• opening iWorks documents in iPad UIWebView

  - by user369156

  Hello, I'm writing an iPad application that has a UIWebView which I open word and excel documents in, but I want the user to be able to import those documents into the iWorks applications, Pages and Numbers, just like how you can do it in Safari if you open a document. If you open a document in Safari on the iPad, there'll be a button on the top bar that says "Open in..." and you can choose applications to open in. You get the top bar to appear by tapping on middle of the page. So is there an option you can set to allow UIWebView to show up the bar and automatically detect the content type and populate the list with applications you can import in? Or do I have to build this myself? And if I have to build my own, how do I open URLs to import documents into Pages and Numbers etc? Thanks, -David

• Django: How do I go about changing my simple app to use Ajax?

  - by swisstony

  I currently have a web page where the user enters some data and then clicks a submit button. I process the data in views.py and then use the same Django template to return and display the original data and the results. What I would like to do is try to give it a bit more of a modern look and feel. You know the sort of thing, the page doesn't refresh but displays a spinning disk until the results are displayed. I assume this means using Ajax? How difficult is it to modify a simple app like this to use Ajax? What is involved? What are the best tools to use? JQuery?

• Seeking not working in HTML5 audio tag

  - by lord_wilmore

  I have a lighttpd server running locally. If I load a static file on the server (through an html5 audio tag), it plays and seeks fine. However, seeking doesn't work when running a dev server (web.py/CherryPy) or if I return the bytes via a defined action url instead of as a static file. It won't load the duration either. According to the "HTTP byte range requests" section in this Opera Page it's something to do with support for byte range requests/partial content responses. The content is treated as streaming instead. What I don't understand is: If the browser has the whole file downloaded surely it can display the duration, and surely it can seek. What I need to do on the web server to enable byte range requests (for non-static urls). Any advice would be most gratefully received.

• 1-st level routes for multiple resources in Rails

  - by Leonid Shevtsov

  I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).

• Django: Proper place to unregister ModelAdmins

  - by lazerscience

  Sometimes I need to UNREGISTER some ModelAdmins from the admin site, because I don't want them to be there as they are, eg. if I'm using the Sites framework, and I dont want it to appear in the admin. It's no big deal to e.g. call admin.site.unregister(Site) to do so. In most cases I put it in admin.py of some related app that I have made, but sometimes I end up putting it in a place that hasn't much to do with the original app; another possibility would be making a "dummy app" and put it there... Does anybody know a more descent place where these calls can live?

• User controlled html title tags

  - by zaf

  What are the best practices for allowing a user to maintain the html title tags of all the major pages of his/her site? One way could be to allow the mapping of URLs to some text. For example, we have an app with the following (most complex) url format: http://lang.example.com/searchpage.zaf?a=foo&b=bar&c=RANDOM There are several parts to this: Language sub domain Search page Static parameter 'a' (user may want this in the title) Dynamic and relevant parameter 'b' (user may want this in the title) Dynamic parameter 'c' which can be ignored Never done this before, so I'm asking how you would tackle this!

• Scrapy + Eclipse PyDev : how to setup the debugger?

  - by AsTeR

  I've successfully setup Eclipse with my Scrapy project. I did it by setting a new Run/Debug configuration : Whose main module links to Scrapy /usr/local/bin/scrapy for me (I've found suggestion to use cmdline.py but that failed on my computer (OSX Lion & scrapy installed through easy_install) Defining the arguments to send "crawl ny" in my case as I would if I used the Scrapy command line Setting the correct working directory (${workspace_loc:My Project/src} in my case) Eclipse can successfully launch my project, but I've no debbuger.

• Retrieving a page of that has a redirect

  - by Dmitry Makovetskiyd

  I get my page content with this function: private function fetch_url($url){ $ch=curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 320); $this->doc = curl_exec($ch); $this->status_code= curl_getinfo($ch, CURLINFO_HTTP_CODE); // echo $this->doc; curl_close($ch); } The problem is that with some urls dont exist on a webpage and there is a redirect to another page.. So say if I put the parameter: http://example.com/uncategorized/ It redirect me to : http://example.com/mature/ The problem is with curl, I dont get any content.. But my aim is to get the content of that page redirect.. Is there an easy way to get the function to work in the way I want..?

