  • (fluent) nhibernate conditional table mapping strategy

    - by grenade
    I have no control over database schema and have the following (simplified) table structure: CityProfile Id Name CountryProfile Id Name RegionProfile Id Name I have a .Net enum and class encapsulating the lot: public enum Scope { Region, Country, City } public class Profile { public Scope Scope { get; set; } public int Id { get; set; } public string Name { get; set; } } I am looking for a mechanism that allows me to map to the correct table, something like: public class ProfileMap : ClassMap<Profile> { public ProfileMap() { switch (x => x.Scope) { // <--Invalid code here! case Scope.City: Table("CityProfile"); break; case Scope.Country: Table("CountryProfile"); break; case Scope.Region: Table("RegionProfile"); break; } Id(x => x.Id); Map(x => x.Name); } } Or have I approached this wrong?

  • Dynamic find methods Vs conditional statements

    - by piemesons
    Student.find(:all, :conditions => [‘name = ? and status = ?’ ‘mohit’, 1]) Vs Student.find_all_by_name_and_status(‘mohit’, 1) Both the queries will result the same set of row but first one is preferable cause in the second way there will be exception generated method_missing and then rails will try to relate it as dynamic method. if fine then result set to returned. Can any body explain me this in a good manner. What exactly is happening behind the screen. Please correct me if i am wrong.

  • Getting the record ID just added with mysql prepared statements

    - by dmontain
    I'm inserting a record using PDO (very similar to mysqli). $addRecord->execute(); To know if the operation worked, I've learned that I can save it to a variable $result that can be used as true false $result = $addRecord->execute(); if ($result){ //add successful } else { //add unsuccessful } What I'd like to do is also get the record id just added. In the table, each record has an auto_incremented field called id. I tried doing this $new_id = $result['id']; but it seems that $result is purely boolean and doesn't actually hold the actual record that was added. Can someone confirm this and how would I then access the record just added? Note that several people may be adding to the same table at the same time, so I think getting just the last one would not be very accurate.

  • Conditional restart on Activity onConfigurationChanged

    - by yuku
    I want to make an activity that allows orientation changes on some condition, but not otherwise. More exactly I want to prevent restarting the activity when a background thread is busy. I have put the configChanges attribute on the activity manifest, and onConfigurationChanged is called when the orientation changes. However I want to allow the app to change the orientation when allowed. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); if (orientationChangeAllowed) { // how to I restart this activity? } else { // don't do anything } }

  • Questions regarding ordering of catch statements in catch block - compiler specific or language stan

    - by Andy
    I am currently using Visual Studio Express C++ 2008, and have some questions about catch block ordering. Unfortunately, I could not find the answer on the internet so I am posing these questions to the experts. I notice that unless catch (...) is placed at the end of a catch block, the compilation will fail with error C2311. For example, the following would compile: catch (MyException) { } catch (...) { } while the following would not: catch (...) { } catch (MyException) { } a. Could I ask if this is defined in the C++ language standard, or if this is just the Microsoft compiler being strict? b. Do C# and Java have the same rules as well? c. As an aside, I have also tried making a base class and a derived class, and putting the catch statement for the base class before the catch statement for the derived class. This compiled without problems. Are there no language standards guarding against such practice please?

  • sqlite on iphone can open db but not prepare statements

    - by jan
    I'm brand new to using sqlite so I may have missed something basic. I've created a database and copied it into my app's document's directory. I'm able to open it but when I make a call to sqlite3_prepare_v2 I receive SQLITE_ERROR, "SQL error or missing database". here's my code: sqlite3 *database; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { sqlite3_stmt *compiledStatement; NSString *sqlStatement = @"select * from dbname"; int result = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, nil); ... } the same sql statement works in the terminal. I've found this question in a few places either without answers or with solutions that don't fix my problem. I'm hoping someone here will be able to help. Thanks.

  • Mixing regular expression and other conditional expression in a bash if statement

    - by Tassos
    I can't get around this for quite sometime now. As I read along manuals and tutorials I'm getting more confused. I want an if statement with the following logic: if [ -n $drupal_version ] && [[ "$drupal_version" =~ DRUPAL-[6-9]-[1-9][1-9] ]]; then but I can't get it to work properly. When the script is evaluated using the "bash -x ... " script construct, works ok but when is run as a regular script my expression is not evaluated (eventhough the above condition should be met the else part is run). Could you provide any help?

  • maven conditional dependencies

    - by Joshua
    We would like to bundle library dependencies from (Alfresco or Jackrabbit or ...) based on the customer choice. The number of dependencies actually varies based on the chosen vendor. How do we provide hooks at the maven level, so that the final product just includes the dependent jars as per customer selection.

