I have created different entities in JHipster. I want to know if a new database table is created automatically for each entity or I should create them myself?
I read JHipster's Creating an entity but it did not mention about this!
Everything in the list at the top of the page you linked to (Creating an Entity) is created for you. This includes a database table and a liquibase change set, which tracks changes to your database. By default, the table name matches the entity name.
The table is created on your first run of the application after generating the entity. For updates to your tables, see the Liquibase section of the Using in Development docs.
Yes Database table will create automatically,, also you can create database table your self thats your choice

Is there a good practice to introduce existing legacy database tables/entities into a JHipster project?
The idea I had was to create the JPA entities that look exactly like the existing entities and then use the generated artifacts as per normal. Will this possibly work?
In the end, I opted for just creating a view of all the underlying tables I needed in my query. The steps I followed were:
create the view on the DB,
Generate the entity using JHipster, with exactly the same fields.
Strip out the Update ad Create and Delete functions and we have a read-only view page with all the data you need and all the fields displaying, done.
Now I can add my own routers and buttons, to allow other specific operations/flow. This page was my inspiration: https://www.javabullets.com/calling-database-views-from-spring-data-jpa/
I'm migrating a webapp using jhipster so I already have a database with a lot of records that have to be in the new application.
Once I created the entity I added the records from my old database using:
INSERT INTO <table> SELECT * FROM <old-database>.<table>;
When I execute the webapp and search for a record in the entity view it doesn't show any old records (only the ones added using the Add button in the webapp).
I'm using MySQL for dev and prod, and I selected ElasticSearch when I was generating the app. The entity view shows the table with all the old records, but when I search for one using the search box it doesn't find them.
What am I doing wrong? Is that the correct way to insert the data?
using JHipster together with elasticsearch assumes, your app is fully aware of managing its search index. While inserting data on your own, your search index becomes inconsistent to your database, what is obvious.
In your case I suggest to install the JHipster elasticsearch reindexer module, which enables you to reindex the search index at any time you want. After reindexing, your old data should also appear in your JHipster application
I am looking for a way to add or remove Global Navigation items from my sql server database.
I want to know where the data for global navigation is stored in sharepoint 2010 database schema.
I have seen some people (http://sharepointbabe.com/tag/navigation/) used NavNodes table but I can't find this table in my database.
Editing the database directly is really a no-go. Use the API's to manage your environment:
Check this: https://discoveringsharepoint.wordpress.com/2013/03/19/programmatically-set-navigation-settings-in-sharepoint-2013/
It seems that I was looking at a wrong database. That table NavNodes must always exist in Sharepoint website content database. So the database I was looking at was another one which was made to hold membership information and other related information of the website.
I upgraded from VS2005 to VS2012 specifically to code in .Net 4,.Net 4.5, and use EF5. I am new to EF. I have Julie's EF book but it talks mainly about EF4 and POCO and it has me confused trying to implement EF5.
My hosting only allows me to run .Net 4 currently. I am trying to use EF5 on a new database.
I tried Code first to generate my database but I could not get it to generate the database. So I created the database first and then generated the model from the database with EF5. What I want is a layered website using ASP.NET Forms, Data Access Layer, and a Business Layer. The business layer I intend to build so I can use ObjectDataSource to pull in to the webpage along with some web services to use cascading dropdowns.
I have my NameX.edm model created but the tt files don't have the same names, they have Model1.tt and Model1.Context.tt is not the same name, why. Also Model1.Context.tt is empty. I am attempting to create the POCO classes running the EF5 DbContext but I am having trouble getting it to see the edm model. I read somewhere that EF5 creates the POCO automatically. I am not seeing the big picture here. Is my issue that I am not using .Net4.5?
What I have is a ASP.NET Application project, a EF Project, a POCO Project, and intend to have a forth project with the Business logic. How do I get the EF generated correctly and the POCO classes? I want a layered application for to scale well. Next question How to get the POCO classes to talk with the Business logic? My database is SQL. I am use to writing stored proceedures to accomplish everything through business logic.
If you are using Model First technique, make sure that you have references to System.Data.Entity and System.Data.Entity.Design. Also, you will need to create a reference to the EntityFramework.dll as well. It is located by default in c:\Program Files\Microsoft ADO.NET Entity Framework Feature CTP5\Binaries\EntityFramework.dll. If you can not find it, make sure you have installed the Entity Framework through your Package Manager Console. To do this, open up Tools, Library Package Manager, Package Manager Console, then type Install-Package EntityFrameWork.
Next you want to add a new item to your project. Right click on your solution, go to Add, then select New Item. You want to select Data from the Common Items section on the left, then select ADO.NET Entity Data Model.
Next Select Generate From Database. In the next screen, if you have not set up your connection to the server, click New Connection..., otherwise select your database from the drop down box. You need to select whether or not you want to include your connection string information in your config file. This is up to you how secure you need your application to be. If you choose not to, you need to pass this information as parameters in code. Also at the bottom, you will most likely want to change the auto-generated entities name to something easier for you to use. This name will be the name of your DBContext Class!
Next you want to select the tables you would like EF to create POCO's for. If you want all the tables just tick the tables items. Same goes for views and stored procs.
Once you click finish, then you should see all your fancy POCOS laid out in front of you in Design Mode. Note If you do not have primary keys in place for all your tables, I suggest you fix that! VS will spit at you if you do not have Primary Keys set, or if your naming conventions in your tables prevent VS from creating them for you implicitly.
This is a quick little tutorial on getting you up and running. You can now persist and pull data from your POCOS by using your DBContext object. For example if you named your DBContext class *Gary_Bettman_Sucks*, and you wanted to create a new record from your table called NHL you would do the following:
Dim context as New Gary_Bettman_Sucks
Dim PullMyGoalie as New NHL With {
.Goals = 0,
.Playoffs = False
}
context.Set(Of NHL).Add(PullMyGoalie)
context.SaveChanges()
I would Highly suggest you look into implementing the Repository Pattern with your design to encourage code re-use, and it will seriously make your life MUCH easier down the road.
Hope this helps!
I'm using the built-in Domain Catalog database to list all the databases on a particular Domino server. I'm creating a custom view to show certain information about each database. What I'd like to have is a column that displays the creator of each database. However, if the Domain Catalog is keeping track of this information, I can't find it.
Is there a field in the Domain Catalog that provides this information that I just haven't been able to find? Is there some other way I might find this information and get it into this view? #DBlookup and related functions don't work in column formulas.
That information is not stored in the catalog, and is probably not stored in the database either (It's not shown on any of the property tabs).
You would probably need to get/write a server add-in to monitor database creation and store that data somewhere. Then you'd need to account for databases created by adminp/replication - your add-in might pick them up as having been created by a server.
This question was also asked in the R4/R5 forums in 1998 and received no answer.
Interesting question. There is no such attribute for database, but you can dig for some clues.
New databases: use NotesNoteCollection and look for some specific design element (icon, for example) and look for first element in $UpdatedBy field.
New copies/from templates: above mentioned method won't work. It will return info from original/template, not current database. In this case, try using Created property of DB and check user footprints after that date - in ACL log (he probably altered ACL immediately after copy), new design elements (probably made new view, folder, agent...) or profile documents.
What Frantisek said. Looking in the log archive (ugh!) may tell you who deployed it, but in a well run environment that won't be who developed it. A list of $UpdatedBy(0) for all design notes should give you a good idea. The catch will be that it mayl be people who left the company years ago. : )
