• Filtering foreign keys with AJAX in Django admin

  - by cnobile

  I have most of this figured out already. I have AJAX returning the region/state/province when a country is selected. The correct foreign key is saved to the database, however, when the record is viewed afterwards the selected state is not shown in the select nor are any states for the selected country. I understand why this is happening as, the admin view is not aware of the relation between the state and the country. So here is the question. Is there a hook in the admin view that will allow me to load the correct states for the country and set the selected attribute on the option in the select tag? Or how can I override the admin view for any forms that require the country and region/state/province set? I am using jQuery and Djando-1.1. Thanks

• How to unpack htmlAttributes in a span tag in ASP.NET MVC

  - by sleepy

  I have htmlAttributes generated - originally for the purpose of creating a link with the attribute using Html.ActionLink. Now, based on some condition, I would like to create a <span> tag instead and put the attributes in there. Is there anyway it can be done easily ? Eg: something like: <span <%= htmlAttributes.Unpack() %> > Some txt </span> OR <%= Html.SpanTag("Some txt", htmlAttributes) %> OR anything similar without wresling too much with the already generated htmlAttribues? Thanks

I would prefer to get a pixel value without any major calculation

• immediate=true is set on a jsf command button but still seeing validation

  - by Zack Macomber

  I have the following command button set up in a facelet: <h:commandButton action="#{addressAction.deletePreviousAddress}" value="#{bundle['button.deleteAddress']}" styleClass="deg-form-button" immediate="true"> <f:setPropertyActionListener target="#{addressAction.addressActionForm.previousAddress}" value="#{address}"> </f:setPropertyActionListener> </h:commandButton> In AddressAction, the following code gets run to delete a previous address on the form: public Enum<NavigationConstants> deletePreviousAddress() { addressActionForm.getPreviousAddresses().remove(addressActionForm.getPreviousAddress()); return NavigationConstants.addresses; } Before I made the address input components "required=true", this code worked fine and removed the previous address from the jsf form successfully. Right now, I can't successfully delete a previous address because validation is occurring and stating that the input components need to be filled in on the previous address record on the form. How can I bypass this validation? I thought the "immediate=true" attribute on the command button would have accomplished it but that's not cutting it in my case...

• Lookup Field as a Site Column via CAML

  - by Rob Windsor

  I'm trying to create a Lookup Field as a Site Column via CAML. The list I want to use as the source of the lookup is created in the Feature Receiver so I don't know it's ID. I've read several blog posts that indicate that I can just put the path to the list in the List attribute. It seems from the comments on these post that this solution works for some people but not for others. I'm in the latter group. When I try to associate a content type that uses the lookup site column I: "Exception from HRESULT: 0x80040E07" <Field ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" StaticName="Test_x0020_Lookup_x0020_Column" DisplayName="Test Lookup Column" Type="Lookup" Required="FALSE" List="Lists/Test" ShowField="Title" PrependId="TRUE" Group="Test Site Columns" /> <ContentType ID="0x0100B6D92594DDCE8E479D0EB0C414C463B0" Name="Test Lookup Content Type" Version="0" Group="Test Content Types"> <FieldRefs> <FieldRef ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" Required="TRUE" /> </FieldRefs> </ContentType>

• Table Disobeys W3C Box Model, Ie8 Ignores Fixed Table Width !

  - by Axel Myers

  Hi, I'm having hard time with tables and column widths. Update: I'm using XHTML Strict 1.0. The page is: http://www.pro-turk.net/try The first problem I have is, I have a column with a fixed width of 100px and 4px padding, but it disobeys my padding depending on the value. The column width (as the distance between two borders according to W3C Box Model) is 156 px even if padding is 0 or 4. Only the position of the text changes. According to W3C Box Model ( available at www.pro-turk.net/box_model.png ), borders and paddings aren't included in WIDTH attribute, so why does it render wrongly ? The second problem is, when you look the page I gave with IE8, the first cell in the second row has 150px fixed width, but ie shows it about 50% of the total table width regardless of what i say.