  • Conditional Validation with Paperclip difficult

    - by Michael Schmitz
    Hi, I have an "item", which goes through a multi-page creation process. Images are uploaded at step five, and I keep track of the steps by using the attribute "complete". When validating whether an image is attached with paperclip, I get problems using the code below: validates_attachment_presence :pic1, :if => Proc.new { |u| u.complete == "step5"} It seems that I can't access the "complete" attribute, as the active-record object seems to be the paperclip image. Is there a way for me to check at which point in the process I am and validate conditionally? Thanks, Michael

  • Conditional Drag and Drop Operations in Flex/AS3 Tree

    - by user163757
    Good day everyone. I am currently working with a hierarchical tree structure in AS3/Flex, and want to enable drag and drop capabilities under certain conditions: Only parent/top level nodes can be moved Parent/top level nodes must remain at this level; they can not be moved to child nodes of other parent nodes Using the dragEnter event of the tree, I am able to handle condition 1 easily. private function onDragEnter(event:DragEvent):void { // only parent nodes (map layers) are moveable event.preventDefault(); if(toc.selectedItem.hasOwnProperty("layer")) DragManager.acceptDragDrop(event.target as UIComponent); else DragManager.showFeedback(DragManager.NONE); } Handling the second condition is proving to be a bit more difficult. I am pretty sure the dragOver event is the place for logic. I have been experimenting with calculateDropIndex, but that always gives me the index of the parent node, which doesn't help check if the potential drop location is acceptable or not. Below is some pseudo code of what I am looking to accomplish. private function onDragOver(e:DragEvent):void { // if potential drop location has parents // dont allow drop // else // allow drop } Can anyone provide advice how to implement this?

  • JSF Conditional formatting for onmouseover and such attributes.

    - by Ben
    Hi, I'm trying to format a panelgrid according to a value in the backing bean. I'm currently trying this as the value of the onmouseover attribute: this.className=#{(actions.currentlySelectedActionButton == 0)?'actionButton actionButtonChosen':'actionButton'}; whereas the CSS looks like this: (the relevant parts): .actionButton { width: 100%; height: 20px; border: thin solid #000; cursor:default; } .actionButtonChosen { background-color: blue; } It's not working. Anyone spotting the error would help me greatly. Thanks!

  • Static analysis of multiple if statements (conditions)

    - by koppernickus
    I have code similar to: if conditionA(x, y, z) then doA() else if conditionB(x, y, z) then doB() ... else if conditionZ(x, y, z) then doZ() else throw ShouldNeverHappenException I would like to validate two things (using static analysis): If all conditions conditionA, conditionB, ..., conditionZ are mutually exclusive (i.e. it is not possible that two or more conditions are true in the same time). All possible cases are covered, i.e. "else throw" statement will never be called. Could you recommend me a tool and/or a way I could (easily) do this? I would appreciate more detailed informations than "use Prolog" or "use Mathematica"... ;-)

  • Better way to "find parent" and if statements

    - by Luke Abell
    I can't figure out why this isn't working: $(document).ready(function() { if ($('.checkarea.unchecked').length) { $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('checked').addClass('unchecked'); } else { $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('unchecked').addClass('checked'); } }); Here's a screenshot of the HTML structure: http://cloud.lukeabell.com/JV9N (Updated with correct screenshot) Also, there has to be a better way to find the parent of the item (there are multiple of these elements on the page, so I need it to only effect the one that is unchecked) Here's some other code that is involved that might be important: $('.toggle-open-area').click(function() { if($(this).parent().parent().parent().parent().parent().parent().parent().hasClass('open')) { $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('open').addClass('closed'); } else { $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('closed').addClass('open'); } }); $('.checkarea').click(function() { if($(this).hasClass('unchecked')) { $(this).removeClass('unchecked').addClass('checked'); $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('open').addClass('closed'); } else { $(this).removeClass('checked').addClass('unchecked'); $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('closed').addClass('open'); } }); (Very open to improvements for that section as well) Thank you so much! Here's a link to where this is all happening: http://linkedin.guidemytech.com/sign-up-for-linkedin-step-2-set-up-linkedin-student/ Update: I've improved the code from the comments, but still having issues with that first section not working. $(document).ready(function() { if ($('.checkarea.unchecked').length) { $(this).parents('.whole-step').removeClass('checked').addClass('unchecked'); } else { $(this).parents('.whole-step').removeClass('unchecked').addClass('checked'); } }); -- $('.toggle-open-area').click(function() { if($(this).parent().parent().parent().parent().parent().parent().parent().hasClass('open')) { $(this).parents('.whole-step').removeClass('open').addClass('closed'); } else { $(this).parents('.whole-step').removeClass('closed').addClass('open'); } }); $('.toggle-open-area').click(function() { $(this).toggleClass('unchecked checked'); $(this).closest(selector).toggleClass('open closed'); }); $('.checkarea').click(function() { if($(this).hasClass('unchecked')) { $(this).removeClass('unchecked').addClass('checked'); $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('open').addClass('closed'); } else { $(this).removeClass('checked').addClass('unchecked'); $(this).parent().parent().parent().parent().parent().parent().parent().removeClass('closed').addClass('open'); } });

  • null-coalescing operator or conditional operator

    - by rkrauter
    Which coding style do you prefer: object o = new object(); //string s1 = o ?? "Tom"; // Cannot implicitly convert type 'object' to 'string' CS0266 string s3 = Convert.ToString(o ?? "Tom"); string s2 = (o != null) ? o.ToString() : "Tom"; s2 or s3? Is it possible to make it shorter? s1 does not obviously work.

