  • Passing list of values to django view via jQuery ajax call

    - by finspin
    I'm trying to pass a list of numeric values (ids) from one web page to another with jQuery ajax call. I can't figure out how to pass and read all the values in the list. I can successfully post and read 1 value but not multiple values. Here is what I have so far: jQuery: var postUrl = "http://localhost:8000/ingredients/"; $('li').click(function(){ values = [1, 2]; $.ajax({ url: postUrl, type: 'POST', data: {'terid': values}, traditional: true, dataType: 'html', success: function(result){ $('#ingredients').append(result); } }); }); /ingredients/ view: def ingredients(request): if request.is_ajax(): ourid = request.POST.get('terid', False) ingredients = Ingredience.objects.filter(food__id__in=ourid) t = get_template('ingredients.html') html = t.render(Context({'ingredients': ingredients,})) return HttpResponse(html) else: html = '<p>This is not ajax</p>' return HttpResponse(html) With Firebug I can see that POST contains both ids but probably in the wrong format (terid=1&terid=2). So my ingredients view picks up only terid=2. What am I doing wrong? EDIT: To clarify, I need the ourid variable pass values [1, 2] to the filter in the ingredients view.

  • Which class should store the lookup table?

    - by max
    The world contains agents at different locations, with only a single agent at any location. Each agent knows where he's at, but I also need to quickly check if there's an agent at a given location. Hence, I also maintain a map from locations to agents. I have a problem deciding where this map belongs to: class World, class Agent (as a class attribute) or elsewhere. In the following I put the lookup table, agent_locations, in class World. But now agents have to call world.update_agent_location every time they move. This is very annoying; what if I decide later to track other things about the agents, apart from their locations - would I need to add calls back to the world object all across the Agent code? class World: def __init__(self, n_agents): # ... self.agents = {} self.agent_locations = {} for id in range(n_agents): x, y = self.find_location() agent = Agent(self,x,y) self.agents.append(agent) self.agent_locations[x,y] = agent def update_agent_location(self, agent, x, y): del self.agent_locations[agent.x, agent.y] self.agent_locations[x, y] = agent def update(self): # next step in the simulation for agent in self.agents: agent.update() # next step for this agent # ... class Agent: def __init__(self, world, x, y): self.world = world self.x, self.y = x, y def move(self, x1, y1): self.world.update_agent_location(self, x1, y1) self.x, self.y = x1, y1 def update(): # find a good location that is not occupied and move there for x, y in self.valid_locations(): if not self.location_is_good(x, y): continue if self.world.agent_locations[x, y]: # location occupied continue self.move(x, y) I can instead put agent_locations in class Agent as a class attribute. But that only works when I have a single World object. If I later decide to instantiate multiple World objects, the lookup tables would need to be world-specific. I am sure there's a better solution... EDIT: I added a few lines to the code to show how agent_locations is used. Note that it's only used from inside Agent objects, but I don't know if that would remain the case forever.

  • JQuery Post caused permission denied warning in IE 6 and IE 7

    - by kwokwai
    Hi all, I am using firefox 3 and IE 6, 7 to test if a simple php web page using JQuery Post to pass some data to and from another server web page. $(document).ready(function(){ $("#data\\[User\\]\\[name\\]").click(function(){ var usr=$("#data\\[User\\]\\[name\\]").val(); if(usr.length >= 4){ $("#username").append('<span id="loaderimg" name="loaderimg"><img align="absmiddle" src="loader.gif"/> Checking data availability,&nbsp;please wait.</span>'); var url = "http://mysite.com/site1/toavail/"+usr; $.post( url, function(data) {alert(data);}); }); }); //--> </script> <table border=0 width="100%"> <tr> <td>Username</td> <td> <div id="username"> <input type="text" name="data[User][name]" id="data[User][name]"> </div> </td> </tr> </table> In Firefox 3, the alert box showed empty message.

  • Python base classes share attributes?

