• Accessing the Identity object in a MVC repository

  - by Rod

  Hi, I have a pretty generic repository that does basic CRUD for many of my business entities. The entities enherit form a generic object that has a few fields I maintain for all objects. eg. ModifiedBy, CreatedBy, CreatedDate, ModifiedDate. These fields ModifiedBy and CreatedBy will always be set before any update/save. My questions is: Is there any way to gain access to the Identity object from my MVC web application in my repositories? I was hoping to set the modifiedby to the identity user for any update in one shot?? Best Regard, Rod

• mysql left outer join

  - by tirso

  hi to all I have two tables employee and timecard, employee table has fields employee_id,firstname,middlename,lastname and timecard table has fields employee_id,time-in,time-out,tc_date_transaction. I want to select all employee records which have the same employee_id with timecard and date is equal with the current date.

• MySQL indexes: how do they work?

  - by bob-the-destroyer

  I'm a complete newbie with MySQL indexes. I have several MyISAM tables on MySQL 5.0x having utf8 charsets and collations with 100k+ records each. The primary keys are generally integer. Many columns on each table may have duplicate values. I need to quickly count, sum, average, or otherwise perform custom calculations on any number of fields in each table or joined on any number of others. I found this page giving an overview of MySQL index usage: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html, but I'm still not sure I'm using indexes right. Just when I think I've made the perfect index out of a collection of fields I want to calculate against, I get the "index must be under 1000 bytes" error. Can anyone explain how to most efficiently create and use indexes to speed up queries? Caveat: upgrading Mysql is not possible in this case. Using Navicat Light for db administration, but this app isn't required.

• Parsing files with python

  - by iHeartDucks

  My input file is going to be something like this key "value" key "value" ... the above lines repeat What I do is read the file contents, populate an object with the data and return it. There are only a set number of keys that can be present in the file. Since I am a beginner in python, I feel that my code to read the file is not that good My code is something like this ObjInstance = CustomClass() fields = ['key1', 'key2', 'key3'] for field in fields: for line in f: if line.find(field) >= 0: if pgn_field == 'key1': objInstance.DataOne = get_value_using_re(line) elif pgn_field == 'key2': objInstance.DataTwo = get_value_using_re(line) return objInstance; The function "get_value_using_re" is very simple, it looks for a string in between the double quotes and returns it. I fear that I will have multiple if elif statements and I don't know if this is the right way or not. Am I doing the right thing here?

• Working with hibernate/DAO problems

  - by Gandalf StormCrow

  Hello everyone here is my DAO class : public class UsersDAO extends HibernateDaoSupport { private static final Log log = LogFactory.getLog(UsersDAO.class); protected void initDao() { //do nothing } public void save(User transientInstance) { log.debug("saving Users instance"); try { getHibernateTemplate().saveOrUpdate(transientInstance); log.debug("save successful"); } catch (RuntimeException re) { log.error("save failed", re); throw re; } } public void update(User transientInstance) { log.debug("updating User instance"); try { getHibernateTemplate().update(transientInstance); log.debug("update successful"); } catch (RuntimeException re) { log.error("update failed", re); throw re; } } public void delete(User persistentInstance) { log.debug("deleting Users instance"); try { getHibernateTemplate().delete(persistentInstance); log.debug("delete successful"); } catch (RuntimeException re) { log.error("delete failed", re); throw re; } } public User findById( java.lang.Integer id) { log.debug("getting Users instance with id: " + id); try { User instance = (User) getHibernateTemplate() .get("project.hibernate.Users", id); return instance; } catch (RuntimeException re) { log.error("get failed", re); throw re; } } } Now I wrote a test class(not a junit test) to test is everything working, my user has these fields in the database : userID which is 5characters long string and unique/primary key, and fields such as address, dob etc(total 15 columns in database table). Now in my test class I intanciated User added the values like : User user = new User; user.setAddress("some address"); and so I did for all 15 fields, than at the end of assigning data to User object I called in DAO to save that to database UsersDao.save(user); and save works just perfectly. My question is how do I update/delete users using the same logic? Fox example I tried this(to delete user from table users): User user = new User; user.setUserID("1s54f"); // which is unique key for users no two keys are the same UsersDao.delete(user); I wanted to delete user with this key but its obviously different can someone explain please how to do these. thank you

• Unwanted virtual keyboard in Blackberry app

  - by matkas

  I have developed a Blackberry app for the 4.5 os series. It works fine on all device except on the storm 1 (storm2 untested). The problem (on the storm) is that the main screen of my application (and all other screens in fact) is shown with the virtual keybord. But there is no text field displayed on the screen that would justify the VK to show up. I have bitmap fields and button fields only on that screen. The use of a single program for all devices (4.5 and up) is seriously preferred. What is causing the VK to show up and what can I do to prevent it (in JDE 4.5)?

