  • django filefield return filename only in template

    - by John
    I've got a field in my model of type FileField. This gives me an object of type type File, which has the following method: File.name: The name of the file including the relative path from MEDIA_ROOT. What I want is something like .filename that will only give me the filename and not the path as well something like: {% for download in downloads %} <div class="download"> <div class="title">{{download.file.filename}}</div> </div> {% endfor %} which would give something like myfile.jpg thanks

  • about service accounts and unregistered users

    - by user1500824
    I have a web app in php mysql, I want to use one google drive account for my app. Can I use my app's accounts instead of google users for privilages. I read in SDK I can use service account to login without promting user, but I don't know how to share or give permissions files for custom users. In api reference I found this: "The user is not necessarily yet a Google user (e.g. if a file or folder is shared with an email address that does not yet have an associated Google account). Example: 1111459233037698895607". How a custom user in my app should get a token for own privilages.

  • How do I get every nth row in a table, or how do I break up a subset of a table into sets or rows of

    - by Jherico
    I have a table of heterogeneous pieces of data identified by a primary key (ID) and a type identifier (TYPE_ID). I would like to be able to perform a query that returns me a set of ranges for a given type broken into even page sizes. For instance, if there are 10,000 records of type '1' and I specify a page size of 1000, I want 10 pairs of numbers back representing values I can use in a BETWEEN clause in subsequent queries to query the DB 1000 records at a time. My initial attempt was something like this select id, rownum from CONTENT_TABLE where type_id = ? and mod(rownum, ?) = 0 But this doesn't work.

  • How do I put a vector inside of a struct in Go?

    - by Brian T Hannan
    I'm trying to put a vector variable inside a struct in Google's Go programming language. This is what I have so far: Want: type Point struct { x, y int } type myStruct struct { myVectorInsideStruct vector; } func main(){ myMyStruct := myStruct{vector.New(0)}; myPoint := Point{2,3}; myMyStruct.myVectorInsideStruct.Push(myPoint); } Have: type Point struct { x, y int } func main(){ myVector := vector.New(0); myPoint := Point{2,3}; myVector.Push(myPoint); } I can get the vector to work in my main function just fine, but I want to encapsulate it inside a struct for easier use.

  • [Java6] Same source code, Eclipse build success but Maven (javac) fails

    - by EnToutCas
    Keep getting this error when compiling using Maven: type parameters of <X>X cannot be determined; no unique maximal instance exists for type variable X with upper bounds int,java.lang.Object Generics type interference cannot be applied to primitive types. But I thought since Java5, boxing/unboxing mechanism works seamlessly between primitive types and wrapper classes. In any case, the strange thing is Eclipse doesn't report any errors and happily compiles. I'm using JDK1.6.0_12. What could possibly be the problem here?

  • How is Magento using the module_name tag elements in the module config file

    - by zokibtmkd
    I found here that Magento is using these tags as custom config variables, but I still cannot understand where are they used and how. For example the Wishlist module has wishlist (same name as the module) xml tag in the config.xml file in which it defines: <item> <product_attributes> <visibility/> <url_path/> <url_key/> </product_attributes> </item> Where is this module using these configurations? Also if I was to build payment method, I have to add in my custom module config.xml a tag for sales and then for quote and so on... I also found other related questions, but most of the answers were that these tags can be anything, but I need to know how they are used by the system. Thank you in advance

  • Sharepoint 2010 search: How to modify search query before submit (programmatically?)

    - by palgo
    Hi, I'm making a custom search box Web Part, similar to the OOTB Web Part from SharePoint (SearchBoxEx class). I'm interested in modifying the search query with additional text before it is submitted, based on a custom checkbox added on the Web Part. Any help on how I can achieve this? UPDATE: I've used the AppendToQuery and AppQueryTerms properties, but this will rewrite the text in the search box as well. I'm interested in passing the values "in the background", maybe as an extra parameter. Point is that the query modification should happen without the user seeing it explicitly.

  • jquery .click function not getting triggered

    - by aakashbhowmick
    I have the following HTML and Javascript code. I am trying to make a search suggestion system. The list-items in the unordered-list 'search_suggest' are retrieved dynamically using ajax as the user types in the input box 'site_search' and inserted. <form name="search_site_form" method="get" action="search.php"> <input id="site_search" name="q" class="search_input input" autocomplete="off" value="Search the site" type="text"/> <ul id="search_suggest"> </ul> <input value=" " type="submit" class="search_submit"/> <script type="text/javascript"> <!-- $("ul#search_suggest>li").click(function(){ alert('123'); }); //--> </script> </form> Clicking on the list items in search_suggest however is not triggering the click function. Any idea why?

  • Javascript/Jquery - Reset text box view area after tab

    - by JK
    I don't know what this is called so its hard to google for it. If you have a plain html input type=text with a small width eg 20 and then type more characters than can be displayed, it shows the last characters you type. And the first ones are scrolled out of view: This is my long text // this is the whole string my long string // this is what is actually visible in the input box How do I make it so that when you hit tab, the view area resets so that the start of the string is visible and the end is hidden? my long string // this is what is visible in the input box when typing This is my // this is what is I want to be visible in the input box after you hit tab What do you call this, and how do you do it?