    - by tad
    Code in test.py: class Base(object): def __init__(self, l=[]): self.l = l def add(self, num): self.l.append(num) def remove(self, num): self.l.remove(num) class Derived(Base): def __init__(self, l=[]): super(Derived, self).__init__(l) Python shell session: Python 2.6.5 (r265:79063, Apr 1 2010, 05:22:20) [GCC 4.4.3 20100316 (prerelease)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import test >>> a = test.Derived() >>> b = test.Derived() >>> a.l [] >>> b.l [] >>> a.add(1) >>> a.l [1] >>> b.l [1] >>> c = test.Derived() >>> c.l [1] I was expecting "C++-like" behavior, in which each derived object contains its own instance of the base class. Is this still the case? Why does each object appear to share the same list instance?

  • Python Speeding Up Retrieving data from extremely large string

    - by Burninghelix123
    I have a list I converted to a very very long string as I am trying to edit it, as you can gather it's called tempString. It works as of now it just takes way to long to operate, probably because it is several different regex subs. They are as follow: tempString = ','.join(str(n) for n in coords) tempString = re.sub(',{2,6}', '_', tempString) tempString = re.sub("[^0-9\-\.\_]", ",", tempString) tempString = re.sub(',+', ',', tempString) clean1 = re.findall(('[-+]?[0-9]*\.?[0-9]+,[-+]?[0-9]*\.?[0-9]+,' '[-+]?[0-9]*\.?[0-9]+'), tempString) tempString = '_'.join(str(n) for n in clean1) tempString = re.sub(',', ' ', tempString) Basically it's a long string containing commas and about 1-5 million sets of 4 floats/ints (mixture of both possible),: -5.65500020981,6.88999986649,-0.454999923706,1,,,-5.65500020981,6.95499992371,-0.454999923706,1,,, The 4th number in each set I don't need/want, i'm essentially just trying to split the string into a list with 3 floats in each separated by a space. The above code works flawlessly but as you can imagine is quite time consuming on large strings. I have done a lot of research on here for a solution but they all seem geared towards words, i.e. swapping out one word for another. EDIT: Ok so this is the solution i'm currently using: def getValues(s): output = [] while s: # get the three values you want, discard the 3 commas, and the # remainder of the string v1, v2, v3, _, _, _, s = s.split(',', 6) output.append("%s %s %s" % (v1.strip(), v2.strip(), v3.strip())) return output coords = getValues(tempString) Anyone have any advice to speed this up even farther? After running some tests It still takes much longer than i'm hoping for. I've been glancing at numPy, but I honestly have absolutely no idea how to the above with it, I understand that after the above has been done and the values are cleaned up i could use them more efficiently with numPy, but not sure how NumPy could apply to the above. The above to clean through 50k sets takes around 20 minutes, I cant imagine how long it would be on my full string of 1 million sets. I'ts just surprising that the program that originally exported the data took only around 30 secs for the 1 million sets

  • grailsApplication access in Grails unit Test

    - by Reza
    I am trying to write unit tests for a service which use grailsApplication.config to do some settings. It seems that in my unit tests that service instance could not access the config file (null pointer) for its setting while it could access that setting when I run "run-app".

  • Go and a bad prime number algorithm

  • Help! Getting an error copying the data from one column to the same column in a similar recordset..

    - by Mike D
    I have a routine which reads one recordset, and adds/updates rows in a similar recordset. The routine starts off by copying the columns to a new recordset: Here's the code for creating the new recordset.. For X = 1 To aRS.Fields.Count mRS.Fields.Append aRS.Fields(X - 1).Name, aRS.Fields(X - 1).Type, aRS.Fields(X - _ 1).DefinedSize, aRS.Fields(X - 1).Attributes Next X Pretty straight forward. Notice the copying of the name, Type, DefinedSize & Attributes... Further down in the code, (and there's nothing that modifies any of the columns between.. ) I'm copying the values of a row to a row in the new recordset as such: For C = 1 To aRS.Fields.Count mRS.Fields(C - 1) = aRS.Fields(C - 1) Next C When it gets to the last column which is a numeric, it craps with the "Mutliple-Step Operation Generated an error" message. I know that MS says this is an error generated by the provider, which in this case is ADO 2.8. There is no open connect to the DB at this point in time either. I'm pulling what little hair I have left over this one... (and I don't really care at this point that the column index is 'X' in one loop & 'C' in the other... I'll change it later when I get the real problem fixed...)