• Django: where do I call settings.configure?

  - by RexE

  The Django docs say that I can call settings.configure instead of having a DJANGO_SETTINGS_MODULE. I would like my website's project to do this. In what file should I put the call to settings.configure so that my settings will get configured at the right time? Edit in response to Daniel Roseman's comment: The reason I want to do this is that settings.configure lets you pass in the settings variables as a kwargs dict, e.g. {'INSTALLED_APPS': ..., 'TEMPLATE_DIRS': ..., ...}. This would allow my app's users to specify their settings in a dict, then pass that dict to a function in my app that augments it with certain settings necessary to make my app work, e.g. adding entries to INSTALLED_APPS. What I envision looks like this. Let's call my app "rexe_app". In wsgi.py, my app's users would do: import rexe_app my_settings = {'INSTALLED_APPS': ('a','b'), ...} updated_settings = rexe_app.augment_settings(my_settings) # now updated_settings is {'INSTALLED_APPS': ('a','b','c'), 'SESSION_SAVE_EVERY_REQUEST': True, ...} settings.configure(**updated_settings)

• Problem with number/type of arguments passed to an overloaded c++ constructor wrapped with swig.

  - by MiKo

  I am trying to wrap a c++ class (let's call it "Spam") written by someone else with swig to expose it to Python. After solving several problems, I am able to import the module in python, but when I try to create an object of such class I obtain the following error: foo = Spam.Spam('abc',3) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "Spam.py", line 96, in __init__ this = _Spam.new_Spam(*args) NotImplementedError: Wrong number of arguments for overloaded function 'new_Spam'. Possible C/C++ prototypes are: Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action,char const *) Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action) Spam(unsigned char *,unsigned long,bool,unsigned int) Spam(unsigned char *,unsigned long,bool) Spam(unsigned char *,unsigned long) Googling around, I realized that the error is probably caused by the type of the arguments and not by the number (which is quite confusing), but I still cannot identify. I suspect the problem lies in passing a string as the first argument, but have no idea on how to fix it (keep in mind that I know almost no c/c++).

• server reboot has caused django project to lose directories

  - by wmfox3

  A fully functional Django project as well as a couple in development have all broken following the rebooting of the server. In addition to some pieces of the Django admin returning errors as well as missing .js and .css files, I'm getting errors like this when viewing pages that include images uploaded through the admin. Exception Type: TemplateSyntaxError Exception Value: Caught an exception while rendering: (2, 'No such file or directory') Exception Location: /usr/lib/pymodules/python2.6/django/template/debug.py in render_node, line 81 Python Executable: /usr/bin/python Python Version: 2.6.4 So did the reboot stomp on some part of my configuration/setup or did it fail to restart a critical piece?

• Database Error django

  - by Megan

  DatabaseError at /admin/delmarva/event/ no such column: delmarva_event.eventdate I created a class in my models.py file: from django.db import models from django.contrib.auth.models import User class Event(models.Model): eventname = models.CharField(max_length = 100) eventdate = models.DateField() eventtime = models.TimeField() address = models.CharField(max_length = 200) user = models.ForeignKey(User) def __unicode__(self): return self.eventname and now when i try to view my events in my admin or my main_page it gives me the error that there is no eventdate. I tried syncing the db again but nothing changed. Also, I hashtagged eventdate out to see if I get a different error and then it states that delmarva_event.eventtime does not exist as well. I It is weird because it does not have a problem with eventname. Any suggestions would be greatly appreciated!

  Take the following file... ABCD,1234,http://example.com/mpe.exthttp://example/xyz.ext EFGH,5678,http://example.com/wer.exthttp://example/ljn.ext Note that "ext" is a constant file extension throughout the file.

