  • Hibernate - PropertyNotFoundException: Could not find a getter for ...

    - by Ben Noland
    I have a class that looks like the following: public class MyClass { private String dPart1; public String getDPart1() { return dPart1; } public void setDPart1(String dPart1) { this.dPart1 = dPart1; } } My hibernate mapping file maps the property as follows: <property name="dPart1" not-null="true"/> I get the following error: org.hibernate.PropertyNotFoundException: Could not find a getter for dPart1 in class com.mypackage.MyClass at org.hibernate.property.BasicPropertyAccessor.createGetter(BasicPropertyAccessor.java:282) at org.hibernate.property.BasicPropertyAccessor.getGetter(BasicPropertyAccessor.java:275) at org.hibernate.mapping.Property.getGetter(Property.java:272) at org.hibernate.tuple.entity.PojoEntityTuplizer.buildPropertyGetter(PojoEntityTuplizer.java:247) at org.hibernate.tuple.entity.AbstractEntityTuplizer.<init>(AbstractEntityTuplizer.java:125) at org.hibernate.tuple.entity.PojoEntityTuplizer.<init>(PojoEntityTuplizer.java:55) at org.hibernate.tuple.entity.EntityEntityModeToTuplizerMapping.<init>(EntityEntityModeToTuplizerMapping.java:56) at org.hibernate.tuple.entity.EntityMetamodel.<init>(EntityMetamodel.java:302) at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:434) at It appears that hibernate doesn't like my capitalization.

  • What's the point of some of shoulda's macros?

    - by ryeguy
    I think shoulda is really neat, but what I don't understand is why some of the macros exist, such as: should_validate_uniqueness_of :title should_validate_presence_of :body, :message => /wtf/ should_validate_presence_of :title should_validate_numericality_of :user_id I'm relatively new to testing, but what purpose do these serve? They're almost an exact mirror of the same validations that happen in the model. For example, what exactly do you accomplish by going into your model and writing validates_uniqueness_of :title and then writing a test that says should_validate_uniqueness_of :title?

  • Django: name of many to many items in the admin interface

    - by Adam
    I have a many to many field, which I'm displaying in the django admin panel. When I add multiple items, they all come up as "ASGGroup object" in the display selector. Instead, I want them to come up as whatever the ASGGroup.name field is set to. How do I do this? My models looks like: class Thing(Model): read_groups = ManyToManyField('ASGGroup', related_name="thing_read", blank=True) class ASGGroup(Model): name = CharField(max_length=63, null=True) But what I'm seeing the m2m widget display is:

  • Using Hibernate to do a query involving two tables

    - by Nathan Spears
    I'm inexperienced with sql in general, so using Hibernate is like looking for an answer before I know exactly what the question is. Please feel free to correct any misunderstandings I have. I am on a project where I have to use Hibernate. Most of what I am doing is pretty basic and I could copy and modify. Now I would like to do something different and I'm not sure how configuration and syntax need to come together. Let's say I have two tables. Table A has two (relevant) columns, user GUID and manager GUID. Obviously managers can have more than one user under them, so queries on manager can return more than one row. Additionally, a manager can be managing the same user on multiple projects, so the same user can be returned multiple times for the same manager query. Table B has two columns, user GUID and user full name. One-to-one mapping there. I want to do a query on manager GUID from Table A, group them by unique User GUID (so the same User isn't in the results twice), then return those users' full names from Table B. I could do this in sql without too much trouble but I want to use Hibernate so I don't have to parse the sql results by hand. That's one of the points of using Hibernate, isn't it? Right now I have Hibernate mappings that map each column in Table A to a field (well the get/set methods I guess) in a DAO object that I wrote just to hold that Table's data. I could also use the Hibernate DAOs I have to access each table separately and do each of the things I mentioned above in separate steps, but that would be less efficient (I assume) that doing one query. I wrote a Service object to hold the data that gets returned from the query (my example is simplified - I'm going to keep some other data from Table A and get multiple columns from Table B) but I'm at a loss for how to write a DAO that can do the join, or use the DAOs I have to do the join. FYI, here is a sample of my hibernate config file (simplified to match my example): <hibernate-mapping package="com.my.dao"> <class name="TableA" table="table_a"> <id name="pkIndex" column="pk_index" /> <property name="userGuid" column="user_guid" /> <property name="managerGuid" column="manager_guid" /> </class> </hibernate-mapping> So then I have a DAOImplementation class that does queries and returns lists like public List<TableA> findByHQL(String hql, Map<String, String> params) etc. I'm not sure how "best practice" that is either.

  • Hibernate configuration files not found by Axis2

    - by DanJo519
    I am writing a web service to be deployed on Tomcat using Axis2. I am using Hibernate3 to persist data between the web service and a MySQL database. When running the application through by IDE, the method I am exposing through Axis2 works as intended, however when I deploy the .aar to Tomcat, I receive a SOAP Error claiming that hibernate.cfg.xml cannot be found. However, inside the .aar, I clearly see that all the configuration file and all the mapping files are included. I have determined a workaround: If I place the resulting files from the Netbeans build/class folder into the axis2/WEB-INF/class folder, then the application works as expected. My question, then, is is there a better way to deploy my application so that Axis2 will pick up the configuration and mapping files through the deployed .aar without my manually having to copy the contents of the build/class folder into the axis2/WEB-INF/class folder?