  • How can I create global context variables in JBOSS?

    - by NobodyMan
    This is a follow-up to a question I posted a while back: "Can I use a single WAR in multiple environments?". I was able to create a single-war solution in Tomcat, but now we are migrating our app to JBoss 4.2 and I can't figure out how to set up global environment variables. In Tomcat 6 this was pretty straightforward: I simply put the following snippet in tomcat/conf/Catalina/myappname.xml: <Context ...> <Environment name="TARGET_ENV" value="DEV" type="java.lang.String" override="false"/> </Context> Then in my app I was able to resolve the environment name with the following: Context context = (Context) InitialContext().lookup("java:comp/env"); String targetEnvironment = (String) context.lookup("TARGET_ENV"); The problem is that I can't find out where/how to place global variables in JBoss. I've tried putting the <Environment> tag in the following files to no avail: server/all/deploy/jboss-web.deployer/context.xml server/default/deploy/jboss-web.deployer/context.xml I know that I can put environment variables in my app's web.xml but that defeats the purpose of having a unified war - I'd still need custom .war's for dev, qa and prod. I'm a JBoss newbie so if there's any additional information that would help just let me know and I'll append to this question. Many thanks! --N

  • Stop Visual Studio from appending numbers to the end of new controls

    - by techturtle
    I am wondering if there is any way to stop Visual Studio 2010 from appending a number to the end of the ID on new controls I create. For example, when I add a new TextBox, I would prefer that it do this: <asp:TextBox ID="TextBox" runat="server"> <asp:TextBox ID="TextBox" runat="server"> <asp:TextBox ID="TextBox" runat="server"> Instead of this: <asp:TextBox ID="TextBox1" runat="server"> <asp:TextBox ID="TextBox2" runat="server"> <asp:TextBox ID="TextBox3" runat="server"> It would make it easier to rename them appropriately, so I don't have to arrow/mouse over and delete the number each time. As I was writing this, the "Questions that may already have your answer" suggested this: How do I prevent Visual Studio from renaming my controls? which admittedly was the biggest part of my annoyance, but that appears to turn off putting in an ID="" field altogether, not just for pasted controls. It would still be helpful to turn off the numbering for new, non-pasted controls and have it not rename pasted ones as well. At the moment I'm working with ASP.NET, but it would be nice if it there was a way to do it for WinForms as well. Before anyone suggests it, I do know that allowing it to append the numbers prevents name conflicts should I not rename them appropriately. However, I would much rather have it fail to compile so I know to fix the issue now (if I forget to name something properly) rather than find random "TextBox1" items lying around in the code later on.

  • Backbone.js routes not firing

    - by drale2k
    I have a Base Router where i define some functions that need to be run everywhere. Every Router extends this Router. Now my problem is, that none of my routes defined in this Base router, actually fire. Every other route in other Routers work fine. I have created a test route called 'a' which calls method 'b', which should fire an alert but nothing happens. Here is the code: (This is Coffeescript, don't pay attention to the indentation, it's fine in my file) class Etaxi.Routers.Base extends Backbone.Router routes: 'register' : 'registerDevice' 'a' : 'b' b: -> alert "a" initialize: -> @registerDevice() unless localStorage.device_id? @getGeolocation() registerDevice: -> @collection = new Etaxi.Collections.Devices() @collection.fetch() view = new Etaxi.Views.RegisterDevice(collection: @collection) $('#wrapper').append(view.render().el) getGeolocation: -> navigator.geolocation.getCurrentPosition (position) -> lat = position.coords.latitude lng = position.coords.longitude #$('#apphead').tap -> # alert 'Position: ' + lat + " ," + lng So when i visit '/register' or '/a' it should fire the appropriate method but it does not. I wonder if it has something to do with the fact that other Router extend from this Router? Would be wired but it is the only thing i can think of because every other Router works fine.

