps and the / character. Are they both correct? They both seem to work on the sites I've tested it on. I've skimmed the RFC of HTTP but didn't find anything of use. Has anyone else seen this kind of request header? Is it officially supported?

• Automatically decorating every instance method in a class

  - by max

  I want to apply the same decorator to every method in a given class, other than those that start and end with __. It seems to me it should be doable using a class decorator. Are there any pitfalls to be aware of? Ideally, I'd also like to be able to: disable this mechanism for some methods by marking them with a special decorator enable this mechanism for subclasses as well enable this mechanism even for methods that are added to this class in runtime [Note: I'm using Python 3.2, so I'm fine if this relies on features added recently.] Here's my attempt: _methods_to_skip = {} def apply(decorator): def apply_decorator(cls): for method_name, method in get_all_instance_methods(cls): if (cls, method) in _methods_to_skip: continue if method_name[:2] == `__` and method_name[-2:] == `__`: continue cls.method_name = decorator(method) return apply_decorator def dont_decorate(method): _methods_to_skip.add((get_class_from_method(method), method)) return method Here are things I have problems with: how to implement get_all_instance_methods function not sure if my cls.method_name = decorator(method) line is correct how to do the same to any methods added to a class in runtime how to apply this to subclasses how to implement get_class_from_method

• Having trouble with post-commit hook

  - by John Isaacks

  I am following this tutorial that is like the hello world for post-commit I am using unbuntu 10.04. I installed svnnotify and ran $ which svnnotify which output: /usr/bin/svnnotify so I changed the path in the turorial from /usr/local/bin/svnnotify to /usr/bin/svnnotify I also tried changing the line: #!/bin/sh to #!/bin/bash since bash is the login shell in ubuntu 10.04. I tried to run it the way the tutorial originally had it, with my changes, and combinations of the two. Everytime the commit is successful but I get Warning: post-commit hook failed (exit code 1) with no output. The original way had output not found I am very new to linux and shell scripting and have exhausted everything I can think of. What am I doing wrong?

• How do i create a nice looking image fadein onload with mootools?

  - by woobione

  Hi everyone! I´m creating a website for a photographer who would like a fine fadein on his images. I have excluded flash as a solution and would like to use those fine-looking effects of mootools fx. But the problem is that I'm really lousy when it comes to javascript. So if anyone could give me an easy solution for fading in one single image onload and when the image is loaded I would be really happy. I know there is a lot of different people out there who have this. But the problem is that i don't know how the code works even if it is a complete solution. So most important. If anyone has got the time to explain what every single line of code does i would be more than grateful. Thanks!

• Parameter passed by const reference returned by const reference.

  - by Alien01

  Hello, I was reading C++ Faq Second Edition , faq number 32.08 . FAQ says that parameter passed by const reference and returned by const reference can cause dangling reference. But it is ok if parameter is passed by reference and returned by reference. I got it that it is unsafe in case of const reference but how is it safe in case when parameter is non const reference. Last line of FAQ says "Note that if a function accepts a parameter by non-const reference (for example, f(string& s)), returning a copy of this reference parameter is safe because a temporary cannot be passed by non-const reference." Need some insight on this!!

• SELECT with a Replace()

  I have a table of names and addresses, which includes a postcode column. I want to strip the spaces from the postcodes and select any that match a particular pattern. I'm trying this (simplified a bit) in T-SQL on SQL Server 2005: SELECT Replace(Postcode, ' ', '') AS P FROM Contacts WHERE P LIKE 'NW101%' But I get the following error; Msg 207, Level 16, State 1, Line 3 Invalid column name 'P'. If I remove the WHERE clause I get a list of postcodes without spaces, which is what I want to search. How should I approach this? What am I doing wrong?

The problem I am facing is that during subsequent assignment of text if the size of the label changes, happens when images have been successfully loaded the label does not render properly but rather blanks out. But I see the proper label when is scroll and come back to the cell again.