• MVC Entity Model not showing my table

  - by Jessica

  I have a database with multiple tables, and some basic relationships. Here is an example of the problem I am having: My Database: **Org** ID Name etc **Detail1** ID D1name **Org_Detail1** Org_ID Detail1_ID **Detail2** ID D2Name **Org_Detail2** Org_ID Detial1_ID BooleanField My problem is, the Org_detail1 table is not showing up in the entity model, but the Org_Details2 table does. I thought it may have been because the Org_Detail1 table only contains two ID fields that are both primary keys, while the Org_Details2 table contains 2 primary key ID fields as well as a boolean field. If I add a dummy field to Org_detail1 and update it, it still won't show up and wont allow me to add a new entity relating to the Org_Detail1 table. The table won't even show up in the list, but it is listed under the tables. Is there any solution to get this table to appear in my model?

• jQuery default/placeholder input text and problems with saved information

  - by user318106

  Hey Guys, I'm new to jQuery and have an annoying problem. I have some login fields that are filled with default text when the field is empty and then removed when clicked. My problem is that when the user has their username/password saved (with browser), if they return to the page the login fields are filled with the users saved input as well as the default input. $('#login input.text').each(function(i, field) { field = $(field); if (field.val().length 0) { field.prev().css('display', 'none'); } field.focus(function() { field.prev().css('display', 'none'); }).blur(function() { if (field.val() == '') field.prev().css('display', 'block'); }); })

• django-uni-form helpers and CSRF tags over POST

  - by linked

  Hi, I'm using django-uni-forms to display my fields, with a rather rudimentary example straight out of their book. When I render the form fields using <form>{%csrf_tag%} {%form|as_uni_form%}</form>, everything works as expected. However, django-uni-form Helpers allow you to generate the form tag (and other helper-related content) using the following syntax -- {% with form.helper as helper %}{% uni_form form helper%}{%endwith%} -- This creates the <form> tag for me, so there's nowhere to embed my own CSRF_token. When I try to use this syntax, the form renders perfectly, but without a CSRF token, and so submitting the form fails every time. Does anyone have experience with this? Is there an established way to add the token? I much prefer the second syntax, for re-use reasons. Thanks!

• Where to learn about VS debugger 'magic names'

  - by Gael Fraiteur

  If you've ever used Reflector, you probably noticed that the C# compiler generates types, methods, fields, and local variables, that deserve 'special' display by the debugger. For instance, local variables beginning with 'CS$' are not displayed to the user. There are other special naming conventions for closure types of anonymous methods, backing fields of automatic properties, and so on. My question: where to learn about these naming conventions? Does anyone know about some documentation? My objective is to make PostSharp 2.0 use the same conventions. Thank you!

• jQuery Validate - Require at least one from group, plus additional items.

  - by Kevin Pullin

  I'm attempting to use 'jQuery Validate' on a form that requires an email address plus either all items of a shipping address completed or none at all. Using the sample provided by the solution to this question: jQuery Validate - “Either skip these fields, or fill at least X of them”, I have been able to successfully solve the validation of the address group. The problem, however, is that the logic for validating the email address field does not work. From debugging the Validate scripts, the "re-entrant" validation code triggered by calling 'fields.data('being_validated', true).valid();' in the linked example results in a reset of all previously validated errors (i.e. the email validation error is cleared). I have modified some existing samples, the first in which removes the offending line and the second with it included. Email Validation Working Email Validation Fails Any tips or suggestions on how to properly solve this or work around the failure?