  • Python list should be empty on class instance initialisation, but it's not. Why?

    - by canavanin
    Hi everyone! I would like to create instances of a class containing a list that's empty by default; instead of later setting this list to the final full list I would like to successively add items to it. Here's a piece of sample code illustrating this: #!/usr/bin/python class test: def __init__(self, lst=[], intg=0): self.lista = lst self.integer = intg name_dict = {} counter = 0 for name in ('Anne', 'Leo', 'Suzy'): counter += 1 name_dict[name] = test() name_dict[name].integer += 1 name_dict[name].lista.append(counter) print name, name_dict[name].integer, name_dict[name].lista When I ran the above program I expected to get Anne 1 [1] Leo 1 [2] Suzy 1 [3] as I assumed lista to always be initialised to an empty list. What I got instead was this: Anne 1 [1] Leo 1 [1, 2] Suzy 1 [1, 2, 3] If I replace self.lista = lst by self.lista = [] it works fine, just like when I add the line name_dict[name].lista = [] to the for loop. Why is it that the contents of the previous objects' lists are retained, yet their values of integer aren't? I am rather new to Python, so it would be great if someone could point out to me where my thoughts/assumptions have gone astray. Thanks a lot in advance for your replies.

  • Elegant Disjunctive Normal Form in Django

    - by Mike
    Let's say I've defined this model: class Identifier(models.Model): user = models.ForeignKey(User) key = models.CharField(max_length=64) value = models.CharField(max_length=255) Each user will have multiple identifiers, each with a key and a value. I am 100% sure I want to keep the design like this, there are external reasons why I'm doing it that I won't go through here, so I'm not interested in changing this. I'd like to develop a function of this sort: def get_users_by_identifiers(**kwargs): # something goes here return users The function will return all users that have one of the key=value pairs specified in **kwargs. Here's an example usage: get_users_by_identifiers(a=1, b=2) This should return all users for whom a=1 or b=2. I've noticed that the way I've set this up, this amounts to a disjunctive normal form...the SQL query would be something like: SELECT DISTINCT(user_id) FROM app_identifier WHERE (key = "a" AND value = "1") OR (key = "b" AND value = "2") ... I feel like there's got to be some elegant way to take the **kwargs input and do a Django filter on it, in just 1-2 lines, to produce this result. I'm new to Django though, so I'm just not sure how to do it. Here's my function now, and I'm completely sure it's not the best way to do it :) def get_users_by_identifiers(**identifiers): users = [] for key, value in identifiers.items(): for identifier in Identifier.objects.filter(key=key, value=value): if not identifier.user in users: users.append(identifier.user) return users Any ideas? :) Thanks!

  • How to copy a variable in JavaScript?

    - by Michael Stum
    I have this JavaScript code: for (var idx in data) { var row = $("<tr></tr>"); row.click(function() { alert(idx); }); table.append(row); } So I'm looking through an array, dynamically creating rows (the part where I create the cells is omitted as it's not important). Important is that I create a new function which encloses the idx variable. However, idx is only a reference, so at the end of the loop, all rows have the same function and all alert the same value. One way I solve this at the moment is by doing this: function GetRowClickFunction(idx){ return function() { alert(idx); } } and in the calling code I call row.click(GetRowClickFunction(idx)); This works, but is somewhat ugly. I wonder if there is a better way to just copy the current value of idx inside the loop? While the problem itself is not jQuery specific (it's related to JavaScript closures/scope), I use jQuery and hence a jQuery-only solution is okay if it works.