• Fact table with multiple facts

  - by Jeff Meatball Yang

  I have a dimension (SiteItem) has two important facts: perUserClicks perBrowserClicks however, within this dimension, I have groups of dimensions based on an attribute column (let's call the groups AboveFoldItems, LeftNavItems, OnTheFlyItems, etc.) each have more facts that are specific to that group: AboveFoldItems: eyeTime, loadTime LeftNavItems: mouseOverTime OnTheFlyItems: doesn't have any extra, but may in the future Is the following fact table schema ok? DateKey SessionKey SiteItemKey perUserClicks perBrowserClicks eyeTime loadTime mouseOverTime It seems a little wasteful since only some columns pertain to some dimension keys (the irrelevant facts are left NULL). But... this seems like it would be a common problem, so there should be a common solution for this, right?

• ASP.NET client side validation with dataannotations - javascript minimumlength zero

  - by Kordonme

  Hi! I'm doing client side validation on a project I'm working on. Everything works, except for the minimumlength property of the StringLength attribute (it works when submitting and a serverside validation is done): [StringLength(50, MinimumLength = 6)] The javascript generated by Html.EnableClientValication(); is the following: // snip {"FieldName":"User.Password","ReplaceValidationMessageContents":true,"ValidationMessageId":"User_Password_validationMessage","ValidationRules":[{"ErrorMessage":"The field Password must be a string with a minimum length of 6 and a maximum length of 50.","ValidationParameters":{"minimumLength":0,"maximumLength":50},"ValidationType":"stringLength"}]}],"FormId":"form0","ReplaceValidationSummary":false}) The important thing is here: {"minimumLength":0,"maximumLength":50} It produces javascript with the wrong minimumproperty. You guys have a hint? Is this a possible bug?

• Rails 3: Validate combined values

  - by Cimm

  In Rails 2.x you can use validations to make sure you have a unique combined value like this: validates_uniqueness_of :husband, :scope => :wife In the corresponding migration it could look like this: add_index :family, [:husband, :wife], :unique => true This would make sure the husband/wife combination is unique in the database. Now, in Rails 3 the validation syntax changed and the scope attribute seems to be gone. It now looks like: validates :husband, :presence => true Any idea how I can achieve the combined validation in Rails 3? The Rails 2.x validations still work in Rails 3 so I can still use the first example but it looks so "old", are there better ways?

• Accessing a control in asp.net content page through Javascript

  - by rocksolid

  Hi, I have a form in my content page for which I am doing some client side validations via Javascript. The Javascript behaves as expected if I place the JS code directly in the content page. But if I place the JS code in it's own file and try accessing that from the content/master page (through the script tag's src attribute), I get a run time error when the validation function in JS being called. To be specific, I get the below error. Microsoft JScript runtime error: Objected expected/required at this line - document.getElementById('<%=txtemailId.ClientID %').value txtemailId is in the content page. Javascript code is placed in validation.js and accessed via master page. The reason I guess is that when .net is parsing the files, it is unable to substitute txtemailId.ClientID with the client side value that would be generated later on. So, how should one go about it? Thanks!

• Facelets charset problem

  - by Vladimir

  Hi! In my earlier post there was a problem with JSF charset handling, but also the other part of the problem was MySQL connection parameters for inserting data into db. The problem was solved. But, I migrated the same application from JSP to facelets and the same problem happened again. Characters from input fields are replaced when inserting to database (c is replaced with Ä), but data inserted into db from sql scripts with proper charset are displayed correctly. I'm still using registered filter and page templates are used with head meta tag as following: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> If I insert into h:form tag the following attribute: acceptcharset="iso-8859-2" I get correct characters in Firefox, but not in IE7. Is there anything else I should do to make it work? Thanks in advance.

• C# working with decorated members

  - by Ronnie Overby

  Take this class for example: public class Applicant : UniClass<Applicant> { [Key] public int Id { get; set; } [Field("X.838.APP.SSN")] public string SSN { get; set; } [Field("APP.SORT.LAST.NAME")] public string FirstName { get; set; } [Field("APP.SORT.FIRST.NAME")] public string LastName { get; set; } [Field("X.838.APP.MOST.RECENT.APPL")] public int MostRecentApplicationId { get; set; } } How would I go about getting all of the properties that are decorated with the field attribute, get their types, and then assign a value to them?