Then I need to capture each URL and put them on their own line with the leading capture. I am working with sed to do this and I cannot figure out how to make it work correctly. Any ideas?

• PHP imap_search not detecting all messages in gmail inbox

  - by Steve

  When I run a very simple imap_search on my GMail inbox, the search returns less messages than it should. Here is the script that anyone with a GMail account can run. $host = '{imap.gmail.com:993/imap/ssl}'; $user = 'foo'; $pass = 'bar'; $imapStream = imap_open($host,$user,$pass) or die(imap_last_error()); $messages = imap_search($imapStream,"ALL"); echo count($messages); imap_close($imapStream); This returns 39 messages. But, I've got 100 messages in my inbox, some in conversations, some forwarded from another account (SquirrelMail, FWIW). Can anyone duplicate these results, and/or tell me what's going on? Other server strings I've tried, all returning the same results: {imap.gmail.com:993/imap/ssl/novalidate-cert} {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX {imap.gmail.com:993/imap/ssl}INBOX GMail's IMAP feature support: http://mail.google.com/support/bin/answer.py?hl=en&answer=78761

• Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

  - by hawk64

  I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

• Getting rid of index.php in the URL when using recess framework and lighttpd

  - by spudnik1979

  I am using the recess php framework with lighttpd Does anyone know how I can use the shorter urls of: http://www.myserver.com/recess Instead of: http://www.myserver.com/index.php/recess The recess readme file says that if I have mod_rewrite I can use the shorter url: -- "Do you have mod_rewrite? -- Yes: Open your browser to the location you unzipped -- No: Open your browser to the location you unzipped followed by index.php" I do have mod_rewrite enabled on lighttpd and i have removed the index.php but I get a 404. Do I need any special rules in my lighttpd.conf?

• Why do i get a 403 error when viewing a Drupal custom menu item via clean url?

  - by Chaulky

  Hi all, I've created a custom menu item in my Drupal 6 website by defining it in a custom module. This is an extremely simple MENU_NORMAL_ITEM menu item. The menu item is defined as /** * Implementation of hook_menu(). */ function menu_test_menu() { $items['menu_test'] = array( 'title' => 'Menu Test', 'page callback' => 'menu_test_hello', 'access callback' => TRUE, 'type' => MENU_NORMAL_ITEM, ); return $items; } Since I have clean URLs on, the path should be www.example.com/menu_test. That URL gives me a 403 error. But, if I enter www.example.com/?q=menu_test, everything works fine. Why am I getting the 403 error? The menu item is useless because it's always trying to go to the clean URL path, which should work but doesn't for some reason. Thanks for the help!

• Automating SSRS Report Deployment

  - by MikeTWebb

  Hello....I have a web site in 3 environments (DEV/TEST/PROD). The Web Site uses SSRS which also has 3 different environments(DEV/TEST/PROD). Currently, I am deploying the reports using the Manual Deployment mechanism provided in the SSRS Solution (i.e., right click a report and click "Deploy"). I have to manually change the Deployment URLs for each environment. Is there a way to Automate this so that reports are automatically deployeed to PROD and TEST if a change occurs in DEV? I've seen some info on RSScripter but it looks a little tricky/clunky...I was hoping for a more succinct/streamlined solution. Thanks MikeTWebb

• guide on crawling the entire web ?

  - by bohohasdhfasdf

  i just had this thought, and was wondering if it's possible to crawl the entire web (just like the big boys!) on a single dedicated server (like Core2Duo, 8gig ram, 750gb disk 100mbps) . I've come across a paper where this was done....but i cannot recall this paper's title. it was like about crawling the entire web on a single dedicated server using some statistical model. Anyways, imagine starting with just around 10,000 seed URLs, and doing exhaustive crawl.... is it possible ? I am in need of crawling the web but limited to a dedicated server. how can i do this, is there an open source solution out there already ? for example see this real time search engine. http://crawlrapidshare.com the results are exteremely good and freshly updated....how are they doing this ?