• Microsoft SQL Server 2008 - 99% fragmentation on non-clustered, non-unique index

  - by user550441

  I have a table with several indexes (defined below). One of the indexes (IX_external_guid_3) has 99% fragmentation regardless of rebuilding/reorganizing the index. Anyone have any idea as to what might cause this, or the best way to fix it? We are using Entity Framework 4.0 to query this, the EF queries on the other indexed fields about 10x faster on average then the external_guid_3 field, however an ADO.Net query is roughly the same speed on both (though 2x slower than the EF Query to indexed fields). Table id(PK, int, not null) guid(uniqueidentifier, null, rowguid) external_guid_1(uniqueidentifier, not null) external_guid_2(uniqueidentifier, null) state(varchar(32), null) value(varchar(max), null) infoset(XML(.), null) -- usually 2-4K created_time(datetime, null) updated_time(datetime, null) external_guid_3(uniqueidentifier, not null) FK_id(FK, int, null) locking_guid(uniqueidentifer, null) locked_time(datetime, null) external_guid_4(uniqueidentifier, null) corrected_time(datetime, null) is_add(bit, not null) score(int, null) row_version(timestamp, null) Indexes PK_table(Clustered) IX_created_time(Non-Unique, Non-Clustered) IX_external_guid_1(Non-Unique, Non-Clustered) IX_guid(Non-Unique, Non-Clustered) IX_external_guid_3(Non-Unique, Non-Clustered) IX_state(Non-Unique, Non-Clustered)

• Error implementing Dynamic Tab with ListView within each Tab - Tabs don't show up

  - by Jon

  I am trying to create a dyanmic tab application that has tabs on the left for each type of Food (e.g. Pasta, Dairy, etc. including those dynamically defined by user) and for each tab, have a listview connected to a SQLite database that updates. This is in the onCreate method: setContentView(R.layout.foodCabinet_layout); dbHelper = new FoodStorageDBHelper(this); dbHelper.open(); Cursor foodTypes = dbHelper.getAllFoodTypes(); ArrayList<String> typeOfFood = new ArrayList<String>(); typeOfFoods.add(foodTypes.getString(1)); while(foodTypes.moveToNext()){ typeOfFoods.add(foodTypes.getString(1)); } final TabHost tbh = (TabHost)findViewById(R.id.food_tabhost_cabinet); tbh.setup(); for(final String s : typeOfFood){ TabSpec nts = tbh.newTabSpec(s); nts.setIndicator(s.replace('_', ' ')); nts.setContent(new TabHost.TabContentFactory(){ public View createTabContent(String tag) { ListView foodCabinetLV = new ListView(FoodCabinet.this); Cursor mCursor = dbHelper.getAllFoodsWithType(s); // Create an array to specify the fields we want to display in the list (only TITLE) String[] from = new String[]{FoodStorageDBHelper.KEY_NAME, FoodStorageDBHelper.KEY_YEAR,FoodStorageDBHelper.KEY_RANK}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.childname,R.id.childyear,R.id.childrank}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(FoodCabinet.this, R.layout.food_row, mCursor, from, to); foodCabinetLV.setAdapter(notes); startManagingCursor(mCursor); foodCabinetLV.setOnItemClickListener( new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(); i.setClass(arg0.getContext(), EditFoodDialog.class); i.putExtra(FoodStorageDBHelper.KEY_ROWID, Long.toString(arg3)); startActivityForResult(i, LoadFoodOrganizer.ACTIVITY_EDIT); } }); return foodCabinetLV; } }); } For some reason, it doesn't show anything... it's a blank screen. Any help would be very much appreciated. Let me know! Thanks! Jon

• Set Pivot Items from Cell Range? Excel 2007

  - by Ben

  I have developed code which identifies the multiple item selections from a Pivot field and writes the list of items to a table. I then wish to take this contents of the list and use it to populate a number of other Pivot Tables on other tabs. I currently have the ability to do this for single Pivot items selections, but I need to do this for multiple selections. If I select multiple items in the Pivot Table and attempt to pass these selections to the other Pivot Tables it creates an error because it sees only hte text "Multiple Items" instead of a list of each item that was checked in the upstream Pivot field. I need some VBA code that allows me to use the list to set another Pivot Field's selections. All the Pivot fields in question here are page fields. I am using Excel 2007. Any help is appreciated. Thanks!

• Update query with conditional?

  - by dmontain

  I'm not sure if this possible. If not, let me know. I have a PDO mysql that updates 3 fields. $update = $mypdo->prepare("UPDATE tablename SET field1=:field1, field2=:field2, field3=:field3 WHERE key=:key"); But I want field3 to be updated only when $update3 = true; (meaning that the update of field3 is controlled by a conditional statement) Is this possible to accomplish with a single query? I could do it with 2 queries where I update field1 and field2 then check the boolean and update field3 if needed in a separate query. //run this query to update only fields 1 and 2 $update_part1 = $mypdo->prepare("UPDATE tablename SET field1=:field1, field2=:field2 WHERE key=:key"); //if field3 should be update, run a separate query to update it separately if ($update3){ $update_part2 = $mypdo->prepare("UPDATE tablename SET field3=:field3 WHERE key=:key"); } But hopefully there is a way to accomplish this in 1 query?