  • Android Java writing text file to sd card

    - by Paul
    I have a strange problem I've come across. My app can write a simple textfile to SD card and sometimes it works for some people but not for others and I have no idea why. Some people it force closes if they put some characters like "..." in it and such. I cannot seem to reproduce it as I've had no troubles but this is the code that handles it. Can anyone think of something that may lead to problems or a better to way to do it? public void generateNoteOnSD(String sFileName, String sBody){ try { File root = new File(Environment.getExternalStorageDirectory(), "Notes"); if (!root.exists()) { root.mkdirs(); } File gpxfile = new File(root, sFileName); FileWriter writer = new FileWriter(gpxfile); writer.append(sBody); writer.flush(); writer.close(); Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show(); } catch(IOException e) { e.printStackTrace(); importError = e.getMessage(); iError(); } }

  • writing a meta refresh method for rails

    - by aaronstacy
    I want a method in app/controllers/application.rb that can prepend/append text to whatever template gets rendered. Of course I can't call render twice w/o getting a double render error, so is this possible? I want to redirect after a delay using a meta refresh. Here's what I've got: app/controllers/application_controller.rb: def redirect_after_delay (url, delay) @redirect_delay = delay @redirect_url = url render end app/views/layouts/application.html.erb <!DOCTYPE html> <html lang="en"> <head> <%= yield :refresh_tag %> </head> <body> <%= yield %> </body> </html> So then if I want to add a redirect-after-delay, I add the following to 1) my controller and 2) the action's view: app/controllers/my_controller.rb def my_action redirect_after_delay 'http://www.google.com', 3 if some_condition end app/views/my_controller/my_action.html.erb <% content_for :refresh_tag do %> <meta http-equiv='refresh' content='<%=@redirect_delay%>;url=<%=@redirect_url%>'> <% end %> <h1>Please wait while you are redirected...</h1> Since the content_for block never changes, is it possible to do this in some generic way so that I don't have to put <%= yield :refresh_tag %> in each template? (e.g. could redirect_after_delay add it into whatever template is going to be rendered?)

  • Why are changes to classes ignored after dom changes?

    - by Lg102
    I have a price grid that uses relative positioning to move a field around, beneath a box with: overflow: hidden;. In this is field, there are absolute-positioned boxes containing prices. When this box is hovered, the matching values above and left of the will change color. In order to achieve this, a class is toggled using jQuery. This initially works. However, after the grid is moved, the class change doesn't affect the block above the grid anymore. In the Chrome console, i can see the class being added, but it's css-styling isn't applied. No other styles for the element have changed. I am 100% sure there is no other style-rule influencing the element, it just stops responding to the change in class after the DOM has been altered. Can i 'refresh' the DOM somehow? Edit: I've tried to get the relevant code only: Adding the cell in the first place: $("#price_dates_cells").append("<div id='"+weekday[theBeginDate.getDay()]+"-"+theBeginDate.getDate()+"-"+(theBeginDate.getMonth()-1)+"' class='datecell' style='left: "+( Math.floor( difference / ( 3600 * 24 * 1000) ) * ( cellwidth ) )+"px'>"+weekday[theBeginDate.getDay()]+"<br>"+theBeginDate.getDate()+" "+yearmonth[theBeginDate.getMonth()]+"</div>"); Toggle the class: var str_element = "#"+weekday[Bdate.getDay()]+"-"+Bdate.getDate()+"-"+(Bdate.getMonth()-1); $(str_element).toggleClass("red"); and the movement that seems to cause the problem: $('#price_grid').animate({"top": (( ( horizontalMovement ) * cellheight)) }, 'fast', 'linear');

  • Can an ASP.NET user control determine its context or its parent .aspx file

    - by John Galt
    Is it possible for a user control to determine its "context" or its parent .aspx page in some way? Right now I have a user control that is declared on a typical .aspx page as follows: <%@ Register TagPrefix="uc1" TagName="ManageTitle" Src="../UserControls/ManageTitle.ascx" %> The user control currently emits a textbox as follows: <asp:textbox id="txtTitle" runat="server" MaxLength="60" ToolTip="Describe the item with a short pithy title - most important keywords first"/> The page_load for this .ascx file is currently like this: Me.txtTitle.Text = SetPageTitle() While some places in this web app need this (i.e. a textbox where end-user can type a "title"), I have other places where I want to show the "title" information in a "read-only" way. For example, rather than a textbox, I could use a label control or a textbox with Enabled="false" to prevent data entry. I suppose I could clone this small .ascx file and append a suffix to its name like _RO.ascx or something but I am wondering what the best approach would be. In short, can a user control get some sort of "context" from the page that declares it or is there an altogether better way to accomplish this sort of thing? Thank you.

