• Convert PostgreSQL array to PHP array

  - by EarthMind

  I have trouble reading Postgresql arrays in PHP. I have tried explode(), but this breaks arrays containing commas in strings, and str_getcsv() but it's also no good as PostgreSQL doesn't quote the Japanese strings. Not working: explode(',', trim($pgArray, '{}')); str_getcsv( trim($pgArray, '{}') );

• JPA Secondary Table Issue

  - by Smithers

  I have a three tables: User, Course, and Test. Course has a User foreign key and Test has a Course foreign key. I am having trouble mapping the Test collection for each User since I need an intermediary step from User - Course - Test. I am trying to use a SecondaryTable since the User key for the Test is its associated Course row. Am I on the right track using SecondaryTable or is there a way to use a JoinTable without the inverseJoinColumn?

  - by Brian515

  Hi all, I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean: SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); boolean autoreplyon = settings.getBoolean("autoreplyon", false); However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class). Thanks in advance for any suggestions!

• Drupal: Convert taxonomy term name to term id

  - by gigantorTRON

  Using 'taxonomy: term ID' as an argument in one of my Drupal views and I'm having trouble getting it to work correctly. On the views administration page it states, "if using term name, it is generally more efficient to convert it to a term ID and use Taxonomy: Term ID rather than Taxonomy: Term Name." How does one go about converting the term name from a URL into a term ID?

• Codeigniter: Submitting Forms

  - by Kevin Brown

  How do I submit a form that can do two different things based on the URI? For example, if the URI contains a string "new" the form will submit differently than it would if "new" were not in the URI. I'm having trouble implementing this, as when a form is submitted, it takes the URI of whatever "form_open" says.

• Compile/use unrar C++ source for iphone app?

  - by greypoint

  Writing an app that will include the ability to decompress zip and rar files. I think I'm OK on how to handle the .zips but .rars seem a little more trouble. I noticed that rarlabs has source available but it's C++. Is there a way to compile, wrap or otherwise use this code within an iPhone app? Reference: http://www.rarlab.com/rar_add.htm Open to alternate suggestions on how to handle .rar files as well. I'm still pretty much a newbie so please explain in small words :)

• Reporting Services Matrix Order

  - by James Stewart

  I've got a reporting services report which display data in a matrix. The matrix rows are ordered by the report on a specific field's value. Trouble is I want a particular value to always appear last in the matrix even though it won't naturally be ordered there. Is there a way I can do this using an expression? Thanks.

• Speeding up templates in GAE-Py by aggregating RPC calls

  - by Sudhir Jonathan

  Here's my problem: class City(Model): name = StringProperty() class Author(Model): name = StringProperty() city = ReferenceProperty(City) class Post(Model): author = ReferenceProperty(Author) content = StringProperty() The code isn't important... its this django template: {% for post in posts %} <div>{{post.content}}</div> <div>by {{post.author.name}} from {{post.author.city.name}}</div> {% endfor %} Now lets say I get the first 100 posts using Post.all().fetch(limit=100), and pass this list to the template - what happens? It makes 200 more datastore gets - 100 to get each author, 100 to get each author's city. This is perfectly understandable, actually, since the post only has a reference to the author, and the author only has a reference to the city. The __get__ accessor on the post.author and author.city objects transparently do a get and pull the data back (See this question). Some ways around this are Use Post.author.get_value_for_datastore(post) to collect the author keys (see the link above), and then do a batch get to get them all - the trouble here is that we need to re-construct a template data object... something which needs extra code and maintenance for each model and handler. Write an accessor, say cached_author, that checks memcache for the author first and returns that - the problem here is that post.cached_author is going to be called 100 times, which could probably mean 100 memcache calls. Hold a static key to object map (and refresh it maybe once in five minutes) if the data doesn't have to be very up to date. The cached_author accessor can then just refer to this map. All these ideas need extra code and maintenance, and they're not very transparent. What if we could do @prefetch def render_template(path, data) template.render(path, data) Turns out we can... hooks and Guido's instrumentation module both prove it. If the @prefetch method wraps a template render by capturing which keys are requested we can (atleast to one level of depth) capture which keys are being requested, return mock objects, and do a batch get on them. This could be repeated for all depth levels, till no new keys are being requested. The final render could intercept the gets and return the objects from a map. This would change a total of 200 gets into 3, transparently and without any extra code. Not to mention greatly cut down the need for memcache and help in situations where memcache can't be used. Trouble is I don't know how to do it (yet). Before I start trying, has anyone else done this? Or does anyone want to help? Or do you see a massive flaw in the plan?

• Firing MouseLeftButtonDown event programmatically

  - by RajenK

  Hi, I'm trying to manually fire a MouseLeftButtonDown event on a WPF control programmatically, as I am using the Microsoft Surface SDK, which does not fire MouseLeftButtonDown events, but ContactDown events. Basically I'm trying to push the MouseLeftButtonDown event down to the control, to fire off the correct behavior on the control, while handling a ContactDown event. I'm guessing I have to somehow use the RaiseEvent method on the control to do this with MouseButtonEventArgs, but I'm having some trouble figuring out the parameters. Thanks in advance for your help!
