• XVal validation framework

  - by csetzkorn

  Hi, I started using this validation framework: http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/ Steve mentions that the DataAnnotationsValidationRunner implementation is slightly naive. Why is this and are there better implementations? I am also looking for a good example that uses this framework to validate database dependent business rules. Any pointers would be very much appreciated. Thanks. Christian

• Have problems designing input and output for a calculator app

  - by zoul

  Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

• Test for absence of an input tag's value attribute

  - by Jeff

  How can I confirm the absence of a HTML attribute in a Rails RSpec test? I can verify that an input tag has a value attribute and that it is an empty string like so: response.should have_tag("input[name=?][value=?]", "user[password]", "") response.should have_tag("input[name=?][value=?]", "user[password_confirmation]", "") But what I want to do is verify that my input fields do not have a value attribute at all (i.e., a blank field).

• MVC Partial View Postback - Jquery validation lost

  - by user415394

  I have a partial view which uses Jquery Valiation. This works OK when initially loaded, however after I do a ajax postback and return the partial view from the server with an error showing, the jquery validation seems to be lost. In that, if I delete a required field and hit save the partial view gets submitted, when I would expect it to show an error message and not get submitted. Does Jquery validation need to be initialised somehow for the form in the partial view?

• When does validation happen in Core Data?

  - by dontWatchMyProfile

  From the docs: If you make changes to managed objects associated with a given context, those changes remain local to that context until you commit the changes by sending the context a save: message. At that point—provided that there are no validation errors—the changes are committed to the store. So does that essentially mean, that validation happens automatically as soon as I call -save?

• How to raise a validation event from a key press

  - by flavour404

  Hi, I want to raise the: private void txtbox_startdate_Validating(object sender, System.ComponentModel.CancelEventArgs e) {} Function from a key leave event. The leave event looks like: private void txtbox_startdate_Leave(object sender, EventArgs e) {} The trouble is of course if I try and call it in this manner: txtbox_startdate_Validating(sender, e) An error is raised because in this case 'e' is an EventArgs whereas the validation function wants a System.ComponentModel.CancelEventArgs and so, how do I convert EventArgs to a System.ComponentModel.CancelEventArgs or create one so that I can call my validation function? Thanks, R.

• Validate input parameters in VB?

  - by EdOxH

  Should I validate input parameters on all functions I create? Input isn't passed from a user, but from other routines as part of an automatic process. I use error handling. I'm not sure what more validating input could do for me. If the input isn't valid, that's pretty much the same thing as an error, isn't it?

• empty() doesn't work with codeigniter input class

  - by BabyAzerty

  This is really weird. Whenever I call something like if(empty($this->input->post("foo")){//blabla} The whole PHP is "down" and I get a blank page from the website (even when I don't pass through this empty(input) line). I know this is not the right method and it is stupid, I change the code to if(!$this->input->post("foo")){//blabla} Better I guess ? Seriously, how come the empty(input) breaks down the entire PHP page ? (I can't get any echo "something").