  • Load In and Animate content

    - by crozer
    Hello, I have a little issue concerning an animation-effect which loads a certain div into the body of the site. Let me be more precise: I have a div with the id 'contact': <div id="contact">content</div> The jquery code loads the contents within that div, when I press the link with the id 'ajax_contact': <a href="#" id="ajax_contact">link</a>. The code is working perfectly. However, I want #contact to be HIDDEN when the site loads, i.e. the default state must be non-visible. Only when the user clicks the link #ajax_contact, the div must appear. Please have a look at the jquery code: $(document).ready(function() { var hash = window.location.hash.substr(1); var href = $('#ajax_contact').each(function(){ var href = $(this).attr('href'); if(hash==href.substr(0,href.length-5)){ var toLoad = hash+'.html #contact'; $('#contact').load(toLoad) } }); $('#ajax_contact').click(function(){ var toLoad = $(this).attr('href')+' #contact'; $('#contact').hide('fast',loadContent); $('#load').remove(); $('body').append('<span id="load">LOADING...</span>'); $('#load').fadeIn('normal'); window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5); function loadContent() { $('#contact').load(toLoad,'',showNewContent()) } function showNewContent() { $('#contact').show('normal',hideLoader()); } function hideLoader() { $('#load').fadeOut('normal'); } return false; }); }); I am not sure whether I must change something inside the HTML, but I believe the key is inside the jquery-code. I also tried giving the #contact a CSS style of visible:none, yet this loops and makes the jquery impossible to load the #contact in. I hope I've explained myself well; thank you very much in advance. Chris

  • Can't access dynamically generated div with Jquery

    - by Bug Magnet
    Still trying to get my head around JQuery and dynamically generated content. I have the following code that is dynamically generated with JQuery whenever a user clicks on an 'Add' button: <div id="practices_div" style="border-top: 1px dotted gray"> <br/> <a href="#" class="remove_link" rel="practices_div">Remove</a> ....content goes here </div> The JQuery code that dynamically loads the above content is as follows: $.ajax({ url: '/addAjax.html', success: function(response) { $('#container').append(response); } }); What I'm trying to do is when a user clicks on the Remove link, JQuery should hide and delete the dynamically generated content from the page. The code that does this is as follows: $('.remove_link').live('click', function() { if (confirm("Remove this item?")) { $('#practices_div').fadeOut('medium', function() { $(this).remove(); }); } return false; }); So, when the content is dynamically loaded via Ajax, and I click on the Remove link, the Confirmation dialogue box is displayed and if I confirm, nothing happens. For some reason, JQuery is not able find the dynamically generated #practices_div. Any idea what I may be doing wrong?

  • JQuery Delegate and using traveral options in function

    - by Brian
    I am having trouble figuring out how to use the JQuery delegate function to do what I require. Basically, I need to allow users to add Panels (i.e. divs) to a form dynamically by selecting a button. Then when a user clicks a button within a given Panel, I want to be able to to something to that Panel (like change the color in this example). Unfortunately, it seems that references to the JQuery traversing functions don't work in this instance. Can anybody explain how to achieve this effect? Is there anyway to bind a different delegate to the each panel as its added. $('.addPanels').delegate('*', 'click', function() { $(this).parent.css('background-color', 'black'); $('.placeholder').append('Add item'); }); <div class="addPanels"> <div class="panel"> <a href="#" class="addLink">Add item</a> text</div> <div class="placeholder"/> </div> </div>