• ASMX Web Service - "This web service is using http://tempuri.org/ as its default namespace." message

  - by glenatron

  I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't find it mentioned in any configuration page acessible from Visual Studio. And yet it's right there in the wsdl:definitions list for the xmlns:tns attribute on the web service descriptor page when I view it through the browser and as targetNamespace in the same tag. I'm viewing it using Visual Studio's "debug" mode with the built in server from that. Seems like something has got cached somewhere but I can't work out what and where- I've tried stopping and restarting the server, cleaning and rebuilding the service and going through the associated text config files with a text editor but no dice. Any idea what is going on?

• Is there a cross-browser way for tooltips?

  - by Legend

  I am working with d3.js for rendering my graphs. For some reason, I am not a huge fan of svg title because of the delay it incurs and the inability to style them. Please do correct me if I am wrong. I recently came across, tipsy but it does not seem to be cross-browser compatible. For instance, consider this. The tooltips work just fine in Firefox and Chrome but do not appear even in IE 9 and I'm not sure what's going on. Is there a cleaner cross-browser approach for tooltips compatible with d3.js other than using the svg title attribute?

• QuestionOrAnswer model?

  - by Mark

  My site has Listings. Users can ask Questions about listings, and the author of the listing can respond with an Answer. However, the Answer might need clarification, so I've made them recursive (you can "answer" an answer). So how do I set up the database? The way I have it now looks like this (in Django-style models): class QuestionOrAnswer(Model): user = ForeignKey(User, related_name='questions') listing = ForeignKey(Listing, related_name='questions') parent = models.ForeignKey('self', null=True, blank=True, related_name='children') message = TextField() But what bugs me is that listing is now an attribute of the answers as well (it doesn't need to be). What happens if the database gets mangled and an answer belongs to a different listing than its parent question? That just doesn't make any sense. We can separate it with polymorphism: QuestionOrAnswer user message created updated Question(QuestionOrAnswer) shipment Answer(QuestionOrAnswer) parent = ForeignKey(QuestionOrAnswer) And that ought to work, but now ever question and answer is split into 2 tables. Is it worth this overhead for clearly defined models?

• How to combine 2 or more querysets in a Django view?

  - by Espen Christensen

  Hi, I am trying to build the search for a Django site I am building, and in the search I am searching in 3 different models. And to get pagination on the search result list I would like to use a generic object_list view to display the results. But to do that i have to merge 3 querysets into one. How can i do that? Ive tried this: result_list = [] page_list = Page.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term)) article_list = Article.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term) | Q(tags__icontains=cleaned_search_term)) post_list = Post.objects.filter(Q(title__icontains=cleaned_search_term) | Q(body__icontains=cleaned_search_term) | Q(tags__icontains=cleaned_search_term)) for x in page_list: result_list.append(x) for x in article_list: result_list.append(x) for x in post_list: result_list.append(x) return object_list(request, queryset=result_list, template_object_name='result', paginate_by=10, extra_context={'search_term': search_term}, template_name="search/result_list.html") But this doesnt work I get an error when i try to use that list in the generic view. The list is missing the clone attribute. Anybody know how i can merge the three lists, page_list, article_list and post_list?

• How can I access variables outside of current scope in javascript?

  - by sekmet64

  I'm writing some application in javascript and cannot figure it out how to access the variables declared in my function, inside this jquery parse. Inside I can access global variables, but I don't really want to create global vars for these values. Basically I want to extract file names from an xml document in the simulationFiles variable. I check if the node attribute is equal with the simName and extract the two strings inside the xml elements, that part I think it's working. How can I extract those xml elements and append them to local variables? function CsvReader(simName) { this.initFileName = "somepath"; this.eventsFileName = "somepath"; $(simulationFiles).find('simulation').each(function() { if ($(this).attr("name") == simName) { initFileName += $(this).find("init").text(); eventsFileName += $(this).find("events").text(); } }); }