• Can't figure out how to code my css

  Hi, I'm a new poster in stackoverflow. The community seems really nice so I'll go ahead and post my question. I'm trying to style a asp.net MVC2 form so that instead of having all the fields on a strait line, I would like to have it like so: Label: Text field Label: Text field I know you could do that with a table but I would like to use CSS to accomplish that. I know a little bit about css but not enough to figure out what to do. The only thing I came close to was to but my fields as a unorder list then styling the li item. Thank you for your help!

• save managed bean to notes document

  - by Ove Stoerholt

  In a managed bean you have fields, and the fields have getters and setters. But I also need to save values back to, in this case, a Notes profile document. So I have a loadProfileDocument and a saveProfileDocument method. I was thinking of using the bean in the application scope. How do I make sure the profile document is saved? Do I have to call the saveProfileDocument from the setter? Do I call the saveProfileDocument() explisitly? Could I use a destructor (finalize)? Or what...???...

• Wordpress: Not able to retrieve css for new plugin in admin mode

  - by Steven

  I'm creating a new plugin which will have it's own css file. The css file resides in the root folder of the plugin. In the plugin section of the admin interface, I have added a few text fields fields. But the CSS is not applied. I'm adding the CSS file using this code: // Register styling add_action('admin_init', 'event_styles'); function event_styles() { wp_register_style('event_cal', plugins_url('eventcall.css',__FILE__)); wp_enqueue_style('event_cal'); } The following code gives me the CSS path: echo plugins_url('eventcall.css',__FILE__); and outputs http://mysite.com/wp-content/plugins/wp-eventcal/eventcall.css If I try to enter this URL directly in the browser, it only shows me the front page. And if I look in the source code using Firebug, where the link to the CSS should be, I only find the entire HTML code for the front page. Am I using wrong code to use backend in admin interface? In my HOST file, I have added ``

• ResultSet and aggregation

  - by kachanov

  Ok, I admit my situation is special There is a data system that supports SQL-92 and JDBC interface However the SQL requets are pretty expensive, and in my application I need to retreive the same data multiple times and aggregate it ("group by") on different fields to show different dimensions of the same data. For example on one screen I have three tables that show the same set or records but aggregated by City (1st grid), by Population (2nd grid), by number of babies (3rd grid) This amounts to 3 SQL queries (which is very slow), UNLESS anyone of you can suggest any idea any library from apache commons or from google code, so that I can select all records into ResultSet and get 3 arrays of data group by different fields from this single ResultSet. Am I'm missing some obvious and unexpected solution to this problem?

• How to retrieve MYSQL records as an INSERT statement.

  - by Aglystas

  I'm trying come up with the best method of synchronizing particular rows of 2 different database tables. So, for example there's 2 product tables in different databases as such... Origin Database product{ merchant_id, product_id, ... additional fields } Destination Database product{ merchant_id product_id ... additional fields } So, the database schema is the same for both. However I'm looking to select records with a particular merchant_id, remove all records from the destination table that have that merchant_id and replace those records with records from the origin database of the same merchant_id. My first thought was using mysqldump, parsing out the create table statements, and only running the Insert Statements. Seems like a pain though. So I was wondering if there is a better technique to do this. I would think mysql has some method of creating INSERT statements as output from a SELECT statement, so you can define how to insert specific record information into a new db. Any help would be appreciated, thank you much.

• Hibernate criteria with projection not performing query for @OneToMany mapping

  I have a domain object, Expense, that has a field called initialFields. It's annotated as so: @OneToMany(fetch = FetchType.EAGER, cascade = { CascadeType.ALL }, orphanRemoval = true) @JoinTable(blah blah) private final List<Field> initialFields; Now I'm trying to use Projections in order to only pull certain fields for performance reasons, but when doing so the initialFields field is always null. It's the only OneToMany field and the only field I am trying to retrieve with the projection that is behaving this way. If I use a regular HQL query initialFields is populated appropriately, but of course I can't limit the fields. Anyone ever seen anything like this?
