• Django: Change models without clearing all data?

  - by Rosarch

  I have some models I'm working with in a new Django installation. Is it possible to change the fields without losing app data? I tried changing the field and running python manage.py syncdb. There was no output from this command. Renavigating to admin pages for editing the changed models caused TemplateSyntaxErrors as Django sought to display fields that didn't exist in the db. I am using SQLite. I am able to delete the db file, then re-run python manage.py syncdb, but that is kind of a pain. Is there a better way to do it?

• How to perform a cell deselection when a user returns to a table view?

  - by Panagiotis Korros

  I am using a UITableView to display a list of cells, when the user selects a cell then a new view appears by using the following code: - (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.navigationController pushViewController: detailsViewController animated: TRUE]; } By using the code above, the view is displayed correctly, but when I return back to the root table view, then the cell is still selected. I noticed, in many sdk examples, that the cell is deselected (with a nice animation) when the root view is poped pack, but I could not find the code that implemented this feature in any of the examples. I know that I can use: [tableView deselectRowAtIndexPath:indexPath animated: YES]; to implement this, but I am very curious on how these examples do it without using any code. Any ideas?

• are shrink-to-fit table cells possible?

  - by Nano8Blazex

  Let's say I have a menu of a prespecified width... I want each menu item to shrink-to-fit with its contents, with the exception of ONE, which then fills up the remaining space in the menu. so like: Fill | item | item | item So far the closest I've come to achieving this effect is by using display:table-cell; in the css code for each menu item. But the problem is unless I define a width for the "item"s, they all expand to take up the same amount of width in the table. Fill | item | item | item | item Is there any way to have the item spaces shrink to fit the item and have the fill just fill up the rest of the div? I might not have asked this very clearly... I'll clarify if needed.

• db optimization - have a total field or query table?

  - by Dorian Fife

  I have an app where users get points for actions they perform - either 1 point for an easy action or 2 for a difficult one. I wish to display to the user the total number of points he got in my app and the points obtained this week (since Monday at midnight). I have a table that records all actions, along with their time and number of points. I have two alternatives and I'm not sure which is better: Every time the user sees the report perform a query and sum the points the user got Add two fields to each user that records the number of points obtained so far (total and weekly). The weekly points value will be set to 0 every Monday at midnight. The first option is easier, but I'm afraid that as I'll get many users and actions queries will take a long time. The second option bares the risk of inconsistency between the table of actions and the summary values. I'm very interested in what you think is the best alternative here. Thanks, Dorian

• Render multiple layers in XNA

  - by Charles

  I'm using XNA, and I've run into a little problem. I need to support multiple layers, each with a distinct z order (I call these "viewports"). A picture is worth a thousand words, so here's what it should look like: There are several things to notice here. Sprites do not render outside of their viewport, as you can see with Sprite B. Also, notice how the viewports are rendered - it's very similar to "layers" in Photoshop. Although Sprite C is has a z order of -1000, C still renders above Sprite A because its viewport's z-order is a greater than A's viewport's z-order. There's one last detail that I couldn't display very well in the above picture. Each viewport needs to optionally render a color over its region of the screen - you could think of it as a "tinting" affect. I'm completely at a loss when it comes to doing this the best way in XNA, so I could really use a short snippet of C#/VB.NET code that demonstrates this in action. Any help would be greatly appreciated.

• Shuffling a list with a constraint

  - by 500

  Preparing a new psychophysic experiment, I have 48 original stimuli displayed 4 times (4 conditions). Resulting in 192 trials. Trying to randomize the order of presentation during the experiment, I need to maximize the distance between the 4 display of the same original stimuli. Please Consider : Table[{j, i}, {j, Range[48]}, {i, Range[4]}] Where j is the original stimuli number and i the condition Output Sample : {{1, 1}, {1, 2}, {1, 3}, {1, 4}, {2, 1}, {2, 2}, {2, 3}, {2, 4}, ... {47, 1}, {47, 2}, {47, 3},{47, 4}, {48, 1}, {48, 2}, {48, 3}, {48, 4}} How could I shuffle the order of presentation of those 192 items, maximizing the distance between identical item with regard to j the original stimuli number ?

• Using a custom URL parameter in Wordpress (with permalinks)?

  - by kiko

  Hello - Is there a way to perhaps edit .htaccess to add a custom URL parameter to Wordpress, so that the parameter is not stripped out by permalinks? I have a Wordpress site with a page that queries a separate (non-Wordpress) database. I passed the URL parameter "pubID" to display individual books and it is working OK. Example: http://www.uglyducklingpresse.org/catalog/browse/item/?pubID=63 But the individual books are not showing up properly in Google - maybe because they all have the same auto-generated "canonical" URL meta tab - one with the "pubID" parameter stripped out. Thank you for any help.

• Is it possible to change the default InputView in MonoTouch?

  - by Pwninstein

  I would like to display a different view than the standard keyboard (a picker control, or a date picker, for example) when a text field becomes first responder (i.e. gets focus). This would be really nice, because currently I'm pushing a custom view which contains my picker control onto the navigation stack where the user chooses an option, and then hits an OK or Cancel button. According to the documentation for UITextField.InputView: Assigning a custom view to this property causes that view to be presented instead. But, It's read only!!! Is there a workaround for this? Do I need to implement a custom UITextField control and somehow override the InputView property? Do I need to call some kind of native function? I'd really love not to have to do either of those things... but if I have to, so be it. Thanks in advance!

• How do I bind functions to all input elements using jQuery?