  • Map One-To-One Relationship Doesn't Allow Inserting

    - by nfplee
    Hi, I'm trying to setup a one-to-one mapping from my Users to the UserDetails table. Say I have the following tables in my database: Users: - UserID (PK, Identity) - UserName - Password UsersDetails: - UserID (PK, FK) - FirstName - LastName I have created the following poco classes: public class User { public virtual int UserID { get; set; } public virtual string UserName { get; set; } public virtual string Password { get; set; } public virtual UserDetails Details { get; set; } } public class UserDetails { public virtual int UserID { get; set; } public virtual User User { get; set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public UserDetails() { } public UserDetails(User user) { User = user; } } Which are fluently mapped (please note the xml mapping is very similar and if all you know is the xml mapping then I would still appreciate you guidance): public class UserMap : ClassMap<User> { public UserMap() { Table("Users"); Id(x => x.UserID); Map(x => x.UserName); Map(x => x.Password); HasOne(x => x.Details) .Constrained() .Cascade.All(); } } public class UserDetailsMap : ClassMap<UserDetails> { public UserDetailsMap() { Table("UsersDetails"); Id(x => x.UserID) .GeneratedBy.Foreign("User"); HasOne(x => x.User) .Constrained(); Map(x => x.FirstName); Map(x => x.LastName); } } Everything displays correctly but if I say: var user = new User() { UserName = "Test", Password = "Test" }; user.Details = new UserDetails(user) { FirstName = "Test", LastName = "Test" }; session.Save(user); I get the error: "NHibernate.Id.IdentifierGenerationException: null id generated for: UserDetails." I'd really appreciate it if someone could show me what I've done wrong. Thanks

  • GORM ID generation and belongsTo association ?

    - by fabien-barbier
    I have two domains : class CodeSetDetail { String id String codeSummaryId static hasMany = [codes:CodeSummary] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_set_detail_id', generator: 'assigned' } } and : class CodeSummary { String id String codeClass String name String accession static belongsTo = [codeSetDetail:CodeSetDetail] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_summary_id', generator: 'assigned' } } I get two tables with columns: code_set_detail: code_set_detail_id code_summary_id and code_summary: code_summary_id code_set_detail_id (should not exist) code_class name accession I would like to link code_set_detail table and code_summary table by 'code_summary_id' (and not by 'code_set_detail_id'). Note : 'code_summary_id' is define as column in code_set_detail table, and define as primary key in code_summary table. To sum-up, I would like define 'code_summary_id' as primary key in code_summary table, and map 'code_summary_id' in code_set_detail table. How to define a primary key in a table, and also map this key to another table ?

  • crash in calloc

    - by mmd
    I'm trying to debug a program I wrote. I ran it inside gdb and I managed to catch a SIGABRT from inside calloc(). I'm completely confused about how this can arise. Can it be a bug in gcc or even libc?? More details: My program uses OpenMP. I ran it through valgrind in single-threaded mode with no errors. I also use mmap() to load a 40GB file, but I doubt that is relevant. Inside gdb, I'm running with 30 threads. Several identical runs (same input&CL) finished correctly, until the problematic one that I caught. On the surface this suggests there might be a race condition of some type. However, the SIGABRT comes from calloc() which is out of my control. Here is some relevant gdb output: (gdb) info threads [...] * 11 Thread 0x7ffff0056700 (LWP 73449) 0x00007ffff6a948a5 in raise () from /lib64/libc.so.6 [...] (gdb) thread 11 [Switching to thread 11 (Thread 0x7ffff0056700 (LWP 73449))]#0 0x00007ffff6a948a5 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007ffff6a948a5 in raise () from /lib64/libc.so.6 #1 0x00007ffff6a96085 in abort () from /lib64/libc.so.6 #2 0x00007ffff6ad1fe7 in __libc_message () from /lib64/libc.so.6 #3 0x00007ffff6ad7916 in malloc_printerr () from /lib64/libc.so.6 #4 0x00007ffff6adb79f in _int_malloc () from /lib64/libc.so.6 #5 0x00007ffff6adbdd6 in calloc () from /lib64/libc.so.6 #6 0x000000000040e87f in my_calloc (re=0x7fff2867ef10, st=0, options=0x632020) at gmapper/../gmapper/../common/my-alloc.h:286 #7 read_get_hit_list_per_strand (re=0x7fff2867ef10, st=0, options=0x632020) at gmapper/mapping.c:1046 #8 0x000000000041308a in read_get_hit_list (re=<value optimized out>, options=0x632010, n_options=1) at gmapper/mapping.c:1239 #9 handle_read (re=<value optimized out>, options=0x632010, n_options=1) at gmapper/mapping.c:1806 #10 0x0000000000404f35 in launch_scan_threads (.omp_data_i=<value optimized out>) at gmapper/gmapper.c:557 #11 0x00007ffff7230502 in ??

  • Django: customizing the message after a successful form save

    Hello, whenever I save a model in my Admin interface, it displays the usual "successfully saved message." However, I want to know if it's possible to customize this message because I have a situation where I want to warn the user about what he just saved and the implications of these actions. class PlanInlineFormset(forms.models.BaseInlineFormset): def clean(self): ### How can I detect the changes? ### (self.changed_data doesn't work because it's an inline) ### and display what he/she just changed at the top AFTER the successful save? class PlanInline(admin.TabularInline): model = Plan formset = PlanInlineFormset

  • BlackBerry use of the simulators

    - by user301467
    Hallo, on the BlackBerry homepage you can download different simulators for every different model. There are a lot fo simulators there... My question is, how do you develop BlackBerry applications: do you use the simulators - can you relay on them. If an application works on the simulator, does it works 1:1 on the phone? Do you develop for every model a different UI, as the screensize is different? Thanks you very much for your replay?

  • Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • Create a flexible, localized, Ruby-on-Rails list-of-values

    - by Craig
    I have a list of values (Beginner, Intermediate, Advanced, Fluent, Native) that I would like to: act as the model for a SELECT list act as a model to convert ids to values in a HTML table use in multiple controllers and views keep in an order that preserves the business rules (ordered by skill level) localize at some point in the future Is there a way of implementing this list to address all or most of my needs?