  • PDO and SQL IN statements

    - by Sai
    Im using a sequel for search like this using PDOs $states = "'SC','SD'"; $sql = "select * from mytable where states in (:states)"; $params = array(':states'=>$states); and I use my function $result = $this->selectArrayAssoc($sql, $params); where my selectArrayAssoc function as following public function selectArrayAssoc($sql, $params = array()){ try{ $sth = $this->db->prepare($sql); $sth->execute($params); $result = $sth->setFetchMode(PDO::FETCH_ASSOC); return $sth->fetchAll(); }catch(PDOException $e){ print $e->getMessage(); //Log this to a file later when in production exit; } } it does not take the quoted variables, I think it is suppressing, in such cases how to deal with this.

  • jQuery / javascript and nested if statements

    - by rayne
    I have a multi-lingual page where I want to display form validation error in the user's language. I use a hidden input to determine which language version the user is browsing like this: <input type="hidden" name="lang" id="lang" value="<?php echo $lang; ?>" /> The PHP side of the script works, but jQuery doesn't seem to realize which language is passed on. It displays the English error message no matter on which language site I am. Here's the code (I removed the other form fields for length): $(document).ready(function(){ $('#contact').submit(function() { $(".form_message").hide(); var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var lang = $("#lang").val(); var name = $("#name").val(); var dataString = { 'lang': lang, 'name': name } if (name == '') { if (lang == 'de') { $("#posted").after('<div class="form_message"><p><span class="error">Fehler:</span> Bitte gib deinen Namen an!</p></div>'); } else { $("#posted").after('<div class="form_message"><p><span class="error">Error:</span> Please enter your name!</p></div>'); } $("#name").focus(); $("#name").addClass('req'); } else { $("#loading").show(); $("#loading").fadeIn(400).html('<img src="/img/loading.gif" />Loading...'); $.ajax({ type: "POST", url: "/contact-post.php", data: dataString, cache: false, success: function(html){ $("#loading").hide(); $("#posted").after('<div class="form_message"><p>Thank you! Your contact request has been sent.</p></div>'); $("#contact input:submit").attr("disabled", "disabled").val("Success!"); } }); }return false; }); }); The problem seems to be somewhere in the nested if statement. Does jQuery / javascript even recognize nested ifs? And if yes, why is it not working?

  • iphone - compiler conditional on header

    - by Mike
    I have a project that generates applications for two targets. One of the targets has to include one additional delegate protocol that should not be present on the other one. So, I have created a macro on Xcode and declared the header like this: #ifdef TARGET_1 @interface myViewController : UIViewController <UIScrollViewDelegate, UIPopoverControllerDelegate> #endif #ifdef TARGET_2 @interface myViewController : UIViewController <UIScrollViewDelegate> #endif { .... bla bla.... } The problem is that Xcode is not liking this "double" declaration of @interface and is giving me all sort of problems. How to solve that? thanks for any help.

  • Conditional configuration in maven pom.xml

    I'd like to ONLY exclude certain files in maven-war-plugin when property "skipCompress" set to true, I thought I could do something like this, but it doesn't work for me. BTW, I can't use profile to achieve this even I want to use skipCompress to turn on and off the compression in both development and deployment profiles. <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <if> <not> <equals arg1="${skipCompress}" arg2 = "true"/> </not> <then> <warSourceExcludes>**/external/dojo/**/*.js</warSourceExcludes> </then> </if> </configuration> </plugin> Thanks, David

  • wordpress conditional statements

    - by codedude
    I am using this code in wordpress to display different content when different pages are loaded. I have 5 pages on the site called Home, Bio, Work, Contact and Notes. The Notes page is being used as a blog. Here is the code I am using. <?php if (is_page('contact')) { ?> get in touch with me <?php } elseif (is_single()) { ?> a note from me <?php } elseif (is_page('notes')) { ?> the notes of me <?php } else { ?> the <?php the_title(); ?> of me <?php } ?> So if it the contact page, it displays "get in touch with me" and if it is a single blog post page it displays "a note from me". However this is where I have a problem. The next statement should display "the notes of me" when it is on the Notes page. However, this does not happen. Instead it shows the default content which is in the "else" statement. any idea on why this is happening?