  - by bakkelun

  Hi, let's say I have this set of HTML-markup and CSS #CSS .inputhelp_text { background: #000; color: #fff; } .nodisplay { display: none; } <input class="inputhelp" id="firstname" /><span class="inputhelp_text nodisplay" id="help_firstname">Write in your firstname</span> <input class="inputhelp" id="lastname" /><span class="inputhelp_text nodisplay" id="help_lastname">Write in your lastname</span> Using jQuery, I need to bind a function to all input fields (I guess using jQuery's EACH function) so that when I click the input field, it should switch the class of each span to only "inputhelp_text". I've gotten this to work in two separate functions for each field, but since I have alot of fields, I know there's a better way to solve it. Any suggestions?

• How to handle huge table ?

  - by misha-moroshko

  I would like to display to user a table which contains ~500,000 rows. The table should be calculated based on a file (i.e. the table is known at the beginning, and does not change). I guess that building the HTML text of this table is not a good idea in terms of memory performance. So how can I build such table ? I would like user to be able to scroll the table using a vertical scroll bar. Is it possible to build on the fly only the visible part of the table ? I'm afraid to see delays because of this. Is it a better idea to use server side programming rather than Javascript ? Any advise would be appreciated.

• Javascript error in Setting focus to a textbox inside a lightbox(Overlay) window.

  - by Rishabh Ohri

  Hi All, I have a textbox, a button and a "AdvancedSearch" link on my aspx page. On page load, the focus is set to the textbox. On click of the "AdvancedSearch" link, a lightbox(overlay) window will be opened. I want to set focus to a textbox present within this lightbox window. I am using javascript to achieve this. The code looks somewhat like this: if( element.type != "hidden" && element.style.display != "none" && !element.disabled ) { element.focus(); return; } when the lightbox window loads, i get a javascript error - "Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus" Any idea why this error is thrown and why it is not able to set focus to the textbox in the lightbox window? Thanks, Rishab.

• How do I show the number of images attached to a post on the image attachment page?

  - by mattloak

  I use the image attachment page to show images attached to a post one by one, in a slideshow sort of affect. I'd like to be able to display the total number of images attached to the parent post and the number of the particular image that's being shown on any given attachment page so you see the picture and the words "Image 3 of 15" for example. I've played around with some different code and can get the total number of images to show on the post page, but when I insert the code on the attachment page template it always shows "1 of 1." I was having this problem a while ago and decided to re-address it, unfortunately I don't have the original code that I used and can't remember it. Anyone have any suggestions?

• How do I get this php statement that gets all the values from database and outputs as checkboxes to

  - by ggfan

  I am a bit lost in all these "" and '' and . in this statement. Basically this query is to get all the tagname from table "tag" and display them for the users as checkboxes. If they have clicked 'submit' and they missed another field(say the title of a post), it would still have the tag they chose displayed. The part I need help with is the echoing part. It doesn't seem to remember the tag when they click submit. $query4 = "SELECT * FROM tags ORDER BY tagname"; $data4 = mysqli_query($dbc, $query4); while ($row4 = mysqli_fetch_array($data4)) { echo "<li><input type='checkbox' name='postingtag[]'"; if (!empty($postingtag)){ echo "value='$postingtag'"; } else{ echo "value='{$row4['tagID']}'"; } echo ">{$row4['tagname']}</li>"; }

• Django Forms save_m2m

  - by John

  Hi I have a model which has 2 many to many fields in it. one is a standard m2m field which does not use any through tables whereas the other is a bit more complecated and has a through table. I am using the Django forms.modelform to display and save the forms. The code I have to save the form is if form.is_valid(): f = form.save(commit=False) f.modified_by = request.user f.save() form.save_m2m() When i try to save the form I get the following error: Cannot set values on a ManyToManyField which specifies an intermediary model. I know this is happening when I do the form.save_m2m() because of the through table. What I'd liek to do is tell Django to ignore the m2m field with the through table but still save the m2m field without the through table. I can then go on to manually save the data for the through table field. Thanks

• How to write a program that mimics Fiddler by using tcpdump or from scratch?

  - by ????

  When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• Mod_rewrite not working properly

  - by James P

  I have this in my .htaccess file... RewriteEngine on RewriteRule ^/invite$ /invite.html It's meant to let a user access this url: http://mysite.com/invite and display the invite.html page. I don't want to redirect the user, but just show them the invite.html page from a better looking URL. When I browse to http://mysite.com/invite though, I get a 404 not found error. Is there anything I'm doing wrong? I've tried looking at tutorials for using mod_rewrite but I seem to be doing what they're telling me too... Thanks!

• Resizing uploaded images based on a maximum width in django (PIL)

  - by AndrewE

  I'm working on a simple message board app in Django that lets people upload images to be displayed in their posts. Since the div containing the posts is only 700px, I want to resize the uploaded images to a max width of something like 680px to save space rather than using css to display an image that's too large within the space constraints. I've been searching this site, google and the PIL docs for a while and haven't found any way of resizing an image on one dimension while maintaining the original aspect ratio. Given my inexperience, it's possible that I'm just not recognizing a solution that's plain to someone who knows what to look for.

  I have a set of jpeg images where eacg image has an associated description. e.g. im1.jpg - suspect enters bank im7.jpg - suspect hands teller a note imj41.jpg - teller gives suspect a bag ... ... It's trivial to view these images individually and see the description but how do I play this as a movie? I need to play the images and when I encounter one with a description, display the description in a status pane. Do I need to convert the images into a movie, if so how? How do I get the player to notify me when the description frame is encountered? I'm using Windows. language doesn't matter, I just need the concept right now.