  • [WordPress 3.1.3] Sreen option is disabled when a plugin is activated

    - by RNorbe
    I'm pretty new to wordpress. I was assigned to create a custom plugin for one of our projects here. The plugin worked as expected and there is no problem activating/deactivating it. When I was exploring the admin panel I noticed that the screen option is off. I read from a blog somewhere that deactivating the plugin one by one to check which plugin has caused this. I did just this and found out that the custom plugin I created was the cause. My question is, is there way to check what have caused this? Some log file I can look into? There is no error message or warning when I activated the plugin and it is giving the output required. This is my first plugin, any advice will be helpful. Btw, this plugin will display a comment (most recent will be shown first) in a widget and there is prev/next navigation to go through the rest of the comments. Thanks, RNorbe

  • setCursor on container without it changing cursor of sub components

    - by Mike
    JPanel panel = new JPanel(null); panel.setSize(400, 400); panel.add(new JButton("Test")); panel.setCursor(Cursor.getCursor(Cursor.SOMETHING_SOMETHING_CURSOR)); The panel will have a custom cursor, but I don't want the button to have a custom cursor. I don't want to have to set the cursor of every sub component, because in my application I have many and I don't want to litter the code with setCursor statements. Is there a way, like overriding a method on the JPanel or something? A "contains" method somewhere is used to determine if a cursor needs to be set. Could I fool it into thinking the mouse is not in the container if it's really in a sub component? Any other nifty little trick?

  • subviews show confused rotated state after a modal dialog is displayed

    - by deafgreatdane
    I've created a custom UIViewController that mimics the UISplitViewController. It manages two child view controllers that get displayed in the left & right body area while in landscape and hides the left to show in a popover when in portrait. It works fine, using the didRotateFromInterfaceOrientation: and willRotateToInterfaceOrientation: messages to reset the location and sizing of the child views. All the views and child controllers are loaded from a nib. This custom view controller is shown inside a UINavigationController. The trouble arises after one of the child view controllers uses presentModalViewController. If the device was rotated after the views were initialized (but before the modal controller is shown), after the modal dialog is dismissed, the left and/or body views will be re-rendered in a different rotation than they were before the modal dialog was changed. I'm wondering if folks have had a similar problem, and what the solution is. I'm sure sample code would be helpful, but it'll take a bunch of work to distill it into a runnable sample.

  • Sequence Point and Evaluation Order( Preincrement)

    - by Josh
    There was a debate today among some of my colleagues and I wanted to clarify it. It is about the evaluation order and the sequence point in an expression. It is clearly stated in the standard that C/C++ does not have a left-to-right evaluation in an expression unlike languages like Java which is guaranteed to have a sequencial left-to-right order. So, in the below expression, the evaluation of the leftmost operand(B) in the binary operation is sequenced before the evaluation of the rightmost operand(C): A = B B_OP C The following expression according, to CPPReference under the subsection Sequenced-before rules(Undefined Behaviour) and Bjarne's TCPPL 3rd ed, is an UB x = x++ + 1; It could be interpreted as the compilers like BUT the expression below is said to be clearly a well defined behaviour in C++11 x = ++x + 1; So, if the above expression is well defined, what is the "fate" of this? array[x] = ++x; It seems the evaluation of a post-increment and post-decrement is not defined but the pre-increment and the pre-decrement is defined. NOTE: This is not used in a real-life code. Clang 3.4 and GCC 4.8 clearly warns about both the pre- and post-increment sequence point.

  • Store data in an inconvenient table or create a derived table?

    - by user1705685
    I have a certain predefined database structure that I am stuck with. The question is whether this structure is OK for ORM or I whether should add a processing layer that would create a more convenient structure every time something is inserted into the original DB. To simplify, here's what it kind of looks like. I have a person table: PersonId Name And I have a properties table: PersonId PropertyType PropertyValue So, for person John Doe... (1, 'John Doe') ...I could have three properties: (1, 'phone', '555-55-55'), (1, 'email', '[email protected]), (1, 'type', 'employee') By using ORM I would like to get a "person" object that would have properties "name", "phone", "email", "type". Can Propel do that? How efficient is it? Is it a better idea to create a table with columns "phone", "email", "type" and fill it automatically as new rows are inserted into the properties table?

  • MVC3 html.TextBox

    - by BigTommy79
    I have login view that takes a LoginPageViewModel: public class LoginPageViewModel : PageViewModel { public string ReturnUrl { get; set; } public bool PreviousLoginFailed { get; set; } public LoginFormViewModel EditForm { get; set; } } which is rendered in the view. When a user tries to log in I only want to post the LoginFormViewModel (Model.EditForm) to the controller: public ActionResult Login(LoginFormViewModel loginDetails) { //do stuff } Using Html.TextBox I can specify the name of the form field manually 'loginDetails.UserName' and post back to the controller and everything works. @model Web.Controllers.User.ViewModels.LoginPageViewModel @using (Html.BeginForm()){ @Html.Hidden("loginDetails.ReturnUrl", Model.ReturnUrl) @Html.LabelFor(x => x.EditForm.UserName, "User Name:") @Html.TextBox("loginDetails.UserName", Model.EditForm.UserName) @Html.ValidationMessageFor(x => x.EditForm.UserName) ..... But what I want to do is to use the staticaly typed helper, something like: @Html.TextBoxFor(x => x.EditForm.UserName) But I'm unable to get this to work. Are you only able to post back the same model when useing the strongly typed helpers? Is there something I'm missing on this? Intellisense doesn't seem to give any clues such as a form field string.

  • Action method expected parameter named Id and nothing otherwise

    - by codingbiz
    The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax
